1. Field of the Invention
The present invention relates to a communication apparatus capable of a communication through a wireless communication, a communication system having the aforementioned communication apparatus, and a method for controlling the same.
2. Related Background Art
Conventionally, there has been disclosed in U.S. Pat. Nos. 5,720,014 and 6,134,017 a multifunction system, wherein an image input-output apparatus such as a facsimile apparatus is connected to an intelligent terminal by an interface and a service such as a facsimile transmission is provided from the intelligent terminal by using a read function of the facsimile apparatus as a scanner, a record function thereof as a printer, or a communication function.
As disclosed in these Patents, the conventional multifunction system is a system connected through wire such as a serial interface such as RS232, two way parallel port (IEEE1284 standard) such as Centronics or Universal Serial BUS (USB) and the like.
Further, in such a facsimile apparatus, the intelligent terminal takes the initiative in such a manner that the facsimile apparatus returns a response to a command from the intelligent terminal and thus the transmitting and receiving of the control data is performed.
However, in the above described conventional technique, there is a limit to a cable length and, for example, a PC and the facsimile apparatus have to be installed next to each other and the apparatus is not always installed for the user to be able to use it conveniently.
Further, in the case of the above described conventional facsimile apparatus, depending on the function to be realized, there always arises a necessity to poll the state of the facsimile apparatus from the intelligent terminal side and it is necessary to periodically perform the transmitting and receiving of a command for polling the state of the facsimile apparatus and a response thereto.
Hence, a consideration is given to solve the above described problem by connecting the PC and the facsimile apparatus by a standard wireless interface such as a Bluetooth for performing communications.
In this case, when the connection between the intelligent terminal and the interface of the facsimile apparatus is changed from a wire to a wireless interface, the transmitting and receiving of a command for polling the above described state and a response thereto should always be wirelessly performed between the intelligent terminal and the facsimile apparatus. Accordingly, there arises a problem of monopolizing a wireless channel and also consuming an electric power by the transmitting and receiving of the above described command and response.
Further, by performing the polling, after a connection state is brought about for the transmitting and receiving of an image data and a command data between itself and the above described external intelligent terminal, when the transmitting and receiving of the image data and the command data stops, the communication channel remains occupied.
On the other hand, when the channel is not a wired connection using a cable, it is necessary to quickly release the wireless channel. However, in the command system between the conventional intelligent terminal and the facsimile apparatus, there is no command available for the control of the wireless channel. On the contrary, if a command system adding the control command of the wireless channel is adopted, there arises a problem of having no interchangeability with the case of the wired connection.
The above described problem may arise in an image forming apparatus other than the facsimile apparatus.
It is an object of the present invention to enable, without depending on an arrangement or a command for moving to a low electric power consumption state, a wireless connection process portion to be put into a low electric power consumption state and the wireless communication traffic to be reduced.
It is another object of the present invention to reduce the limitation of wirelessly performing other services with other apparatuses inside the same piconet and the electric power consumption at a stand-by time.
It is one aspect of the invention to provide a communication apparatus, including a wireless communication portion configured to wirelessly communicate with another communication apparatus, wherein the wireless communication portion has an active wireless communication mode and a power save wireless communication mode, a change portion configured to change the wireless communication mode of the wireless communication portion, and a display portion configured to display information about the wireless communication mode in accordance with the change of the wireless communication mode by the change portion.

A scanner control task 301, a printer control task 302, a fax control task 303, an MMI (man/machine interface) control task 304 and a phone control task 305 are control tasks of the top layer of the facsimile apparatus 201, and perform device control and control of user operation ports of the facsimile.
A job control task 306 analyzes and allocates jobs from an event control task 307 representing a lower layer for queuing them in the above described control tasks of the top layer.
The event control task 307 analyzes an event received from the lower Bluetooth control task for queuing commands for corresponding to control tasks.
In a Bluetooth control task 308, when information to be sent to the intelligent terminal 202 is received from the upper event control task 307, the information is passed to a lower Bluetooth controller 309.
Also, when information to be sent to an upper layer is received from the lower Bluetooth controller 309, the information is passed to the upper event control task 307. In this way, an operation mode in which the Bluetooth control task 308 passes information to the lower Bluetooth controller 309 when receiving the information from the upper event control task 307, and it passes information to the upper event control task 307 when receiving the information from the lower Bluetooth controller 309 is hereinafter referred to as a command through mode.
Also, in the Bluetooth control task 308, even when information to be sent to the intelligent terminal 202 is received from the upper event control task 307, if it is determined by this task's own determination that the response is given back to the upper layer immediately, the response can be given back to the upper layer without passing the information to the lower layer. This operation mode is hereinafter referred to as a command return mode.
Information received from the upper layer of the Bluetooth controller 309, with respect to the Bluetooth controller 309 and a Bluetooth driver 310, is treated as wireless information to form an air interface, in accordance with the generic access profile of the Bluetooth and its lower concept that is the serial port profile.
An OS 311 is an embedded type operating system of the facsimile apparatus 201, and performs task switching, event management and memory management for the above described software hierarchy for use in this embodiment.
By way of an interface module 408, a Bluetooth control task 409, a Bluetooth controller 410 and a Bluetooth driver 411, the operation structure between the intelligent terminal 202 and the facsimile apparatus 201 is shown.
For control information between the intelligent terminal 202 and the facsimile apparatus 201, the interface module 408 controls exchange of information of a facsimile manager 401, a printer application 404, a scanner application 406, etc. in the upper layer via an inbox 402, an outbox 403, a printer driver 405 and a scanner driver 407, as exchange of information between the intelligent terminal 202 and the facsimile apparatus 201.
Regardless of whether the control is performed by the facsimile manager 410 or by one of the drivers, the interface module 408 manages transfer of facsimile images to be sent, images to be scanned, etc. read of facsimile received images and transfer of images to be printed.
In a Bluetooth control task 409, when information to be sent to the facsimile apparatus 201 is received from the interface module 408, the information is passed to the lower Bluetooth controller 410. Also, when information to be sent to the interface module 408 is received from the lower Bluetooth controller 410, the information is passed to the interface module 408. This operation mode is hereinafter referred to as a command through mode.
Also, in the Bluetooth control task 409, even when information to be sent to the facsimile apparatus 201 is received from the upper interface module, if it is determined by this task's own determination that the response is given back to the upper layer immediately, the response can be given back to the upper layer without passing the information to the lower layer, and this operation mode is hereinafter referred to as the command return mode.
Information received from the upper layer of the Bluetooth controller 410, with respect to the Bluetooth controller 410 and a Bluetooth driver 411, is treated as wireless information to form an air interface, in accordance with the generic access profile of the Bluetooth and its lower concept that is the serial port profile.
An OS 412 is an operating system in the intelligent terminal 202 and receives services of control of MMI and applications on the intelligent terminal 202, in a fundamental part of the service of control of the above described hierarchy MMI and applications for use in the above described embodiment.
Assume that the power of the facsimile apparatus 201 is already turned on at this time.
When the power of the intelligent terminal 202 is turned on, the facsimile manager 401 corresponding to Bluetooth is started to perform processing to make connections with the facsimile apparatus 201.
To ensure that the facsimile apparatus 201 with which a connection is made can perform communication, the Bluetooth control task 409 sends an inquiry sending request to the Bluetooth controller 410. At this time, class of device information in an inquiry command is sent as a serial communication terminal. When receiving the inquiry sending request, the Bluetooth controller 410 carries out an inquiry procedure in accordance with a Bluetooth connection procedure, and notifies the Bluetooth control task 409 of the result thereof (inquiry result).
When receiving the inquiry result, the Bluetooth control task 409 determines from the contents whether or not a connection with the facsimile apparatus 201 can be made, and if it is determined that the connection can be made, it designates an address of the facsimile apparatus 201 and makes a connection request to the Bluetooth controller 410. If the connection is unsuccessful or the facsimile apparatus with which a connection is made is not found, from the contents of the inquiry result, a message showing that fact is displayed on a display unit of the intelligent terminal 202.
When receiving the connection request, the Bluetooth controller 410 establishes a connection using the serial port profile and forms a Piconet, based on the Bluetooth controller 309 of the facsimile apparatus 201 and the specification of Bluetooth.
When the connection is established, notification of the result is provided to the Bluetooth control task 409. When detecting the fact that the connection with the facsimile apparatus 201 could be established from the result of the connection, the Bluetooth control task 409 transmits a ready signal to the facsimile manager 401, and transits the state to the through mode in which the command from the facsimile manager 401 is directly passed to the Bluetooth controller 410.
Also, when receiving a massage showing the fact that establishment of the connection ended in failure from the result of the connection, the Bluetooth control task 409 displays the fact on the display unit of the intelligent terminal 202.
The Bluetooth controller 309 of the facsimile apparatus 201 notifies the Bluetooth control task 308 of the result of the procedure of establishment of the connection with the intelligent terminal 202. When ensuring from the result of the connection establishment that the connection has been established, the Bluetooth control task 308 enters the command through mode to wait for the command from the intelligent terminal 202 in order to pass the command from the intelligent terminal 202 directly to the event control task 307. If connection is unsuccessful, the Bluetooth control task 308 is a wait state until the connection is established.
When receiving the ready signal from the Bluetooth control task 409, the facsimile manager 401 sends to the Bluetooth control task 409 a command to transfer data such as dates of the intelligent terminal 202 and names registered in the facsimile manager 401 to the facsimile apparatus 201.
The Bluetooth control task 409 transfers the received command directly to the Bluetooth controller 410, and the Bluetooth controller 410 transfers it to the facsimile apparatus 201 using the serial port profile.
The Bluetooth controller 309 of the facsimile apparatus 201 sends to the Bluetooth control task 308 the command sent from the intelligent terminal 202 and the Bluetooth control task 308 passes the command directly to the event control task 307. The event control task 307 analyzes the received command and sends the result thereof to the Bluetooth control task 308.
When the initialization process is ended, the facsimile manager 401 issues a reception information acquirement command to check whether or not the facsimile apparatus 201 has a received image. The event control task 307, which receives the reception information acquirement command, searches an image management record stored in the RAM 103 as to whether or not the received image exists.
If the received image is present, a response of “image existed” is given back to the reception information acquirement command issued by the Bluetooth control task 308, and if the received image does not exist, a response of “image not existed” is given back.
When the facsimile manager 401 determines by the response of the reception information acquirement command that the image exists, it performs received image transfer processing in accordance with the process in
If the image does not exist, the facsimile manager 401 issues a state information acquirement command to have the state of the facsimile apparatus 201 stored. The event control task 307, which receives the state information acquirement command, checks states as to the facsimile apparatus 201, such as the state of the printer, the state of the scanner and the state of the memory, and gives back the results.
If the facsimile manager 401 determines from the response of the state information acquirement command that the state of error is found, it displays a message showing the state of error on the display unit of the intelligent terminal 202 and issues periodically the reception information acquirement command and the state information acquirement command to the event control task 307 until the error is corrected.
If the received image does not exist, and the state of the facsimile apparatus 201 is normal, the facsimile apparatus 201 makes transition to the Park mode since the communication between the intelligent terminal 202 and the facsimile apparatus 201 does not need to be connected until reception occurs at the facsimile apparatus 201. The “Park mode” is a Park mode being a low power consumption mode based on the Bluetooth specification, in which the facsimile apparatus 201 that is a slave terminal of the intelligent terminal 202 being a master based on the Bluetooth specification receives a signal from the master only at a certain interval to maintain synchronization in the Piconet. Also, when the transition to the Park mode is made, data communication between the master and the slave cannot be performed, and if data communication is to be performed, the Park mode should be released to make transition to the active mode.
An operation of transition of the facsimile apparatus 201 to the Park mode (low power consumption mode) will now be described. This operation is shown in the latter part of
First, the Bluetooth control task 308 of the facsimile apparatus 201 requests transition to the Park mode to the Bluetooth controller 309. The Bluetooth controller 309, which receives the request for transition to the Park mode, carries out a procedure for transition to the Park mode based on the specification of the Bluetooth, in concert with the Bluetooth controller 410.
When the procedure for transition to the Park mode is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition of the facsimile apparatus 201 to the Park mode.
When notified of the transition to the Park mode, the Bluetooth control tasks 308 and 409 go into command return modes, respectively.
The Bluetooth control task 409 of the intelligent terminal 202, which goes into the command return mode, performs processing similar to the processing in the event control task 307 of the facsimile apparatus 201 connected with cables such as a serial interface such as RC232C and a parallel interface such as Centronics (a standard interface defined in IEEE 1284, etc.). The Bluetooth control task 409 gives back responses such as “image presence information” and “normal/abnormal states” to the information acquirement command and the reception information acquirement command that are issued periodically from the facsimile manager 401, based on facsimile status information stored in the RAM 103 of the intelligent terminal 202.
The Bluetooth control task 308 of the facsimile apparatus 201 performs operation similar to the operation in the facsimile manager 401 in the intelligent terminal 202 when it is connected with the above described cable. The Bluetooth control task 308 of the facsimile apparatus 201 issues periodically the reception information acquirement command and the state information acquirement command to the event control task 307 in order to monitor at every time changes of states of the facsimile apparatus 201 and whether or not the image has been received from some other facsimile apparatus via the communication line 203. When receiving the reception information acquirement command and the state information acquirement command from the Bluetooth control task 308, the event control task 307 gives back reception information (for example, image “absent”) and state information (for example, “normal state”) as a response.
If it is defined that the received image is not transferred to the intelligent terminal 202 during initialization process or when registered data is changed with the intelligent terminal 202 and the registered data is transferred to the facsimile apparatus 201, the facsimile manager 401 and the Bluetooth control task 308 of the facsimile apparatus 201 do not issue the reception information acquirement command and the state information acquirement command.
The Bluetooth control task 308 of the facsimile apparatus 201 is in the command return mode during stand-by, namely during the Park mode, and issues periodically the state information acquirement command and the reception information acquirement command to the event control task 307 to monitor the state of the facsimile apparatus 201. The event control task 307 searches the image management record stored in the RAM 103 as to whether or not the received image exists. When the received image exists, a response of “image existed” is given back to the reception information acquirement command that is issued by the Bluetooth control task 308.
When receiving the response of “image existed”, the Bluetooth control task 308 releases the Park mode to form the Piconet again, and recovers communication between the facsimile apparatus 201 and the intelligent terminal 202 in order to transfer the reception image to the intelligent terminal 202.
For recovering the communication, a request for return to Active is sent to the Bluetooth controller 309. The Bluetooth controller 309, which receives the request for return to Active, communicates with the Bluetooth controller 410 of the intelligent terminal 202 in accordance with a communication recovering procedure of the Bluetooth. When the communication is recovered, the Bluetooth controller 309 gives mode change notification to the Bluetooth control task 308. If the Bluetooth control task 308, which receives the mode change notification, determines form the contents thereof that the communication has been recovered, it makes transition from the command return mode to the command through mode. If determining that the communication cannot be recovered, it keeps the state of the command return mode.
Similarly, the Bluetooth controller 410 of the intelligent terminal 202 gives mode change notification to the Bluetooth control task 409. If the Bluetooth control task 409, which receives the mode change notification, determines from the contents thereof that the communication has been recovered, it makes transition from the command return mode to the command through mode. If determining that the communication cannot be recovered, it keeps the state of the command return mode, and displays a message showing the fact on the display unit of the intelligent terminal 202.
When the communication is recovered, and each of the Bluetooth control tasks 308 and 409 goes into the command through mode, the communication between the facsimile apparatus 201 and the intelligent terminal 202 is performed to carry out reception image data transfer procedure, based on the Bluetooth specification. Furthermore, for the command interface at this time, reception image data transfer procedure is performed with a command interface same as the command interface when connected with cables such as a serial interface such as RS232 C and a parallel interface such as Centronics (standard interface defined in IEEE 1284, etc.).
When the image data transfer processing is completed, the facsimile manager 401 issues the reception information acquirement command to the facsimile apparatus 201 to check whether or not the received image exists. The event control task 307, which receives the reception information acquirement command searches the image management record stored in the RAM 103 as to whether or not the received image exists. If the received image exists, a response of “image existed” is given back, and if the received image does not exist, a response of “image not existed” is given back.
If determining by the response of the reception information acquirement command that the image existed, the facsimile manager 401 performs again received image transfer processing.
If the received image does not exist, the facsimile manager 401 issues the state information acquirement command to have the state of the facsimile apparatus 201 stored. The event control task 307, which receives the state information acquirement command, checks states as to the facsimile apparatus 201 such as the state of the printer, the state of the scanner and the state of the memory, and gives back the result thereof.
If the facsimile manager 401 determines based on the response of the state information acquirement command that the state of error is found, it displays a message showing the state of error on the display of the intelligent terminal 202 and issues periodically the reception information acquirement command and the state information acquirement command to the event control task 307 until the error is corrected. When it is determined that the state of the facsimile apparatus 201 is normal, the state information acquirement command and the reception information acquirement command are periodically issued until transition is made to the Park mode being a low power consumption mode again.
When determining that the state is normal, the facsimile apparatus 201 makes transition to the Park mode being a low power consumption mode.
The Bluetooth control task 308 of the facsimile apparatus 201 requests transition to the Park mode to the Bluetooth controller 309. The Bluetooth controller 309, which receives the request for transition to the Park mode, carries out a procedure for transition to the Park mode based on the specification of the Bluetooth, with the Bluetooth controller 410.
When the procedure for transition to the Park mode is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode.
When notified of the transition to the Park mode, the Bluetooth control tasks 308 and 409 go into command return modes, respectively.
Again, the command return mode is maintained until the user starts service such as facsimile transmission, scanning or print at the intelligent terminal 202, or reception occurs at the facsimile apparatus 201.
In the operation of reception image data transfer service, a file ID acquirement command is first sent from the intelligent terminal 202. When receiving the file ID acquirement command, the facsimile apparatus 201 examines the RAM 103, sets a receipt number associated with reception image data to a parameter as a file ID, and sends the same to the intelligent terminal 202 along with the answer of “OK”.
If the file ID is set with the answer parameter of the file ID acquirement command, the intelligent terminal 202 sets a file ID to be transferred, and sends a file information acquirement command. When receiving the file information acquirement command, the facsimile apparatus 201 sets a file attribute of a designated file ID and the number of pages to the parameter, and sends the above described parameter to the intelligent terminal 202 along with the answer of “OK”. If the designated file ID do not exist, the answer of “NG” is given back.
Then, when receiving the page information acquirement command in which the file ID and the page number are designated, the facsimile apparatus 201 sets to the parameter information such as main/sub scan resolution of the page designated from management information of the RAM 103, and sends the answer of “OK”. If the designated file ID and page do not exist, the answer of “NG” is given back.
When receiving the answer of “OK” for the page information acquirement command, the intelligent terminal 202 sends a page transfer request command, and subsequently sends a parameter to which the file ID and page number to be transferred are set. If the page of the designated file ID is accumulated in the image memory 104, the facsimile apparatus 201 sends the answer of “OK”, and if they do not exist in the image memory 104, the facsimile apparatus 201 sends the answer of “NG”.
When receiving the answer of “OK” to the page transfer request command, the intelligent terminal 202 sends a requested page designation command, and subsequently sends to the facsimile apparatus 201 a parameter to which the main/sub scan resolution and data format acquired with the page information acquirement command is set. The facsimile apparatus 201 examines whether or not the contents of the received parameter matches the contents of management information of the RAM 103, and sends the answer of “OK” if the contents match each other, and sends the answer of “NG” if the contents do not match each other.
Thereafter, the intelligent terminal 202 issues an image data transfer request. The facsimile apparatus 201 transfers image data of predetermined size to the intelligent terminal 202 from the image memory 104, and along therewith sends the answer of “OK”.
After transfer of one page is completed, the intelligent terminal 202 puts the transferred reception image in the inbox 402, and displays the image so that the completion of the transfer of the received image and the contents of the received image can be recognized.
Then, a page erase command is issued. The facsimile apparatus 201 which receives the page erase command erases the image data of the designated page from the image memory 104, modifies the management information of the RAM 103, and sends the answer of “OK”.
The above described operation is repeated until reception image data of all pages are transferred, and when reception image data of all pages are transferred, a file erase instruction command is accepted to erase the management information of the designated file, and the process is ended.
In
The above described “command through mode” is an operation mode in which a command is sent to the Bluetooth controller 410 when this command is received from the facsimile manager 401, and a response is sent to the facsimile manager 401 when the response is received from the Bluetooth controller 410.
The above described process is carried out, and start-up of the intelligent terminal 202 is waited.
When the power of the intelligent terminal 202 is turned on, the facsimile manager 401 is started, and the Bluetooth control task 409 sends an Inquiry to the facsimile apparatus 201 via the Bluetooth controller 410 at step S801.
At S802, whether or not the facsimile apparatus 201 has responded to the sent Inquiry, and if it has responded normally, the process proceeds to S804, and if it has not responded normally, the process proceeds to S803.
At S803, by displaying on the display unit of the intelligent terminal 202 the fact that there exists no connectable facsimile apparatus, notification is made and the process is ended.
At S804, a connection request is sent to the Bluetooth controller 410, and the process proceeds to S805.
At S805, a response to the connection request is waited, and the process proceeds to S806 if notification of failure in connection request is given from the facsimile apparatus 201 via the Bluetooth controller 410, and the process proceeds to S807 if notification of success in connection is given.
At S806, notification of the failure in connection to the facsimile apparatus 201 is made using the display unit of the intelligent terminal 202 and the process is ended.
At S807, the Bluetooth control task 409 notifies the facsimile manager 401 of Ready showing that connection to the facsimile apparatus could be established, and at S808, transition to the “command through mode” is made.
As described above, the “command through mode” is an operation mode in which a command is sent to the Bluetooth controller 410 when the Bluetooth control task 409 receives this command from the facsimile manager 401, and a response is sent to the facsimile manager 401 when the response is received from the Bluetooth controller 410.
When receiving the above described Ready signal, the facsimile manager 401 uses the Serial Port Profile to perform initialization process between the facsimile manager 401 and the event control task 307 of the facsimile apparatus 201.
When the initialization process is completed, the facsimile manager 401 periodically sends the reception information acquirement command to the facsimile apparatus 201 via the Bluetooth control task 409 and the Bluetooth controller 410, and monitors whether or not the facsimile apparatus 201 has the received image. At S809, whether or not a response to this reception information acquirement command has been received is determined, and if the response has been received from the facsimile apparatus 201 via the Bluetooth control task 409 and the Bluetooth controller 410, information of existence/not existence of received image therein is stored in the Bluetooth control task 409 at S810.
At S811, as described in the latter half of
The “command return mode of the Bluetooth control task 409” will now be described.
The Bluetooth control task 308 is in the command return mode in the sate where no received image exists.
At S901 of the command return mode, the reception information acquirement command is sent to the event control task 307, and at S902, a response from the event control task 307 is received. When the response is received, reception information (image existed/not existed) stored in the response is stored in the Bluetooth control task 308 at S903.
At S904, whether or not the image exists in the reception information is determined, and if the image exists, the process proceeds to S906, where transition is made from the command return mode to the command through mode. If the image does not exist, the process waits to send the reception information acquirement command periodically at S905, and then the process returns to S901.
At S906, an Active return request is sent to the Bluetooth controller 309, and at S907, whether or not the command has been received is determined. This command is an operation instruction command from the facsimile manager 401 to the event control task 307 as described with
At S911, whether or not the response has been received is determined. This response is a response from the event control task 307 to the facsimile manager 401 as described with
At S914, the received response is sent to the Bluetooth controller 309, and the Bluetooth control task 308 determines whether or not the image exists in the stored reception information at S915, and if the image does not exist, the process proceeds to S916, where transition to the command return mode is made, and if the image exists, the process returns to S907, where the command through mode is continued.
At S916, the request for transition to the Park mode is sent to the Bluetooth controller 309, and transition to the command return mode is made.
At S917, transition to the command return mode is made if notification of Mode transition from the intelligent terminal 202 is received.
The Bluetooth control task 409 is in the command return mode in the state where no received image exists.
At S1001 of the command return mode, whether or not the reception information acquirement command has been facsimile manager 401 is determined, and if the command has been received, the process proceeds to S1002, and if it has not been received, the process proceeds to S1003.
At S1002, the reception information (image existed/not existed) stored in the Bluetooth control task 409 is sent to the facsimile manger 401 as a response.
At S1003, a procedure for return to Active (procedure for return to Active shown in
At S1004, transition to the Park mode led by the facsimile apparatus 201 is performed, and whether or not the Bluetooth control task 409 has received the Mode transition notification from the Bluetooth 410 is determined, and if the notification has not been received, the process proceeds to S1005, and if it has been received, the process proceeds to S1001, where transition to the command return mode is made.
At S1005, whether or not the command has been received is determined. This command is an operation instruction command from the facsimile manager 401 to the event control task 307 as described with
At S1010, whether or not the above described response is a response of the reception information acquirement command is determined, and if it is the response of the reception information acquirement command, the process proceeds to S1011, and if not, the process proceeds to S1012. The reception information (image existed/not existed) included in the response is stored in the Bluetooth control task 409 at S1011, and the response is sent to the facsimile manager 401 at S1012.
Timeout is reached when no effective data is available within a predetermined time period in the command through mode at S1013, and a request for transition to the Park mode is sent to the facsimile apparatus at S1014.
That is, the Bluetooth control task 409 of the intelligent terminal 202 is in the command return mode H at the time of stand-by that is in the Park mode, and though not shown, gives answers to the reception information acquirement command and the state information acquirement command sent from the facsimile manager 401 periodically.
Similarly, the Bluetooth control task 308 of the facsimile apparatus 201 is also in the command return mode J at the time of stand-by that is in the Park mode, and issues periodically the reception information command, and the state information acquirement command to the event control task 307 to monitor the state of the facsimile apparatus 201.
Then, when the user operates the operation unit of the intelligent terminal 202 to select a transmission service, the facsimile manager 401 sends to the Bluetooth control task 409 the transmission instruction command and a parameter in which the facsimile number of the opposite terminal 204 is designated.
Then, the Bluetooth control task 409, which receives the transmission instruction command and the parameter (facsimile number), returns the mode between the facsimile apparatus 201 and the intelligent terminal 202 to the Active mode (normal operation mode) in which data communication is possible to provide a transmission service.
That is, the Bluetooth control task 409 of the intelligent terminal 202 sends to the Bluetooth controller 410 a command of request for return to Active, and the Bluetooth controller 410 which receives the command of request for return to Active performs procedure for return to Active in conformity of the Bluetooth specification, with the Bluetooth controller 309, and returns the mode to the Active mode. And thereafter, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of mode change notification, and transition of the operation mode from command return modes H and J to command through modes I and K is made.
Furthermore, if the communication could not be recovered, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409 of the fact that the communication could not be recovered. At this time, the Bluetooth control tasks 308 and 409 keep the sate of the command return mode. Also, the Bluetooth control task 409 sends the answer: NG to the facsimile manager 401, and the facsimile manger 401 displays a message that transmission service cannot be performed, when receiving the answer: NG.
Also, if the communication could be recovered, the Bluetooth control task 409 of the intelligent terminal 202 sends directly to the event control task 307 of the facsimile apparatus 201 the transmission instruction command and the parameter (facsimile number) received from the facsimile manager 401.
Then, when the event control task 307 which receives the transmission instruction command and the parameter ensures that the facsimile apparatus 201 is not currently under communication, and is not full of reservations for transmission, it sends the response of “OK” to the facsimile manager 401 of the intelligent terminal 202. Furthermore, when the facsimile apparatus 201 is under communication or full of reservations for transmission, the response of “NG” is sent to the facsimile manager 401.
Then, when receiving the response of “OK” from the event control task 307, the facsimile manager 401 performs transmission image data transfer procedure G with a command interface similar to the cable I/F.
Then, when the transmission image data transfer procedure G is completed, the facsimile manager 401 issues to the facsimile apparatus 201 a transmission result acquirement command and a parameter in which the receipt number is designated to know the transmission result. Then, the event control task 307, which receives the transmission result acquirement command, searches the management information stored in the RAM 103, and checks the transmission result of the indicated receipt number. Thereafter, the event control task 307 sends to the facsimile manager 401 a response showing the completion of transmission together with the transmission result.
Furthermore, the facsimile manager 401 issues the transmission result acquirement command to the facsimile apparatus 201 until it is known from the response to the transmission result acquirement command that transmission is completed.
Then, when the Bluetooth control task 409 of the intelligent terminal 202 determines that transmission has been completed, the wireless communication line goes into the Park mode again.
That is, the Bluetooth control task 409 sends to the Bluetooth controller 410 the command of request for transition to the Park mode. The Bluetooth controller 410, which receives the command of request for transition to the Park mode, carries out procedure for transition to the Park mode, with the Bluetooth controller 309, and when the transition procedure is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode.
Then, when the Bluetooth control tasks 308 and 409 receive the notification of the transition to the Park mode, the operation modes become command return modes H and J again. That is, the command return modes H and J are continued until the user starts a service such as facsimile transmission, image reading process or printing process at the intelligent terminal 202, or the facsimile apparatus 201 receives image data. Then, in this command return mode, the command and response are exchanged only between the facsimile manager 401 and the Bluetooth control task 409, and between the Bluetooth control task 308 and the event control task 307, the command and response are not exchanged between the intelligent terminal 202 and the facsimile apparatus 201.
That is, as in the case of
Then, when the transmission image data transfer procedure G is completed, the facsimile manager 401 issues to the facsimile apparatus 201 the transmission result acquirement command and a parameter in which the receipt number is designated to know the transmission result. Then, the event control task 307, which receives the transmission result acquirement command and the above described parameter, searches the management information stored in the RAM 103, and acquires the transmission result of the indicated receipt number to send a response. The facsimile manager 401 of the intelligent terminal 202 is notified of this response. When determining from the response that it is in the redial stand-by state, the facsimile manager 401 displays the fact to notify the user thereof.
Also, when the Bluetooth control task 308 determines that it is in the redial stand-by state from the response sent to the facsimile manager 401 from the event control task 307, it sends to the Bluetooth controller 309 the command of request for transition to the Park mode. Then, the Bluetooth controller 309, which receives the command of request for transition to the Park mode, carries out procedure for transition to the Park mode with the Bluetooth controller 410, and when the procedure for transition is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode, and after the transition to the Park mode, transition of the operation mode to command return modes J and H is made.
Thereafter, the facsimile manager 401 sends periodically the transmission result acquirement command and the parameter to the Bluetooth control task 409, the Bluetooth task 409 sends to the facsimile manager 401 a response showing that it is in the state of redial standby.
Also, the Bluetooth control task 308 sends periodically the transmission result acquirement and the parameter to the event control task 307, and continues to store transmission results. Then, the event control task 307 sends to the Bluetooth control task 308 a response showing that it is in the state of redial standby.
And thereafter, when the transmission image that was in the state of redial standby is sent to the opposite normally, the event control task 307 gives back the completion of transmission as a response to the transmission result acquirement command and parameter from the Bluetooth control task 308. When the Bluetooth control task 308 determines from the response from the event control task 307 that the transmission process has been completed normally, it returns the mode with intelligent terminal 202 to the Active mode, and waits until the transmission result acquirement command and parameter from the facsimile manager 401 are received.
At this time, the Bluetooth control task 308 and the Bluetooth control task 409 recognize the return to the Active mode, and make transition to the command through node. When the Bluetooth control task 308 receives the transmission result acquirement command and parameter from the facsimile manager 401, it sends the transmission result acquirement command and parameter to the event control task 307. The event control task 307 receives the transmission result acquirement command and parameter, and if there exists a parameter showing the result of the above described transmission process that was in the state of redial standby, it gives back a response showing that the transmission process has been completed normally.
When the facsimile manager 401 recognizes from the response from the event control task 307 that the transmission process that was in the sate of redial standby has been completed normally, it displays the fact to notify the user thereof.
Also, when the Bluetooth control task 308 recognizes from the contents of the response sent from the event control task 307 that the transmission process that was in the sate of redial standby has been completed normally, it lets the mode with the intelligent terminal 202 make transition to the Park mode again. Then, the Bluetooth control task 308 and the Bluetooth control task 409 make transition to the command return mode.
Furthermore, as the above described operation during transfer redial process for the transmission image in
The case where a request for transition to the Park mode is made from the intelligent terminal 202 to the facsimile apparatus 201 after completion of the transfer redial process for the transmission image will now be described below, using
In
Then, when the transmission image data transfer procedure G is completed, the facsimile manager 401 issues to the facsimile apparatus 201 the transmission result acquirement command and a parameter in which a receipt number is designated to know the transmission result. The event control task 307, which receives the transmission result acquirement command and the above described parameter, searches the management information stored in the RAM 103, and acquires the transmission result of the designated number to send a response.
Then, when the Bluetooth control task 409 determines from the response from the event control task 307 that it is in the state of redial standby, it sends to the Bluetooth controller 410 the command of request for transition to the Park mode. Then, the Bluetooth controller 410, which receives the command of request for transition to the Park mode, carries out a procedure for transition to the Park mode with the Bluetooth controller 309, and when the procedure for transition is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode, and after the transition to the Park mode, transition of the operation mode to command return modes J and H is made.
Thereafter, the facsimile manager 401 sends periodically the transmission result acquirement command and the parameter to the Bluetooth control task 409, the Bluetooth control task 409 sends to the facsimile manager 401 a response showing that it is in the state of redial standby.
Also, the Bluetooth control task 308 sends periodically the transmission result acquirement command and the parameter to the event control task 307, and continues to store transmission results in the RAM 103. Then, the event control task 307 sends to the Bluetooth control task 308 a response showing that it is in the state of redial standby.
Furthermore, if the transmission image that was in the state of redial standby can be sent normally, the same process as described above is applied.
First, the intelligent terminal 202 sends a receipt number acquirement command to the facsimile apparatus 201 (step S1401). When the facsimile apparatus 201 receives the receipt number acquirement command, it sends to the intelligent terminal 202 the receipt number stored in the RAM 103 together with the answer of “OK” (step S1402).
Then, the intelligent terminal 202 sends a page information acquirement command to the facsimile apparatus 201, and sends to the facsimile apparatus 201 a parameter in which the main/sub scan resolution and the image size of image data to be sent is set (step S1403). The facsimile apparatus 201 determines based on the received parameter whether or not transmission is possible, and if transmission is possible, it sets each parameter to the management information of the RAM 103 and sends the answer of “OK” to the intelligent terminal 202 (step S1404). On the other hand, if transmission is not possible, the answer of “NG” is sent to the intelligent terminal 202.
Then, when the intelligent terminal 202 receives the answer of “OK” to the page information acquirement command, it sends an image data transfer instruction command, and image data and the image data size to the facsimile apparatus 201 (step S1405).
Then, the facsimile apparatus 201 receives image data by the image data transfer instruction command, accumulates the same in the image memory 104, and sends the answer of “OK” to the intelligent terminal 202 (step S1406). Furthermore, in this case, if there is no free space in the image memory 104, the answer of “NG” is sent to end the process.
Then, the intelligent terminal 202 sends image data of one page to the facsimile apparatus 201 during reception of the answer of “OK” to the image data transfer instruction command. Also, when the answer of “OK” is received to the image data transfer instruction command, transmission of the image data is stopped, and the abnormal end is displayed on the display unit.
Then, when a predetermined amount of transmission image data is accumulated in the image memory 104, the facsimile apparatus 201 originates a call to the destination facsimile number received with the transmission instruction command and performs facsimile transmission. Furthermore, each time facsimile transmission of one page is completed, the corresponding region of the image memory 104 is erased.
Then, whether or not image data transmission of one page has been completed is determined (step S1407), and if it has been completed, whether or not image data transmission of all pages has been completed is determined (step S1408), and if the answer thereto is negative (No), the process returns to S1403 to repeat the above described process, and if the answer thereto is positive (Yes), the process is ended.
That is, as in the case of
Then, when the transmission image data transfer procedure G is completed, the Bluetooth control task 409 sends to the Bluetooth controller 410 a command of request for transition to the Park mode, and the Bluetooth controller 410, which receives the command of request for transition to the Park mode, carries out a procedure for transition to the Park mode with the Bluetooth controller 309, and when the transition procedure is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth controller 308 and 409, respectively, of the transition to the Park mode, and the operation modes become command return modes J and H.
Then, when the operation modes become command return modes J and H, the Bluetooth control task 409 reads the transmission information (the transmission result acquirement command, the receipt number, etc.) stored in a RAM (not shown) of the intelligent terminal 202 and sends a response to the facsimile manager 401.
Also, the Bluetooth control task 308 of the facsimile apparatus 201 periodically sends to the event control task 307 the transmission result acquirement command and the receipt number of the transmission result that it wants to acquire. Then, the event control task 307 retrieves the transmission result of the corresponding receipt number from the management information stored in the RAM 103, and gives back the same as a response. The Bluetooth control task 308 continues this process until it is determined that the image data transmission process is completed.
Then, when the Bluetooth control task 308 receives from the event control task 307 a transmission completion response showing the completion of transmission of image data, the Bluetooth control task 308 sends to the Bluetooth controller 309 the command of request for return to Active to recover communication with the intelligent terminal 202.
The Bluetooth controller 309, which receives the request for return to Active, carries out the procedure for return to Active with the Bluetooth controller 410, and when the Active communication is returned, the Bluetooth controllers 309 and 410 give mode change notification to the Bluetooth control tasks 308 and 409, respectively, and make transition to command through modes K and I.
When transition to command through modes K and I is made in this way, the Bluetooth control task 409 sends directly to the Bluetooth controller 410 the transmission result acquirement command from the facsimile manager 401 and a parameter in which the receipt number of the transmission result that it wants to acquire is set, which are sent to the Bluetooth controller 309 via the Bluetooth controller 410, and are sent to the event control task 307 via the Bluetooth control task 308. Also, the event control task 307 sends the transmission result of the designated receipt number to the facsimile manager 401 as a response, and ends the process.
The process procedure during the above described transmission image transfer will now be described for the intelligent terminal 202 from which the image is transferred and the facsimile apparatus 201 to which the image is transferred, separately.
The Bluetooth control task 409 is in the command return mode H, when no received image exists, or in the state where the transmission instruction command from the facsimile manager 401 is not received.
Then, when the command from the facsimile manager 401 is received at step S1601, whether or not the received command is a transmission instruction command is determined at subsequent step S1602, and if the answer thereto is negative (No), the process proceeds to step S1603, where a needed response out of the information stored in the RAM is sent to the facsimile manager 401 in accordance with the received command, and the process returns to step S1601 to wait a command from the facsimile manager 401.
On the other hand, if the command from the facsimile manager 401 is a transmission instruction command, the answer at step S1602 is positive (Yes), and the process proceeds to step S1604, where the transmission instruction command and parameter received from the facsimile manager 401 are stored in the RAM, and thereafter the request for return to Active is sent to the Bluetooth controller 410. Then, at subsequent step S1615, whether or not mode transition notification could be received to perform return to Active is determined, and if the answer thereto is negative (No), a “NG” response is sent to the facsimile manager 401 and the process returns to step S1601 to execute the above described command return mode.
Also, when the answer at step S1615 is positive (Yes), namely if return to Active could be performed and mode transition notification was received, transition of the operation mode to the command through mode I, and the process proceeds to step S1605.
Then, at step S1605, the transmission instruction command and parameter from the facsimile manager 401, stored in the RAM, is sent to the Bluetooth controller 410, and the process proceeds to step S1606.
At step S1606, whether or not the command has been received is determined, and if the command has been received, the process proceeds to step S1607, where the command is sent to the Bluetooth controller 410, and thereafter the process returns to step S1606 to repeat the above described process. On the other hand, if the reception of the command has not occurred, the process proceeds to step S1610 to determine whether or not a response has been received from the Bluetooth controller 410. Then, when the answer thereto is negative (No), the process returns to step S1606 to repeat the above described process, while when the answer is positive (Yes), the process proceeds to step S1611, where the received response is sent to the facsimile manager 401, and at subsequent step S1612, whether or not the above described response is a response to the transmission result acquirement command is determined. Then, if the answer is negative (No), the process returns to step S1606 to repeat the above described process, while if the answer is positive (Yes), the response is stored in the RAM, and the process proceeds to step S1613.
Then, at step S1613, whether the transmission state is of redial standby or completion is determined based on the transmission result stored in the RAM, and if the answer thereto is negative (No), the process returns to step S1606, where the command through mode I is continued, while if the answer is positive (Yes), the process proceeds to step S1614, where the command of request for transition to the Park mode is sent to the Bluetooth controller 410, and thereafter the process returns to step S1601 to make transition to the command return mode H.
The Bluetooth control task 308 is in the command return mode J in the state where neither a received image nor transmission instruction request from the intelligent terminal 202 exists.
That is, at step S1701, whether or not the intelligent terminal 202 has been already notified of the transmission result is determined, and if the answer thereto is positive (Yes), the process proceeds to step S1705, while if the answer is negative (No), the process proceeds to step S1702, where the transmission information acquirement command is sent to the event control task 307, and at subsequent step S1703, the response to the transmission information acquirement command from the event control task 307 is stored in the RAM 103, and the contents of the response are analyzed to determine whether or not the transmission state has changed to completion of transmission is determined. Then, if the transmission state has not changed, the process proceeds to step S1705, where transition to the Active mode led by the intelligent terminal 202 is performed, and whether or not notification of the mode transition has been made is determined. Then, if the answer thereto is negative (No), the process waits for a predetermined time period to send a command such as the transmission information acquirement command and the reception information acquirement command periodically to the event control task 307, and thereafter the process the process returns to step S1701 to continue the command return mode J. On the other hand, if the answer is positive (Yes), the process proceeds to step S1707, where transition to the command return mode K is made.
Also, if the answer at step S1703 is positive (Yes) and thus the transmission state has changed, the process proceeds to step S1704, where the command of request for return to Active is sent to the Bluetooth controller 309, and connection to the intelligent terminal 202 is recovered, and the process proceeds to step S1707, where transition to the command return mode K is made.
That is, whether or not notification of the transition to the Park mode led by the intelligent terminal 202 has been made is determined at step S1707, and if the answer thereto is negative (No), the process proceeds to step S1708 to determine whether or not the command has been received, and if the command has been received, the process proceeds to step S1709 to send the command to the event control task 307, and thereafter the process returns to step S1707 to repeat the above described process. On the other hand, if the command has not been received, the process proceeds to step S1710, where whether or not a response from the event control task 307 has been received is determined. Then, when the answer thereto is negative (No), the process returns to step S1707 to repeat the above described process, while when the answer is positive (Yes), the process proceeds to subsequent step S1711. At step S1711, the received response is stored in the RAM 103 and is sent to the Bluetooth controller 309, and the process proceeds to step S1712.
At step S1712, the transmission result state stored in the RAM 103 is observed to whether or not the transmission is in the sate of redial standby, and when it is not in the sate of redial standby, the process returns to step S1707 to repeat the above described process. In this case, when it is completion of transmission, for example, the process of transition to the Park mode led by the intelligent terminal 202 is carried out and notification of the transition to the Park mode is given from the Bluetooth controller 309 to the Bluetooth control task 308, and therefore the answer at step S1707 is positive (Yes) and the process returns to step S1701, transition to the command return mode J is made for the operation mode.
Also, if the answer at step S1712 is positive (Yes), namely if it is determined that the transmission is in the state of redial standby, the process proceeds to step S1713, where the command of request for transition to the Park mode is sent to the Bluetooth controller 309 to perform transition to the Park mode led by the facsimile apparatus 201, and when the transition to the Park mode is confirmed, the process returns to step S1701, and transition to the command return mode J is made for the operation mode.
In the above described
The Bluetooth control task 308 is in the command return mode J in the state where neither a received image nor transmission instruction request from the intelligent terminal 202 exists.
That is, the reception information acquirement command is sent to the event control task 307 at step S3101, and when a response from the event control task 307 is received at step S3102, the received image information (information of existence/not existence of image) in the response is stored in the RAM 103 at subsequent step S3103, and then the process proceeds to step S3104.
At step S3104, transition to the Active mode led by the intelligent terminal 202 is performed, and whether or not notification of the mode transition has been made is determined. Then, if the answer thereto is negative (No), the process waits for a predetermined time period to send periodically a command such as the transmission information acquirement command and the reception information acquirement command to the event control task 307, and thereafter the process returns to step S3101 to continue the command return mode J. On the other hand, if the answer at step S3104 is positive (Yes), the process proceeds to step S3106, where transition to the command through mode K is made.
That is, whether or not notification of the transition to the Park mode led by the intelligent terminal 202 has been made is determined at step S3106, and if the answer thereto is negative (No), the process proceeds to step S3107 to determine the command has been received, and if the command has been received, the process proceeds to step S3108 to send the command to the event control task 307, and thereafter the process returns to step S3106 to repeat the above described process. On the other hand, if the command has not been received, the process proceeds to step S3109, where whether or not a response from the event control task 307 has been received is determined. Then, when the answer thereto is negative (No), the process returns to step S3106 to repeat the above described process, while when the answer is positive (Yes), the received response is stored in a RAM 103 and is sent to the Bluetooth controller 309 at subsequent step S3110, and the process returns to step S3106.
And thereafter, when due to the case where no transmission image exists and so on, transition to the Park mode led by the intelligent terminal 202 is performed, and consequently notification of the transition to the Park mode is made from the Bluetooth controller 309, the answer at step S3106 is positive (Yes), and the process returns to step S3101, where transition to the command return mode J is made for the operation mode.
Furthermore, the present invention should not be limited to the above described embodiment, and the wireless state at the above described command return mode is not limited to the Park mode, but may be a Standby mode in which the wireless link is opened, and other low power consumption modes such as Sniff Mode and Hold Mode in the Bluetooth specification.
Also, instead of facsimile apparatuses, other image formation apparatuses such as personal computers having image communication functions may be applied to the above described embodiment.
Also, for example, the image formation apparatus may comprise an electronic mail send/receive function in addition to the above described functions.
According to the above described embodiment, in the standby state, consumption of electric power and also occupation of the wireless channel, due to send/receive of a command to poll the state of the image formation apparatus such as a facsimile apparatus and a response thereto, is eliminated.
Also, since the state of low power consumption occurs automatically in the state where no service carries out, a wireless connection processing unit goes into the low power consumption state even without depending on an arrangement and command for transition to the low power consumption state, thus making it possible to reduce traffic of wireless communication, alleviate limitation for performing other services with other apparatuses through wireless communication, and reduce power consumption during the standby state.
The configuration of the facsimile apparatus in this embodiment is same as that of the first embodiment, and thus description thereof is omitted.
As shown in
The facsimile apparatus 201 is connected to the communication line 203, and can communicate with the opposite terminal 204. Also, the facsimile apparatus 201 can be wirelessly connected to respective intelligent terminals 202a to 202c. In this embodiment, since the wireless part is treated as Bluetooth, send/receive of image data and exchange of various kinds of data and programs can be performed with the intelligent terminals 202a to 202c if units for Bluetooth communication are included in the intelligent terminals 202a to 202c, respectively, or units for Bluetooth communication are connected to the intelligent terminals 202a to 202c. In addition, in this embodiment, a facsimile apparatus is employed as an image processing apparatus 201, but the image processing apparatus is not limited the facsimile apparatus, and it may be, for example, a multifunction apparatus comprising a scanner function and printer function, or it may be some other image processing apparatus such as an E-Mail terminal with a scanner or printer function added thereto, not causing departure from the nature of the present invention.
Also, the hierarchy of software for the facsimile apparatus 201 and the hierarchy of software for the intelligent terminals 202a to 202c are similar to the hierarchy of software described with
In addition, the process at the time of turning on the power of the intelligent terminals 202a to 202c, respectively, and the process at the time of turning on the power of the facsimile apparatus 201 are also similar to those of the embodiment described above, and thus description thereof is omitted.
Furthermore, in the following description, the process at the time of turning on the power of the intelligent terminals 202a to 202c is completed, and each of the intelligent terminals 202a to 202c is in the Park mode.
The Bluetooth control task 308 of the facsimile apparatus 201 is in the command return mode during standby, and issues periodically the state information acquirement command to the event control task 307 to monitor the state of the facsimile apparatus 201.
The event control task 307 checks whether or not the state of the facsimile apparatus has changed. In the facsimile apparatus 201, if the original is set in the reader unit 107, and the scan key is pressed, display is provided for selecting a transfer destination to which the scanned image is uploaded, and the user is asked to input a transfer destination. If the user selects, for example, PC (a) (intelligent terminal 202a) being a transfer destination, a flag indicating the existence of an image to be scanned and PC (a) as a destination to which the scanned image is uploaded are stored in the RAM 103. The event control task 307 checks this area to recognize that there exists an image to be transferred to PC (a), and gives back a response of existence of an original for scanning and a parameter to the state information acquirement command.
When receiving the response of existence of an original for scanning, the Bluetooth control task 308 recovers communication between the facsimile apparatus 201 and the intelligent terminal 202a to transfer the scanned image data to the intelligent terminal 202a. At this time, commands of request for return to Active, etc. from the intelligent terminals 202b and 202c are ignored.
The Bluetooth control task 308 sends a request for return to Active to the Bluetooth controller 309 to recover the communication. The Bluetooth controller 309, which receives the request for return to Active, communicates with the Bluetooth controller 410 of the intelligent terminal 202a, in accordance with the communication recovery procedure of Bluetooth. When the communication is recovered, the Bluetooth controller 309 gives mode change notification to the Bluetooth control task 308. The Bluetooth control task 308, which receives the mode change notification, makes transition from the command return mode to the command through mode when it determines from the contents of the notification that the communication has been recovered, while the Bluetooth task 308 maintains the state of the command return mode when it determines that the communication cannot be recovered.
Similarly, the Bluetooth controller 410 of the intelligent terminal 202a gives mode change notification to the Bluetooth control task 409. The Bluetooth control task 409, which makes transition from the command return mode to the command through mode when it determines from the contents of the notification that the communication has been recovered, while the Bluetooth control task 409 maintains the state of the command return mode and displays a message as such on the above described display unit of the intelligent terminal 202a when it determines that the communication cannot be recovered.
When the communication is recovered, each of the Bluetooth control tasks 308 and 409 goes into the command through mode, scan image data transfer process is carried out with a command interface same as the interface for connection with cables such as a parallel interface such as Centronics (standard interface defined in IEEE 1284, etc.). The scan image data transfer process will be described later.
When the scan image data transfer process is completed, the facsimile manager 401 issues the state information acquirement command to the facsimile apparatus 201. The event control task 307, which receives the state information acquirement command, makes a search as to whether or not a scan image exists with the flag, etc. stored in the RAM 103, and when the scan image exists, it gives back a response of “scan image existed”.
When the facsimile manager 401 determines from the response to the state information acquirement command that a scan image exists, it carries out the scan image data transfer process again, in accordance with the scan image data transfer process described later.
If no scan image exists, the event control task 307 that receives the state information acquirement command checks states associated with the facsimile apparatus 201 such as the state of the printer, the state of the scanner and the state of the memory, and gives back a response of normal state.
If the facsimile manager 401 determines from the response to the state information acquirement command that the state of error occurs, it displays a message showing the state of error on the above described display unit of the intelligent terminal 202a, and issues periodically the reception information acquirement command and the state information acquirement command to the event control task 307 until the state of error is corrected. On the other hand, when the facsimile manager 401 determines that the state of the facsimile apparatus 201 is normal, it issues periodically the state information acquirement command and the reception information acquirement command again until it makes transition to the Park mode being a power consumption mode.
The facsimile apparatus 201 makes again transition to the Park mode being a power consumption mode when it determines that the state is normal.
Then, the Bluetooth control task 308 of the facsimile apparatus 201 requests transition to the Park mode to the Bluetooth controller 309. The Bluetooth controller 309, which receives the request for transition to the Park mode carries out procedure of transfer to the Park mode with the Bluetooth controller 410 in accordance with the specification of Bluetooth.
When the transition procedure is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode.
When receiving the notification of the transition to the Park mode, the Bluetooth control tasks 308 and 409 go into command return modes, respectively.
Then, again, the command return mode is maintained until the user starts a service such as facsimile transmission, scan instruction or print in the intelligent terminals 202a to 202c, or scan operation and facsimile reception occur in the facsimile apparatus 201.
In the facsimile apparatus 201, when an original to be scanned is set on the reader unit 107, and the scan key is pressed, a flag showing that an original for scanning exists is set. Then, display is provided on the display unit of the operation unit 108 for selecting a transfer destination to which data is uploaded and the user is asked to select the transfer destination. When the transfer destination is selected, the transfer destination is stored in a predetermined area of the RAM 103 as in the case of the above described flag.
If it is known that an original for scanning exists from the above described area, a response of “original for scanning existed” is given back to the state information acquirement command from the intelligent terminal 202a.
Then, a scan instruction command is sent from the intelligent terminal 202a, and the facsimile apparatus 201 that receives this command gives back the answer of “OK” when the reader unit 107 is operable, and gives back the answer of “NG” when the reader unit 107 is not operable. When the answer to the scan instruction command is “OK”, the intelligent terminal 202a sends a scan setup instruction command, and subsequently a setup parameter such as read main/sub scan resolution. The facsimile apparatus 201 that receives those sends the answer of “OK” if read control in accordance with the parameter is possible, while it sends the answer of “NG” if read control in accordance with the parameter is impossible.
If the answer of “OK” is sent, the facsimile apparatus 201 reads the original with the reader unit 107, accumulates encoded data in the image memory (DRAM) 104, and transfers image data of predetermined size from the image memory (DRAM) 104 to the intelligent terminal 202 together with the answer of “OK” if a request for transfer of image data is made from the intelligent terminal 202a. If meanwhile, an interruption by a stop key (not shown) from the operation unit 108 or an error of the read system such as an original jam occurs, the facsimile apparatus 201 sends the answer of “NG”. Then, the facsimile apparatus 201 transfers original read image data of one page, examines whether or not a next original for reading exists after transfer of one page is completed, notifies the intelligent terminal 202a thereof, and waits for the scan setup instruction command from the intelligent terminal 202a if a next original for reading exists. On the other hand, if a next original for reading does not exist, the process is ended.
In
On the other hand, if the Piconet has not been eliminated, the process proceeds to step S2102, where whether or not a request for transition to Active is made is determined by the mode change notification from the Bluetooth controller 309. If the request for return to Active is made, the process proceeds to step S2110, where transition to the command through mode is made, while if the request for return to Active is not made, the process proceeds to step S2103.
The state information acquirement command is sent to the event control task 307 at step S2103, and a response is received at step S2104.
When the response is received, the state information included in the response is stored in the Bluetooth control task 308 at step S2105.
Whether or not a request for scanning is made is determined from the stored state information at step S2106, and if the request for scanning is not made, the process proceeds to S2107, where the process waits to send the information acquirement command periodically, and thereafter the process returns to step S2101. On the other hand, if the request for scanning is made, the process proceeds to step S2108, where the intelligent terminal (for example, intelligent terminal 202a) that is a transfer destination is read from the stored state information, and at step S2109, in order to make a request for return to Active to the intelligent terminal that is a transfer destination, such a request for return to Active is sent to the Bluetooth controller 309. Then, the process proceeds to step S2110, where transition is made from the command return mode to the command through mode.
At step S2110, whether or not a command has been received is determined, and the process proceeds to step S2116, where the command is sent to the event control task 307 if the command has been received, and the process proceeds to step S2111 if the command has not been received.
Whether or not an image has been received is determined at step S2111, and the process proceeds to step S2117, where the image is sent to the Bluetooth controller 309 if the image has been received, and the process proceeds to step S2112 if the image has not been received.
Whether or not a response has been received is determined at step S2112, and the process returns to step S2110 id the response has not been received, while the process proceeds to step S2113 if the response has been received.
When the response is received, the state information included in the response is stored in the Bluetooth control task 308 at step S2114. Then, the response received from the event control task 307 is sent to the Bluetooth controller 309 at step S2115.
Then, whether or not upload of the scanned image has been completed is determined at step S2118, and the process returns to step S2110 if it has not been completed yet, and the process proceeds to step S2119 if it has been completed.
At step S2119, a request for transition to the Park mode is sent to the Bluetooth controller 309 to make transition to the Park mode, and transition to the command return mode is made, and the process returns to step S2101.
In
Whether or not a scan key (not shown) existing in the operation unit 108 has been pressed is determined at step S2202, and the process returns to step S2201 if it has not been pressed, and the process proceeds to step S2203 if it has been pressed.
At step S2203, whether or not intelligent terminals connected with Bluetooth exist is determined from the connection destination list stored in the RAM 103. If no connection destinations exist, the process proceeds to step S2204, where display of “transfer impossible” is provided on the LCD display unit (not shown) of the operation unit 108, and this image scan process is ended. Furthermore, display showing that a connection destination does not exist is not limited to display by the LCD display unit, but may be the light of an error lamp, for example.
If connection destinations exist at step S2203, the process proceeds to step S2205, where whether or not there exists only one connection destination is determined. If there exists a plurality of connection destinations, the process proceeds to step S2207, where the current connection destinations are displayed on the LCD display unit of the operation unit 108, and the user is prompted to select which intelligent terminal the scanned image is to be sent to.
Then, whether or not the intelligent terminal being a transfer destination has been selected with the operation in the operation unit 108 is checked at step S2208, and the process returns to step S2207 if the intelligent terminal being a transfer destination has not been selected, while if the intelligent terminal being a transfer destination has been selected, the process proceeds to step S2209, where the selected intelligent terminal being a transfer destination is registered being a transfer destination.
Then, the state information acquirement command from the Bluetooth control task 308 is waited at step S2210, and when the state information acquirement command is received, the process proceeds to step S2211, where “scan request existed” and the information of the intelligent terminal being a transfer destination are given back to the Bluetooth control task 308 as a response to the state information acquirement command, and the above described FAX scan service process (scan image data transfer process) is carried out.
If there exists only one connection destination at the above described step S2205, the process proceeds to step S2206, where the intelligent terminal that the current transfer destination is registered being a transfer destination without carrying out processes such as display of a connection destination, and the process proceeds to step S2210, where the aforesaid process is carried out.
In
The state information stored in the Bluetooth control task 409 is sent to the facsimile manager 401 as a response at step S2302.
At step S2303, transition to the Active mode led by the facsimile apparatus 201 is performed, and whether or not mode transition notification has been received is determined, and if it has not been received, the process returns to step S2301, and if it has been received, the process proceeds to step S2304, where transition to the command through mode is made.
At step S2304, transition to the Park mode led by the facsimile apparatus 201 is performed, and whether or not mode transition notification has been received is determined, and if it has not been received, the process proceeds to step S2305, and if it has been received, the process returns to step S2301, where transition to the command return mode is made.
At step S2305, whether or not a command has been received is determined, and if it has been received, the process proceeds to step S2306, where the command is sent to the Bluetooth controller 410, and if it has not been received, the process proceeds to step S2307.
At step S2307, whether or not an image has been received is determined, and if it has been received, the process proceeds to step S2308, where the image is sent to the facsimile manager 401, and if it has not been received, the process proceeds to step S2309.
At step S2309, whether or not a response has been received is determined, and if it has been received, the process proceeds to step S2310, and if it has not been received, the process returns to step S2304.
At step S2310, whether or not the response is a response to the state information acquirement command is determined, and if it is a response to the state information acquirement command, the process proceeds to step S2311, and if it is not a response to the state information acquirement command, the process proceeds to step S2312.
At step S2311, the state information included in the response is stored in the Bluetooth control task 409, and the process proceeds to step S2312.
At step S2312, the response is sent to the facsimile manager 401.
The Bluetooth control task 308 of the facsimile apparatus 201 is in the command return mode during standby, and issues periodically the state information acquirement command and the reception information acquirement command to the event control task 307 to monitor the state of the facsimile apparatus 201. The event control task 307, which receives the state information acquirement command, checks states associated with the facsimile apparatus 201 such as the state of the printer, the state of the scanner and the state of the memory, and sends back a response as such. Also, for the reception information acquirement command issued by the Bluetooth control task 308, the event control task 307 makes a search as to whether the received image exists in the image management record stored in the RAM 103, and sends a response as such.
Similarly, the facsimile manager 401 of the intelligent terminal 202b is in the command return mode during standby, and issues periodically the state information acquirement command and the reception information acquirement command to the Bluetooth control task 409. The Bluetooth control task 409, which receives the state information acquirement command, sends back the stored state associated with the facsimile apparatus 201 as a response. For the reception information acquirement command, a search is made as to whether the received image exists in the stored image management record, and sends back a response as such.
By the way, in the case where reception of beacons becomes impossible and the Park mode cannot be maintained because the power of the intelligent terminal 202b is turned off, it moves to a dead spot outside a space to which the radio wave reaches, and so on, the Bluetooth controller 309 of the facsimile apparatus 201 sends mode change notification of elimination of Piconet to the Bluetooth control task 308.
The Bluetooth control task 308 receives the notification, and deletes the intelligent terminal 202b from the connection destination list in the RAM 103. At this time, if other connection destination intelligent terminals (the intelligent terminal 202a or 202c in this embodiment), the state information acquirement command and the reception information acquirement command are sent periodically to the event control task 307 as ever. On the other hand, in the case where the intelligent terminal 202b is deleted from the connection destination list, whereby connection destinations no longer exist, the Bluetooth control task 308 stops sending the state information acquirement command and the reception information acquirement command.
Also, the Bluetooth controller 410 in the intelligent terminal sends mode change notification of elimination of Piconet to the Bluetooth control task 409, and thereafter stops sending the state information acquirement command and the reception information acquirement command. However, in the case where Piconet is eliminated because the power of the intelligent terminal is turned off, this process is not (cannot be) carried out.
The present invention should not be limited to the above described embodiment, and the wireless state at the above described command return mode is not limited to the Park mode, but may be a standby state in which the wireless link is opened, and other modes such as Sniff Mode and Hold Mode in the Bluetooth.
The above described each embodiment represents an example in which the Park mode is maintained when no command is exchanged between the facsimile apparatus and the intelligent terminal, but in this case, an example in which the Standby mode is maintained when no command is exchanged between the facsimile apparatus and the intelligent terminal will be described. In the Standby mode referred herein, since synchronization of clock is not retained between the master and the slave, Piconet can no longer be retained. This embodiment will be described in detail below, based on the drawings.
The image processing apparatus constituting the image processing system of this embodiment, the configuration of the image processing system, and the hierarchy of control software thereof are similar to those of the above described embodiment, and thus description thereof is omitted.
The process after the intelligent terminal 202a is turned on until process for connecting it to the facsimile apparatus 201 is carried out is same as that in
Also, the Bluetooth controller 410, which receives the Detach message, makes transition to the Standby mode, and notifies the Bluetooth control task 409 of the transition to the Standby mode.
When the Bluetooth control tasks 308 and 409 are notified of the transition to the Standby mode, they make transition to the command return mode, respectively.
The Bluetooth control task 308 of the facsimile apparatus 201 is in the command return mode during standby, and issues periodically the state information acquirement command to the event control task 307 to monitor the state of the facsimile apparatus 201.
The event control task 307 checks whether or not the state of the facsimile apparatus has changed. In the facsimile apparatus 201, if the original is set in the reader unit 107, and the scan key is pressed, display is provided for selecting a transfer destination to which the scanned image is uploaded, and the user is asked to input a transfer destination. If the user selects, for example, PC (a) (intelligent terminal 202a) as a transfer destination, a flag indicating the existence of an image to be scanned and PC (a) as a destination to which the scanned image is uploaded are stored in the RAM 103. The event control task 307 checks this area to recognize that there exists an image to be transferred to PC (a), and gives back a response of “original for scanning existed” to the state information acquirement command as a parameter.
When receiving the response of existence of an original for scanning, the Bluetooth control task 308 recovers communication between the facsimile apparatus 201 and the intelligent terminal 202a to transfer the reception image data to the intelligent terminal 202a. At this time, commands from the intelligent terminals 202b and 202c are ignored.
An Inquiry sending request is sent to the Bluetooth controller 309 to recover communication. The Bluetooth controller 309, which receives the Inquiry sending request, carries out an Inquiry procedure in accordance with the connection procedure of Bluetooth, and notifies the Bluetooth control task 308 of the result thereof. When the Bluetooth control task 308 receives the “Inquiry Result”, it determines from the contents thereof whether or not connection to the intelligent terminal 202a is possible, and designates an address of the intelligent terminal 202a and makes a connection request to the Bluetooth controller 309 when the connection is possible.
When the Bluetooth controller 309 receives the connection request, it performs establishment of a connection using “Serial Port Profile” for the Bluetooth controller 410 of the intelligent terminal 202a, based on the specification of Bluetooth. Then, when the connection is established, the Bluetooth controller 309 notifies the Bluetooth control task 308 of the result thereof.
When the Bluetooth control task 308 detects from the connection result that the connection could be established, it makes transition to the command through mode.
The Bluetooth controller 410 of the intelligent terminal 202a also notifies the Bluetooth control task 409 of the connection result. When the Bluetooth control task 409 ensures from the connection result that the connection has been established, it makes transition to the command through mode.
When the communication is recovered, and each of Bluetooth control tasks 308 and 409 goes into the command through mode, the scan data transfer process is carried out as described above.
When the scan data transfer process is completed and it is determined that the state of the facsimile apparatus 201 is normal, the facsimile apparatus 201 makes transition to the Standby mode as described with
The control of transfer commands and data between the facsimile apparatus 201 and the intelligent terminal 202a in the scan image data transfer process is similar to the process of transfer control described above, and thus description thereof is omitted.
Also, the process at the time when the power of the facsimile apparatus 201 is turned on is similar to that of the above described embodiment, and thus description thereof is omitted.
It is identical to
At step S2801, whether or not notification of the reception of “Inquiry” is given from the Bluetooth controller 309 is determined. If the Bluetooth controller 309 has received the “Inquiry”, the process proceeds to step S2807, where connection procedure is carried out with the opposite sending the “Inquiry” based on the specification of Bluetooth. Then, whether or not the opposite sending the “Inquiry” is included in the connection destination list is determined at step S2808, and if it is not included in the connection destination list, the process proceeds to step S2809, where the opposite sending the “Inquiry” is added in the connection destination list, and the process moves to the process of the command through mode described later. If it is included in the connection destination list, the process skips step S2809 and moves to the process of the command thorough mode described later. On the other hand, if notification of the reception of the “Inquiry” is not given from the Bluetooth controller 309 at step S2801, the process proceeds to step S2802.
At step S2802, the state information acquirement command is sent to the event control task 307, and at step S2803, a response is received.
When the response is received, the state information included in the response is stored in the Bluetooth control task 308 at step S2804.
At step S2805, whether or not a scan request is made is determined from the stored state information, and if the scan request is not made, the process proceeds to step S2806, where the process waits to send the information acquirement command periodically, and thereafter returns to step S2801.
On the other hand, if the scan request is made, the process proceeds to step S2810, where the intelligent terminal being a transfer destination (for example, intelligent terminal 202a) is read from the stored state information, and at step S2811, the Inquiry sending request is sent to the Bluetooth controller 309 to send the “Inquiry” to the intelligent terminal being the transfer destination. Then, at step S2812, whether or not connection has been established is determined. If the connection is established, the process proceeds to step S2813, where transition is made form the command return mode to the command through mode.
If notification of the establishment of the connection is not received at step S2812, and the connection is unsuccessful, the process proceeds to step S2822, where notification of the unsuccessful connection is made, and the intelligent terminal being the transfer destination is deleted from the connection destination list, and the process returns to step S2801.
The process steps S2813 to S2821 in the command through mode are same as the above described steps S2110 to S2118 of
At step S2821, whether or not upload of the scanned image has been completed is determined as in the case of step S2118, and if the upload has not been completed yet, the process returns to step S2813, and if it has been completed, the process proceeds to step S2824.
At step S2824, a request for transition to the Standby mode is sent to the Bluetooth controller 309 to make transition to the Standby mode, and transition to the command return mode is made, and the process returns to step S2801.
The procedure of scan process carried by the CPU 101 of the facsimile apparatus 201 when the image is scanned in response to the scan request from the facsimile apparatus 201 is same as the above described procedure in
In
At step S2902, the state information stored in the Bluetooth control task 409 is sent to the facsimile manager 401 as a response.
Whether or not the Bluetooth controller 410 has received the “Inquiry” is determined at step S2903, and if it has not received the “Inquiry”, the process returns to step S2901, and if it has received the “Inquiry” the process proceeds to step S2904, where the connection procedure for establishment of connection is carried out based on the specification of Bluetooth, and transition to the command through mode is made.
At step S2905, whether or not the Bluetooth controller 410 has received from the facsimile apparatus 201 a Detach command providing instructions to make transition to the Standby mode is determined, and if it has not received the command, the process proceeds to step S2906, and if it has received the command, the process returns to step S2901, where transition to the command return mode is made.
The subsequent step S2906 and the steps thereafter are same as the above described steps S2305 to S2312 in
As described above, according to the above described second and third embodiments, it is made possible to select which information processing apparatus the scan image is transferred to, when the scan image is transferred to the information processing apparatus under the situation in which a plurality of information processing apparatuses is wirelessly connected to the image processing apparatus.
Also, when the situation occurs in which there is one information processing apparatus that is wirelessly connected to the image processing apparatus, this situation is detected, and the scan image is transferred to this information processing apparatus automatically, thus making it possible to transfer the scan image immediately without performing needless operations.
In addition, when the situation occurs in which there is no information processing apparatus that is wirelessly connected to the image processing apparatus, this situation is detected, and the fact that no information processing apparatus to which the scan image is transferred exists is displayed before the image scanned, thus making it possible to eliminate needless scanning by the user.
Also, after instructions for scanning of the image and the selection of the information processing apparatus are determined, the connection mode in Piconet of Bluetooth with the information processing apparatus is returned from the power consumption mode and the state where Piconet is eliminated to the state where communication is possible, thus making it possible to perform transfer of the scan image to the designated destination information processing apparatus without delay, even when the connection to the information processing apparatus is in the power consumption mode and in the state where Piconet is eliminated. Also, the connection to the information processing apparatus can go into the power consumption mode and the state where Piconet is eliminated, thus making it possible to reduce wireless traffic and achieve low power consumption.
In addition, in Piconet with a plurality of information processing apparatuses, if the Park mode is retained with at least one information processing apparatus, exchange of commands with a pseudo information processing apparatus in the image processing apparatus is continued, but if Piconet with all information processing apparatuses is eliminated, the exchange of commands with the above described pseudo information processing apparatus in the image processing apparatus is stopped, thus making it possible to prevent useless processes and alleviate loads on the image processing apparatus.
In this embodiment, various kinds of states are displayed in the facsimile apparatus 201 to enhance ease of use of the facsimile apparatus 201 described in the above described embodiments. Furthermore, description of operations similar to those in the above described respective embodiments is omitted, and different operations will be described below.
The operation unit 108 is constituted by various kinds of keys, an LED, an LCD, etc., by which the operator performs various kinds of input operations, and display of operation states of the image processing apparatus, etc. are performed.
That is, the operation unit 108 has an LCD 3201 for displaying time and dial numbers, the mode of the facsimile apparatus 201 (standby, Park, Active) in Bluetooth Piconet, etc., a ten key 3202 for performing input of dial numbers, etc., a “start key” 3203 for starting transmission and starting copy, and performing forced printout, a “stop key” 3204 for forced end of communication, etc., a “registration key” 3205 for various kinds of registrations, a “one touch key” 3206 for use also in data registration in the case of the registration mode, and a “memory lamp” 3207 that lights up when images exist in the image memory.
Furthermore, for example, since communication of Bluetooth is in the Active mode when the facsimile apparatus 201 goes into the command through mode, the above described LCD 3201 displays Active mode, and switches the display of mode from the display of Active mode to the display of Park mode when the mode is changed from the command through mode to the command return mode.
In the above described embodiment, when the facsimile apparatus is in the state of standby (the state where there exists no original in the reader unit, and none of send/receive, scanning, printing and input of dials and registration information are being performed), the start key 3203 operates as a forced printout key. If the start key 3203 is entered in the state where the memory lamp 3207 lights up, namely the image is stored in the image memory at standby, the image in the image memory can be printed out.
In
Then, the variable for storing existence/not existence of received images, which is managed by the Bluetooth control task 308, is set at “not existence of received images”. In addition, since the facsimile apparatus 201 does not participate in Piconet of Bluetooth yet when the power is turned on, a Bluetooth control unit 115 of the facsimile apparatus is in the Standby mode. Therefore, Standby mode is displayed on the LCD 3201 of the operation unit 108.
The above described processes are performed, and startup of the intelligent terminal 202 is waited.
As described in
Thereafter, processes of S907 to S915 are carried out as in the case of
According to this embodiment, since the mode of the radio unit of the facsimile apparatus is displayed, the user can easily understand reasons why the wireless channel cannot be used, and so on.
Also, if the image to be transferred to the intelligent terminal remains in the facsimile apparatus for some reason, this situation can be displayed in an easy-to-understand manner.
In addition, if it is found by display that the image to be transferred to the intelligent terminal remains in the facsimile apparatus for some reason, this image can be printed out forcefully.
Another embodiment will be described below.
The configurations of the facsimile apparatus and the intelligent terminal, and the configuration of software are similar to those in the first embodiment.
When the power of the intelligent terminal 202 is turned on, the Bluetooth compatible facsimile manager 401 is started up to carry out process for connection to the facsimile apparatus 201.
That is, the Bluetooth control task 409 sends an Inquiry sending request to the Bluetooth controller 410 in order to ensure that the facsimile apparatus 201 being a connection destination is ready for communication. At this time, “Class of Device” information in the Inquiry command is sent as a “serial communication terminal”.
When receiving the Inquiry sending request, the Bluetooth controller 410 carries out “Inquiry” procedure in accordance with the connection procedure of Bluetooth, and notifies the Bluetooth control task 409 of the result (“Inquiry Result”). When the Bluetooth control task 409 receives the “Inquiry Result”, it determines based on the contents thereof whether or not connection to the facsimile apparatus 201 is possible, and if the connection is possible, it designates the address of the facsimile apparatus 201 and makes a connection request to the Bluetooth controller 410, while if connection is not successful, or the facsimile apparatus being a connection destination is not found from the contents of the “Inquiry Result”, it displays a message as such on the display unit (not shown) of the intelligent terminal 202.
When the Bluetooth controller 410 receives the connection request, it establishes connection using “Serial Port Profile” to the Bluetooth controller 309 of the facsimile apparatus 201, based on the specification of Bluetooth. Then, when the connection is established, the Bluetooth controller 410 notifies the Bluetooth control task 409 of the result thereof.
When the Bluetooth control task 409 detects from the connection result that the connection to the facsimile apparatus 201 could be established, it sends a ready signal to the facsimile manager 401, passes directly to the Bluetooth controller 410 the command from the facsimile manager 401, and makes transition in state to the command through mode.
Also, when the Bluetooth control task 409 receives from the connection result a message showing failure in establishment of connection, it displays the message on the above described display unit of the intelligent terminal 202.
The Bluetooth controller 309 of the facsimile apparatus 201 notifies the Bluetooth control task 308 of the result of the procedure of establishment of the connection to the intelligent terminal 202. When the Bluetooth control task 308 ensures from the result of the connection establishment procedure that the connection has been established, it enters the command through mode, and waits for a command from the intelligent terminal 202 to pass the command from the intelligent terminal 202 directly to the event control task 307. On the other hand, in case of failure in connection, the Bluetooth control task 308 is in the state of standby until the connection is established.
When the facsimile manager 401 receives the Ready signal from the Bluetooth control task 409, it sends to the Bluetooth control task 409 a command for transferring to the facsimile apparatus 201 data such as date information possessed by the intelligent terminal 202 and names registered in the facsimile manager 401.
The Bluetooth control task 409 transfers the received command directly to the Bluetooth controller 410, and the Bluetooth controller 410 uses the “serial Port profile” to transfer the command to the facsimile apparatus 201.
The Bluetooth controller 309 of the facsimile apparatus 201 sends to the Bluetooth control task 308 the command sent from the intelligent terminal 202, and the Bluetooth control task 308 passes the command directly to the event control task 307.
The event control task 307 analyzes the received command, and sends the result thereof to the Bluetooth control task 308.
When the initialization process is completed in this way, the Bluetooth control task 409 sends to the facsimile apparatus 201 the state information acquirement command for acquiring the sate of the facsimile apparatus 201. When receiving this state information acquirement command, the event control task 307 checks whether or not the received image exists, and states associated with the facsimile apparatus 201 such as the state of the printer, the state of the scanner and the state of the memory, and gives back information corresponding to the check result to the intelligent terminal 202 as a response. When the Bluetooth control task 409 receives the response to the state information acquirement command, it stores this state information, for example, in a RAM (not shown).
When storing the state information, the Bluetooth control task 409 requests transition to the Park mode to the Bluetooth controller 410 in order to enter the Park mode being one of low power consumption modes. The Bluetooth controller 410 that receives the request for transition to the Park mode carries out procedure for transition to the Park mode, with the Bluetooth controller 309, based on the specification of Bluetooth. When the transition procedure is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode. When receiving the notification of the transition to the Park mode, the Bluetooth control tasks 308 and 409 go into the command return mode, respectively.
Furthermore, in this embodiment, the Park mode is selected as a low power consumption mode, but being not limited thereto, any one of other low power consumption modes, namely Sniff mode or Hold mode and modes in which Piconet is released may be selected.
Going into the command return mode, the Bluetooth control task 409 of the intelligent terminal 202 performs processes similar to those of the event control task 307 of the facsimile apparatus 201 when connected with cables such as serial interfaces such as RS40132C, and parallel interfaces such as Centronics (standard interface defined in IEEE 1284, etc.). That is, the Bluetooth control task 409 gives back a response to the state acquirement command issued periodically from the facsimile manager 401, based on the state information stored in the above described RAM of the intelligent terminal 202.
The Bluetooth control task 308 of the facsimile apparatus 201 performs operations similar to those of the facsimile manger 401 of the intelligent terminal 202 when connected with cables described above. The Bluetooth control task 308 of the facsimile apparatus 201 issues periodically the state information acquirement command to the event control task 307 to monitor at all times the state of the facsimile apparatus 201, and whether or not the image has been received from other facsimile apparatuses through the communication line 203.
In
The Bluetooth control task 308 sends to the Bluetooth controller 309 a request for return to Active to recover the communication. The Bluetooth controller 309, which receives the request for return to Active, communicates with the Bluetooth controller 410 of the intelligent terminal 202 in accordance with the communication recovery procedure of Bluetooth. When the communication is recovered, the Bluetooth controller 309 gives mode change notification to the Bluetooth control task 308. The Bluetooth control task 308, which receives the mode change notification, makes transition from the command return mode to the command through mode when it determines from the contents of the notification that the communication has been recovered, while it retains the state of the command return mode as ever when it determines that the communication cannot be recovered.
Similarly, the Bluetooth controller 410 of the intelligent terminal 202 gives mode change notification to the Bluetooth control task 409. The Bluetooth control task 409, which receives the mode change notification, makes transition from the command return mode to the command through mode when it determines from the contents of the notification that the communication has been recovered, while it retains the state of the command return mode as ever when it determines that the communication cannot be recovered. When the Bluetooth control task 409 that makes transition to the command through mode receives the state information acquirement command from the facsimile manager 401, it passes the state information acquirement command to the Bluetooth controller 410 to send the same to the facsimile apparatus 201. The event control task 307 of the facsimile apparatus 201 that receives the state information acquirement command searches the image management record stored in the RAM 103 as to whether or not the received image exists, and performs detection of the usage situation and abnormalities for the facsimile apparatus 201 to send back state information such as existence/not existence of received images, possibility/impossibility of reception, possibility/impossibility of transmission and possibility/impossibility of scan to the Bluetooth control task 409 as a response to the state information acquirement command. The Bluetooth control task 409, which receives the response of the state information acquirement command, stores the received state information in a temporary area (for example, a work area of the above described RAM). The Bluetooth control task 409, which receives the state information, requests transition to the Park mode to the Bluetooth controller 410 in order to make transition to the Park mode being a low power consumption mode, and the Bluetooth controller 410, which receives the request for transition to the Park mode, carries out procedure for transition to the Park mode with the Bluetooth controller 309. The Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode. When the Bluetooth control task 308 receives the notification of the transition to the Park mode, it makes transition to the command return mode, sends again the reception information acquirement command periodically to the event control task 307, and monitors the state of the facsimile apparatus 201.
Also, the Bluetooth controller 410, which receives the notification of the transition to the Park mode, writes in a normal area the state information stored in the above described temporary area, and updates the state information of the facsimile apparatus 201.
In shown example, the state change is that of reception of the image, and the received image part of the state information stored by the Bluetooth control task 409 is updated from “image not existed” to “image existed” at this time. The received image part of the response to the state information acquirement command from the facsimile manager 401 thereafter is “image existed”.
As described using
When the Bluetooth control task 409 receives the reception upload command, it determines from the stored state information of the facsimile apparatus 201 whether or not reception upload is possible. If the received image part of the state information is “image not existed”, the Bluetooth control task 409 determines that reception upload is not possible, and sends a response of “NG” directly to the facsimile manager 401 without sending a command to the facsimile apparatus 201. On the other hand, if the received image part of the state information is “image existed”, the Bluetooth control task 409 determines that reception upload is possible, and requests return to the Active mode enabling communication from the Park mode being a low power consumption mode, to the Bluetooth controller 410 so that communication with the facsimile apparatus 201 can be performed.
The Bluetooth controller 410, which receives the request for return to the Active mode, carries out communication recovery procedure of Bluetooth, with the Bluetooth controller 309. When the communication is recovered, the Bluetooth controller 309 gives mode change notification to the Bluetooth control task 308, and the Bluetooth control task 308 that receives the mode change notification makes transition to the command through mode. Also, the Bluetooth controller 410 gives mode change notification to the Bluetooth control task 409, and the Bluetooth control task 409 that receives the mode change notification makes transition to the command through mode, and sends to the facsimile apparatus 201 the reception upload command previously received from the facsimile manager 401.
The event control task 307, which receives the reception upload command, sends back a response of “OK” to the intelligent terminal 202 because the received image exists.
When each of the Bluetooth control tasks 308 and 409 goes into the command through mode in this way, the reception image data transfer procedure is carried out using the “Serial Port Profile” based on the specification of Bluetooth, by the command interface same as that when connected with cables such as serial interfaces such as RS40132C, and parallel interfaces such as Centronics (standard interface defined in IEEE 1284, etc.) Furthermore, control of transfer of commands and data between the facsimile apparatus 201 and the intelligent terminal 202 in the reception image data transfer procedure is similar to that in
When the reception image data transfer procedure is completed, the Bluetooth control task 409 sends the state information acquirement command to the facsimile apparatus 201 for synchronization with the operation sate of the facsimile apparatus 201. The event control task 307 that receives the state information acquirement command checks state information such as existence/not existence of received image, and possibility/impossibility of transmission/reception/scan, and sends the same to the intelligent terminal 202 as a response.
The Bluetooth control task 409 stores the received state information. The Bluetooth control task 409 that receives the state information determines that a series of processes have been completed, and requests transition to the Park mode being a low power consumption mode to the Bluetooth controller 410 to return to the stationary state. The Bluetooth controller 410 that receives the request for transition to the Park mode carries out procedure for transition to the Park mode with the Bluetooth controller 309, in accordance with the specification of Bluetooth.
When the transition procedure is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode.
When the Bluetooth control tasks 308 and 409 receive the notification of the transition to the Park mode, each of them goes into the command return mode.
In the shown example, the facsimile apparatus 201 is in the sate where transmission is possible, and the transmission possible/impossible part of the state information stored by the Bluetooth control task 409 of the intelligent terminal 202 through the process described using
When the Bluetooth control task 409 receives the transmission instruction command being an operation instruction request, it determines from the stored state information whether or not transmission can be performed. When the transmission possible/impossible part of the state information is “impossible”, the Bluetooth control task 409 sends a response of “NG” directly to the facsimile manager 401 without sending a command to the facsimile apparatus 201, and the facsimile manager 401 displays “transmission impossible” when it receives the response of “NG”. When the transmission possible/impossible part of the state information is “possible” the Bluetooth control task 409 sends to the Bluetooth controller 410 a request for return to Active to communicate with the facsimile apparatus 201.
The Bluetooth controller 410, which receives the request for return to Active, communicates with the Bluetooth controller 309 of the facsimile apparatus 201 in accordance with the communication recovery procedure of Bluetooth. When the communication is recovered, the Bluetooth controller 410 sends mode change notification to the Bluetooth control task 409. When the Bluetooth control task 409, which receives the mode change notification, determines from the contents thereof that the communication has been recovered, it sends the transmission instruction command to the facsimile apparatus 201, and thereafter makes transition from the command return mode to the command through mode.
When it is determined from the contents of the mode change notification that the communication cannot be recovered, or no response is given from the Bluetooth controller 410 for a predetermined time period or more, the Bluetooth control task 409 retains the state of the command return mode as ever, and sends the answer of “NG” to the facsimile manager 401. When the facsimile manager 401 receives the answer of “NG”, it displays on the display unit a message showing that a transmission service is impossible.
Similarly, the Bluetooth controller 309 of the facsimile apparatus 201 sends mode change notification to the Bluetooth control task 308. When the Bluetooth control task 308, which receives the mode change notification, determines from the contents thereof that the communication has been recovered, it makes transition from the command return mode to the command through mode, and goes into the state of waiting for a command from the intelligent terminal 202. On the other hand, when it is determined that the communication cannot be recovered, the Bluetooth control task 308 retains the sate of the command return mode as ever.
The event control 307 that receives the transmission instruction command sends a response of “OK” to the intelligent terminal 202 when it ensures that the facsimile apparatus 201 is not currently under communication, and is not full of reservations for transmission, while it sends a response of “NG” when these conditions are not satisfied.
When the facsimile manager 401 receives the response of “OK” from the facsimile apparatus 201, it carries out transmission image data transfer procedure by the command interface same as that when connected with cables such as serial interfaces such as RS40132C, and parallel interfaces such as Centronics (standard interface defined in IEEE 1284, etc.). Furthermore, the transmission image data transfer procedure is similar to that in
When the Bluetooth control task 409 of the intelligent terminal 202 determines that transmission has been completed, it sends the state information acquirement command to the facsimile apparatus 201, and stores the state information included in the response, whereby the stored state information is made to follow the state change of the facsimile apparatus 201 after operation instruction. When receiving this response, the Bluetooth control task 409 requests transition to the Park mode to the Bluetooth controller 410 to make transition of communication with the facsimile apparatus 201 to the Park mode being a low power consumption mode again. The Bluetooth controller 410, which receives the request for transition to the Park mode, carries out procedure for transition to the Park mode based on the specification of Bluetooth, with the Bluetooth controller 309 of the facsimile apparatus 201. When the transition procedure is completed, the Bluetooth controllers 309 and 410 notify the Bluetooth control tasks 308 and 409, respectively, of the transition to the Park mode. When the Bluetooth control tasks 308 and 409 receive the notification of the transition to the Park mode, each of them makes transition to the command return mode.
Again, the command return mode is retained until the user starts a service such as facsimile transmission, scan or print at the intelligent terminal 202, or the state of the facsimile apparatus 201 changes.
When the power of the facsimile apparatus 201 is turned on, the process in
When the power of the intelligent terminal 202 is turned on, the facsimile manager 401 is started, and the Bluetooth control task 409 sends “Inquiry” to the Bluetooth controller 410 at step S4001.
At step S4002, whether or not the facsimile apparatus 201 responded to the sent “Inquiry” is determined, and if it responded normally, the process proceeds to step S4004, and if it did not respond normally, the process proceeds to step S4003.
At step S4003, the display unit of the intelligent terminal 202 is notified of the fact that there exists no facsimile apparatus that can be connected, followed by ending this process.
At step S4004, a connection request is sent to the Bluetooth controller 410, and the process proceeds to step S4005.
At step S4005, a response to the connection request is waited, and when notification of “failure in connection request” is given from the Bluetooth controller 410, the process proceeds to step S4006, and when notification of “success in connection” is given, the process proceeds to step S4007.
At step S4006, the display unit of the intelligent terminal 202 is notified of the failure in connection to the facsimile apparatus 201, followed by ending this process.
At step S4007, “Ready” showing that connection to the facsimile apparatus 201 could be done is transmitted to the facsimile manager 401, and the process proceeds to step S4008, where transition to the command through mode is made. At this time, the command through mode is an operation mode in which when the Bluetooth control task 409 receives a command from the facsimile manager 401, this command is sent to the Bluetooth controller 410, and when a response is received from the Bluetooth controller 410, this response is sent to the facsimile manager 401.
When the facsimile manager 401 receives the above described Ready signal, it uses “Serial Port Profile” to carry out the initialization process between the facsimile manager 401 and the event control task 307 of the facsimile apparatus 201.
At step S4009, completion of the initialization process is waited, and when the initialization process is completed, the process proceeds to step S4010.
The Bluetooth control task 409 sends the reception information acquirement command at step S4010, and a response to the command is received, and state information included therein is stored at step S4011. At step S4012, transition to the Park mode is requested to the Bluetooth controller 410 to make transition of communication with the facsimile apparatus 201 to the Park mode being a low power consumption mode. At step S4013, whether or not notification of transition to the Park mode has been received is determined, and if the transition notification has not been received, the process proceeds to Step S4012, where the request for transition to the Park mode is made again. At this time, error display may be provided to end the process after several retries.
If the notification of transition to the Park mode has been received, the process proceeds to step S4014 to make transition to the command return mode, and notification of this power on process is given.
Furthermore, the command return mode of the Bluetooth control task 409 will be described later using
In
First, “notification of state change” will be described.
Whether or not state information has changed from the state information stored theretofore is determined (step S4104) to know whether or not the state of the facsimile apparatus 201 has changed, and if it has changed, the process proceeds to step S4106 to notify the intelligent terminal 202 of the state information. At step S4106, return to the Active mode is requested to the Bluetooth controller 309 so that communication with the intelligent terminal 202 can be performed.
When communication with the intelligent terminal 202 becomes possible, transition to the command through mode is made, and each of checks at step S4108, step S4110 and step S4114 is repeated. In the command through mode, as suggested by its name, the command and data received from the Bluetooth controller 310 at step S4108 are sent to the event control task 307 (step S4109), and the response and data received from the event control task 307 are sent to the Bluetooth controller 310 (step S4113).
A request for return to Active is made from the facsimile apparatus 201 only in the case of the “notification of state change”, and the intelligent terminal 202 sends the state information acquirement command for this request. When the facsimile apparatus 201 sends back a response of this command, this is detected at step S4111, and the state information included in the response is stored (step S4112), followed by sending the same to the intelligent terminal 202. When the intelligent terminal 202 receives the response of this command, it requests transition of the operation mode to the Park mode. When the transition to the Park mode is completed, the Bluetooth control task 308 is given mode change notification, and thus detects this at step S4114, and returns to the command return mode to go into the standby state.
The “notification of state change” process of the facsimile apparatus 201 has been described above, and if the state of the facsimile apparatus 201 changes, both the Bluetooth control task 308 of the facsimile apparatus 201 and the Bluetooth control task 409 of the intelligent apparatus 202 are notified of the change of the state.
The case will now be described where “received image upload” and “transmission instruction command”, namely “operation instruction request command” are sent from the intelligent terminal 201.
Before sending “operation instruction request command”, the intelligent terminal 201 requests return to Active. When the facsimile apparatus 201 receives the request for return to Active, procedure for return to Active is carried out between the Bluetooth controllers 309 and 410. When returning to the Active mode, the Bluetooth controller 309 sends mode change notification to the Bluetooth control task 308. When the Bluetooth control task 308 of the facsimile apparatus 201 receives the mode change notification in the standby state, namely in the command return mode, it detects this notification at step S4105, and proceeds to step S4107 to make transition to the command through mode.
After transition to the command through mode, the command and data sent from the intelligent terminal 202 are received from the Bluetooth controller 309 at step S4108, and are sent to the event control task 307 at step S4109, and the response and data thereto are received from the event control task 307 at step S4110 and are sent to the Bluetooth controller 309 at step S4113. Thereby, a series of commands and data of requested operations can be exchanged between the facsimile manager 401 of the intelligent terminal 202 and the event control task 307 of the facsimile apparatus 201.
When this process is completed, the state information acquirement command is sent from the Bluetooth control task 409 of the intelligent terminal 202 to update the state information. When the event control task 307 sends a response thereto to the Bluetooth control task 308, this response is detected at step S4111, and is stored at step S4112. By this process, the Bluetooth control task 308 can store the latest state information after requested operation.
When the Bluetooth control task 409 of the intelligent terminal 202 receives the response to the state information acquirement command, it requests transition to the Park mode to the Bluetooth controller 410, and procedure for transition to the Park mode is carried out between the Bluetooth controllers 309 and 410. When the transition to the Park mode is completed, mode change notification is sent from the Bluetooth controller 309 to the Bluetooth control task 308. The Bluetooth control task 308 detects this notification at step S4114, and returns to the command return mode to go into the standby state.
In
When receiving the “state information acquirement command” at step S4204, the Bluetooth control task 409 creates a response with the stored state information, and sends the response to the facsimile manager 401 at step S4205.
The state information that is used at this time is the information that was transmitted from the facsimile apparatus 201 when connection to the facsimile apparatus 201 was recovered, and was stored. If the state of the facsimile apparatus 201 changes, a request for return to Active from the facsimile apparatus 201 to provide notification thereof. When return to the “Active” state is made, mode change notification is sent from the Bluetooth controller 410 to the Bluetooth control task 409.
When the Bluetooth control task 409 receives the request for return to Active from the facsimile apparatus 201, it detects the mode change notification at step S4206 to check whether or not the state of the facsimile apparatus 201 has changed, and then sends the state information acquirement command to the Bluetooth controller 410 at step S4207. At step S4208, response from the facsimile apparatus 201 is waited, and when the response is received, the state information is stored at step S4209. When the update of the state information is completed, transition to the Park mode is requested to make transition to the state of standby at step S4210.
The case will now be described where the “operation instruction command” such as the “received image upload command” and “transmission instruction command” is sent from the facsimile manager 401.
When the “operation instruction command” is received at step S4201, the Bluetooth control task 409 determines from the stored state information of the facsimile apparatus 201 whether or not execution of the operation for which instructions are provided is possible at step S4202. If it is determined that execution is not possible, a response of “NG” is sent to the facsimile manager 401 at step S4203 without sending the “operation instruction command” to the facsimile apparatus 201. On the other hand, if it is determined that execution is possible, a request for return to “Active” is sent to the Bluetooth controller 410 at step S4211, and when return to “Active” is made, transition to the command through mode is made, and the operation instruction command is sent to the Bluetooth controller 410 at step S4212.
In the command through mode, a series of command and data of instruction operations received from the facsimile manager 401 at step S4213 are sent to the Bluetooth controller 410 at step S4214, and the response and data received from the Bluetooth controller 410 at step S4215 are sent to the facsimile manager 401 at step S4216.
At this time, when exchange of a series of commands, responses and data of instruction operations is completed, this completion is detected at step S4217, and the process proceeds to step S4207.
The state information acquirement command is sent to the Bluetooth controller 410 at step S4207, a response is received at step S4208, state information is stored at step S4209, transition to the Park mode is requested to the Bluetooth controller 410 at step S4210, and transition to the command return mode is made to return to the standby state.
In this way, the state information of the facsimile apparatus 201 is stored in the Bluetooth control tasks 308 and 409 by the processes described using
As described above, also in this embodiment, it is made possible to reduce power consumption by send/receive of commands to poll the state of the image processing apparatus and responses thereto, without occupying the radio channel.

<Initialization Operation of Cordless Hand Scanner 430>
The initialization operation of the cordless hand scanner 430 in this embodiment will now be described.
First, a work area in the first RAM 4302 shown in
In this condition, when an Inquiry command based on the Bluetooth specification is received from the main part B, the ID number of the main part B in the command (Bluetooth device address) is compared with the ID number of the connectable main part B stored in advance (Bluetooth device address) (S4807). If the result of this comparison shows that they match each other, an Inquiry Response including an Inquiry access code of the hand scanner is sent to the main part B (S4808).
Then, when a Paging message (wireless connection request signal) including the device access code of the hand scanner 430 is received from the main part B (S4809), a wireless connection response signal is sent to the main part B (S4810) to establish a wireless link. Furthermore, the link type that is used in this embodiment is an asynchronous connectionless link (ACL). Unless an effective command is received from the main part B within a predetermined time period after the establishment of the wireless link, the Bluetooth baseband processing unit 4309 and the 2.4 GHz high frequency unit 4310 enters the Park mode (S4811).
Furthermore, the “Park mode” is a low power consumption standby state in which the connection of Bluetooth remains established.
As described with
<Initialization Operation of Main Part B>
An initialization operation of the main part B in this embodiment will now be described.
When the power of the main part B is turned on, a power on operation is performed in the following procedure.
When the main power supply is turned on (S5001), the work RAM is initialized (S5002), and peripheral hardware is initialized (S5003). Thereby, the display of the operation panel in main part 4324 is initialized.
Then, backup data in the SRAM 4313, and the image memory and the voice memory in the second RAM are checked (S5004). Subsequently, the Bluetooth control task is initialized (S5005), and an Inquiry command including the Inquiry access code of the main part B is sent to establish the link of Bluetooth with the cordless hand scanner 430 (S5006).
At this time, if the cordless hand scanner 430 is in the state of waiting establishment of the link of Bluetooth, an Inquiry Response including the Inquiry access code of the cordless hand scanner 430 is sent. If the Inquiry Response is received within a predetermined time period (S5007 to S5008), the main part B compares the Inquiry access code of the connectable hand scanner stored in advance with the received ID number (S5009), and makes transition to the Paging mode if the comparison result shows that they match each other.
That is, the device access code of the cordless hand scanner 430 is designated, and wireless connection using the Serial Port Profile is requested based on Bluetooth connection standard (S5010).
When a response signal to the wireless connection request is received from the cordless hand scanner 430 (S5011), the link of Bluetooth (Piconet) is established between the main part B and the cordless hand scanner 430, and thus a scanner interface initialization process shown in
Furthermore, if a response to the connection request is not received from the cordless hand scanner 430 after predetermined time elapses, impossibility of establishment of the wireless link is displayed on the display unit.
Also, if the Inquiry Response cannot be received within a predetermined time period after the Inquiry command is sent (NO at S5008) and if the Inquiry Response is received from an opposite with which connection cannot be made (NO at S5009), the process returns to S5006 to send the Inquiry command again.
<Operation of Interface Between Main part B and Hand Scanner>
First, the structure of a packet that is exchanged between the cordless hand scanner 430 and the main part B will be described.
According to the specification of Bluetooth, one packet is divided into an access code portion, a header portion and a payload portion, and the access code portion and header portions are used for Bluetooth communication, and the payload portion is used for the interface command/response between the main part B and the hand scanner unit. The payload portion is further constituted by a Mail_ID portion, a MAIL portion, a DATA_SIZE portion and DATA portion.
The MAIL_ID portion is used for managing matching of the interface command/response such as the MAIL name and version information of the interface command/response described later. In the MAIL portion are stored information (image number and color, effective time for waiting the command/response, etc.) needed for a predetermined interface command/response between the main part B and the hand scanner, and detailed instructions (instructions of what, how, etc.) of the command/response.
The Data_Size portion is used for managing the size of the DATA portion described later. For example, when there exists no DATA, NULL (Zero) is stored in the DATA_SIZE portion. DATA portion is used for storing therein data (for example, image data) that is not included in the MAIL portion.
In
Version is a management version of an interface command/response, Line_up is MAIL_ID for an image data upload, Total_size is a total size of the payload portion, and Response indicates a response that is issued on the basis of the request command. Also, Re_command is an instruction to the main part B in a case where there are some operation instructions or error on the hand scanner, for example instructions of STOP, CANCEL, REPLAY, PAUSE, NULL and the like.
Mail_size is an information size included in MAIL, the image number/image size/resolution/color/compression mode indicate information of the image to be transferred, 1_Line_size is a data size of 1 line of the read image, and 1_Line_data is data of 1 line of the read image.
(54-1) and (54-2) ensure that the interface command/response can be exchanged between the main part B and the hand scanner unit. For example, version information, etc. of the interface command/response is exchanged, thereby managing mutual matching.
At S5501, a connection request command (54-1) is sent to the cordless hand scanner 430, and a connection confirmation response (54-2) is received from the cordless hand scanner 430 (S5502), and then the main part B ensures that the cordless hand scanner 430 has been connected normally. At this time, whether or not the cordless hand scanner 430 is mounted on the main part B is determined, on the basis of the level of a signal that is inputted from the scanner interface connector 4323 (S5503), and if the cordless scanner 430 is mounted on the main part B, a pre-scan request command (54-3) is sent to the cordless hand scanner 430 (S5504).
When the cordless hand scanner 430 receives the pre-scan request command, it performs a pre-scan operation. Specifically, it performs light adjustment to determine lighting time of a light source, and stores the determined lighting time of the light source and shading data in the first RAM 4302 (S5505). The result of performing the pre-scan is sent back to the main part B as a pre-scan confirmation response (54-4). For this response, OK is written in MAIL if pre-scan could be performed normally, and NG is written in MAIL if failed in pre-scan, in command.
When the main part B receives the pre-scan confirmation response (54-4) (S5507), the hand scanner initialization procedure is completed. In case of NG, pre-scan is performed again, and error processing is performed in case of three NGs in succession (S5508).
When the above described process is carried out, the inside of the cordless hand scanner 430, the inside of the main part B and the scanner interface between the cordless hand scanner 430 and the main part B are initialized, thus bringing about a situation in which various kinds of operations can be performed on the basis of instructions by the user.
Also, if the cordless hand scanner 430 is not mounted on the main part B at S5503, a pre-scan confirmation command is sent from the main part B to the cordless hand scanner 430 at S5509. When the cordless hand scanner 430 receives the pre-scan confirmation command, it confirms the contents of the first RAM 4302, and sends back to the main part B the pre-scan confirmation response (54-4) having MAIL with OK written therein if normal pre-scan is already performed and its data is correctly retained in the cordless hand scanner 430, while it send back to main part B the pre-scan confirmation response (54-4) having MAIL with NG written therein if pre-scan is not performed yet or data is not correctly retained (S5510).
The main part B ends the process (S5511) if receiving OK, while it warns no scanner mounting described below to prompt the user to mount the cordless hand scanner 430 on the main part B for performing pre-scan (S5512).
A specific operation thereof will now be described using
Alarm display for prompting the user to mount the cordless hand scanner 430 on the main part B is provided using the operation panel in main part 4324, and the cross point switch 4317 is set to rumble an alarm sound (S5601). Thereafter, the level of a signal to be inputted in the scanner interface connector 4323 is monitored, and when the cordless hand scanner 430 is mounted on the main part B (S5602), alarm rumbling and alarm display are stopped (S5603) to complete the operation.
The process returns to
Furthermore, as described with
<Operation During Sheet Copy>
When copy instructions are provided from the operation panel in main part 4324 (S5801), a sensor placed in the original inlet 4404 detects existence/not existence of original (S5802), and assumes a sheet copy mode if the original exists. Whether or not the cordless hand scanner 430 is mounted on the main part B is determined based on the level of the signal inputted from the scanner interface connector 4323 (S5803), and if the cordless hand scanner 430 is mounted on the main part B, a procedure for transition to the Active mode is carried out (S5804) to make transition of the cordless hand scanner 430 from the Park mode (low power consumption standby state) to the Active mode for establishing the wireless link.
At S5901, the main part B sends an Unpark_req command being a request for transition to the Active mode to the cordless hand scanner 430. An Accepted response being notification of completion of transition to the Active mode from the cordless hand scanner 430 is waited for a predetermined time period, and when the Accepted response is received (S5902), the transition of the cordless hand scanner 430 to the Active mode is confirmed (S5904), and the process is ended. Furthermore, if the Accepted response cannot be received within a predetermined time period (S5903), the process returns to S5901, where an Unpark_req command is sent again.
Returning back to
At S5808, when a response of confirmation of preparation of line read (57-4) with OK/NG written in MAIL is received from the cordless hand scanner 430 (S5808), the printer is prepared (S5809).
When printer preparation is completed, a read start command (57-5) is sent to the cordless hand scanner 430 at S5810. Then, transportation of the original is started, image data is transferred from the cordless hand scanner 430 to the main part B, and record data subjected to necessary image processing is recorded by the printer 4325 in succession (S5811). The image data is stored in the DATA portion, an image data size for one interface command/response is each stored in the DATA_SIZE portion. Also, instructions for operations are each time stored in the MAIL portion, and thus when a stop key is pressed in the main part B, for example, the instructions there of are stored in the MAIL portion and are sent to the hand scanner.
When transportation of all originals is completed, a command of request of completion of line read (57-6) is sent to the cordless hand scanner 430 at S5812. However, the above described command of completion of line read may be stored in the MAIL portion of interface command/response, to which the last record data is sent.
At S5813, when a response of confirmation of completion of line read (57-7) is received from the cordless hand scanner 430, the operation of sheet copy is ended.
Furthermore, at S5803, if the cordless hand scanner 430 is not mounted on the main part B, the user is prompted to mount the cordless hand scanner 430 on the main part B (S5814), but this operation has been described with
Also, at S5802, an operation of hand scanner memory copy is performed if there exits no original, but this operation will be described in detail later.
<Operation During Sheet Transmission>
The interface chart of this operation is identical to that in
The key of the operation panel in main part 4324 is used to select the opposite from the telephone directory stored in the SRAM 4313, and if FAX transmission instructions are provided (S6001), a sensor (not shown) provided in the original inlet 4404 detects existence/not existence of original (S6002), and a sheet transmission mode is assumed if there exists a original. Whether or not the cordless hand scanner 430 is mounted on the main part B based on the level of the signal inputted from the scanner interface connector 4323 is determined (S6003), and if the cordless hand scanner 430 is mounted on the main part B, a procedure for transition to the Active mode is performed (S6004) to make the cordless hand scanner 430 in the Park mode (low power consumption state) to the Active mode for establishing the wireless link. The specific procedure is same as that described using
When the procedure for transition to the Active mode is completed, the connection request command (57-1) is sent to the cordless hand scanner 430 (S6005). When the connection confirmation response (57-2) is received from the cordless hand scanner 430 (S6006), the command of request of preparation of line read (57-3) is sent to the cordless hand scanner 430 (S6007) from the main part B.
At S6008, when the response of confirmation of preparation of line read (57-4) with OK/NG written in MAIL is received from the cordless hand scanner 430 (S6008), an origination operation is performed to connect to the communication line (S6009). When connection to the communication line is established, and a response is given from the opposite of FAX transmission destination, the read start command (57-5) is sent to the cordless hand scanner 430 at S6010. Then, transportation of the original is started, image data is transferred from the cordless hand scanner 430 to the main part B, and the transferred image data is demodulated with the facsimile modem 4316 before it is sent to the communication line (S6011). The method for transferring image data has been described in the section of sheet copy.
When transportation of all originals is completed, the command of request of completion of line read (57-6) is sent to the cordless hand scanner 430 at S6012. However, the above described command of completion of line read may be stored in the MAIL portion of interface command/response, to which the last record data is sent.
When the response of confirmation of completion of line read (57-7) is received from the cordless hand scanner 430 at S6013, the communication line is disconnected (S6015), and the operation of facsimile transmission of the sheet original is completed.
Furthermore, at S6003, if the cordless hand scanner 430 is not mounted on the main part B, the user is prompted to mount the cordless hand scanner 430 on the main part B (S6015), but this operation is same as that described with
Also, at S6002, an operation of hand scanner memory transmission is performed if there exists no original, but this operation will be described in detail later.
<Operation During Hand Scanner Copy by Operation of Main Part B>
In the hand scanner operation panel 4307, when read start instructions are provided (S6201), the image data read in accordance with movement of the scanner is compressed to JPEG image data and stored in the memory (S6202). This operation is continued in the hand scanner operation panel until read stop instructions are provided.
Then, when copy instructions are provided from the operation panel in main part 4324 (S6203), a sensor (not shown) existing in the original inlet 4404 detects existence/not existence of original (S6204), and if the original exists, the previously described sheet copy mode is assumed. If no original exists, it is assumed that the image data stored in the hand scanner is printed, and a process for transition to the Active mode is carried out (S6205) to make transition of the cordless hand scanner 430 in the Park mode to the Active mode as described with
When the procedure for transition to the Active mode is completed, a connection request command (61-1) is sent to the cordless hand scanner 430 (S6206). When a connection confirmation response (61-2) from the cordless hand scanner 430 is received (S6207), a hand scanner state request command (61-3) is sent to the cordless hand scanner 430 (S6208) to receive the image information (monochrome/color, etc.) in the hand scanner.
When a hand scanner state confirmation response (61-4) is received (S6209), an image transfer preparation request command (61-5) is sent from the main part B to the cordless hand scanner 430 (S6210). When an image transfer preparation confirmation response (61-6) with OK/NG written in MAIL is received from the cordless scanner 430 (S6211), the printer is prepared (S6212).
When preparation of the printer is completed, an image transfer start request command (61-7) is sent to the cordless hand scanner 430 (S6213). The image data that has been stored in the memory of the cordless hand scanner 430 is stored in the DATA portion of the interface command. In addition, command data is transferred to the Bluetooth baseband processing unit, and is sent to the main part B via the 2.4 GHz high frequency unit (S6214). The main part B that receives the image data converts the received image data into 360 dpi print data to perform color printing (S6215).
When an image transfer completion confirmation command is received from the cordless hand scanner 430 to complete print of all the data, the copy operation is completed.
When given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode.
<Operation During Hand Scanner/Facsimile Transmission by Operation of Main Part B>
The interface chart of this operation is similar to that in
In the hand scanner operation panel 4307, when read start instructions are provided (S6301), the image data read in accordance with movement of the scanner is compressed to JPEG image data and stored in the memory (S6302). This operation is continued in the hand scanner operation panel until read stop instructions are provided.
Then, when a facsimile transmission operation is performed using a telephone directory button on the operation panel in main part 4324 (S6303), existence/not existence of original is detected by a sensor (not shown) existing in the original inlet 4404 (S6304), and if the original exists, the previously described sheet transmission mode is assumed. If no original exists, it is assumed that the image data stored in the hand scanner is subjected to facsimile transmission, and a process for transition to the Active mode is carried out (S6305) to make transition of the cordless hand scanner 430 in the Park mode to the Active mode as described with
When the procedure for transition to the Active mode is completed, the connection request command (61-1) is sent to the cordless hand scanner 430 (S6306). When the connection confirmation response (61-2) from the cordless hand scanner 430 is received (S6307), the hand scanner state request command (61-3) is sent to the cordless hand scanner 430 (S6308) to receive the image information (monochrome/color, etc.) in the hand scanner.
When a hand scanner state confirmation response (61-4) is received (S6309), the image transfer preparation request command (61-5) is sent from the main part B to the cordless hand scanner 430 (S6310). When the image transfer preparation confirmation response (61-6) with OK/NG written in MAIL is received from the cordless scanner 430 (S6311), the image transfer start request command (61-7) is sent (S6312).
The hand scanner, which receives the image transfer start request command, starts an operation of sending to the main part B the image data stored in the memory (S6313). The image data is stored in the DATA portion of an interface command/status. Specifically, JPEG compression image data stored in the memory is transferred to the Bluetooth baseband processing unit, and is sent to the main part B via the 2.4 GHz high frequency unit.
In the main part B that receives the image data, the received image data is stored in the memory. When an image transfer completion confirmation response (61-9) is received (S6314) from the hand scanner, an operation of transmission to the partner defined by the telephone directory is performed (S6315). When the response is received from the transmission partner, the image data stored in the memory is modulated by the facsimile modem and sent to the communication line (S6316). When all the image data is sent, the communication line is opened, and the operation is completed.
When given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode.
<Operation During Hand Scanner Copy by Operation of Hand Scanner 430>
In the operation panel 4307 of the hand scanner 430, when read start instructions are provided (S6501), the image data read in accordance with movement of the hand scanner 430 is compressed to JPEG image data and stored in the memory (S6502). This operation is continued in the operation panel 4307 of the hand scanner 430 until read stop instructions are provided (S6503).
Then, when copy instructions are provided from the operation panel 4307 of the hand scanner 430 (S6504), an access request message requesting transition to the Active mode is sent to the main part B to establish the wireless link for transferring the stored image data to the main part B (S6505). When a command of response of notification of transition to the Active mode (UnPark message), the establishment of the wireless link is confirmed.
Subsequently, a connection request command (64-1) is sent from the main part B to the cordless hand scanner 430 (S6507). The cordless hand scanner 430 sends a connection confirmation response (64-2) to the main part B, and when the main part B receives this command and the connection confirmation response (S6508), it sends to the cordless hand scanner 430 a hand scanner state request command (64-3) for receiving image information (monochrome/color, etc.) in the hand scanner 430 (S6509). When the hand scanner state confirmation response (64-4) is received (S6510), an image transfer preparation request command (64-5) is sent from the main part B to the cordless hand scanner 430 (S6511).

The image data is stored in the DATA portion of an interface command/status. Specifically, JPEG compression image data stored in the memory is transferred to the Bluetooth baseband processing unit 4309, and is sent to the main part B via the 2.4 GHz high frequency unit. The main part B that receives the image data converts the received image data into 360 dpi print data to perform color printing (S6515). When transfer of image data is completed, a transfer completion request command (64-8) is sent from the cordless hand scanner 430 (S6516). When this command is received (S6517) and print of all the data is completed, the copy operation is completed.
When given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode. A series of operation theretofore is similar to the operation shown in FIG. 66, for example.
In the above operation, the case is assumed where a copy instruction operation is performed after the image is read by the hand scanner 430. However, the copy instruction operation may be performed before the image is read. In this case, particularly, it is also possible to read images while transferring the read images to the main part B and has the images printed. Specifically, when the copy instruction operation is performed by the hand scanner 430, the access request message requesting transition to the Active mode is sent to the main part B. When the command of response of notification of transition to the Active mode (UnPark message) is received, the transition to the Active mode can be confirmed. Subsequently, the image data transmission request command is sent from the main part B.
When the hand scanner 430 receives an image data transmission permission command from the main part B, it provides a display permitting the start of reading of images (display such as “Start reading”). When reading is started according to the read permission display, the read image data is subjected to JPEG compression and stored in the memory.
If the amount of image data stored in the memory reaches a certain level or higher, the image data is transferred to the Bluetooth baseband processing unit 4309, and is sent to the main part B via the 2.4 GHz high frequency unit 4310. The main part B that receives the image data converts the resolution of the received image data, and print can be started.
When read by the hand scanner 430 is completed, and read completion command instructions are provided, the hand scanner 430 sends an image data transmission completion notification command to the main part B. The main part B transfers the image data that is received until the image data transmission completion notification command to the printer unit to print the image data. When print of all the data is completed, a print completion notification command is sent to the hand scanner 430. The hand scanner 430, which receives the print completion notification command displays “Copy is completed” on the display unit, and the copy operation in the hand scanner 430 is completed.
When given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode.
Furthermore, image data that is newly read can be stored in the area of the memory 4302 in the hand scanner 430 storing the image data of which transmission has been completed. In this way, by performing read and transmission of image data at a time, the memory amount can be reduced, and time for copy can be reduced as well.
<Operation During Hand Scanner/Facsimile Transmission by Operation of Hand Scanner 430>
The interface chart of this operation is similar to that in
In the operation panel 4307 of the hand scanner 430, when read start instructions are provided (S6701), the image data read in accordance with movement of the hand scanner is compressed to JPEG image data and stored in the memory (S6702). This operation is continued in the operation panel 4307 of the hand scanner 430 until read stop instructions are provided (S6703).
Performing thereafter FAX transmission only by the operation of the hand scanner 430 requires notification and designation of the telephone number of the partner to the main part B. Data of telephone number can be sent to the main part B if it is stored in the DATA portion of the interface command/status, but an operation of designating the number itself by the hand scanner 430 occurs.
An operation of designating the FAX number of the transmission destination using the operation unit of the hand scanner 430 will now be described using
First, FAX transmission is selected from the function menu, and the user optionally designates an image to be sent. Thereafter, the FAX number of the partner being a transmission destination is designated, as shown in
Then, when the send image and the FAX number of the partner are decided using the operation panel 4307 of the hand scanner 430 as described above, and a facsimile transmission operation is performed (S6704), the access request message requesting transition to the Active mode is sent to the main part B (S6705). When the command of response of notification of transition to the Active mode (UnPark message) is received, the establishment of the wireless link is confirmed (S6706). When the procedure for transition to the Active mode is completed, the connection request command (64-1) is sent to the cordless hand scanner 430 (S6707). The cordless hand scanner 430 sends the connection confirmation response to the main part B, along with the transmission instruction command including instructions of facsimile transmission and the FAX number of the partner. When the main part B receives the transmission instruction command and the connection confirmation response (64-2) from the cordless hand scanner 430 (S6708), it sends to the hand scanner 430 the hand scanner state request command (64-3) for receiving image information (monochrome/color, etc.) in the hand scanner 430 (S6709).
When the hand scanner 430 receives the above described hand scanner state request command (64-3), it sends the hand scanner state confirmation response (64-4). When the main part B receives the above described hand scanner state confirmation response (64-4) (S6710), the image transfer preparation request command (64-5) is sent from the main part B to the cordless hand scanner 430 (S6711).
When the image transfer preparation response (64-6) with OK/NG written in MAIL is received from the cordless hand scanner 430 (S6712), an image transfer start request command (64-7) is sent (S6713).
The hand scanner 430 that receives the image transfer start request command starts an operation of sending the image data stored in the memory to the main part B (S6714). The image data is stored in the DATA portion of the interface command/status. Specifically, the JPEG compression data stored in the memory is transferred to the Bluetooth baseband processing unit 4309, and is sent to the main part B via the 2.4 GHz high frequency unit 4310.
In the main part B that receives the image data, the received image data is stored in the memory. When an image transfer completion confirmation response (64-9) is received from the hand scanner 430 (S6715), an operation of transmission to the FAX number of the partner previously received from the cordless hand scanner 430 is performed (S6716). When a response is received from the transmission destination, the image data stored in the memory is modulated by the facsimile modem, and is sent to the communication line (S6717). When all the image data is sent, the communication line is opened, and the operation is completed.
When given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode.
For the above described operation, transmission of image data is started by transmission instructions with the operation panel 4307 of the hand scanner 430 after read of the image data by hand scanner 430 is completed. However, transmission instructions may be provided with the operation panel 4307 of the hand scanner 430 before read by the hand scanner 430 is started. In this case, particularly, it is also possible to send the read image data to the opposite terminal while the image is read.
Specifically, when a facsimile transmission instruction operation is performed in the hand scanner 430, the access request message requesting transition to the Active mode is sent to the main part B. When the command of response of notification of transition to the Active mode (UnPark message) is received, the transition to the Active mode is confirmed. When the hand scanner 430 confirms the transition to the Active mode, it sends to the main part B a transmission instruction command including instructions of facsimile transmission and the FAX number of the partner. The main part B sends back a response to the transmission instruction command, and sends the image data transmission request command to the cordless hand scanner 430. When the hand scanner 430 receives the image data transmission permission command from the main part B, it provides a display permitting the start of reading of images (display such as “Start reading”). When reading is started according to the read permission display, the read image data is subjected to JPEG compression and stored in the memory.
If the amount of image data stored in the memory reaches a certain level or higher, the image data is transferred to the Bluetooth baseband processing unit 4309, and is sent to the main part B via the 2.4 GHz high frequency unit 4310.
The main part B that receives a certain amount or more of image data stores the image data in the memory, and performs transmission to the previously received FAX number of the transmission destination. When a response is given from the transmission destination, the image data stored in the memory is modulated by the facsimile modem, and is sent to the communication line.
When the read by the hand scanner is completed, and read completion instructions are provided, the hand scanner 430 sends the image data transmission completion notification command to the main part B. The main part B sends to the communication line the image data received before receiving the image data transmission completion notification command, and then sends the transmission completion notification command to the hand scanner 430 when transmission of all the data is completed. The hand scanner 430 that receives the transmission completion notification command displays “Communication is completed” on the display unit to complete the facsimile transmission operation.
When given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode.
Furthermore, image data tat is newly read can be stored in the memory area storing therein the image data of which transmission from the hand scanner 430 to the main part B has been completed. In this way, by performing read and line transmission of image data at a time, the memory amount can be reduced, and time for copy can be reduced as well.
<Image Erase Operation of Hand Scanner by Operation of Main Part B>
In the operation in the main part B, when image erase instructions are provided (S7001), a procedure for transition to the Active mode is carried out to make transition of the cordless hand scanner 430 in the Park mode to the Active mode for establishing a wireless link to erase image data in the hand scanner 430 as described using
When the procedure for transition to the Active mode is completed, a connection request command (71-1) is sent to the cordless hand scanner 430 (S7003). When a connection confirmation response (71-2) from the cordless hand scanner 430 is received (S7004), a hand scanner state request command (71-3) for confirming the state of the hand scanner 430 is sent to the cordless hand scanner 430 (S7005).
When a hand scanner state confirmation response (71-4) is received (S7006), an image erasing request command (71-5) indicating instructions to erase an image and information for identifying the image to be erased is sent from the main part B to the cordless hand scanner 430 (S7007). When an image erasing confirmation response (71-6) with OK/NG written in MAIL is received from the cordless hand scanner 430 (S7008), the hand scanner state request command (71-3) for confirming the result of erasing the image is sent to the cordless hand scanner 430 (S7009).
When the hand scanner state confirmation response (71-4) including information indicating that erase of the designated image has been completed (S7010), completion of the image erase operation is confirmed.
When a given time passes after the operation is completed, the cordless hand scanner 430 sends a Park_req message to the main part B, and makes transition to the Park mode.
<Operation at the Time of Dropping of Battery Voltage in Hand Scanner 430>
As described above, the cordless hand scanner 430 is driven by a battery 4308 charged by the main part B. Therefore, if the voltage of the battery 4308 drops, the cordless hand scanner 430 should be mounted on the main part B for charging it. For this charge, in the cordless hand scanner 430, by a task activated at an interval of 5 milliseconds, a battery voltage detecting circuit (not shown) reads the voltage of the battery 4308, and if it is equal to or higher than a preset warning start voltage (1.9 V in this embodiment) it is considered as normal (S7302), a warning flag is cleared, and a warning display of the LCD 4601 on the scanner operation unit 4307 is cleared (S7303) to complete the operation.
If the voltage of the battery 4308 is equal to or lower than a warning start voltage at S7302, the battery warning flag is set (S7304), and the operation is temporarily stopped if the hand scanner 430 is under operation (S7305). If the hand scanner 430 is not under operation at S7305, a warning display is provided on the LCD 4601 on the scanner operation unit 4307 (S7306). At this time, the display is highlighted by flashing or reversing the display. Then, if the wireless interface with the main part B is not in the Active state (S7307), the access request message is sent (S7308) to make transition to the Active mode, and when the Unpark message from the main part B is received within a predetermined time period (S7309), a charge request message is inputted in the payload portion of the response packet and is sent (S7311). The main part B that receives the charge request message warns no scanner mounting described with
Furthermore, the Unpark message from the main part B cannot be received within a predetermined time period (S7310), the process returns to S7308, where the access request message is sent again. Also, if the wireless interface with the main part B is in the Active state at S7307, the charge request message is sent immediately (S7311).
If the cordless hand scanner 430 is mounted on the main part B for changing, a warning displayed on the LCD 4601 on the scanner operation unit 4307 may be cleared.
Also, in
Furthermore, the facsimile apparatus in this embodiment also performs a reception operation, but since this operation is based on a known process, description of thereof is omitted.
In the sixth embodiment, the wireless connection between the main part B and the hand scanner 430 is performed by exchanging the Inquiry command during initialization. That is, the inquiry command is exchanged, whereby the ID number can be exchanged among Bluetooth devices. However, in a usual facsimile apparatus, the main part B and the hand scanner 430 are manufactured and sold as a set.
Therefore, the seventh embodiment is an embodiment in which the ID number of the cordless hand scanner 430 is stored in the nonvolatile memory of the main part B in advance, and conversely the ID number of the main part B is stored in the nonvolatile memory of the cordless hand scanner 430 in advance, thereby making it possible to omit the exchange with the Inquiry command.
In this case, the main part B designates the ID number of the cordless hand scanner 430, and makes the wireless connection request using Serial Port Profile, based on the Bluetooth connection specification. When the cordless hand scanner 430 ensures that its ID number is included, it sends a wireless connection response signal, and the wireless link (Piconet) is established.
Furthermore, by storing the hopping sequence of the initialization setting operation in the nonvolatile memory in advance, the wireless link can be established quickly.
Thereafter, it operates based on a procedure similar to the procedure in the sixth embodiment.
In the sixth embodiment, transition to the Active mode is made when the operation is started, and transition to the Park mode is made when the operation is completed.
By the way, in the Park mode, power is also consumed because radio waves are exchanged regularly.
Then, the eighth embodiment is an embodiment in which sending of the radio wave is fully stopped in the case where wireless data communication is not performed for long hours, thereby making it possible to reduce power consumption.
Specifically, according to the third embodiment, as shown in
Furthermore, in
Also, if the send of the radio wave is stopped during a predefined time frame such as nighttime, and Piconet is reestablished in the morning, power consumption can be reduced.
Also, in the above described embodiment, the Park mode has been described as a low power consumption standby state, but power consumption can also be reduced similarly in the Hold mode or Sniff mode.
In the above described embodiment, in the case where the image read by the hand scanner 430 is transmitted to the communication line, only facsimile transmission is assumed.
This ninth embodiment is an embodiment in which the image read by the hand scanner 430 is converted into an electronic mail format to send the same as an electronic mail in the case where the image read by the hand scanner 430 is transmitted to the communication line. Also in this case, processes of timing of control of Bluetooth are identical to the processes in the above described respective embodiments.
As described above, according to the above sixth to ninth embodiments, since timing of the send of the radio wave is changed after a wireless data send/receive operation is completed, communication in the Piconet between the image communication apparatus and the portable scanner, etc. is curbed or stopped to curb the send of the radio wave or emit no radio wave when given time passes after the operation is completed, thus making it possible to reduce power consumption and use effectively frequency resources, and reducing a possibility that interference occurs when other terminals communicate.
Also, because the send/stop of the radio wave is switched depending on time, quick wireless connection can be achieved when the possibility of using wireless communication is high, while power consumption can be reduced as much as possible when the possibility of using wireless communication is low.
Also, because the mode of wireless communication can be changed depending on predetermined operations of the portable scanner such as selection of copy operation or transmission operation, hand copy can be performed by operating only the portable scanner even if the portable scanner exists at a location some distance from the image communication apparatus, when hand copy is required in the portable scanner, and facsimile transmission can be performed by operating only the portable scanner even if the portable scanner exists at a location some distance from the image communication apparatus, when facsimile transmission of the image read by the portable scanner is required, for example.
Furthermore, needless to say, a storage medium storing a program code of software achieving the function of the above described each embodiment is supplied to a system or apparatus, and the computer (or CPU and MPU) of the system or apparatus reads and executes the program code stored in the storage medium, whereby the object of the present invention is achieved.
In this case, the program code itself read from the storage medium achieves a new function of the present invention, and thus the storage medium storing the program code constitutes the present invention.
For storage media for supplying program codes, for example, floppy disks, hard disks, optical disks, magneto-optical disks, CD-ROMs, CD-Rs, magnetic tapes, nonvolatile memory cards, ROMs and the like may be used. Also, the program code may be supplied from the server computer via the communication network.
Also, needless to say, not only the case where the computer executes the read program code, whereby the function of the above described each embodiment is achieved, but also the case where the OS or the like operating on the computer performs part or all of actual process based on instructions of the program code, by which the function of the above described each embodiment is achieved is included.
Furthermore, needless to say, the case is also included where after the program code read from the storage medium is written in the memory provided in a feature expansion board inserted in the computer and a feature expansion unit connected to the computer, the CPU or the like provided in the feature expansion board and the feature expansion unit performs part or all of actual process based on instructions of the program code, by which the function of the above described each embodiment is achieved.
As described above, according to the present invention, an effect can be exhibited such that when the apparatus is not in a serviceable state, because it is automatically put into a state of the low electric power consumption, without depending on an arrangement or a command for moving to the low electric power consumption, the wireless connection process portion is put into the state of the low electric power consumption, so that the wireless communication traffic reduced, the limitation of wirelessly performing other services with other apparatuses can be minimized and the electric power consumption in a stand-by state time can be minimized.
Moreover, when there is available an image or the like to be sent wirelessly after moving to a state of the low electric power consumption, the state of the low electric power consumption can be released immediately, so that the apparatus can be moved to the state of the low electric power consumption without impairing the usability of the apparatus.
