[0047] A reference numeral 21 denotes a control device for controlling the whole of the hand scanner.

[0048] A reference numeral 22 denotes a connecting device for connecting the scanner unit to the main body of the apparatus, which corresponds to the hand scanner connecting device 3.

[0049] A reference numeral 23 denotes an image data reading device such as close contact type reading sensor or reduced optical system and the like.

[0050] A reference numeral 24 denotes a storing unit for storing an image data which has been read.

[0051] A reference numeral 25 denotes operation buttons for instructing starting and ending of reading of the image data.

[0052]
FIG. 3 is a flow chart showing the operation of the facsimile apparatus when the scanner is mounted on the main body of the facsimile apparatus.

[0053] The control device 1 detects that the hand scanner 12 is connected to the hand scanner connecting device 3 (S31).

[0054] Subsequently, the control device 1 determines whether or not there is a new image data (S32).

[0055] If the number of frames of new image information which is transmitted via the hand scanner connecting device 3 from the hand scanner 12 is 0, the control device 1 causes the facsimile apparatus to be brought into a stand-by mode.

[0056] On the other hand, if the number of frames of the new image information which is transmitted via the hand scanner connecting device 3 from the hand scanner 12 is one or more, the control device 1 instructs the printing device 4 to print on a recording paper the image data which is transmitted from the hand scanner 12 via the hand scanner connecting device 3.

[0057] Alternatively, transmission can be conducted in lieu of printing operation. In this case, the destination of the transmission may be the numbers of the last called party.

[0058] In other words, if data which is failed to be transmitted is found after completion of the transmission, additional data can be transmitted to the just transmitted destination only by reading the image to be transmitted again by means of the hand scanner and mounting the hand scanner on the main body of the apparatus. It is very convenient.

[0059] If the hand scanner is mounted on the main body of the apparatus, selection whether printing or transmission of the image data is to be conducted may be preliminarily specified by mode switches. Alternatively, transmission may be conducted only when the hand scanner is removed from the main body for reading data and is mounted on the main body of the apparatus within a predetermined period of time after the transmission of data.

[0060] A term “new data” used herein means a stored data since the hand scanner is removed until it is mounted on the main body. Interruption of power to the main body of the apparatus causes the new data to be erased.

[0061] If no data is read even if the hand scanner is removed from the main body, the last stored data may be left as new data, or the last stored data may be stored as old data and it may be displayed that there is no new data.

[0062] Both new and old data are stored in the storing unit. Ease of use can be enhanced if the operator can select the storage mode such as storing of only new data, only old data or both new and old data after the new data is automatically printed as mentioned above.

[0063] Also in this case, operation for transmission processing may be executed in lieu of the operation for printing processing.

[0064] A method of managing of the image data may be carried out in the main body of the apparatus although the new data is stored in the hand scanner in this case.

[0065] For example, image information which is stored in the hand scanner is transferred to the main body of the apparatus and stored therein when the hand scanner is firstly mounted on the main body of the apparatus.

[0066] Then, when the hand scanner is mounted on the main body of the apparatus again after the hand scanner is removed, new data may be determined by comparing image information which is transmitted from the hand scanner and the previous image information which is stored in the main body of the apparatus.

[0067]
FIG. 4 is a flow chart showing the operation when image reading is conducted by means of the scanner.

[0068] The control device 21 determines whether a reading start button of the operation buttons 25 is depressed or not (S41).

[0069] When the control device 21 determines that the button is depressed, the control device activates the reading device 23 to store read image data in the storing device 24 (S42).

[0070] Simultaneously with this, the control device 1 causes the storing device 24 to store that the stored image data is a new data (S43).

[0071]
FIG. 5 is a flow chart showing the operation when the scanner is removed from the main body of the apparatus.

[0072] The control device 1 determines whether the hand scanner 12 is removed from the main body of the apparatus (S51).

[0073] Subsequently, when the control device 1 determines the hand scanner is removed, it determines whether there is new data in the image data stored in the storing device 24 (S52).

[0074] If there is new data, the control device 1 rewrites new data as old data for storage so that next read data is stored as new data (S53).

[0075]
FIG. 6 is a flow chart showing the operation when the scanner is mounted on the main body of the apparatus while reading is conducted by means of the scanner and when the amount of the image data exceeds the capacity of the storing unit.

[0076] When the reading button is depressed, retrieving for vacant image storing device is conducted (S61). The number of frames of image data is preset to 0 (S62). Image reading is started (S63).

[0077] The control device 1 determines whether an image data is generated or not (S64). The image data is stored (S65). The number of frames of image data is incremented by one (S66).

[0078] The control device 1 determines whether the storing device is filled with data or not (S67). If it determines that it is filled, it stops reading (S70).

[0079] If it is not filled, reading is continued. When the control device 1 determines that a stop button is depressed (S68), reading is stopped. If the control device determines that the scanner is mounted on the main body of the apparatus (S69) even when the stop button is not depressed, reading is stopped.

[0080] Now, a method of detecting when the scanner (also referred to as hand scanner or hand copier) is connected to the main body of the apparatus in accordance with the present invention will be described.

[0081] The hand scanner is connected to the main body of the apparatus via an electric connector. The connector includes a signal line which is formed so that connection of the hand scanner can be detected from the main body of the apparatus, and a signal line which is formed so that connection of the main body of the apparatus can be detected from the hand scanner as well as a signal line which is necessary for the transmission of the information between the hand scanner and the main body of the apparatus.

[0082] The main body transmits a connection confirmation command to the hand scanner when the connection of the hand scanner is detected by a hand scanner detecting device in the hand scanner connecting device 3. When the hand scanner receives the connection confirmation command from the main body of the apparatus, the hand scanner transmits the connection confirmation command to the main body of the apparatus. When the main body of the apparatus receives the connection confirmation command from the hand scanner, it confirms that the hand scanner is connected to the main body.

[0083] When the main body of the apparatus confirms the connection of the hand scanner, it inquires the hand scanner how many frames of the image are stored in the scanner or how many frames of new data exist.

[0084]
FIG. 7 is a table showing commands which are transmitted to the hand scanner from the main body of the apparatus. A command comprises three bytes. The first byte is used for identification of a command and second and third bytes are parameters.

[0085]
FIG. 8 is a table showing commands which are transmitted to the main body of the apparatus from the hand scanner. A command comprises three bytes. The first byte is used for identification of a command and second and third bytes are parameters as is similar to FIG. 7.

[0086] Processing sequence of the main body of the apparatus and the hand scanner will be described with reference to FIGS. 9 through 13.

[0087]
FIG. 9 shows sequence of processing when no image data is stored in the hand scanner although mounting of the hand scanner is detected. The main body of the apparatus detects the mounting of the hand scanner to send the connection confirmation command to the hand scanner and the hand scanner transmits the connection confirmation command. Then the main body of the apparatus send an image information command to the hand scanner and the hand scanner transmits the image information command.

[0088]
FIG. 10 shows processing sequence when one frame of new data is stored in the hand scanner. In addition to the processing sequence in FIG. 9, the main body of the apparatus sends an image output request command to the hand scanner and the hand scanner transmits an image output command to the main body of the apparatus.

[0089]
FIG. 11 shows the processing sequence when total one frame of image data is stored in the hand scanner and the number of the frames of the image data is 0. The sequence is substantially identical with that in FIG. 9 except that the content of the image information command which is transmitted to the main body of the apparatus from the hand scanner is different.

[0090]
FIG. 12 shows the processing sequence when one frame of new data is stored in the hand scanner after removing the hand scanner from the condition of FIG. 10. The sequence is substantially identical with that in FIG. 10 except that the content of the image information command and image output command which is transmitted to the main body of the apparatus from the hand scanner and the image output request command which is transmitted to the hand scanner from the main body of the apparatus are different.

[0091]
FIG. 13 shows the processing sequence when a processing state confirmation command is provided in addition to three commands such as connection confirmation command, image information command and image data output command shown in FIGS. 9 to 12.

[0092] The reason why this processing state confirmation command is provided is that it is necessary to prevent the image data which is being stored from being transmitted to the main body of the apparatus when the hand scanner is mounted on the main body of the apparatus in the course of reading of an image and to process the image data in the main body of the apparatus after completion of the image reading processing. If the hand scanner receives an image data output request while reading of the image is not completed, the image data is discontinued in the course of reception.

[0093] This processing state confirmation command is provided to return the state after the image reading by the hand scanner has been completed. Processing after completion of the image reading by the hand scanner may include storing of the image data, turning off of a reading lamp, which takes an extended period of time. The hand scanner sends a busy signal in response to the processing state confirmation command while the hand scanner is conducting processing after completion of the image reading.

[0094] The hand scanner sends a ready command if it completes the above mentioned processing. When the main body of the apparatus detects the ready command, the sequence proceeds to next command.

[0095] Storing mode of the storing device 24 for the hand scanner will be described in detail with reference to FIGS. 14 through 19.

[0096] The storing device of the hand scanner comprises a storing device having a buffer for storing the number of all frames of data and a buffer for storing the number of frames of new data and n units, each for storing the size of image data and one frame of image data. The storing units for storing the size of image data and image information is formed so that first image information is stored in the first area, the second frame is stored in the second area, . . . , n th frame is stored in n th area, and so on.

[0097] A new data is changed into an old data as follows. When image information is read by the hand scanner, the image information is stored in an image information storing area and information on the attribute of the image is stored in the buffer. After completion of reading, the number of frames of all data, the number of frames of new data are increased by one and stored. When it is detected that the hand scanner is removed from the main body of the apparatus, the buffers which store the number of frames of new data are reset to 0.

[0098] All the buffers are reset to 0 by initial presetting as shown in FIG. 15.

[0099] When the hand scanner is removed from the main body of the apparatus and reading is performed, it is determined that the first frame of data has been read since the number of all frames of all data is 0. The image data and image data size is stored in the storing device for image 1 depending upon respective read data as shown in FIG. 16, and the number of frames of all data and the number of frames of new data are increased by one respectively so that they becomes one.

[0100] When reading of image is conducted again by the hand scanner, it is determined that the second frame of image is read since the number of frames of all data is one. The image data and image data size is stored depending upon the data which is read into the storing unit of image 2 as shown in FIG. 17. Since the number of frames of all data and the number of frames of new data are added with 1, they become 2.

[0101] When the hand scanner is mounted on the main body of the apparatus, the number of frames of new data is 2 and the number of all data is also 2. Accordingly, image data on the first and second frames are automatically printed as new data.

[0102] When the hand scanner is removed from the main body of the apparatus, the number of frames of new data is reset to 0 as shown in FIG. 18. Since the number of frames of new data is 0 even if the hand scanner is mounted on the main body of the apparatus at this time, automatic printing is not performed.

[0103] When reading is carried out again by removing the hand scanner from the main body of the apparatus, image data and image data size is stored in an area of the image 3 depending upon the respective read data and the number of frames of all data and the number of frames of new data are added with 1, respectively. Accordingly, the number of frames of all data and the number of frames of new data becomes 3 and 1, respectively.

[0104] When the hand scanner is mounted on the main body of the apparatus, the number of frames of all data is 3 and the number of frames of new data is 1. Accordingly, it can be determined that only the last third frame of the image data (image 3) is new data. Only the third frame can be automatically printed.

[0105] In accordance with the present invention in a facsimile apparatus including numeric keys for entering dial numbers or abbreviated dial numbers, a transmission instruction key for instructing the processing for transmission, a storage unit for storing dial information and received information, a scanner which is removable from a main body of the apparatus having a reading and storing units, a scanner connecting unit for connecting said scanner to the main body of the apparatus and a printing unit for visually outputting an image data which is stored in said storing unit, the image data which is stored in the storing unit of the scanner is output by only mounting the scanner on the main body of the apparatus. Accordingly, it is not necessary to instruct printing by selecting the image data which an operator read so that ease of operation is enhanced.

[0106] In the facsimile apparatus in accordance with the preceding paragraph, the output image data is a data which is obtained since the scanner is removed from the main body of the apparatus until it is mounted thereon in accordance with the present invention. Accordingly, old image data which is previously read is not printed, but only the latest image data is treated resulting in saving of recording paper.

[0107] In accordance with the present invention, in a facsimile apparatus including numeric keys for entering dial numbers or abbreviated dial numbers, a transmission instruction key for instructing the processing for transmission, a storage unit for storing dial information and received information, a scanner which is removable from a main body of the apparatus having a reading and storing units, a scanner connecting unit for connecting said scanner to the main body of the apparatus and a printing unit for visually outputting an image data which is stored in said storing unit, reading can be terminated by mounting the scanner on the main body of the apparatus even if the scanner is reading data. No operator's operation is not necessary to terminate reading of the scanner resulting in enhanced ease of operation.

[0108] In accordance with the present invention, in a facsimile apparatus including numeric keys for entering dial numbers or abbreviated dial numbers, a transmission instruction key for instructing the processing for transmission, a storage unit for storing dial information and received information, a scanner which is removable from a main body of the apparatus having a reading and storing units, a scanner connecting unit for connecting said scanner to the main body of the apparatus and a printing unit for visually outputting an image data which is stored in said storing unit, the image data which is stored in the storing unit of the scanner is transmitted only by mounting the scanner on the main body of the apparatus. Instruction of transmission by selecting the image data which is read by the operator is not necessary, resulting in enhanced ease of operation.
