Facsimile apparatus for processing received image data according to sub-address signal

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invent on relates to a facsimile apparatus and a communication control method having a sub-address function.
Also, the invention relates to a facsimile apparatus and a facsimile communication method having a sub-address function or a password function which is an additional function in CCITT (International Telegraph and Telephone Consultative Committee) recommendation/T.30.
2. Related Background Art
In CCITT SG8 meeting held in April, 1993, it has been determined that the sub-address, the password, and the selective polling function is additionally recommended. Herein, the recommendation regarding the sub-address involves notifying the presence or absence of a sub-address receiving function to the transmitter in terms of bit 49 of a DIS/DTC signal, and sending 20-digit information with a SUB signal when the sender designates the sub-address.
Since the presence or absence of the receiving function of a sub-address signal can be designated in terms of the DIS signal, the SUB signal (sub-address signal) can be transmitted or received between other manufacturer's stations. Accordingly, the communication between the self station and other manufacturer's station had a significant drawback that if the operation based on the SUB signal in the receiver end is different from the operation based on the SUB signal in the sender end, the communication based on the sub-address information can not be correctly executed, causing a malfunction.
Also, the communication between the same manufacturer's stations had a further drawback that different settings of using the SUB signal between the sender end and the receiver end would result in a malfunction.
SUMMARY OF THE INVENTION
It is an object of the present invention to define a method of using the sub-address signal in the facsimile apparatus.
It is another object of the invention to provide a facsimile apparatus which can make the communication by the method of using the sub-address signal to be consistent between the sender end and the receiver end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
EXAMPLE 1
A facsimile apparatus and a communication control method thereof according to one embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing the electrical configuration of the facsimile apparatus. A CPU 1 is a central processing control unit for controlling the whole of the apparatus in accordance with the contents of programs stored in a ROM 2. A RAM 3 is used as the work area of the CPU 1 as required.
A contact sensor (CS) 9 serves to read the original, read original being compressed and encoded through a read control gate array (R.sub.-- CNT) 10, and stored in an image memory (DRAM) 13, with the image management information such as a reception number, destination information, the number of pages, stored image memory block information, and an operation command being stored in a RAM 4. The image data stored in the image memory 13 is expanded and decoded by a record gate array (W.sub.-- CNT) 11, and printed on the recording sheet by a laser beam printer (LBP) 12, the recording sheets as printed being sorted by a sorter (SORTER) 18. Also, the image data stored in the image memory 13 is PM-AM demodulated by a modulator-demodulator (MODEM) 14, and then sent to the line through an NCU (Network Control Unit) 15 or sent to an external computer (not shown) through a driver (DRIVER) 19.
Also, if the received image is input into the modem 14 through the NCU 15, it is demodulated by the modem 14, expanded and decoded, and checked for image error. As a result of checking, if it is correct without any image error, the received image is compressed and encoded, and stored in the image memory (DRAM) 13, and the image management information is stored in the RAM 4.
The operator can make a variety of designations or settings by depressing a key (KEY) 8, its content being stored and displayed on a display unit (LCD) 7 according to the following procedure. That is, the CPU 1 detects input data upon depressing the key 8 via a panel control gate array (OP.sub.-- CNT) 6 and displays necessary data on the LCD 7. The CPU 1 sends an output signal to a voice IC (VOICE.sub.-- IC) 16, in accordance with the information stored in the RAMs 3 to 5, and outputs the voice from a speaker 17.
FIG. 2 is an explanatory chart showing the format of a sub-address for use in the facsimile apparatus of this embodiment. The sub-address 21 consists of a 20-digit number (20 bytes), the first three bytes storing a memory box number 22 which is a memory box ID (identification number) as the three-digit number. FIG. 3 is an explanatory view showing the contents of a memory box. The memory box is allocated to the RAM 4 and the DRAM 13, consisting of an image management record (area for storing image information), an image storing area, and a memory box management record (area for storing management information of the memory area subdivided into some blocks). The components within the memory box will be apparent from the description as follows.
Next to the memory box number 22, a delimiter 23a of one byte is arranged which is a separator for clarifying the internal configuration of the sub-address 21.
The next two bytes store an operation command represented by a two-digit number (100 numbers from 00 to 99). The further next one byte stores a delimiter 23b.
In the 8-th byte and beyond, data 25 required for executing the operation command 24 is stored.
While in this example, the sub-address was defined by using the delimiter, it should be noted that the delimiter is not necessarily defined if the format of sub-address is predefined. Also, regarding the size and storage location of the memory box number 22, the operation command 24 and the data 25, the format is not limited to this example, but may be defined arbitrarily.
FIGS. 4 and 5 are flowcharts showing a control routine for analyzing the operation command within the sub-address (SUB) received. This routine is started upon the facsimile apparatus on the called side receiving the image and declaring the presence of sub-address function to the facsimile apparatus on the calling side, using the DIS signal (digital identification signal).
First, in order to declare the presence of sub-address function to the facsimile apparatus on the calling side, the 49-th bit of DIS (digital identification signal) is set to "1" (step S1), and the DIS (digital identification signal) is sent to the facsimile apparatus on the calling side (step S2).
Subsequently, the operation waits for a SUB (sub-address) and a DCS (digital instruction signal) which the facsimile apparatus on the calling side sends out to be received (step S3), and if the SUB (sub-address) is not received, this routine is ended and transfers to a normal communication control procedure that follows, upon receiving the DCS (digital instruction signal).
If the SUB (sub-address) which the facsimile apparatus on the calling side sends out is received at step S3, the facsimile apparatus on the called side picks up the memory box number from the SUB (sub-address) and converts it to the int type, which is stored in a temporarily set memory box management record.
In this way, the facsimile apparatus on the called side has memory boxes and elements box.sub.-- no, box.sub.-- order, dial.sub.-- bit.sub.-- map corresponding to the total memory box number, each element being distinctly discriminated for every memory box.
FIGS. 6 and 7 are flowcharts showing a record task routine which is activated periodically by the facsimile apparatus on the called side. First, the facsimile apparatus on the called side checks for a status file.sub.-- status within the image management record stored as the image processing mode in accordance with the operation command number of sub-address, to determine whether or not the output of image is required (step S31). If the output of image is not required, the operation transfers to step S36. If the output of image is required, a temporarily set sorter address tmp.sub.-- sort.sub.-- adrs is initialized to the value "0" (step S32).
A check is performed to determine whether or not the image can be output to a sorter designated by the sorter address tmp.sub.-- sort.sub.-- adrs (step S33). When the image can be output to the sorter designated by tmp.sub.-- sort.sub.-- adrs, the operation transfers to the next step S35 unless the bit corresponding to the sorter address tmp.sub.-- sort.sub.-- adrs is high in a map sort.sub.-- bit.sub.-- map where the sorter address within the image management record is stored, in order to determine whether or not the image is requested to output to that sorter. If that bit is high (that is, "1"), the image is output to the sorter at step S34. Note that the image is output at the address having the sort.sub.-- bit.sub.-- map of 1, and not output at the address having the sort.sub.-- bit map of 0.
At step S35, the sorter address tmp.sub.-- sort.sub.-- adrs is incremented. A check is performed to see whether or not the sorter address tmp.sub.-- sort.sub.-- adrs exceeds the maximum value MAX.sub.-- SORT.sub.-- ADRS of sorter address (step S36), and if not, the operation returns to step S33. If the sorter address tmp.sub.-- sort.sub.-- adrs exceeds the maximum value MAX.sub.-- SORT.sub.-- ADRS of the sorter address, the operation goes to step S37, since the image has been output to all the sorters to which the output of image is requested at steps S32 to S36.
Subsequently, a check is performed to see whether or not the output SW of the memory box report is on (step S37), and if the output SW is off, the operation is ended.
If the output SW is on, a check is performed to see whether or not the output of report is requested (step S38), by reading the status file.sub.-- status within the image management record, and if not requested, this routine is ended. If the output of report is requested, the temporarily set sorter address tmp.sub.-- sort.sub.-- adrs is initialized to the value "0" (step S39). If there is any further sorter requested for the output of report, a check is performed to see whether or not the bit corresponding to the sorter address tmp.sub.-- sort.sub.-- adrs is high in the map sort.sub.-- bit.sub.-- map where the sorter address is stored (step S40), and if that bit is high, the report is output to the sorter designated by the sorter address tmp.sub.-- sort.sub.-- adrs (step S41), and the sorter address tmp.sub.-- sort.sub.-- adrs is incremented (step S42). If the bit is not high at step S40, the operation transfers directly to step S42. Then, a check is performed to see whether or not the sorter address tmp.sub.-- sort.sub.-- adrs exceeds the maximum value MAX.sub.-- SORT.sub.-- ADRS of sorter address (step S43), and if not, the operation returns to step S40. If it exceeds, this routine is ended, since the report has been output to all the sorters to which the output of report is requested. In this way, the report can be output to all the sorters to which the output of report is requested by executing the processings at steps S37 to S43.
FIGS. 8 and 9 are flowcharts showing a communication task routine which is activated periodically by the facsimile apparatus on the called side. This routine processes a stored image. First, a check is performed to see whether or not the sending of image is requested by reading the status file.sub.-- status within the image management record stored as the image processing mode corresponding to the operation command number of sub-address (step S61). If the sending of image is not requested, this routine is ended, or if the sending of image is requested, a check is performed to see whether or not a dial map dial.sub.-- bit.sub.-- map where the telephone number within the memory box is stored is NULL (step S62). If the dial map dial.sub.-- bit.sub.-- map is NULL, the operation transfers to step S68. If not, a temporarily set dial address tmp.sub.-- dial.sub.-- id is initialized to the value "0" (step S63).
Next, to obtain the sending destination, a check is performed to see whether or not the bit corresponding to the dial address tmp.sub.-- dial.sub.-- id is high in the dial map dial.sub.-- bit.sub.-- map (step S64), and if that bit is high, the image is sent to a destination designated by the dial address tmp.sub.-- dial.sub.-- id (step S65), and the dial address tmp.sub.-- dial.sub.-- id is incremented (step S66). If the bit is not high in the dial map dial.sub.-- bit.sub.-- map at step S64, the operation transfers directly to step S66. Note that the actual telephone number corresponding to each address of dial.sub.-- bit.sub.-- map is stored in the RAM 5.
Then, the dial address tmp.sub.-- dial.sub.-- id is checked to see whether it exceeds the maximum value of destination id (identification number) (step S67). If not, the operation returns to step S64, or if the dial address tmp.sub.-- dial.sub.-- id exceeds the maximum value, the operation transfers to step S68. In this way, by executing steps S62 to S67, the image is sent to all the destinations for which the sending of image is requested.
Subsequently, at step S68, a check is carried out to determine whether or not an IP address map ip.sub.-- bit.sub.-- map within the memory box is NULL, and if NULL, the operation transfers to step S74. If the IP address map ip.sub.-- bit map is not NULL, a temporarily set IP address ip.sub.-- bit.sub.-- id is initialized to the value "0" (step S69).
Next, to obtain the sending destination, a check is performed to determine whether or not the bit in the IP address map ip.sub.-- bit.sub.-- map corresponding to the IP address ip.sub.-- bit.sub.-- id is high (step S70). If the bit in the IP address map ip.sub.-- bit.sub.-- map is high, the image is sent to the destination designated by the IP address ip.sub.-- bit.sub.-- id (step S71), and the IP address ip.sub.-- bit.sub.-- id is incremented (step S72). At step S70, if the bit in the IP address map ip.sub.-- bit.sub.-- map is not high, the operation transfers directly to step S72.
Subsequently, the IP address ip.sub.-- bit.sub.-- id is checked to determine whether or not it exceeds the maximum value of the IP address map ip.sub.-- bit.sub.-- map (step S73), and if not, the operation returns to step S70. If the IP address ip.sub.-- bit.sub.-- id exceeds the maximum value of the IP address map ip.sub.-- bit.sub.-- map, the operation transfers to step S74.
At step S74, a check is performed to determine whether or not a dial buffer dial.sub.-- buf within the memory box is NULL (step S74), and if not NULL, the image is sent to the destination of the dial buffer dial.sub.-- buf (step S75), and a communication result report is created and sent in accordance with a status file.sub.-- status within the image management record (step S76), after which this routine is ended. If the dial buffer dial.sub.-- buf is NULL at step S74, the operation transfers to step S76. In this way, by performing the processings at steps S61 to S76 for all the image management records, the sending of all the images requested is ended.
As described above, with the facsimile apparatus and its communication control method of the present invention, the recording and sending of the image received using the sub-address can be performed.
Next, a facsimile apparatus on the calling side and its communication control method will be described below.
FIG. 10 is a flowchart showing a sub-address registration routine which is executed by the facsimile apparatus on the calling side.
In the facsimile apparatus on the calling side, a memory box registration mode is entered (step S91), and a memory box number desired to register is input (step S92).
Subsequently, the operation transfers to a sub-address registration mode (step S93). And the memory box number input at step S92 is written into the first three bytes of the sub-address (step S94), and a delimiter is written into the 4-th byte of the sub-address (step S95), before registering an operation command in the sub-address. Also, the operation command desired to designate with the sub-address is input by a key 8 in the format of operation command number (step S96), and the input operation command number is registered in two bytes from the 5-th byte of the sub-address (step S97). After the operation instruction number is registered in the sub-address, the delimiter is written into the 7-th byte of the sub-address (step S98). Further, as necessary data for the operation command, data such as a telephone number, a one-touch telephone number, an abbreviated telephone number, an extension, and a sorter address are input by the key 8 such as a ten key, a one-touch key, an abbreviation key, a cursor key, a set key or a function key (step S99), and the data is written into the 8-th byte and downwards of the sub-address (step S100). Then, a series of routines for registering the operation command in the sub-address is ended.
FIG. 11 is a flowchart showing a sub-address send-out routine which is executed by the facsimile apparatus on the calling side. The facsimile apparatus on the calling side first checks to determine whether or not the 49-th bit of DIS (digital identification number) received from the facsimile apparatus on the called side is "1" (step S121). If the 49-th bit is not "1", this routine is immediately ended.
On the other hand, if the 49-th bit is "1" at step S121, the memory box number is stored in a variable tmp.sub.-- box.sub.-- no of sub-address number (step S4). The operation retrieves for a memory box having, as a component, a memory box number box.sub.-- no coincident with the memory box number stored in the variable tmp.sub.-- box.sub.-- no which the facsimile apparatus on the called side possesses (step S5).
Subsequently, the operation command number is picked up from the SUB (sub-address), and stored in a variable box.sub.-- order showing the operation command number which is a component of the memory box (step S6). Further, the image processing mode is stored in the status file.sub.-- status within the image management record to correspond to the operation command number stored in the variable box.sub.-- order (step S7).
The format of necessary data may differ depending on the operation command number stored in the variable box.sub.-- order. First, a check is performed to determine whether or not the operation command data is a telephone number such as a one-touch or abbreviated number (step S8). If so, the data is stored in the dial map dial.sub.-- bit.sub.-- map in the form of map (step S9). If not, a check is performed to see whether or not the operation command data is a sorter address (step S10). If the operation command data is the sorter address, the sorter address is stored in a sorter address map sort.sub.-- bit.sub.-- map in the form of map (step S11). If the operation command data is not the sorter address, a check is performed to see whether or not the operation command data is an IP address (step S12). If so, the operation command data is stored in an IP address map ip.sub.-- bit.sub.-- map in the form of bit map (step S13). If not, the operation command data is checked to determine whether or not it is a telephone number (step S14). If the operation command data is not the telephone number, its telephone number is stored in the dial buffer dial.sub.-- buf (step S15). If the operation command data is not the telephone number, this routine is ended.
Thereafter, in accordance with a normal communication control procedure, the image communication is made. The sent image and information regarding the image is stored in an image storing area for each memory box number, the sub-address (SUB) registered by an sub-address registration routine and a digital instruction signal (DCS) are sent out (step S122), and this routine is ended.
As described above, with the facsimile apparatus and its communication control method of the invention, in addition to the equivalent effects as previously described in the example 1, the more universal communications can be achieved because the facsimile apparatus on the calling side registers the sub-address by using the key, and sends out it, only if the facsimile apparatus on the called side admits the sub-address to be effective.
Next, there will be described a procedure for the facsimile apparatus on the called side to analyze an operation command when the operation command within the sub-address received is an "image output inhibit". FIG. 12 shows a process of reflecting the image processing mode at step S7 in FIG. 4 onto the status file.sub.-- status of the image management record.
The facsimile apparatus on the called side first determines whether or not the operation command box.sub.-- order picked up at step S6 in FIG. 4 is "image output inhibit" (step S141), and if the operation command is not "image output inhibit", the operation transfers to step S144, or otherwise, the operation transfers to step S142. At step S142, a bit B.sub.-- PIX.sub.-- SECLET signifying the image recording inhibit is set up in the status file.sub.-- status for each image management record. Subsequently, an output request bit B.sub.-- PIX.sub.-- PRT.sub.-- REP of the memory box report is set up in the status file.sub.-- status (step S143). At step S144, the main sorter address is set in the map sort.sub.-- bit.sub.-- map where the sorter address within the image management record is stored (step S144), whereby the setting of the image processing mode is ended.
As described above, with the facsimile apparatus and its communication control method of this example, it is possible to achieve a higher universality because the facsimile apparatus on the calling side can transmit by setting "image output inhibit" of the facsimile apparatus on the called side in the sub-address.
Next, an operation command analysis wherein the operation command within the sub-address received is a relay transmission or relay broadcast communication of transmitting the image to the designated apparatus or apparatuses will be described below.
FIG. 13 is a flowchart showing an image processing mode setting routine. This routine shows a process of reflecting the image processing mode at step S7 in FIG. 4 to the status file.sub.-- status of the image management record. The facsimile apparatus on the called side first determines whether or not the operation command number box.sub.-- order picked up at step S6 in FIG. 4 is a relay transmission or relay broadcast communication of transmitting the image to the designated apparatus or apparatuses (step S161). If it is not the relay transmission or relay broadcast communication, this routine is ended, but if it is, a bit B.sub.-- PIX.sub.-- TRN signifying the transmission of the image is set up in the status file.sub.-- status of the image management record (step S162). A transmission request bit B.sub.-- PIX.sub.-- REP.sub.-- TRN of the communication result report signifying the image transmission result is set up in the status file.sub.-- status of the image management record (step S163), and the setting of the image processing mode for this routine is ended.
And a sending operation for the relay transmission or relay broadcast communication is performed in accordance with the communication task routine of FIGS. 8 and 9 which is periodically activated, as previously described.
Since the B.sub.-- PIX.sub.-- REP.sub.-- TRN is set in the status file.sub.-- status within the image management record, the communication result report is created and sent out to the image sender (step S76), and this routine is ended.
As described above, with the facsimile apparatus and its communication control method of this example, the relay transmission or relay broadcast communication can be simply achieved using the sub-address.
Next, an operation command analysis wherein the operation command within the sub-address received is to output the image to the designated sorter will be described below.
A recording sheet from a laser printer 12 is output to a sorter 18, the sorter for output destination being designated by the sorter address tmp.sub.-- sort.sub.-- adrs. FIG. 14 is a flowchart showing an image processing mode setting routine. In this routine, at a step for setting the image processing mode at step S7 in FIG. 4 to the status file.sub.-- status within the image management record, a bit B.sub.-- PIX.sub.-- PRN.sub.-- SORT signifying the image output to a designated sorter is set up (step S182). Subsequently, an output request bit B.sub.-- PIX.sub.-- PRT.sub.-- REP of the memory box report is set up in the status file.sub.-- status within the image management record (step S183).
If the setting of designating the output sorter of the recording sheet is ended, the recording is performed in accordance with the record task routine of FIGS. 6 and 7 which is periodically activated.
As described above, with the facsimile apparatus and its communication control method of this example, the sorter address which is an output destination of image can be simply set using the sub-address.
Next, an operation command analysis wherein the operation command within the sub-address received is to output the image to the computer having a designated IP address will be described below. FIG. 15 is a flowchart showing an image processing mode setting routine. In this routine, a process of reflecting the image processing mode at step S7 in FIG. 4 to the status file.sub.-- status within the image management record is included.
The facsimile apparatus on the called side first determines whether or not the operation command number box.sub.-- order picked up at step S6 in FIG. 4 is to output the image to the computer having a designated IP address (step S201), and if it is not to output the image to the computer having the designated IP address, this routine is ended, or otherwise, the program goes to step S202.
At step S202, the bit B.sub.-- PIX.sub.-- TRN signifying the transmission of image is set up in the status file.sub.-- status. And the transmission request bit B.sub.-- PIX.sub.-- REP.sub.-- TRN of communication result report signifying the image transmission result is set up in the status file.sub.-- status within the image management record (step S203), and the setting of the image processing mode is ended.
Thereafter, the image is sent out to the computer having the designated IP address in the communication task of FIGS. 8 and 9.
As described above, with the facsimile apparatus and its communication control method of this example, the output of image to the apparatus such as a computer designated by the IP address can be simply accomplished using the sub-address.
EXAMPLE 2
An example 2 of the invention will be described below with reference to the drawings.
FIG. 16 is a block diagram showing the schematic configuration of the example of a facsimile apparatus according to the present invention.
In the figure, 501 is a central processing control unit (CPU) for controlling the whole of the apparatus in accordance with the contents of programs (including a program as shown in a flowchart of FIGS. 17 and 18 as hereinafter described) stored in a ROM 502. A RAM 503 is used as the work area as required. An original is read by a contact sensor 504, compressed and encoded through a read control gate array 505, and stored in an image memory (DRAM: dynamic RAM) 506. Then, the management information such as a reception number, destination information, the number of pages, stored image memory block information, and an operation command (attribute) is stored in a RAM 507 (image management record). Herein, each of the RAM 507 and the image memory 506 is divided into a plurality of blocks as the memory block, the information of each memory block being managed by a management record (RAM 507). And the memory box consists of a memory block and a management record.
The image stored in the image memory 506 is expanded and decoded by a record control gate array 508, and printed on the recording sheet by a laser printer 509, the recording sheets being sorted by a sorter 509A. Also, the image stored in the image memory 506 is digital-to-analog modulated (PM-AM modulation) by a modulator-demodulator (MODEM) 510, and then sent to the communication line 512 through an NCU (Network Control Unit) 511 for switching the line.
Also, the received image data is input through the NCU 511 into the modem 510 for the demodulation, expanded and decoded, and checked for image error. As a result of checking, if it is correct, the received image is compressed and encoded, and stored in the image memory 506. Then, the image management information is stored in the RAM 507.
Moreover, the operator can make a variety of designations or settings by depressing a key 513, wherein its content is held in a RAM 514, and can be confirmed on a display unit 515 such as a liquid crystal display (LCD). The CPU 501 detects input data from the key 513 via a panel control gate array 516 and displays necessary data on the display 515, as well as sending an output signal to a voice IC 517 based on the information of RAMs 503, 507, 514, to output the voice from a speaker 518.
Next, a communication operation of this example using a sub-address function or a password function which is an additional function of CCITT recommendation/T.30 will be described below.
FIG. 17 is a flowchart showing the operation on the image receiver end in this example.
First, in the execution of a facsimile communication protocol, to declare the presence of the sub-address function or password function to the calling side, a bit 49 or bit 50 of DIS (initial identification signal) is set to "1" (step S1011), and this DIS is sent out to the calling side (step S1012). Herein, the DIS represents a standard CCITT capability on the receiver end, and is composed in a predetermined format, the bit 49 indicating the sub-address capability and the bit 50 indicating the password capability.
Thereafter, the program waits for the sub-address (SUB) or password (PWD) which the caller sends out and a DCS (digital command signal: digital setting command responding to the standard function identified by the DIS), and determines whether or not the sub-address or password has been received (step S1013). If neither the sub-address nor the password is received, this flow is ended, and the program transfers to a normal procedure following the DCS reception.
If either or both of the sub-address and the password is or are received, a check is carried out to establish whether or not a sub-address and password coincident with its sub-address and password is present in the registered memory box (step S1014). If present, the sent image is stored in the memory box (step S1015), or if not present, a new memory box having registered the sub-address and the password which have been sent is created, the image being stored in this memory box as created (step S1016).
And when the attribute of the memory box indicates the content of "sending a report or previously stored image back to the partner station", for example, the sub-address and password of the memory box as well as the report such as a transmission report or the previously stored image are sent back to the partner station in accordance with the attribute of this memory box (step S1017), and this flow is ended.
FIG. 18 is a flowchart showing the operation on the image sender end in this example.
First, the DIS is received from the facsimile apparatus on the receiver end to check to determine whether or not the bit 49 or bit 50 is set to "1" (step S1021).
When the bit 49 or bit 50 is "1", the image with a predetermined sub-address or password is sent to the receiver end (step S1022). That is, since the bit 49 indicates the sub-address capability or the bit 50 indicates the password capability, as previously described, the image with the sub-address or password is sent accordingly. Each of the sub-address and the password is constituted of a 20-digit number (20 bytes).
Also, if neither the bit 49 nor the bit 50 is "1", the DCS is sent in accordance with the normal procedure.
Note that if both the bit 49 and the bit 50 are "1", the sub-address can be only sent with the image, or the password only sent with the image.
Thereafter, in accordance with the attribute of the memory box corresponding to the sub-address or password which the partner station has received, the report or previously stored image, for example, is received (step S1023), and this flow is ended.
In this way, with this example, the received image can be stored in a predetermined memory box on the receiver end using the sub-address/password, and the report such as a transmission report or previously stored image, for example, can be sent back to the partner station in accordance with the attribute registered in each memory box.
It should be noted that the present invention is not limited to the above example, but various variations can be made. For example, this example was described with the content of "sending a report or previously stored image back to the partner station" as the attribute of the memory box, but the content of the attribute can be set arbitrarily, and no data may be sent back to the partner station depending on the content.

2534 is an indicator circuit for indicating whether or not to send out the DIS signal indicating that the sub-address information is receivable, wherein the sending is effective if the sub-address information is received. The indicator circuit 2534 lights on an indicator when a clear pulse is generated in a signal line 2548e, and thereafter the lighting on and off of the indicator is repeated every time the depressed pulse is generated in the signal line 2532a. Also, the circuit 2534 outputs the signal with a signal level "1" to the signal line 2534a when the indicator is lighted on, or outputs the signal with a signal level "0" to the signal line 2534a when lighted off.

2538 is a maker storage circuit for storing the makers having control based on the sub-address information. The makers having control based on the sub-address information can be stored up to 20, for example. When a maker having control based on the sub-address information is registered in the circuit 2538, a registration number (any of 1 to 20, e.g., 1), a space, and its maker code (e.g., 21H) are output to a signal line 2538a, and then a line pulse is generated in a signal line 2548f. Also, when reading the information stored in the circuit 2538, the registration number (e.g., 1) is output to the signal line 2538a, and then a read pulse is generated in a signal line 2548g. By doing so, the maker code (e.g., 21H) registered corresponding to the registration number is output to the signal line 2538a.
2540 is a circuit for storing a particular partner for effecting the control based on the sub-address information. The particular partner for effecting the control based on the sub-address information is designated with lower 6-digits of the telephone number information, and up to 20 destinations are accepted. When the particular partner for effecting the control based on the sub-address information is registered in the circuit 2540, a destination number (any of 1 to 20, e.g., 3), a space and the lower 6 digits of the telephone number (e.g., 221144) are output to a signal line 2540a, and then a write pulse is generated in a signal line 2548h. Also, when reading the information stored in the circuit 2540, the destination number (e.g., 3) is output to the signal line 2540a, and then a read pulse is generated in a signal line 2548i. By doing so, the lower 6 digits of the telephone number (e.g., 221144) registered corresponding to the destination number is output to the signal line 2540a.

When registering the time A in the circuit 2542, 18:00, for example, is output to a signal line 2542a, and then a write pulse is generated in a signal line 2548j. Also, when reading the time A registered in the circuit 2542, a read pulse is generated in a signal line 2548k. By doing so, the time A (e.g., 18:00) registered in the circuit 2542 is output to the signal line 2542a.
2544 is a circuit for storing the time B when the control based on the sub-address information is made ineffective. When registering the time B in the circuit 2544, 20:00, for example, is output to a signal line 2544a, and then a write pulse is generated in a signal line 25481. Also, when reading the time B registered in the circuit 2544, a read pulse is generated in a signal line 2548m. By doing so, the time B (e.g., 20:00) registered in the circuit 2544 is output to the signal line 2544a.
2546 is a circuit for storing the time when the control based on the sub-address information is made effective corresponding to Monday to Sunday, and the time when it is made ineffective. When registering them in the circuit 2546, the day of the week information (1 for Monday, 2 for Tuesday, . . . and 7 for Sunday), a space, the time when the control is made effective (e.g., 7:00), a space, and the time when the control is made ineffective (e.g., 9:00) are output to a signal line 2546a, and then a write pulse is generated in a signal line 2548n. On the other hand, when reading the information registered in the circuit 2546, the day of the week information (e.g., 1) is output to the signal line 2546a, and then a read pulse is generated in a signal line 2548o. By doing so, the information registered in the circuit 2546 corresponding to the day of the week information, e.g., 7:00, a space, 9:00 is output to the signal line 2546a.
2548 is a control circuit for the facsimile apparatus which changes the output sorter position based on the sub-address information, upon receiving this information, the control circuit effecting the control in such a manner as to give notice of the sub-address function in terms of the DIS signal, and the changing function of the output sorter position with the designation of the SUB signal (sub-address signal) in terms of the NSF signal, and upon receiving a SUB signal and an NSS signal indicating that the control for changing the output sorter position with the designation of SUB signal is required, making the sub-address information effective to change the output sorter position based on the information, or upon not receiving the SUB signal or the NSS signal indicating that the control for changing the output sorter position with the designation of the SUB signal is required, ignoring the sub-address information to output the received information to the sorter 20.
