[0020]
FIG. 4 is a timing chart showing a communication procedure of signals transmitted and received between the calling-side facsimile apparatus and the called-side facsimile apparatus in the first embodiment. As shown in FIG. 4, first, the calling facsimile device dials the called facsimile device to make a call, and in response, the called facsimile device follows the CED signal. A DIS signal is transmitted to the calling facsimile machine. In response to this, the calling facsimile apparatus, together with the DTC signal, a PWD (password) signal including a password for polling reception, a SEP (selective polling) signal including a file number to be polled, and a PSA ( A Polled Sub Address (polling subaddress) signal is transmitted to the called facsimile machine. Here, as shown in FIG. 5A, the PSA signal stores 000... 000100 (20 bytes) in the FIF (facsimile information field). On the other hand, as shown in FIG. 5B, in the called facsimile machine, an FNV (Field Not Valid: facsimile information field including the following reason number in the FIF is incorrect in the following reason. The DIS signal is transmitted to the calling facsimile machine together with the signal. At this time, the called facsimile machine waits for a predetermined time until a predetermined signal is received.
[0021]
(A) Reason number 1: When the transmitted password does not match the password registered in advance in the RAM 7 of the called facsimile machine.
(B) Reason number 2: There is no file number.
(C) Reason number 3: There is no directory number.
(D) Reason number 4: Although there is a file number, image data corresponding to the file number is not stored in the image memory 8.
(E) Reason number 5: There is a directory number, but image data corresponding to the directory number is not stored in the image memory 8.
[0022]
For example, when the reason number is 2 or 3, the calling facsimile device displays “Please re-enter the corresponding file” on the display unit 4 and instructs the operator to re-enter. When the input is re-entered, the calling-side facsimile apparatus again, together with the DTC signal, a PWD (password) signal including a password for polling reception, and a SEP (selective polling) signal including a file number to be polled, A PSA (Polled Sub Address: polling subaddress) signal is transmitted to the called facsimile machine.
[0023]
6 and 7 are flowcharts showing a polling reception process executed by the main control unit 1 of the calling-side facsimile apparatus according to the first embodiment. In FIG. 6, first, when an operator inputs a directory number, a file number, and a password using the operation unit 5 in step S1, the line is closed and the telephone number of the other party's called facsimile machine is set in step S2. Send it out. In response to this, a DIS signal is received from the called facsimile machine in step S3, and the bit of the SEP signal of the DIS signal is determined in step S4. If the bit of the SEP signal is 0, Since the calling side facsimile apparatus cannot perform selective polling, a DCN signal is sent to the called side facsimile apparatus in step S14, and after that, in step S15, “the other party cannot be selectively polled” is displayed. Proceed to step S13 on the display unit 4.
[0024]
When the bit of the SEP signal is 1 in step S4, the called facsimile machine can perform selective polling. Therefore, in step S5, the directory number is stored in the PSA signal, the file number is stored in the SEP signal, After storing the password in the PWD signal and sending it to the called facsimile machine, the DTC signal is sent in step S6. Here, in step S7, it is determined whether or not the FNV signal is received and detected from the called facsimile machine. If the FNV signal is received, the process proceeds to step S20 in FIG. Since selective polling reception is possible, a DCS signal and a training signal are received from the called facsimile machine in step S8, and in response, a CFR signal is sent in step S9, and then in step S10. The image data of all pages is received and printed using the image recording unit 3. Next, in step S11, an EOP signal is detected from the called facsimile machine, and in response to this, an MCF signal is sent in step S12, and then the line is released in step S13 to end the polling reception process. .
[0025]
When the FFN of the FNV signal is determined in step S20 of FIG. 7 and FIF = 1, the PWD signal password does not match, so in step S21 the display of “Re-enter password does not match” is displayed. 4, it is determined whether or not it is the third input in step S <b> 22. If YES, the process proceeds to step S <b> 25. If NO, the operator re-enters the password using the operation unit 5 in step S <b> 23. In step S24, it is determined whether or not the stop key is pressed. If YES, the process proceeds to step S25 to stop the polling reception process. In step S25, a DCN signal is sent to In step S13, the line is released and the polling reception process is terminated. If NO in step S24, the process returns to step S5 in FIG. 6, and again transmits a signal for the selective polling signal to the called facsimile machine as shown in FIG.
[0026]
When FIF = 2 in step S20, there is no corresponding file number. In step S31, the message “No corresponding file exists” is displayed on the display unit 4. If NO, the process proceeds to step S25. If NO, the operator re-enters the file number using the operation unit 5 in step S33, and if a list is requested, the file number is requested. Enter "*" after or enter "*" only. In step S34, it is determined whether or not the stop key is pressed. If YES, the process proceeds to step S25 to stop the polling reception process. If NO, the process returns to step S5 in FIG. Then, a signal for the selective polling signal is transmitted again to the called facsimile machine. Here, the data of “file number + *” or “*” input in step S33 is stored in the SEP signal in step S5 and transmitted to the called facsimile apparatus. Each of the side facsimile apparatuses transmits the name corresponding to the file number or the image data of the list of file names in the form of facsimile communication. In response to this, the facsimile machine on the calling side prints the received list image data using the image recording unit 3.
[0027]
When FIF = 3 in step S20, there is no corresponding directory number. In step S41, the message “Please enter again without corresponding directory” is displayed on the display unit 4. If YES, the process proceeds to step S25. If NO, the operator re-enters the directory number using the operation unit 5 in step S43, and when requesting a list, the directory number Enter "*" after or enter "*" only. In step S44, it is determined whether or not the stop key is pressed. If YES, the process proceeds to step S25 to stop the polling reception process. If NO, the process returns to step S5 in FIG. Then, a signal for the selective polling signal is transmitted again to the called facsimile machine. Here, the data of “directory number + *” or “*” input in step S43 is stored in the PSA signal in step S5 and transmitted to the called facsimile machine. The facsimile machine on the side transmits the image data of each file name corresponding to the directory number or a list of file names belonging to the directory in the form of facsimile communication. In response to this, the facsimile machine on the calling side prints the received list image data using the image recording unit 3.
[0028]
When FIF = 4 in step S20, there is no image data corresponding to the corresponding file number. Therefore, in step S51, “Image data is not registered in the file of the corresponding number” is displayed on the display unit 4, and step S32 Then, the re-input process is performed in the same manner as described above.
[0029]
Further, when FIF = 5 in step S20, there is no image data corresponding to the corresponding directory number. Therefore, in step S61, “Image data is not registered in the directory of the corresponding number” is displayed on the display unit 4, In step S42, re-input processing is performed in the same manner as described above.
[0030]
As described above, according to the present embodiment, the facsimile apparatus 20 that polls and receives the image data stored in the image memory 8 of the counterpart facsimile machine requests the counterpart facsimile apparatus to transmit the image data. To send a signal containing information specifying the image data and the image data, receiving a signal containing the reason for not accepting the request from the other party's facsimile machine, and performing the display based on the reason. The reason for not accepting the request from the facsimile apparatus can be clearly determined in the calling facsimile apparatus.
[0031]
If there is no corresponding image data, a signal requesting transmission of image data including a list of image data names in the image memory 8 is transmitted to the other facsimile apparatus. Therefore, even when there is no image data of the designated file, a list of names can be requested while communication is ongoing. Accordingly, it is possible to save the operator's trouble of executing the polling reception process by disconnecting the line once and making a call again, and the operability can be improved.
[0032]
Further, when the program including the polling reception processing of FIG. 6 and FIG. 7 is recorded in, for example, the floppy disk 22a instead of being stored in the ROM 6, the ROM 6 has only the original functions of the facsimile apparatus. By simply storing the program and reading the program for polling reception from the floppy disk 22a, an optional function can be easily added.
[0033]
Further, when requesting a list of the file information table 7a to the called facsimile apparatus, a "*" code is input using the operation unit 5 after the file number or directory number, and the SEP signal or PSA is respectively input. Stored in signal and sent. Therefore, the operator can easily request a list of files, and the operability of the apparatus can be improved.
[0034]
Furthermore, when the passwords do not match (reason number FIF = 1), the password request is displayed again, and after entering the password, the polling request signal is sent again. Therefore, the line is temporarily disconnected. Thus, it is possible to save the operator's trouble of calling again and executing polling reception, and the operability can be improved.
[0035]
