Is possible.

Next, the operation of the CPU 11 when performing fax transmission will be described with reference to the flowchart of FIG.
When the FAX switch key 40 of the display / operation unit 14 is pressed, the CPU 11 of the digital multi-function peripheral 1 starts the transmission program shown in the flowchart of FIG. 4. First, the CPU 11 determines whether or not a destination fax number has been input. When the user inputs a fax number with the numeric keypad 32 on the destination input screen displayed on the LCD display unit 31 of the display / operation unit 14, the entered fax number is stored in the RAM 13 (step 101). 102).

  Next, the CPU 11 determines whether or not the start key 33 has been pressed (step 103). If it is determined that the start key 33 has been pressed, it is determined whether or not the polling document storage area 24 is set in the image memory 16. If it is determined (step 104) and it is determined that the polling document storage area 24 is not set in the image memory 16, for example, “Polling document storage area is not set. After displaying a message such as “Yes” (step 105), the program is terminated.

  On the other hand, if it is determined in step 104 that the polling document accumulation area 24 is set in the image memory 16, the CPU 11 acquires the document number of the polling document and stores it in the polling information storage unit 23 (step 106). The original set on the reading unit 15 is read, and the read image data is compressed by the codec 18 and then stored in the polling original storage area 24 of the image memory 16 (step 107).

  Next, the CPU 11 reads the document number stored in the polling information storage unit 23, creates a polling reception request document as shown in FIG. 5, encodes it into image data by the codec 18, and stores it in the image memory 16. (Step 108). Thereafter, the CPU 11 reads out the fax number of the transmission destination stored in the RAM 13 and controls the modem 19 and the NCU 20 to send them to the PSTN 5. When communication is established, the CPU 11 reads out the image data of the requested document from the image memory 16. After modulation at 19, the NCU 20 transmits a fax to the other party through the PSTN 5 (step 109).

Next, the operation when a polling transmission request is received will be described with reference to the flowchart of FIG.
The CPU 11 of the digital multi-function peripheral 1 always executes the reception program shown in the flowchart of FIG. 6 and determines whether there is an incoming call from another external facsimile machine or the like (step 201). If it is determined that there is an incoming call, the CPU 11 determines whether the incoming call is a polling transmission request (step 202). If it is determined that the incoming call is not a polling transmission request, the CPU 11 executes normal fax reception processing (step 203).

  On the other hand, when the recipient who has received the above notification of polling reception inputs the fax number, password, and document number of the digital multi-function peripheral 1 that has been contacted in advance and makes a polling transmission request, the CPU 11 proceeds to step 202. It is determined that the incoming call is a polling transmission request, and it is determined whether a password has been received (step 204). If it is determined that the password has not been received, the CPU 11 performs line disconnection processing (step 205), and then ends the program.

  If it is determined in step 204 that a password has been received, the CPU 11 determines whether or not the received password matches the password stored in the polling information storage unit 23 (step 206). If it is determined that they do not match, the CPU 11 performs line disconnection processing (step 205) in the same manner as described above, and then ends the program.

  On the other hand, if it is determined that the passwords match, the CPU 11 reads the transmission document data corresponding to the polling transmission document number received from the communication partner from the polling document storage area 24 of the image memory 16 and modulates it by the modem 19. , NCU 20 transmits to the other party through PSTN 5 (step 207).

As described above, the user can maintain confidentiality only by performing FAX transmission in operation without particularly being aware of polling accumulation.
That is, if the FAX number of the own facsimile apparatus and the password for polling reception are notified in advance to the transmission destination, when the other side receives the notification of polling reception, it can perform polling reception and acquire a desired document. At the same time, even if the above notification is sent by mistake and sent to the wrong party, the other party cannot know the information necessary for polling reception such as the fax number and password, so it is possible to prevent the document from being leaked. .

In the above embodiment, when fax transmission is performed, transmission is always performed using the polling function. However, normal fax transmission and transmission using the polling function can be selected. The operation when the transmission using the fax transmission and the polling function can be selected will be described with reference to the flowchart of FIG.
The apparatus configuration is the same as that shown in FIGS.

When the FAX switch key 40 of the display / operation unit 14 is pressed, the CPU 11 of the digital multi-function peripheral 1 starts the transmission program shown in the flowchart of FIG. 7. First, the CPU 11 sends a normal fax transmission to the LCD display unit 31. And a selection screen for selecting transmission using the polling function is displayed (step 301).
Next, the CPU 11 determines whether or not normal fax transmission has been selected on the above selection screen (step 302), and if it is determined that normal fax transmission has been selected, executes normal fax transmission (step 302). 303).

On the other hand, if it is determined in step 302 that transmission using the polling function has been selected, the CPU 1 determines whether or not a destination fax number has been input. Since the operation is the same as that of steps 101 to 109 in the flowchart, the description thereof is omitted.
As described above, if it is possible to select normal fax transmission and transmission using a polling function, confidential fax transmission can be easily performed only when necessary.
