Normally, in operation, the time for polling transmission is determined in advance, and the facsimile apparatus on the polling transmission side is often set to a state in which image data to be transmitted can be transmitted by that time. .

However, in such an operation mode, when the transmission side facsimile apparatus is ready to transmit image data to be transmitted after a predetermined scheduled time for polling transmission (concentration), transmission is performed. However, there is a problem that the image data to be transmitted is not transmitted to the facsimile machine on the receiving side.

[0006]

In order to solve the above-mentioned problems, the solution means provided in the present invention is such that a communication terminal device on the transmitting side receives the transmission request from the communication terminal device on the receiving side, In a polling communication system for transmitting image data to a communication terminal device, the communication terminal device on the transmitting side is configured to transmit from the communication terminal device on the receiving side even when a predetermined time has elapsed after preparation for transmitting the image data. When the transmission request is not received, the transmission of the image data is started to the communication terminal device on the receiving side.

According to the above configuration, the communication terminal device on the transmitting side is ready to receive the image data, if the transmission request is not received from the communication terminal device on the receiving side even after a predetermined time elapses. Start transmitting image data to the communication terminal device on the side. Therefore, the communication terminal device on the transmitting side can reliably transmit the image data to the communication terminal device on the receiving side.

Then, in step S57, the control unit 53 controls the current time, which is time information transmitted from the clock unit 7, and the polling transmission timeout registered in the polling transmission timeout monitoring table 58 of the memory unit 52 shown in FIG. Start comparison with time. In addition, the control unit 53
Starts the comparison between the current time, which is the time information transmitted from the clock unit 7, and the polling transmission switching time registered in the polling transmission timeout monitoring table 58 of the memory unit 52 shown in FIG.

Then, the process proceeds to step S58, and the control unit 53
Determines whether the polling transmission time-out time has come, and in step S59, the control unit 53 determines whether the polling transmission switching time has come. If it is determined that the polling transmission time-out time or the polling transmission switching time has not come, the process proceeds to step S60, waits for an incoming call, and the steps from step S58 to step S60 are performed until the polling transmission timeout time or the polling transmission switching time comes. Repeat the process and wait for an incoming call. That is, the control unit 53 sets the current time and the polling transmission timeout time in the polling transmission timeout monitoring table 58 shown in FIG.
And the polling transmission switching time are compared to determine whether the polling transmission has started before the polling transmission time-out time and whether the polling transmission has started before the polling transmission switching time.

If the polling transmission time-out time has arrived without an incoming call, or if the polling transmission switching time has come, it is determined that a time-out has occurred and the process proceeds from step S58 or step S59 to step S69. In step S59, if it is determined that the polling transmission switching time has elapsed even if the polling transmission timeout has not occurred, the process proceeds to step S69.

As processing for proceeding from step S59 to step S69, for example, when 8 am is registered as the polling transmission switching time, in FIG. 17, the polling transmission originals 1 and 2 in the polling transmission waiting state are registered.
In Nos. 3 and 3, only the No. 1 polling transmission manuscript has become the polling transmission time-out and is the target for switching to the normal facsimile transmission. However, after 8 am, as shown in FIG. Even for the 2nd and 3rd polling transmission originals that have not reached, the switching from the polling transmission to the normal facsimile transmission is performed.

The steps S61 to S will be described below.
The process up to 73 is the same as the process from step S10 to step S22 of the first embodiment except step S66, and therefore the description is omitted except the process of step S66.

In step S66, the control unit 53 reads out the polling transmission document stored in the memory unit 52 in advance by the signal lines 16 and 17, and the signal lines 20 and 21 ,.
The data is transmitted to the receiving side facsimile apparatus 2 via the facsimile communication section 5 and the signal lines 37 and 38. In addition, the control unit 53
Is the current time and the polling transmission timeout registered in the polling transmission timeout monitoring table 58 shown in FIG. 17 in the memory unit 52, which is started when the polling transmission document is registered and the transmission preparation for the polling transmission document is completed. The comparison with the time is stopped, and the comparison between the current time and the polling transmission switching time registered in the polling transmission timeout monitoring table 58 of the memory unit 52 shown in FIG. 17 is stopped.

Further, the above step S70 shown in FIG.
The process of the facsimile device 50 on the transmission side shown in FIG. 22 performed in step S71 and the process of the facsimile device 2 on the reception side performed in response to the process are the same as the process shown in FIG. To do. 22. FIG. 22 is an explanatory diagram showing the signal system of the facsimile device on the polling transmission side and the facsimile device on the polling reception side according to the second embodiment.

As described above, in the second embodiment, the same effect as that of the first embodiment can be obtained, and the facsimile machine 50 on the transmitting side is the facsimile machine 2 on the receiving side.
When the time limit for receiving the polling transmission request from the device is set, and the time has passed in the polling transmission waiting state (the state in which the polling transmission request is not received from the facsimile device 2 on the receiving side), the normal facsimile By switching to transmission, the polling transmission document can be transmitted by the time the facsimile apparatus 2 on the reception side requires it.
