The operation display section 4 includes a transmission button and a reception chain (not shown).

It is equipped with an operation button for inputting a destination telephone number, etc., and a display section for displaying input data, etc.

The recording unit 6 has a printer that prints out image data. The transmission control unit 7 has a function of controlling transmission and reception of image data. The modem 8 has a function 9 for modulating and demodulating image data, a communication training function, and a function for controlling the transmission speed.

Network Control Unit
(hereinafter referred to as NCU) 9 has a function of controlling connection and disconnection of the circuit switching network. The automatic transmission unit 10 has a function of automatically calling a receiving station according to a command from the main control unit 3.

With such a configuration and function, an operator inserts the original document 1 to be sent into the device and inputs the destination telephone number from the operation display section 4. Then, the receiving station is called, and when the receiving station is ready for reception, the document 1 is read by the image sensor, converted to image data, sent to the main control unit 3, converted into binary data, compressed, and converted into image data. The image data is stored in the memory 5a, and is modulated by the modem 8 for each page under the control of the transmission control section 7, and sent out to the line for the receiving station via the NCU 9.

In the case of automatic transmission, the image data memory 5a
At a predetermined time, the automatic transmitter 10 calls the receiving station and transmits the image data stored in the image data.

At the receiving station (here, the operation of the receiving station will be explained using the receiving function shown in FIG. 4), the received image data is expanded and sent to the recording section 6, where it is recorded on recording paper.

In the case of transmission by polling, the NCU 9 detects polling from a reserved receiving station, that is, an incoming call, turns on the device power, and transmits the image data stored in the image data memory 5a. When the transmission to the receiving station that has made the polling reservation is completed, the image data stored in the image data memory 5a is deleted. Alternatively, even if polling reservations remain, they will be deleted after a predetermined period of time, for example 24 hours, has elapsed. There is also a method in which a FAX service provider verifies polling from a receiving station with a predetermined password and then provides transmission service.

[Problem that the invention seeks to solve]

According to the above conventional method, polling is performed corresponding to at least one reserved receiving station, and image data is deleted when transmission to the reserved receiving station is completed.
Alternatively, even if a reservation remains, it will be deleted after a predetermined period of time has passed.

However, information services, such as travel information.

When providing information such as new product introductions, department store advertisements, and event information, the same information, that is, image data, can be sent from an unspecified number of fax machines without a reservation, and the information There is a problem in that there is a need for a method to provide repeat transmission services.

[Means for solving problems]
