The facsimile communication apparatus according to claim 1, wherein the waiting controller comprises:determination means for determining whether or not the receiving side facsimile machine can wait in a data reception mode if the desirable amount of image data has not been stored in the memory at the time of receipt of the data-receiving control signal; waiting means for waiting for further storage of image data until the desirable amount of image data is stored in the memory if the determination means determines that the receiving side facsimile machine can wait in the data reception mode; and wait control signal transistor for transmitting the wait control signal to the receiving side facsimile machine if the determination means determines that the receiving side facsimile machine can not wait in the data acceptable state.
- 3. The facsimile communication apparatus according to claim 2, further comprising calculation means for calculating the desirable amount of image data stored in the memory by multiplying the transmission rate of the image data determined by negotiation between the transmission side facsimile machine and the receiving side facsimile machine by a predetermined time stored in advance.
- 4. The facsimile communication apparatus according to claim 2, further comprising calculation means for calculating the desirable amount of image data stored in the memory by multiplying the communication rate determined by negotiation between the transmission side facsimile machine and the receiving side facsimile machine by a predetermined time stored in advance.

- 8. The facsimile communication apparatus according to claim 1, wherein the transmission side facsimile machine and the receiving side facsimile machine are G3 facsimile machines categorized based on a T.30 Recommendation, the data-receiving control signal comprises a data-receivable state confirmation signal CFR according to the T.30 Recommendation, and the wait control signal comprises a transmission site identification signal TSI according to the T.30 Recommendation.
- 9. A program recording unit storing a program for controlling a facsimile communication apparatus that receives image data from a transmission side facsimile machine via a data communication network, temporarily stores the received image data in a memory, and transmits the image data to a receiving side facsimile machine, said program recording unit comprising:means for causing the facsimile communication apparatus to call the receiving side facsimile machine based on a request for connection to the receiving side facsimile machine received from the data communication network; means for causing the facsimile communication apparatus to temporarily store the image data transmitted from the transmission side facsimile machine via the data communication network in the memory; means for causing the facsimile communication apparatus to start transmitting the image data to the receiving side facsimile machine when the facsimile communication apparatus receives a data-receiving control signal that represents the acceptability of image data of the receiving side facsimile machine, provided that a desirable amount of image data is stored in the memory at the time of receipt of the data-receiving control signal; and waiting controller for causing the facsimile communication apparatus to transmit a prescribed wait control signal to the receiving side facsimile machine in order to have the receiving side facsimile machine stand by if the desirable amount of image data has not been stored in the memory at the time of receipt of the receiving control signal representing the acceptability of the image data from the receiving side facsimile machine.
- 10. The program recording unit according to claim 9, wherein the waiting controller comprises:determination means for determining whether or not the receiving side facsimile machine can wait in a data reception mode if the desirable amount of image data has not been stored in the memory at the time of receipt of the data-receiving control signal; waiting means for waiting for further storage of image data until the desirable amount of image data is stored in the memory if the determination means determines that the receiving side facsimile machine can wait in the data acceptable state; and wait control signal transmitter for transmitting the wait control signal to the receiving side facsimile machine if the determination means determines that the receiving side facsimile machine cannot wait in the data reception mode.
- 11. The program recording unit according to claim 10, further comprising calculation means for calculating the desirable amount of image data stored in the memory by multiplying the transmission rate of the image data determined by negotiation between the transmission side facsimile machine and the receiving side facsimile machine by a predetermined time stored in advance.
- 12. The program recording unit according to claim 10, further comprising calculation means for calculating the desirable amount of image data stored in the memory by multiplying the communication rate determined by negotiation between the transmission side facsimile machine and the receiving side facsimile machine by a predetermined time stored in advance.
- 13.
