絶えず変動するからである。Next, the transmitting side transmits the front side image in the continuous mode. During this time, the receiving side stores the received front side image in the image memory or stocks it in the intermediate tray in a state where one side is printed, and receives the front side image when the back side image is received. Is printed so that the back side image comes on the back side of the image, and the processing for the total number of sheets is completed. After transmitting the back side image, the transmitting side transmits EOM, and the receiving side returns DIS to determine the number of transmission units in the next continuous mode transmission. This is because the free space in the image memory and the remaining number of sheets in the intermediate tray constantly change during the receiving process.

Next, the response of the receiving side to the SUB signal or DCS is detected (step 8), and in the case of FTT (training failure signal), the original SUB signal and DCS are retransmitted, and
In the case of NV, the SUB signal and the DCS are retransmitted with the number of transmission units reduced by N as appropriate (step 9). Response is DI
In the case of S, it is determined that transmission in the continuous mode is impossible, and the process proceeds from step 3 to the transmission in the alternate mode. In the case of CFR, it is assumed that transmission in the continuous mode in units of the transmission unit number is confirmed (step 10). ).

戻る。When the CFR is received in step 10, the front side images of the transmission unit number are continuously transmitted, and then the back side images such as the transmission unit number are continuously transmitted (step 11, step 11).
12), check for the presence or absence of untransmitted images (step 1)
3) If not, end the communication. If there is an untransmitted image, it is determined in step 14 whether or not to continue the transmission. If it is to be continued, an EOM is transmitted in step 15 and the process returns to step 2 from the connector B, and the next transmission in the continuous mode is performed. The process proceeds to the confirmation of the propriety or the transmission unit number. The reason for returning to step 2 by sending the EOM is that printing is delayed with respect to reception in the continuous mode, the memory capacity is insufficient, or the number of remaining sheets in the intermediate tray has been reduced to less than the previous transmission unit number for some reason. In this case, the error is prevented from occurring. If the transmission is not to be continued, the line is disconnected and after waiting for a predetermined time in step 16, the flow returns to step 1 from the connector A.

へ戻る。FIG. 4 shows processing on the receiving side when a front surface image is stored in the image memory. In step 21, a call is received from the transmission side. Since the facsimile apparatus of the embodiment can receive in the continuous mode, in step 22, both-sided reception, continuous mode reception, and alternate mode reception are set to be possible, DIS is transmitted in step 23, and SUB signal is transmitted in step 24. The DCS is received, and in step 25, it is checked whether or not the alternate mode is designated. If the alternate mode is set, the image is alternately received in the order of the front surface and the back surface, and double-sided printing is performed each time (step 26). In the case of the continuous mode, it is checked in step 27 whether or not there is free memory for the number of transmission units in the image memory.
It is checked whether it is less than a page, and if it is less than two pages, it cannot be received in the continuous mode. Therefore, the duplex reception in the alternate mode is set, and the DIS is retransmitted.

め、結合子Ｂからステップ２４に戻る。If the number of transmission units is insufficient but there is free memory for two pages or more, the FNV for the SUB signal is transmitted in step 30. In this case, the possible number of transmission units is stored in the additional information of the FNV. Alternatively, as shown in FIG. 3, a new transmission unit number may be proposed by the determination of the transmission side as shown in FIG. In this case, too, the connector B returns to step 24 because it is necessary to confirm the number of transmission units and the like.

間で取り決める。FIG. 5 shows the processing on the receiving side when the front side image is printed on one side and stored in the intermediate tray. The same steps as those in FIG. 4 are denoted by the same step numbers. Step 25
If it is determined in step 37 that the mode is the continuous mode, it is checked in step 37 whether or not the free space (number of sheets accommodated) of the intermediate tray is equal to the number of transmission units.
In step 9, the DIS indicating that the mode is the alternate mode only is retransmitted, and the process returns to step 24 from the connector B. If the number of empty trays is not enough for the number of transmission units, but more than one,
When the value is 0, the FNV for the SUB signal is transmitted, and the process returns to step 24 from the connector B to determine the number of receivable transmission units with the transmitting side.

プ４５）。If the intermediate tray has the capacity corresponding to the number of transmission units, the CFR is sent out in step 41, and
In step 2, the front side images corresponding to the transmission unit number are received, printed on one side, and stored in the intermediate tray. In steps 43 and 44, the back side image is printed on the paper on the single side printed intermediate tray until all the back side images are received. Output. When all the back pages are received, if the EOM is received, the process returns to step 22 from the connector A, and otherwise, the process ends (step 45).

Decrease to the value. Further, if the front side image and the back side image are transmitted and there is still an untransmitted image, the process returns from EOM to step 22 to determine the number of transmission units again.
