Title: Facsimile equipment
Inventor: KATSUMATA MAIKO
IPC: H04N1/21
Filed: 1993-04-28
Abstract: PURPOSE:To efficiently perform transfer by starting the transfer after a file for which transfer standby time elapses is detected. CONSTITUTION:A transfer destination telephone number is read out and the transfer of a transfer standby file is started when a transfer mode is turned on by referring to a RAM 19 and the file for which the transfer start time to the RAM 19 elapses exists. When another transfer standby file exists, all the transfer standby files are transmitted sequentially in serial communication even when no transfer start time elapses. When all the transfer standby files are finished to transmit normally, transfer finished original images are erased from an image accumulation part 13, and a transfer operation is completed. In such a case, the transfer start time of each file set on the RAM 19, etc., is also erased. In such a way, since the transfer is started at the point of time when the file for which the prescribed transfer standby time elapses is detected, it is possible to prevent communication expenses from being consumed wastefully and to perform the transfer efficiently in which occupied time of transfer destination facsimile equipment can be extremely reduced.
