Facsimile transmission control method in which a frame of stored image data is transmitted when either a predetermined time has elapsed or a predetermined amount of image data has been stored

摘要

A digital facsimile communication control method includes a step of selectively determining a data communication mode between a digital circuit switching mode and a packet switching mode. When the digital circuit switching mode has been selected, while optically reading an original to be transmitted, the amount of data stored for transmission is checked and also the time is checked. And, if the amount of data stored for transmission has reached a predetermined amount before the time has reached a predetermined time, the amount of data stored for transmission is formed into a frame of data, which is then transmitted. On the other hand, if the time has reached the predetermined time before the amount of data stored for transmission has reached the predetermined amount, an amount of data which has so far been stored is formed into a frame of data, which is then transmitted.
