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

A facsimile transmission control method, comprising the steps of:

• establishing a transmission line between a transmitter and a receiver;
• implementing a predetermined transmission control procedure between said transmitter and said receiver to thereby establish parameters necessary for transmission of data between said transmitter and said receiver;
• and
• reading an original to produce image data and storing said image data for transmission while at the same time monitoring the amount of image data stored for transmission and also monitoring a timer, wherein, if said amount of image data stored for transmission has reached a predetermined amount before said timer has reached a predetermined time, said amount of image data stored for transmission is formed into a frame of data, which is then transmitted from said transmitter to said receiver, whereas, if said timer has reached said predetermined time before said amount of image data stored for transmission has reached said predetermined amount, then said amount of image data stored for transmission is formed into a frame of data, which is then transmitted from said transmitter to said receiver.
