ABSTRACT:
A memory-equipped facsimile machine wherein image data read by a scanner device is once stored in a memory and is then retrieved therefrom for transmission to another facsimile via a telephone line. In order to disperse working load imposed to a microcomputer and to increase a transmission speed, the reading of the image on a document is performed during call estabishing and message procedure phases as opposed to reading during a beginning-of-message procedure phase. The microcomputer instructs the scanner device to read the document in the call estabishing procedure phase and then to stop reading the document in the beginning-of-message procedure phase. The microcomputer further instructs the scanner device to resume reading the document in the message procedure phase C.
