Facsimile machine

Abstract

A facsimile machine which includes a telephone conversation function that can securely shift the facsimile communication mode to a telephone conversation mode after facsimile communication, even if an error occurs during facsimile communication. This is accomplished without using a telephone conversation reservation function. At a point where after facsimile communication is started, facsimile communication may be stopped after the transmission of predetermined signals between the calling party side facsimile machine and the receiving party side facsimile machine, or due to error. In the case where a communication error occurs because of paper jamming, the main controller keeps occupying the communication line occupied by the line controller, and a signal sound on the occupied communication line is externally emitted by the speaker. When the calling party recognizes that the receiving party requests a call, which is based on the signal sound transmitted from the communication line and externally emitted by the speaker the calling party lifts the handset. The lifting of the handset is then detected by the hook switch. After detection by the hook switch, the main controller controls the line controller to enable conversation with the receiving party side facsimile machine via the handset.
