ABSTRACT:
A pair of rollers spaced at a predetermined interval are arranged in the bottom part of a facsimile machine. When the facsimile machine is manually moved on an original document while pushed against it, the rollers rotate. Detecting the rotation of the rollers, an encoder performs power on/off operations, i.e., enables/disables the supply of an electric power from a compact power supply unit, in accordance with the start/stop of the roller rotation. Upon the power on, an image sensor starts to read the document. An image signal produced by the image sensor is processed by a signal control unit, and then modulated by a G3 modem. The modulated signal is sent out to a telephone line via a network control board.
