ABSTRACT:
An image transmission apparatus is provided which includes a main unit and a sub-unit. The sub-unit has a facsimile function, and communicates with the main unit by radio. The main unit is connected to a facsimile machine using a telephone line, and operates in a radio transmission mode and a facsimile mode. The radio transmission mode is to transmit a facsimile signal together with an operation procedure signal transmitted from the facsimile machine to the sub-unit, and transmit an operation procedure signal sent from the sub-unit to the facsimile machine through the telephone line. The facsimile mode is to establish facsimile communication with the facsimile machine instead of the sub-unit when a level of the field strength of a radio signal from the sub-unit becomes smaller than a preselected level.
