Mobile facsimile telecommunications system capable of automatically off-hooking a facsimile device

摘要

A mobile facsimile telecommunications system utilizes an automobile telephone system as a transmission path. In one aspect, this system utilizes an adaptor which can place the facsimile device under an off-hook condition without using an ordinary telephone set additionarily provided to compensate for defects of a portable-type facsimile device having no dialing function, thereby achieving its simplification of system construction as well as the reduction of telephone charges. In another aspect, this system utilizes an automatic response function, a polling transmission function using a given default value, and an automatic off-hook function specified by an operator after conversation, thereby rendering the manipulation for facsimile communication simple.
