ABSTRACT:
The communication apparatus is provided with a timer for time counting a predetermined time interval and in the case where a control signal was detected witin a predetermined time interval, the automatic reception is done in the facsimile mode and image information is received. In the case where the control signal could not be detected within the predetermined time interval, the communication is done in telephone mode and the voice-communication is performed. Further, with such a constitution, the facsimile mode and the telephone mode are automatically switched, thereby enabling the image reception or voice-communication to be executed in correspondence upon a communication apparatus on the distant side.
