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.
Claims5
A facsimile receiving apparatus comprising:
- first detecting means for detecting an establishment of a communications link between said receiving apparatus and distant apparatuses, including a transmitting facsimile apparatus;
- signal sending means for sending an image reception mode signal in response to the detecting result of said first detecting means;
- second detecting means detecting for a response signal which is sent by said transmitting facsimile apparatus in response to the image reception mode signal, the response signal including a signal representing an image transmission mode of the transmitting facsimile apparatus;
- operator calling means for generating a calling signal for an operator when said second detecting means does not detect the response signal from said transmitting facsimile apparatus within a predetermined period of time;
- and
- means for enabling facsimile information transfer from said transmitting facsimile to said receiver facsimile apparatus when said second detecting means detects the response signal within said predetermined period of time.
