Abstract

PURPOSE:To send a still picture from a remote place by connecting an external telephone set to an external telephone set connection terminal provided at the still picture transmitting video telephone set and issuing a picture sending command when a loop-off during a prescribed time is detected. CONSTITUTION:The selection of a transmitting opponent is executed by dialing an external telephone set 15. A line detecting part 17 detects a polarity inversion due to the loop-on of a circuit and the response of the opponent, and gives it to a CPU 13. Even when the CPU 13 detects the loop-off due to a dialing or a hooking, for example, when the time is 30-50ms, the CPU 13 does not judge that it is a calling completion, but operates a transmitting button 6, and sends out the still picture to a telephone line 1. Even during the call by an incoming call from the opponent, when the CPU 13 detects the loop-off of 30-500ms, it goes to be a picture sending condition. Thus, the picture can be sent even from the external telephone set in the remote place.
