Abstract

PURPOSE:To prevent the occurrence of a traffic accident by operating a switch by detecting the driving state of a car, and disabling origination from a car telephone set when the speed of the car exceeds a prescribed one. CONSTITUTION:A driving detector 1 detects the driving speed of a car, etc., to monitor whether the car is running at a certain speed and below all the time. When the car is in some driving state, e.g. stop state, the detector 1 sends a control signal to control a switch 2. The switch 2 connects a dial signal generator 3 to the main device 4 of the car telephone set to enable origination. Consequently, only at least dialing operation shoud be done in the stop state, so the dialing operaton having the high possibility of the occurrence of a traffic accident is never performed while the car is running, so that origination is achieved very safely.
