PURPOSE:To prevent incongruity in an alarm from occurring by immediately stopping the generation of an intermittent periodical waveform when a prescribed state is detected, and stopping the generation of a following intermittent periodical waveform after completing the output of the final period of the intermittent periodical waveform when prescribed time by a timer elapses. CONSTITUTION:A means 8 to detect the state, for example, of the fitting state of a seat belt, etc., is provided, and when such state is detected, the generation of the intermittent periodical waveform is immediately stopped. On the contrary, when the timer 7 clocks the prescribed time and the generation of the intermittent periodical waveform is stopped in the middle way at a time when the prescribed time times out, the waveform is outputted until the final period of the intermittent periodical waveform is completed. Thereby, an appropriate alarm can be generated and the incongruity can be prevented from occurring. |
