<p>PURPOSE:To detect the presence of a body to be detected when an automobile is re-started by providing an alarm storage means which stores the occurence of an alarm when the automobile is stopped at a time when the alarm is issued due to the presence of the body to be detected, and an operation detecting means, etc. CONSTITUTION:When the automobile is re-driven, a key switch is turned on, and the body detector for automobile is re-started. Such re-start is detected with a re-start detection circuit 16, and a detection signal is inputted to an AND circuit 18 as a HI signal. At this time, since an alarm memory circuit 17 already outputs the HI signal to the circuit 18, the output of the circuit 18 goes to the HI signal, and the alarm is issued from an alarm 8 via an OR circuit 11. After that, when the body starts to move from such state, a discriminator 10 commands the occurrence of the alarm when the body approaches the detecting range of a sensor 3. When a speed sensor 12 detects the travel of the automobile, the output of a stoppage detection circuit 13 is sent from the HI signal to the alarm memory circuit 17 via a LO circuit 15, then, storage is cancelled.</p> |
