<p>PURPOSE: To provide an inexpensive and electrical shock type burglary preventing device by using the output of a power source which generates a high voltage in electronic equipment for shock generation. CONSTITUTION: A microcomputer 7, when detecting the fact that a switch 3 is switched to the start-up side of a burglary preventing device and also, an ignition key is extracted, operates a high voltage circuit 5 after some delay time. Also, the microcomputer controls by switching relay switches 9, 10 so that the high voltage is applied to a conductive part 4 and no high voltage is applied to a fluorescent lamp 6. Adversely, when the ignition key is inserted to an ignition key cylinder 8, the microcomputer 7 stops the high voltage circuit 5, and also, controls the relay switches 9, 10 so that the conductive part 4 and the high voltage circuit 5 are cut off and also, the fluorescent lamp 6 is connected to the high voltage circuit 5. In this way, when the human body of a third party touches the conductive part 4 of an on-vehicle display 1 to steel it, shock by the high voltage is applied to the body, which excludes burglary, etc.</p> |
