Patent ID: 8186471

Claim:
A control apparatus for controlling a high voltage power supply circuit to supply power from a high voltage power supply to an electronic device, said control apparatus comprising: a supply switching unit for switching supply of power on and off from said high voltage power supply to said electronic device; a switching command unit for commanding said supply switching unit to switch supply of power from said high voltage power supply; a collision detecting unit for detecting a collision from outside said electronic device; and a collision determining unit for determining a collision with said electronic device on the basis of at least detection by said collision detecting unit; wherein said collision detecting unit includes a pressure sensitive sensor for detecting a load from outside said electronic device and conducting power, and a bracket formed with a steel plate, covering a periphery of said pressure sensitive sensor, for fixing said pressure sensitive sensor to a surface of a case to house said electronic device; said pressure sensitive sensor includes a pair of electrodes facing each other at a predetermined interval so as to contact each other and conduct power when receiving an excessive load; said collision determining unit determines a collision by contact and conduction between said electrodes of said pressure sensitive sensor caused by a load through said bracket; and said switching command unit commands said supply switching unit to stop supply of power from said high voltage power supply on the basis of collision determination by said collision determining unit.
