<P>PROBLEM TO BE SOLVED: To provide an electrical apparatus capable of easily preventing breakage of a drive part, even if a counter electromotive force is generated in a motor. <P>SOLUTION: The body part 104 of the electrical apparatus includes a cover member, an interlock switch 105, a 24 V power supply 121, a 5 V power supply 122, power supply wirings R1, R2, a motor drive part 124 and a motor 125. The interlock switch 105 is provided on the way of the power supply wire R1. When the cover member is in a closed attitude, a power supply wiring R1" on a motor drive part 124 side is connected to a power supply wiring R1' on a 24 V power supply 121 side. When the cover member is in an open attitude, the power supply wiring R1" is connected to a power supply wiring R2' on a 5 V power supply 122 side. According to such a configuration, a counter electromotive force generated at the motor 125 with the cover member in an open posture runs through the 5 V power supply 122. <P>COPYRIGHT: (C)2010,JPO&INPIT |
