<P>PROBLEM TO BE SOLVED: To provide an electric appliance easily preventing damage to a driving part even when a counter electromotive force is generated in a motor in a state with no voltage supplied from a power source to the driving part. <P>SOLUTION: The electric appliance 101 is provided with a main body part 104, a cover member 103, an interlocking switch 105 and a diode for prevention of counter electromotive force 106. The main body part 140 is provided with a motor driving part 124 and power source wiring R1. The cover member 103 can take an open stance exposing an interior of the main body part 104 and a closed stance separating the interior of the main body part 104 from outside. The interlocking switch 105 is provided in the middle of the power source wiring R1 and is turned on when the cover member 103 is in the closed stance and turned off when the cover member 103 is in the open stance. The diode for prevention of counter electromotive force 106 is connected in parallel to the interlocking switch 105 and when the interlocking switch 105 is turned off, current is made to flow to power source wiring R1'' on the power source 121 side from power source wiring R1' of the motor driving part 124. <P>COPYRIGHT: (C)2008,JPO&INPIT |
