<p>PROBLEM TO BE SOLVED: To provide a malfunction prevention device that can prevent a malfunction by performing the control of keeping a controlled object off on detecting a negative voltage or positive voltage due to an inflow of static electricity.SOLUTION: When a first detection section 132 or a second detection section 133 is in an operative state, an output section 134 outputs a control signal for controlling off a controlled object to prevent a malfunction to a control terminal of the controlled object. Specifically, when an electrostatic detection section 131 detects a negative voltage or positive voltage due to an inflow of static electricity, either of the first detection section 132 and the second detection section 133 starts up to hold the other in the operative state, and the output section 134 outputs a low level control signal for controlling off the controlled object, so that the controlled object is controlled off to prevent a malfunction.</p> |
