Zusammenfassung: | PURPOSE:To prevent static electricity from entering an internal circuit through an operating electronic part or the like even if it is a structure that the static electricity easily enters from a part of an operation member in an operation device for an electronic equipment. CONSTITUTION:Spaces A and B are formed around a pressing part 8b situated in front of a circuit board 3, and are set so that static electricity easily directly enters the circuit board 3 from the periphery of an operation button 9. Here, a tact switch 5 and a connector pin or the like are covered with an insulating sheet 21, and only an earth pin 7a of the connector pin 7 is exposed from a hole 21e of this insulating sheet 21. Thereby, the static electricity is not transmitted to the tact switch 5 or the like, and is actively introduced to the connector pin 7, and is released to an earth part. |
