<P>PROBLEM TO BE SOLVED: To prevent the erroneous operation of a switch part. <P>SOLUTION: An operation part 103 is pressed by an external object. A fixed contact and a movable contact part 102 formed on a substrate 101 is pressed by the operation part 103 so as to perform switching operation of a switch. An electrostatic sensor part 104 is stacked on the substrate 101 and the movable contact part 102, and capacitance changes corresponding to an area of a portion to which the external object is located closer than a predetermined distance. A case 105 houses the substrate 101, the movable contact part 102, the operation part 103 and the electrostatic sensor part 104. The case 105 also has a recess 112 into which the external object to press the operation part 103 enters, and restricts the movement in a pressing direction of the external object having a size too large to enter the recess 112. A control unit 108 starts a predetermined operation based on the switching operation of the switch by a switch part input determination unit 107 and a result of detection by the electrostatic sensor part 104 on the changes in capacitance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
