Abstract: An operation apparatus includes: an operation plate on which an operation surface performed by a pressing operation with an operation body; an assembly member assembled with the operation plate; a first elastic member opposite to the operation surface with respect to the operation plate, and between the operation plate and the assembly member to be elastically deformable by a pressing force applied by the operation body; a sensor detecting an elastic deformation changing amount of the first elastic member generated by the pressing operation; a pressing determinator determining whether the pressing operation is performed based on a detection value of the sensor; and a second elastic member between the operation plate and the assembly member to be elastically deformable with the first elastic member by the pressing force. The first and second elastic members are arranged to enable the pressing force applied serially.

Abstract: An operation apparatus includes: an operation plate having an operation surface performed by a pressing operation with an operation body; a vibrator including a movable yoke and a fixed yoke for generating a magnetic circuit for guiding a magnetic flux, and an exciting coil for generating the magnetic flux, and the vibrator vibrating the operation plate through a magnetic force generated by an electrical conduction on the exciting coil; a detector detecting a pressing amount by the pressing operation; a press determinator determining based on the pressing amount detected by the detector whether the pressing operation is performed; and a vibration controller for an electrical conduction on the exciting coil when the press determinator determines that the pressing operation is performed. The detector detects the pressing amount by detecting a change in an electrostatic capacitance generated between the movable yoke and the fixed yoke.

Abstract: A capacitive switch device includes an operation panel operated by a user with a touch operation, a film member provided along a surface of the operation panel on an opposite side from a surface operated with the touch operation, and an electrode portion forming a capacitor with a finger of the user and a wiring portion, both the electrode portion and the wiring portion being provided to the film member. The film member is bonded to the operation panel by a pressure-sensitive adhesive at a predetermined first portion of the film member and supported at a second portion of the film member different from the first portion by a supporting portion which allows the film member to move due to thermal expansion and thermal contraction in an in-plane direction of the film member.
