Abstract: An input device that inputs information corresponding to a change in pressure due to load includes: a first charge detection circuit that outputs a first detection signal corresponding to charges generated in a first piezoelectric sensor and a second piezoelectric sensor; and a switch circuit provided on a path through which the charges are transmitted from the first and second piezoelectric sensors to the first charge detection circuit. The first charge detection circuit alternately iterates a first period in which a first charge is input from a first positive electrode via the switch circuit and a second period in which a second charge is input from a second negative electrode via the switch circuit, reverses a sign of one of the first and second charges, combines a resulting charge with the other charge, and outputs the first detection signal corresponding to the amount of accumulation of the combined charge.

Abstract: An operation input device includes a resistance element to generate a capacitance between an operating medium and the resistance element in response to an approach of the operating medium to the resistance element, and a power source to supply electric charge to one end and the other end of the resistance element. A first electric unit measures a first electric charge transfer amount supplied to the one end of the resistance element in response to generation of the capacitance. A second unit measures a second electric charge transfer amount supplied to the other end of the resistance element in response to generation of the capacitance. A controller is connected to the first and second units, and detects a position of the operating medium in a direction perpendicular to a surface of the resistance element based on a sum of the first and second electric charge transfer amounts.

Abstract: A door handle includes a door handle case and an electrostatic sensor provided in the door handle case. The electrostatic sensor includes a detection electrode that is formed of a flat conductor plate, or that is formed on a surface of a flat substrate or within a flat substrate. The detection electrode includes a middle portion in a longitudinal direction of the detection electrode and includes peripheral portions proximal to both end portions of the detection electrode in the longitudinal direction. For a width of the detection electrode in a direction perpendicular to the longitudinal direction, each peripheral portion is wider than the middle portion, and the width of the detection electrode gradually increases toward each end portion in the longitudinal direction.

Abstract: An operation device includes a housing, an operation member, and a detector. The housing includes an electrically conductive portion on a surface thereof. The operation member is supported by the housing such that the operation member is movable in response to an operation by an operation body, and is configured to be capacitively coupled to the operation body and to the electrically conductive portion. The detector is configured to detect whether the operation body is in proximity to the operation member based on a change in capacitance at the electrically conductive portion.
