Patent ID: 8736562

Claim:
An electrical device comprising: an input member that comprises: a plurality of conductive elastic bodies including first and second bodies; an operation plate that has an operation plane and that has plurality of conductive elastic bodies on a rear surface side of the operation plane; a base plate including a plurality of pair electrodes that include first and second pair electrodes, each of the plurality of pair electrodes being provided by a pair of electrodes without contacting each other at positions opposite to the plurality of conductive elastic bodies; and a plurality of protruding parts respectively protruding from the plurality of conductive elastic bodies toward the base plate are aligned in a predetermined direction, the plurality of protruding parts including first and second parts that respectively correspond to the first and second bodies; and a control unit that is provided inside or outside the input member, wherein the control unit comprises: a measurement unit that measures a measurement value of an electrical resistance value, a voltage value, or a current value, which is varied in accordance with a degree of electrical contact between each of the first and second pair electrodes of the plurality of pair electrodes through the first and second bodies, respectively, at predetermined time intervals; a position specifying unit that specifies at least an operation position based on the measurement value that is measured by the measurement unit or a numerical value that corresponds to the measurement value; and an operation type specifying unit that specifies either a slide operation that corresponds to moving. an operation position with continuous touching of the operation plate or a touch operation that corresponds to touching a desired position of the operation plate, based on a relationship between a measurement time and the operation position that is specified by the position specifying unit, wherein the first and second pair electrodes are located adjacent to each other, when a change of the measurement value is detected between each of the first and second pair electrodes within the predetermined time, the operation type specifying unit specifies that the slide operation is performed, and when a chance of the measurement value is detected between only one of the first and second pair electrodes within the predetermined time, the operation type specifying unit specifies that the touch operation is performed.
