Abstract: An optical input device has a display screen, a portion of the display screen being shielded from light by an operating member to implement input processing based on a plurality of input modes. The input device includes an input detection unit including a display unit that displays predetermined input information, and a control unit. The input detection unit detects an area and/or brightness of a light-shielded portion formed on the display screen by the operating member by approaching the display unit. The control unit provides display control of the display unit and input control on the basis of the detected area and/or brightness. The control unit compares the detected area and/or brightness with a predetermined threshold value to select a desired input mode from among the plurality of input modes.

Abstract: An input device inputs information by a slide operation depending on an operation body. The device contains a housing having an operation surface, a detection unit that is provided in the housing and includes an electrostatic capacitance sheet member which detects a slide position of the operation body to output a position detection signal, and an operation unit that covers an entire surface of the detection unit and is slide-operated along the operation surface of the housing. The operation unit has a convex shape which becomes thicker along a sliding direction from one direction of the operation surface of the housing and also which becomes thinner toward the other direction of the operation surface thereof. The electrostatic capacitance sheet member includes a switch portion that is switched by a press-in operation of the operation body to the operation unit.

Abstract: An input device that inputs information by a slide operation depending on an operation body contains a housing including an operation surface, a detection unit that is provided in the housing and detects a slide position inputted by a slide operation depending on the operation body, and an operation unit that covers at least a portion of the detection unit and is slide-operated along the operation surface of the housing. The operation unit has a convex shape which becomes thicker along the sliding direction from one portion of the operation surface of the housing and also which becomes thinner toward the other portion of the operation surface thereof.
