Abstract: The input device of the present invention includes: a base having a slide surface; a movable body slidable on the slide surface; a light-emitting element for emitting light; a reflective portion which is provided for the movable body and has a reflective surface for reflecting the light emitted by the light-emitting element; and a plurality of light-receiving elements for receiving the light reflected by the reflective portion.

Abstract: The input device which includes a reflection type optical sensor having light emitting means and light receiving means; an operation section disposed facing the optical sensor, the operation section being tilted when a load is applied thereto; and output means for detecting a tilt status of the operation section based on signals from the light receiving means and outputting detected results to a computer body as positional information.

Abstract: An optical sensor includes a sensor section provided in a secured manner and including a light emitting element and a light receiving element located opposed to the light emitting element; and a reflective body connected to an operation section and movable with respect to the sensor section. The reflective body is a concave mirror for guiding light from the light emitting element to the light receiving element.

Abstract: A photoreflective detector includes a light emitting element; and a light receiving element located so as to receive light emitted from the light emitting element and reflected by an object. The light emitting element and the light receiving element are located to have different distances from the object so as to avoid direct incidence of the light emitted by the light emitting element on the light receiving element.
