  • Publication number: 20120033231
    Abstract: An optical position detection apparatus detects the position of a target object based on the result of the light reception through a light receiving unit when a light source is turned on. In a front-side housing portion of a housing of an optical unit, a reflection unit for generating a default light that makes the default light be incident to the light receiving unit is configured even in a state where a target object is not present. Accordingly, the initial setting of the relationship between a drive current in the light source unit and a light intensity in the light receiving unit can be appropriately performed based on the result of receiving the default light.
