Abstract
The objective is to prevent erroneous operation of an optical sensor while removing restrictions on the degree of freedom of design. In a handgun-shaped controller comprising a lens for focusing light that is incident on a muzzle and an optical sensorfor detecting the thus-focused light, a light-proof caseis provided to cover the lens and optical sensor in such a manner that external light other that from a muzzle is not incident thereon. The light-proof case covers the entire surface of the optical sensor and the portion of the board on which the optical sensor is mounted. Cut-out portionsA andB for through-holes for signal terminalsare provided in a connection portion between partsA andB that form the light-proof case. A protuberant portion is provided on the connection portion of one partA and a fit portion thereof is provided in the connection of another partB. A protuberant portion is provided so as to deform when a boardis pressed into slitsA andB, sealing the gaps between the slits and the board. The configuration could be such that the entirety of the board is covered by the light-proof case and the optical sensor is attached directly within the light-proof case.
