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.

Position indication device, and information storage medium

An objective is to provide a position pointing device, a program and a method for detecting the position pointing device which relates to a device pointing a position on a display screen and which can discriminate a scan mode of a display device and obtain information of pointed position by performing a processing corresponding to the discriminated scan mode. A photosensor ( ) provided in the position pointing device detects a scanning beam from a display device ( ) and generates a light detection signal. A scan mode discriminating section ( ) judges that a scan mode in the display device is not a standard scan mode type, but a multi-density scan type if a frequency component of the light detection signal includes a frequency component of a horizontal synchronous signal in a multi-density scan type display device.
