摘要:
A bar code scanner has a light-emitting element, a light-receiving element, an optical means for applying a light beam from the light-emitting element to a bar code area and for leading the light reflected from the bar code area to the light-receiving element, an electrical processing circuit, a sensor body for accommodating the light-emitting element, the light-receiving element and the optical means, a pair of split casing members for retaining the sensor body, an intermediate cap for connecting together the pair of split casing members, and a distal end cap adapted to be detachably retained by the intermediate cap in such a manner that a light incident and emergent portion of the sensor body alone is exposed. The bar code scanner is provided with a projection formed on an extending portion provided at one end of each of the split casing members and adapted to contact the side portion of the sensor body with flexibility so that the sensor body is movable. A retaining portion is formed on the inner surface of the intermediate cap, and an engaging portion is formed on the outer surface of each of the split casing members and adapted to engage with the retaining portion, whereby the retaining portion and the engaging portion are fitted to each other in such a manner that the extending portion deflects about the projection.

An optical coordinate input device comprises a number of light emitting elements and corresponding light detecting elements disposed in a plurality of linear arrays. A light ray selection member is provided such that only the light rays from the light emitting elements are detected by the light detecting elements. The light ray selection member is an optical semiconductor element light obstructing holder. The optical semiconductor elements have terminals projecting from the bottom surface of their main body which are fixed to a base and have a light emitting function or light detection function. In addition to these, a pair of mold bodies extending in the array direction of the optical semiconductor elements is combined, and this array of elements can be integrally fitted therein while being provided with a pressure portion elestically contacting the bottom surface of the main body of each element.

An optical coordinate data entry device mounted on the face of a display device. The entry device comprises an array of light-emitting devices, an array of light-receiving devices corresponding to the light-emitting devices, and a condenser lens member extending parallel to the arrays for directing the light beams coming from the light-emitting devices onto the light-receiving devices. A spacer acting also as a light-blocking member is formed integrally with the lens member.
