ABSTRACT:
Described is an optical equipment using a semiconductor light emitting device array which has light emitting points formed thereon at a high density and has highly reliability. The optical equipment according to the present invention features that it is equipped with a light emitting device array on which light emitting points LP have been arranged two-dimensionally, focusing means for focusing the light from the light emitting points, photo-detecting means which is disposed at the position where the light focused through the focusing means forms image formation points, and transferring means for transferring the image formation points relative to the photo-detecting means; said light-emitting device array being composed of a plurality of semiconductor chips and adjacent end surfaces of two semiconductor chips being bonded each other so as to have an inclination against the transferring direction.
