Optical scanning device having a reflection section and photodetecting section integrally formed on a moving part of an optical scanning section

摘要

An optical scanning device has a light source. A condenser lens gathers rays of emitted light from the light source. A reflecting section reflects the light gathered by the condenser lens. An optical scanning section includes of a fixed section and a moving section and causes the light reflected by the reflecting section to scan an object to be scanned. A photodetecting section receives and detects the light returned from the object scanned by the optical scanning section. The reflecting section and the photodetecting section are integrally formed on the moving section of the optical scanning section.
