Claims

[Scope of utility model registration request]

An optical system in which a light-receiving element that receives the detection beam is mounted on a chassis equipped with an optical system that outputs a detection beam based on information recorded on an optical disk, with a light-receiving element base to which the light-receiving element is fixed interposed. This is a mounting structure for a light-receiving element of a type pickup, characterized in that the light-receiving element base is adhesively fixed to a chassis, and the light-receiving element and the chassis are sandwiched and tightened and fixed by a clamp member. Mounting structure of optical pickup photodetector.
