Claims

[Scope of utility model registration request]

In the case where an optical system including a diffraction grating that diffraction-divides a laser beam from a laser light source and an objective lens that focuses the laser beam onto an optical recording medium is housed in a housing, the diffraction grating is screwed through the housing. What is claimed is: 1. An optical pickup device, characterized in that the optical pickup device is supported by an elastic support member fixed within a housing by a screw member so as to be swingable in a direction parallel to an optical recording medium.
