LASER MODULE, OPTICAL PICKUP DEVICE AND OPTICAL DISK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a laser module in which a position and a posture of a laser light source can be adjusted even in a narrow space, light intensity required for recording and reproducing information is secured and influence is hardly caused by a fluctuation in use temperature and to provide an optical pickup device and an optical disk device.

SOLUTION: The laser light source 52 is provided with a laser light source box lens adjustment member 55 and a laser light source shift member 56 so that a lead 51 passes through. An FPC 57 is soldered to the lead 51 so as to be fixed. The laser light source 52 and the laser light source camera movement adjustment member 55 are depressed by a depression spring 53. Thus, they are fixed between a pressure plate 54 and the laser light source shift member 56. The laser light source camera movement adjustment member 55 has a spherical surface with a light emitting point of the laser light source 52 as a center and it has a function of adjusting an inclination of the laser light source 52 with respect to an axial direction by turning the member with the light emitting point of the laser light source 52 as the center.
