摘要 PROBLEM TO BE SOLVED: To provide a pickup device which can position a half mirror while performing fine adjustment of the mirror to a pickup frame. SOLUTION: This pickup device 1 can optically read the information recorded on a disk 3 set in a disk player and is provided with a pickup 11, an LD 13, a half mirror 15, a photodetector 17 and a pickup frame 19. The pickup 11 radiates light toward the disk 3 and receives the light that is reflected by the disk 3, and the LD 13 sends the light to the pickup 11. The mirror 15 reflects the light emitted from the LD 13 and sends the light to the pickup 11. The mirror 15 has a plate-like shape and the light sent from the pickup 11 can be transmitted through it.
