Abstract:
1. A disk transfer mechanism for a disk inspection apparatus successively inspecting front and back faces of a disk including a disk inverting mechanism for inverting the front and back faces of the disk comprising: a first spindle and a second spindle which are set at first initial position and at a second initial position respectively which are on a straight alignment line on which the first initial position, inspection positions for disk inspection at which the spindles are set and the second initial position are aligned, and which are positioned alternatively at the respective inspection positions, a spindle moving mechanism which moves the first spindle and the second spindle respectively along the alignment line toward the respective inspection positions, and a control unit through control of the spindle moving mechanism which moves the first spindle to the inspection position, after completing an inspection of a disk fitted to the first spindle, moves the first spindle from the own inspection position to the first initial position as well as moves the second spindle to the own inspection position, and after completing an inspection of a disk fitted to the second spindle, moves the second spindle from the own inspection position to the second initial position as well as moves the first spindle to the own inspection position, wherein the disk fitted to the second spindle is the one that is detached from the first spindle after completing the inspection and inverted by the disk inverting mechanism.
