特徴とするデイスク検出機構。 In a disk detection mechanism that detects the presence or absence of the disk on a shelf that stores disks using a reflective optical sensor, the light emitted from the reflective optical sensor is transmitted to a corner reflex formed by a side surface of the shelf and one side of the disk. A disk detection mechanism characterized by ejecting light toward one side of the rector.
