<p>The present invention discloses a disk selecting apparatus comprising a casing, a circular plate, two step motors and a controlling circuit. On said circular plate, there is provided with storage grooves for storing optical disks, counting teeth each corresponding to one storage groove and a reset post which is arranged at original position of the circular plate. A reset sensor for detecting the reset post and a positioning sensor for detecting the counting teeth are mounted on said casing. There is a passage opening for the optical disks on a side wall of the casing, a roller for passage of optical disk is provided corresponding to said passage opening, and a sensor for detecting passage of the optical disk is mounted on the passage opening. Based on the information detected by the respective sensors, the controlling circuit causes one of said two step motors to rotate the circular plate and the other one to rotate the roller in two directions. Also, the other motor cause a cam mechanism for pushing the optical disks in the storage grooves of the circular to rotate while the roller is rotated by the other motor. The disk selecting apparatus of the present invention has the following functions: storing of optical disks, managing of optical disks and managing of data, etc., thereby achieving automatic storing and selecting of optical disks.</p> |
