US Patent 7810109 Compact disc picker

A picker for compact discs is provided on a picker head and includes a finger which pivots relative to the picker head and will move from a retracted position within a guide that enters the opening in a compact disc to an outward extended position. When the finger is pivoted outwardly, a lug on the finger will engage the edge surface of the opening in the compact disc and urge the disc so the opposite side edge of the opening is urged against portions of the guide to securely grip and hold the disc and permit picking one disc at a time. A sensor is utilized for sensing the position of the disc relative to the guide and to provide a signal to an actuator that operates to cause the finger to move to its outwardly extended position.
