OPTICAL DISC DRIVE FOR ORGAN

摘要

An electronic organ of a type that utilizes an optical disc record to generate sounds, which is constructed to allow rapid and easy installation and removal of disc records, including an organ housing with a doorway through which disc records can be installed and removed and a spindle for projecting through the central hole of the disc record to locate it while it revolves. The doorway opens to a pan with side walls and an end wall that are spaced from the spindle by distances slightly larger than the radius of the disc record, so that a record pushed in until it hits the rear wall and then released will automatically fall onto the tapered spindle. A door which can cover the doorway, raises a record lifting member when the door is open to guide an inserted disc over the top of the spindle, and then lowers the record lifting member when the door is closed to allow the disc to fall onto the spindle. The disc is driven by a drive wheel which rotates on a movable axle, and a link coupled to the door deflects the axle when the door is opened to move the drive wheel away from a disc record. The movable axle also operates an on-off switch.
