Abstract
A disc music box for playing a melody, which comprises a disc (3) having a plurality of engaging parts (4, 40), a motor (M) for rotating the disc, and star wheels (12) guided and rotated by the engaging parts of the rotating disc for plucking music box petals (17a), wherein control information for controlling other instruments to be operated in association with the play of the music box is recorded at desired portions on the disc excepting portions where the engaging parts are disposed on the disc. An information disc (101) has both playing and control information and is driven to rotate at a predetermined speed. A tricky timepiece comprises a disc music box instrument (120) to which a music box disc (101) is attached and a tricky device (150) interconnected with the disc music box instrument to move puppets (151), thereby providing tricky performance. The term "tricky" is defined as mechanized movements designed to amuse or impress.
