<p>PURPOSE:To synchronize the operation of an ornamental body and the musical performance melody by controlling the ornamental body and the musical performance melody by a first and a second timer signals based on a signal reference signal. CONSTITUTION:A master timepiece timer 2 generates a second timer signal T2 at a fixed time before a prescribed time, a control signal generating circuit 12 outputs a melody name signal A and a melody selecting signal B in response to the signal T2, and a CD desk 10 turns on a power source by the signal T2, and selects a musical performance melody designated by the signals A, B from a CD. In such a state, when a prescribed time comes, the master timepiece timer 2 generates a first timer signal T1, and simultaneously, the circuit 12 also generates a first timer signal T1, and simultaneously, the circuit 12 also generates a start signal C. In this case, an ornamental body driving control circuit 8 inputs the signal T1 and allows an ornamental body 6 to start its operation by applying a signal thereto, and the CD deck 10 allows a sound generating circuit 14 to generate a musical performance melody in accordance with the signal C, and stops it in accordance with an end signal D from the circuit 12. In this case, since the signals T1, T2 and C are signals based on a single reference signal phi, the operation of the ornamental body and the musical performance melody are synchronized, it is unnecessary to execute the adjustment at every musical performance melody, and the musical performance can be executed by selecting that which is designated from many melodies.</p> |
