Abstract

PURPOSE:To obtain a tasteful timepiece by selecting a melody at random and using it as a timecasting tone, through a random-number generating means at certain time, by storing plural kinds of melody data in a storage circuit. CONSTITUTION:A timepiece mechanism 1 outputs a time signal by a switch mechanism which couples with hands as an analog timepiece or by a carry signal, etc., as a digital timepiece. A control circuit 2 receives the time signal to specify the starting address of a data area for a melody to be used in a melody ROM3 stored with data of plural kinds of melody, and starts a tempo/sound length generating circuit 4 and a sound source device 5. In addition, a random-number generator 6 is provided. Consequently, a melody to be used at specified time is selected at random and the timepiece becomes tasteful.
