Abstract
PURPOSE: To generate selectively plural melodies as alarm by providing a storage unit for melody data, a control circuit to read melody data selected by a selection circuit from the storage unit, and a time set unit.
CONSTITUTION: A selection circuit, for example, counter 7 counts days in a week, and the output is supplied to memory circuit 5 and decoder 8, and tempos of melodies different for days are indicated by the output of decoder 8. Then, by the index output from time set unit 1, the output of oscillator 2 is given to variable frequency dividers 16 and 15 to generate frequency outputs for accompaniment and main melody. Then, the output of oscillator 2 is given to variable frequency divider 4 also, and output pulses for the tempo designated by decoder 8 are given to variable frequency divider 14, and gate circuits 17 and 18 are opened by the output of divider 14, and meoldy data is read out successively from memory circuit 5 by the output of counters 6 and 7, thereby playing the melody. As a result, a timer unit can be obtained which can play different melodies as alarm each time the day in a week is changed.
