Abstract

PURPOSE:To provide, which can accomplish the warning operation in melody sounds with the sue of a simple construction, by using the outputs of the respective frequency stages of different frequencies as quasi-tone signals to generate melody sound signals. CONSTITUTION:When the arrival of an alarm time is detected by a coincidence circuit 10, the disired gate of a tone frequency generating circuit 12 are opened in accordance with the read-out of the programmable ROM of a control circuit 11. As a result, preset frequency dividing signals are generated in a preset order from the circuit 12 which is supplied with the frequency dividing signals of different frequencies from the respective dividing stages of a frequency circuit 2 as quasi-tone signals so that the melody sound signals are fed to a sound generating circuit. As a result, it is possible to accomplish the warning operation of the correct time or alarm in the melody sounds with the use of such a simple construction as uses the frequency dividing output for the time.
