Abstract
PURPOSE: To eliminate the sense of unease for the user by securing generation of the alarm tone without any inhibiting section when the signal from the alarm setting circuit is supplied again after the alarm tone is stopped in the fixed time since generation of the alarm tone.
CONSTITUTION: At the time set at alarm setting circuit 60 of the mechanical system, output 64 changes from L to H to be applied to flip-flops 66 and 68. And timer circuit 58 is reset by single pulse 80 via AND gate 76, and then fixed cycle signal 82 is applied to flip-flops 68 and 84. The signal which turns to L with the fall of signal 82 is obtained at output 87 of flip-flop 84. Then modulated frequency 91 of divider circuit 46 is applied to alarm tone generator 62 for a fixed period to produce the alarm tone.
