PURPOSE:To utilize timer operation in a timer constituting part as second alarm information operation, by inhibiting the motor rotation of the timer constituting part before alarm output in a clock constituting part is generated while releasing the inhibiting state after alarm output is generated. CONSTITUTION:Timer operating output 66a is supplied to an AND gate 90 while the output of the AND gate 90 is connected to the gate inputs of N-MOS transistors 92, 94 for controlling the power source supplies of driving inverters 56a, 56b to make it possible to control the rotary driving of a step motor 60 for a timer. Because a timer sound generating output 66b is supplied to an AND gate 68 from a timer contact 66 and a reference signal phib for generating a timer sound from a frequency divider circuit 52 is supplied to the other input terminal of the AND gate 68, when the timer sound generating output 66b comes to H, the reference signal phib is supplied to a time information circuit 70 and a timer sound is generated by a speaker 72. |
