PURPOSE:To prevent an error from occurring when a load with large power consumption is driven without increasing size, by disconnecting a power source and a feeding capacitor in response to a load operation signal and powering on the load with large power consumption through a delay circuit. CONSTITUTION:When the load operation signal is generated by an alarm switch 7 at alarm time, a transistor (TR)16 turns off and a light-load timer circuit body A is powered on by the capacitor 17 disconnected from the power source. At the same time, a gate 9 is opened through the delay circuit B responding to the load operation signal to control a TR10 according to a frequency division output f1; and a speaker 11 with large power consumption is fed from the power source and even when the power voltage drops owing to the large power consumption, the main body A operates normally. Thus, the electronic timepiece circuit which causes no error even when the load with large power consumption is driven is obtained without increasing its size. |
