Abstract
PURPOSE: To make stable the circuit operation, by releasing the low voltage under time correction, in the two pointer type electronic watch using constant low voltage circuit for minute power reduction.
CONSTITUTION: When the external switch S is OFF, the voltage lower than the cell voltage is fed to the oscillation circuit 1 and count circuit 3 from the constant low voltage circuit 2 except power supply ON, and the pointer signal ϕ01 10 and 20 seconds interval for normal pointer operation is outputted to the drive circuit 5 to drive the motor. When the switch S is ON, the output of the constant low voltage circuit is the same as the cell voltage, and the oscillation circuit 1 and the counter circuit 3 are operated at the cell voltage, and from the time correction circuit 4, the signal ϕ03 to operate forward fast feed of motor and reversing is fed to the drive circuit 5.
