Abstract
PURPOSE: To stabilize operation by preventing the failure of main parts with an auxiliary power source is operated to make auxiliary power supply for the normal operation of the other electronic circuits than load upon the change of power supply voltage.
CONSTITUTION: Normal battery voltage is used while lowered by the circuit of a block A and when a heavy load operates the auxiliary power generated by a block B is supplied to the movement of a timepiece. When it has become not possible to obtain a fixed potential for -VSS1 due to the sudden change of the voltage given between power supply voltage +VDD and -VSS2, the stop of the timepiece is prevented by the auxiliary power supply from the block B.
