发明名称 POWER SUPPLY APPARATUS IN ELECTRICAL APPLIANCES
摘要 <p>A power supply apparatus for supplying power to an electronic wrist watch (3) includes a power generation portion (1) and a power storage portion (4) composed of a plurality of cells (41, 42) having the same capacitance. Switches (51, 52) are connected in series with the cells (41, 42), respectively, and a switch (53) is connected in series between the cells (41 and 42). Because these switches (51, 52, 53) are actuated by a signal from a voltage detection circuit (6), the time for the initial start can be reduced, and the continuous operation time can be extended.</p>
