<P>PROBLEM TO BE SOLVED: To provide an electronic timepiece, in which the operation of a power generating means 11 can be confirmed surely, regardless of the state of electricity storing means. <P>SOLUTION: This electronic timepiece has the power generating means 1 and the electricity storage means 4, which stores the electric energy generated from the generating means 1 and is driven by the electric power stored in the storage means 4. The timepiece is provided with a power generation detecting means 2, which detects the power generating state of the generating means 1 and a switching means 7, which cuts off the generating means 1 and storage means 4 from each other, at detecting of the power generating state of the generating means 1. The timepiece is constituted so that the output from the generating means 1 is not be limited by the output of the storing means 4, by controlling the turning off of the switching means 7 provided between the power generating means 1 and the storage means 4. <P>COPYRIGHT: (C)2004,JPO |
