Abstract
PURPOSE: To obtain an electronic watch where battery exchange is needless, by using a generator utilizing a piezo-electric morph and a secondary battery.
CONSTITUTION: A piezo-electric morph is utilized as generator 19 of electronic watch 18. For example, when a user carries a wrist watch with him, the piezo- electric morph in generator 19 can be bent because the part of chain 20 receives a bending displacement which changes always, and the piezo-electric morph can be made into an AC generator. Otherwise, the piezo-electric morph in the generator can be arranged in not only the chain but also the reverse side of the watch main body so that piezo-electric morph may receive the bending movement.
