Patent ID: 8907507

Claim:
A power generator device comprising: a case; an operating member that is operated upon power generation; a power generator part that generates an induced electromotive force when a driven part is driven; an elastic part that is connected to the driven part and is configured to accumulate an elastic force upon being applied an external force and output the accumulated elastic force to drive the driven part; and a connection disengagement mechanism that is configured to be engageable with the operating member and the elastic part; wherein the connection disengagement mechanism interconnects the operating member and the elastic part and transmits an operating force of the operating member to the elastic part while the operating member is positioned between a pre-operation position and an accumulation complete position at which a predetermined elastic force is accumulated at the elastic part; and the connection disengagement mechanism disengages the interconnection between the operating member and the elastic part and allows the elastic part to output the accumulated elastic force when the operating member moves past the accumulation complete position.
