Title:
ELECTRONIC TIMEPIECE
Document Type and Number:
Japanese Patent JP2005003493
Kind Code:
A
Abstract:

To provide an electronic timepiece that can prevent the elastic change of an input spring by signal input operation and can appropriately maintain signal input timing.

A reset-to-zero press spring section 360a is pressed, or the like by a reset button 10 when resetting chronograph hands 4, 5 to zero in the timepiece having chronographs, and a signal input spring 360c is not pressed directly. Therefore, the urging force of the signal input spring 360c itself realizes contact to a reset terminal 701, so that the signal input spring 360c cannot be plastically deformed by the operation of the reset button 10. Then, since the plastic deformation of the signal input spring 360c can be prevented, timing can be maintained appropriately without causing the input timing of reset signals to deviate.
