Problems solved by technology

[0005] However, in the above-mentioned type, the mandrel parts are required between the winding stem and the correction lever and the reset lever, and the correction lever and the reset lever need to be arranged separately from each other, which increases the number of parts and the complexity of the structure
[0006] Also, in the latter type, since the correction and return action is performed by the restoring force of the spring, the correction and return action becomes unstable

Embodiment Construction

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0018] figure 2 An example of an electronic timepiece with a correction mechanism according to the present invention is shown.

[0019] The electronic watch is provided with a battery 2 used as a power source, a quartz crystal 3 powered by the battery 2 to oscillate, a circuit for frequency division and output of the signal of the quartz crystal 3, i.e. IC4, and a pulse signal conversion from IC4 A converter 5 for mechanical rotational force, a gear train 6 for transmitting rotational force to the hands of the watch through the converter 5, and a correction mechanism 7 for stopping the hands of the watch when the watch is adjusted or the like.

[0020] Here, when the user operates and pulls up the winding stem 8 to adjust the watch, etc., the correcting mechanism 7 has the function of correcting the gear that moves the watch hands, such as the 5th gear 9...

Abstract

A correcting lever is integrally provided with a correcting portion for correcting a fifth wheel, a reset portion brought into contact with a reset pin for stopping an output of a pulse signal from an IC, a return spring portion and an engaged portion and is rotatably supported about a rotary center portion (hole) to a base plate. An engagement portion of a winding stem is engaged with the engaged portion by operation of drawing the winding stem and the correcting lever is shifted against the biasing force by a return spring portion in accordance with the motion of the winding stem so that the correcting portion and the reset portion are forcibly rotated to the fifth wheel and the reset pin, respectively, about the rotary center portion (hole) to thereby perform the correcting and reset actions.

Description

technical field [0001] The present invention relates to an electronic watch having a correcting mechanism for correcting a gear that advances the hands of the watch so that the hands are stopped by pulling out the winding stem when the watch is adjusted etc. Stops the output of a pulse signal from the circuit. Background technique [0002] For example, the following types are known as electronic watches having a correction mechanism. [0003] One type is that a winding stem is operated to be pulled out to operate a correcting lever and a reset lever by the movement of a part which engages with the winding stem and is called a "mandarin duck", thereby performing correction and Reset action. [0004] Another type is: operating a winding stem to pull it out so that the engagement between the winding stem and a spring is released to release the spring force and perform the correction and Reset action. [0005] However, in the above-mentioned type, the mandrel parts are requi...
