摘要:
There is realized a multifunction timepiece constituted to be able to constitute a plurality of types of hand operating train wheels by only changing positions of integrating parts without changing dimensions and shapes of parts of a movement.A movement of a multifunction timepiece includes a first train wheel rotation center, and a second train wheel rotation center. A train wheel for indicating calendar information is arranged to be rotatable relative to one of the first train wheel rotation center, and the second train wheel rotation center. When the first train wheel rotation center is arranged with a train wheel for indicating calendar information, the calendar information can be indicated by a small hand rotated to move by the train wheel, when the second train wheel rotation center is arranged with a fan shape hand operating train wheel for indicating the calendar information, the calendar information can be indicated by a small hand moved in a fan shape operating train wheel.

To realize a small-sized analog multifunction timepiece by adopting a fan shape moving hand mechanism which does not use a hairspring. A multifunction timepiece of the invention is provided with a day display mechanism for operating a small hand moving in a fan shape. The day display mechanism is provided with a day indicator driving wheel, a day jumper, a small day wheel for displaying calendar information, a hammer constituted to rotate based on rotation of a day indicator transmission wheel, and a day return spring for exerting a rotational force to the small day wheel. By bringing a cam contact portion of the hammer to a transmission cam outer periphery portion and exerting an elastic force to a return cam outer shape portion by a return spring portion of the day return spring, the small day wheel is constituted to be exerted with a rotational force in a constant direction.

To realize an analog multifunction timepiece capable of realizing plural movement layouts including a fan shape moving hand train wheel by only changing positions of integrating parts without changing dimensions and shapes of the parts of movements. A movement of a multifunction timepiece is provided with a first train wheel rotational center, a second train wheel rotational center, a third train wheel rotational center and a fourth train wheel rotational center. Calendar information can be displayed by a small hand moving to rotate centering on the first train wheel rotational center and the second train wheel rotational center. Calendar information can be displayed by a small hand moving in a fan shape centering on the third train wheel rotational center and the fourth train wheel rotational center.
摘要:
To realize a multifunctional watch which is constituted so as to be capable of forming a plurality of movement layouts without changing sizes and shapes of components for the movement only by changing positions where the components are incorporated. A movement 201 of a multifunctional watch is provided with a first train wheel rotational center and a second train wheel rotational center. The first train wheel rotational center and the second train wheel rotational center are aligned on a position between a main plate center 202c of a main plate 202 and a main plate outline portion of the main plate 202. On the first train wheel rotational center and the second train wheel rotational center, a train wheel guide portion for rotatably guiding a train wheel member is disposed, respectively. A train wheel for displaying time information or calendar information is aligned rotatably for on of the first train wheel rotational center and the second train wheel rotational center.

A multifunctional watch has a movement including first and second train wheel rotational centers each arranged at a position between a center of a main plate and an outline portion of the main plate. The first and second train wheel rotational centers are provided with respective first and second train wheel guide portions rotatably guiding respective first and second train wheel members about the respective first and second train wheel rotational centers. A first train wheel having the first train wheel member is arranged rotatably relative to the first train wheel rotational center for rotating one of the small hands only in a single direction of rotation to display the first calendar information. A second train wheel having the second train wheel member is arranged rotatably relative to the second train wheel rotational center for rotating another of the small hands only in a single direction of rotation to display the second calendar information.
