Problems solved by technology
[0003] The oscillating structure of this timepiece is a oscillating structure with a complicated mechanism realized by parts such as a setting lever and a shift fork, because the clutch wheel moves in the axial direction of the winding stem, and there is also a The problem is that the outer diameter of the movement becomes large because of the travel that the clutch wheel needs to slide through and the ring parts such as the shift fork
However, in the state where the engagement between the setting wheel and the pointer train is completely released, it becomes a state in which the whole of the setting wheel hits the gear of the pointer setting train while performing the swing. , and the setting wheel cannot mesh with the pointer setting wheel train, so the pointer setting cannot be realized

Embodiment Construction
[0014] In a timepiece that is moved by a power source such as a motor and a barrel via a plurality of trains, there is a time display wheel that displays the time by connected hands, and a train of wheels by which the time display wheel meshes with a minute wheel, A timepiece in an embodiment of the present invention is explained with reference to the drawings. FIG. 1 is a cross-sectional view at the time of normal hand movement, and FIG. 2 is a cross-sectional view at the time of time correction. The timepiece 100 in the embodiment of the present invention has the winding stem 1 connected to the main plate 2 so as to be positioned in at least two axial positions of the normal hand movement time position and the time correction time position; Angled part 1c of stem 1 engages clutch wheel 4 with angular hole 4b on the inner circumference; setting wheel 5 movable vertically when winding stem 1 is placed in the normal hand movement moment position The setting wheel is kept in th...

The invention provides a timepiece in which, when a rocking has been performed, a setting wheel does not run onto a gear wheel of a hand setting train wheel. A setting wheel meshes with a clutch whee at a time correction time, and a mesh with the clutch wheel is released at a time hand motion time while being placed upward than the time correction time. At the time correction time, in a minute wheel, a power mesh part receiving a power from the setting wheel meshes with the setting wheel. Further, at the time hand motion time, in the minute wheel, a mesh release prevention part having been provided in an upper part of the power mesh part prevents the mesh with the setting wheel from being released.
Description
technical field [0001] The invention relates to a timepiece with hand setting for time correction. Background technique [0002] Among the oscillating structures of timepieces having a winding arbor, a clutch wheel and a setting wheel, an oscillating structure of a timepiece in which the winding arbor is pulled out through the setting lever and fork to engage the wheel has been known since ancient times. Movement in the axial direction of the winding stem engages the hand setting train and the clutch wheel. [0003] The oscillating structure of this timepiece is a oscillating structure with a complicated mechanism realized by parts such as the setting lever and the shift fork, because the clutch wheel moves in the axial direction of the winding stem, and there is also The problem is that the outer diameter of the movement becomes large because of the stroke that is required to slide the clutch wheel through and an annular part such as a shift fork. [0004] A swing structu...
