Below, it demonstrates using a XY rectangular coordinate system as needed.

(Hand movement mechanism)
As shown in FIG. 4, the hand operating mechanism 40 mainly includes a 24-hour wheel 41, a heart cam 42, a transmission lever 43, a hand-operating lever 45, and a 24-hour display wheel 47.
As shown in FIG. 3, the 24-hour wheel 41 is rotatable around the central axis of the 24-hour wheel 41 by the main plate 12 through a shaft member 41 a provided on the −X side of the central axis O of the timepiece 1. It is supported.
The 24-hour wheel 41 is engaged with, for example, an intermediate wheel 19 provided integrally with the hour wheel 18. The intermediate wheel 19 transmits the driving force of the hour wheel 18 to the 24-hour wheel 41 while reducing the rotational speed of the hour wheel 18 by a factor of 1/2. As a result, the 24-hour wheel 41 rotates at a rotational speed that is 1/2 times that of the hour wheel 18, that is, at a rotational speed of one rotation per 24 hours.

  As shown in FIG. 4, the heart cam 42 is formed in a heart shape when viewed from the axial direction by two cam surfaces having convex curved surfaces. The heart cam 42 is attached to a shaft member 41a to which a 24-hour wheel 41 is attached. Of the boundary portions of the two cam surfaces of the heart cam 42, one boundary portion is the innermost portion 42a having the smallest separation distance from the central axis of the shaft member 41a (that is, the central axis of the 24-hour wheel 41), The other boundary portion is the outermost part 42b having the largest separation distance from the central axis of the shaft member 41a.

The transmission lever 43 is a long plate-like member and is provided so as to extend from the lever shaft member 44 toward the heart cam 42 side.
The base end portion of the transmission lever 43 is outside the radial direction of the 24-hour wheel 41 and is, for example, fitted and fixed to a lever shaft member 44 provided in the (−X, −Y) region. The shaft member 44 is pivotally supported so as to be rotatable.
The distal end portion of the transmission lever 43 is disposed in the (−X, + Y) region. The distal end portion of the transmission lever 43 is bent toward the heart cam 42 and serves as a slidable contact portion 43 a that slidably contacts the cam surface of the heart cam 42.

The needle-operating lever 45 includes a base portion 45a having a circular shape in plan view, a spring portion 45b that extends outward in the radial direction of the base portion 45a, and is curved in a U shape, and a spring portion sandwiching the base portion 45a. And a rotating tooth portion 45c provided on the opposite side to 45b.
The base portion 45 a of the needle-operating lever 45 is, for example, fitted and fixed to the lever shaft member 44, and is pivotally supported so as to be interlocked with the transmission lever 43 around the lever shaft member 44.

The spring portion 45 b of the hand movement lever 45 urges the hand movement lever 45 and the transmission lever 43 in the counterclockwise direction around the lever shaft member 44. As a result, the sliding contact portion 43a of the transmission lever 43 approaches and separates from the shaft member 41a of the 24-hour wheel 41 with the rotation of the 24-hour wheel 41 and the heart cam 42, while always in sliding contact with the cam surface of the heart cam 42. . Then, the transmission lever 43 and the needle movement lever 45 rotate around the lever shaft member 44.
The rotating tooth portion 45c of the hand lever 45 is formed in a fan shape that spreads at a predetermined center angle in plan view, and meshes with the 24-hour indicator wheel 47.
The 24-hour indicator wheel 47 is, for example, externally fitted and fixed to the instruction portion shaft member 81, and is pivotally supported so as to be interlocked with the instruction portion 6.

The hand movement mechanism 40 configured as described above operates as follows.
As shown in FIG. 4, the instruction unit 6 is located at one end 22 of the retrograde display area 21 when the instruction unit 6 starts to move. At this time, the sliding contact portion 43a of the transmission lever 43 is in contact with the outermost portion 42b of the heart cam 42 and is disposed at a position farthest from the central axis of the shaft member 41a.

Subsequently, as time passes, when the hour wheel 18 and the intermediate wheel 19 rotate in the clockwise direction, the 24-hour wheel 41 and the heart cam 42 that mesh with the intermediate wheel 19 rotate in the counterclockwise direction. At this time, the sliding contact portion 43 a of the transmission lever 43 moves so as to approach the shaft member 41 a of the 24-hour wheel 41 as the heart cam 42 rotates while slidingly contacting the cam surface of the heart cam 42. As a result, the transmission lever 43 and the hand movement lever 45 rotate counterclockwise about the lever shaft member 44.
The 24-hour indicator wheel 47 that meshes with the rotating tooth portion 45 c of the hand-operating lever 45 and the indicator portion 6 that is linked to the 24-hour indicator wheel 47 rotate clockwise about the indicator shaft member 81. Accordingly, the instruction unit 6 moves from one end 22 of the retrograde display area 21 toward the other end 23.

  As shown in FIG. 5, when 12 hours have elapsed from the start of movement of the instruction unit 6, the heart cam 42 rotates 180 °. At this time, the sliding contact portion 43a of the transmission lever 43 contacts the innermost portion 42a of the heart cam 42 and is disposed at a position closest to the central axis of the shaft member 41a. The instruction unit 6 is located at the other end 23 of the retrograde display area 21.

Next, as shown in FIG. 6, when the heart cam 42 further rotates counterclockwise with the passage of time, the sliding contact portion 43 a of the transmission lever 43 is in sliding contact with the cam surface of the heart cam 42. With the rotation of 42, it moves away from the shaft member 41 a of the 24-hour wheel 41.
Thereby, the transmission lever 43 and the hand movement lever 45 are rotated clockwise around the lever shaft member 44. Further, the 24-hour indicator wheel 47 meshing with the rotating tooth portion 45 c of the hand lever 45 and the indicating portion 6 interlocking with the 24-hour indicator wheel 47 rotate counterclockwise about the indicating portion shaft member 81. Accordingly, the instruction unit 6 moves from the other end 23 of the retrograde display area 21 toward the one end 22.

As shown in FIG. 7, when 12 hours have passed since the instruction unit 6 started moving from the other end 23 of the retrograde display area 21 toward the one end 22 (that is, 24 hours from the start of the movement of the instruction unit 6), the heart cam 42 is further rotated 180 °. At this time, the sliding contact portion 43a of the transmission lever 43 is in contact with the outermost portion 42b of the heart cam 42 and is disposed at a position farthest from the central axis of the shaft member 41a. The instruction unit 6 is located at one end 22 of the retrograde display area 21.
This completes the movement of the instruction unit 6 with a period of 24 hours.
