Description of the Prior Art [0002] Conventionally, there is known a mechanical timepiece equipped with a display mechanism called a retrograde mechanism in which a day of the week or the like is displayed by a sector-shaped graduation of a circle and in which a pointer of the indicator (indicating element) indicating this sector moves from one side to the other side around the central axis of the circle sector before instantly returning to the first side this operation being carried out repeatedly (see, for example, JP-A-2006-226990 (first patent document)).
    In the following, a case will be described by way of example in which a day of the week is displayed by such a display mechanism.
    The days of the week, Monday, Tuesday, Wednesday, ..., Sunday are sequentially displayed from one end (the other side) to the terminal end (the first side) of the display area. shaped like a circle sector, and the indicator hand indicates the current day of the week with the passage of time (that is, it indicates one of the days between Monday and Sunday). When it's back on Monday, the indicator hand is brought back instantaneously from Sunday to Monday displayed in the display area.
    The display mechanism disclosed in the first patent document is equipped with an intermediate day indicator driven by an hour wheel, a cam configured to be rotated by this intermediate day indicator, a rotary lever pushed by a spring when in contact with the cam, and a small day indicator that moves together with a wheel portion provided on the lever and to which a day hand can be mounted. In the invention disclosed in the first patent document, as the lever rotates away from the center of rotation of the cam, the spring pressure force for the lever is accumulated, and this accumulated pressure force is released at the moment of cessation of the cam cycle, which allows a return of the day hand to the initial position (reset).

    In the plan view of the dial 2 of the timepiece 1, the direction 12 o'clock - 6 o'clock is defined as the direction X, the side of the 12 o'clock being defined as the + X side, and the side of the 6 hours as the side -X. In the plan view of dial 2 of timepiece 1, the 3 o'clock - 9 o'clock direction is defined as the Y direction, the 3 o'clock side being defined as the + Y side, and the 9 o'clock side as the -Y side. In the following description, the orthogonal coordinate system X-Y will be used as appropriate. Needle Movement Mechanism [0058] As shown in FIG. 4, the needle movement mechanism 40 is composed mainly of a 24-hour wheel 41, a heart-shaped cam 42, a transmission lever 43, a lever for moving the needle 45, and a wheel 24 hour display 47.
    As shown in FIG. 3, the 24-hour wheel 41 is supported by the plate 12 to be rotatable about the central axis of the 24-hour wheel 41 by a rod 41 arranged on the side -X of the central axis O of the piece watchmaking 1.
    The 24-hour wheel 41 meshes, for example, with an intermediate wheel 19 integral with the hour wheel 18. The intermediate wheel 19 transmits the drive of the hour wheel 18 to the wheel 24 hours 41 while halving the speed of rotation. As a result, the 24-hour wheel 41 rotates half as fast as the hour wheel 18, i.e. at a speed of one revolution in 24 hours.
    As shown in FIG. 4, due to two convex cam surfaces, the heart-shaped cam 42 is formed with a heart-shaped configuration as seen from the axial direction. The heart-shaped cam 42 is mounted on the rod 41a on which the 24-hour wheel 41 is mounted. Of the two end cam end portions of the heart-shaped cam 42, an end portion is the innermost portion 42a at a minimum separation distance from the central axis of the stem 41a (this is that is, the central axis of the 24-hour wheel 41), and the other end portion is the outermost portion 42b at a maximum separation distance from the central axis of the rod 41a.
    The transmission lever 43 is an elongate plate-shaped member, which is provided to extend from the lever rod 44 towards the side where there is the heart-shaped cam 42.
    The proximal end of the transmission lever 43 is radially on the other side of the 24-hour wheel 41; it is mounted on the lever rod 44 provided in the area (-X, -Y), and is supported so as to be rotatable about the lever rod 44.
    The distal end of the transmission lever 43 is arranged in the area (-X, + Y). The distal end of the transmission lever 43 is bent toward the side of the heart-shaped cam 42, and constitutes a sliding contact portion 43a which is slidably contacted with the cam surface of the heart-shaped cam. 42.
    The lever for moving the needle 45 comprises a base portion 45a which is circular in the plan view, a spring portion 45b which extends outwardly in the radial direction of the base portion 45a and is then bent with a U shape, and a rotatable toothed portion 45c provided opposite the spring portion 45b with the base portion 45a therebetween.
    The base portion 45a of the needle movement lever 45 is mounted on the lever rod 44, and is pivotally supported to rotate in combination with the transmission lever 43 about the lever rod. 44.
    The spring portion 45b of the lever for moving the needle 45 pushes the lever for moving the needle 45 and the transmission lever 43 in the opposite direction of the needles around the lever rod 44 As a result, the sliding contact portion 43a of the transmission lever 43 moves toward and against the shaft 41a of the 24 hour wheel 41 with the rotation of the 24 hour wheel 41 and the heart shaped cam 42 although still being in sliding contact with the cam surface of the heart-shaped cam 42. Also, the transmission lever 43 and the needle-moving lever 45 rotate around the lever rod 44.
    The rotatable toothed portion 45c of the needle displacement lever 45 has a circle sector shape extending at a predetermined center angle in the plan view, and meshes with the 24-hour display wheel. 47.
    The 24-hour display wheel 47 is attached to the rod of the indicating member 81, for example, by being inserted therein, and is supported so as to be rotatable to rotate together with the indication element 6.
    The needle movement mechanism 40, constructed as described above, operates in the following manner.
    As shown in FIG. 4, at the beginning of the movement of the indicating element 6, the indicating element 6 is located at a first end 22 of the display zone 21. At this moment, the sliding contact portion 43a of the transmission 43 is in contact with the outermost portion 42b of the heart-shaped cam 42, and is at the furthest position from the central axis of the shaft 41a.
    Then, when, with the passage of time, the hour wheel 18 and the intermediate wheel 19 turn in the clockwise direction, the 24-hour wheel 41 meshing with the intermediate wheel 19 and the cam heart shape 42 turn counterclockwise. At this moment, the sliding contact portion 43a of the transmission lever 43 moves towards the rod 41a of the 24-hour wheel 41 with the rotation of the heart-shaped cam 42 while being in contact with the surface As a result, the transmission lever 43 and the lever for moving the needle 45 rotate counterclockwise about the lever rod 44.
    In addition, the 24-hour display wheel 47 meshes with the rotatable toothed portion 45c of the lever for moving the needle 45 and the indicating element 6 moving in conjunction with the display wheel 24. hours 47 turn clockwise around the rod of the indicating member 81. Accordingly, the indicating member 6 moves from the first end 22 towards the other end 23 of the display area 21.
    As shown in FIG. 5, when 12 hours have elapsed since the beginning of the movement of the indicating element 6, the heart-shaped cam 42 has rotated 180 degrees. At this time, the sliding contact portion 43a of the transmission lever 43 is in contact with the innermost portion 42a of the heart-shaped cam 42, and is at a position closest to the axis central of the rod 41a. Also, the indicating element 6 is located at the other end 23 of the display zone 21.
    Then, when, as shown in FIG. 6, the heart-shaped cam 42 continues to rotate counter-clockwise with the passage of time, the sliding contact portion 43a moves from the shaft 41a of the 24-hour wheel 41 with the rotation. the heart-shaped cam 42 while in sliding contact with the cam surface of the heart-shaped cam 42.
    As a result, the transmission lever 43 and the lever of movement of the needle 45 rotate clockwise around the lever rod 44. In addition, the display wheel 24 hours 47 meshing with the rotating toothed portion 45c of the needle movement lever 45 and the indicating member 6 moving in conjunction with the 24-hour display wheel 47 rotate counterclockwise around of the rod of the indicating element 81. Accordingly, the indicating element 6 moves from the other end 23 towards the first end 22 of the display zone 21.
    As shown in FIG. 7, when 12 hours have elapsed since the beginning of the movement of the indicating element 6 from the other end 23 towards the first end 22 of the display area 21 (i.e., 24 hours after the beginning of the movement of the indicating element 6), the heart-shaped cam 42 rotated 180 degrees more. At this time, the sliding contact portion 43a of the transmission lever 43 is in contact with the outermost portion 42b of the heart-shaped cam 42, and is at the furthest position from the axis. central of the rod 41a. Also, the indication element 6 is located at the first end 22 of the display area 21.
    In this way, the needle movement of the indication element 6 to the 24-hour cycle is complete.
    Sense Display Element [0079] As shown in FIGS. 4 to 7, the sense display member 30 serves to show the direction of movement when the indicating member 6 is moving from the first end 22 to the other end 23 of the display area 21, or from the other end 23 to the first end 22 of the display area 21; for example, there is provided on the surface of a disc 68 a direction display wheel 66 constituting the switching mechanism 50 described below. The direction display wheel 66 will be described in detail below.
    Apart from the zone corresponding to the opening 15, the direction display element 30 is covered by the dial 2. The direction display element 30 is equipped with a plurality (three in the present embodiment) of first markings 31 indicating the first end direction 22 to another end 23 of the display area 21 and a plurality (three in the present embodiment) of second markings 32 indicating the direction other end 23 to first end 22 of the display area 21.
    The first markings 31 and the second markings 32 are provided at regular intervals (at an inclination angle of 60 degrees in the present embodiment) and alternatively in the peripheral direction of the display element. 30.
