  Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. However, in each figure, the size and scale of each part are appropriately different from the actual ones. Further, since the embodiments described below are preferable specific examples of the present invention, various technically preferable limitations are attached thereto. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these forms.

<First Embodiment>
First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram showing a schematic configuration of a timepiece 100 according to the first embodiment of the present invention. Although not shown in FIG. 1, the timepiece 100 includes an exterior case, a cover glass, and a back cover. The cover glass is attached to the exterior case so as to cover the disk-shaped dial plate 20. The dial plate 20 is arranged as a time display portion.

  The dial 20 is provided with hands 21, 22, and 23. Further, the dial 20 has a rectangular first small window 70 and a pointer 71 in the 5 o'clock direction from the center, and a circular second small window 80 and a pointer 81 in the 11 o'clock direction are rectangular in the 3 o'clock direction. A small calendar window 24 is provided. The dial 20, the hands 21, 22, 23, the first small window 70, the second small window 80, the calendar small window 24, and the like are visible through the cover glass.

  On the side surface of the exterior case, a crown 50 is provided at a position in the 3 o'clock direction from the center of the dial plate 20. By operating the crown 50, the time is corrected, the calendar is corrected, and the day of the week is corrected.

  As shown in FIG. 1, a scale that divides the outer periphery into 12 parts and a scale that divides into 60 parts are written on the outermost periphery of the dial 20. Using this scale, the hand 21 displays “second”, the hand 22 displays “minute”, and the hand 23 displays “hour”.

  On the outer periphery of the circular first small window 70 provided on the dial 20, a scale that divides the outer periphery into 24 parts is written. Although illustration is omitted near the scale of the first small window 70, numbers such as “24”, “6”, “12”, “18”, etc. are also written. The pointer 71 displays “hour” of a 24-hour display using this scale.

  On the outer periphery of the circular second small window 80 provided on the dial plate 20, a display area for dividing the outer periphery into seven is provided. In these display areas, although not shown, characters representing days of the week such as “SU”, “MO”, “TU”, “WE”, “TH”, “FR”, “SA” are written. There is a case. In addition, the characters “day”, “month”, “Tue”, “Wed”, “Thurs”, “Fri”, and “Sat” may be written as Japanese. The pointer 71 points to any of these characters and displays the day of the week. In addition, about the character to be described, the form of a character, etc., it can change suitably.

  The calendar small window 24 is provided in an opening portion in which the dial 20 is opened in a rectangular shape, and numerals (not shown) are visible from the opening portion. This number represents the “day” of the date.

  Next, the movement of the timepiece 100 of this embodiment will be described. FIG. 2 is a plan view of the movement 2 in the present embodiment as viewed from the surface side. In the present embodiment, in the timepiece 100, the side on which the user visually recognizes the time by the scale of the dial 20 is the front side, and the side attached to the wrist or arm is the back side. The movement 2 includes a train wheel that transmits the driving force to the pointer. The train wheel includes an hour wheel 4 that is attached with an hour hand and rotates once in 12 hours. Furthermore, the movement 2 includes a date wheel 10 that is a calendar wheel disposed on the surface side of the main plate 3 and a drive mechanism that drives the date wheel 10. The movement 2 in this example is a mechanical type, but may include a ground plane 3 and a battery and a stepping motor disposed on the back side of the ground plane 3 in the same manner as a general movement for analog quartz. In this case, the movement 2 includes a circuit board in which a crystal resonator serving as a reference signal source and an IC serving as a control circuit are incorporated, and a train wheel that transmits the driving force of the stepping motor to a pointer.

  The date dial 10 is a general date dial including a ring-shaped date plate 11 and an internal gear 12 integrally formed on the inner periphery of the date plate 11. For this reason, the internal gear 12 is formed with 31 teeth on the inner periphery of the date plate 11. On the surface of the date plate 11, date information as calendar information, specifically, numbers from “1” to “31” representing the date are displayed. The numbers displayed on the surface of the date plate 11 are visible from the calendar small window 24 described above.

  FIG. 8 is a cross-sectional view taken along the line I-I ′ in FIG. 2. 9 is a cross-sectional view taken along line II-II ′ in FIG. As shown in FIGS. 8 and 9, the date dial 10 is disposed on the main plate 3. The drive mechanism for driving the date dial 10 includes a date indicator driving wheel 15 that rotates once in 24 hours in conjunction with the hour wheel 4. As shown in FIG. 8, the date driving wheel 15 is rotatably supported by the main plate 3. The date indicator driving wheel 15 is an example of a first vehicle guided by the main plate 3, and is pivotally supported by a hole formed in the main plate 3. FIG. 3 is a plan view of the date driving wheel 15 in the present embodiment. As shown in FIG. 3, the date indicator driving wheel 15 includes a date feeding claw 151. The date feeding claw 151 feeds the internal gear 12 by one tooth per day to rotate the date dial 10 by one day. The date indicator driving wheel 15 includes two day feeding claws 152. As will be described later, the day star wheel 40 has 14 teeth, and the day feeding claw 152 rotates the day star wheel 40 by two teeth each time the date indicator driving wheel 15 makes one rotation. In this embodiment, two day feeding claws 152 are provided and the day star wheel 40 is rotated by two teeth. However, the day star wheel 40 is fed by two teeth by using the day feeding claws 152 as one. It does not matter. When the number of teeth formed on the day star wheel 40 is seven, the day star wheel 40 may be fed by one tooth with the day feeding claw 152 as one.

  As shown in FIG. 2, the internal gear 12 of the date dial 10 is engaged with the tip 161 of the date jumper 16 attached to the main plate 3, and the movement (rotation) of the internal gear 12 is restricted. FIG. 4 is a plan view of the date jumper 16 in the present embodiment. As shown in FIG. 4, the date jumper 16 is a plate-like member disposed on the inner peripheral side of the date dial 10. 10 is a cross-sectional view taken along line III-III ′ in FIG. 2. As shown in FIG. 10, the date jumper 16 is attached to the main plate 3 with the screw 17 through the date dial holder 30.

  The date jumper 16 is always urged in the direction in which the tip 161 is directed toward the internal gear 12 by its own spring force. The front end portion 161 includes two inclined surfaces 162 and 163 that intersect at the front end. Therefore, when the date indicator driving wheel 15 rotates the date dial 10 counterclockwise in FIG. 2, the teeth of the internal gear 12 abut against the inclined surface 162 on the front side in the rotational direction of the tip portion 161, and the internal gear 12 Rotates while pushing the date jumper 16 against its urging force. When the tooth of the internal gear 12 exceeds the tip 161 of the date jumper 16, the tooth contacts the other inclined surface 163 and rotates. The date jumper 16 is engaged with the internal gear 12 in a state where the tip 161 of the date jumper 16 is positioned between the two teeth and each tooth is in contact with the inclined surfaces 162, 163, and the date indicator. The rotation of 10 also stops. When the date indicator 10 stops rotating, the date jumper 16 is maintained in a state in which the date jumper 16 is engaged with the internal gear 12 by its urging force, so that the rotation direction of the date indicator 10 is restricted. Accordingly, the date indicator 10 is intermittently driven by the date indicator driving wheel 15 and the date jumper 16 to restrict the rotation direction.

  Positioning of the date dial 10 in the axial direction is performed by the date dial presser 30. FIG. 5 is a plan view of the date dial holder 30. As shown in FIG. 5, the date dial holder 30 is a plate-like member disposed on the inner peripheral side of the date dial 10. As shown in FIGS. 8 to 10, the date dial holder 30 is disposed on the date jumper 16, and is attached to the main plate 3 with the screw 17 together with the date jumper 16 as shown in FIG. 10. The date dial holder 30 includes a guide portion 31 disposed on the surface side of the internal gear 12 of the date dial 10 (the timepiece surface side in FIG. 2). For this reason, the date dial 10 does not come off to the surface side of the movement 2 even in the state of the movement 2 before being incorporated into the exterior case. Therefore, the movement 2 can be shipped and transported with the date dial 10 attached. The date dial holder 30 is formed with an exposed portion 32 that exposes the front end portion 161 of the date jumper 16 that engages with the internal gear 12 to the surface side when the movement 2 is viewed from the surface side.

  The date indicator holder 30 is also formed with a day jumper 36 that engages with the day star wheel 40 described later. Similarly to the day jumper 16, the day jumper 36 also includes a tip 351 and inclined surfaces 352 and 353.

  As shown in FIG. 2, a day star wheel 40 is arranged coaxially with the hour wheel 4 on the inner peripheral side of the date dial 10. Fourteen teeth 41 are formed on the day star wheel 40. As shown in FIG. 8, the teeth 41 engage with two day feeding claws 152 formed on the date indicator driving wheel 15. When the date indicator driving wheel 15 is rotated once in 24 hours in conjunction with the hour wheel 4, the day star wheel 40 is engaged with the day feeding claw 152 and rotated by two teeth. For this reason, by displaying the day information of two kinds of character types, kanji and alphabet, on the dial of the second small window 80, the day information can be displayed with the character type selected by the user. Since the day star wheel 40 makes one rotation on the seventh day, 360/7 rotates about 51.4 degrees in one day.

  As shown in FIG. 2, the teeth 41 of the day star wheel 40 are urged by the tip 351 of the day jumper 36 formed on the date dial holder 30. The day jumper 36 is always urged in the direction in which the tip 351 is directed toward the teeth 41 by its own spring force. The tip 351 includes two inclined surfaces 352 and 353 that intersect at the tip. For this reason, in FIG. 2, when the day star wheel 40 is rotated clockwise by the date indicator driving wheel 15, the teeth 41 abut against the inclined surface 352 and push the day jumper 36 against the biasing force. Further, when the teeth 41 get over the tip 351, the teeth 41 abut against the inclined surface 353 and rotate. When the two teeth come into contact with the inclined surfaces 352 and 353 and the tip portion 351 is positioned between the teeth 41, the day star wheel 40 stops. When the day star wheel 40 stops rotating, the day jumper 36 is kept engaged with the teeth 41 by its urging force, so that the direction of rotation of the day star wheel 40 is restricted. Therefore, the day star wheel 40 is intermittently driven by the date indicator driving wheel 15 and the day jumper 36 to restrict the rotation direction.

  As shown in FIG. 2, the day star wheel 40 is provided with a day star pinion 42. The sun star kana 42 is a gear for feeding the day star intermediate wheel 43. In the present embodiment, as shown in FIGS. 2 and 9, a day star intermediate wheel 43 and a day hand wheel 44 are provided as a train wheel lined with the day star kana 42. Here, the day star wheel 40 is pivotally supported by the second wheel 5 guided by the main plate 3 via the hour wheel 4. That is, the day star wheel 40 functions as a first car guided by the main plate 3 through the parts of the second wheel 5 and the hour wheel 4 with the hour wheel 4 as the rotation axis.

  The day star intermediate wheel 43 and the day hand wheel 44 are rotatably attached to the date indicator holder 30 as shown in FIG. As shown in FIG. 5, the date dial holder 30 is provided with plane guide holes 33 and 34. The day star intermediate wheel 43 is pivotally supported by the plane guide hole 33, and the day hand wheel 44 is pivotally supported by the plane guide hole 34. Therefore, the day star intermediate wheel 43 and the day hand wheel 44 are also positioned in the plane direction by the date indicator holder 30. That is, the day hand wheel 44 is guided by the date indicator holder 30 and is incorporated on the opposite side of the main plate 3 with respect to the date indicator holder 30. The day hand wheel 44 functions as a second car that rotates in conjunction with the day star wheel 40 (an example of the first car) guided by the main plate 3.

  The day star intermediate wheel 43 is arranged to engage with the day star pinion 42, and the day hand wheel 44 is arranged to engage with the day star intermediate wheel 43. Here, the number of teeth of the day star kana 42 and the day hand wheel 44 is set to be the same. Therefore, when the day star wheel 40 rotates about 51.4 degrees, which is two teeth, the day hand wheel 44 also rotates about 51.4 degrees via the day star pinion 42 and the day star intermediate wheel 43. On the day hand wheel 44, a pointer 81 of the second small window 80 shown in FIG. Accordingly, when the day star wheel 40 is rotated about 51.4 degrees, which is two teeth, the day hand wheel 44 is also rotated about 51.4 degrees accordingly, and “SU” displayed on the dial of the second small window 80 is displayed. ”Or“ day ”is indicated by the pointer 81. Thus, in this embodiment, the day of the week is displayed by the hands 81. However, the present invention is not limited to such a configuration, and a day plate on which day information is displayed may be provided coaxially with the day star 40 and the day display may be performed by the day plate. As described above, in the present embodiment, the day hand wheel 44 functions as a display wheel for performing calendar display other than date display.

  As shown in FIGS. 2 and 8, the date indicator driving wheel 15 is provided with a 24-hour intermediate wheel 60 coaxially with the date indicator driving wheel 15. The phases of the date indicator driving wheel 15 and the 24-hour intermediate wheel 60 are held by a central angle dowel 61 provided on the date indicator driving wheel 15. In the present embodiment, as shown in FIGS. 2 and 8, a 24-hour wheel 62 is provided as a wheel train aligned with the 24-hour intermediate wheel 60. As shown in FIG. 8, the 24-hour wheel 62 is rotatably attached to the date dial holder 30. As shown in FIG. 5, the date dial holder 30 is provided with a plane guide hole 35. The 24-hour wheel 62 is pivotally supported by the plane guide hole 35. Therefore, the 24-hour wheel 62 is also positioned in the plane direction by the date dial holder 30. Further, the 24-hour wheel 62 is arranged to engage with the 24-hour intermediate wheel 60 as shown in FIG. In this embodiment, when the date indicator driving wheel 15 rotates once, the 24-hour wheel 62 is also rotated once. The 24-hour wheel 62 rotates once in 24 hours in conjunction with the date indicator driving wheel 15. The 24-hour wheel 62 is guided by the date indicator holder 30 provided with the planar guide hole 35 and is incorporated on the opposite side of the main plate 3 with respect to the date indicator holder 30. The 24-hour wheel 62 functions as a second car that rotates in conjunction with the date indicator driving wheel 15 (an example of the first car) guided by the main plate 3. The 24-hour wheel 62 pivotally supports the pointer 71 of the first small window 70 shown in FIG. 1, and the pointer 71 indicates a scale or time number displayed on the dial of the first small window 70. , Display at 24 o'clock. As described above, in the present embodiment, the 24-hour car 62 functions as a display car that performs time display. The time display in this case can be said to be a second time display different from the first time display by the hands 21, 22, and 23.

  Positioning in the axial direction of the day hand wheel 44 as a display wheel for displaying a calendar other than the date display and the 24-hour wheel 62 as a display wheel for displaying time is performed by a day hand wheel presser 55 as a display wheel presser. . FIG. 6 is a plan view of the day hand wheel presser 55 in the present embodiment. As shown in FIG. 6, the day hand wheel presser 55 is a plate-like member. As shown in FIGS. 8 to 10, the day hand wheel presser 55 is disposed so as to cover the day hand wheel 44 and the 24-hour wheel 62 from the surface side.

  As shown in FIGS. 8 to 10, the day hand wheel presser 55 is positioned in the axial direction by a day hand wheel presser seat 56 as a display wheel presser seat. FIG. 7 is a plan view of the day hand wheel presser seat 56 in the present embodiment. As shown in FIG. 7, the day hand wheel presser 55 is a plate-like member. As shown in FIGS. 8 to 10, the day hand wheel presser seat 56 is disposed on the date wheel holder 30. In the present embodiment, planar guide holes 33, 34, and 35 are formed in the date indicator holder 30, and the day star intermediate wheel 43, the day hand wheel 44, and the 24-hour wheel 62 are rotatably supported. A day hand wheel presser seat 56 is arranged on the date indicator presser 30, and the day hand intermediate wheel 43, day hand wheel 44, and 24 hour wheel are provided by the day hand wheel presser 55 sandwiching the day hand wheel presser seat 56. 62 is positioned in the axial direction.

  In this embodiment, a screw 90 and a screw pin 91 as a fixing member are used in order to fix the day hand wheel presser seat 56 and the day hand wheel presser 55 to the date wheel holder 30. FIG. 11 is a perspective view showing the positional relationship between the date indicator holder 30, the day hand indicator holding seat 56, and the screw pin 91. As shown in FIG. 11, three screw pins 91 are inserted into the date indicator holder 30 and the day hand indicator holding seat 56 from the back side of the date indicator holder 30. Then, as shown in FIGS. 8 and 10, the screw 90 is inserted from the surface side of the day hand wheel presser 55 and the screw 90 is tightened into the screw pin 91. The day hand wheel presser seat 56 and the day hand wheel holder 55 are fixed.

  As described above, in order to form the day jumper 36 having an urging force on the date indicator holder 30, the date indicator holder 30 needs to be a plate-like member having a certain degree of thinness. Therefore, just by inserting a general screw pin into the date dial holder 30, it is not possible to secure a fixing force (rotational torque) that exceeds the tightening force of the screw. Further, in order to secure the pulling force of the screw pin, it is conceivable to press-fit the screw pin into the date indicator holder 30. However, since the date indicator holder 30 is a thin plate as described above, The vehicle presser 30 will be deformed. Therefore, in the present embodiment, the screw pin 91 is formed of a cylindrical portion and a collar portion formed continuously with the cylindrical portion, and a part of the collar portion is parallel to the axial direction of the cylindrical portion. A plane portion is formed. The date wheel presser 30 is formed with a deformation hole that engages with the flange portion, and the day hand wheel presser seat 56 is formed with a press-fitting hole having a screw pin 91 tightening margin. In this embodiment, with such a configuration, it is possible to secure a fixing force (rotational torque) that is superior to a screw tightening force and a screw pin pulling force. Hereinafter, the details of the screw pin 91, the date indicator presser 30 in which the deformation hole is formed, and the day hand wheel presser seat 56 in which the press-fitting hole is formed in the present embodiment will be described.

  FIG. 12 is a plan view of the screw pin 91 in the present embodiment, and FIG. 13 is a side view of the screw pin 91. As shown in FIGS. 12 and 13, the screw pin 91 includes a cylindrical portion 92 and a flange portion 93, and a flat portion 94 parallel to the axial direction of the screw pin 91 is formed in a part of the flange portion 93. Is provided. The collar portion 93 includes a first collar portion 93a having the largest width W1 in the direction perpendicular to the plane portion 94, and a second collar portion 93b having a width W2 in the direction perpendicular to the plane portion 94 smaller than the width W1. . Therefore, a surface 93c is formed on the surface side of the first collar portion 93a. The diameter R1 of the outer periphery of the cylindrical portion 92 is formed to be smaller than the width W1.

  As shown in FIG. 5, the date dial holder 30 has three deformation holes 300 formed therein. FIG. 14 is an enlarged view of the deformation hole 300. As shown in FIG. 14, the deformation hole 300 is formed with a flat portion 301 in accordance with the flat portion 94 of the screw pin 91. The width W3 in the direction perpendicular to the plane portion 301 is formed to be slightly larger than the width W2 of the second collar portion 93b. When the screw pin 91 is inserted into the deformation hole 300 from the back surface side of the date dial holder 30, the surface 93c on the front side of the first collar portion 93a contacts the back surface of the date dial holder 30 as shown in FIGS. Touch. Then, the second collar portion 93 b engages with the deformation hole 300. A flat surface portion 94 is formed on the second collar portion 93 b, and the flat surface portion 94 engages with the flat surface portion 301 of the deformation hole 300. Therefore, the movement of the screw pin 91 in the rotational direction is restricted by the plane portion 94 and the plane portion 301. As a result, even when the screw pin 91 is inserted into the thin date dial holder 30, a fixing force (rotational torque) that is superior to the screw tightening force is ensured.

  As shown in FIG. 7, a press-fitting hole 500 is formed in the day hand wheel pressing seat 56 at a position corresponding to the deformation hole 300. FIG. 15 is an enlarged view of the press-fitting hole 500. In FIG. 15, the hole indicated by the solid line is the press-fitting hole 500, and the dotted line indicates the outer periphery of the cylindrical portion 92 in the screw pin 91. As shown in FIG. 15, a tightening margin A is provided in the press-fitting hole 500. Therefore, as shown in FIGS. 8 and 10, by fixing the cylindrical portion 92 of the screw pin 91 into the press-fitting hole 500, the fixing force (pull-out force) of the screw pin can be ensured. Since the day hand wheel pressing seat 56 does not require the elastic force like the date wheel pressing member 30, the axial thickness can be made relatively large. As a result, the rigidity of the day hand wheel pressing seat 56 can be made relatively high, and even if the screw pin 91 is press-fitted into the press-fitting hole 500 as described above, the day hand wheel pressing seat 56 is not deformed.

  In the present embodiment, a mechanism for performing day display and 24 o'clock display using a pointer is provided between the date indicator holder 30 and the day hand indicator holder 55. Further, in order to fix the day hand wheel pressing seat 56 and the day hand wheel pressing body 55 with respect to the date indicator holder 30, a screw pin 91 and a screw 90 are used. In the assembly process, the screw pin 91 is inserted from the back side of the date dial holder 30 and further press-fitted into the day wheel presser seat 56.

In this state, the fixing force (withdrawal force) by the press-fitting hole 500 of the day hand wheel presser seat 56 with respect to the screw pin 91 is such that the wheel presser 30, the day hand wheel presser seat 56, and the screw pin 91 are handled as an integral part. As much as possible.
That is, the fixing force (extraction force) by the press-fitting hole 500 is such that the screw pin 91 does not come off when the wheel presser 30, the day hand wheel presser seat 56, and the screw pin 91 are handled as an integral part. Force) and may be very small compared to the fixing force (rotational torque) against screw tightening. Since the fixing force by the press-fitting hole 500 can be reduced in this way, the distortion applied to the day hand wheel presser seat 56 is reduced, and the day hand wheel presser seat 56 can be structured to be difficult to deform.

As described above, the date jumper 16 is disposed on the back surface side of the date dial holder 30. As shown in FIG. 4, the date jumper 16 has a first collar portion 93 a at a position corresponding to the deformation hole 300. A screw pin clearance hole 165 having a diameter larger than the width W1 is formed.
In the assembling process, the date jumper 16 is arranged on the surface of the main plate 3, and the date indicator presser 30 and the day wheel presser seat 56 to which the screw pin 91 is attached are arranged on the surface of the date jumper 16. Then, the screw 17 is inserted from the surface side of the date dial holder 30 to fix the date jumper 16 and the date dial holder 30 to the main plate 3.
At this time, since the screw jumper hole 165 is formed in the date jumper 16 as described above, the date jumper 16 does not engage with the screw pin 91 as shown in FIGS.
On the other hand, in the specification in which the day display and the 24 o'clock display are not performed by the hands, the date jumper 16 is arranged on the surface of the main plate 3 and the date indicator holder 30 is arranged on the surface of the date jumper 16. Then, the screw 17 is inserted from the surface side of the date dial holder 30 to fix the date jumper 16 and the date dial holder 30 to the main plate 3.
As described above, by forming the screw pin clearance hole 165 in the date jumper 16, the date jumper 16 is changed in both the specification in which the screw pin 91 is attached to the date indicator holder 30 and the specification in which the screw pin 91 is not attached. The common day jumper 16 can be used without any problem.

  As described above, according to the present embodiment, the fixing force (rotational torque) of the screw pin 91 is ensured by the flat portion 94 of the screw pin 91 and the flat portion 301 of the deformation hole 300 in the date dial holder 30. The fixing force (extraction force) of the screw pin 91 is secured by the press-fitting hole 500 of the day hand wheel presser seat 56. Therefore, the fixing function of the screw pin 91 can be realized by using the date indicator press 30 and the day hand presser holding seat 56 provided as separate members on the surface side of the base plate 3.

  Even when the date dial holder 30, the day hand wheel presser seat 56, and the screw pin 91 are handled as a whole by the fixing force (withdrawal force) of the day hand wheel presser seat 56 with respect to the screw pin 91 by the press-fitting hole 500, the screw pin 91. Will not come off. Therefore, as an assembly part, the date indicator holder 30, the day hand indicator holding seat 56, and the screw pin 91 can be handled as one part, as in the case where the date indicator holder 30 is used alone.

  In the specification having an additional function of performing day display and 24 o'clock display using hands, the guide positions of the day hand wheel 44 and the 24 hour wheel 62 and the screw tightening position by the screw pin 91 are determined by the date wheel presser 30. Therefore, by fixing the date indicator holder 30 integrated with the day hand wheel pressing seat 56 and the screw pin 91 to the main plate 3, it is possible to provide an additional function of day display and 24 hour display.

On the other hand, in the specification in which the day display and the 24 o'clock display are performed by the day star wheel 40 and the day plate and the date indicator 10 without providing an additional function, the guide position of the day star wheel 40 is determined by the date indicator holder 30. Therefore, by fixing the date indicator holder 30 to the main plate 3, it is possible to perform the day display and the 24 o'clock display using the day star wheel 40, the day plate and the date indicator 10.
Moreover, the common date indicator holder 30 can be used in the specification having the additional function and the specification not having the additional function.
Thus, according to the present embodiment, the date indicator press integrated with the day hand wheel presser seat 56 and the screw pin 91 regardless of whether the specification has an additional function or not. 30 and the single date indicator holder 30 can be similarly handled in the assembly process.

Furthermore, in the present embodiment, the screw pin 91 is inserted from the back side of the date dial holder 30 and pressed into the day hand wheel presser seat 56 to integrate them, and then the date indicator holder 30 is fixed to the main plate 3. .
On the other hand, when the date pin holder 30 is assembled while the screw pin 91 is placed on the surface of the base plate 3 in advance and the flat portion 301 of the screw pin 91 and the deformation hole 300 of the date indicator holder 30 are aligned, The work is difficult because of the extremely small parts.
Therefore, according to the present embodiment, the work of aligning the deformation hole 300 with the screw pin 91, which is an extremely small part, can be eliminated, and the work in the assembly process, after-sales service, and the like is facilitated.
In the present embodiment, an example in which the flat portion 301 of the screw pin 91 is provided in one place has been described, but the effect is the same even if there are a plurality of flat portions 301.

  Further, as shown in FIGS. 8 and 10, the axial thickness of the first collar portion 93 a of the screw pin 91 is formed to be about the thickness of the date jumper 16. By doing in this way, the back surface of the date jumper 16 and the back surface of the 1st collar part 93a can be provided in the substantially same surface. Therefore, at the time of screw tightening, the back surface of the first collar portion 93a comes into contact with the surface of the base plate 3, and backup at the time of screw tightening is performed by the base plate 3. As a result, even when the axial thickness of the first collar portion 93a is about the thickness of the date jumper 16, a highly reliable screw pin holding structure can be achieved.

  Further, as described above, the timepiece 100 is incorporated on the opposite side of the main plate 3 with respect to the date indicator holder 30 in addition to the first vehicle such as the day star wheel 40 and the date indicator driving wheel 15 guided by the main plate 3. The second wheel such as the day hand wheel 44 and the 24 hour wheel 62 is provided. The day hand wheel 44 rotates in conjunction with the day star wheel 40, and the 24-hour wheel 62 rotates in conjunction with the date indicator driving wheel 15, so that a new function can be provided by using the day star wheel 40 or the date indicator driving wheel 15. It becomes possible to add. Here, the day star wheel 40 and the date indicator driving wheel 15 are guided by the main plate 3, while the day hand wheel 44 and the 24-hour wheel 62 are guided by the date indicator holder 30. Therefore, by simply changing the existing date indicator holder so that the day hand wheel 44 and the 24-hour wheel 62 can be guided, a new function can be obtained by using the existing main plate 3, the day star wheel 40, and the date indicator driving wheel 15. Can be added. In other words, the date indicator holder 30 is also made to function as a ground plate for incorporating the day hand wheel 44 and the 24-hour wheel 62, and a mechanism for an additional function is provided in a region opposite to the ground plate 3 with respect to the date indicator holder 30. It can be incorporated.

  Specifically, the date indicator holder 30 is formed with planar guide holes 33, 34, 35 for pivotally supporting the day star intermediate wheel 43, the day hand wheel 44, and the 24-hour wheel 62, and the day star intermediate wheel 43, Positioning of the day hand wheel 44 and the 24-hour wheel 62 in the axial direction is performed by a day hand wheel presser 55. The day hand wheel presser 55 is positioned in the axial direction by the day hand wheel presser seat 56. Therefore, the additional function structure including the day hand wheel 44 for displaying the calendar other than the date display and the 24-hour wheel 62 for displaying the time is completed by a member on the surface side of the date indicator holder 30 without using the main plate 3. become able to.

  Therefore, even if the calendar and display other than the date display and the layout and configuration of the additional function for displaying the time are changed, only the member on the surface side than the date dial holder 30 may be changed. There is no need to change.

Further, when the screw pin 91 is not attached to the date indicator holder 30, the day star wheel 40 and the day plate and the date indicator 10 are used. When the screw pin 91 is attached, the day hand wheels 44 and 24 are used. An additional function of displaying a pointer by the hour wheel 62 can be provided. In this manner, the two types of structures can be switched depending on the presence or absence of the screw pin 91, and the specification of the day display and the 24 o'clock display can be easily switched including the assembly process.
In other words, it is possible to switch the specification of the day display and the 24 o'clock display in the calendar assembly process, which is the final process of the assembly of the movement 2, and prevent the loss of opportunity of the product due to the schedule until the product delivery. Can do.

  Since the structure of the tooth 41 of the date indicator 10 and the day star wheel 40 can be used as it is, the date feeding claw 151, the day feeding claw 152, the day jumper 16, the day jumper 36, etc. Common use of day feeding structure becomes possible. As a result, even when an additional function such as the day hand wheel 44 and the 24-hour wheel 62 is provided, it is possible to use a common date feeding / day feeding structure with a proven record of failure and destruction, and high reliability. It can be a calendar structure.

  Next, a correction mechanism for the date wheel 10 and the day star wheel 40 in this embodiment will be described.

As shown in FIG. 18, a setting lever 114 a is formed at the tip of the back presser 114. The position in the planar direction of the setting lever 112 is regulated by pressing the setting lever regulating shaft 112c planted on the setting lever 112 by the setting lever regulating portion 114a formed at the tip of the back presser 114. The push-pull position of the winding stem 110 is regulated by mounting the peninsula-shaped setting lever operating portion 112a of the setting lever 112 on the setting mounting portion 110a of the winding stem 110.

  FIG. 19 is a plan view of the yoke 113. The yoke 113 shown in FIG. 19 is swung by the yoke operating portion 112d formed at the end of the setting lever 112 in the clockwise direction around the yoke shaft 113a and by the elastic force of the spring portion 113e in the counterclockwise direction. Is done. The position in the planar direction of the yoke 113 is regulated by the yoke operating portion 112 d of the setting lever 112 coming into contact with the yoke operating portion 113 b of the yoke 113.

  As shown in FIG. 19, a pinion wheel actuating portion 113 c is provided at the front end of the yoke 113, and the pinion wheel actuating portion 113 c engages with the pinion wheel 116 to restrict the position of the pinion wheel 116. doing.

  As shown in FIG. 16, in the axial direction of the winding stem 110, a pinion wheel 116 that can swing and interlocks with the rotation of the winding stem 110 is formed. A small wheel rotating tooth 117 is formed on the pinion wheel 116. The tip of the yoke 113 swings in accordance with the push / pull position of the winding stem 110, and the pinion wheel 116 is moved in the axial direction. In accordance with the movement of the pinion wheel 116, a rotating tooth that meshes with the pinion wheel 116 is selected.

  A small iron lever 115 as a swinging member is attached to the lower part (base plate side) of the setting lever 112, the yoke 113, and the back presser 114. FIG. 20 is a plan view of the small iron lever 115. As shown in FIG. 20, the small iron lever 115 is provided with a small iron lever operating hole 115a at one end. On the other hand, a calendar correction swing hole 115b that is engaged with the shaft 120a of the calendar correction wheel 120 is provided.

The small iron lever 115 swings around the small iron lever shaft 115c, but the small iron lever operating shaft 115b engages with the small iron lever operating shaft 112b planted in the setting lever 112, and the position of the swing is regulated. Yes.
As shown in FIG. 20, a small iron wheel 115d and a calendar correction transmission wheel 115e are coaxially supported on the small iron lever 115 so as to be rotatable with the small iron lever 115 interposed therebetween.

  As the small iron lever 115 swings, the calendar correction wheel 120 abuts on the inner wall of the calendar correction swing hole 115b in accordance with the swing of the small iron lever 115 and is swingably provided in the direction of arrow B or arrow C shown in FIG. Yes. When the calendar correction wheel 120 swings in the direction of arrow B, the calendar correction wheel 120 engages with the internal gear 12 of the date dial 10. When the calendar correction wheel 120 swings in the direction of arrow C, the calendar correction wheel 120 is engaged with the day correction wheel 130. The setting lever 112 swings in accordance with the push / pull position of the winding stem 110, and the yoke 113 swings in response to this, whereby the pinion wheel 116 and the small iron wheel 115d are engaged and the calendar is corrected. . Further, according to this, the yoke 113 and the small iron lever 115 are swung to be in a time correction state.

  In the calendar correction state, by rotating the winding stem 110, the calendar correction transmission wheel 115e rotates via the pinion wheel 116 and the small iron wheel 115d. When the calendar correction transmission wheel 115e rotates and the calendar correction wheel 120 swings in the direction of arrow B, the calendar correction wheel 120 and the internal gear 12 of the date dial 10 are engaged. As a result, the date dial 10 can be corrected. In addition, when the setting lever 112 swings in accordance with the push / pull position of the winding stem 110 and the small iron lever 115 swings in response thereto, the calendar correction wheel 120 swings in the direction of arrow C, The calendar correction wheel 120 and the day correction wheel 130 are engaged. Since the day corrector wheel 130 is engaged with the day star wheel 40, the day star wheel 40 can be corrected.

  21 is a cross-sectional view taken along line V-V ′ in FIG. 16, and FIG. 22 is a cross-sectional view taken along line IV-IV ′ in FIG. 16. As shown in FIGS. 21 and 22, the correction mechanism described above is provided on the back side of the date jumper 16 or on the surface of the ground plane 3 in the same manner as the date jumper 16. Therefore, not only the structure of the tooth 41 of the date indicator 10 and the day star wheel 40, but also the date feeding / day feeding structure such as the date feeding claw 151, the day feeding claw 152, the date jumper 16, and the day jumper 36, as well as the correction mechanism. However, it can be used in common with the prior art. As a result, even when additional functions such as the day hand wheel 44 and the 24-hour wheel 62 are provided, a mechanism that has a proven record for failure and destruction can be commonly used as a correction mechanism that is particularly complicated and difficult to set. As a result, a highly reliable calendar correction structure can be realized. For example, even when using a day plate that is pivotally supported by the day star wheel 40 without using the day hand wheel 44, it is only necessary to change the layout and configuration on the surface side of the date wheel holder 30, and the correction mechanism is common. The correction mechanism can be used. FIG. 23 is a cross-sectional view showing the position of the day plate. As shown in FIG. 23, the day plate is supported and positioned by a member on the surface side of the date dial holder 30. Therefore, a common correction mechanism can be used not only for the date feeding / day feeding structure but also for the correction mechanism.

Second Embodiment
A second embodiment of the present invention will be described with reference to FIG. FIG. 24 is a perspective view showing the configuration of the date dial holder 30 in the present embodiment. As shown in FIG. 24, in this embodiment, a bush 96 is integrally formed with the date dial holder 30 as a fixing member. As in the first embodiment, the screw pins 91 are inserted at positions corresponding to the three deformation holes 300 of the date dial holder 30. A bush 96 serving as a positioning member for the day hand wheel presser 55 is press-fitted into the outer periphery of the cylindrical portion of each screw pin 91. The bush 96 is used as a member that replaces the day wheel presser seat 56 in the first embodiment. That is, in the present embodiment, the day hand wheel presser seat 56 is not used.

The pulling force of the bush 96 is ensured by press-fitting into the screw pin 91. The axial thickness of the bush 96 functions as the axial positioning of the day hand wheel presser 55, and the day hand wheel presser 55 is positioned in the axial direction by screwing the screw 90 onto the screw pin 91. Therefore, by using the bush 96, the same effect as that of the day hand wheel presser seat 56 of the first embodiment can be obtained.
Since the bush 96 can have a simple cylindrical shape, it is easy to process, and parts can be prepared at low cost and in a short period of time.

  Also in this embodiment, the date indicator press 30 is formed with the day star intermediate wheel 43, the day hand wheel 44, and the plane guide holes 33, 34, 35 for pivotally supporting the 24 hour wheel, and the day star intermediate wheel. 43, the day hand wheel 44, and the 24 hour wheel are positioned in the axial direction by the day hand wheel presser 55. The day hand wheel presser 55 is positioned in the axial direction by the day hand wheel presser seat 56. Therefore, the additional function structure including the day hand wheel 44 for displaying the calendar other than the date display and the 24-hour wheel 62 for displaying the time is completed by a member on the surface side of the date indicator holder 30 without using the main plate 3. become able to.

  Therefore, even if the calendar and display other than the date display and the layout and configuration of the additional function for displaying the time are changed, only the member on the surface side than the date dial holder 30 may be changed. There is no need to change.

  Since the structure of the tooth 41 of the date indicator 10 and the day star wheel 40 can be used as it is, the date feeding claw 151, the day feeding claw 152, the day jumper 16, the day jumper 36, etc. Common use of day feeding structure becomes possible. In addition, the correction mechanism described above can be used in common. As a result, even when an additional function such as the day hand wheel 44 and the 24-hour wheel 62 is provided, it is possible to use a date feeding / day feeding structure and a correction mechanism that have a proven record of failure and destruction, and reliability is improved. A high calendar structure can be obtained.
