Description

The present invention relates to a display correction mechanism, an information display mechanism, a movement and a timepiece.

2. Description of the Related Art Conventionally, clocks are known which have an information display mechanism for displaying information other than the time, such as the day of the week, date, age of the moon, and the like. A timepiece equipped with this type of information display mechanism generally has a correction mechanism for correcting various types of displayed information as necessary.
For example, Patent Literature 1 below discloses a correction mechanism (correction mechanism) for correcting a date indicator that displays the date and a month indicator that displays the age of the moon.

The correction mechanism includes a swing plate that swings around the swing axis as the winding stem rotates through the crown, a correction wheel that is pivotally supported by the swing plate, and a correction wheel that is provided on the swing plate. and a plurality of transmission wheels for transmitting power (rotational torque) from the winding stem to the winding stem.
The rocking plate rotates about the rocking axis so as to move to either the first position or the second position depending on the direction of rotation of the winding stem. The correction wheel can mesh with the internal teeth of the date wheel when the rocking plate is positioned at the first position, and can mesh with the intermediate wheel which meshes with the month wheel when the rocking plate is positioned at the second position. It is said that

As a result, by rotating the winding stem in one direction, the rocking plate can be moved to the first position, and the power transmitted from the plurality of transmission wheels is used to rotate the correction wheel, thereby driving the date wheel. Correction is possible. Further, by rotating the winding stem in the other direction, the rocking plate can be moved to the second position. It becomes possible to modify the moon wheel.

JP 2015-219240 A

However, in the above-described conventional correction mechanism, it is necessary to assemble a correction wheel for correcting the date wheel and the month wheel and a plurality of transmission wheels for transmitting power to the correction wheel to the swing plate. Scores are high and there is room for improvement.
Furthermore, since the date wheel and the month wheel are each corrected using one correction wheel provided on the swing plate, the date wheel can be directly rotated using the correction wheel. Although it can be rotated, it is difficult to rotate without interposing intermediate wheels (one or more) with respect to the month wheel. Therefore, also in this point, the number of parts increases.
In addition, because it is necessary to incorporate an intermediate wheel, the movement tends to become thicker in the thickness direction, which hinders the reduction in thickness and size of the watch.

The present invention has been made in consideration of such circumstances, and its object is to enable display correction to be performed appropriately while reducing the number of parts, and to achieve display correction that can be made smaller and thinner. To provide a mechanism, an information display mechanism, a movement and a timepiece.

(1) A display correcting mechanism according to the present invention includes a swing lever that is swingable about a swing axis and displaces between a first correcting position and a second correcting position, and a swing lever that is separated from the swing axis. It is rotatable about a coaxial first rotation axis and is arranged so as to be able to approach and separate from a first display wheel on which first information is displayed, and the rocking lever rocks to the first correction position. A first correction wheel that approaches the first indicator wheel by the rocking lever and meshes with the first indicator wheel when the rocking lever is engaged with the first indicator wheel, and a second rotation axis that is not coaxial with the rocking axis and the first rotation axis. It is rotatable around and arranged so as to be able to approach and separate from a second display wheel displaying second information, and when the rocking lever is rocked to the second correction position, the rocking lever is rotated to the second correction position. A second correction wheel that approaches the second display wheel by a movement lever and meshes with the second display wheel, and rotates around the swing axis in a state of meshing with the first correction wheel and the second correction wheel. a correction transmission wheel arranged removably for transmitting power transmitted from the outside to the first correction wheel and the second correction wheel, wherein the correction transmission wheel, the first correction wheel and the second correction wheel at least one of the wheels is combined with the rocking lever while having a predetermined rotational resistance between itself and the rocking lever, and the rocking lever rotates as the correction transmission wheel rotates. and when it is positioned at the first correction position and the second correction position and receives a resistance exceeding the rotational resistance, any one of the swing levers It is characterized by allowing relative rotation of the car.

According to the display correcting mechanism of the present invention, by rotating the correcting transmission wheel with power transmitted from the outside, it is possible to swing the rocking lever about the rocking axis along with the rotation of the correcting transmission wheel. , to a first correction position or a second correction position.

By swinging the rocking lever toward the first correction position, the first correction wheel can be brought closer to the first display wheel and meshed with the first correction wheel. It should be noted that the first correction wheel does not mesh with the first display wheel until the rocking lever moves to the first correction position, and moves while rotating with the rotation of the correction transmission wheel.
By meshing with the first display wheel, the first correction wheel can transmit the power transmitted from the correction transmission wheel to the first display wheel, so that the first display wheel can be rotated. As a result, it is possible to correct the display of the first display vehicle on which the first information is displayed. Note that when the rocking lever moves to the first correction position, it is positioned at the first correction position, so further movement is restricted. Therefore, the rocking lever receives resistance exceeding the rotational resistance, and the correction transmission wheel and the first correction wheel can be rotated while the position of the rocking lever remains unchanged. As a result, it is possible to appropriately correct the display of the first display vehicle.

Contrary to the case described above, by swinging the rocking lever toward the second correction position, the second correction wheel can be brought closer to the second display wheel and meshed with the second correction wheel. can. It should be noted that the second correction wheel does not mesh with the second display wheel until the rocking lever moves to the second correction position, and moves while rotating with the rotation of the correction transmission wheel.
By meshing with the second display wheel, the second correction wheel can transmit the power transmitted from the correction transmission wheel to the second display wheel, so that the second display wheel can be rotated. As a result, the display of the second display vehicle on which the second information is displayed can be corrected. Note that when the rocking lever moves to the second correction position, it is positioned at the second correction position, so further movement is restricted. Therefore, the rocking lever receives resistance exceeding the rotational resistance, and the correction transmission wheel and the second correction wheel can be rotated while the position of the rocking lever remains unchanged. As a result, it is possible to appropriately correct the display of the second display vehicle.

By swinging the swing lever in this way, two correction wheels having different rotation axes, that is, the first correction wheel and the second correction wheel can be moved in conjunction with each other. The two display wheels can be directly meshed to correct the display. Therefore, it is not necessary to correct the display of the first display wheel or the second display wheel via an intermediate wheel or the like, unlike the conventional art, and the number of parts can be reduced. Therefore, the display correcting mechanism can be configured simply, and the cost can be reduced.

Furthermore, since the correction transmission wheel to which power is transmitted from the outside can be used to swing the rocking lever, the correction transmission wheel is meshed with the first correction wheel and the second correction wheel. Power can be transmitted directly from the correction transmission wheel to the first correction wheel and the second correction wheel. Therefore, also in this respect, the number of parts can be effectively suppressed.
Furthermore, since it is not necessary to correct the first display wheel or the second display wheel via an intermediate wheel or the like as described above, there is no need to secure a space for arranging the intermediate wheel. Therefore, it is easy to achieve miniaturization and thinning.
Furthermore, since the first correction wheel and the second correction wheel can be directly meshed with the first indicator wheel and the second indicator wheel, it is easy to design the first correction wheel and the second correction wheel. That is, since the first correction wheel meshes only with the correction transmission wheel and the first display wheel, it is possible to have two meshing points, and the tooth profile and the like can be easily and freely designed. Similarly, since the second correction wheel is also meshed only with the correction transmission wheel and the second display wheel, it is possible to have two meshing points and easily and freely design the tooth profile. Therefore, the degree of freedom in designing the first correction wheel and the second correction wheel can be improved.

(2) The first correction wheel may be rotatably supported by the swing lever about the first rotation axis.

In this case, the first correction wheel can be moved in accordance with the rocking motion of the rocking lever. can be moved closer together. Therefore, when the rocking lever is positioned at the first correction position, the first correction wheel can be properly meshed with the first display wheel. Therefore, it is easier to more reliably correct the display of the first display vehicle. Furthermore, since the rocking lever and the first correction wheel can be combined integrally, the work of assembling the display correction mechanism can be easily and efficiently performed.

(3) The first correction wheel is guided toward and away from the first display wheel along the guide groove, and the swing lever swings toward the first correction position. , the first correction wheel may be pushed closer to the first display wheel.

In this case, since the first correction wheel can be guided along the guide groove formed in the main plate or the like, the posture of the first correction wheel can be easily stabilized, and the rocking lever can be swung to the first correction position. Along with this, the first correction wheel can be stably moved toward the first display wheel. Therefore, the first correction vehicle can be more reliably meshed with the first display vehicle, and the display can be easily corrected.

(4) The swing lever is formed with an insertion hole through which the axle of the first correction wheel is inserted. When the inner edge is used to press the first correction wheel toward the first display wheel and swing toward the second correction position, the inner edge of the insertion hole is used. The first correction wheel may be pushed away from the first display wheel.

In this case, even when the rocking lever is rocked toward either the first correction position or the second correction position, the insertion hole can be used to push the first correction wheel, so that the first display is not displayed. Engagement by approaching the car and disengagement by separating from the first display car can be more reliably performed.

(5) The second correction wheel may be rotatably supported by the swing lever about the second rotation axis.

In this case, the second correction wheel can be moved in accordance with the rocking motion of the rocking lever. can be moved closer together. Therefore, when the rocking lever is positioned at the second correction position, the second correction wheel can be appropriately meshed with the second display wheel. Therefore, it is easier to more reliably correct the display of the second display vehicle. Furthermore, since the rocking lever and the second correction wheel can be combined integrally, the work of assembling the display correction mechanism can be easily and efficiently performed. In particular, when the first correction wheel is integrally combined with the rocking lever, the work of assembling the display correction mechanism can be performed more efficiently.

(6) The correction transmission wheel is rotatable about the swing axis in the first direction or the second direction as the winding stem rotates, and the swing lever rotates the correction transmission wheel in the first direction. When the correction transmission wheel is rotated in the second direction, it may swing toward the first correction position, and when the correction transmission wheel rotates in the second direction, the correction transmission wheel may swing toward the second correction position.

In this case, by rotating the winding stem, the display of the first display wheel or the second display wheel can be arbitrarily selected and separately corrected, so that the correction work can be easily performed. Easy to use.

(7) An information display mechanism according to the present invention includes the display correction mechanism, the first display wheel, and the second display wheel.

According to the information display mechanism of the present invention, since the display correction mechanism described above is provided, it is possible to appropriately correct the display of the first display wheel and the second display wheel as necessary. Furthermore, the information display mechanism can be made smaller and thinner, and can be easily incorporated into a movement or the like.

(8) The first display wheel is a date wheel that displays date characters as the first information, and the second display wheel is equipped with a 24-hour hand that displays a second time zone as the second information. A 24-hour hour wheel may be used.

According to the information display mechanism of the present invention, it is possible to appropriately display the date characters and to appropriately display the second time zone using the 24-hour hand. Therefore, it is possible to appropriately display the date, time, etc. of two countries (cities) that differ due to, for example, the time difference.

(9) A movement according to the present invention includes the information display mechanism.
(10) A timepiece according to the present invention includes the movement described above.

In this case, since the information display mechanism described above is provided, the first information and the second information can be displayed appropriately, high quality and high performance can be achieved, and furthermore, miniaturization and thinning can be achieved. It can be a movement and a watch.

(First embodiment)
A first embodiment according to the present invention will be described below with reference to the drawings.
In this embodiment, as an example of a timepiece, in addition to the hour hand, minute hand and second hand, the 24-hour hand (secondary hour hand) is arranged at the center of the movement. explain. In addition, in each drawing of the present embodiment, in order to make the drawings easier to see, there are cases where illustration of some watch parts is omitted, and there are cases where each watch part is shown in a simplified form. .

In general, the mechanical body including the driving part of the watch is called "movement". A dial and hands are attached to this movement, and it is called a "complete" watch when it is placed in a watch case. Of the two sides of the main plate that constitutes the substrate of the watch, the side on which the glass of the watch case is located (that is, the side on which the dial is located) is referred to as the "back side" of the movement. Of the two sides of the main plate, the side on which the case back of the watch case is located (that is, the side opposite to the dial) is referred to as the "front side" of the movement.

In the embodiments, the direction from the case back cover side (front side) to the dial is defined as the upper side, and the opposite side is defined as the lower side. Therefore, the thickness direction of the base plate is the vertical direction. Further, in the present embodiment, the direction of clockwise rotation as viewed from above is referred to as the clockwise direction, and the direction of counterclockwise rotation as viewed from above is referred to as the counterclockwise direction about each axis.

As shown in FIG. 1, the complete watch 1 of the present embodiment includes a movement (watch movement) 10 and at least a scale indicating information about time, etc., in a watch case 3 consisting of a case back cover and a glass 2 (not shown). and various pointers for indicating the scale of the dial 4.
The hands are the 24-hour hand 5, which rotates once every 24 hours to indicate the hour in 24-hour format, the hour hand 6, which rotates once in 12 hours to indicate the hour in 12-hour format, and the minute hand, which rotates once in 60 minutes to indicate the minute. and a second hand 8 rotating once every 60 seconds to indicate the seconds.
The dial 4 is provided with a date window 4a through which a date character 9 displayed on a date indicator 50, which will be described later, is displayed. As a result, the clock 1 of this embodiment can display the date in addition to the time.

As shown in FIGS. 1 to 4, the movement 10 has a main plate 11 forming a substrate of the movement 10. As shown in FIGS.
On the front side of the main plate 11, at least a front train wheel, an escapement for controlling rotation of the front train wheel, and a speed governor for controlling the speed of the escapement are arranged. In each drawing, illustration of an escapement and a speed governor is omitted.
A dial plate 4 (see FIG. 1) is arranged on the back side of the main plate 11, and between the dial plate 4 and the main plate 11 are a cannon pinion 21, a date wheel (not shown), a hose wheel 24 and 24 o'clock. At least the back train wheel including the hour wheel 40, the information display mechanism 12, and the display correction mechanism 13 are arranged. Note that the dial plate 4 is arranged so as to be visible through the glass 2 .

The front train wheel is arranged between the train wheel bridge (not shown) arranged on the front side of the main plate 11 and the main plate 11, and is rotated by the output torque accompanying the unwinding of the mainspring (not shown). 7 and the second hand 8 are played. The front train wheel mainly includes a barrel wheel, a second wheel & pinion 17 (see FIG. 4), a third wheel & pinion and a fourth wheel & pinion 20 . In each drawing, illustration of a barrel wheel and a third wheel is omitted.
A mainspring (not shown) that is wound up via the crown 14 and the winding stem 15 shown in FIG. 1 is housed inside the barrel wheel. The barrel wheel rotates due to the elastic restoring force that accompanies the unwinding of the mainspring. The center wheel & pinion 17, the third wheel & pinion and the fourth wheel & pinion 20 rotate in order as the barrel wheel rotates.

The fourth wheel & pinion 20 is arranged coaxially with a central axis line C passing through the center of the movement 10 . The axle of the fourth wheel & pinion 20 protrudes from the dial plate 4 toward the glass 2, and the second hand 8 is attached to its upper end. As a result, the second hand 8 is driven directly by the rotation of the second wheel & pinion 20, which is a direct drive system. Therefore, the second hand 8 shown in FIG. 1 rotates around the central axis C based on the rotation of the second wheel & pinion 20, and rotates once in 60 seconds, at a rotational speed controlled by the escapement and governor. .

The escapement has an escape wheel that meshes with the fourth wheel & pinion 20 and is rotated by the power transmitted from the mainspring, and an anchor that causes the escape wheel to escape and rotate regularly. to control the front wheel train. The governor mainly uses a hairspring (not shown) as a power source, and has a balance that reciprocates (rotates forward and backward) with a steady amplitude (swing angle) corresponding to the output torque of the barrel wheel.

As shown in FIG. 4, the cannon pinion 21 constituting the back train wheel is arranged coaxially with the central axis C on the back side (above) of the main plate 11 and is rotatable around the central axis C. The cannon pinion 21 has a cannon pinion main body 22 and is combined with the center wheel & pinion 17 while maintaining a predetermined pressure contact force (frictional force). As a result, the cannon pinion 21 is rotatable about the center axis C as the center wheel & pinion 17 rotates.
When a relative rotational force exceeding the pressure contact force (frictional force) acts between the cannon pinion main body 22 and the center wheel & pinion 17, such as when setting the time, for example, the cannon pinion does not move against the center wheel & pinion 17. 21 can be slipped.

The upper end portion of the cannon pinion main body 22 protrudes above the hour wheel 24 and is arranged below the upper end portion of the axle of the fourth wheel & pinion 20 . A minute hand 7 is attached to the upper end portion of the cannon pinion main body 22 . Therefore, the minute hand 7 is positioned closer to the dial 4 than the second hand 8 attached to the second wheel & pinion 20 . As a result, it is possible to directly move the minute hand 7 by rotating the cannon pinion 21 . The minute hand 7 rotates once in 60 minutes at a rotational speed controlled by the escapement and governor.

The hour wheel 24 that constitutes the back train wheel is arranged coaxially with the central axis C on the back side of the main plate 11 and is rotatable around the central axis C. As shown in FIG. The hour wheel 24 includes a cylindrical hour wheel body 25 surrounding the cylinder pinion body 22, and a cylindrical gear 26 integrally formed at the lower end of the hour wheel body 25 and meshing with the pinion.

A minute wheel (not shown) is pivotally supported between the main plate 11 and the back presser 16 arranged between the dial 4 and the main plate 11 . The minute wheel has a minute pinion meshing with the cylindrical pinion 26 and a minute pinion meshing with the cylindrical pinion 21. - 特許庁Therefore, the minute wheel is meshed with both the cannon pinion 21 and the hour wheel 24 .
As a result, the hour wheel 24 is rotatable about the central axis C as the cannon pinion 21 and the minute wheel 21 rotate. Further, the upper end portion of the hour wheel main body 25 protrudes above the dial 4 and is arranged below the upper end portion of the main body 22 of the cannon pinion. The hour hand 6 is attached to the upper end portion of the hour wheel main body 25 .

Therefore, the hour hand 6 is positioned closer to the dial 4 than the minute hand 7 attached to the pinion 21 . As a result, it is possible to directly move the hour hand 6 by rotating the hour wheel 24 . The hour hand 6 rotates once in 12 hours at a rotational speed controlled by the escapement and governor.

The minute wheel is linked to the winding stem 15 when the winding stem 15 shown in FIG. As a result, the minute wheel is continuously rotated in accordance with the rotation of the winding stem 15 when the winding stem 15 is positioned at the second stage position.

A 24-hour intermediate wheel 30 shown in FIGS. 2 and 3 meshes with the cylindrical gear 26 described above.
The 24-hour intermediate wheel 30 is rotatably supported around the axis M mainly by the main plate 11 . As shown in FIG. 5 , the 24-hour intermediate wheel 30 includes a 24-hour intermediate gear 31 meshing with the cylinder gear 26 and a 24-hour intermediate pinion 32 . As a result, the 24-hour intermediate wheel 30 rotates about the axis M as the hour wheel 24 rotates.

(24 hour cylinder wheel)
As shown in FIGS. 3 to 6, the 24-hour hour wheel 40 is arranged coaxially with the center axis C and is rotatable around the center axis C. As shown in FIGS.
The 24-hour hour wheel 40 is formed in a cylindrical shape and includes a 24-hour cannon pinion 41 surrounding the hour wheel main body 25, a 24-hour gear 42 integrally combined with the 24-hour cannon pinion 41, and the 24-hour cannon pinion 41. and a 24-hour cylinder gear 43 that surrounds it.

The 24-hour cannon pinion 41 projects upward from the dial plate 4 at its upper end and is arranged below the upper end of the hour wheel main body 25 . A 24-hour hand 5 is attached to the upper end of the 24-hour cannon pinion 41 .
Therefore, the 24-hour hand 5 is located closer to the dial 4 than the hour hand 6 is. As a result, it is possible to directly move the 24-hour hand 5 by rotating the 24-hour hour wheel 40 . The 24-hour hand 5 rotates once in 24 hours at a rotational speed controlled by the escapement and governor.

As shown in FIG. 6, an hour jumper pinion 45 having a plurality of radially projecting jumper teeth 45a is formed below the 24-hour gear 42 at the lower end of the 24-hour cannon pinion 41 . A plurality of jumper teeth 45 a are formed at regular intervals along the entire circumference of the 24-hour cannon pinion 41 . In the illustrated example, there are 24 jumper teeth 45a.

As shown in FIGS. 5 and 6, the 24-hour gear 42 is integrally combined with the 24-hour cannon pinion 41 by, for example, press fitting. As a result, the 24-hour cannon pinion 41 and the 24-hour gear 42 are always synchronously rotatable about the center axis C. As shown in FIG.

As shown in FIG. 6, the 24-hour cylinder pinion 43 is arranged coaxially with the central axis C, and has an insertion hole 46 formed in its central portion through which the entire 24-hour cylinder pinion 41 including the hour jumper pinion 45 is inserted. It is Thus, the 24-hour cylinder gear 43 is arranged to surround the hour jumper pinion 45 with the 24-hour cylinder pinion 41 inserted into the insertion hole 46 .
Note that the plurality of jumper teeth 45 a are in sliding contact with the inner peripheral surface of the insertion hole 46 . As a result, the 24-hour cannon pinion 41 and the 24-hour canister gear 43 are combined so as to be relatively rotatable about the center axis C and not relatively displaceable in the radial direction.

The 24-hour cylinder gear 43 is further formed with a housing hole 48 that passes through the 24-hour cylinder gear 43 and houses the hour jumper 47 inside. The storage hole 48 is formed so as to communicate with the insertion hole 46 .
The hour jumper 47 is elastically deformable in the radial direction, and is formed in the shape of a cantilevered lever whose base end 47 a is connected to the inner peripheral surface of the insertion hole 46 . The hour jumper 47 is arranged inside the housing hole 48 and positioned in the same plane as the plurality of jumper teeth 45a.

The hour jumper 47 extends along the circumferential direction of the 24-hour cannon pinion 41 from a base end portion 47a, and has a jumper at its distal end portion that releasably engages the jumper teeth 45a from the outside in the radial direction. A control claw portion 47b is formed. The jump restraint pawl portion 47b is pressed against the hour jumper pinion 45 by the restoring force associated with the elastic restoration deformation of the hour jumper 47, and is engaged with the jumper teeth 45a.

As a result, the 24-hour cylinder gear 43 is combined with the 24-hour cylinder pinion 41 in a state in which the jump restraint pawl portion 47b of the hour jumper 47 is engaged with the jumper tooth 45a. As a result, the rotation force of the 24-hour cylinder gear 43 can be transmitted to the 24-hour cylinder pinion 41 by the engagement of the jump restraint pawl portion 47b with the jumper tooth 45a of the hour jumper pinion 45, and the 24-hour cylinder gears 43 and 24 The time barrel pinion 41 can be interlocked and rotated.

As shown in FIGS. 5 and 6, the 24-hour cylinder gear 43 meshes with the 24-hour intermediate pinion 32 . As a result, the 24-hour hour wheel 40 rotates as the hour wheel 24 rotates via the 24-hour intermediate wheel 30 . In particular, the 24-hour hour wheel 40 is connected to the hour wheel 24 via the 24-hour intermediate wheel 30 so that the gear ratio of the hour wheel 24 is, for example, 1/2. Thereby, as described above, the 24-hour hour wheel 40 and the 24-hour hand 5 can be rotated once in 24 hours.

When a predetermined torque acts between the 24-hour cylinder pinion 41 and the 24-hour cylinder gear 43, the hour jumper 47 is elastically deformed so as to be separated from the hour jumper pinion 45, and the jump restraining pawl against the jumper tooth 45a. 47b is disengaged. As a result, the 24-hour cylinder pinion 41 and the 24-hour cylinder gear 43 can be relatively rotated while causing the hour jumper 47 to slip with respect to the hour jumper pinion 45 .

However, the jump control pawl portion 47b is a jumper tooth so as to allow relative rotation of the 24-hour cannon pinion 41 in one direction with respect to the 24-hour cannon gear 43 and to restrict rotation of the 24-hour cannon pinion 41 in the other direction. 45a may be engaged. Therefore, the hour jumper 47 may have a so-called ratchet function that restricts rotation in only one direction. In this case, the hour jumper 47 allows the 24-hour cylinder pinion 41 to rotate relative to the 24-hour cylinder gear 43 in the direction in which the 24-hour cylinder wheel 40 rotates by normal hand movement. This makes it possible to rotate the 24-hour gear 42 and the 24-hour cannon pinion 41 to independently correct the 24-hour hand 5 .

(Information display mechanism)
As shown in FIGS. 2 and 3, the information display mechanism 12 is a mechanism for displaying information other than the time, and is a date wheel (first display wheel according to the present invention) that displays date characters 9 as first information. 50, a 24-hour hour wheel (second display wheel according to the present invention) 40 to which a 24-hour hand 5 that displays a second time zone as second information is attached, and these date indicator 50 and 24-hour hour wheel 40 are corrected. A display correcting mechanism 13 is provided.
Therefore, the 24-hour hour wheel 40 described above constitutes the back train wheel of the timepiece 1 and also functions as the information display mechanism 12 in this embodiment.

The date wheel 50 is a ring-shaped member rotatably arranged on the upper surface of the main plate 11, and date characters 9 (date information) representing the days 1 to 31 are indicated in order on the upper surface along the circumferential direction. It is Incidentally, as a method of indicating the day character 9, for example, printing, engraving, attachment of a sticker, etc. can be mentioned, but it is not particularly limited.
In addition, in each drawing other than FIG. 2, illustration of the day character 9 may be omitted.

The date dial 50 is rotatable clockwise as indicated by arrow K in FIG. 2 when viewed from above (the dial 4 side). Therefore, the date can be advanced by rotating the date wheel 50 clockwise.
However, the rotation direction of the date indicator 50 is not limited to the above-described case, and for example, the date indicator 50 may rotate counterclockwise to advance the date.

A plurality of internal teeth 51 are formed along the entire circumference of the inner peripheral edge of the date dial 50 at equal intervals in the circumferential direction. The number of internal teeth 51 is, for example, 31 teeth. Therefore, by rotating the date wheel 50 by one tooth of the inner tooth 51, the date character 9 displayed through the date window 4a can be advanced by one day.
However, the number of internal teeth 51 is not limited to 31, and may be changed as appropriate, such as 62, for example. In this case, the amount of rotation of the date dial 50 for one day may be appropriately changed according to the number of internal teeth 51 .

The date wheel 50 configured as described above is linked to the hour wheel 24 via a date wheel train (not shown), and rotates as the hour wheel 24 rotates. That is, when the hour wheel 24 rotates once in 12 hours, the date wheel 50 rotates by one tooth in one day (24 hours) and rotates around the central axis C once in 31 days. Further, the date wheel 50 has its rotational position regulated by a date jumper (regulating member) (not shown), and by rotating it by one tooth, the date indicator 9 can be advanced by one day. there is

As shown in FIG.

The calendar correction wheel 70 is separated from the date dial 50 and disengaged from the internal teeth 51 when the rocking lever 60 is positioned at the standby position P0 and the second correction position P2. . The 24-hour correction wheel 80 is separated from the 24-hour gear 42 and disengaged from the 24-hour gear 42 when the rocking lever 60 is positioned at the standby position P0 and the first correction position P1. ing.
2 and 3, the standby position P0 is a state in which both the calendar correction wheel 70 and the 24-hour correction wheel 80 are separated from the date indicator 50 and the 24-hour gear 42, and meshing is free. It is the position where

The correction transmission wheel 90 is arranged rotatably around the swing axis N while being meshed with the calendar correction wheel 70 and the 24-hour correction wheel 80, respectively. It plays a role of transmitting to the correction wheel 80 .
As shown in FIGS. 9 and 10, the correction transmission wheel 90 includes a first correction transmission wheel 91 arranged below the swing lever 60 and a first correction transmission wheel 91 arranged above the swing lever 60. and a second correction transmission wheel 92 integrally combined with.

The display correction mechanism 13 will be explained in detail.
As shown in FIGS. 11 and 12, the rocking lever 60 is arranged above the backing presser 16 and formed in the shape of a thin plate. The swing lever 60 includes a swing lever main body 61 having an inner end portion 61a positioned on the 24-hour hour wheel 40 side and an outer end portion 61b positioned on the date indicator 50 side. and a formed lever spring 62 .

A first connecting hole 63 for attaching a calendar correction wheel 70 is formed in the outer end portion 61b of the swing lever body 61 . A first fixing pin 64 is fixed to the first connecting hole 63 by press fitting or the like. The calendar correction wheel 70 is rotatably attached to the first fixing pin 64 while overlapping the upper surface of the rocking lever body 61 . As a result, the calendar correcting wheel 70 is rotatable about the first rotation axis O<b>1 while being retained by the first fixing pin 64 .
Accordingly, in this embodiment, the calendar correction wheel 70 is assembled to the rocking lever 60 and rotatably supported by the rocking lever 60 .

A second connecting hole 65 for mounting a 24-hour correction wheel 80 is formed in the inner end portion 61a of the swing lever body 61 . A second fixing pin 66 is fixed to the second connecting hole 65 by press fitting or the like. The 24-hour correction wheel 80 is rotatably attached to the second fixing pin 66 while overlapping the upper surface of the rocking lever body 61 . As a result, the 24-hour correction wheel 80 is rotatable about the second rotation axis O2 while being retained by the second fixing pin 66 .
Therefore, in this embodiment, the 24-hour correction wheel 80 is assembled to the rocking lever 60 and rotatably supported by the rocking lever 60 .

The lever spring 62 is formed in a cantilever shape connected to the inner end portion 61 a of the swing lever body 61 . The base end of the lever spring 62 is connected to the inner end 61a of the swing lever main body 61, and is formed from the base end to the tip end. The lever spring 62 is elastically deformable, and is urged so that its distal end always approaches the rocking lever main body 61 side by elastic restoring deformation.

The rocking lever 60 configured as described above is configured such that the coupling shaft 93 constituting the correction transmission wheel 90 is sandwiched (clipped) between the rocking lever main body 61 and the tip of the lever spring 62 . It is attached to the connecting shaft 93 . Note that the center axis of the connecting shaft 93 is the pivot axis N. As shown in FIG.
Therefore, in this embodiment, the swing lever 60 and the correction transmission wheel 90 are combined with a predetermined rotational resistance. As a result, the swing lever 60 can swing about the swing axis N with the rotation of the correction transmission wheel 90 unless it receives a resistance exceeding the rotational resistance. On the other hand, the rocking lever 60 allows the correction transmission wheel 90 to rotate relative to the rocking lever 60 when it receives resistance exceeding the rotational resistance.

The second fixing pin 66 that attaches the 24-hour correction wheel 80 to the rocking lever 60 is formed to extend downward from the rocking lever 60, and as shown in FIGS. It is inserted into a guide groove 100 formed in the retainer 16 . 13, illustration of the rocking lever 60 and the 24-hour correction wheel 80 is omitted.
The guide groove 100 is formed so as to extend in the circumferential direction around the swing axis N, and communicates with the main guide groove 101 and extends in the radial direction around the swing axis N. and a formed auxiliary guide groove 102 . In the illustrated example, the main guide groove 101 and the auxiliary guide groove 102 are connected so that the guide groove 100 has an L shape in plan view. However, the present invention is not limited to this case. For example, the main guide groove 101 and the auxiliary guide groove 102 may be connected so that the guide groove 100 has a T shape in plan view. In any case, the guide groove 100 is not limited to a specific shape.

The second fixing pin 66 moves within the main guide groove 101 as the swing lever 60 swings. As a result, the rocking motion of the rocking lever 60 about the rocking axis N can be stabilized, and the 24-hour correction wheel 80 can be stabilized with less rattling.
The second fixing pin 66 comes into contact with the first circumferential end of the main guide groove 101 to which the auxiliary guide groove 102 is connected when the rocking lever 60 is positioned at the first correction position P1. do. This makes it easy to position the rocking lever 60 at the first correction position P1. The second fixing pin 66 is positioned at the second peripheral end portion of the main guide groove 101, which is located on the 24-hour hour wheel 40 side, when the rocking lever 60 is positioned at the second correction position P2. Contact. This makes it easy to position the swing lever 60 at the second correction position P2.

The auxiliary guide groove 102 is an assembly groove into which the second fixing pin 66 is inserted when the rocking lever 60 is assembled so as to sandwich the connecting shaft 93 of the correction transmission wheel 90 . However, if the second fixing pin 66 can be directly inserted into the main guide groove 101 when the rocking lever 60 is assembled, the auxiliary guide groove 102 may be omitted. Therefore, the auxiliary guide groove 102 is not necessarily required, and may be omitted.

As shown in FIGS. 9 and 10, the correction transmission wheel 90 includes a first correction transmission wheel 91 arranged below the swing lever 60 and a first correction transmission wheel 91 arranged above the swing lever 60. and a second correction transmission wheel 92 integrally combined with.
The first correction transmission wheel 91 is arranged below the swing lever 60 and the backing presser 16 . The first correction transmission wheel 91 has a connecting shaft 93 arranged coaxially with the swing axis N and projecting upward. As described above, the rocking lever 60 is combined via this connecting shaft 93 .
The second correction transmission wheel 92 is arranged above the rocking lever 60 and fixed to the connecting shaft 93 by press fitting or the like. As a result, the correction transmission wheel 90 is rotatable around the swing axis N as a unit of the first correction transmission wheel 91 and the second correction transmission wheel 92 .

As shown in FIGS. 12 and 14, the correction transmission wheel 90 configured as described above is linked to the winding stem 15 via a correction train wheel 110, and as the winding stem 15 rotates, the swing axis changes. It is rotatable around N in the first direction L1 or the second direction L2.

(Makishin)
As shown in FIGS. 12 and 14, the winding stem 15 is rotatably incorporated in a winding stem guide hole 11a formed in the main plate 11. As shown in FIGS. The winding stem 15 is connected to the crown 14 shown in FIG. Therefore, the winding stem 15 can be rotated via the crown 14 .

At the first stage position where the winding stem 15 is pulled out by one stage, for example, from the zero stage position, the winding stem 15 and the first transmission wheel 111 can be connected, and the first transmission wheel 111 can be connected in synchronization with the rotation of the winding stem 15. 111 can be rotated.
At the two-step position where the winding stem 15 is pulled out two steps, for example, it can be linked to the minute wheel via a handwheel (not shown) or the like, so that the time can be adjusted.

(correction gear train)
As shown in FIGS. 12 and 14, the correcting train wheel 110 includes a first transmission wheel 111 linked to the winding stem 15 and a rotation of the first transmission wheel 111 when the winding stem 15 is positioned at the first stage position. a second transmission wheel 112 that rotates with the rotation of the second transmission wheel 112; a third transmission wheel 113 that rotates with the rotation of the second transmission wheel 112; a fourth transmission wheel 114 that rotates with the rotation of the third transmission wheel 113; A fifth transmission wheel 115 that rotates with the rotation of the fourth transmission wheel 114, and a sixth transmission wheel 116 that is arranged coaxially with the fifth transmission wheel 115 and rotates in synchronization with the fifth transmission wheel 115. ing.

These second transmission wheel 112, third transmission wheel 113, fourth transmission wheel 114, fifth transmission wheel 115, and sixth transmission wheel 116 are mainly arranged on the upper surface side of the main plate 11 and are rotatable. Supported. The sixth transmission wheel 116 is arranged above the fifth transmission wheel 115 and meshes with the first correction transmission wheel 91 .

Therefore, by rotating the winding stem 15 in the first stage position, power (rotational torque) can be transmitted to the correction transmission wheel 90 via the correction train wheel 110, and the correction transmission wheel 90 can be rotated. It is possible to rotate around the swing axis N.
In this embodiment, the correction transmission wheel 90 can be rotated in the first direction L1 by rotating the winding stem 15 in the first operation direction F1 shown in FIG. It can be swung toward position P1. On the contrary, by rotating the winding stem 15 in the second operation direction F2 shown in FIG. It can be swung toward the second correction position P2.

(Action of clock)
Next, the action of the timepiece 1 configured as described above will be described.
According to the timepiece 1 of the present embodiment, the power from the mainspring, the escapement, and the speed governor regularly drive the front train wheel and the rear train wheel to rotate the center wheel & pinion 17 and the third wheel & pinion. , the fourth wheel & pinion 20 rotates once every 60 seconds. As a result, the second hand 8 can be rotated once every 60 seconds. At the same time, the cannon pinion 21 rotates once in 60 minutes and the hour wheel 24 rotates once in 12 hours, so that the minute hand 7 can be rotated once in 60 minutes and the hour hand 6 can be rotated once in 12 hours. Furthermore, since the 24-hour hour wheel 40 rotates once every 24 hours, the 24-hour hand 5 can rotate once every 24 hours.
As a result, the time can be properly displayed, and the 24-hour hand 5 can be used to properly display the second time zone.

Furthermore, since the date wheel 50 can be rotated via the date-turning train wheel as the hour wheel 24 rotates, the date wheel 50 can be rotated by one tooth with the force resisting the date jumper at the timing of midnight, for example. can only be rotated. As a result, the date character 9 can be advanced by one day, and the date can be displayed appropriately.

As described above, since the information display mechanism 12 includes the date wheel 50 and the 24-hour hour wheel 40, it is possible to simultaneously display the second time zone information and the date information in addition to the time display. The watch 1 can have a multi-function display function.

Next, the case of correcting the date indicator 50 and the 24-hour indicator 40 will be described.
In this case, the crown 14 is pulled out one step to move the winding stem 15 from the 0th step to the 1st step. Thereby, the winding stem 15 and the first transmission wheel 111 can be connected, and the first transmission wheel 111 can be rotated in synchronization with the rotation of the winding stem 15 . Therefore, as shown in FIG. 12, by rotating the winding stem 15, power can be transmitted to the correction transmission wheel 90 via the correction train wheel 110, and the correction transmission wheel 90 rotates around the swing axis N. can be rotated.

Since the correction transmission wheel 90 and the rocking lever 60 are combined in a state of having a predetermined rotational resistance, by rotating the correction transmission wheel 90, the rocking lever 60 is rotated with the rotation of the correction transmission wheel 90. can be swung around the swing axis N and displaced to the first correction position P1 or the second correction position P2.

For example, by rotating the winding stem 15 in the first operation direction F1 shown in FIG. 12, the correction transmission wheel 90 can be rotated in the first direction L1, thereby moving the swing lever 60 to the standby position shown in FIG. It can be swung from P0 toward the first correction position P1 shown in FIG. Therefore, the calendar correcting wheel 70 can be made to approach the date indicator 50 and mesh with the internal teeth 51 of the date indicator 50 .
Since the calendar correcting wheel 70 is separated from the date indicator 50 until the rocking lever 60 moves from the standby position P0 to the first correcting position P1, it does not mesh with the internal teeth 51 of the date indicator 50. , moves while rotating as the correction transmission wheel 90 rotates.

The calendar correcting wheel 70 meshes with the internal teeth 51 of the date dial 50 to transmit the power transmitted from the correcting transmission wheel 90 to the date dial 50, thereby rotating the date dial 50. - 特許庁As a result, the display of the date indicator 50 can be corrected, and the date can be corrected.
Note that the rocking lever 60 is positioned at the first correction position P1 when moved to the first correction position P1. Specifically, when the rocking lever 60 is positioned at the first correction position P1, the second fixing pin 66 on the side of the 24-hour correction wheel 80 is connected to the auxiliary guide groove 102 of the peripheral end portion of the main guide groove 101. contacting the first peripheral edge. Thereby, the rocking lever 60 is positioned at the first correction position P1. Accordingly, when the rocking lever 60 moves to the first correction position P1, further movement is restricted. Therefore, the rocking lever 60 receives resistance exceeding the rotational resistance, and only the correction transmission wheel 90 can be rotated while the rocking lever 60 remains in the position. As a result, the display of the date indicator 50 can be appropriately corrected.

Contrary to the case described above, for example, by rotating the winding stem 15 in the second operation direction F2 shown in FIG. can be swung from the standby position P0 shown in FIG. 2 toward the second correction position P2 shown in FIG. Therefore, the 24-hour correction wheel 80 can be brought closer to the 24-hour gear 42 and meshed with the 24-hour gear 42 .
Since the 24-hour correction wheel 80 is separated from the 24-hour gear 42 until the rocking lever 60 moves to the second correction position P2, the correction transmission wheel 90 does not mesh with the 24-hour gear 42. It moves while rotating with the rotation of .

The 24-hour correction wheel 80 can transmit the power transmitted from the correction transmission wheel 90 to the 24-hour gear 42 by meshing with the 24-hour gear 42, and can rotate the 24-hour gear 42. - 特許庁Thereby, the display of the 24-hour gear 42 can be corrected, and the 24-hour hand 5 can be corrected.
Note that the rocking lever 60 is positioned at the second correction position P2 when moved to the second correction position P2. Specifically, when the rocking lever 60 is positioned at the second correction position P2, the second fixing pin 66 on the side of the 24-hour correction wheel 80 is positioned on the side of the 24-hour hour wheel 40 in the peripheral end portion of the main guide groove 101. It contacts the located second peripheral edge. As a result, the swing lever 60 is positioned at the second correction position P2. Accordingly, when the rocking lever 60 moves to the second correction position P2, further movement is restricted. Therefore, the rocking lever 60 receives resistance exceeding the rotational resistance, and only the correction transmission wheel 90 can be rotated while the rocking lever 60 remains in the position. As a result, the display of the 24-hour hand 5 can be appropriately corrected.

By swinging the swing lever 60 in this way, two correction wheels having different rotation axes, that is, the calendar correction wheel 70 and the 24-hour correction wheel 80 can be moved in conjunction with each other. The display can be corrected by directly meshing with the 24-hour gear 42 . Therefore, it is not necessary to correct the display of the date wheel 50 or the 24-hour gear 42 via an intermediate wheel or the like, unlike the conventional art, and the number of parts can be reduced. Therefore, the display correction mechanism 13 can be configured simply, and cost reduction can be achieved.

Further, the correction transmission wheel 90 to which power is transmitted through the winding stem 15 can be used to swing the rocking lever 60, and the correction transmission wheel 90 can be used as the calendar correction wheel 70 and the 24-hour correction wheel 80. Since they are meshed, power can be directly transmitted from the correction transmission wheel 90 to the calendar correction wheel 70 and the 24-hour correction wheel 80 . Therefore, also in this respect, the number of parts can be effectively suppressed.

Furthermore, since it is not necessary to correct the date wheel 50 or the 24-hour gear 42 via an intermediate wheel or the like as described above, there is no need to secure a space for arranging the intermediate wheel or the like. Therefore, it is easy to achieve miniaturization and thinning.

Furthermore, since the calendar correction wheel 70 and the 24-hour correction wheel 80 can be directly meshed with the date wheel 50 and the 24-hour gear 42, the calendar correction wheel 70 and the 24-hour correction wheel 80 can be easily designed. In other words, since the calendar correction wheel 70 meshes only with the correction transmission wheel 90 and the date wheel 50, it is possible to have two meshing points and easily and freely design the tooth profile. Similarly, since the 24-hour correction wheel 80 is meshed only with the correction transmission wheel 90 and the 24-hour gear 42, two meshing points can be provided, and the tooth profile can be easily and freely designed. Therefore, the degree of freedom in designing the calendar correction wheel 70 and the 24-hour correction wheel 80 can be improved.

As described above, according to the display correction mechanism 13 of the present embodiment, it is possible to appropriately correct the display of the date wheel 50 and the 24-hour gear 42 (24-hour hour wheel 40) while reducing the number of parts. , miniaturization and thinning can be achieved.

Further, according to the information display mechanism 12, since the display correction mechanism 13 described above is provided, the display of the date wheel 50 and the 24-hour gear 42 (24-hour hour wheel 40) can be appropriately corrected as necessary. The date character 9 can be displayed appropriately, and the 24-hour hand 5 can be used to properly display the second time zone. Therefore, it is possible to appropriately display the date, time, etc. of two countries (cities) that differ due to, for example, the time difference.
Therefore, the movement 10 and timepiece 1 can be of high quality and high performance, and can be made smaller and thinner.

Furthermore, according to the present embodiment, by rotating the winding stem 15, the display of the date indicator 50 or the 24-hour gear 42 (24-hour hour wheel 40) can be arbitrarily selected and separately corrected. Easy to work with and easy to use.

Furthermore, since the rocking lever 60 is combined with the calendar correcting wheel 70, the calendar correcting wheel 70 can be moved as the rocking lever 60 rocks. Accordingly, the calendar correcting wheel 70 can be appropriately moved toward or away from the date dial 50 in response to the rocking motion of the rocking lever 60 . Therefore, when the rocking lever 60 is positioned at the first correction position P1, the calendar correction wheel 70 can be properly meshed with the internal teeth 51 of the date indicator 50. As shown in FIG. Therefore, it is easier to correct the display of the date indicator 50 more reliably.
Similarly, since the swing lever 60 is combined with the 24-hour correction wheel 80, the 24-hour correction wheel 80 can be moved as the swing lever 60 swings. Therefore, the 24-hour correction wheel 80 can be appropriately moved toward or away from the 24-hour gear 42 in response to the rocking motion of the rocking lever 60 . Therefore, the 24-hour correction wheel 80 can be appropriately meshed with the 24-hour gear 42 when the rocking lever 60 is positioned at the second correction position P2. Therefore, it is easier to correct the display of the 24-hour hand 5 more reliably.

Furthermore, since the rocking lever 60, the calendar correcting wheel 70 and the 24-hour correcting wheel 80 can be integrally assembled, the display correcting mechanism 13 can be assembled easily and efficiently.

When adjusting the time, the crown 14 is pulled out two steps to move the winding stem 15 from the 0th step to the 2nd step. As a result, for example, it is possible to link the date wheel via a not-shown handwheel or the like, and by rotating the winding stem 15, the minute hand 7, the hour hand 6, and the 24-hour hand 5 can be adjusted. Correction of the date wheel 50 can be performed.

As a result, the rocking lever 60 can push the calendar correction wheel 70 closer to the date indicator 50 when rocking toward the first correction position P1. Therefore, as shown in FIG. 18, the calendar correction wheel 70 can mesh with the internal teeth 51 of the date indicator 50 when the rocking lever 60 is moved to the first correction position P1.
At this time, the axle 71 of the calendar correcting wheel 70 is properly positioned by contacting the peripheral ends of the lower guide groove 131 and the upper guide groove 132, for example.

Furthermore, in this embodiment, since the calendar correction wheel 70 is arranged below the backing presser 16, as shown in FIG. are engaged. Therefore, power can be directly transmitted to the calendar correction wheel 70 through the first correction transmission wheel 91 and power can be directly transmitted to the 24-hour correction wheel 80 through the second correction transmission wheel 92 .

Even in the timepiece 1 of the present embodiment having the display correction mechanism 130 configured as described above, as shown in FIG. 18, when the swing lever 60 is moved to the first correction position P1, the calendar correction Since the wheel 70 can mesh with the internal teeth 51 of the date indicator 50, the display of the date indicator 50 can be appropriately corrected. Therefore, even in the case of this embodiment, it is possible to achieve the same effects as those of the first embodiment.

Note that, even in the case of this embodiment, the swing lever 60 can be positioned at the first correction position P1 and the second correction position P2.

As a result, the rocking lever 60 can be positioned at the first correction position P1, and further movement can be restricted.
Further, when the rocking lever 60 is moved to the second correction position P2, the second fixing pin 66 on the 24-hour correction wheel 80 side moves out of the peripheral end portion of the main guide groove 101, as in the first embodiment. It contacts the second peripheral end located on the 24-hour hour wheel 40 side. As a result, the rocking lever 60 can be positioned at the first correction position P2, and further movement can be restricted.

However, even in this case, the calendar correction wheel 70 can be properly meshed with the internal teeth 51 of the date dial 50 by swinging the swing lever 60 again to the first correction position P1.

(Modification of Second Embodiment)
In the above-described second embodiment, for example, as shown in FIGS. 20 and 21, an insertion hole 140 for inserting the axle 71 of the calendar correction wheel 70 may be formed in the rocking lever body 61 .
By doing so, the rocking lever 60, as shown in FIG. It can be pushed closer to the car 50 . Further, as shown in FIG. 21, when the rocking lever 60 rocks toward the second correction position P2, the inner edge of the insertion hole 140 is used to move the calendar correction wheel 70 away from the date indicator 50. can be pressed as

Accordingly, even when the rocking lever 60 is rocked toward either the first correction position P1 or the second correction position P2, the insertion hole 140 can be used to push the calendar correction wheel 70.

As a result, the rocking lever 60 can be positioned at the first correction position P1, and further movement can be restricted.
Further, when the rocking lever 60 moves to the second correction position P2, the axle 71 of the calendar correction wheel 70 moves to the second peripheral end of the lower guide groove 131 which is located on the 24-hour hour wheel 40 side. and the second peripheral end portion of the upper guide groove 132 located on the 24-hour hour wheel 40 side. It is sandwiched between the peripheral end portion and the inner edge portion of the insertion hole 140 . As a result, the rocking lever 60 can be positioned at the second correction position P2, and further movement can be restricted.

Although embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. Embodiments can be implemented in various other forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. Embodiments and modifications thereof include, for example, those that can be easily imagined by those skilled in the art, those that are substantially the same, and those within an equivalent range.

For example, in each of the above-described embodiments, a mechanical timepiece has been described as an example, but the present invention is not limited to this case, and may be applied to, for example, a quartz timepiece. In this case, for example, the driving force of the step motor may be used to rotate each wheel.

Furthermore, in each of the above embodiments, the date wheel is used as the first display wheel for displaying the first information, and the 24-hour hour wheel with the 24-hour hand is used as the second display wheel for displaying the second information. is not limited to the case of For example, a day wheel that displays the day of the week may be applied as the first display wheel, and various display wheels that display other information may be applied as the first display wheel and the second display wheel.

Furthermore, in each of the above-described embodiments, the swing lever is attached so as to clip (clip) the connecting shaft constituting the correction transmission wheel between the swing lever main body and the tip of the lever spring. Although the case where the lever and the correction transmission wheel are combined with a predetermined rotational resistance has been described as an example, the present invention is not limited to this case.
For example, by clipping the rocking lever to the calendar correcting wheel and clipping the rocking lever to the 24-hour correcting wheel, the rocking lever, the calendar correcting wheel and the 24-hour correcting wheel may be combined in a state of having a predetermined rotational resistance. Even in this case, the rocking lever can be rocked about the rocking axis with the rotation of the correction transmission wheel as long as the rocking lever does not receive resistance exceeding the rotational resistance. When received, the calendar correction wheel and the 24-hour correction wheel can be rotated with the rotation of the correction transmission wheel while the position of the rocking lever remains as it is.
Therefore, even in this case, the same action and effect can be achieved.
