Description

The present invention relates to a time setting device for a mechanical watch, a mechanical watch, and a time setting system for a mechanical watch.

Mechanical watches do not have any internal electronic parts such as motors, so they do not have the ability to correct errors on their own like radio-controlled watches, and the time must be set manually by the user. I have no choice but to do it.

However, to manually correct errors in a mechanical watch, the hands must be corrected while referring to the accurate current time, which is cumbersome.

Therefore, an external correction device has been proposed that automatically corrects the hands of a mechanical watch when the mechanical watch is placed (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2016-090507

The external correction device described in Patent Document 1 takes a photograph of the hands of a mechanical watch that has been set, and analyzes the image of the photograph to determine the time that the mechanical watch is displaying (at the time of display). The pointer is driven to correct the displayed time to the current time, which is the actual time acquired by the current time acquisition section.

However, since this external correction device analyzes images taken of the dial and hands, it is necessary to make the dial and hands relatively simple in shape to improve the accuracy of image recognition. Therefore, it is difficult to add elaborate decorations to the dial and hands, making it difficult to improve the design of mechanical watches.

<Configuration of mechanical watch>
The mechanical timepiece 100 of the present embodiment is an example of a mechanical timepiece according to the present invention, and is also an example of a mechanical timepiece constituting a time adjustment system 300, which is an example of a time adjustment system for a mechanical timepiece according to the invention. There is also.

The mechanical timepiece 100 is a purely mechanical timepiece that does not include any electronic parts, including batteries, and is comprised only of mechanical structural elements. The mechanical watch 100 is, for example, a wristwatch. As shown in FIG. 3, the mechanical watch 100 has a cylindrical case 110 (including the bezel) made of a metal material such as stainless steel or titanium, whose front side is covered with a windshield 120 and whose back side is closed. It is covered by a back cover 130.

The windshield 120 is formed in the shape of a transparent disk, and allows the dial 140 and the hands 151, 152 that indicate the time, which are provided inside the mechanical watch 100, to be visible from the outside of the mechanical watch 100 through the windshield 120. Can be done.

Note that a hole 141 is opened in the half of the dial 140 near the crown 157, which will be described later, and a movement placed on the back side of the dial 140 can be inserted from the outside of the windshield 120 through the hole 141. 150 and a balance wheel 153 can be visually recognized.

The back cover 130 is formed of an annular frame 131 made of metal and a disc-shaped transparent glass plate 132 provided inside the frame 131. Therefore, from the outside of the back cover 130 side, through the glass plate 132, inside the mechanical watch 100, the movement 150 provided on the back side of the dial 140, and the rotating movement provided on the side closer to the back cover 130 than the movement 150. The weight 154 and the like can be visually recognized.

The movement 150 also has a through hole 155 that penetrates from the front side (windshield 120 side) to the back side (back cover 130 side), and the balance 153 is disposed in this through hole 155. Therefore, the balance 153 of the movement 150 can be visually recognized from the outside of the back cover 130 through the glass plate 132.

The hands 151 and 152 display the time by pointing to numbers or indexes corresponding to the time, which are formed at predetermined positions on the front surface of the dial 140, respectively, while rotating. The hands 151 and 152 are, for example, an hour hand representing the hour of the time and a minute hand representing the minutes of the time. The back surface 140b of the dial 140 is painted, for example, black so as to suppress reflection of light.

The movement 150 is provided with a crown 157 that is connected to hands 151 and 152 via an interlocking mechanism (not shown). The crown 157 is an example of an operating member configured to allow the hands 151, 152 to be moved from the outside. The crown 157 is arranged outside the case 110, and by rotating it, the hands 151, 152 can be rotated.

A detection hole 156 that penetrates from the front side to the back side is formed in the half side of the movement 150 opposite to the half side where the balance 153 is arranged (the half side far from the crown 157). ing.

The front side of the detection hole 156 faces the back surface 140b of the dial 140, and the back side faces the back cover 130. A jumper 160 is arranged on the front side of the movement 150, as shown in FIGS. 3 and 4.

The jumper 160 is formed at the tip of a flexible portion 163 extending in an arc shape from a gear train presser 162 fixed to the front side of the movement 150. The jumper 160 is integrally formed with a gear train presser 162 and a flexible portion 163. The train wheel presser 162, the flexible portion 163, and the jumper 160 are made of the same metal. As shown in FIG. 5, the flexible portion 163 can be bent in the radial direction of the movement 150, with one end connected to the gear train presser 162 serving as a fixed end, and the other end where the jumper 160 is formed being a free end.

A jumper drive wheel 158 is arranged near (on the back side) of the jumper 160 of the movement 150. The jumper drive wheel 158 rotates in conjunction with an hour wheel (which rotates once every 12 hours) to which the pointer 151 (for example, the hour hand) is fixed at a rotation speed that is 1/2 of the rotation speed of the hour wheel.
Since the hour wheel rotates once every 12 hours, the jumper drive wheel 158 rotates once every 24 hours in the clockwise direction.

The jumper drive wheel 158 is formed with a boss 158a that protrudes in a direction parallel to the rotation axis of the jumper drive wheel 158. The boss 158a contacts the side surface 161 of the jumper 160 within a predetermined rotation angle range of the jumper drive wheel 158 as the jumper drive wheel 158 rotates.

As the jumper drive wheel 158 further rotates, the boss 158a pushes the side surface 161 of the jumper 160 radially outward, thereby moving the jumper 360 radially outward. As a result, the bending portion 363 is bent so that the radius of curvature of the bending portion 163 becomes larger, as shown by the solid line in FIG. 5 .

When the jumper drive wheel 158 rotates to a position where the boss 158a passes the innermost edge of the side surface 161 of the jumper 160, the boss 158a separates from the jumper 160, and the load that was pressing the jumper 160 radially outward disappears. .

As a result, the jumper 160, which had been displaced to the outermost position shown by the two-dot chain line in FIG. (for example, within 1 second) is returned to the original position (inward position in the radial direction) shown by the solid line.

Here, the trajectory of the jumper 160 that is displaced from the original position (the position shown in FIG. 4) where the boss 158a is not in contact with the outermost position shown in FIG. It is arranged to cover gradually.

When the jumper 160 is in the original position shown in FIG. 4, the flexible portion 163 is not bent and covers only a part of the detection hole 156, and is in the outermost position shown by the solid line in FIG. At some point, the bending portion 163 is most bent, and substantially the entire detection hole 156 is covered.

A reflective plate is provided on the back surface 160b of the jumper 160. Therefore, for example, when the light L1 is incident on the detection hole 156 from the back cover 130 side to the front side as shown in FIG. At this time, almost all of the incident light reaches the back surface 140b of the dial 140, which is painted black. The light incident on the back surface 140b is absorbed by the back surface 140b, and reflection is suppressed, so that almost no reflected light L2 returns to the back cover 130 side.

On the other hand, when the jumper 160 is at the outermost position, almost all of the incident light is reflected by the reflection plate provided on the back surface 160b of the jumper 160, and a large amount of reflected light L2 is directed toward the back cover 130 side. returns.

As described above, the jumper drive wheel 158 rotates once every 24 hours in conjunction with the movement of the hour wheel, so the position of the boss 158a corresponds to the position of the pointer 151 in a specific time range. For example, when the pointer 151 is at a position corresponding to the time around 21:00, the boss 158a begins to touch the jumper 160, and when the pointer 151 is at the reference position corresponding to the time 0:00:00, the boss 158a is moved away from the jumper 160. is set to .

In other words, the jumper 160 starts moving radially outward from around 21:00, returns to its original position from its outermost position at 0:00:00, and remains in its original position until the next time around 21:00. It is maintained and does not move.

Therefore, the jumper 160 moves from the outermost position to the original position in response to the pointer 151 at time 0:00:00, and at this time, the light L1 incident on the detection hole 156 hits the back surface of the jumper 160. The reflected light L2 reflected by the reflection plate suddenly decreases from the maximum light intensity.

As a result, the optical characteristics of the jumper 160 change with respect to the light L1 incident on the detection hole 156 in accordance with the reference position of the pointer 151. Therefore, the jumper 160 is an example of an optical characteristic changing unit that is set so that a change in the optical characteristic, that is, a change in the amount of reflected light L2, can be detected from the outside through the back cover 130.

The rotating weight 154 is for winding up a mainspring that is a power source of the mechanical timepiece 100, and rotates around a rotating shaft provided at the center of the movement 150, for example. Note that the jumper 160 faces the outside through the detection hole 156 in the rotation range H of the rotary weight 154.

In the mechanical clock 100, the jumper drive wheel 158 does not rotate in a 24-hour cycle but rotates in a 12-hour cycle when there is no need to distinguish between morning and afternoon when the time is displayed using the hands 151 and 152. You can also use it as In this case, the jumper drive wheel 158 may rotate at the same angular velocity as the hour wheel.

<Configuration of time adjustment device>
The time setting device 200 of this embodiment is an example of a time setting device according to the present invention, and is also an example of a time setting device constituting a time setting system 300, which is an example of a time setting system for a mechanical watch according to the present invention. There is also.

The time setting device 200 shown in FIGS. 1 to 3 is formed separately from the mechanical watch 100, and is used when setting the time of the mechanical watch 100. The time setting device 200 includes a clock placement section 220, a hand position detection section 230, a time clock section 240, a hand drive section 250, and a control section 260.

The watch placement unit 220 positions and places the mechanical watch 100 at a predetermined position on the stand 210, which is the exterior of the time setting device 200. Specifically, as shown in FIG. 3, the timepiece placement portion 220 is in contact with the outer periphery of the frame 131 of the mechanical timepiece 100, and the mechanical timepiece 100 is placed on a horizontal plane with the crown 157 facing downward and the movement 150. Hold it in a tilted position.

Since the mechanical watch 100 is tilted with respect to the horizontal plane when placed in the watch placement section 220, the rotating weight 154 is tilted due to its own weight in the lower half of the movement 150, that is, the half near the crown 157. located on the side of

The pointer drive section 250 includes a drive section 251 and a connecting shaft 252. The drive unit 251 includes a motor and a reduction gear train. The connecting shaft 252 is fitted and connected to the crown 157 of the mechanical watch 100 placed in the watch placement part 220, and transmits the rotation of the driving part 251 to the crown 157, and rotates the crown 157. , drives the hands 151 and 152 connected to the crown 157.

The hand position detection section 230 is provided at a position facing the detection hole 156 through the back cover 130 of the mechanical timepiece 100 placed in a predetermined attitude in the timepiece placement section 220. The pointer position detection section 230 is a reflective type equipped with a light emitting section 231 such as an LED that emits light L1 toward the detection hole 156, and a light receiving section 232 that receives reflected light L2 from the jumper 160 through the detection hole 156. It is a photo reflector.

This pointer position detection section 230 is mounted on a circuit board 233 together with various electronic components. In order to protect the pointer position detecting section 230, a protective plate 211 having a translucent property that transmits the light L1 and the reflected light L2 is provided on the outer surface of the stand 210 on which the pointer position detecting section 230 is arranged. .

The hand position detection unit 230 detects the reference position of the hands 151 and 152 corresponding to 0:00:00 by detecting a change in the amount of reflected light L2 from the jumper 160 that has passed through the detection hole 156.

The time measuring unit 240 accurately measures the current time by receiving, for example, a radio wave containing information indicating time, which is received by a so-called radio-controlled timepiece.

The control unit 260 determines the position of the hands 151, 152 corresponding to the current time measured by the time clock unit 240 based on the reference position of the hands 151, 152 corresponding to 0:00:00 detected by the hand position detecting unit 230. The pointer driving unit 250 is controlled to drive the hands 151, 152 of the mechanical timepiece 100 until the point where the hands 151, 152 of the mechanical timepiece 100 are driven.

Note that the control unit 260 stores the correspondence between the drive amount of the drive unit 251 and the drive amount (rotation angle) of the hands 151 and 152, and stores the correspondence relationship between the drive amount of the drive unit 251 and the drive amount (rotation angle) of the hands 151 and 152, and stores the correspondence relationship between the drive amount of the drive unit 251 and the drive amount (rotation angle) of the hands 151 and 152. The drive amount of the drive unit 251 is calculated based on the correspondence, and the drive unit 251 is controlled.

<Operation of the time adjustment system of mechanical watches>
The time adjustment system 300 configured as described above operates as follows.

First, the mechanical watch 100 is placed in a predetermined posture on the watch placement section 220 of the time setting device 200 by a user. At this time, the mechanical watch 100 is arranged with the crown 157 at the lowest position, the detection hole 156 of the mechanical watch 100 faces the pointer position detection section 230, and the crown 157 is connected to the connecting shaft 252. The state will be as follows.

When the mechanical timepiece 100 is placed in the timepiece placement section 220 in a predetermined posture, the rotary weight 154 is stopped at the lowest position near the crown 157 due to its own weight. The side opposite to the crown 157 is located on the upper side, and the rotating weight 154 is not located between the pointer position detection section 230 and the detection hole 156 formed on the upper side. As a result, the detection hole 156 is not blocked by the rotating weight 154, so that detection of the positions of the hands 151 and 152 by the pointer position detection section 230 is not hindered.

When the user presses a time setting start button (not shown) provided on the stand 210 of the time setting device 200, the control unit 260 adjusts the hands 151, 152 of the mechanical watch to 0:00:00. The pointer driving section 250 is controlled so as to drive the pointer in fast forward motion to a position corresponding to seconds.

Note that instead of the user manually pressing the start button, the time setting device 200 detects that the mechanical watch 100 is placed in the watch placement section 220, and based on this detection result, the above-mentioned control is performed. Control by section 260 may be started automatically.

Detection that the mechanical timepiece 100 is placed in the timepiece placement section 220 can be done, for example, by detecting a change in the amount of light received by the light receiving section 232 of the pointer position detection section 230 (when the mechanical timepiece 100 is not placed). This can be done by detecting a change in the amount of light received when the amount of received ambient light changes due to the placement of the mechanical watch 100.

The control unit 260 drives the drive unit 251, rotates the connecting shaft 252 connected to the driving unit 251, rotates the crown 157 connected to the connecting shaft 252, and sets the hands 151, 152 to the normal time. Rotate at a faster speed than rotation for display.

While the pointers 151 and 152 are being rotated in fast forward motion, the light emitting section 231 of the pointer position detection section 230 emits light L1 toward the detection hole 156, and the light receiving section 232 continues to receive reflected light L2 from the jumper 160. , waits to detect the moment when the amount of the received reflected light L2 instantly decreases.

As described above, the moment when the amount of reflected light L2 received from the jumper 160 instantly decreases is the moment when the jumper 160 returns from its outermost position to its original position, and the positions of the pointers 151 and 152 are 0. This is the moment when the reference position corresponding to hour 00 minute 00 seconds is reached.

The pointer position detecting section 230 detects the reference position of the pointer corresponding to 0:00:00 by detecting the moment when the light intensity of the received reflected light L2 instantly changes to a small value, and the pointer position detecting section 230 detects the reference position of the pointer corresponding to 0:00:00. At the moment of this detection, it is detected that the hands 151, 152 of the mechanical timepiece 100 are at the reference position corresponding to the time 0:00:00, and the control unit 260 recognizes the reference position of the hands 151, 152.

The control unit 260 controls the mechanical clock so that the hands 151 and 152 indicating the reference position corresponding to 0:00:00 are at the position corresponding to the current time measured by the time clock unit 240. The pointer drive section 250 is controlled to drive the 100 pointers 151 and 152 in fast forward motion.

When the hands 151 and 152 are driven to the position corresponding to the current time, the control unit 260 controls the driving of the hand drive unit 250 to stop, and also ends the operation of the hand position detection unit 230 (stops emitting light). The light receiving section 231 stops emitting light, and the light receiving section 232 stops receiving light and detecting the amount of received light.

As described above, according to the time setting system 300 of the mechanical watch 100 of this embodiment, there is no need to analyze the images of the dial 140 and the hands 151, 152. Therefore, the time setting system 300 of the mechanical watch 100 of this embodiment accurately sets the time of the mechanical watch 100 without depending on the shape of the dial 140 or the hands 151, 152 of the mechanical watch 100. be able to

FIG. 7 is a perspective view showing the jumper 160 in which the deflection of the flexible portion 163 is restricted by a deflection regulating portion.

The mechanical watch 100 in the time setting system 300 of this embodiment detects the timing of a change in optical characteristics (a change in which the amount of reflected light suddenly decreases) based on a change in the movement of the jumper 160. There is a possibility that variations may occur due to slight fluctuations in the deflection of the flexible portion 163.

Therefore, in order to reduce variations in the deflection of the flexible portion 163, as shown in FIG. 7, a deflection regulating portion that regulates the direction in which the flexible portion 163 is deflected may be provided. Here, the deflection regulating section includes, for example, a groove section 164 formed in a section of the deflecting section 163 near the jumper 160 and extending radially outward of the movement 150 in which the jumper 160 is displaced, and a movement inserted into the groove section 164. 150 and a pin 159 fixed to the pin 150.

According to the deflection regulating section configured in this way, when the jumper 160 is displaced radially outward, the groove 164 is displaced radially outward while being regulated by the pin 159, and the jumper 160 is returned to its original position. When returning to , the groove portion 164 is also displaced inward in the radial direction while being regulated by the pin 159 . Thereby, variations in the deflection of the flexible portion 163 can be reduced.

FIG. 8 is a schematic diagram showing a mechanical timepiece 100 in which a detection hole 156 is formed in a rotation range H of a rotary weight 154.

As shown in FIG. 8, the mechanical timepiece 100 in the time setting system 300 of this embodiment has a detection hole 156 formed in the rotation range H of the rotary weight 154. Since the mechanical watch 100 is arranged with the half side where the detection hole 156 is formed as the upper side and the half side where the detection hole 156 is not formed as the bottom side, the rotary weight 154 is aligned with the detection hole 156. This prevents the pointer position detection section 230 from being placed between the pointer position detection section 230 and the pointer position detection section 230.

However, the time adjustment system 300 in this embodiment is not limited to this form. That is, for example, the timepiece arrangement section 220 of the time setting device 200 may arrange the mechanical timepiece 100 in such a manner that the half side where the detection hole 156 is formed faces downward.

FIG. 9 shows a mechanical timepiece 100 in which an opening 154c such as a small window or notch is formed at the intersection of a straight line connecting the detection hole 156 of the rotary weight 154 and the pointer position detection section 230. It is a schematic diagram equivalent to FIG. 8.

With this configuration, the rotary weight 154 stopped at the lower side due to its own weight can be placed between the detection hole 156 and the pointer position detection section 230. In this case, as shown in FIG. 9, the mechanical watch 100 may be equipped with a small window, cutout, etc. What is necessary is to form an opening 154c. This can prevent the pointer position detection section 230 from being obstructed in detecting optical changes through the detection hole 156.

FIG. 10 is a schematic diagram corresponding to FIG. 8 showing a mechanical timepiece 100 in which the detection hole 156 is formed outside the rotation range H of the rotating weight 154 in the radial direction.

Further, as shown in FIG. 10, the mechanical timepiece 100 may be one in which the detection hole 156 is formed radially outside the rotation range H of the rotating weight 154 (or the detection hole 156 is formed outside the rotation range H of the rotating weight 154). may be formed so that it is radially inner than the detection hole 156 (having a smaller radius).

In this case, even if the rotary weight 154 is stopped at any angular position within the rotation range H, the rotary weight 154 will not be disposed between the detection hole 156 and the pointer position detection section 230. Therefore, the detection hole 156 may be formed in the lower half where the rotary weight 154 stops, as shown in FIG. This can prevent the detection of optical changes through the light from being obstructed.

FIG. 11 shows a mechanical timepiece 100 corresponding to FIG. 3, in which a cylindrical light shielding tube 171 is provided between a movement 150 and a glass plate 132 corresponding to the range where the detection hole 156 is extended to the glass plate 132. FIG.

In addition, in the mechanical watch 100 in which the detection hole 156 is formed outside the rotation range H of the rotating weight 154 in the radial direction, as shown in FIG. It is preferable to provide a cylindrical light shielding tube 171 between the movement 150 and the glass plate 132.

According to the mechanical watch 100 configured in this way, the light shielding tube 171 that does not interfere with the rotating oscillating weight 154 prevents the light L1 and the reflected light that go back and forth between the pointer position detection section 230 and the detection hole 156. For example, external light L3 that has reached the back side of the movement 150 through the hole 141 of the dial 140 and the through hole 155 of the movement 150 is prevented from entering the optical path of L2. Thereby, the pointer position detection section 230 can eliminate the influence of the external light L3 and accurately detect a change in the amount of reflected light L2.

Note that in place of the light shielding tube 171 or in combination with the light shielding tube 171, an optical fiber 172 may be provided between the detection hole 156 and the glass plate 132 to completely reflect the light inside and guide the light. Thereby, the light L1 and reflected light L2 that go back and forth between the pointer position detection section 230 and the detection hole 156 can be prevented or suppressed from being scattered to the outside.

FIG. 12 is a cross-sectional view, corresponding to FIG. 3, showing a mechanical watch 100 that is provided with a light-shielding tube 171 and an optical fiber 172 and whose mainspring is manually wound.

The provision of the light shielding tube 171 and the optical fiber 172 between the movement 150 and the glass plate 132 is limited to the mechanical watch 100 in which the detection hole 156 is formed outside the rotation range H of the rotary weight 154 in the radial direction. It is not something that will be done. That is, as shown in FIG. 12, even in a so-called mechanical watch 100 that does not include a rotating weight 154 and whose mainspring is wound manually, the rotating weight 154 does not interfere, so a light-shielding tube 171 and an optical fiber 172 are provided. Can be done.

For example, as shown in FIG. 3, in an embodiment in which the detection hole 156 is arranged in the rotation range H because the rotation range H of the rotary weight 154 is large, it is not necessary to provide the light-shielding tube 171 or the optical fiber 172. Can not.

However, due to the configuration in which the hole 141 of the dial 140 and the through hole 155 of the movement 150 are located in the rotation range H, when the mechanical watch 100 is positioned in the watch placement section 220, the rotating weight 154 placed below is in a state where the through hole 155 is covered.

Therefore, by painting the front surface 154a of the rotary weight 154 black, etc., and absorbing the external light L3 incident through the through hole 155 on the front surface 154a, the pointer position detection section 230 and the detection hole 156 can be connected. It is possible to prevent the external light L3 from entering the optical path of the light L1 and the reflected light L2 that go back and forth between the two.

In the mechanical watch 100 used in the time setting system 300 of the embodiment described above, the detection hole 156 penetrates the movement 150, and when the jumper 160 is in the original position, the light emitting part 231 of the pointer position detection part 230 The light L1 emitted from the dial 140 is absorbed by the black back surface 140b of the dial 140, and is configured so as to hardly be reflected.

FIG. 13 is a sectional view corresponding to FIG. 3, showing a mechanical timepiece 100 having a structure in which the detection hole 156 does not penetrate the movement 150.

However, the mechanical timepiece 100 is not limited to this form, and the detection hole 156 may not penetrate the movement 150, as shown in FIG. 13. In this case, the surface 150b serving as the bottom of the detection hole 156 (abutting surface) may be formed so as not to reflect the light L1.

In the mechanical watch 100 configured in this manner, the bottom surface 150b of the detection hole 156 has the same effect as the back surface 140b of the dial 140 in the mechanical watch 100 shown in FIG. It can be a mechanical watch used in the setting system 300.

In the mechanical watch 100 used in the time setting system 300 of the embodiment described above, the back surface 160b of the jumper 160 has a reflective plate, and the light receiving unit 232 detects the reflected light L2 reflected by the jumper 160. However, the time adjustment system according to the present invention is not limited to this form.

FIG. 14 is a sectional view corresponding to FIG. 3, showing a mechanical timepiece 100 having a configuration in which a reflector 143 is provided on the back surface 140b of the dial 140 and the back surface 160b of the jumper 160 absorbs the light L1.

That is, as shown in FIG. 14, the mechanical watch 100 used in the time setting system 300 of the embodiment described above includes a reflective plate 143 on the back surface 140b of the dial 140, and the back surface 160b of the jumper 160 reflects the light L1. It may also be configured to absorb.

In this time setting system 300, the pointer position detection section 230 of the time setting device 200 detects the minimum amount of reflected light L2 when the jumper 160 is located at the outermost position, and corresponds to the reference position of the hands 151, 152. When the jumper 160 returns to its original position, the maximum amount of reflected light L2 is detected.

Therefore, the hand position detection unit 230 can detect that the hands 151 and 152 are at the reference position at the timing when the amount of detected reflected light L2 switches from the minimum to the maximum.

In the time setting system 300 of the embodiment described above, the pointer position detection section 230 has a light emitting section 231 and emits light L1 from the light emitting section 231 toward the detection hole 156. The position detection section 230 may be configured without the light emitting section 231.

In FIG. 15, a hole 144 for guiding external light L4 to the detection hole 156 is formed in the dial plate 140 corresponding to the detection hole 156, and the light is guided from the outside to the detection hole 156 through the hole 144 of the dial plate 140. 4 is a sectional view corresponding to FIG. 3 and showing a mechanical timepiece 100 configured to block external light L4 with a jumper 160. FIG.

In this case, for example, as shown in FIG. 15, a hole 144 for guiding external light L4 to the detection hole 156 is formed in the dial plate 140 corresponding to the detection hole 156, so that the dial plate can be accessed from the outside of the mechanical watch 100. The configuration may be such that the external light L4 guided to the detection hole 156 through the hole 144 of 140 is blocked by the jumper 160.

In this time setting system 300, the pointer position detection section 230 (light receiving section 232) of the time setting device 200 detects the minimum amount of external light L4 when the jumper 160 is located at the outermost position, and When the jumper 160 returns to its original position corresponding to the reference position, the maximum amount of external light L4 is detected.

Therefore, the pointer position detection unit 230 can detect that the pointers 151 and 152 are at the reference position at the timing when the amount of detected external light L4 switches from the minimum to the maximum.

In FIG. 16 , the light emitting unit 231 and the light receiving unit 232 are not adjacent to each other but are separated from each other, and the detection hole 156 provides an optical path for the light L1 emitted from the light emitting unit 231 and a path for the reflected light L2 reflected by the jumper 160 to reach the light receiving unit 232. 4 is a sectional view corresponding to FIG. 3, showing a mechanical timepiece 100 having a configuration divided into a forward optical path and a forward optical path.

The time setting system 300 of the embodiment described above has a configuration in which the light emitting section 231 and the light receiving section 232 of the pointer position detecting section 230 are adjacent to each other and are arranged as an integrated photoreflector. In the type watch 100, the light emitting part 231 and the light receiving part 232 are not adjacent to each other but are separated from each other, and the detection hole 156 is arranged so that the light L1 emitted from the light emitting part 231 passes through the optical path and the reflected light L2 reflected by the jumper 160 passes through the light receiving part 232. The configuration may be such that the optical path is divided into two.

The time adjustment system 300 configured in this manner can also provide the same effects as the time adjustment systems of the respective embodiments described above.

FIG. 18 is a diagram showing a date plate (date wheel) 180 that is used as an optical characteristic changing unit in place of the jumper 160 and rotates only once a day during a predetermined time period.

The time setting system 300 of this embodiment uses the jumper 160 of the mechanical watch 100 as an optical characteristic changing section that changes the optical characteristics. As shown, a date plate (date dial) 180 that rotates only once a day during a predetermined time period may be applied as the optical characteristic changing section.

That is, for example, a pattern whose optical characteristics change is formed on the back surface 180b of the date plate 180. Specifically, as shown in FIG. 18, each angular range J of the date plate 180 that rotates in one day is divided into a range J1 of the non-reflective part 181 painted in black and a reflective part 182 painted in white. range J2. The non-reflecting portion 181 absorbs the light L1 without reflecting it, and the reflecting portion 182 reflects the light L1 and emits reflected light L2.

Before the time 0:00:00 corresponding to the reference position of the hands 151, 152, the non-reflective portion 181 of the date plate 180 faces the detection hole 156, and the time 0:00 is displayed. At 00 seconds, the reflecting section 182 switches to a state facing the detection hole 156.

Thereby, the mechanical timepiece 100 can be provided with the date plate 180 as an optical characteristic changing section in place of the jumper 160.

FIG. 19 is a diagram showing a gear 190 used as an optical characteristic changing section instead of the jumper 160.

Similarly, instead of the jumper 160, a gear 190 with a hole 191 shown in FIG. 19 can be used as the optical characteristic changing section. This gear 190, like the jumper drive wheel 158 shown in FIG. 4, rotates once every 24 hours. By configuring the hole 191 to face the detection hole 156 at time 0:00:00, the pointer position detection section 230 detects the reference positions of the hands 151, 152 based on changes in the reflected light L2. be able to.

The optical property changing unit in the present invention is not limited to one that changes the optical property in a 24-hour period, but for example, the optical property changing unit may change the optical property for one hour, for example, so that the resolution for changing the optical property can be made higher. By adding a part that operates to change the optical properties periodically (operates once every hour), and combining multiple parts that change the optical properties at different cycles, the optical properties can be improved. The accuracy of the change may be increased.

Further, the optical property changing section in the present invention is not limited to the above-mentioned light amount, reflectance, and transmittance of the reflected light L2, but also includes the phase, optical path length, polarization direction, wavelength, color tone, refraction, direction or focus of the light beam, etc. One or a combination of two or more may be changed.

Further, the mechanical timepiece or time setting device according to the present invention may be provided with a lens, a prism, a mirror, a wavelength plate, a polarizing plate, a color filter, an optical waveguide, or the like as an optical element.

Further, in order to reduce stray light inside the mechanical watch or the time setting device, the inside of the mechanical watch or the time setting device may be painted black to absorb light.

The time setting system 300 of the present embodiment is configured such that the reference positions of the hands 151 and 152 that cause an instantaneous change in the amount of reflected light L2 caused by the jumper 160 of the mechanical watch 100 are set at a timing corresponding to the time 0:00:00. However, the reference position of the pointers 151 and 152 at which the jumper 160 causes an instantaneous change in the amount of reflected light L2 is not limited to the timing corresponding to 0:00:00, but may be any other position. The timing may correspond to the time of day.

The time adjustment system 300 and time adjustment device 200 of the embodiments described above adjust the positions of the hands 151, 152 only using the reference positions of the hands 151, 152 corresponding to a specific time (for example, time 0:00:00). However, the time setting system and time setting device according to the present invention may detect the position of the hands 151, 152 of the mechanical watch 100 corresponding to an arbitrary time.

The mechanical watch 100 of this embodiment is configured so that the balance 153, which is the most characteristic feature of the mechanical watch 100, is visible. The balance 153 is not limited to being visible from the outside, and the balance 153 may not be visible from the outside.

FIG. 20 shows a watch holder 220 that can be detachably attached to a timepiece placement section 220 for positioning and arranging two types of mechanical watches 100' and 100'' with different external shapes, respectively. It is a schematic diagram showing two types of adapters 221 and 222 provided.

As shown in FIG. 20, the time setting device 200 of the present embodiment has a clock placement section 220 that is configured to accommodate multiple types of mechanical watches with different external shapes (for example, a mechanical watch 100' with a diameter D1 and a mechanical watch 100' with a diameter D2 (<D1)). A plurality of types of adapters 221 and 222 are removably provided in the timepiece placement section 220 and respectively position the plurality of types of mechanical watches 100' and 100'' at predetermined positions, respectively, corresponding to the mechanical watches 100''). It may also have the following.

According to this time setting device 200, one of the adapter 221 corresponding to the mechanical watch 100' having a diameter D1 and the other adapter 222 corresponding to the mechanical watch 100'' having a diameter D2 is selectively connected to the watch arrangement portion 220. By simply adding the two types of mechanical watches 100', 100'' with different external shapes to one time setting device 200, it is possible to selectively install two types of mechanical watches 100', 100'' with different external shapes. Compared to the case where a dedicated time setting device 200 is prepared for each ", the cost can be reduced.

Note that the time setting device 200 shown in FIG. 20 is a mechanical watch with a different external shape from the two types of mechanical watches 100' and 100'' by not adding any adapters 221 and 222 to the timepiece placement part 220. The watch 100 can be placed in the watch placement section 220.

Further, the time setting device according to the present invention is not only compatible with a plurality of types of mechanical watches with different external shapes as described above, but also with a plurality of types of mechanical watches with optical characteristic changing parts provided at different positions. In order to be compatible with watches, a plurality of hand position detection sections corresponding to the positions of the optical characteristic changing sections may be provided.

The time setting system 300 of this embodiment drives the hands 151, 152 to set the time with the mechanical watch 100 placed in the time setting device 200. The crown 157 may be driven to wind the winding. In this case, the mechanical timepiece 100 may be configured to switch between driving the hands 151 and 152 and winding the mainspring depending on the direction of rotation of the crown 157.

Note that in the time setting system 300 of this embodiment, when the user presses the button to start time setting with the mechanical watch 100 placed in the time setting device 200, the hands 151, 152 of the mechanical watch 100 However, if the mechanical watch 100 continues to be placed in the time setting device 200 after setting the time, even if the button to start time setting is not pressed afterwards. The time adjustment operation may be performed again at predetermined time intervals, or the time adjustment operation may be performed again at a specific time.

Further, in the time setting system 300 of the present embodiment, after the time setting is performed by driving the hands 151, 152 of the mechanical watch 100 with the mechanical watch 100 placed in the time setting device 200, the mechanical watch 100 continues to be placed in the time setting device 200, the mechanical watch 100 is not operated using the mainspring of the mechanical watch 100 as power, but the time clock unit 240 of the time setting device 200 keeps time. The control section 260 may control the pointer drive section 250 so that the points 151 and 152 are always aligned at the current time.

In this case, the mechanical timepiece 100 continues to be time-adjusted by the time-setting device 200 while it is placed in the time-setting device 200, so that the accuracy of the electronic timepiece is maintained. Therefore, the moment the mechanical watch 100 is removed from the time setting device 200, the time can always be accurately set.

The mechanical watch 100 in the embodiment described above is set so that the amount of reflected light L2 changes instantaneously at a predetermined timing of 0:00:00, but in the actual mechanical watch 100, Individual differences may occur due to manufacturing errors within the design tolerance range of the component parts and integration errors when the component parts are combined.

In other words, in the manufactured mechanical watch 100, even if the hands 151, 152 point to 0:00:00 at the time 0:00:00, the amount of reflected light L2 changes instantaneously due to individual differences. It happens that the time to do so is 0:00:02 or 23:29:51.

Even though the mechanical watches 100 have such individual differences, if the time setting device 200 sets the time of each mechanical watch 100 without considering the individual differences, only the individual differences between the mechanical watches 100 will occur. , the positions of the hands 151 and 152 will deviate from the time.

Therefore, individual differences at the time of manufacture are recorded in each mechanical watch 100, and when the time setting device 200 sets the time of the mechanical watch 100, the time setting device 200 The time adjustment device 200 may read the recorded individual differences and drive the hands 151 and 152 so as to point to a time offset by an amount corresponding to the read individual differences.

Note that since the mechanical timepiece 100 does not include any electronic parts, a semiconductor memory or the like cannot be used as a record of the individual differences described above.

Therefore, information is recorded non-electronically on the case back 130 and case 110 of the mechanical watch 100, such as a sticker expressing the individual differences corresponding to the mechanical watch 100 using codes such as one-dimensional barcodes and two-dimensional barcodes. Individual differences can be recorded by pasting them.

In this case, the time setting device 200 includes a reading unit that reads codes represented by one-dimensional barcodes, two-dimensional barcodes, etc., and the control unit 260 detects individual differences corresponding to the codes read by the reading unit. The amount of drive of the hands 151 and 152 by the hand drive unit 250 may be offset by the amount corresponding to the acquired individual difference.

Note that, since the mechanical watch 100 does not include electronic parts in the watch body including the movement 150, an RFID tag or the like that electronically records individual differences may be built into the watch band instead of the watch body.

In this case, the time setting device 200 includes a reading unit that wirelessly reads the individual difference information stored in the RFID tag, and the control unit 260 controls the individual difference information based on the individual difference information read by the reading unit. , and offset the amount of drive of the pointers 151 and 152 by the pointer driving section 250 by an amount corresponding to the obtained individual difference.

Note that if the time setting system 300 of the mechanical watch 100 is a set in which the mechanical watch 100 and the time setting device 200 are associated with each other on a one-to-one basis, the control unit 260 of the time setting device 200 has the corresponding mechanical The individual differences of the mechanical watches 100 are recorded in advance, and when the control unit 260 sets the time of the associated mechanical watches 100, the control unit 260 adjusts the time based on the individual differences recorded in the control unit 260. The amount of drive of the hands 151 and 152 by the hand drive section 250 may be offset by an amount corresponding to individual differences.

The time setting device for a mechanical watch, the mechanical watch, and the time setting system for a mechanical watch according to the present invention are those that align the hands that indicate the time of a mechanical watch, or those that adjust the positions of the hands. However, the pointers that are subject to alignment are not necessarily limited to only those that indicate the time, but also other points such as the year, month, day, day of the month, age of the month, aging, etc. Pointers, indicator boards, and the like that respectively indicate power reserve and the like can be targeted for positioning.

Therefore, when the time setting device for a mechanical watch according to the present invention is intended for a pointer indicating the above-mentioned year, month, day, day of the week, etc. other than the time, it can be used as a pointer positioning device for a mechanical watch. The time adjustment system for a mechanical watch according to the invention can be used as a hand position adjustment system for a mechanical watch when the system targets hands that indicate the above-mentioned year, month, day, week of the year, etc. other than the time.

<Modified examples of jumper and jumper drive vehicle>
21 and 22 are plan views showing a jumper 360 that is a modification of the jumper 160 and a jumper drive vehicle 358 that is a modification of the jumper drive vehicle 158, and FIG. 23 is a plan view showing the jumper 360 and the jumper drive vehicle shown in FIGS. 21 and 22. It is a sectional view of a main part of a car 358.

The illustrated jumper 360 is formed so that a protrusion 359a corresponding to the boss 158a of the jumper 160 can be bent so as to sink into the back side of the jumper 360. Specifically, the jumper drive vehicle 358 has a tongue piece 359 formed therein.

The tongue piece 359 has a circular arc shape extending along the circumferential direction of the jumper drive wheel 358 and is flexible. One end of the tongue piece 359 is a fixed end 359b fixed to the jumper drive wheel 358, and the other end is a free end that is not fixed, and is bent in the thickness direction of the jumper drive wheel 358 with the fixed end 359b as a fulcrum. It is possible to

A protrusion 359a that protrudes in the thickness direction of the jumper drive wheel 358 is formed at the free end of the tongue piece 359.

The protrusion 359a is formed to protrude to a height that touches the jumper 360 disposed above the front surface side (the side closer to the dial 140) of the jumper drive wheel 358. The surface of the protrusion 359a facing the fixed end 359b is an inclined surface 359d inclined with respect to the thickness direction. On the other hand, the surface of the protrusion 359a opposite to the inclined surface 359d, that is, the tip surface of the tongue piece 359, is a vertical surface 359c along the thickness direction.

When the jumper drive wheel 358 rotates clockwise as shown in FIG. 21, the vertical surface 359c of the protrusion 359a comes into contact with the side surface 361 of the jumper 360. As the jumper drive wheel 158 further rotates, the vertical surface 359c pushes the side surface 361 of the jumper 360, thereby moving the jumper 360 radially outward.

As a result, the flexible portion 363 is bent so that the radius of curvature of the flexible portion 363 having the jumper 360 formed at its tip becomes larger. The radial outward movement of jumper 360 causes jumper 360 to cover most of detection hole 156 .

As the jumper drive wheel 158 further rotates, the protrusion 359a moves and the jumper 360 further moves outward in the radial direction, causing the side surface 361 of the jumper 360 to separate from the vertical surface 359c. However, as shown in FIG. 22, the radially inner tip 360c of the jumper 360 contacts the radially outer surface 359e of the protrusion 359a, so that the state in which the jumper 360 covers most of the detection hole 156 is maintained. . The two-dot chain line in FIG. 22 shows the jumper 360 and the flexible portion 363 before the flexible portion 363 is bent.

Thereafter, further rotation of the jumper drive wheel 158 caused the protrusion 359a to separate from the tip 360c of the jumper 360, and the jumper 360 was returned to the pre-deflection position shown in FIG. 21 by the elastic force generated by the deflection of the flexible portion 363. state.

Therefore, for example, the jumper 360 moves from the outermost position to the original position in response to the pointer 151 at time 0:00:00, and at this time, the light L1 incident on the detection hole 156 passes through the jumper 360. The reflected light L2 reflected by the reflector on the back surface suddenly decreases from the maximum light intensity.

Thereby, the jumper 360 and the jumper drive vehicle 358 exhibit the same effects as the jumper 160 and the jumper drive vehicle 158.

Here, since the jumper drive wheel 358 rotates in conjunction with the hour wheel, for example, when the user of the watch 100 manually adjusts the position of the hands (time adjustment), the jumper drive wheel 358 rotates in conjunction with the movement of the hands. The jumper drive wheel 358 also rotates.

If the user aligns the pointer by rotating the pointer counterclockwise, the rotation direction of the jumper drive wheel 358 is not the clockwise direction shown in FIGS. 21 and 22, but the counterclockwise direction. Rotate in the circular direction. In this case, the inclined surface 359d of the jumper drive vehicle 358 hits the side surface 362 of the jumper 360 on the opposite side from the side surface 361.

Here, assuming that the inclined surface 359d is formed of a vertical surface similar to the vertical surface 359c, the vertical surface presses the side surface 362 of the jumper 360 in the counterclockwise direction, so that the jumper 360 moves in the radial direction. Move in a counterclockwise direction instead of outward.

For this reason, the flexible portion 363 is only pulled, and is not able to be deformed and is in a stretched state, and the jumper drive vehicle 358 also stops. Therefore, manual positioning of the pointer by the user is no longer possible.

However, in the jumper drive vehicle 358 of this modification, the surface in contact with the side surface 362 of the jumper 360 is not a vertical surface but an inclined surface 359d. The counterclockwise rotation of 358 causes the side surface 362 of the jumper 360 to push the inclined surface 359d downward.

As a result, the tongue piece 359 bends downward, and the protrusion 359a escapes below the jumper 360, as shown in FIG. The projection 359a is in contact with the lower surface 360b of the jumper 360, and the jumper driving wheel 358 is allowed to rotate counterclockwise.

When the jumper drive wheel 358 rotates counterclockwise, the protrusion 359a passes through the area where the jumper 360 is placed and is removed from the area where the jumper 360 is placed. returns to its unflexed position.

In this way, the jumper 360 and the jumper driving wheel 358 of this modification allow the jumper driving wheel 358 to rotate even when the jumper driving wheel 358 rotates counterclockwise, so that the jumper driving wheel 358 can be manually operated by the user. When aligning the pointer, positioning can also be performed by rotating the pointer counterclockwise.

Note that although the jumper 360 of this modification is formed on the free end side of the flexible portion 363, a regulating portion 364 is formed at a position farther from the fixed end side than the jumper 360. This regulating portion 364 regulates the upward displacement of the jumper 360 so that the jumper 360 does not come into contact with the back surface 140b of the dial 140 when the flexible portion 363 is bent upward, that is, toward the dial 140. It is something to do.

That is, the back surface 140b of the dial plate 140 is painted black in order to prevent or suppress reflection of the light L incident on the detection hole 156 as described above. However, the jumper 360 moves upward as the flexible portion 363 bends in the thickness direction, and when the jumper 360 moves in the radial direction while in contact with the back surface 140b, the jumper 360 slides on the back surface 140b. Therefore, there is a risk that the black paint applied to the back surface 140b may peel off.

In particular, the jumper 360 of this modification in which the protrusion 359a is in contact with the lower surface 360b of the jumper 360 is displaced upward due to the upward elastic force acting due to the deflection of the tongue piece 359 on which the protrusion 359a is formed. Easy to do.

However, by forming the restricting portion 364, upward displacement of the jumper 360 is restricted, and it is possible to prevent or suppress the jumper 360 from coming into contact with the back surface 140b of the dial 140. In addition, by suppressing the displacement (deflection amount) of the flexible portion 363 in the thickness direction, the jumper 360 is limited to deflection within a plane, and the reproducibility of the displacement within the plane of the jumper 360 (the amount of light intensity change) is reduced. (timing accuracy) can be improved.

As shown in FIGS. 21 and 22, the regulating portion 364 is formed at a position farther from the fixed end of the flexible portion 363 than the jumper 360, so that even if the flexible portion 363 is bent upward, , the restricting portion 364 is displaced to a higher position than the jumper 360. As a result, the regulating portion 364 comes into contact with the dial 140, thereby preventing or suppressing the jumper 360 from coming into contact with the dial 140.

Note that the regulating portion 364 may be formed so as to contact the dial before the jumper 360, and may be formed on the side of the flexible portion 363 closer to the fixed end than the jumper 360.

Furthermore, as shown in FIG. 23, the regulating portion 364 is formed at a position closer to the dial 140 than the jumper 360 in the thickness direction of the watch. As a result, the regulating portion 364 comes into contact with the dial 140 while the amount of deflection of the flexible portion 363 in the thickness direction is smaller. Therefore, in a state in which the restricting portion 364 hits the dial 140 and the deflection of the flexible portion 363 is restricted, a larger gap can be secured between the jumper 360 and the dial 140, and the jumper 360 contacts the dial 140. This can further prevent or deter people from coming into contact with other people.

Note that since the regulating portion 364 hits the dial 140 at a different position than the jumper 360, even if the paint on the back surface 140b of the dial 140 is peeled off by the regulating portion 364, the detection of reflected light through the detection hole 156 is not affected. do not have. However, as shown in FIG. 23, by forming the regulating part 364 into a spherical surface, the area of the regulating part 364 in contact with the dial 140 is reduced, and sliding becomes smooth, reducing the area where paint peels off. , peeling can be suppressed.

<Embodiment of a time setting system for a mechanical watch equipped with a magnetic rotating body>
FIG. 24 is a diagram showing a time setting system 300' for a mechanical timepiece 100' that includes a magnetic rotating body 380 in place of the crown 157 in the mechanical timepiece 100 shown in FIGS. 1 to 3.

The mechanical timepiece 100' has the same basic configuration as the timepiece 100, except that the crown 157 is replaced by a magnetic rotating body 380.

FIG. 25 is a plan view showing an example of the magnetic rotating body 380, and FIGS. 26 and 27 are plan views showing other examples of the magnetic rotating body. For example, as shown in FIG. 25, the magnetic rotating body 380 includes a shaft 381, a substrate 382, and permanent magnets 383 and 384. The permanent magnet 383 has an N pole, and the permanent magnet 384 has an S pole, which are arranged on the surface of the substrate 382.

The permanent magnets 383 and the permanent magnets 384 are arranged alternately along the circumferential direction centering on the axis 381 at equal angular intervals around the axis 381. The number of permanent magnets 383 and permanent magnets 374 may not be two each, but may be one each, or three or more each.

The substrate 382 is formed into a disk shape centered on the axis 381, but as shown in FIG. 26, it may be a bar-shaped substrate 385 with permanent magnets 383 and 384 arranged at both ends, As shown in FIG. 27, a substrate 387 may be formed by adding an annular substrate 386 centered on an axis 381 to a bar-shaped substrate 385.

The magnetic rotating body 380 is connected to the hands 151 and 152 via an interlocking mechanism. Further, the magnetic rotating body 380 rotates around the axis 381 due to an external magnetic field. That is, by applying a magnetic field from outside the timepiece 100, the magnetic rotating body 380 rotates, and the hands 151 and 152 can be rotated. Therefore, like the crown 157, the magnetic rotating body 380 is an example of an operating member.

Note that the magnetic rotating body 380 in the mechanical timepiece 100' is also connected to a mainspring that is a power source of the mechanical timepiece 100'. Thereby, the mainspring can also be wound up by rotating the magnetic rotating body 380. Therefore, the mechanical timepiece 100' does not need to include the rotary weight 154 that has the function of winding up the mainspring. However, a mechanism for winding up the mainspring by rotating the rotary weight 154 may be provided.

The time setting device 200' replaces the pointer driving section 250 in the time setting device 200, which drives the hands 151, 152 by operating the crown 157, and instead rotates the magnetic rotating body 380 by generating a magnetic field. The basic configuration is the same as that of time setting device 200 except that it includes a drive section 280.

Note that the rotation drive section 280 also drives the hands 151 and 152 via the magnetic rotating body 380, which is an operation section, and is therefore an example of a pointer drive section.

FIG. 28 is a plan view showing an example of the rotation drive section 280. As shown in FIG. 28, the rotation drive unit 280 includes six electromagnets 283 and 284 arranged on a substrate 282 and an electric circuit 281 that drives these electromagnets 283 and 284.

For example, the electromagnets 283 and 284 are formed so that the winding directions of the winding wires are opposite to each other, and the electromagnets 283 and 284 have opposite magnetic poles when driven by the electric circuit 281. The electromagnets 283 and 284 are arranged alternately along the circumference at equal angular intervals. The number of electromagnets 283 and 284 does not have to be three each as shown in FIG. 28, but may be one each, two each, or four or more.

The rotation drive unit 280 generates a magnetic field by magnetizing the electromagnets 283 and 284 by driving the electric circuit 281. Then, the control unit 260 changes the magnetic field by sequentially reversing the magnetic poles formed by magnetizing the electromagnets 283 and 284. As a result, the magnetic rotating body 380 of the mechanical timepiece 100', which is disposed opposite to the rotation drive unit 280, is rotated around the shaft 381.

Therefore, the time setting device 200' can adjust the time (align the hands 151, 152) and wind the mainspring of the mechanical watch 100' by rotating the magnetic rotating body 380 of the mechanical watch 100'. can.

As described above, according to the mechanical timepiece 100', the time setting device 200', and the time setting system 300' of this modification, the mechanical timepiece 100' can ’ time can be adjusted.

Further, the mechanical watch 100', the time setting device 200', and the time setting system 300' of this modification have the same functions and effects as the mechanical watch 100, the time setting device 200, and the time setting system 300 of the embodiment described above. demonstrate.

Note that according to the mechanical watch 100', the time setting device 200', and the time setting system 300' of this modification, there is no need for the mechanical watch 100' to include a crown that protrudes from the case 110. The waterproofness of the type watch 100' can be made strong.

Further, according to the mechanical watch 100', the time setting device 200', and the time setting system 300' of this modification, the time setting device 200' grips, releases, and pulls the crown 157 of the mechanical watch 100. Since an actuator that performs mechanical operations such as pushing and turning is not required, the configuration can be simplified and miniaturized.

Note that, like the mechanical timepiece 100, the mechanical timepiece 100' includes a jumper 160, a detection hole 156, etc., which are examples of the optical characteristic changing section provided in the mechanical timepiece 100. Further, the time setting device 200' also includes a hand position detection section 230 included in the time setting device 200.

Then, the hand position detection unit 230 of the time setting device 200' detects a change in the amount of light detected through the detection hole 156 in accordance with the movement of the jumper 160 of the mechanical watch 100'. Detecting the reference positions of the hands 151 and 152 is the same as in the time setting system 300 of the mechanical timepiece 100 and the time setting device 200 of the embodiments described above, so a detailed explanation will be omitted.

(Positional relationship between magnetic rotating body and detection hole)
Since the detection hole 156 is a passage for detecting changes in optical characteristics from the glass plate 132 side of the back cover 130, in the arrangement covered by the magnetic rotating body 380, changes in optical characteristics are detected by the time setting device 200. 'The pointer position detection section 230 cannot detect the point. Therefore, an example of a preferable arrangement of the detection hole 156 and the magnetic rotating body 380 in the mechanical timepiece 100' will be described below.

29 and 30 are examples of the arrangement in which the detection hole 156 and the magnetic rotating body 380 do not overlap in plan view. FIG. 29 shows an example of an arrangement in which the center of the magnetic rotating body 380 is aligned with the center of the mechanical timepiece 100' in plan view. In this arrangement example, since the center of the magnetic rotating body 380 coincides with the center of the mechanical watch 100', the weight is evenly distributed around the center, resulting in good weight balance.

FIG. 30 shows an example of an arrangement in which the center of the magnetic rotating body 380 is eccentric in the direction opposite to the detection hole 156 with respect to the center of the mechanical timepiece 100' in plan view. In this arrangement example, since the center of the magnetic rotating body 380 is eccentric from the center of the mechanical watch 100', the substrate 382 of the magnetic rotating body 380 is formed in a larger size than the substrate 382 in the arrangement example shown in FIG. Therefore, the magnetic rotating body 380 can be rotated with a weak magnetic force.

31, 32, and 33 are schematic diagrams showing an example of an arrangement in which the detection hole 156 and the magnetic rotating body 380 overlap in plan view at a specific rotational angular position of the magnetic rotating body 380, but do not overlap at other rotational angular positions. It is a diagram.

FIG. 31 shows an example of an arrangement in which the center of the magnetic rotating body 380 is aligned with the center of the mechanical timepiece 100' in plan view. In this arrangement example, when the bar-shaped substrate 385 of the magnetic rotating body 350 is at a specific rotational angular position, the substrate 385 overlaps the detection hole 156 in a plan view, but at rotational angular positions other than the overlapping rotational angular position. , the substrate 385 does not overlap the detection hole 156 in plan view.

The rotational angular position of the magnetic rotating body 380 can be controlled in relation to the magnetic field of the rotary drive section 280. Therefore, by controlling the rotation drive unit 280 by the control unit 260 of the time setting device 200', it is detected that the rotation angle range of the substrate 385 of the magnetic rotating body 380 does not overlap with the detection hole 156, and the detected rotation angle range is The control section 260 may control the operation of the pointer position detection section 230 so that the pointer position detection section 230 detects the pointer position of the mechanical timepiece 100'.

32 and 33 also show examples of arrangement in which the center of the magnetic rotating body 380 is aligned with the center of the mechanical timepiece 100' in plan view. In this arrangement example, when the substrate 387, which is a combination of a bar shape and an annular shape of the magnetic rotating body 350, is at a specific rotation angle position, the substrate 387 overlaps the detection hole 156 in a plan view (see FIG. 32); At rotational angular positions other than the rotational angular position, the substrate 387 does not overlap the detection hole 156 in plan view (see FIG. 33).

Therefore, similarly to the arrangement example shown in FIG. 31, the control section 260 of the time setting device 200' controls the rotation drive section 280 to control the rotation angle range in which the substrate 387 of the magnetic rotating body 380 overlaps the detection hole 156. (the arrangement shown in FIG. 32), the control section 260 controls the pointer position detection section 230 to prevent the pointer position detection section 230 from detecting the pointer position of the mechanical timepiece 100' in the detected rotation angle range. Controls the operation of the pointer position detection section 230.

On the other hand, when it is detected that the substrate 387 of the magnetic rotating body 380 is in a rotation angle range that does not overlap with the detection hole 156 (the arrangement shown in FIG. The control section 260 controls the operation of the pointer position detection section 230 so as to detect the pointer position of 100'.

As a result, even if the detection hole 156 and the magnetic rotating body 380 are arranged to overlap in plan view at a specific rotation angle position of the magnetic rotating body 380, the time setting device 200' can detect a change in the optical characteristics. Can be done.

34, 35, and 36 show a preferred form of the time setting device 200' in which a rotational drive section 280' made up of permanent magnets is used in place of the rotational drive section 280 made up of electromagnets 283, 284. It is a figure which shows an example.

The magnetic poles of the electromagnets 283 and 284 can be changed by changing the direction of the current using the electric circuit 281, and thus the magnetic field can be changed. However, since the magnetic poles of permanent magnets do not change, the magnetic field cannot be changed simply by changing the direction of the current, unlike the electromagnets 283 and 284.

Therefore, the rotation drive section 280' needs to rotate permanent magnets arranged on the substrate 282 instead of the electromagnets 283 and 284 together with the substrate 282, and is equipped with a motor for rotating them in this manner. The operation of this motor is controlled by the control section 260.

Furthermore, since the electromagnets 283 and 284 are magnetized and form a magnetic field only during the period when electric current is flowing through the electric circuit 281, the electromagnets 283 and 284 are magnetized only during the period of time setting operation, and the time is not set. The electromagnets 283 and 284 can be kept unmagnetized while the mechanical watch 100' is left alone.

However, permanent magnets always create a magnetic field. Therefore, a magnetic field is generated even during a period when the magnetic rotating body 380 is not rotating. Therefore, while the mechanical watch 100' is placed in the time setting device 200', it may be constantly exposed to the magnetic field.

Therefore, in the time setting device 200', when rotating the magnetic rotating body 380, the rotation drive unit 280' using a permanent magnet is placed in a position close to the mechanical watch 100, as shown by the solid line in FIG. After the magnetic rotating body 380 has finished rotating, the control unit 260 controls the mechanical watch 100 so that it is placed away from the mechanical watch 100 in the thickness direction, as shown by the two-dot chain line in FIG. It is preferable to control an actuator or the like that moves the permanent magnet.

In this way, when the magnetic rotating body 380 is not rotating, the permanent magnet is placed away from the mechanical watch 100', so that the mechanical watch 100' is placed in the time setting device 200'. During this period, exposure to the magnetic field formed by the permanent magnet can be prevented.

Note that the direction in which the permanent magnet is moved away from the mechanical watch 100' is not limited to the thickness direction of the mechanical watch 100 as shown in FIG. It may be in a direction parallel to the plane and at a position that does not overlap with the mechanical timepiece 100' in plan view.

Furthermore, instead of the configuration in which the permanent magnet is moved away from the mechanical timepiece 100', the time setting device 200' may be configured to include a magnetic shield plate 290 that shields external magnetic fields, as shown in FIG. 36.

That is, when the time setting device 200' rotates the magnetic rotating body 380, as shown by the solid line in FIG. After the magnetic rotating body 380 has finished rotating, a magnetic shielding plate is placed between the mechanical watch 100 and the rotary drive unit 280', as shown by the two-dot chain line in FIG. The control unit 260 may control an actuator or the like that moves the magnetic shield plate 290 so as to insert the magnetic shield plate 290.

In this way, when the magnetic rotating body 380 is not rotating, by placing the anti-magnetic plate 290 between the permanent magnet and the mechanical watch 100', the mechanical watch 100' can operate the time setting device 200'. It is possible to prevent the permanent magnet from being exposed to the magnetic field while the permanent magnet is placed there.

<Other variations>
The time setting device 200' of the embodiments and modifications described above has a configuration in which a pointer position detection section 230 and rotation drive sections 280, 280' are arranged on the glass plate 132 side of the back cover 130 of the mechanical timepiece 100'. However, the pointer position detection section 230 and the rotation drive sections 280, 280' may be arranged on different sides of the mechanical timepiece 100 in the thickness direction.

FIG. 37 shows a time setting device in which a pointer position detection section 230 is arranged on the glass plate 132 side of the back cover 130 of a mechanical watch 100', and a rotation drive section 280 is arranged on the windshield 120 side of the mechanical watch 100'. It is a figure which shows the example of 200'. In the time setting device 200' shown in FIG. 37, a pointer position detection section 230 is arranged on the glass plate 132 side of the back cover 130 of the mechanical timepiece 100', and a rotation drive section is arranged on the windshield 120 side of the mechanical timepiece 100'. 280 (, 280') are arranged.

In this way, by arranging the pointer position detection section 230 and the rotary drive sections 280, 280' on different sides in the thickness direction of the mechanical watch 100, the pointer position detection section 230 and the rotation drive section 280 , 280' can be arranged more freely.

Note that, contrary to the time setting device 200' shown in FIG. 37, a rotary drive unit 280 is arranged on the glass plate 132 side of the back cover 130 of the mechanical watch 100', and is arranged on the windshield 120 side of the mechanical watch 100'. The pointer position detection section 230 may be arranged at.

Further, the rotation drive unit 280 may be arranged on both the glass plate 132 side and the windshield 120 side of the back cover 130 of the mechanical timepiece 100'. According to the configuration in which the rotation drive units 280 are disposed on both sides of the mechanical timepiece 100' in the thickness direction, the magnetic rotating body 380 can be rotated with a stronger magnetic field.

FIG. 38 is a plan view showing an example of a magnetic rotating body 380 in which a bar code 389 recording information regarding the mechanical timepiece 100' is added to a substrate 382. As shown in FIG. 38, a bar code 389 recording information regarding the mechanical timepiece 100' may be added to the substrate 382 (, 385, 387) of the magnetic rotating body 380. As the information recorded as the barcode 389, information regarding individual differences among the mechanical watches 100' can be used.

That is, as described above, even if the hands 151 and 152 point to 0:00:00 at the time 0:00:00, the mechanical timepiece 100' may have an instantaneous amount of reflected light L2 due to individual differences. There are individual differences, such as the time that changes from 0:00:02 to 23:29:51.

Therefore, such individual differences in the mechanical timepiece 100' at the time of manufacture can be recorded as an optically readable barcode 289. Then, when the time setting device 200' rotates the magnetic rotating body 380, the bar code 289 is read by the bar code reading device included in the time setting device 200'. The control unit 260 stores the time difference (individual difference) at which the characteristics change.

The control unit 260 corrects the correspondence between the change in optical characteristics detected by the pointer position detection unit 230 and the positions of the hands 151 and 152 based on the stored individual differences. As a result, even if there is a deviation due to individual differences in the positions of the hands 151, 153 when the optical characteristics of each mechanical watch 100' change, the time setting device 200' can maintain accuracy for each mechanical watch 100'. You can easily set the time.
