Description

[Technical area]

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

[Technical background]

Mechanical watches are not equipped with electronic components such as a motor or the like inside and therefore have no function such as radio clocks that an error is automatically corrected. The time can only be set by manual actuation by the user.

To manually correct an error in the mechanical watch, however, the hands must be corrected while observing the exact present time, which is inconvenient.

Therefore, an external correcting device is proposed by which the hands of a mechanical watch placed on the device are automatically corrected (see, for example, Patent Document 1).

<Construction of the mechanical watch>

The mechanical watch 100 according to the present embodiment is not only an example of the mechanical watch according to the present invention, but also an example of the mechanical watch constituting a time setting system 300 which is an example of the time setting system of the present invention for the mechanical watch is.

The mechanical clock 100 is a purely mechanical clock that is not provided with electronic components, including batteries or the like, but is only formed from mechanical components. The mechanical watch 100 is e.g. B. a wrist watch. A cylindrical housing 110 (including a housing frame) made of a metallic material such as stainless steel, titanium or the like is formed on the mechanical watch 100, a front side of the housing 110 being closed with a windshield 120, as shown in FIG and a rear side is closed with a rear cover 130.

The windshield 120 is formed in the manner of a transparent plate, whereby a dial 140 arranged inside the mechanical watch 100 and arranged inside the mechanical watch 100, the time indicating hands 151, 152 from outside the mechanical watch 100 through the Windshield 120 are visible.

In the dial 140, a bore 141 is opened in a near half of a crown 157 mentioned below, through which a balance 153 of a clockwork 150 arranged on a rear side of the dial 140 is visible from outside the windshield 120.

The rear cover 130 is formed from an annular frame 131 formed from a metal and a disk-like, translucent glass pane 132 provided within this frame 131. As a result, the clockwork 150, which is provided closer to the rear side in the mechanical clock 100 than the dial 140, a rotating mass 154, which is provided closer to the rear cover 130 than the clockwork 150, and the like from outside the rear cover 130 through the Glass pane 132 is visible.

The clockwork 150 has a through-hole 155 extending from the front side (side of the windshield 120) to the rear side (side of the rear cover 130). The balance 153 is arranged on this through-hole 155. As a result, the balance 153 of the movement 150 is visible from outside the rear cover 130 through the glass pane 132.

The hands 151, 152 indicate a time while rotating by pointing to numerals or indices corresponding to the time and formed on the front side of the dial 140 at certain positions, respectively. The pointers 151, 152 are z. B. an hour hand to show the hour and a minute hand to show the minute. The back 140b of the dial 140 is to dampen light reflection z. B. blackened.

On the clockwork 150, the crown 157 is provided, which is connected to the pointers 151, 152 via a coupling mechanism (not shown). The crown 157 is an example of an actuating part which is designed to be able to move the hands 151, 152 from the outside. The crown 157 is arranged outside the case 110, and by rotating the crown 157, the hands 151, 152 are rotatable.

In the half of the movement 150 which is opposite to the half having the balance wheel 153 (the half further away from the crown 157), a detection bore 156 extending from the front side to the rear side is formed.

The detection hole 156 is opposite to the rear side 140b of the dial 140 on the front side, and is located opposite the rear cover 130 on the rear side. A jumper 160 is arranged on the front side of the clockwork 150, as shown in FIGS.

On the front side of the clockwork 150, a wheel row holder 162 is attached, from which a bending portion 163 extends in the shape of a circular arc, at the front end of which the jumper 160 is formed. The jumper 160 is formed integrally with the wheel row holder 162 and the bending portion 163. The wheel row holder 162, the bending portion 163 and the jumper 160 are formed from the same metal. As shown in FIG. 5, one end of the bending section 163 is connected as a fastening end to the wheel row holder 162 and the other end, on which the jumper 160 is formed, can bend in the radial direction of the clockwork 150 as a free end.

A jumper drive wheel 158 is arranged in the clockwork 150 next to the jumper 160 (on its rear side). The jumper drive wheel 158 is rotated at one-half the rotational speed (one revolution per 12 hours) of a tubular wheel to which the hand 151 (e.g., hour hand) is attached, together with the tubular wheel. Since the tubular wheel makes one revolution in a 12 hour period, the jumper drive wheel 158 makes one revolution in a clockwise direction in a 24 hour period.

On the jumper drive wheel 158, a projection 158a is formed which protrudes in a direction parallel to the rotating shaft of the jumper drive wheel 158. The projection 158 rests against a flank 161 of the jumper 160 in a predetermined angle of rotation range of the jumper drive wheel 158 in accordance with the rotation of the jumper drive wheel 158.

If the jumper drive wheel 158 is rotated further, the projection 158a presses the flank 161 of the jumper 160 outward in the radial direction in order to displace the jumper 360 outward in the radial direction. As a result, the bending section 363 bends, as shown in FIG. 5 with the solid line, to a larger radius of curvature of the bending section 163.

If the jumper drive wheel 158 is rotated to a position in which the projection 158a on the innermost peripheral edge of the flank 161 of the jumper 160 passes, the projection 158a is released from the jumper 160, the load with which the jumper 160 in the radial direction has been pushed outwards, disappears.

As a result, an elastic energy stored on the bending section 163 is released all at once in the jumper 160, which has been moved by the bending of the bending section 163 to the outermost position indicated by the dash-two-dot line in FIG. 6, so that the jumper 160 is instantaneously (for example, within one second) is brought into a state in which the jumper 160 is returned to the original position shown by the solid line (the inner position in the radial direction).

The jumper 160 is arranged in such a way that the track of the jumper 160, which is shifted from the original position (position according to FIG. 4) in which the projection 158a does not rest on the jumper 160, to the outermost position according to FIG Detection hole 156 gradually covered.

When the jumper 160 is in the original position according to FIG. 4, the bending section 163 does not bend and the jumper 160 only partially covers the detection bore 156. When the jumper 160 is at the outermost position indicated by the solid line in FIG. 5, the bending section 163 bends the most and the jumper 160 essentially completely covers the detection bore 156.

A reflection plate is provided on a rear side 160b of the jumper 160. Therefore, as shown in FIG. 3, when a light beam L1 is incident from the side of the rear cover 130 toward the front side in the detection hole 156 and the bending portion 163 does not bend and the jumper 160 is in the original position, the substantially reaches The entire incident light beam is the blackened back side 140b of the dial 140. The light beam incident on the back side 140b is absorbed by the back side 140b and the reflection is attenuated, whereby almost no reflection light L2 returns to the back cover 130 side.

On the other hand, when the jumper 160 is at the outermost position, substantially all of the incident light beam is reflected by the reflection plate provided on the rear side 160b of the jumper 160, whereby a large amount of the reflection light L2 is returned to the rear cover 130 side.

As explained above, the jumper drive wheel 158 moves together with the movement of the tubular wheel and performs one revolution per 24 hours. Therefore, the position of the projection 158a is assigned to a position of the pointer 151 in a certain time range. For example, it is specified that when the pointer 151 comes to a position corresponding to the time approximately 9 p.m., the projection 158a begins to rest on the jumper 160, and that when the pointer 151 comes to a position of the time 0 a.m. 00 minutes 00 Seconds corresponding standard position comes, the projection 158a is released from the jumper 160.

That is, the jumper 160 begins to move radially outward at around 9 p.m., is returned from the extreme position to the original position at 12:00 a.m. 00 minutes 00 seconds, and then remains in the original position and not moved until the next time around 9 p.m. is reached.

As a result, the jumper 160 moves corresponding to the pointer 151 at the time 0:00 00 minutes 00 seconds from the extreme position to the original position, the amount of light of the reflection light L2 produced by the reflection of the light beam L1 incident in the detection hole 156 by the reflection plate is generated at the back of the jumper 160, falls from the greatest amount of light at once.

Thereby, the jumper 160 changes the optical property with respect to the incident light beam L1 in the detection hole 156 based on the standard position of the pointer 151. The jumper 160 is therefore an example of the part for changing the optical property, which is adapted to a Change in the amount of light of the reflection light L2, which is a change in the optical property, can be detected from the outside through the rear cover 130.

The rotating mass 154 is used to wind up a spiral spring, which is a drive source of the mechanical watch 100, and rotates about an axis of rotation provided in the center of the movement 150. The jumper 160 is visible from the outside through the detection bore 156 within the rotary range H of the rotary mass 154.

If morning and afternoon as a time display by the hands 151, 152 of the mechanical watch 100 do not need to be differentiated from each other, the mechanical watch 100 can be designed such that the jumper drive wheel 158 is not in a 24-hour period, but in a 12 hour period. The jumper drive wheel 158 can be configured in such a way that it rotates at the same angular speed as the rotation of the tubular wheel.

<Construction of the timing device>

The time setting device 200 according to the present embodiment is not only an example of the time setting device of the present invention but also an example of the time setting device constituting the time setting system 300 which is an example of the time setting system for the mechanical watch of the present invention.

The time setting device 200 shown in FIGS. 1 to 3 is designed separately from the mechanical watch 100 and is used to set the time of the mechanical watch 100. The time setting device 200 includes a watch assembly part 220, a hand position detecting part 230, a time measuring part 240, a hand driving part 250, and a control part 260.

On the timepiece arranging part 220, the mechanical timepiece 100 is positioned and arranged at a specific position of a stand 210 which is an outer cover of the time setting device 200. Explained more concretely, the timepiece assembly part 220 abuts the outer periphery of the frame 131 of the mechanical timepiece 100 to hold the mechanical timepiece 100 in a position in which the crown 157 is directed downward and the timepiece 150 is inclined from a horizontal plane, such as shown in Figure 3.

Since the mechanical watch 100 is inclined relative to the horizontal plane in a state arranged on the watch arrangement part 220, the rotating mass 154 is due to its own weight in a region of the lower half of the movement 150, i. H. in the half close to the crown 157.

The pointer drive part 250 has a drive part 251 and a coupling shaft 252. The drive part 251 has a motor and a number of reduction gears. The coupling shaft 252 is fitted to the crown 157 of the mechanical timepiece 100 arranged on the timepiece assembly part 220 and connected to the crown 157 to transmit the rotation of the drive part 251 to the crown 157 and thereby rotate the crown 157, whereby the one with the crown 157 connected pointers 151, 152 are driven.

The hand position detection part 230 is provided at a position of the mechanical watch 100 arranged on the watch assembly part 220 in a certain position opposite the detection bore 156 through the rear cover 130. The pointer position detection part 230 is a reflective photo reflector provided with a light emitting part 231 such as an LED or the like that emits a light beam L1 toward the detection hole 156, and a light receiving part 232 that receives a reflection light L2 from the jumper 160 through the detection hole 156 , is provided.

The hand position detection part 230 is integrated with various electronic components together in a circuit board 233. To protect the pointer position detection part 230, a protective pane 211 with a light permeability permeable to the light beam L1 and the reflection light L2 is provided on an outer side of the stand 210 on which the pointer position detection part 230 is arranged.

The pointer position detection part 230 detects a change in the amount of light of the reflection light L2 coming from the jumper 160 through the detection hole 156 and thereby detects the standard position of the pointers 151, 152 corresponding to the time 0:00, 00 minutes 00 seconds.

The time measuring part 240 receives radio waves generated e.g. B. be received by so-called radio clocks and contain information about the time, and thereby measures the exact present time.

The control part 260 controls the hand drive part 250 so that the hands 151, 152 of the mechanical watch 100 based on the standard position of the hands 151, 152 corresponding to the time 0:00 00 minutes 00 seconds detected by the hand position detecting part 230 to one of those from the time measuring part 240 measured now time corresponding pointer position are driven.

The control part 260 stores the relative relationship of the drive amount of the drive part 251 to the drive amount (rotation angle) of the hands 151, 152. Based on this relative relationship, the control part 260 calculates the drive amount required to rotate the hands 151, 152 by a certain angle of the drive part 251 and controls the drive part 251.

(How the timing system for the mechanical clock works>

The timing system 300 formed with the above construction is operated as follows.

First, the mechanical timepiece 100 is placed on the timepiece arranging part 220 of the time setting device 200 in a specific position by the user. At this time, the mechanical watch 100 is in a state in which the crown 157 is at a lowermost position, the detection hole 156 of the mechanical watch 100 is opposed to the hand position detection part 230, and the crown 157 is connected to the coupling shaft 252.

If the mechanical watch 100 is arranged in the specific position on the watch assembly part 220, the rotating mass 154 is in a stationary state due to its own weight at the lowest position close to the crown 157. The side facing away from the crown 157 is on the upper side, which is why the rotating mass 154 is by no means positioned between the hand position detection part 230 and the detection bore 156, which are both formed on the upper side. Therefore, since the detection hole 156 is not covered by the rotating mass 154, the detection of the position of the hands 151, 152 by the hand position detection part 230 is not prevented.

When the user presses an unillustrated, provided in the stand 210 of the time setting device 200 start button for setting the time, the control part 260 controls the hand drive part 250 so that the hands 151, 152 of the mechanical watch in the accelerated advance at a time of 0:00 Minutes 00 seconds corresponding position.

Instead of the start button being pressed manually by the user, it is also possible that the arrangement of the mechanical watch 100 on the watch arrangement part 220 is detected by the time setting device 200 and the above-explained control is automatically started by the control part 260 on the basis of this detection result .

The detection of the placement of the mechanical watch 100 on the watch assembly part 220 can, for. B. by detecting the change in the amount of received light detected by the light receiving part 232 of the hand position detecting part 230 (change in the amount of light from a received light amount of ambient light where the mechanical watch 100 is not arranged to a received light amount where the mechanical watch 100 is arranged) respectively.

The control part 260 drives the drive part 251 to rotate the coupling shaft 252 connected to the drive part 251 and also the crown 157 connected to this coupling shaft 252, whereby the hands 151, 152 in the accelerated advance with a relative to the normal rotation for the Time display to be rotated higher speed.

While the hands 151, 152 are being rotated at the accelerated rate, the light emitting part 231 of the pointer position detecting part 230 emits a light beam L1 toward the detection hole 156, and the light receiving part 232 continuously receives a reflection light L2 from the jumper 160 and waits for detection a moment when the amount of light of the received reflection light L2 instantly drops.

The moment when the amount of received light of the reflection light L2 from the jumper 160 drops instantly, corresponds, as explained above, to the moment when the jumper 160 is returned from the extreme position to the original position and the pointers 151, 152 the Time 0 o'clock 00 minutes 00 seconds take the corresponding standard position.

By the hand position detecting part 230 detecting the moment of change in which the amount of light of the reflection light L2 received by the hand position detecting part 230 drops instantly, the standard position of the hands corresponding to the time 0:00 00 minutes 00 seconds is detected. At this detected moment, the hand position detection part 230 detects that the hands 151, 152 of the mechanical watch 100 are at the standard position corresponding to the time 0:00 00 minutes 00 seconds, and the control part 260 detects the standard position of the hands 151, 152.

The control part 260 controls the pointer drive part 250 such that the hands 151, 152 of the mechanical watch 100, which indicate the standard position corresponding to the time 0:00 00 minutes 00 seconds, are driven in the accelerated advance and so in one of the time measuring part 240 measured current time can be brought into the corresponding position.

At the time point at which the hands 151, 152 have been driven to a position corresponding to the present time, the control part 260 executes control to stop the drive of the hand driving part 250, and ends the operation of the hand position detecting part 230 (the light output from the light emitting part 231 is stopped, and the light receiving operation and the detecting operation for the amount of received light by the light receiving part 232 are stopped).

As explained above, the time setting system 300 for the mechanical watch 100 according to the present embodiment does not analyze the image of the dial 140 and the hands 151, 152. Therefore, by the time setting system 300 for the mechanical watch 100 according to the present embodiment a highly precise time setting of the mechanical watch 100 independent of the shape or the like of the dial 140 and the hands 151, 152 of the mechanical watch 100 take place.

FIG. 7 is a perspective view of the jumper 160 in which the bending displacement of the bending portion 163 is restricted by a bending restriction member.

In the mechanical timepiece 100 of the time setting system 300 according to the present embodiment, the time point of a change in the optical property caused by the change in movement of the jumper 160 (steeply decreasing change in the amount of reflected light) is detected. Slight fluctuations in the bending of the bending section 163 can result in deviations in the movement of the jumper 160.

In order to reduce deviations in the bending of the bending section 163, as shown in FIG. 7, a bending restriction part can be provided which restricts the bending section 163 with regard to the bending direction. The bend restriction part is e.g. B. from a groove part 164, which extends outward from a region of the bending section 163 close to the jumper 160 in the radial direction of the clockwork 150, in which the jumper 160 is displaced, and an inserted into the groove part 164 attached to the clockwork 150 Pin 159 formed.

With the bend restricting part formed with the above construction, the jumper 160 is displaced outwardly in the radial direction while restricting the groove part 164 by the pin 159 outwardly in the radial direction. When the jumper 160 is returned to its original position, the jumper 160 is also displaced inward in the radial direction by restricting the groove part 164 by the pin 159. Thereby, deviations in the bending of the bending portion 163 can be reduced.

FIG. 8 is a schematic view of the mechanical watch 100 in which the detection bore 156 is formed within the range of rotation H of the rotating mass 154.

On the mechanical watch 100 of the time setting system 300 according to the present embodiment, the detection bore 156 is formed within the range of rotation H of the rotating mass 154, as shown in FIG. Since the timepiece assembly part 220 of the time setting device 200 accommodates the mechanical timepiece 100 in a position in which the half in which the detection hole 156 is formed is on the upper side and the half that is free from the detection hole 156 is on the lower side , the rotating mass 154 is prevented from being disposed between the detection hole 156 and the hand position detection part 230.

The time setting system 300 according to the present embodiment is not limited to this embodiment. Namely, it is also possible to use the clock assembly part 220 of the time setting device 200 e.g. B. to be designed so that it receives the mechanical watch 100 in a position in which the half in which the detection hole 156 is formed is on the lower side.

FIG. 9 is a schematic view of a mechanical watch 100 corresponding to FIG. 8, in which an opening 154c, such as a small window, a recess or the like, is formed in a region of the rotating mass 154, one of which is the detection bore 156 and the straight line connecting the pointer position detecting part 230 passes.

With the above construction, the rotating mass 154, which stands still by its own weight on the lower side, can be arranged between the detection bore 156 and the pointer position detection part 230. The mechanical watch 100, such as. For example, as shown in FIG. 9, an opening 154c, such as a small window, a recess or the like, is formed in a region of the rotating mass 154 through which a straight line connecting the detection bore 156 and the pointer position detection part 230 runs. This can prevent the detection of the optical change by the pointer position detection part 230 from being disturbed through the detection bore 156.

FIG. 10 is a schematic view of a mechanical watch 100 corresponding to FIG. 8, in which the detection bore 156 is formed in the radial direction outside the range of rotation H of the rotating mass 154.

As shown in FIG. 10, the mechanical watch 100 can be designed in such a way that the detection bore 156 is formed in the radial direction outside the rotation area H of the rotating mass 154 (or the rotating mass 154 can be designed such that the rotating area H of the rotating mass 154 is limited to an area which lies further inside in the radial direction than the detection bore 156 (rotating mass 154 with a small radius)).

Even if the rotary mass 154 stands still in any angular position within the rotation range H of the rotary mass 154, the rotary mass 154 is not arranged between the detection bore 156 and the pointer position detection part 230. Therefore, as shown in FIG. 10, the detection bore 156 can also be formed on the lower half in which the rotating mass 154 will stand still. In this embodiment, too, the detection of the optical change by the pointer position detection part 230 can be prevented from being disturbed through the detection bore 156.

FIG. 11 is a sectional view of a mechanical watch 100 corresponding to FIG. 3, in which a tubular light-shielding tube 171 is provided in an intermediate region between the clockwork 150 and the glass pane 132, which corresponds to an area of the detection bore 156 extended to the glass pane 132.

In the mechanical watch 100, in which the detection bore 156 is formed in the radial direction outside the range of rotation H of the rotating mass 154, it is preferred that a tubular light shielding tube 171, as shown in Figure 11, in an intermediate area between the clockwork 150 and of the glass pane 132 is provided, which corresponds to a region of the detection bore 156 which is extended to the glass pane 132.

On the mechanical timepiece 100 formed with the above construction, the rotated rotating mass 154 does not interfere with the light shielding tube 171, which prevents z. B. through a hole 141 of the dial 140 and a through hole 155 of the clockwork 150 to the rear side of the clockwork 150 is incident outside light L3 in a light path of the between the hand position detection part 230 and the detection hole 156 reciprocating light beam L1 and reflection light L2. As a result, influences of the outside light L3 can be excluded, so that the pointer position detection part 230 can detect a change in the amount of light of the reflection light L2 with high accuracy.

Instead of the light shielding tube 171 or in addition to the light shielding tube 171, an optical fiber 172 in which a light for conduction is completely reflected can be provided between the detection hole 156 and the glass pane 132. Thereby, scattering of the light beam L1 and reflection light L2 reciprocating between the pointer position detection part 230 and the detection hole 156 to the outside can be prevented or attenuated.

FIG. 12 is a sectional view of a mechanical watch 100 corresponding to FIG. 3, in which a light shielding tube 171 and an optical fiber 172 are provided and in which the spiral spring is wound up by manual actuation.

The provision of the light shielding tube 171 and the optical fiber 172 between the movement 150 and the glass plate 132 is not limited to the mechanical watch 100 in which the detection hole 156 is formed outside the rotation range H of the rotating mass 154 in the radial direction. As shown in FIG. 12, the light shielding tube 171 and the optical fiber 172 can also be provided in a mechanical watch 100 which does not have a rotating mass 154 and in which the so-called spiral spring is wound by manual actuation, since no rotating mass 154 interferes here.

In one embodiment, e.g. B. in accordance with FIG. 3, in which the rotating mass 154 has a large range of rotation H and the detection bore 156 is arranged within this range of rotation H, no light shielding tube 171 and no optical fiber 172 can be provided.

However, in a construction in which the bore 141 of the dial 140 and the through-hole 155 of the clockwork 150 are within the rotating range H, the rotating mass 154 covers which in the state in which the mechanical watch 100 is positioned on the watch assembly part 220 , located on the lower side, the through hole 155.

Therefore, an outside light L3 can be prevented from being incident in the light path of the light beam L1 and reflection light L2 reciprocating between the pointer position detection part 230 and the detection hole 156 by, for example, blackening the front side 154a of the rotating mass 154 and thereby through outside light L3 incident on the through hole 155 is absorbed by the front side 154a.

The mechanical timepieces 100 used in the time setting systems 300 of the above embodiments are formed such that the detection hole 156 passes through the timepiece 150 and that, when the jumper 160 is in the original position, one of the light emitting part 231 of the hand position detecting part 230 emitted light beam L1 is absorbed by the blackened rear side 140b of the dial 140 and is thus almost not reflected.

FIG. 13 is a sectional illustration of a mechanical watch 100 corresponding to FIG. 3, in which the detection bore 156 does not pass through the movement 150.

However, the mechanical watch 100 is not limited to the above embodiments. It is also possible that the detection bore 156 does not pass through the movement 150, as shown in FIG. The bottom surface (end face) 150b of the detection bore 156 can be designed in such a way that it does not reflect the light beam L1.

In the mechanical watch 100 formed with the above construction, the bottom surface 150b of the detection hole 156 has the same effect as the back 140b of the dial 140 in the mechanical watch 100 according to FIG. 3. Therefore, this mechanical watch 100 can be used as a mechanical watch in the time setting system 300 of the present embodiment can be used.

The mechanical watches 100 used in the time setting systems 300 of the above embodiments are designed such that the rear side 160b of the jumper 160 has a reflection plate and the reflection light L2 reflected by the jumper 160 is received by the light receiving part 232. However, the time setting system of the present invention is not limited to this embodiment.

FIG. 14 is a sectional view of a mechanical watch 100 corresponding to FIG. 3, which is designed in such a way that the rear side 140b of the dial 140 is provided with a reflection plate 143 and the rear side 160b of the jumper 160 absorbs the light beam L1.

The mechanical clocks 100 used in the time setting systems 300 of the above embodiments can namely, as shown in Figure 14, be designed such that the back 140b of the dial 140 is provided with a reflective plate 143 and the back 160b of the jumper 160 the light beam L1 absorbed.

In this time setting system 300, the hand position detecting part 230 of the time setting device 200 detects a smallest amount of light of the reflection light L2 when the jumper 160 is at the extreme position and a largest amount of light of the reflection light L2 when the jumper is returned to the original position corresponding to the standard position of the pointers 151, 152 160.

Therefore, at the time when the detected light amount of the reflection light L2 changes from the smallest to the largest amount of light, the hand position detecting part 230 can detect that the hands 151, 152 are at the standard position.

In the timing systems 300 of the above-mentioned embodiments, the hand position detecting part 230 has a light emitting part 231 that emits a light beam L1 toward the detection hole 156 from the light emitting part 231. It is also possible that the hand position detecting part 230 of the time setting device 200 does not have a light emitting part 231.

FIG. 15 is a sectional view of a mechanical watch 100 corresponding to FIG. 3, in which a bore 144 for introducing external light L4 into the detection bore 156 is formed in the dial 140 opposite the detection bore 156, and from the outside through the bore 144 of the dial 140 Outside light L4 introduced into the detection bore 156 is shielded by the jumper 160.

In this case, such as. For example, in the embodiment shown in FIG. 15, a bore 144 for introducing outside light L4 into the detection bore 156 may be formed in the dial 140 opposite the detection bore 156 and the outside light L4 introduced from outside the mechanical watch 100 through the bore 144 of the dial 140 into the detection bore 156 shielded by jumper 160.

In this time setting system 300, the hand position detecting part 230 (light receiving part 232) of the time setting device 200 detects a smallest amount of light of the outside light L4 when the jumper 160 is located at the extreme position and a largest amount of light of the outside light L4 when corresponding to the standard position of the hands 151, 152 in the original position returned jumper 160.

Therefore, at the time when the detected light amount of the outside light L4 changes from the smallest to the largest light amount, the hand position detection part 230 can detect that the hands 151, 152 are at the standard position.

FIG. 16 is a sectional view of a mechanical watch 100 corresponding to FIG. 3, in which the light emitting part 231 and the light receiving part 232 are not adjacent to one another, but are spaced from one another, so that the detection bore 156 is on a light path that the light beam emitted by the light emitting part 231 L1 passes through, and a light path through which the reflection light L2 reflected by the jumper 160 is directed toward the light receiving part 232 is divided.

In the timing systems 300 of the above-mentioned embodiments, the light emitting part 231 and the light receiving part 232 of the hand position detecting part 230 are juxtaposed and arranged as an integral photoreflector. However, as shown in FIG. 16, the mechanical timepiece 100 can be formed with a construction in which the light emitting part 231 and the light receiving part 232 are not adjacent to each other but are spaced apart from each other so that the detection hole 156 is on a light path that the light emitting part 231 emitted light beam L1 passes, and a light path through which the reflection light L2 reflected by the jumper 160 is directed to the light receiving part 232 is divided.

With the timing system 300 constructed with the above construction, the same effect as the timing systems of the above-mentioned embodiments can be obtained.

FIG. 18 is a view of a day disk (day wheel) 180 which is used instead of the jumper 160 as part for changing the optical property and which rotates once a day only in a certain time range.

In the time setting systems 300 of the present embodiments, the jumper 160 of the mechanical watch 100 is used as a part for changing the optical property. It is also possible, instead of the jumper 160, to use a day disk (day wheel) 180, which rotates once a day only in a predetermined time range, as part for changing the optical property, as shown in FIGS. 17 and 18.

For example, a pattern by which the optical property can be changed is formed on the rear side 180b of the day disk 180. Explained more concretely, the day disk 180 rotates per day by an angular range J, the respective angular ranges J, as shown in FIG Colors are divided. The light beam L1 is not reflected but absorbed by the non-reflective section 181. By the reflecting portion 182, the light beam L1 is reflected, and a reflection light L2 is emitted.

Before the time 0:00, 00 minutes 00 seconds corresponding to the standard position of the hands 151, 152, the day disc 180 is in a state in which a non-reflective portion 181 opposes the detection hole 156 and becomes 0:00 00 minutes at the time 00 seconds switched to a state in which a reflective portion 182 of the detection hole 156 is opposite.

As a result, the mechanical watch 100 can be provided with the day disk 180 instead of the jumper 160 as a part for changing the optical property.

FIG. 19 is a view of a gear wheel 190 which is used instead of the jumper 160 as a part for changing the optical property.

Instead of the jumper 160, the gear wheel 190 shown in FIG. 19 and provided with a bore 191 can also be used as part for changing the optical property. The gear wheel 190, like the jumper drive wheel 158 according to FIG. 4, performs one revolution every 24 hours. If it is made so that the bore 191 is opposed to the detection bore 156 at 0:00 00 minutes 00 seconds, the hand position detecting part 230 can detect the standard position of the hands 151, 152 by changing the reflection light L2.

In the present invention, the optical property changing part is not limited to changing the optical property in a 24-hour period. For example, a part can also be provided that z. B. to increase the resolution of the change in the optical property acts in such a way that it changes the optical property in a one-hour period (operated once per hour), so that by a combination of several parts that change the optical property in different periods, the accuracy of changing the optical property can be increased.

In the present invention, the optical property changing part is not limited to changing the above-mentioned amount of light, reflection rate, or transmittance of the reflection light L2. It is also possible for the part to change a single or a combination of several of the following properties in order to change the optical property: phase, optical path length, polarization direction, wavelength, hue, refraction, beam direction, focal point and the like.

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

In order to reduce stray light in the mechanical watch or the time setting device, the inside of the mechanical watch or the inside of the time setting device may be colored in light-absorbing black.

In the time setting systems 300 of the present embodiments, an instantaneous change in the amount of light of the reflection light L2 generated by the jumper 160 of the mechanical watch 100 occurs at the time when the standard position of the hands 151, 152 is 0:00 00 minutes 00 seconds corresponds to. However, the point in time of the standard position of the hands 151, 152 at which the jumper 160 produces an instantaneous change in the amount of light of the reflection light L2 is not limited to the point in time corresponding to the time 0:00, 00 minutes 00 seconds. Any time corresponding to any time can be selected for this.

In the time setting systems 300 and the time setting devices 200 of the above-mentioned embodiments, the position of the hands 151, 152 is detectable only at the standard position of the hands 151, 152 corresponding to a certain time (e.g. time 0:00 00 minutes 00 seconds) . In the present invention, the time setting system and the time setting device can be configured to detect a position of the hands 151, 152 of the mechanical watch 100 corresponding to an arbitrary time.

The mechanical watches 100 of the present embodiments are designed in such a way that the balance wheel 153 which is characteristic of the mechanical watch 100 is visible. However, the mechanical timepiece and time setting system of the present invention are not limited to the fact that the balance wheel 153 is externally visible. It is also possible to design it so that the balance 153 cannot be seen from the outside.

FIG. 20 is a schematic view of two types of adapters 221, 222, each corresponding to two types of mechanical watches 100 ', 100 "with different external shapes, and for positioning and arranging these mechanical watches 100', 100" on the watch arrangement part 220 are releasably provided.

The time setting device 200 of the present embodiment may be configured as shown in FIG. 20, having detachably plural kinds of adapters 221, 222 on the watch assembly part 220, through which plural kinds of mechanical watches 100 ', 100 "respectively correspond to the plural kinds mechanical clocks with different external shapes (e.g. a mechanical clock 100 'with a diameter D1 and a mechanical clock 100 "with a diameter D2 (<D1)) can each be positioned at a specific position.

In this time setting device 200, two types of mechanical clocks 100 ', 100 "with different external shapes can optionally be placed on a time setting device 200 only in that either the adapter 221 corresponding to the mechanical clock 100' with the diameter D1 or that of the mechanical clock 100 ″ with the diameter D2 corresponding other adapter 222 is additionally attached to the clock assembly part 220. As a result, the costs can be reduced in comparison with an embodiment in which a time setting device 200 for exclusive use is provided for each of the two types of mechanical watches 100 ′, 100 ″ with different external shapes.

In the time setting device 200 according to FIG. 20, a different mechanical watch 100 with a different external shape than the two types of mechanical watches 100 ', 100 "can be arranged on the watch assembly part 220 without the adapters 221, 222 additionally attached to the watch assembly part 220 are.

The time setting device of the present invention may be provided with a plurality of hand position detection parts so that the time setting device can be adapted not only to the above-mentioned several types of mechanical watches having different external shapes as watches to be arranged, but also to several types of mechanical watches in which the position of the part for changing the optical property varies, can be used.

In the time setting systems 300 of the present embodiment, the hands 151, 152 are driven to set the time in a state where the mechanical timepiece 100 is attached to the time setting device 200. Instead of driving the hands, the crown 157 can be driven to wind the spiral spring. The mechanical watch 100 can be designed in such a way that, in accordance with the direction of rotation of the crown 157, a switch is made between an actuation to drive the pointers 151, 152 and an actuation to wind the spiral spring.

In the time setting systems 300 of the present embodiment, the hands 151, 152 of the mechanical watch 100 are driven and time setting is performed by pressing the time setting start button in a state where the mechanical watch 100 is attached to the time setting device 200 pressed by the user. If the mechanical timepiece 100 continues to be arranged on the time setting device 200 after the time setting, time setting can be repeated every specified time interval or at a specified time even if the time setting start button is not pressed thereafter.

Furthermore, the time setting systems 300 of the present embodiments can be configured such that, after setting the time by driving, the hands 151, 152 of the mechanical watch 100 are in a state in which the mechanical watch 100 is arranged on the time setting device 200 , the mechanical watch 100 is still arranged on the time setting device 200, the mechanical watch 100 is not operated by the driving force of the coil spring of the mechanical watch 100, but the control part 260 controls the hand drive part 250 so that whenever the time measuring part 240 of the time setting device 200 measures the time the position of the hands 151, 152 is adjusted.

At this time, the time of the mechanical watch 100 is continuously set by the time setting device 200 during the period in which it is attached to the time setting device 200, and therefore the same accuracy as that of a radio controlled watch is maintained. Therefore, the mechanical watch 100 can always be kept in a state in which it is set to the accurate time when it is removed from the time setting device 200.

The mechanical timepieces 100 of the above-mentioned embodiments are set such that at the specific point of time 0:00, 00 minutes 00 seconds, the amount of light of the reflection light L2 is instantly changed. Nonetheless, in real mechanical watches 100, individual differences can arise due to manufacturing errors within the design tolerances of the components or an accumulation of errors resulting from the combination of components.

Therefore, although the hands 151, 152 of the manufactured mechanical watches 100 show the time at 0:00 00 minutes 00 seconds "0:00 00 minutes 00 seconds", it is possible due to the individual differences that the time at which the amount of light of the reflection light L2 is instantly changed, in a mechanical watch 100 it is 0 o'clock 00 minutes 02 seconds, and in another mechanical watch 100 it is 23 o'clock 29 minutes 51 seconds.

If, in spite of these individual differences of the mechanical watches 100, the time setting device 200 does not perform a time setting of the respective mechanical watches 100 in consideration of the individual differences, the positions of the hands 151, 152 are offset by the respective individual differences from time.

Therefore, individual differences in manufacture should be recorded in the respective mechanical watches 100 and the time setting device 200 should read the individual differences recorded in the mechanical watches 100 when the mechanical watches 100 are set and drive the hands 151, 152 in such a way that the hands 151, 152 show a time offset by an amount corresponding to the individual differences read.

Since the mechanical timepieces 100 are not provided with electronic components, a semiconductor memory or the like cannot be used for recording the above-mentioned individual differences.

Therefore, a sticker o. The like. On which the respective mechanical watches 100 corresponding individual differences as a code, z. B. as a one-dimensional or two-dimensional barcode, and with which information is thus recorded in a non-electronic manner, glued to the back cover 130 or the housing 110 of the mechanical watches 100, whereby the individual differences can be recorded.

Here, the time setting device 200 can be provided with a reading part for reading the code represented as a one-dimensional or two-dimensional barcode, and the control part 260 can receive the individual differences corresponding to the code read by the reading part and the drive size of the pointers 151, 152 by the Move the pointer drive part 250 by an amount corresponding to the obtained individual differences.

Since the watch main body including the movement 150 of the mechanical watch 100 is not provided with electronic components, an RFID tag or the like in which individual differences are electronically recorded can be incorporated in a watch band other than a watch main body be.

Here, the time setting device 200 may be provided with a reading part for wirelessly reading the information about the individual differences recorded in the RFID tag, and the control part 260 can obtain the individual differences based on the information about the individual differences read by the reading part and offset the drive amount of the hands 151, 152 by the hand drive part 250 by an amount corresponding to the obtained individual differences.

In the time setting system 300 for the mechanical watch 100 in which a mechanical watch 100 and a time setting device 200 are associated with each other as a set of one-to-one correspondence, the individual difference of the associated mechanical watch 100 in the control part 260 of the time setting device 200 are recorded in advance, and when the control part 260 performs time adjustment of the associated mechanical timepiece 100, the control part 260 can offset the drive amount of the hands 151, 152 by the hand drive part 250 by an amount corresponding to the individual difference based on the individual difference recorded in the control part 260 .

According to the present invention, the time setting device for the mechanical watch, the mechanical watch and the time setting system for the mechanical watch themselves perform position adjustment of the time indicating hands of the mechanical watch or correspond to mechanical watches suitable for position adjustment of the hands . However, the subject of position adjustment is not necessarily limited to only the hands showing the time. The object of the position adjustment can also be a pointer, an indicator plate or the like.

<Variant example of the jumper and the jumper drive wheel>

21 and 22 are top views of a jumper 360 and a jumper drive wheel 358 according to a varied example of the jumper 160 and the jumper drive wheel 158. FIG. 23 is a sectional view through the essential parts of the jumper 360 and the jumper drive wheel 358 according to FIGS 22nd

The jumper 360 shown in the drawings is designed in such a way that an elevation 359a corresponding to the projection 158a on the jumper 160 can bend in such a way that it sinks onto the rear side of the jumper 360. More specifically, a tongue 359 is formed on the jumper drive wheel 358.

The tongue 359 is formed in the manner of an arc of a circle extending along a circumferential direction of the jumper drive wheel 358, and is flexible. One end of the tongue 359 is designed as a fastening end 359b fastened to the jumper drive wheel 358, and the other end is designed as a non-fastened free end, whereby the tongue 359 can bend around the fastening end 359b in the direction of the thickness of the jumper drive wheel 358.

At the free end of the tongue 359, the elevation 359a is formed, which protrudes in the thickness direction of the jumper drive wheel 358.

The elevation 359a protrudes to a height at which the elevation 359a can impinge on the jumper 360 disposed above the front side (the side near the dial 140) of the jumper drive wheel 358. The surface of the elevation 359a facing the fastening end 359b is designed as a ramp 359d which is beveled in relation to the thickness direction. The surface of the elevation 359a facing away from the ramp 359d, d. H. the end face of the tongue 359 is formed as a vertical surface 359c running in the thickness direction.

When the jumper drive wheel 358, as shown in FIG. 21, is rotated clockwise, the vertical surface 359c of the elevation 359a hits a flank 361 of the jumper 360. When the jumper drive wheel 158 is rotated further, the vertical surface 359c presses the flank 361 of the jumper 360, thereby displacing the jumper 360 in the radial direction outward.

As a result, the bending portion 363, at the front end of which the jumper 360 is formed, bends such that the radius of curvature of the bending portion 363 is increased. As a result of the displacement of the jumper 360 in the radial direction outwards, the jumper 360 covers a predominant part of the detection bore 156.

If the jumper drive wheel 158 is rotated further, the jumper 360 is displaced further outward in accordance with the movement of the elevation 359a in the radial direction, as a result of which the flank 361 of the jumper 360 is released from the vertical surface 359c. However, since a radially inner front end 360c of the jumper 360, as shown in FIG. 22, rests against a radially outer surface 359e of the elevation 359a, the state in which the jumper 360 covers most of the detection bore 156 is maintained. In FIG. 22, the two-dot chain line denotes the jumper 360 and the bending section 363 before the bending section 363 is bent.

Thereafter, the elevation 359a is released from the front end 360c of the jumper 360 by a further rotation of the jumper drive wheel 158. The jumper 360 is returned to the position shown in FIG. 21 before the bend by an elastic force generated by the bending of the bending section 363.

The jumper 360 is corresponding to the pointer 151, e.g. B. at the time 0 o'clock 00 minutes 00 seconds, shifted from the extreme position to the original position, the amount of light of the reflection light L2 resulting from the reflection of the light beam L1 incident in the detection hole 156 by the reflection plate on the back of the jumper 360 results, drops steeply from the greatest amount of light.

As a result, the jumper 360 and the jumper drive wheel 358 develop the same effect as the jumper 160 and the jumper drive wheel 158.

The jumper drive wheel 358 is rotated along with the movement of the tube wheel. Therefore, if z. For example, if the user of the watch 100 manually adjusts the position (time correction) of the hands, the jumper drive wheel 358 is also rotated along with the movement of the hands.

When the user adjusts the position of the pointers by rotating the pointers counterclockwise, the jumper drive wheel 358 is not rotated clockwise, as in FIGS. 21 and 22, but counterclockwise. The ramp 359d of the jumper drive wheel 358 strikes a flank 362 of the jumper 360 that is remote from the flank 361.

If it is assumed here that the ramp 359d is designed as a vertical surface identical to the vertical surface 359c, this vertical surface presses the flank 362 of the jumper 360 in a counterclockwise direction, whereby the jumper 360 is not radially outward but in the opposite direction is shifted clockwise.

As a result, the bending portion 363 is only pulled. The bending portion 363 cannot perform bending deformation and is brought into a tensioned state, and the jumper drive wheel 358 is stopped. As a result, position adjustment of the hands by manual operation by the user is no longer permitted.

In the case of the jumper drive wheel 358 of the present varied example, the surface impinging on the flank 362 of the jumper 360 is not a vertical surface, but the ramp 359d. After the ramp 359d hits the flank 362 of the jumper 360, the flank 362 of the jumper 360 pushes the ramp 359d downward in accordance with the counterclockwise rotation of the jumper drive wheel 358.

As a result, the tongue 359 bends downward, as shown in FIG. 23, and the elevation 359a yields under the jumper 360. In a state in which the elevation 359a rests on the underside 360b of the jumper 360, the jumper drive wheel 358 is allowed to rotate in the counterclockwise direction.

By rotating the jumper drive wheel 358 counterclockwise, the elevation 359a passes the area in which the jumper 360 is arranged. When the bump 359a leaves the area in which the jumper 360 is arranged, the bump 359a is returned to a non-bent state by the elastic force of the bending of the tongue 359.

In the case of the jumper 360 and the jumper drive wheel 358 of the present varied example, the rotation of the jumper drive wheel 358 is allowed in this way even when the jumper drive wheel 358 is rotated in the counterclockwise direction. Therefore, when the position of the pointer is set manually by the user, the position can also be set by turning the pointer counterclockwise.

According to the present varied example, the jumper 360 is formed at the free end of the bending portion 363. At a position farther from the attachment end than the jumper 360, a restriction part 364 is formed. The restriction member 364 restricts upward displacement of the jumper 360 such that the jumper 360 does not contact the back side 140b of the dial 140 when the bending portion 363 moves upward, i.e. H. bends to the side of dial 140.

As mentioned above, the back side 140b of the dial 140 is blackened in order to prevent or attenuate the reflection of the light beam L incident in the detection hole 156. When the jumper 360 is displaced upward in the thickness direction by a bend in the bending section 363 and is displaced in the radial direction in a state in contact with the rear side 140b, the jumper 360 drags along the rear side 140b. As a result, the black paint applied to the rear side 140b can be peeled off.

On the jumper 360 of the present varied example, in which the elevation 359a can rest on the underside 360b of the jumper 360, in particular an upwardly directed elastic force acts through a bend of the tongue 359 on which the elevation 359a is formed, which is why the jumper 360 can be moved upwards more easily.

If the restricting member 364 is nevertheless formed, the upward displacement of the jumper 360 is restricted, which can prevent or dampen the jumper 360 from contacting the back side 140b of the dial 140. By restricting the displacement (bending amount) of the bending portion 363 in the thickness direction, the movement of the jumper 360 is restricted to a bend in a plane, whereby the reproducibility of the displacement of the jumper 360 in a plane (accuracy of the timing of the change in the amount of light) can be increased.

As shown in FIGS. 21 and 22, since the restricting member 364 is formed at a position of the bending portion 363 that is farther from the attachment end than the jumper 360, the restricting member 364 is displaced to a higher position than the jumper 360 even when the bending portion 363 is bent upward. By having the restricting member 364 contact the dial 140, the jumper 360 can be prevented or avoided from touching the dial 140.

The restriction part 364 may be formed such that the restriction part 364 hits the dial earlier than the jumper 360. The restriction part 364 may also be formed at a position of the bending portion 363 that is closer to the attachment end than the jumper 360.

As shown in FIG. 23, the restriction part 364 is formed in the thickness direction of the watch at a position closer to the dial 140 than the jumper 360 Dial 140 on. As a result, in a state in which the restricting member 364 abuts the dial 140 and the bending of the bending portion 363 is restricted, a larger distance can be provided between the jumper 360 and the dial 140, whereby the jumper 360 can be prevented or avoided more effectively comes into contact with the dial 140.

Since the restricting member 364 is incident on the dial 140 at a different position than the jumper 360, the detection of the reflection light through the detection hole 156 is not affected even if the restricting member 364 removes the paint from the back 140b of the dial 140 . When the restricting part 364 is formed in a dome shape as shown in FIG. 23, the area of the restricting part 364 abutting the dial 140 is reduced and the displacement is smooth, thereby reducing the area on which the paint is peeled off and at the same time inhibiting the peeling can be.

<Embodiment of the time setting system for the mechanical watch with a magnetic rotator>

FIG. 24 is a view of a time setting system 300 'for a mechanical watch 100' which, instead of the crown 157 of the mechanical watch 100 according to FIGS. 1 to 3, is provided with a magnetic rotator 380.

The mechanical watch 100 'basically has the same construction as the watch 100, only the crown 157 is replaced by a magnetic rotator 380.

Figure 25 is a plan view of an example of the magnetic rotator 380. Figures 26 and 27 are plan views of other examples of the magnetic rotator. The magnetic rotator 380 is such. B. shown in Figure 25, provided with a shaft 381, a plate 382 and permanent magnets 383, 384. The permanent magnets 383 are arranged with the N pole and the permanent magnets 384 with the S pole on the surface of the circuit board 382.

The permanent magnets 383 and the permanent magnets 384 are arranged along the circumferential direction around the shaft 381 alternately at an equal angular distance with respect to the shaft 381. It is not necessary for two of the permanent magnets 383 and the permanent magnets 384 to be provided, but rather one magnet or three or more magnets can be provided in each case.

The circuit board 382 is formed like a disk around the shaft 381. The board can, however, also be used as a bar-like board 385 according to FIG. 26, in which a permanent magnet 383, 384 is arranged at both ends, or as a board 387 according to FIG. 27, in which the bar-like board 385 has a board 386 shaped as a ring around the shaft 381 is added.

The magnetic rotator 380 is connected to the pointers 151, 152 via a coupling mechanism. The magnetic rotator 380 is rotated around the shaft 381 by an external magnetic field. This means that the magnetic rotator 380 is rotated when a magnetic field is applied to the watch 100 from the outside, and the hands 151, 152 can thus be rotated. Therefore, like the crown 157, the magnetic rotator 380 is an example of the operating member.

The magnetic rotator 380 of the mechanical watch 100 'is also connected to the coil spring which is the drive source of the mechanical watch 100'. This allows the coil spring to be wound up by rotating the magnetic rotator 380. The rotating mass 154, which has an effect for winding up the spiral spring, can therefore be dispensed with on the mechanical watch 100 ′. However, it is also possible that the mechanism for winding up the spiral spring is provided by rotating the rotating mass 154.

The time setting device 200 'has basically the same construction as the time setting device 200, except that a rotation driving part 280 is provided instead of the hand driving part 250 of the time setting device 200 in which the hands 151, 152 are driven by operating the crown 157 in which the magnetic rotator 380 is rotated by generating a magnetic field.

The rotation driving part 280 also serves to drive the hands 151, 152 via the magnetic rotator 380 which is an operating part, and is therefore an example of the hand driving part.

FIG. 28 is a plan view of an example of a rotation drive part 280. As shown in FIG. 28, the rotation drive part 280 is provided with six electromagnets 283, 284 arranged on a circuit board 282 and an electrical circuit 281 for driving these electromagnets 283, 284 .

On the electromagnet 283 and the electromagnet 284 windings, for. B. wound in mutually opposite directions, so that the electromagnets 283 and the electromagnets 284 when energized by the electrical circuit 281 form mutually reversed magnetic poles. The electromagnets 283 and the electromagnets 284 are arranged alternately along the circumference at an equal angular distance. It is not necessary to provide three of the electromagnets 283 and the electromagnets 284, as shown in FIG. 28, but one electromagnet, two electromagnets or four electromagnets or more can be provided.

By being excited by the electric circuit 281, the respective electromagnets 283, 284 of the rotation driving part 280 are magnetized, and thereby magnetic fields are generated. The polarity of the magnetic poles generated by the magnetization of the respective electromagnets 283, 284 is reversed one after the other by the control part 260, as a result of which the magnetic fields vary. Thereby, the magnetic rotator 380 of the mechanical timepiece 100 ′ disposed opposite to the rotation drive part 280 is rotated around the shaft 381.

In the time setting device 200 ', therefore, time setting of the mechanical watch 100' (position adjustment of the hands 151, 152) and winding of the coil spring can be performed by rotating the magnetic rotator 380 of the mechanical watch 100 '.

By the mechanical timepiece 100 ', the time setting device 200' and the time setting system 300 'of the present varied example, time setting of the mechanical timepiece 100' can thus be performed regardless of the shape or the like of the dial 140 and the hands 151, 152 take place.

The mechanical timepiece 100 ', the time setting device 200' and the time setting system 300 'of the present varied example further exert the same effect and effect as the mechanical watches 100, the time setting devices 200 and the time setting systems 300 of the above-mentioned embodiments.

With the mechanical watch 100 ', the time setting device 200' and the time setting system 300 'of the present varied example, the crown of the mechanical watch 100' protruding outward from the case 110 can be dispensed with. Thereby, the water resistance of the mechanical watch 100 'can be enhanced.

Furthermore, through the mechanical watch 100 ', the time setting device 200' and the time setting system 300 'of the present varied example, the time setting device 200' does not require an actuator that performs mechanical operations such as grasping and releasing, pulling, pushing and holding on the mechanical watch 100 Turning the crown 157 executes. This can simplify and downsize the construction.

The mechanical watch 100 ', like the mechanical watch 100, is provided with a jumper 160, which is an example of the part for changing the optical property, and a detection hole 156 and the like of the mechanical watch 100. The time setting device 200 ′ is also provided with a hand position detecting part 230 as the time setting device 200 has.

The hand position detecting part 230 of the time setting device 200 'detects the change in the amount of light corresponding to the movement of the jumper 160 of the mechanical watch 100' to be detected through the detection hole 156, whereby the standard position of the hands 151, 152 of the mechanical watch 100 'is detected. Since this point is the same as the mechanical timepieces 100, the time setting devices 200, and the time setting systems 300 of the above-mentioned embodiments, explanation of this point is omitted.

(Positional relationship of the magnetic rotator and the detection hole)

The detection hole 156 is a path from the glass plate 132 side of the back cover 130 and serves to detect the change in optical property. Therefore, if the detection hole 156 is arranged so as to be covered by the magnetic rotator 380, the hand position detection part 230 of the time setting device 200 'cannot detect a change in the optical property. Therefore, an example of a preferred arrangement of the detection hole 156 and the magnetic rotator 380 in the mechanical watch 100 'will be explained below.

FIGS. 29 and 30 show an arrangement example in which the detection bore 156 and the magnetic rotator 380 do not overlap in plan view. FIG. 29 shows an arrangement example in which the center of the magnetic rotator 380 is matched to the center of the mechanical watch 100 ′ in plan view. In this arrangement example, since the center of the magnetic rotator 380 is matched to the center of the mechanical watch 100 ', the weight is evenly distributed around the center, so that the weight balance is good.

FIG. 30 shows an arrangement example in which the center of the magnetic rotator 380 is eccentric in a direction opposite to the detection bore 156 with respect to the center of the mechanical watch 100 ′ in plan view. In this arrangement example, since the center of the magnetic rotator 380 is eccentric from the center of the mechanical watch 100 ', the circuit board 382 of the magnetic rotator 380 can be formed in a larger size than the circuit board 382 of the arrangement example of FIG a weaker magnetic force can be rotated.

Figures 31, 32 and 33 are schematic views of arrangement examples in which the detection bore 156 and the magnetic rotator 380 are superimposed in plan view in certain rotational angle positions of the magnetic rotator 380, but not superimposed in other rotational angle positions.

FIG. 31 shows an arrangement example in which the center of the magnetic rotator 380 is matched to the center of the mechanical watch 100 ′ in plan view. In this arrangement example, a rod-like circuit board 385 of the magnetic rotator 350 is superimposed on the detection bore 156 in certain rotational angle positions in plan view. However, in other rotational angle positions than the rotational angle positions in the superposition, the circuit board 385 does not overlay the detection bore 156 in plan view.

The rotational angular position of the magnetic rotator 380 can be controlled by the relationship with the magnetic field of the rotation drive part 280. It can therefore be provided that, by controlling the rotation drive part 280 by the control part 260 of the time setting device 200 ′, it is detected that the circuit board 385 of the magnetic rotator 380 is not located in a rotational angle range in which the circuit board 385 overlaps the detection bore 156, the control part 260 controls the operation of the hand position detecting part 230 so that the hand position detecting part 230 detects the hand position of the mechanical watch 100 'in this detected rotational angle range.

FIGS. 32 and 33 show an example of an arrangement in which the center of the magnetic rotator 380 is likewise adapted to the center of the mechanical watch 100 ′ in plan view. According to this arrangement example, a circuit board 387 of the magnetic rotator 350, which is composed of a rod-like part and an annular part, is superimposed on the detection bore 156 in a plan view in certain rotational angle positions (see FIG. 32). In other rotational angle positions than the rotational angle positions in the superposition, however, the board 387 does not superimpose the detection bore 156 in plan view (see FIG. 33).

[0193] Therefore, as in the arrangement example according to FIG. 31, it can be provided that when it is detected by the control of the rotation drive part 280 by the control part 260 of the time setting device 200 'that the circuit board 387 of the magnetic rotator 380 is in a rotation angle range , in which the circuit board 387 is superimposed on the detection bore 156 (arrangement according to FIG. 32), the control part 260 controls the operation of the hand position detection part 230 in such a way that the hand position detection part 230 does not perform any operation to detect the hand position of the mechanical watch 100 'in this detected rotational angle range.

If it is detected that the circuit board 387 of the magnetic rotator 380 is not located in a rotational angle range in which the circuit board 387 overlaps the detection bore 156 (arrangement according to FIG. 33), the control part 260 controls the operation of the pointer position detection part 230 in such a way that the Hand position detection part 230 detects the hand position of the mechanical watch 100 'in this detected rotational angle range.

As a result, the time setting device 200 'can detect a change in the optical property even if, in this arrangement, the detection bore 156 and the magnetic rotator 380 are superimposed at certain rotational angle positions in a plan view.

Figures 34, 35 and 36 are views of preferred shape examples in which a rotation drive part 280 'made of permanent magnets is used on the timing device 200' instead of the rotation drive part 280 made up of electromagnets 283, 284.

In the electromagnets 283, 284, the magnetic poles can be alternated by switching the current direction through the electrical circuit 281. This means that the magnetic fields are variable. However, since the magnetic poles are not alternated in permanent magnets, the magnetic fields cannot be varied by switching the current direction alone, as in the case of electromagnets 283, 284.

Therefore, it is necessary that the rotation drive part 280 'rotates the permanent magnets arranged on the circuit board 282 instead of the electromagnets 283, 284 together with the circuit board 282. For this rotation, the rotation driving part 280 'is provided with a motor. The operation of this motor is controlled by the control part 260.

The electromagnets 283, 284 are magnetized only during the period of time supplied with electricity by the electric circuit 281 to thereby form magnetic fields. Therefore, the electromagnets 283, 284 can be brought into a state in which they are magnetized only during the time setting period and are not magnetized during the period when no time setting is performed and the mechanical watch 100 'is only put on.

Nevertheless, the permanent magnets always form magnetic fields. Therefore, the permanent magnets form magnetic fields even during the period in which the magnetic rotator 380 is not being rotated. Therefore, it is possible that the mechanical watch 100 'is continuously exposed to the magnetic fields during the period in which the mechanical watch 100' is placed on the time setting device 200 '.

It is therefore preferred that in the time setting device 200 ', the control part 260 controls an actuator or the like for moving the permanent magnets in such a way that the rotation drive part 280' with the permanent magnets, as shown in FIG of the mechanical watch 100 is placed when the magnetic rotator 380 is rotated, and after the completion of the rotation of the magnetic rotator 380, the rotation drive part 280 ', as indicated by the two-dot chain line in Fig. 34, at a thickness direction from the mechanical watch 100 remote position.

In this way, by arranging the permanent magnets at a position away from the mechanical watch 100 'during the period in which the magnetic rotator 380 is not being rotated, a state in which the mechanical watch 100' is during the period in which the mechanical watch 100 'is only placed on the time setting device 200' is exposed to the magnetic fields generated by the permanent magnets.

As the direction in which the permanent magnets are removed from the mechanical watch 100 ', not only the thickness direction of the mechanical watch 100 according to FIG. 34, but also a direction running parallel to the plane of the mechanical watch 100', which can be used , as shown by the dashed two-dot line according to FIG. 35, is at the position which does not overlap the mechanical watch 100 'in plan view.

Instead of a construction in which the permanent magnets are removed from the mechanical watch 100 ', the time setting device 200' can also be constructed with a construction with an anti-magnetic plate 290 for shielding external magnetic fields, as shown in FIG .

It can be provided that in the time setting device 200 'the control part 260 controls an actuator or the like for moving the antimagnetic plate 290 in such a way that the antimagnetic plate 290, as shown in FIG Gap between the mechanical timepiece 100 and the rotation drive part 280 'with the permanent magnets removed position when the magnetic rotator 380 is rotated, and after the rotation of the magnetic rotator 380 is completed, the anti-magnetic plate 290 as shown in Fig. 36 by the two-dot chain line indicated, is inserted into the gap between the mechanical watch 100 and the rotation drive part 280 '.

By placing the anti-magnetic plate 290 in the gap between the permanent magnets and the mechanical watch 100 'during the period in which the magnetic rotator 380 is not rotated in this way, a state in which the mechanical watch can be prevented 100 'during the period in which the mechanical watch 100' is only placed on the time setting device 200 ', is exposed to the magnetic fields generated by the permanent magnets.

(Another varied example)

The time setting devices 200 'according to the above embodiments and the varied examples are formed in a construction in which the hand position detecting part 230 and the rotation driving part 280, 280' are arranged on the glass plate 132 side of the back cover 130 of the mechanical watch 100 ' . However, it is also possible to arrange the hand position detecting part 230 and the rotation driving part 280, 280 'on other sides in the thickness direction of the mechanical watch 100.

Figure 37 is a view of an example of the time setting device 200 'in which the hand position detecting part 230 is arranged on the glass 132 side of the back cover 130 of the mechanical watch 100' and the rotation drive part 280 is arranged on the windshield 120 side of the mechanical watch 100 'is arranged. In the time setting device 200 'of Figure 37, the hand position detecting part 230 is arranged on the glass plate 132 side of the back cover 130 of the mechanical watch 100', and the rotation drive part 280 ('280') is arranged on the windshield 120 side of the mechanical watch 100 ' .

With this construction, in which the hand position detecting part 230 and the rotation driving part 280, 280 'are arranged on other sides in the thickness direction of the mechanical watch 100, the degree of freedom of arrangement of the hand position detecting part 230 and the rotation driving part 280, 280' can be increased.

Furthermore, it is also possible that, opposite to the time setting device 200 'of FIG. 37, the rotation drive part 280 is arranged on the side of the glass pane 132 of the rear cover 130 of the mechanical watch 100' and the hand position detection part 230 is arranged on the side of the windshield 120 the mechanical watch 100 'is arranged.

Furthermore, it is also possible that the rotation drive part 280 is arranged on both the glass plate 132 side of the rear cover 130 and the windshield 120 side of the mechanical watch 100 '. With this construction in which the rotation driving part 280 is disposed on both sides in the thickness direction of the mechanical watch 100 ', the magnetic rotator 380 can be rotated by stronger magnetic fields.

FIG. 38 is a plan view of an example of the magnetic rotator 380 in which a bar code 389 in which information about the mechanical watch 100 'is recorded is mounted on the circuit board 382. As shown in FIG. 38, it is also possible that a barcode 389, in which information about the mechanical watch 100 'is recorded, is attached to the circuit board 382 (, 385, 387) of the magnetic rotator 380. As information recorded in this barcode 389, information about the individual differences of the mechanical watches 100 'or the like can be used.

As explained above, the mechanical watches 100 'have individual differences, by means of which it is possible that the time at which the amount of light of the reflection light L2 is instantly changed is 0 o'clock 00 minutes 02 in a mechanical watch 100' Seconds and in another mechanical watch 100 'is at 23 o'clock 29 minutes 51 seconds, although the hands 151, 152 of the mechanical watches 100' show "0 o'clock 00 minutes 00 seconds" at 0 o'clock 00 minutes 00 seconds.

The individual differences between the mechanical watches 100 ′ can be recorded in an optically readable barcode 289 during manufacture. When the magnetic rotator 380 is rotated by the time setting device 200 ', the barcode 289 is read by a barcode reader provided on the time setting device 200', whereby the deviation (individual difference) specific to the mechanical watch 100 'in the time at which the optical property is changed , is stored in the control part 260.

The control part 260 carries out a correction on the basis of the stored individual difference with regard to the mutual relationship of the change in the optical property to the position of the pointers 151, 152 detected by the pointer position detection part 230. As a result, the time setting device 200 'can set the time with high accuracy for the individual mechanical watches 100', even if the mechanical watches 100 'have individual differences in the position of the hands 151, 152 at the time of the change in optical properties.
