On the surface of the face portion 321, portions where the start button 52 and the stop button 62 are respectively provided are stepped down in a fan shape, and these portions serve as button arrangement portions 3211 and 3212, respectively.
As shown in FIG. 4, a stepped hole 3211A in which the start button 52 is disposed is formed in the button arrangement portion 3211 so as to penetrate along the thickness direction of the timepiece 1A.
Although not shown, the button arrangement portion 3212 is formed with a hole similar to the stepped hole 3211A, and the stop button 62 is arranged in this hole.

Here, as shown in FIG. 4, the start button 52 faces the internal button 51 as the first button provided in the module 2 inside the case 3 and is positioned so that the internal button 51 can be pushed. Yes. That is, the start button 52 is a second button that links the internal button 51. As with the start button 52, the stop button 62 (FIG. 1) is also opposed to the internal button 61 as the first button inside the case 3 and can be pushed in conjunction with the internal button 61. It is configured as.
These internal buttons 51 and 61 are respectively disposed in recesses 315 and 316 formed in the body portion 31, and are hidden by the side surface portion 322 of the glass edge 32 provided along the outer periphery of the side surface 313 of the body portion 31. .
That is, the side surface portion 322 functions as a hidden portion that hides the internal buttons 51 and 61 while being the portion of the glass edge 32 that holds the cover glass 39.

The internal button 51 includes a shaft portion 511 provided so as to be able to appear and retract with respect to the module 2, and a head portion 512 provided on one end side of the shaft portion 511 and in contact with the start button 52.
One end side of the shaft portion 511 is inserted into a coupling 511A that is provided in the hole 314 of the body portion 31 and guides the protruding and retracting operation of the shaft portion 511, and is prevented from being detached by the C ring 511B.
A rubber tube 513 is provided between the coupling 511 </ b> A and the head portion 512 as a first urging unit that urges the internal button 51. The rubber tube 513 urges the internal button 51 in the direction from the inner side to the outer side of the body portion 31 and is in close contact with the periphery of the shaft portion 511 to ensure the water tightness of the case 3.

A slope 512A that gradually moves away from the position of the start button 52 is formed on the surface of the timepiece 1A of the head portion 512 in the direction from the inside of the body portion 31 toward the outer peripheral side. On the other hand, the back surface side of the timepiece 1 </ b> A of the head portion 512 is a flat portion 512 </ b> B extending along the axial direction of the shaft portion 511, and the flat portion 512 </ b> B is supported by a protruding portion 315 </ b> B formed on the body portion 31. .
The outer peripheral shape of the inclined surface 512A of the head portion 512 is an arc shape R centered around the center of the dial 11 (FIG. 1) of the timepiece 1A as shown in FIG. It has become.

The start button 52 has substantially the same structure as the internal button 51, and has a shaft portion 521 and a head portion 522 that are substantially the same as the shaft portion 511 and the head portion 512 of the internal button 51, but these shaft portion 521 and head portion are the same. 522 is integrally formed. Further, the head portion 522 is formed in a flat shape without forming the inclined surface 512A like the internal button 51, and is finished with a mirror surface by polishing, a ground pattern, plating, or the like.
The shaft portion 521 of the start button 52 is inserted through a stepped hole 3211 </ b> A formed in the glass edge 32 and is disposed along a direction substantially orthogonal to the axial direction of the internal button 51.

The second urging means provided on the start button 52 is a coil spring 523 having a larger urging force than the rubber tube 513. The coil spring 523 is disposed between a receiving seat 521C provided on the coupling 521A and the head portion 522.
The start button 52 is not rattled by the packing 521D provided on the coupling 521A, and the operational feeling is good.

On the other hand, as with the start button 52, the stop button 62 (FIG. 1) is opposed to the internal button 61 as the first button inside the case 3, and is a second button that can be pressed in conjunction with the internal button. It is configured.
Since the stop button 62 and the internal button 61 are configured in the same manner as the start button 52 and the internal button 51, illustration and description thereof are omitted.

The interlocking operation of the start button 52 and the internal button 51 of the timepiece 1A described above will be described with reference to FIGS.
In the state where the start button 52 is not pushed in, as shown in FIG. 4, the shaft portion 521 of the start button 52 and the head portion 512 of the internal button 51 are separated from each other, but the head portion 522 of the start button 52 is moved to the timepiece 1A. As shown in FIG. 6, the shaft portion 521 of the start button 52 comes into contact with the inclined surface 512 </ b> A formed on the head portion 512 of the internal button 51. Then, as the start button 52 is pushed into the back side of the timepiece 1A along the slope 512A of the internal button 51, the flat surface portion 512B is guided on the protruding portion 315B of the body portion 31, and the shaft portion 511 of the internal button 51 is connected to the module 2. Move towards. By the movement of the internal button 51, an operation signal for starting timing is input to the module 2.
That is, when the start button 52 slides on the slope 512A formed on the internal button 51, the pushing direction of the start button 52 along the thickness direction of the timepiece 1A is converted into the plane direction of the timepiece 1A, and the internal button 51 is Since it is interlocked, it is possible to operate from the front side of the timepiece 1A instead of the normal button operation operated on the side surface of the case 3.

  Here, since the urging force by the rubber tube 513 is smaller than the urging force by the coil spring 523, when the start button 52 is pushed, the repulsive force of the internal button 51 is small, and the pressing force to the start button 52 is the internal button 51. It can be transmitted smoothly and a good pressing feeling can be obtained. On the other hand, when the push of the start button 52 is released, the start button 52 having a larger urging force has a larger amount of movement to the original position than the internal button 51. Therefore, the start button 52 and the internal button 51 are Interference with each other when pushed back can be avoided.

Further, since the outer peripheral portion of the slope 512A of the internal button 51 has an arc shape R (FIG. 5), an error occurs in the assembly of the body 31 and the glass edge 32, and the position of the internal button 51 and the start button 52 Even if the position of the start button 52 varies in the rotational direction with respect to the center of the dial 11, the start button 52 is reliably in sliding contact with the internal button 51. Therefore, the internal button 51 is pushed into the module 2 without any problem by pushing the start button 52.
Note that the stop button 62 and the internal button 61 are linked in the same manner as the start button 52 and the internal button 51 are linked.

According to such 1st Embodiment, there exist the following effects.
(1) In the structure in which the start button 52 and the internal button 51 (or the stop button 62 and the internal button 61) of the timepiece 1A are interlocked, the internal button 51 and the internal button 61 that do not need to be exposed to the outside are concealed. In addition to the original function of the glass edge 32 for holding the cover glass 39, the glass edge 32 is also used to hide the internal buttons 51 and 61. As a result, a dedicated component for hiding the internal buttons 51 and 61 is not required, so that the size of the timepiece 1A does not increase and the number of components does not increase, so that the cost can be reduced.
Further, the side surface portion 322 of the glass edge 32 is provided symmetrically with respect to the center of the dial 11 surrounding the outer periphery of the side surface 313 of the body portion 31 and has a harmonious appearance. It does not become unpleasant as in the case where a member for concealing is added separately. In other words, the appearance design is not restricted by the added components, so that the appearance can be improved.

(2) Considering the model development of the watch, the body 31 having the recesses 315 and 316 with respect to the existing model in which the push buttons corresponding to the internal buttons 51 and 61 are provided on the side of the body, By using the glass edge 32 provided with the start button 52 and the stop button 62 and having the side surface portion 322, the timepiece 1A can be provided.
That is, a module common to the existing model can be used, and a model that can be pushed in from a direction different from the pushing direction of the internal buttons 51 and 61 can be easily realized by changing only the exterior parts.
Furthermore, by changing the position of the start button 52 and the stop button 62 and changing the pushing direction in various directions such as the plane direction, thickness direction, and diagonal direction of the watch 1A, many models with different designs using the same module are developed. It becomes possible to do.

(3) Since the outer peripheral portions of the internal buttons 51 and 61 are formed in an arc shape with respect to the approximate center of the dial plate 11, the variation in the positions of the internal button 51 and the start button 52 in the mutual rotation direction is absorbed and the start button 52 can be brought into sliding contact with the internal button 51 (or the internal button 61 and the stop button 62 in the same manner).
As a result, the internal button 51 can be reliably pushed by the pushing operation of the start button 52.

(4) Since the urging force by the rubber tube 513 is smaller than the urging force by the coil spring 523, when the start button 52 is pushed in or when the pushing to the start button 52 is released as described above, It is possible to prevent the internal button 51 and the start button from being rubbed and worn within the body portion 31.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
