It is configured so that it can be pressed in a possible state.

Next, the operation of the switch device 10 in this electronic wristwatch will be described.
First, a normal hand movement state in which the rotation operation member 13 of the switch device 10 is not operated will be described. In this normal hand movement state, as shown in FIG. 2, the rotation operation member 13 is pushed into the wristwatch case 1 and locked to the guide pipe 14 by the lock portion 25. In other words, the rotary operation member 13 is locked by locking the female screw portion 25 a to the male screw portion 25 b of the guide pipe 14.

  Therefore, as shown in FIG. 2, the rotation operation member 13 has the ring-shaped flange portion 27 b of the interlocking pipe 27 provided therein compressed the second coil spring 33 via the second sliding member 35. In the state, it is pushed toward the inside of the watch case 1. In this state, the retaining member 24 of the rotation operation member 13 is in contact with the stopper portion 28a of the projection 28 provided on the head 18 of the pressing operation member 12 from the outside, so that the pressing operation member 12 is It is pushed toward the inside of the case 1.

  That is, as shown in FIG. 2, the pressing operation member 12 is directed toward the inner side of the wristwatch case 1 with the head 18 compressing the first coil spring 30 via the first sliding member 32. It is pushed in. Therefore, the shaft portion 17 of the pressing operation member 12 is pressed toward the inside of the watch case 1 in the guide pipe 14.

  Further, in this state, as shown in FIG. 10, the winding stem 11 is position-restricted to the first position (normal hand movement state) by the urchin 45 of the position-restricting member 40, and the switch plate of the position-restricting member 40 47 is located between the contact portions 9a and 9b of the circuit board 9 and is in an off state in which neither of them contacts.

Next, a case where the winding stem 11 is rotated to correct the time will be described.
In this case, first, as shown in FIG. 11, the rotation operation member 13 is rotated to unlock the rotation operation member 13 with respect to the guide pipe 14. That is, when the rotation operation member 13 is rotated, the screwing of the female screw portion 25a of the rotation operation member 13 with respect to the male screw portion 25b of the flange portion 16 of the guide pipe 14 is released.

  At this time, the rotation operation member 13 moves away from the wristwatch case 1 (right side in FIG. 11) in accordance with the rotation operation for releasing the lock, and is pushed out by the spring force of the second coil spring 33. At this time, the pressing operation member 12 is also pushed by the spring force of the first coil spring 30 as the rotation operation member 13 moves, and slides in the same direction as the rotation operation member 13.

  At this time, the screw portion 22 of the winding stem 11 is screwed into the screw hole 21 provided in the shaft portion 17 of the pressing operation member 12, and the winding stem 11 is connected to the pressing operation member 12. As the pressing operation member 12 slides, the winding stem 11 slides in the direction in which it is pulled out. Then, as shown in FIG. 12, the shoreline 45 of the position restricting member 40 engaged with the engaging groove 43 of the winding stem 11 rotates with the slide of the winding stem 11 to rotate the switch plate 47. The contact spring portion 45a of the switch plate 47 is brought into contact with one contact portion 9a.

  As a result, the switch is turned on, and the mode is switched from the normal hand movement mode to the time adjustment mode. For this reason, the magnetic sensor 38 is turned on, and the magnetic field of the magnet 37 provided on the winding stem 11 can be detected. When the rotation operation member 13 is rotated in this state, the pressing operation member 12 is rotated accordingly, and the rotation of the pressing operation member 12 is transmitted to the winding stem 11, and the winding stem 11 is combined with the pressing operation member 12. Rotate. Then, since the magnet 37 rotates together with the winding stem 11, a change in the magnetic field accompanying the rotation of the magnet 37 is detected by the magnetic sensor 38, and the pointer is moved based on the detection result to correct the time.

  In this state, even if the pressing member 12 is pressed from the outside, the switch is simply turned off and the mode is not switched. That is, when the pressing operation member 12 is pressed against the spring force of the first coil spring 30, the winding stem 11 is slid in the direction in which it is pushed. Then, as shown in FIG. 10, the shoreline 45 of the position restricting member 40 engaged with the engagement groove 43 of the winding stem 11 rotates with the slide of the winding stem 11 to rotate the switch plate 47. For this reason, as shown in FIG. 10, the contact spring part 45a of the switch board 47 moves between the contact parts 9a and 9b of the circuit board 9, and it will be in the OFF state which does not contact any of them, and a mode will not switch. .

  After correcting the time in this way, the rotation operation member 13 of the switch device 10 is pushed again to return to the normal hand movement state, and the rotation operation member 13 is locked to the normal hand movement state where the rotation operation member 13 cannot be operated. In this case, when the rotary operation member 13 is pushed into the wristwatch case 1 in the state shown in FIG. 11, the fingertip comes into contact with the interlocking protrusion 29 b of the operation portion 29 in the head 18 of the pressing operation member 13. The rotation operation member 13 is pushed into the watch case 1 side while pushing the projection 29b.

  At this time, when the interlocking projection 29b is pushed, the urchin 45 of the position restricting member 40 engaged with the engaging groove 43 of the winding stem 11 rotates as the winding stem 11 slides, and the switch plate 47 As shown in FIG. 10, the contact spring portion 45 a of the switch plate 47 moves between the contact portions 9 a and 9 b of the circuit board 9 and enters an off state where it does not contact any of them. For this reason, even if the rotation operation member 13 is rotated by mistake, the magnetic sensor 38 does not detect a change in the magnetic field accompanying the rotation of the magnet 37, so that no malfunction occurs.

Next, a case where the pressing operation member 12 of the switch device 10 is pressed to switch to another function will be described.
In this case, as shown in FIG. 2, the rotation operation member 13 of the switch device 10 is locked in a normal operating state where the operation cannot be performed, and as shown in FIG. 10, the contact spring portion 45 a of the switch plate 47 is connected to the circuit board 9. Are moved between the contact portions 9a and 9b and brought into an off state in which neither of them is in contact, that is, a normal hand movement state.

  In such a normal hand movement state, when the pressing operation member 12 is pressed from the outside, the pressing operation member 12 shown in FIG. 2 resists the spring force of the first coil spring 30 to the inner side of the watch case 1 (see FIG. 2 to the left), and the winding stem 11 is pushed in as the pressing operation member 12 slides. At this time, as shown in FIG. 13, the urchin 45 of the position restricting member 40 engaged with the engaging groove 43 of the winding stem 11 rotates with the slide of the winding stem 11 to rotate the switch plate 47. . For this reason, the contact spring portion 47a of the switch plate 47 comes into contact with the other contact portion 9b to be turned on, and the switch is switched from the normal hand movement mode to another function mode.

  As described above, according to the switch device 10 of the electronic wristwatch, the rotation operation member 13 having the through hole 23 formed in the axial direction and the movement of the rotation operation member 13 into the through hole 23 can be achieved. A pressing operation that can be pressed from one opening and is provided so as not to come out from the one opening of the through-hole 23 and that rotates together with the rotating operation member 13 when the rotating operation member 13 is rotated. The member 12 and a first coil spring 30 disposed in the through hole 23 of the rotation operation member 13 and biasing at least the pressure operation member 12 in one opening direction are provided. Since it protrudes to the outside from one opening of the through hole 23 of the member 13 and has an operation portion 29 formed larger than the inner diameter of the through hole 23 at the protruding outer end portion, Good work property, and it is possible to prevent malfunction during switch operation.

  That is, in this switch device 10, when the operating portion 29 of the pressing operation member 12 is pressed and operated with the rotation operating member 13 being pushed in, the pressing area can be increased, so that the operating portion can be reliably and satisfactorily improved. 29 can be pressed. Further, when the rotary operation member 13 is pulled out and rotated and then pushed in again, the operation unit 29 can be pushed in simultaneously with the rotary operation member 1 to turn off the switch. Even if the member 13 is accidentally rotated when the member 13 is pushed in, it is possible to reliably prevent the switch from malfunctioning.

  In this case, since the operation portion 29 of the pressing operation member 12 has the interlocking protrusion 29b whose outer diameter is substantially the same as the outer diameter of the rotation operation member 13, the rotation operation member 13 is pulled out and rotated. After that, when the rotary operation member 13 is picked and pushed again, the finger holding the rotary operation member 13 naturally picks and pushes the interlocking protrusion 29b of the operation unit 29. At this time, the pressing operation member The switch can be turned off by sliding 12. For this reason, even if it rotates accidentally when pushing in the rotation operation member 13, it can prevent reliably that a switch malfunctions.

  Further, in this switch device 10, the first coil spring 30 that biases the pressing operation member 12 toward one opening direction of the through hole 23 and the rotation operation member 13 toward one opening direction of the through hole 23. By providing the second coil spring 33 to be urged, when the rotation operation member 13 is pulled out and rotated, the rotation operation member 13 is stably rotated by the spring force of the second coil spring 33. In addition, the pressing operation member 12 can be rotated in conjunction with the pressing operation member 12 in a stable state by the spring force of the first coil spring 30. For this reason, there is no backlash at the time of switch operation, and switch operation can be performed in a stable state. As a result, switch operation can be performed smoothly and satisfactorily, so that the switch operability can be improved.

  Further, according to the switch device 10, the interlocking pipe 27 that interlocks the rotation operation member 13 and the pressing operation member 12 is provided. The interlocking pipe 27 is pushed out by the pressing force of the first coil spring 30. In this state, the pressing operation member 12 is rotated in conjunction with the rotation operation of the rotation operating member 13, and in this state, the pressing operation member 12 is pressed against the spring force of the first coil spring 30. In this case, since the pressing operation member 12 is slid, the switch operability is good.

  That is, when the rotation operation member 13 is rotated while the rotation operation member 13 is pulled out, the interlocking pipe 27 engages the uneven portion 27 a of the rotation operation member 13 and the uneven portion 28 b of the pressing operation member 12. Therefore, the rotation can be transmitted to the pressing operation member 12, and the pressing operation member 12 can be reliably and satisfactorily rotated. Further, when the pressing operation member 12 is pressed in this state, the unevenness portion 27 a of the rotation operation member 13 and the unevenness portion 28 b of the pressing operation member 12 are engaged with each other. Accordingly, the pressing operation member 12 can be smoothly slid by being smoothly slid.

  Furthermore, according to the switch device 10, the rotation operation member 13 is locked in a state where the rotation operation member 13 is pushed together with the pressing operation member 12 against the spring force of the first and second coil springs 30 and 33. Since the locking portion 25 is provided, it is possible to reliably prevent an inadvertent switch operation in a normal hand movement state.

  That is, the lock portion 25 is provided on the weekly surface of the male screw portion 25 b provided on the outer peripheral portion of the flange portion 16 of the guide pipe 14 provided on the side wall portion 1 a of the watch case 1 and the through hole 23 of the rotation operation member 13. Since the rotation operation member 13 is rotated and the female screw portion 25a is screwed into the male screw portion 25b of the flange portion 16 of the guide pipe 14 and tightened, the rotation operation member 13 is provided. 13 can be securely and satisfactorily fixed and locked to the watch case 1.

  In the above-described embodiment, the case where the operation portion 29 of the pressing operation member 12 includes the disk-like interlocking protrusion portion 29b formed to have substantially the same size as the outer diameter of the rotation operation member has been described. The interlocking protrusion 29b does not necessarily have to be formed in a disc shape, and may be a disc-shaped outer peripheral portion in which a collar portion is formed in a cylindrical shape. In short, when the rotary operation member 13 is gripped with a finger Any shape may be used as long as the finger contacts and pushes the pressing operation member 12.

  In the above-described embodiment, the case where the first sliding member 32 is disposed on the inner surface of the head 18 in the pressing operation member 12 corresponding to the outer end portion side of the first coil spring 30 is described, but not limited thereto.
