  As shown in FIGS. 1 to 3, the first restricting portion is an inner end portion 12 c of the small diameter cylindrical portion 12 a of the cylindrical member 12 with which the outer surface of the drive gear 9 abuts. In this case, the small-diameter cylindrical portion 12a of the cylindrical member 12 is configured such that an inner end portion 12c projects into the wristwatch case 1 and the outer surface of the drive gear 9 abuts against the projected inner end portion 12c.

  Thereby, as shown in FIGS. 1 to 3, when the operation member 8 slides toward the outside of the watch case 1, the first restricting portion has a small diameter cylinder whose outer surface of the drive gear 9 is a cylindrical member 12. The position of the drive gear 9 is regulated by contacting the inner end 12c of the portion 12a. For this reason, the drive gear 9 is configured to slide relatively along the gear attachment portion 16 of the shaft portion 14 of the operation member 8 in a state where the drive gear 9 is engaged with the inner ring 6.

  In this case, the inner end portion 14c of the shaft portion 14 of the operation member 8, that is, the inner end portion 14c of the gear mounting portion 16, can be brought into contact with and separated from the inner side surface of the drive gear 9, as shown in FIGS. A retaining member 18 such as an abutting E-ring is attached. The retaining member 18 is attached to a mounting groove portion 14b provided in the inner end portion 14c of the shaft portion 14 of the operation member 8. When the operation member 8 slides toward the outside of the watch case 1, the drive gear 9 It is comprised so that it may contact | abut to the inner surface of this.

  In addition, as shown in FIGS. 1 to 3, the retaining member 18 slides the operation member 8 toward the outside of the watch case 1, and the drive gear 9 extends along the gear mounting portion 16 of the shaft portion 14. When sliding relatively, by contacting the inner surface of the drive gear 9, the position of the drive gear 9 is regulated, and the drive gear 9 is prevented from coming off from the gear mounting portion 16 of the shaft portion 14 and falling off. It is configured.

  On the other hand, as shown in FIGS. 1 to 3 and 5, the second restricting portion is a stopper portion 5 b of the middle frame 5 with which the inner surface of the drive gear 9 abuts. In this case, the middle frame 5 is provided with an insertion port 5a through which the inner end portion 14c of the shaft portion 14 of the operation member 8 is inserted together with the retaining member 18, and a drive gear is provided at the edge of the insertion port 5a. A stopper portion 5 b with which the inner surface of 9 abuts is provided so as to protrude toward the drive gear 9.

  As shown in FIG. 5, the second restricting portion is configured such that the operation member 8 slides toward the inside of the wristwatch case 1, and the inner end portion of the shaft portion 14 of the operation member 8 is attached to the inner frame together with the retaining member 18. 5 is configured such that the position of the drive gear 9 is regulated by the inner surface of the drive gear 9 coming into contact with the stopper portion 5b of the middle frame 5 when inserted into the insertion slot 5a. Therefore, the drive gear 9 is configured to slide relatively along the gear mounting portion 16 of the shaft portion 14 in a state where the drive gear 9 is engaged with the inner ring 6.

  Thus, as shown in FIGS. 1 and 5, the position restricting portion 10 includes an inner end portion 12 c of the cylindrical member 12 that is the first restricting portion and a stopper portion of the middle frame 5 that is the second restricting portion. When the operating member 8 slides toward the outside of the wristwatch case 1 by sandwiching the driving gear 9 with 5b, the driving gear 9 is moved at the inner end 12c of the cylindrical member 12 which is the first restricting portion. When the operation member 8 slides toward the inside of the wristwatch case 1, the position of the drive gear 9 is restricted by the stopper portion 5b of the middle frame 5 that is the second restriction portion.

  Thereby, the drive gear 9 is moved when the operation member 8 slides toward the outside of the watch case 1 and when the operation member 8 slides toward the inside of the watch case 1 as shown in FIGS. 1 and 5. In the state where the drive gear 9 is engaged with the inner ring 6, the position is restricted by the first restricting portion and the second restricting portion of the position restricting portion 10, and is relatively moved along the gear mounting portion 16 of the shaft portion 14. It is configured to slide.

  Further, as shown in FIGS. 1 to 3, between the cylindrical member 12 and the operation member 8, the operation member 8 is pushed out toward the outside of the watch case 1, that is, the operation member 8 is set to the first position. An urging spring member 20 is provided. The spring member 20 is a coil spring, and is disposed on the outer periphery of the shaft portion 14 of the operation member 8 so as to be positioned in the cylindrical head portion 13b of the head portion 13 and the large-diameter cylindrical portion 12b of the cylindrical member 12. It is provided between the inner end surface and the inner surface of the large-diameter head 13 a of the head 13.

  Thereby, as shown in FIG. 1, the operation member 8 is urged in the direction of being pushed toward the outside of the watch case 1 by the spring force of the spring member 20, and the head portion 13 and the shaft portion 14 are in the first direction. The retaining member 18 comes into contact with the inner surface of the drive gear 9, and the outer surface of the drive gear 9 contacts the inner end 12 c of the cylindrical member 12 that is the first restricting portion of the position restricting portion 10. By being in contact with each other, the drive gear 9 is configured to be regulated at the pushed-out first position while being engaged with the inner ring 6.

  Further, as shown in FIG. 5, when the head 13 is pushed toward the inside of the watch case 1 against the spring force of the spring member 20, the shaft portion 14 has the second portion as shown in FIG. 5. The inner end portion 14c of the shaft portion 14 of the operation member 8 is inserted into the insertion port 5a of the middle frame 5 together with the retaining member 18, and the inner surface of the drive gear 9 is moved to the stopper portion 5b of the middle frame 5. By abutting, the drive gear 9 is configured to be regulated at the pushed-in second position in a state where the drive gear 9 is engaged with the inner ring 6.

  Further, as shown in FIGS. 1 and 5, the wristwatch case 1 is provided with a switch portion 11 that performs a switch operation in response to a slide operation of the operation member 8. The switch unit 11 switches the timepiece mode between a normal timepiece mode and another mode, such as an orientation mode or a world time mode.

  As shown in FIG. 5, the switch portion 11 is pushed by the inner end portion 14 c of the shaft portion 14 of the operation member 8 when the operation member 8 is pushed against the spring force of the spring member 20. Operates and is configured to switch the clock mode from the normal clock mode to another mode. Further, as shown in FIG. 1, when the operating member 8 is pushed out by the spring force of the spring member 20, the switch portion 11 is turned off because the inner end portion 14 c of the shaft portion 14 of the operating member 8 is separated. The watch mode is configured to switch to the normal watch mode.

Next, the operation of the switch device 7 in this wristwatch will be described.
Normally, as shown in FIG. 1, the operation member 8 provided so as to be able to rotate and slide on the cylindrical member 12 fixed in the through hole 1 a of the watch case 1 is attached to the watch case 1 by the spring force of the spring member 20. It is biased in the direction of pushing outward, that is, in the first position of the operation member 8. As a result, the head portion 13 and the shaft portion 14 of the operation member 8 move to the first position where they are pushed out.

  At this time, in a state where the position of the drive gear 9 is regulated by the inner end portion 12 c of the cylindrical member 12 that is the first regulating portion of the position regulating portion 10, the shaft 14 of the operation member 8 is placed on the inner surface of the driving gear 9. The retaining member 18 attached to the inner end portion 14 c abuts, and the outer surface of the drive gear 9 is pressed against the inner end portion 12 c of the small diameter cylindrical portion 12 a of the cylindrical member 12. Thus, the position of the operating member 8 is restricted to the first position where the operating member 8 is pushed out while the drive gear 9 is engaged with the inner ring 6.

  At this time, since the inner end portion 14c of the shaft portion 14 of the operation member 8 is separated from the switch portion 11, the switch portion 11 is turned off, the watch mode is switched to the normal watch mode, and the normal watch operation is performed. Do. As a result, the display unit of the timepiece module 4 displays information such as the current time, and the timepiece movement moves the hands to indicate the current time.

  In this state, since the drive gear 9 is engaged with the inner rotation ring 6, when the head 13 of the operation member 8 is rotated, the drive gear 9 rotates with the rotation of the head 13, and the inner rotation The ring 6 is rotated. As described above, even when the inner ring 6 rotates, the timepiece mode is set to the normal timepiece mode by the switch unit 11, so that the normal timepiece mode operation is performed.

  In addition, by rotating the inner ring 6 on this wristwatch, the azimuth scales displayed on the inner ring 6 are moved to the east, west, north and south direction scales and the world time world scales. 5, the head 13 of the operating member 8 may be pressed against the spring force of the spring member 20 and the head 13 of the operating member 8 may be rotated in this state as shown in FIG. .

  That is, when the head portion 13 of the operation member 8 is pressed against the spring force of the spring member 20, the second position where the head portion 13 and the shaft portion 14 of the operation member 8 are pushed in as shown in FIG. The inner end portion 14c of the shaft portion 14 turns on the switch portion 11. That is, when the head portion 13 of the operating member 8 is pressed against the spring force of the spring member 20, the inner end portion 14 c of the shaft portion 14 of the operating member 8 together with the retaining member 18 is inserted into the insertion port 5 a of the middle frame 5. Is inserted into the timepiece module 4 and the switch section 11 is turned on.

  As a result, the switch unit 11 switches the timepiece mode from the normal timepiece mode to another mode, such as an orientation function mode or a world time function. At this time, the inner surface of the drive gear 9 abuts against a stopper portion 5b provided at the edge of the insertion port 5a of the middle frame 5, and the position of the drive gear 9 is regulated while being engaged with the inner ring 6. The inner end portion of the cylindrical head portion 13b in the head portion 13 of the operation member 8 comes into contact with the inner end surface of the large-diameter tube portion 12b of the cylindrical member 12, and the operation member 8 is regulated to the second position.

  When the head 13 of the operation member 8 is rotated in this state, the drive gear 9 provided in the gear mounting portion 16 of the operation member 8 is rotated accordingly, and the inward rotation is performed according to the rotation of the drive gear 9. The ring 6 rotates. As a result, the azimuth scale displayed on the inner ring 6 and the rotation position of the scale such as each city in the world of the world time are corrected, and the azimuth and world time can be known.

  As described above, according to the wristwatch switch device 7, the head 13 located outside the wristwatch case 1 and the cylindrical member 12 of the through hole 1 a of the wristwatch case 1 connected to the head 13 are rotated. An operation member 8 having a shaft portion 14 that is slidably inserted and protrudes inside the watch case 1, and is slidably attached to the shaft portion 14 protruding inside the watch case 1 and rotates together with the operation member 8. A driving gear 9 that rotates in a direction orthogonal to the rotation direction of the driving gear 9 when the driving gear 9 is engaged, and a driving gear 9 that is engaged with the inner rotating ring 6. By providing the position restricting portion 10 that restricts the position in the axial direction, the entire wristwatch can be reduced in size.

  That is, in this switch device 7, when the operating member 8 is slid in the axial direction in a state where the driving gear 9 is engaged with the inner rotation ring 6, the position restricting portion 10 causes the driving gear 9 to move to the axis of the operating member 8. It can be regulated not to move in the direction. For this reason, it is not necessary to provide a moving space for the drive gear 9 to move, and it is possible to reduce restrictions in the watch case 1 due to the drive gear 9 and the inner ring 6.

  Thereby, in this switch apparatus 7, size reduction of the wristwatch case 1 can be achieved and size reduction of the whole wristwatch can be achieved. For this reason, since separate parts, such as a leaf | plate spring and a ratchet spring, can be installed in the wristwatch case 1, the function which prevents the click feeling and the reverse rotation of the operation member 8 can be added to the operation member 8. FIG.

  In this case, a gear mounting portion 16 is provided on the shaft portion 14 that protrudes inside the wristwatch case 1, and the gear mounting portion 16 has a length in the axial direction substantially the same as the slide length of the operation member 8. The drive gear 9 is provided with a shaft hole 17 having the same cross-sectional shape as the gear mounting portion 16 of the shaft portion 14 at the center of rotation. Thus, even when the operating member 8 is slid in the axial direction, the drive gear 9 does not move in the axial direction together with the sliding of the operating member 8, and the state of being engaged with the inner ring 6 can be maintained. Thus, the drive gear 9 can be reliably rotated in accordance with the rotation operation of the operation member 8.

  That is, the gear mounting portion 16 of the shaft portion 14 is formed in a non-circular cross-section by forming the notch portion 16a along the axial direction on the outer circumferential surface of the round bar shape. Since the shaft hole 17 is formed in the same cross-sectional shape as the gear mounting portion 16, even if the operating member 8 is slid in the axial direction, the drive gear 9 does not move in the axial direction along with the sliding of the operating member 8. In addition, the state of meshing with the inner ring 6 can be maintained, and the drive gear 9 can be reliably rotated in accordance with the rotation operation of the operation member 8 in this state.

  The position restricting portion 10 includes a first restricting portion for restricting the position of the drive gear 9 when the operation member 8 slides toward the outside of the watch case 1, and the operation member 8 toward the inside of the watch case 1. By providing the second restricting portion for restricting the position of the drive gear 9 when sliding, the drive gear 9 can be sandwiched between the first restricting portion and the second restricting portion.

  For this reason, even if the position restricting portion 10 slides the operating member 8 in the axial direction, the position of the drive gear 9 can be restricted by the first restricting portion and the second restricting portion of the position restricting portion 10. Therefore, the drive gear 9 does not move in the axial direction along with the slide of the operation member 8, and the state where the drive gear 9 is always meshed with the inner ring 6 can be maintained.

  In this case, the first restricting portion of the position restricting portion 10 is the inner end portion 12c of the small-diameter cylindrical portion 12a of the cylindrical member 12 with which the outer surface of the drive gear 9 abuts. When sliding toward the outside, the position of the drive gear 9 can be regulated by the inner end portion 12c of the cylindrical member 12 that is the first regulating portion while the drive gear 9 is engaged with the inner ring 6.

  In this case, the retaining member 18 such as an E-ring is attached to the inner end portion 14 c of the shaft portion 14 of the operating member 8, so that the retaining member 18 can contact and separate from the inner side surface of the drive gear 9. , It is possible to prevent the drive gear 9 from slipping out of the gear mounting portion 16 of the shaft portion 14 and falling off, and to restrict the position of the operation member 8 to the first position which is the push-out position. .

  The second restricting portion of the position restricting portion 10 is a stopper portion 5b provided at the edge of the insertion port 5a of the middle frame 5, and the inner surface of the drive gear 9 comes into contact with the stopper portion 5b. When the operation member 8 slides toward the inside of the watch case 1 and the inner end portion 14c of the shaft portion 14 of the operation member 8 is inserted into the insertion port 5a of the middle frame 5 together with the retaining member 18, the middle frame The position of the drive gear 9 can be reliably and satisfactorily regulated by the five stopper portions 5b.

  Further, the switch device 7 includes a switch portion 11 that is operated by the shaft portion 14 when the operation member 8 slides toward the inside of the watch case 1 inside the watch case 1. When the member 8 slides toward the outside of the watch case 1, the switch unit 11 is turned off, the watch mode can be switched to the normal watch mode, and the operation member 8 faces the inside of the watch case 1. When the user slides, the switch unit 11 is turned on, and the timepiece mode can be switched from the normal timepiece mode to another mode, for example, the azimuth mode or the world time mode.

  Therefore, in a state where the drive gear 9 is engaged with the inner rotation ring 6, the operation member 8 is pulled out to the outside of the watch case 1, and in this state, the head 13 of the operation member 8 is rotated and the inner rotation ring is operated. Even when 6 rotates, the normal timepiece mode can be maintained by the switch unit 11. Further, when the operation member 8 is pushed toward the inside of the wristwatch case 1 and the head 13 of the operation member 8 is rotated to rotate the inner ring 6, the bearing function, the world time function, etc. Other functions can be performed.

  Further, the switch device 7 includes a spring member 20 that urges the operation member 8 toward the outside of the wristwatch case 1, so that the operation member 8 as shown in FIG. Can be pushed out of the watch case 1. For this reason, normally, the normal clock mode can be maintained by turning off the switch unit 11.
