[0014] As shown in Fig. 2, the clock module 6 includes a housing 7. This housing 7 is formed in a substantially disc shape by a synthetic resin such as polycarbonate (PC), polyimide (PI), polyacetal (POM), or polyamide (PA). Inside this housing 7, as shown in Figs. 2 and 3, a first and a second movement 8, 9 which are mechanism parts, a display device 10, and a plurality (two in this embodiment) of button-type batteries 11 are arranged in parallel respectively.
[0015] That is, as shown in Figs. 2 and 3, in this housing 7, there are provided a first and a second movement housing parts 7a, 7b for housing the first and the second movements 8, 9 respectively, a display housing part 7c for housing the display device 10, and a plurality of battery housing parts 7d for housing the plurality of batteries 11 respectively.
[0016] Also, as shown in Fig. 2, a dial 12 is arranged on the upper surface of this housing 7. On the lower surface of this housing 7, a circuit board 13 which is a substrate is pressed and attached by a substrate pressing plate 15 which is a presser plate via an insulating sheet 14. That is, the substrate pressing plate 15 is a thin metal plate such as stainless steel, and is provided with a plurality of hook parts 15a extending upward from the outer peripheral part of the substrate pressing plate 15 toward the outer peripheral surface of the housing 7.
[0017] That is, as shown in Fig. 2, when the substrate pressing plate 15 is arranged via the insulating sheet 14 below the circuit board 13, it is configured such that a plurality of hook parts 15a provided on the outer peripheral part of the substrate pressing plate 15 are arranged on the outer peripheral surface of the housing 7. Thereby, the substrate pressing plate 15 is configured to press and attach the circuit board 13 to the lower surface of the housing 7 by the plurality of hook parts 15a being respectively locked to a plurality of locking protrusions 7e provided on the outer peripheral surface of the housing 7.
[0018] Incidentally, as shown in FIGS. 2 and 3, the first movement 8 is a main functional unit that indicates time. This first movement 8 rotates a pointer shaft 8a that protrudes above the dial 12 through a first through hole 12a located at the center of the dial 12, and moves hands 8b such as a second hand, a minute hand, and an hour hand provided on this pointer shaft 8a above the dial 12 to indicate time. In this first movement 8, the pointer shaft 8a is arranged at the center of the housing 7.
[0019] As shown in FIGS. 1 and 3, the second movement 9 is a sub-functional unit that indicates a sub-function. This second movement 9 rotates a sub-pointer shaft 9a that protrudes above the dial 12 through a second through hole (not shown) located on the 9 o'clock side of the dial 12, and moves a substantially disk-shaped sub-pointer 9b (see FIG. 1) provided on this sub-pointer shaft 9a above the dial 12 to indicate the sub-function. In this second movement 9, the sub-pointer shaft 9a is arranged on the 9 o'clock side of the dial 12.
[0020] In this case, as shown in FIGS. 2 and 3, mounting plates 16 are provided on the upper surfaces of the first and second movements 8 and 9. This mounting plate 16 is attached to the housing 7 by a fastening member 16a. Thereby, the first and second movements 8 and 9 are attached to the housing 7 by the fastening member 16a in a state where the first and second movements 8 and 9 are respectively housed in the first and second movement storage portions 7a and 7b of the housing 7, with the mounting plate 16 to which the first and second movements 8 and 9 are attached.
[0021] That is, as shown in FIG. 2, the fastening member 16a includes a screw 16b and a screw pipe 16c embedded in the housing 7. Thereby, the fastening member 16a is configured to attach the mounting plate 16 together with the first and second movements 8 and 9 to the housing 7 by screwing the screw 16b into the screw pipe 16c in the housing 7 from above the mounting plate 16 and tightening it.
[0022] As shown in FIGS. 2 and 3, the display device 10 includes a liquid crystal display panel 17 and a backlight unit 18. The liquid crystal display panel 17 electro-optically displays various types of information necessary for clock functions such as time, date, and day of the week, and is formed in a substantially rectangular shape with a horizontal length. This liquid crystal display panel 17 is disposed obliquely between the 3 o'clock side and the 6 o'clock side within the display housing portion 7c of the housing 7.
[0023] That is, as shown in FIG. 2, when the liquid crystal display panel 17 is housed within the display housing portion 7c of the housing 7, the outer peripheral edge portion on the upper surface of the liquid crystal display panel 17 is configured to be pressed against the flange portion 7f provided at the upper portion of the display housing portion 7c from below. In this case, as shown in FIGS. 1 to 3, the dial 12 is provided with a plurality of display window portions 12c corresponding to a plurality of display regions of the liquid crystal display panel 17.
[0024] That is, as shown in FIGS. 1 to 3, the plurality of display window portions 12c are provided on the dial 12 corresponding to a plurality of display regions of the liquid crystal display panel 17 located on the 3 o'clock side and the 6 o'clock side of the dial 12, respectively. Thereby, the liquid crystal display panel 17 displays different information in the display region on the 3 o'clock side and the display region on the 6 o'clock side, and the information displayed through the plurality of display window portions 12c of the dial 12 is configured to be visible from above.
[0025] Further, as shown in FIG. 2, the liquid crystal display panel 17 is housed within the display housing portion 7c of the housing 7, and in a state where the outer peripheral edge portion on the upper surface of the liquid crystal display panel 17 is pressed against the flange portion 7f provided at the upper portion of the display housing portion 7c from below, the outer side portion of the liquid crystal display panel 17 is supported by the interconnector 20 and a support member (not shown). In this case, the liquid crystal display panel 17 is electrically connected to the electrode terminal 13a (see FIG. 4) provided on the circuit board 13 by the interconnector 20.
[0026] The backlight unit 18 of the display device 10 is for illuminating the lower surface side of the liquid crystal display panel 17 as shown in FIG. 2. This backlight unit 18 includes a light guide plate 18a disposed on the lower side of the liquid crystal display panel 17, a diffusion plate 18b provided on the lower surface of this light guide plate 18a, and a light emitting element 18c provided on one side portion on the lower side of this diffusion plate 18b.
[0027] Accordingly, as shown in FIG. 2, the backlight unit 18 is configured to diffuse the light emitted by the light emitting element 18c with the diffusion plate 18b and make it incident on the light guide plate 18a, guide the incident light with the light guide plate 18a, and irradiate the lower surface of the liquid crystal display panel 17 with this guided light almost uniformly. In this case, integrated elements 13b such as an LSI (large scale integrated circuit) shown in FIG. 4 are disposed on the circuit board 13 located below the diffusion plate 18b.
[0028] On the other hand, as shown in FIGS. 2 and 3, the plurality of batteries 11 are configured to be respectively housed and disposed in the respective battery housing portions 7d provided at two locations on the 1 o'clock side and the 11 o'clock side in the housing 7. That is, the centers of these plurality of batteries 11 are arranged at a predetermined interval, for example, an opening angle of about 60°, on concentric circles centered on the pointer shaft 8a of the first movement 8, which is the center portion of the dial 12, that is, the predetermined portion of the housing 7.
[0029] That is, as shown in FIG. 3, the plurality of batteries 11 are arranged in a line-symmetrical state with respect to a straight line passing through the center portion of the housing 7 and the midpoint between the plurality of batteries 11. Since these plurality of batteries 11 are disposed in the respective battery housing portions 7d provided at two locations on the 1 o'clock side and the 11 o'clock side in the housing 7, they are arranged on concentric circles with an opening angle of about 60° centered on the center portion of the housing 7. As a result, in the clock module 6, since the center of gravity positions are dispersed by the plurality of batteries 11, it is easy to achieve weight balance.
[0030] In this case, as shown in FIG. 3(b), the first movement 8 is disposed near the central portion of the housing 7 in a state corresponding to between a plurality of batteries 11. That is, the first movement storage portion 7a near the central portion of the housing 7 is provided so as to penetrate between the plurality of batteries 11 from the central portion of the housing 7. For this reason, the first movement 8 is disposed in the housing 7 in a state where a part thereof penetrates between the plurality of batteries 11.
[0031] As a result, as shown in FIG. 3(b), in the clock module 6, the center of gravity is dispersed by the plurality of batteries 11 and the first movement 8, so that it is easy to achieve weight balance. Further, in this clock module 6, the center of gravity is also dispersed by the first movement 8 and the second movement 9. Therefore, the center of gravity is favorably dispersed by the plurality of batteries 11 and the first and second movements 8 and 9, and thus the clock module 6 is configured to be even easier to achieve weight balance.
[0032] Further, as shown in FIGS. 2 and 3, the plurality of batteries 11 are individually pressed into the respective battery storage portions 7d of the housing 7 by a plurality of battery pressing plates 22. That is, each of the plurality of battery pressing plates 22 is integrally formed with the substrate pressing plate 15 and is formed in a substantially disk shape corresponding to the battery storage portion 7d.
[0033] That is, as shown in FIGS. 2 and 3, for each of the plurality of battery pressing plates 22, a part of the outer peripheral portion of the disk shape is connected to the substrate pressing plate 15, and an engaging portion 22a is provided at the other part of the outer peripheral portion located diagonally with respect to this part. Thereby, each of the plurality of battery pressing plates 22 is configured such that the engaging portion 22a is detachably locked to the protruding portion 7g of the housing 7 located on the outer peripheral portion of the battery storage portion 7d to press the battery 11 into the battery storage portion 7d.
[0034] On the other hand, as shown in FIG. 4, the circuit board 13 is formed in a disc shape that is approximately the same size as the housing 7, and a plurality of openings 13c through which the batteries 11 are inserted from below are provided at two locations, the 1 o'clock side and the 11 o'clock side, corresponding to the plurality of battery storage portions 7d of the housing 7, respectively. On the upper surface of this circuit board 13, various electronic components such as a crystal oscillator 13d, a plurality of capacitors 13e, and a plurality of choke coils 13f are provided in addition to the electrode terminals 13a and the integrated element 13b.
[0035] As a result, as shown in FIGS. 2 and 3, the clock module 6 is formed with a thin overall thickness. That is, the housing 7 of this clock module 6 has a thickness of about 2 mm, and each of the plurality of batteries 11 has a thickness of about 2.6 mm. Thereby, the clock module 6 has a thickness of about 3 mm from the upper surface of the housing 7 to the board pressing plate 15, and the thickness at the location corresponding to the battery 11 is about 3.5 mm. For this reason, this clock module 6 is formed about 2 mm thinner than the thickness of a normal clock module (5 - 6 mm).
[0036] Further, as shown in FIGS. 2 and 3, in this clock module 6, the center of gravity positions are dispersed and the weight balance is achieved by the plurality of batteries 11 arranged in parallel in the housing 7 and the first and second movements 8 and 9. Thereby, when the wristwatch case 1 receives an impact in a state where the clock module 6 is incorporated in the wristwatch case 1, the impact resistance is enhanced even though the clock module 6 is thinned.
[0037] By the way, among the plurality of switch devices 3, the switch devices 3 on the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side are side switches as shown in FIG. 1, respectively, and the switch device 3 on the 6 o'clock side is an upper surface switch. This switch device 3 on the 6 o'clock side, which is the upper surface switch, includes a contact spring 23, which is a contact member provided on the board pressing plate 15 of the clock module 6, a button portion 24 that presses the contact spring 23 toward the outer peripheral surface side of the circuit board 13, and a contact portion 25 with which the contact spring 23 can contact and separate, as shown in FIGS. 5 and 6.
[0038] As shown in FIGS. 5 to 7, the contact spring 23 is a metal leaf spring provided upright on the outer peripheral portion of the substrate pressing plate 15. This contact spring 23 rises from the outer peripheral portion of the substrate pressing plate 15 toward the outer peripheral surface of the housing 7 via the outer peripheral surface of the circuit board 13, and is provided on the outer peripheral portion of the substrate pressing plate 15 in a state of extending along the outer peripheral direction of each of the outer peripheral surfaces of the circuit board 13 and the housing 7.
[0039] That is, as shown in FIGS. 5 to 7, this contact spring 23 includes a fulcrum portion 26 fixed to the circuit board 13, and a movable portion 27 extending along the outer peripheral direction on the outer peripheral surface of the housing 7 from this fulcrum portion 26. The fulcrum portion 26 is provided upright on the outer peripheral portion of the substrate pressing plate 15, and protrudes upward from the outer peripheral surface of the circuit board 13 toward the outer peripheral surface of the housing 7.
[0040] As shown in FIG. 7, the movable portion 27 extends along the outer peripheral direction on the outer peripheral surface of the housing 7 from the upper portion of the fulcrum portion 26 protruding from the outer peripheral surface of the housing 7, and the extended tip portion is configured to be in contact with and separable from the contact portion 25. Thereby, the contact spring 23 is configured such that the movable portion 27 bends and deforms in the contact and separation direction with respect to the outer peripheral surface of the housing 7 with the fulcrum portion 26 as a fulcrum.
[0041] As shown in FIGS. 5 to 7, the contact portion 25 is a terminal plate with which the movable portion 27 of the contact spring 23 is in contact with and separable from, and is provided on the outer peripheral surface of the housing 7 and is electrically connected to the circuit board 13. That is, this contact portion 25 is provided at a position separated from the fulcrum portion 26 of the contact spring 23 along the outer peripheral direction on the outer peripheral surface of the housing 7. Further, the lower end portion 25a of this contact portion 25 is disposed on the lower surface of the housing 7, and this lower end portion 25a is in contact with an electrode (not shown) of the circuit board 13 and is electrically connected to the circuit board 13.
[0042] As shown in FIGS. 5 and 6, the button portion 24 includes an operation head 28, an operation shaft 29, and a spring member 30. The operation head 28 is provided at the outer end portion of the operation shaft 29 and is disposed in a vertically inclined manner within a storage recess 1e provided in the main body case 1a of the wristwatch case 1. The operation shaft 29 is slidably inserted through a shaft through-hole 1f provided obliquely upward and downward in the main body case 1a via a plurality of waterproof rings 29a. Further, a retaining member 29b such as an E-ring is attached to the inner end portion of the operation shaft 29 protruding into the main body case 1a.
[0043] In this case, as shown in FIGS. 5 and 6, when the operation shaft 29 is inserted into the shaft through-hole 1f provided in the main body case 1a, it is disposed at a predetermined angle obliquely upward with respect to the movable portion 27 of the contact spring 23. That is, the inclination angle θ of this operation shaft 29 is in the range of 15° to 35°, preferably about 25°. For this reason, the operation head 28 is provided at the outer end portion of the operation shaft 29 perpendicular to the central axis and is disposed in a vertically inclined manner with respect to the wristwatch case 1 at an angle that is easy to operate the button.
[0044] As shown in FIGS. 5 and 6, the spring member 30 is a coil spring and is disposed on the outer periphery of the operation shaft 29 and between the operation head 28 and the bottom portion within the storage recess 1e of the main body case 1a. For this reason, this spring member 30 is configured to bias the operation head 28 in a direction of pushing it out toward the outside of the wristwatch case 1 by its spring force.
[0045] As a result, as shown in FIGS. 5 to 7, in the normal state, the switch device 3 on the 6 o'clock side is in a state where the operation shaft 29 of the button portion 24 is elastically in contact with the movable portion 27 of the contact spring 23, and the operation head 28 is biased in a direction of being pushed out obliquely upward by the spring force of the spring member 30. For this reason, this switch device 3 is configured such that when the operation head 28 is pushed out in a state of being inclined to the outside of the wristwatch case 1 and the inner end portion of the operation shaft 29 is elastically in contact with the movable portion 27 of the contact spring 23, the movable portion 27 moves away from the contact portion 25 and enters an off state.
[0046] Further, as shown in FIGS. 6 and 7, in this switch device 3, when the operation head 28 of the button portion 24 is pushed obliquely upward against the spring force of the spring member 30 and the inner end portion of the operation shaft 29 presses the contact spring 23, the movable portion 27 is configured to bend and deform toward the outer peripheral surface of the housing 7 with the fulcrum portion 26 as a fulcrum. Thereby, when the movable portion 27 of this switch device 3 bends and deforms toward the outer peripheral surface of the housing 7, the contact portion 27b of the movable portion 27 contacts the contact portion 25 to be in an on state.
[0047] In this case, as shown in FIG. 7, the movable portion 27 of the contact spring 23 is provided with a meandering portion 27a that meanders in a direction orthogonal to the extending direction of the movable portion 27, that is, in the respective thickness directions of the circuit board 13 and the housing 7 (the vertical direction in FIG. 7). This meandering portion 27a is for increasing the length of the movable portion 27 from the contact portion 27b that contacts the contact portion 25 to the fulcrum portion 26 when the contact spring 23 is pressed by the operation shaft 29 of the button portion 24, and is provided to be curved in a U shape when extending in the outer peripheral direction on the outer peripheral surface of the housing 7 from the upper end portion of the fulcrum portion 26.
[0048] That is, as shown in FIG. 7, when the meandering portion 27a extends in the outer peripheral direction on the outer peripheral surface of the housing 7 from the upper portion of the fulcrum portion 26, it extends downward from this extending end portion, the lower portion extending downward is curved in an arc shape, and by extending upward from this curved end portion, it is formed in a U shape.
[0049] In this case, as shown in FIGS. 5 to 7, the contact portion 27b is provided to be inclined toward the outer peripheral surface of the housing 7, that is, the contact portion 25, on the upper portion of the meandering portion 27a that extends upward. Thereby, when the contact spring 23 is pressed by the operation shaft 29 and the movable portion 27 bends and deforms, the contact portion 27b is elastically contacted with the contact portion 25, so that it is configured to be easily contacted with the contact portion 25.
[0050] Therefore, as shown in FIG. 7, even if the straight-line distance from the fulcrum portion 26 to the contact portion 27b of the meandering portion 27a is short, by increasing the length of the movable portion 27 from the fulcrum portion 26 to the contact portion 27b, when the movable portion 27 is pressed by the operation shaft 29 and bends and deforms with the fulcrum portion 26 as a fulcrum, the movable portion 27 is made easier to bend and deform, and a large load is not applied to the fulcrum portion 26.
[0051] Further, as shown in FIGS. 5 to 7, the contact spring 23 is provided with a pressing portion 27c pressed by the operation shaft 29 on each upper portion of the fulcrum portion 26 and the movable portion 27. This pressing portion 27c is provided so as to be inclined in a direction substantially orthogonal to the central axis of the operation shaft 29. Thereby, even if the operation shaft 29 of the button portion 24 is inclined at a predetermined angle with respect to the outer peripheral surface of the circuit board 13, the inner end portion of the operation shaft 29 is configured to be pressed from a direction substantially orthogonal.
[0052] Next, the operation of such a wristwatch will be described. When assembling this wristwatch, first, the wristwatch case 1 is assembled. At this time, the cut portion 6a and the watch glass 4 are fitted into the upper opening of the main body case 1a, and the outer case 1b is attached to the upper portion and the outer periphery of the main body case 1a by a plurality of screws 1d to cover these. Thereby, the wristwatch case 1 is assembled.
[0053] In this state, a plurality of switch devices 3 are respectively attached to the side portions of the wristwatch case 1 at the 2 o'clock side, 4 o'clock side, 6 o'clock side, 8 o'clock side, and 10 o'clock side. In this case, when attaching the switch device 3 on the 6 o'clock side, which is the upper surface switch, to the wristwatch case 1, first, a plurality of waterproof rings 29a are attached to the outer peripheral surface of the operation shaft 29.
[0054] In this state, a spring member 30 is disposed on the outer periphery of the operation shaft 29 of the button portion 24, the operation shaft 29 is inserted into the shaft through hole 1f of the main body case 1a, and the operation head portion 28 is disposed in the storage recess 1e on the outer side of the main body case 1a. At this time, a retaining member 29b is attached to the inner end portion of the operation shaft 29 protruding into the wristwatch case 1. Thereby, the button portion 24 of the switch device 3 on the 6 o'clock side is attached to the wristwatch case 1.
[0055] Then, the timepiece module 6 is assembled in the wristwatch case 1. At this time, the timepiece module 6 is assembled in advance. In this case, the first and second movements 8 and 9 are disposed in the first and second movement storage portions 7a and 7b of the housing 7, and in this state, the mounting plates 16 provided on the first and second movements 8 and 9 are attached to the housing 7 by fastening members 16a. Thereby, the first and second movements 8 and 9 are attached to the housing 7.
[0056] Also, at this time, the display device 10 is disposed in the display storage portion 7c of the housing 7. That is, the liquid crystal display panel 17 is inserted into the display storage portion 7c from below, and the interconnector 20 and the backlight portion 18 are disposed below the liquid crystal display panel 17. In this state, the circuit board 13 is disposed on the lower surface of the housing 7, and the board pressing plate 15 is disposed via the insulating sheet 14 below the circuit board 13 and attached to the housing 7.
[0057] At this time, a plurality of hook portions 15a provided on the outer peripheral portion of the board pressing plate 15 are respectively locked to a plurality of locking protrusions 7e provided on the outer peripheral surface of the housing 7. Thereby, the circuit board 13 is assembled to the lower surface of the housing 7, and the display device 10 housed in the display storage portion 7c of the housing 7 is pressed by the circuit board 13 in a state of being electrically connected to the circuit board 13. At this time, the movable portion 27 of the contact spring 23 of the switch device 3 on the 6 o'clock side is correspondingly disposed in a state of being able to contact and separate from the contact portion 25 provided on the outer peripheral surface of the housing 7.
[0058] Also, in this state, a plurality of batteries 11 are respectively arranged in a plurality of battery storage portions 7d of the housing 7. At this time, a plurality of battery pressing plates 22 connected to the board pressing plate 15 are respectively lifted. In this state, the plurality of batteries 11 are respectively stored in the plurality of battery storage portions 7d of the housing 7 through a plurality of openings 13c provided in the circuit board 13.
[0059] Then, the plurality of battery pressing plates 22 are respectively pressed against the plurality of batteries 11, and each engaging portion 22a of the plurality of battery pressing plates 22 is respectively locked to each protruding portion 7g of the housing 7. Then, the plurality of batteries 11 are respectively individually pressed against the plurality of battery storage portions 7d by the plurality of battery pressing plates 22. Thereby, the plurality of batteries 11 are incorporated into the housing 7.
[0060] In this case, the center of gravity position of the clock module 6 is dispersed by the plurality of batteries 11 and the first and second movements 8 and 9, and the weight balance of the entire clock module 6 is achieved. That is, the plurality of batteries 11 are arranged on concentric circles centered on the pointer shaft 8a of the first movement 8, the center of each battery 11 being the center of the dial 12, that is, the center of the housing 7, with a predetermined interval, for example, an opening angle of about 60°.
[0061] That is, the plurality of batteries 11 are arranged in the battery storage portions 7d provided at two locations on the 1 o'clock side and the 11 o'clock side in the housing 7, and are arranged on concentric circles with an opening angle of about 60° centered on the center of the housing 7. Thereby, since the center of gravity position of the clock module 6 is dispersed by the plurality of batteries 11, it is easier to achieve a weight balance.
[0062] In this case, the first movement storage part 7a provided near the central part of the housing 7 is provided so as to penetrate between a plurality of batteries 11 from the central part of the housing 7. For this reason, the first movement 8 is arranged in the housing 7 in a state where a part of it penetrates between the plurality of batteries 11. Thereby, in the clock module 6, the center of gravity position is further dispersed by the plurality of batteries 11 and the first movement 8, and also by the first movement 8 and the second movement 9, and the weight balance of the entire clock module 6 is achieved.
[0063] Then, this clock module 6 is assembled into the wristwatch case 1. At this time, first, the dial 12 is arranged on the upper surface of the housing 7. In this state, the pointer 8b is attached to the pointer shaft 8a of the first movement 8 that protrudes upward through the first through hole 12a of the dial 12. Also, at this time, the subsidiary hand 9b is attached to the subsidiary hand shaft 9a of the second movement 9 that protrudes upward through the second through hole (not shown) of the dial 12.
[0064] In this state, among the plurality of switch devices 3 provided on each side part of the 2 o'clock side, 4 o'clock side, 6 o'clock side, 8 o'clock side, and 10 o'clock side of the wristwatch case 1, the pressing part 27c of the contact spring 23 assembled to the clock module 6 is made to correspond to the operation shaft 29 of the button part 24 of the switch device 3 on the 6 o'clock side, which is the upper surface switch. At this time, the pressing part 27c of the contact spring 23 is elastically contacted with the inner end part of the operation shaft 29 of the button part 24.
[0065] Thereby, the contact spring 23 is arranged in a state where the contact part 27b of the movable part 27 is separated from the contact part 25 provided on the outer peripheral surface of the housing 7 of the clock module 6 by the operation shaft 29 of the button part 24. Thereby, the switch device 3 on the 6 o'clock side, which is the upper surface switch, is incorporated into the wristwatch case 1 in the off state. After that, the back cover 5 is attached to the lower part of the wristwatch case 1, that is, the lower part of the main body case 1a. Thereby, the wristwatch is assembled.
[0066] Next, the case of using the wristwatch assembled in this way will be described. In the normal state, the time indicated by the hands 8b of the first movement 8, the indication of the sub-function indicated by the sub-hand 9b of the second movement 9, and the information displayed in the plurality of display areas on the liquid crystal display panel 17 of the display device 10 corresponding to the plurality of display window portions 12c of the dial 12 are visible from the outside of the watch case 1 through the watch glass 4.
[0067] In this state, when the watch case 1 is impacted from the outside, the impact is transmitted to the watch module 6 inside the watch case 1. At this time, since the weight balance of the watch module 6 is taken, the impact is mitigated, and the breakage of the watch module 6 is significantly reduced. Therefore, even if the watch module 6 is thinned, its shock resistance is enhanced.
[0068] That is, in this watch module 6, the center of gravity positions of the plurality of batteries 11 incorporated in the housing 7 and the first and second movements 8 and 9 are well dispersed, and the weight balance is taken. For this reason, the impact transmitted to the watch module 6 when the watch case 1 is received is mitigated, so even if the watch module 6 is thinned, its shock resistance is enhanced.
[0069] In this case, the plurality of batteries 11 are arranged at a predetermined interval, for example, with an opening angle of about 60°, on concentric circles centered on the pointer shaft 8a of the first movement 8 whose center of each battery 11 is located at the center of the dial 12, that is, the center of the housing 7. As a result, the center of gravity positions of the plurality of batteries 11 are dispersed, and it becomes easier to take the weight balance of the watch module 6.
[0070] Also, the first movement 8 is arranged near the central portion of the housing 7 in a state corresponding to between the plurality of batteries 11, and a part of the first movement 8 is arranged so as to penetrate between the plurality of batteries 11 from the center of the housing 7. As a result, the center of gravity positions of the plurality of batteries 11 and the first movement 8 are further dispersed, and it becomes easier to take the weight balance of the watch module.
[0071] Furthermore, since the center of gravity of this clock module 6 is also dispersed by the first movement 8 and the second movement 9, the center of gravity is well dispersed by these plurality of batteries 11 and the first and second movements 8 and 9, making it even easier to achieve a better weight balance of the clock module 6.
[0072] As a result, in this wristwatch, even if the wristwatch case 1 is impacted from the outside and the impact is transmitted to the clock module 6 inside the wristwatch case 1, the center of gravity is dispersed by the plurality of batteries 11 incorporated in the housing 7 and the first and second movements 8 and 9, and a good weight balance of the clock module 6 is achieved. Therefore, the impact is mitigated and the breakage of the clock module 6 is significantly reduced.
[0073] Also, in this wristwatch, even if the wristwatch case 1 is impacted from the outside and the impact is transmitted to the clock module 6 inside the wristwatch case 1, since the plurality of batteries 11 are individually pressed into the respective battery storage portions 7d of the housing 7 by the plurality of battery pressing plates 22, the impact transmitted to the clock module 6 is dispersed among the plurality of batteries 11. As a result, the plurality of batteries 11 can be prevented from falling off due to the impact transmitted to the clock module 6.
[0074] Next, the case of operating the switch device 3 on the 6 o'clock side, which is the upper surface switch, among the plurality of switch devices 3 of this wristwatch will be described. In this case, when in the normal state, the inner end portion of the operating shaft 29 of the button portion 24 is elastically in contact with the pressing portion 27c of the contact spring 23, and the operating head 28 is pushed obliquely upward by the spring force of the spring member 30. Therefore, in this switch device 3, the contact portion 27b of the movable portion 27 of the contact spring 23 is separated from the contact portion 25 and is in an off state.
[0075] In this state, when the operation head 28 of the buckle portion 24 is pressed obliquely upward against the spring force of the spring member 30, the inner end portion of the operation shaft 29 presses the pressing portion 27c of the movable portion 27. At this time, since the operation shaft 29 of the buckle portion 24 is inclined at a predetermined angle θ with respect to the wristwatch case 1, the operation head 28 of the buckle portion 24 is inclined with respect to the wristwatch case 1. Therefore, since the operation head 28 can be pressed obliquely upward, the buckle portion 24 can be easily and favorably operated.
[0076] Also, at this time, since the pressing portion 27c provided on the contact spring 23 is inclined in a direction substantially orthogonal to the central axis of the operation shaft 29, even if the operation shaft 29 is inclined at a predetermined angle θ with respect to the wristwatch case 1, the inner end portion of the operation shaft 29 is pressed against the pressing portion 27c of the contact spring 23 from a direction substantially orthogonal thereto. Therefore, the pressing portion 27c is reliably and favorably pressed by the operation shaft 29.
[0077] Thus, when the inner end portion of the operation shaft 29 presses the pressing portion 27c of the movable portion 27, the movable portion 27 of the contact spring 23 deflects and deforms toward the outer peripheral surface of the housing 7 with the fulcrum portion 26 as a fulcrum. Thereby, the contact portion 27b of the movable portion 27 elastically contacts the contact portion 25. That is, since the contact portion 27b is provided to be inclined toward the contact portion 25, it elastically contacts when contacting the contact portion 25. Thereby, in this switch device 3, the contact portion 27b of the movable portion 27 elastically contacts the contact portion 25 and turns on.
[0078] At this time, since the movable portion 27 is provided with a meandering portion 27a that meanders in a direction orthogonal to its extending direction, that is, in the respective thickness directions (vertical direction in FIG. 7) of the circuit board 13 and the housing 7, the length of the movable portion 27 from the contact portion 27b to the fulcrum portion 26 is increased by this meandering portion 27a. Thereby, the movable portion 27 becomes more easily deflectable with the fulcrum portion 26 as a fulcrum.
[0079] That is, even if the straight-line distance from the fulcrum portion 26 to the contact portion 27b of this meandering portion 27a is short, by increasing the length of the movable portion 27 from the fulcrum portion 26 to the contact portion 27b, the entire switch device 3 can be made more compact. When the pressing portion 27c is pressed by the operation shaft 29, the movable portion 27 is easily bent and deformed with the fulcrum portion 26 as the fulcrum, preventing a large load from being applied to the fulcrum portion 26.
[0080] In this case, the contact spring 23 is arranged corresponding to the outer peripheral surface of the housing 7. On the outer peripheral surface of the housing 7, the contact portion 25 is provided so as to be electrically connected to the circuit board 13. Thus, even if the length (thickness) from the lower surface of the circuit board 13 to the upper surface of the housing 7 is short (thin), the contact spring 23 and the contact portion 25 are surely and favorably arranged corresponding to the outer peripheral surface sides of the circuit board 13 and the housing 7.
[0081] Therefore, in this switch device 3, the length (thickness) from the lower surface of the circuit board 13 to the upper surface of the housing 7 becomes short (thin), and the thickness of the entire clock module 6 becomes thin. Thus, even if the thickness of the entire clock module 6 is made thin, the contact spring 23 and the contact portion 25 can be provided compactly corresponding to the outer peripheral surfaces of the circuit board 13 and the housing 7.
[0082] Further, the contact spring 23 is integrally provided upright on the outer peripheral portion of the board pressing plate 15 arranged on the lower surface of the circuit board 13, so that the contact spring 23 is surely and favorably arranged corresponding to the outer peripheral surfaces of the circuit board 13 and the housing 7. Also, since the contact spring 23 is integrally formed with the board pressing plate 15, even if the contact spring 23 is provided, good productivity can be achieved and the number of parts can be reduced.
[0083] Thus, according to the switch device 3 of this wristwatch, it includes a contact spring 23 arranged along the outer peripheral direction on the outer peripheral surface side of the circuit board 13, and a contact portion 25 fixed to the circuit board 13 and in contact with the contact spring 23 in a separable manner. The contact spring 23 includes a fulcrum portion 26 fixed to the circuit board 13 and protruding toward the upper surface side of the circuit board 13, and a movable portion 27 having a meandering portion 27a extending from the fulcrum portion 26 in the outer peripheral direction of the outer peripheral surface of the circuit board 13. By this, the miniaturization of the entire device can be achieved, and the breakage of the contact spring 23 can be prevented and it can be bent and deformed well.
[0084] That is, in this switch device 3, due to the meandering portion 27a provided on the movable portion 27 of the contact spring 23, even if the linear distance from the fulcrum portion 26 to the tip of the movable portion 27 is short, the length of the movable portion 27 from the fulcrum portion 26 to the tip of the movable portion 27 can be increased. Therefore, the miniaturization of the entire device can be achieved, and when the contact spring 23 is pressed by the operation shaft 29, the movable portion 27 can be easily bent and deformed with the fulcrum portion 26 as the fulcrum. Thereby, a large load can be prevented from being applied to the fulcrum portion 26, so that the breakage of the contact spring 23 can be prevented and it can be bent and deformed well.
[0085] In this case, in this switch device 3, the meandering portion 27a meanders in a direction perpendicular to the extension direction of the movable portion 27, that is, in the thickness direction of the circuit board 13, and a contact portion 27b that is in contact with the contact portion 25 in a separable manner is provided at the tip of the meandering meandering portion 27a. Thus, the length of the movable portion 27 from the fulcrum portion 26 to the contact portion 27b can be surely and favorably increased by the meandering portion 27a. Therefore, even if the linear distance from the fulcrum portion 26 to the contact portion 27b is short, the movable portion 27 can be easily bent and deformed with the fulcrum portion 26 as the fulcrum by the meandering portion 27a, and thereby a large load can be prevented from being applied to the fulcrum portion 26.
[0086] Further, this switch device 3 includes a housing 7 disposed on the upper surface side of the circuit board 13. A contact spring 23 is disposed corresponding to the outer peripheral surface of the housing 7, and a contact portion 25 is provided on the outer peripheral surface of the housing 7 so as to be electrically connected to the circuit board 13. Thus, even if the length (thickness) from the lower surface of the circuit board 13 to the upper surface of the housing 7 is short (thin), the contact spring 23 and the contact portion 25 can be surely and favorably arranged corresponding to the outer peripheral surfaces of the circuit board 13 and the housing 7.
[0087] Therefore, in this switch device 3, the length (thickness) from the lower surface of the circuit board 13 to the upper surface of the housing 7 can be shortened (thinned), and the thickness of the entire clock module 6 can be reduced. Also, even if the thickness of the entire clock module 6 is reduced, the contact spring 23 and the contact portion 25 can be provided compactly corresponding to the outer peripheral surfaces of the circuit board 13 and the housing 7, thereby reducing the size of the entire switch device 3.
[0088] Further, in this switch device 3, the contact spring 23 is integrally provided so as to stand on the outer peripheral portion of a board pressing plate 15 disposed on the lower surface of the circuit board 13. Thus, the contact spring 23 can be surely and favorably arranged corresponding to the outer peripheral surfaces of the circuit board 13 and the housing 7. Also, by integrally forming the contact spring 23 with the board pressing plate 15, even if the contact spring 23 is provided, productivity is good and the number of components can be reduced.
[0089] Further, this switch device 3 includes a button portion 24 that presses the contact spring 23 toward the outer peripheral surface side of the circuit board 13. Since an operation shaft 29, which is the button shaft of the button portion 24, is inclined at a predetermined angle with respect to the outer peripheral surface of the circuit board 13, the operation shaft 29 can be inclined at a predetermined angle θ with respect to the wristwatch case 1. Thus, the operation head 28 of the button portion 24 can be inclined with respect to the wristwatch case 1, so that the operability of the button portion 24 can be improved.
[0090] That is, in this switch device 3, by tilting the operation shaft 29 at a predetermined angle θ with respect to the watch case 1, the operation head 28 of the buckle portion 24 can be tilted in the vertical direction with respect to the watch case 1. Therefore, when pressing the buckle portion 24, the operation head 28 can be pressed from obliquely above, so that the operation head 28 can be easily and favorably pressed, thereby improving the operability of the buckle portion 24.
[0091] Furthermore, in this switch device 3, the pressing portion 27c pressed by the operation shaft 29 which is the buckle shaft of the buckle portion 24 is provided on the contact spring 23 so as to be inclined in a direction substantially orthogonal to the operation shaft 29. Thus, even if the operation shaft 29 of the buckle portion 24 is inclined at a predetermined angle with respect to the outer peripheral surface of the circuit board 13, the inner end portion of the operation shaft 29 can be pressed against the pressing portion 27c of the contact spring 23 from a direction substantially orthogonal thereto. Therefore, the pressing portion 27c can be surely and favorably pressed by the operation shaft 29.
[0092] Also, in this switch device 3, the contact portion 27b is provided on the meandering portion 27a of the movable portion 27 of the contact spring 23 so as to be inclined toward the contact portion 25. Thus, when the pressing portion 27c of the contact spring 23 is pressed by the operation shaft 29 of the buckle portion 24 and the movable portion 27 of the contact spring 23 is bent and deformed, the contact portion 27b of the meandering portion 27a can be elastically brought into contact with the contact portion 25.
[0093] In the above-described embodiment, the case where a plurality of batteries 11 are arranged at two positions on the 1 o'clock side and the 11 o'clock side of the housing 7 with an opening angle of about 60° has been described. However, the present invention is not limited to this, and a plurality of batteries 11 may be arranged concentrically at an angle of an opening angle of about 60° or more. Also, although the case where a plurality of batteries 11 are arranged concentrically around the center of the housing 7 has been described, the present invention is not limited to this, and they may be arranged concentrically around a predetermined portion such as a predetermined position of the housing 7 instead of the center of the housing 7.
[0094] In addition, in the above-described embodiment, the case where two batteries 11 are provided in the housing 7 has been described. However, the present invention is not limited to this, and for example, a structure in which three or more batteries 11 are provided in the housing 7 may be used.
[0095] In addition, in the above-described embodiment, the case where a U-shaped meandering portion 27a that meanders once is provided in the movable portion 27 of the contact spring 23 of the switch device 3 has been described. However, the present invention is not limited to this, and a structure in which a W-shaped meandering portion that meanders twice is provided may be used, or a structure in which a meandering portion that meanders three or more times is provided may be used.
[0096] In addition, in the above-described embodiment, the case where a meandering portion 27a that is a bent portion is provided in the movable portion 27 of the contact spring 23 of the switch device 3 has been described. However, the present invention is not limited to this, and the bent portion may be a bent portion that is bent and bent when extending in the outer circumferential direction on the outer circumferential surface of the housing 7 from the upper end portion of the fulcrum portion 26, and the bent portion may have both a curved portion and a bent portion.
[0097] In addition, the contact spring 23 of the switch device 3 may be a leaf spring having a shape bent in accordance with the shape of the outer circumference of the housing 7.
[0098] Furthermore, in the above-described embodiment, the case where it is applied to a wristwatch has been described. However, the present invention does not necessarily have to be a wristwatch, and for example, it can be applied to various timepieces such as travel watches, alarm clocks, table clocks, and wall clocks. In addition, the present invention does not necessarily have to be a timepiece, and for example, it can be widely applied to electronic devices such as mobile communication devices and portable information terminals.
