Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a watch, since the light-emitting portion is directly provided on the circuit board disposed on the lower surface of the dial, depending on the model of the watch, for example, if other members such as a solar panel are disposed between the dial and the circuit board, the height of the light-emitting portion with respect to the dial becomes low, and the light-emitting portion is disposed below the dial, so that the dial cannot be illuminated well.

[0005] Therefore, in such a watch, in order to illuminate the dial with the light-emitting portion, a special structure different for each model, such as providing a reflecting surface on a cut-off portion located above the light-emitting portion and reflecting the light of the light-emitting portion toward the upper surface of the dial by this reflecting surface, must be adopted, so there is a problem of lack of diversity.

[0006] The problem to be solved by the present invention is to provide a lighting device excellent in diversity, a module including the same, and a watch including them. [Means for solving the problem]

Mode for Carrying Out the Invention

[0010] Hereinafter, with reference to FIGS. 1 to 10, an embodiment in which this invention is applied to a wristwatch will be described. As shown in FIG. 1, this wristwatch includes a wristwatch case 1. Band attachment portions 2 to which watch bands (not shown) are attached are provided on the 6 o'clock side and the 12 o'clock side of this wristwatch case 1, respectively. Switch portions 3 are provided on the 2 o'clock side, 4 o'clock side, 8 o'clock side, and 10 o'clock side of this wristwatch case 1, respectively.

[0011] As shown in FIGS. 1 and 2, this wristwatch case 1 includes a lower case 1a, an upper case 1b, and an exterior case 1c. The lower case 1a and the upper case 1b are formed of metal. The upper case 1b is attached to the lower case 1a by a plurality of screws 1e via a waterproof ring 1d. The exterior case 1c is formed of a synthetic resin having elasticity such as urethane resin, covers the upper outer periphery of the upper case 1b, and is attached to the upper case 1b by a plurality of screws 1f.

[0012] As shown in FIG. 2, a watch glass 4 is attached to the upper opening of this wristwatch case 1, that is, the upper opening of the upper case 1b via a packing 4a. A back cover 5 is attached to the lower part of this wristwatch case 1, that is, the lower part of the lower case 1a by a plurality of screws 5b via a waterproof ring 5a. A clock module 6 is provided inside this wristwatch case 1, that is, inside the lower case 1a.

[0013] In this case, a ring-shaped separator member 7 is provided on the inner peripheral portion of the wristwatch case 1 located below the watch glass 4, that is, on the inner peripheral portion of the upper case 1b, as shown in FIGS. 1 and 2. A plurality of hour numerals 7a corresponding to 1 o'clock to 12 o'clock are provided at equal intervals on this separator member 7. This separator member 7 is configured such that a dial 8, which will be described later, of the timepiece module 6 is disposed below it.

[0014] As shown in FIGS. 2 and 3, the timepiece module 6 includes a housing 10 made of synthetic resin. On the upper surface of this housing 10, a solar panel 9 is pressed and attached by a panel pressing member 35, which will be described later. A dial 8 having transparency or semi-transparency and light transmissivity is disposed on the upper surface of this solar panel 9. Further, as shown in FIGS. 2 and 4, a circuit board 11 is attached to the lower surface of the housing 10 by a plurality of screws 11a.

[0015] As shown in FIGS. 2 and 4, a metal pressing plate 12 is disposed on the lower surface of this circuit board 11. This pressing plate 12 is disposed in a region approximately half of the housing 10 extending from a substantially straight line connecting the 3 o'clock side and the 9 o'clock side to the 6 o'clock side. As shown in FIGS. 3 and 9, this pressing plate 12 is configured such that hook portions 12a provided at a plurality of locations on the outer peripheral portion are locked to locking protrusions 10a provided on the outer peripheral surface of the housing 10. Thereby, the pressing plate 12 presses the circuit board 11 against the housing 10 and is attached to the housing 10.

[0016] Further, as shown in FIG. 5, the housing 10 is provided with a display panel 13 for electro-optically displaying various types of information necessary for timepiece functions such as time, date, day of the week, etc., a first timepiece movement 14 for driving the hands 14a such as the minute hand and the hour hand, a second timepiece movement 15 for driving the function hand 15a, and a battery storage portion 16 for storing a button-type battery 17.

[0017] As shown in Figures 2 and 5, the display panel 13 is a planar display element such as a liquid crystal display element or an electroluminescent (EL) display element, formed in a roughly rectangular shape, and positioned diagonally across the 3 o'clock and 6 o'clock sides of the housing 10. This display panel 13 is supported on the circuit board 11 and electrically connected to the circuit board 11 by an interconnector 13a. In this case, as shown in Figure 3, the solar panel 9 is provided with display windows 9a at two locations, the 3 o'clock side and the 6 o'clock side, and is configured so that the information displayed on the display panel 13 can be seen through these display windows 9a.

[0018] As shown in Figure 5, the first clock movement 14 comprises a first stepper motor and a first gear train mechanism and is located approximately in the center of the housing 10. As shown in Figure 3, the first clock movement 14 has a pointer shaft 14b that protrudes above the dial 8 through the solar panel 9 and the dial 8, and a pointer 14a is attached to the upper end of this protruding pointer shaft 14b, and is configured to move this pointer 14a above the dial 8.

[0019] As shown in Figure 5, the second watch movement 15 includes a second step motor and a second gear train mechanism and is located on the 9 o'clock side of the housing 10. As shown in Figure 3, the second watch movement 15 has a function hand shaft 15b that protrudes above the dial 8 through the solar panel 9 and the dial 8, and a function hand 15a is attached to the upper end of this protruding function hand shaft 15b, and is configured to move the function hand 15a above the dial 8.

[0020] As shown in Figures 4 to 6, the battery compartment 16 is formed in the shape of a circular recess approximately the same size as the battery 17 and is located approximately at the 1 o'clock position of the housing 10. The battery compartment 16 is provided with a battery retaining portion 18 that holds down the battery 17 housed inside and electrically connects the electrode surface 17a, which is the negative terminal of the battery 17, to the circuit board 11, and an electrode terminal 20 that electrically connects the outer peripheral surface 17b, which is the positive terminal of the battery 17, to the circuit board 11.

[0021] As shown in Figure 4, the battery retainer portion 18 is provided on a metal retaining plate 12 that holds the circuit board 11 to the housing 10, extending from the 3 o'clock side across the battery storage portion 16 to approximately the 12 o'clock side. The battery retainer portion 18 has multiple contact pieces 18a in its middle section that contact the electrode surface 17a of the battery 17. Furthermore, as shown in Figure 8, when the battery 17 is stored in the battery storage portion 16, the battery retainer portion 18 is configured to bend and bend up at the 3 o'clock side of the retaining plate 12.

[0022] As shown in Figure 4, the battery retainer portion 18 is configured such that the battery hook portion 18b, located at the 12 o'clock end, engages with a locking portion 10b located at the 12 o'clock end of the housing 10, which is located outside the battery storage portion 16. This configuration ensures that when the battery hook portion 18b is engaged with the locking portion 10b at the 12 o'clock end of the housing, the battery retainer portion 18 presses the battery 17 into the battery storage portion 16 while multiple contact pieces 18a are in contact with the electrode surface 17a of the battery 17.

[0023] On the other hand, as shown in Figures 5 to 7, the electrode terminal 20 comprises a main body portion 21 held near the inner circumference of the battery storage portion 16, and a first contact portion 22 provided on the side of the main body portion 21 that contacts the outer surface 17b of the battery 17 housed in the battery storage portion 16. Furthermore, the electrode terminal 20 comprises a second contact portion 23 provided at one end of the main body portion 21 on the circuit board 11 side (the upper end in Figure 7) against which the circuit board 11 is pressed, and a receiving portion 24 provided at the other end of the main body portion 21 opposite to the circuit board 11 (the lower end in Figure 7) against which the non-electrode surface 17c opposite to the electrode surface 17a of the battery 17 is pressed.

[0024] As shown in Figure 7, the electrode terminal 20 is formed integrally from a conductive metal plate such as stainless steel by pressing or bending, with the main body 21, first contact portion 22, second contact portion 23, and receiving portion 24 being formed together. The main body 21 is formed in the shape of a vertical plate and is configured to be held in place by a holding portion 25 provided near the inner circumference of the battery storage portion 16, as shown in Figures 5 and 6.

[0025] In this case, as shown in Figures 5 and 6, the retaining portion 25 holds the main body portion 21 of the electrode terminal 20 at three points, and is provided near the inner circumference of the battery storage portion 16 located on the outer circumference of the housing 10, which is located almost diagonally opposite to the inner circumference of the battery storage portion 16. In other words, this retaining portion 25 is provided near the inner circumference of the battery storage portion 16 located on the inside side of the housing 10, from the 12 o'clock side, in a direction intersecting the longitudinal direction of the battery retaining portion 18. This retaining portion 25 has three retaining wall portions 25a to 25c.

[0026] Of these three retaining walls 25a to 25c, two retaining walls 25a and 25b are provided on the inner circumference of the battery storage section 16, as shown in Figures 5 and 6. The other retaining wall 25c is provided on the outside of the battery storage section 16, with a semi-cylindrical projection corresponding to the space between the two retaining walls 25a and 25b. As a result, the retaining section 25 is configured to hold the main body 21 between the two retaining walls 25a and 25b and the one retaining wall 25c in a tiltable position.

[0027] As shown in Figures 5 to 7, the first contact portion 22 extends from the side of the main body portion 21 along the inner circumferential surface of the battery storage portion 16, and the extended tip portion 22a is bent radially toward the inside of the battery storage portion 16. The tip of the bent tip portion 22a of the first contact portion 22 protrudes into the battery storage portion 16, and this protruding tip is configured to contact the outer circumferential surface 17b of the battery 17 housed in the battery storage portion 16.

[0028] As shown in Figure 7, the tip portion 22a of the first contact portion 22 has a tapered shape, with the side portion 22b facing the circuit board 11 (the upper side in Figure 7) inclined toward the opposite side of the circuit board 11 (the lower side in Figure 7). As a result, as shown in Figure 5, when the outer circumference of the battery 17 comes into contact with the tip portion 22b of the first contact portion 22a that protrudes into the battery storage portion 16 from an oblique upward direction, the outer circumference of the battery 17 slides along the inclined tip portion 22b, thereby housing the battery 17 in the battery storage portion 16.

[0029] In this case, as shown in Figure 5, a terminal storage section 26 is provided along the inner surface of the battery storage section 16, where the first contact portion 22 is located. This terminal storage section 26 is open toward the inside of the battery storage section 16, and the tapered tip of the tip portion 22a of the first contact portion 22 is configured to protrude into the battery storage section 16 from this open area.

[0030] As shown in Figures 5 and 7, the second contact portion 23 extends from one end (the upper end in Figure 7) of the main body portion 21 located on the circuit board 11 side in the same direction as the first contact portion 22, and gradually away from the first contact portion 22, and is formed to extend at an angle toward the circuit board 11 (upper side in Figure 7). As a result, the inclined tip portion 23a of the second contact portion 23 protrudes from the housing 10 toward the circuit board 11 side, and the electrodes (not shown) of the circuit board 11 are pressed against this protruding tip portion 23a.

[0031] In this case, as shown in Figures 6 and 7, the second contact portion 23 is configured to be pressed against the housing 10 by the circuit board 11 when the circuit board 11 is placed on the lower surface (upper surface in Figure 6) of the housing 10 and attached by a plurality of screws 11a. As a result, when the second contact portion 23 is pressed by the circuit board 11, the main body portion 21 is tilted at an inclination angle θ while being held in place by the holding portion 25 of the housing 10, and this tilt of the main body portion 21 causes the first contact portion 22 to tilt at an inclination angle θ toward the opposite side of the circuit board 11 (downward in Figure 7).

[0032] As shown in Figures 5 to 7, the receiving portion 24 is a leaf spring and extends parallel to the bottom surface of the battery storage portion 16 from the other end (lower end in Figure 7) of the main body portion 21, which is located on the opposite side of the circuit board 11, toward the center of the inside of the battery storage portion 16. The tip portion 24a of this receiving portion 24 that extends toward the center of the inside of the battery storage portion 16 is bent at an angle toward the non-electrode surface 17c (upper side in Figure 6) of the battery 17 placed inside the battery storage portion 16.

[0033] As a result, as shown in Figure 5, in the initial state before the circuit board 11 is attached to the housing 10, the electrode terminal 20 is held in the holding portion 25 without the main body portion 21 tilting, the first contact portion 22 is positioned in the terminal storage portion 26 without tilting, the second contact portion 23 is tilted toward the circuit board 11 side from the housing 10, the tip portion 23a is positioned protruding toward the circuit board 11 side from the housing 10, and the receiving portion 24 is positioned parallel to the bottom of the battery storage portion 16.

[0034] Furthermore, as shown in Figure 6, when the circuit board 11 is mounted on the upper surface of the housing 10, the electrode terminal 20 is configured such that the second contact portion 23 is pressed by the circuit board 11, tilting the main body portion 21 at an inclination angle θ, and the first contact portion 22 and the receiving portion 24 tilt in the same direction and at the same inclination angle θ in accordance with this tilt of the main body portion 21.

[0035] Furthermore, in the state shown in Figure 6, when the battery 17 is placed in the battery storage section 16 and pressed down by the battery retainer section 18, the electrode terminal 20 is configured such that the second contact section 23 is pressed against the circuit board 11, and the receiving section 24 is pressed by the non-electrode surface 17c of the battery 17, thereby eliminating the tilt of the receiving section 24, and consequently eliminating the tilt of the main body section 21 and the first contact section 22.

[0036] In other words, in the state shown in Figure 6, the electrode terminal 20 is configured such that when the receiving portion 24 is pressed by the non-electrode surface 17c of the battery 17, the tilt of the receiving portion 24 is eliminated and the receiving portion 24 becomes parallel to the bottom of the battery storage portion 16, the second contact portion 23 is pressed against the circuit board 11, the tilts of the main body portion 21 and the first contact portion 22 are eliminated, and the main body portion 21 is returned to its initial state.

[0037] As a result, when the main body 21 returns to its initial state, the inclination of the first contact portion 22 is eliminated, so that the second contact portion 23 is pressed against the circuit board 11, the first contact portion 22 returns to its initial state, and the tip of the tip portion 22a of the first contact portion 22 is pulled up to approximately the middle of the outer surface 17b of the battery 17 in the thickness direction (vertical direction), so that the tip of the tip portion 22a makes secure contact with the outer surface 17b of the battery 17.

[0038] Incidentally, as shown in Figures 2 and 3, the clock module 6 is equipped with an illumination device 30 that illuminates the dial 8, which is the object to be illuminated. As shown in Figures 9 and 10, the illumination device 30 includes a light-emitting member 31 that illuminates the upper surface of the dial 8, and a mounting adjustment member 32 that holds the light-emitting member 31. The light-emitting member 31 includes a light-emitting part 33 that emits light, and a pair of support legs 34 that are electrically connected to a pair of electrodes (not shown) of the light-emitting part 33 and support the light-emitting part 33.

[0039] As shown in Figures 9 and 10, the light-emitting section 33 is a light source such as a light-emitting diode (LED), and is formed in a chip shape with a rectangular box-like outer shape, and a pair of electrodes are exposed on its back surface. The pair of support legs 34 are formed in a strip shape from a conductive metal. Each of these support legs 34 is positioned on the back surface of the light-emitting section 33 and is attached to the back surface of the light-emitting section 33 in a state where it is electrically connected to the pair of electrodes exposed on the back surface.

[0040] In this case, as shown in Figures 9 and 10, the pair of support legs 34 are formed so that their vertical length is sufficiently longer than the sum of the vertical length of the light-emitting unit 33 and the vertical length of the mounting adjustment member 32. As a result, the pair of support legs 34 are configured to support the light-emitting unit 33 with the light-emitting unit 33 protruding above the mounting adjustment member 32.

[0041] As shown in Figures 3 and 9, the mounting adjustment member 32 is formed in the shape of a substantially rectangular plate from an insulating synthetic resin. This mounting adjustment member 32 is configured to hold a pair of support legs 34 and to adjust the mounting state of the light-emitting part 33 at a predetermined location on the outer circumference of the dial 8, thereby allowing it to be positioned independently. In this case, the mounting adjustment member 32 is provided with a pair of mounting holes 32a that pass through from top to bottom, into which the pair of support legs 34 are inserted. The cross-sectional shape of each of these mounting holes 32a is formed to be the same as the cross-sectional shape of the pair of support legs 34.

[0042] As shown in Figures 3 and 9, the mounting adjustment member 32 is configured to be positioned at a predetermined location on the ring-shaped panel retaining member 35, which is an installation member that presses down on the upper surface of the outer periphery of the solar panel 9 located below the dial 8. In other words, the shape, size, height, and color of the mounting adjustment member 32 are set according to the panel retaining member 35, which differs in shape, size, and height depending on the model of the wristwatch. As a result, the mounting adjustment member 32 is formed to be positioned as a separate part within the mounting storage section 35a provided on the 5 o'clock side of the panel retaining member 35, for example.

[0043] In this case, as shown in Figures 3 and 9, the panel retaining member 35 is positioned on the upper surface of the outer periphery of the housing 10 and is configured to press the upper surface of the outer periphery of the solar panel 9 against the housing 10. Furthermore, this panel retaining member 35 is formed to surround the outer periphery of the dial 8 placed on the solar panel 9. For this reason, the shape, size, and height of this panel retaining member 35 are configured to be set according to the model of the wristwatch.

[0044] Furthermore, as shown in Figures 2 and 9, a notch 36 is provided on the lower part of the housing 10 corresponding to the mounting adjustment member 32, extending from the outer circumference of the housing 10 toward the center of the housing 10 over a wider area than the mounting adjustment member 32. In the housing 10 corresponding to this notch 36, a pair of insertion holes 10c into which the pair of support legs 34 of the light-emitting member 31 are inserted are provided, coaxially with the pair of mounting holes 32a of the mounting adjustment member 32.

[0045] As a result, as shown in Figure 9, the pair of support legs 34 have their lower ends inserted into a pair of insertion holes 10c in the housing 10 and protruding downwards. When the mounting adjustment member 32 is positioned within the mounting storage portion 35a of the panel retaining member 35, the lower ends that protrude downwards from the pair of insertion holes 10c are bent, and these bent portions 34a are pressed against the upper inner surface within the notch portion 36.

[0046] Therefore, as shown in Figures 2 and 9, the pair of support legs 34 are configured so that their bending positions are set according to the height of the panel retaining member 35 and the height of the notch 36 of the housing 10. In this way, the pair of support legs 34 are configured to attach and fix the light-emitting member 31 and the mounting adjustment member 32 to the housing 10 when each bending portion 34a is pressed against the upper inner surface of the notch 36 by the pair of connecting members 37. In this case, the mounting adjustment member 32 is formed so as to position the light-emitting portion 33 on the upper side of the dial 8.

[0047] Furthermore, as shown in Figure 9, a pair of connecting members 37 are arranged within the notch 36 of the housing 10. Each of these connecting members 37 is a coil spring and is held by a mounting member 38. Each of these connecting members 37 is configured such that one end elastically contacts a pair of electrodes (not shown) on a circuit board 11 corresponding to the notch 36 of the housing 10, and the other end elastically contacts each bent portion 34a of a pair of support legs 34.

[0048] As a result, the pair of connecting members 37 are configured to electrically connect the light-emitting unit 33 and the circuit board 11 via a pair of support legs 34, as shown in Figure 9. In this case, the mounting member 38 is formed in the shape of a rectangular plate. The mounting member 38 is provided with a pair of holding holes 38a that pass through from top to bottom to hold the pair of connecting members 37. As a result, the pair of connecting members 37 are inserted into the pair of holding holes 38a of the mounting member 38 and held in a state where they protrude from the top and bottom of the mounting member 38.

[0049] Furthermore, as shown in Figure 2, the trim member 7 positioned above the panel retaining member 35 has a light-emitting storage section 7b in which the light-emitting unit 33 is located, which is open to the inside of the watch case 1. As a result, the lighting device 30 is configured such that the light emitted by the light-emitting unit 33 located in the light-emitting storage section 7b of the trim member 7 is irradiated from the open side of the light-emitting storage section 7b toward the upper surface of the dial 8, thereby illuminating the dial 8.

[0050] Furthermore, as shown in Figure 2, the mounting adjustment member 32 is visible from inside the watch case 1 through the open portion of the light-emitting storage section 7b of the trim member 7, which is open to the inside of the watch case 1. For this reason, it is desirable that the mounting adjustment member 32 be colored in a color that is difficult to see from inside the watch case 1, for example, a color similar to the trim member 7, or black.

[0051] Next, I will explain how to assemble such a watch. In this case, first, the trim member 7 is inserted into the upper opening of the watch case 1 from above. At this time, the light-emitting storage portion 7b of the trim member 7 is aligned with the 5 o'clock position of the watch case 1. With this in place, the watch glass 4 is attached together with the gasket 4a to the upper opening of the watch case 1 located above the trim member 7.

[0052] Then, the watch module 6 is installed inside the watch case 1 from below. At this time, the watch module 6 is assembled in advance. In this case, first, the display panel 13, the first watch movement 14, and the second watch movement 15 are installed in the housing 10. That is, the display panel 13 is placed in the housing 10 from the 3 o'clock side to the 6 o'clock side. The first watch movement 14 is placed in the approximate center of the housing 10, and the second watch movement 15 is placed in the housing 10 at the 9 o'clock side.

[0053] In this state, the solar panel 9 is placed on the upper surface of the housing 10, and the display windows 9a on the 3 o'clock and 6 o'clock sides of the solar panel 9 correspond to the display panel 13. Then, the panel retaining member 35 is placed on the outer periphery of the housing 10, and the upper surface of the outer periphery of the solar panel 9 is pressed down with the panel retaining member 35. At this time, the mounting storage portion 35a provided on the 5 o'clock side of the panel retaining member 35 corresponds to the upper part of the notch portion 36 provided on the 5 o'clock side of the housing 10.

[0054] This makes the lighting device 30 ready for installation. To do this, the lighting device 30 is attached to the mounting storage section 35a of the panel retaining member 35, which presses the solar panel 9 onto the housing 10. In this case, first, a pair of support legs 34 are attached to the back of the light-emitting part 33 of the light-emitting member 31, and a pair of electrodes (not shown) of the light-emitting part 33 are electrically connected to the pair of support legs 34.

[0055] This forms a light-emitting member 31 in which the light-emitting part 33 is supported by a pair of support legs 34. The pair of support legs 34 of this light-emitting member 31 are inserted from above into a pair of mounting holes 32a of the mounting adjustment member 32 and protrude downwards. In this way, the light-emitting member 31 is attached to the mounting adjustment member 32. In this state, the mounting adjustment member 32 is placed as a separate part inside the mounting storage section 35a of the panel retaining member 35. In this case, the shape, size, height, and color of the mounting adjustment member 32 are set according to the panel retaining member 35, which differs in shape, size, and height depending on the watch model.

[0056] Then, a pair of support legs 34 protruding from the lower side of the mounting adjustment member 32 are inserted into a pair of insertion holes 10c of the housing 10 located below the mounting storage portion 35a of the panel retaining member 35, causing them to protrude into the notch portion 36 of the housing 10. In this state, the pair of support legs 34 protruding into the notch portion 36 are bent, and each bent portion 34a of the pair of support legs 34 is pressed against the upper inner surface inside the notch portion 36.

[0057] As a result, the mounting adjustment member 32 and the light-emitting member 31 are attached and fixed to the housing 10 by the bent portions 34a of the pair of support legs 34. In this state, the light-emitting portion 33 of the light-emitting member 31 is positioned above the panel retaining member 35, and the pair of connecting members 37 can be positioned below the bent portions 34a of the pair of support legs 34. As a result, the lighting device 30 is mounted on the 5 o'clock side of the housing 10 with the mounting storage portion 35a of the panel retaining member 35 in place.

[0058] Meanwhile, in this state, the electrode terminals 20 are attached to the vicinity of the inner circumference of the battery storage section 16 of the housing 10. At this time, the main body 21 of the electrode terminals 20 is inserted into the holding section 25 provided near the inner circumference of the battery storage section 16 and held in place. That is, the main body 21 is inserted between the two holding walls 25a and 25b and the one holding wall 25c of the holding section 25 and held in place by being sandwiched between them.

[0059] In this case, the first contact portion 22 of the electrode terminal 20 is positioned within the terminal housing portion 26 provided on the inner circumference of the battery housing portion 16. That is, the first contact portion 22 extends from the side of the main body portion 21 along the inner surface of the battery housing portion 16, and this extended tip portion 22a is bent radially toward the inside of the battery housing portion 16, with the tip of this bent tip portion 22a protruding from the terminal housing portion 26 into the battery housing portion 16.

[0060] Furthermore, at this time, the second contact portion 23 of the electrode terminal 20 is positioned on the side of the circuit board 11 (upper side in Figure 7) to which the housing 10 is attached. That is, the second contact portion 23 extends from one end (upper end in Figure 7) of the main body portion 21 located on the circuit board 11 side in approximately the same direction as the first contact portion 22, and gradually away from the first contact portion 22, and is inclined toward the circuit board 11 side (upper side in Figure 7), with its tip portion 23a protruding from the housing 10 toward the circuit board 11 side.

[0061] Simultaneously, the receiving portion 24 of the electrode terminal 20 is positioned at the bottom of the battery compartment 16 on the opposite side of the circuit board 11. That is, this receiving portion 24 extends parallel to the bottom surface of the battery compartment 16 from the other end of the main body portion 21 (the lower end in Figure 7) toward the center of the inside of the battery compartment 16, and this extended tip portion 24a is positioned at an angle toward the non-electrode surface 17c side (upper side in Figure 7) of the battery 17 that is placed inside the battery compartment 16.

[0062] This state is the initial state of the electrode terminal 20. That is, this initial state is the state before the circuit board 11 is attached to the housing 10. In this initial state, the main body 21 is held by the holding part 25 without tilting, and the first contact part 22 is positioned in the terminal storage part 26 without tilting. The second contact part 23 is tilted toward the circuit board 11 side from the housing 10, with the tip part 23a protruding toward the circuit board 11 side from the housing 10, and the receiving part 24 is positioned parallel to the bottom of the battery storage part 16.

[0063] In this state, as shown in Figure 9, the circuit board 11 is placed on the lower surface of the housing 10 and attached with a plurality of screws 11a. At this time, a pair of connecting members 37 for electrically connecting the lighting device 30 to the circuit board 11 are held in a pair of holding holes 38a of the mounting member 38, and the mounting member 38 is used to position the pair of connecting members 37 within the notch 36 of the housing 10, so that they correspond to the lower side of each bent portion 34a of the pair of support legs 34 of the lighting device 30.

[0064] In this state, when the circuit board 11 is attached to the lower surface of the housing 10, one end of the pair of connecting members 37 elastically contacts a pair of electrodes (not shown) on the circuit board 11, and the other end of each member elastically contacts the bent portions 34a of the pair of support legs 34. As a result, the light-emitting unit 33 and the circuit board 11 are electrically connected by the pair of connecting members 37 and the pair of support legs 34.

[0065] Incidentally, when the circuit board 11 is attached to the housing 10, as shown in Figure 6, the circuit board 11 is pressed against the second contact portion 23 of the electrode terminal 20, and the second contact portion 23 is pressed so that it bends toward the housing 10 side (downward in Figure 7). As a result, the main body portion 21 is tilted at an angle θ while being held in place by the holding portion 25 of the housing 10, and the first contact portion 22 tilts toward the opposite side of the circuit board 11 at an angle θ as the main body portion 21 tilts toward the opposite side at the same angle θ, and the receiving portion 24 also tilts toward the same direction at the same angle θ.

[0066] Next, a metal retaining plate 12 is placed on the underside of the circuit board 11 and attached. At this time, the retaining plate 12 is positioned over approximately half of the area of ​​the housing 10, from the almost straight line connecting the 3 o'clock and 9 o'clock sides of the circuit board 11 to the 6 o'clock side, and hook portions 12a provided at multiple locations on the outer circumference of the retaining plate 12 are engaged with locking projections 10a provided on the outer circumference of the housing 10. In this way, the retaining plate 12 presses the circuit board 11 against the housing 10 and attaches it to the housing 10.

[0067] In this state, the battery retainer portion 18, located on the 3 o'clock side of the retaining plate 12, extends from the 3 o'clock side across the battery storage portion 16 and is positioned approximately towards the 12 o'clock side. In this state, the battery hook portion 18b, located at the 12 o'clock end of the battery retainer portion 18, becomes capable of engaging with the locking portion 10b, located on the 12 o'clock side of the housing 10, which is located outside the battery storage portion 16. This makes it possible to store the battery 17 in the battery storage portion 16.

[0068] Then, when storing the battery 17 in the battery compartment 16, first, the battery hook portion 18b of the battery retainer portion 18 is released from the locking portion 10b on the 12 o'clock side of the housing 10, and the battery retainer portion 18 is raised away from the battery compartment 16 (see Figure 8). This opens the battery compartment 16, allowing the battery 17 to be inserted into it. At this time, the battery 17 is inserted into the battery compartment 16 from diagonally above, in a direction approximately perpendicular to the longitudinal direction of the battery retainer portion 18, from the outer circumference side of the housing 10.

[0069] In this case, the outer circumference of the battery 17 comes into contact with the tip 22a of the first contact portion 22 of the electrode terminal 20, which is located near the inner circumference of the battery storage portion 16, from an oblique upward direction. At this time, the first contact portion 22 is tilted at an angle θ toward the opposite side of the circuit board 11 (downward in Figure 7), so the outer circumference of the battery 17 slides smoothly along the tilt of the first contact portion 22, and the battery 17 is stored in the battery storage portion 16.

[0070] Furthermore, at this time, the edge portion 22b (upper edge portion in Figure 7) of the tip portion 22a of the first contact portion 22 that faces the circuit board 11 is inclined toward the opposite side of the circuit board 11, and the tip of the tip portion 22a is formed in a tapered shape, so the outer circumference of the battery 17 comes into contact with the edge portion 22b of the tapered tip portion 22a of the first contact portion 22 from an oblique upward side.

[0071] At this time, the first contact portion 22 is tilted at an angle θ toward the opposite side of the circuit board 11 (downward in Figure 7), and the edge portion 22b of the tip portion 22a is further tilted toward the opposite side of the circuit board 11. The outer circumference of the battery 17 slides even more smoothly along this tilted edge portion 22b, and the battery 17 is stored in the battery storage portion 16. Therefore, even if the tip portion 22a of the first contact portion 22 protrudes into the battery storage portion 16, the tip portion 22a of the first contact portion 22 does not get in the way, and the battery 17 is easily and well stored in the battery storage portion 16.

[0072] In this state, the battery retainer portion 18 is placed on the battery 17, and the battery hook portion 18b provided at the 12 o'clock end of the battery retainer portion 18 is locked to the 12 o'clock locking portion 10b of the housing 10 located outside the battery storage portion 16. As a result, with the contact piece 18a of the battery retainer portion 18 in contact with the electrode surface 17a of the battery 17, the battery retainer portion 18 presses the battery 17 into the battery storage portion 16.

[0073] At this time, the battery 17 is pressed into the battery storage section 16 by the battery retainer 18, so that with the second contact section 23 pressed against the circuit board 11, the non-electrode surface 17c of the battery 17 presses against the receiving section 24, eliminating the tilt of the receiving section 24, and consequently eliminating the tilt of the main body section 21 and the first contact section 22. In other words, the receiving section 24 is pressed by the non-electrode surface 17c of the battery 17, eliminating the tilt of the receiving section 24, and the receiving section 24 becomes parallel to the bottom of the battery storage section 16.

[0074] As a result, the inclinations of the main body 21 and the first contact portion 22 are eliminated, and the main body 21 and the first contact portion 22 return to their initial state. That is, in the state shown in Figure 6, when the main body 21 returns to its initial state, the second contact portion 23 is pressed against the circuit board 11 and electrically stably connected to the circuit board 11, and the first contact portion 22 also returns to its initial state, the tip of the tip portion 22a is pulled up and corresponds to approximately the middle of the outer surface 17b of the battery 17 in the thickness direction (vertical direction), and the tip of the tip portion 22a makes secure and good contact with the outer surface 17b of the battery 17. As a result, the battery 17 is electrically connected to the circuit board 11 by the electrode terminals 20 and the battery retaining portion 18.

[0075] Then, the watch module 6 is assembled into the watch case 1. In this case, the dial 8 is placed on the solar panel 9 located on the upper surface of the housing 10, and the outer edge of the dial 8 is surrounded by the panel retaining member 35. At this time, the pointer shaft 14b of the first watch movement 14 protrudes above the dial 8, and the function needle shaft 15b of the second watch movement 15 protrudes above the dial 8. In this state, the pointer 14a is attached to the pointer shaft 14b of the first watch movement 14, and the function needle 15a is attached to the function needle shaft 15b of the second watch movement 15, and the watch module 6 is assembled into the watch case 1, with the dial 8 positioned below the bezel member 7.

[0076] At this point, the light-emitting part 33 of the lighting device 30, which is positioned above the panel retaining member 35, is placed inside the light-emitting storage part 7b of the trim member 7 and positioned above the dial 8. This ensures that the clock module 6 is properly incorporated into the watch case 1. After this, the switch parts 3 are attached to the 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock sides of the watch case 1, and the back cover 5 is attached to the bottom of the watch case 1 together with the waterproof ring 5a. This completes the assembly of the watch.

[0077] Next, we will explain how to use this type of watch. In this wristwatch, the hands 14a are normally moved above the dial 8 by the first watch movement 14 to indicate the time, and the function hands 15a are moved above the dial 8 by the second watch movement 15 to indicate the function. In addition, information such as the time, day of the week, and date displayed on the display panel 13 is visible from above the dial 8 through the display windows 9a at the 3 o'clock and 6 o'clock positions of the solar panel 9.

[0078] Furthermore, when using this watch in dark places such as at night, the illumination mode is selected by operating one of the multiple switch sections 3 on the 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock sides, causing the light-emitting section 33 of the light-emitting member 31 of the illumination device 30 to emit light and illuminate the dial 8. Specifically, the light-emitting section 33 is positioned above the dial 8 by the mounting adjustment member 32 and is placed inside the light-emitting storage section 7b of the trim member 7. Since this light-emitting storage section 7b is open to the dial 8 side, the light emitted by the light-emitting section 33 is shone onto the upper surface of the dial 8 from this open area.

[0079] As a result, in this wristwatch, even in dark places, the dial 8 is illuminated by the illumination device 30, so the time indication display by the hands 14a, the function indication display by the function hands 15a, and the information display by the display panel 13 can be clearly seen. In this case, the light-emitting storage section 7b of the bezel member 7 is open to the dial 8 side.

[0080] Therefore, even if the mounting adjustment member 32 is visible from the inside of the watch case 1 through this open section, because the mounting adjustment member 32 is colored in the same color family as the trim member 7, or black, it becomes difficult to see the mounting adjustment member 32 from the inside of the watch case 1, thereby enhancing the design.

[0081] Thus, the illumination device 30 of this wristwatch provides a highly versatile device by comprising a light-emitting member 31 having a light-emitting part 33 that illuminates the dial 8, which is the object to be illuminated, provided on the upper surface of the housing 10, and a pair of support legs 34 that are connecting parts that support the light-emitting part 33 and are provided from the lower side of the housing to the light-emitting part 33, and a mounting adjustment member 32 that holds the pair of support legs 34 and adjusts the installation state of the light-emitting part 33 to a predetermined location on the outer circumference of the dial 8, and is positioned independently of the housing 10.

[0082] In other words, in the lighting device 30 of this wristwatch, by independently arranging the mounting adjustment member 32 that holds the light-emitting member 31 at a predetermined location on the outer circumference of the housing 10 on the outer edge of the dial 8, the mounting adjustment member 32 adjusts the installation state of the light-emitting unit 33, allowing the light-emitting unit 33 to be installed in an optimal state relative to the housing 10, thus providing a highly versatile device.

[0083] In this case, the lighting device 30 of this wristwatch has a panel retaining member 35, which is an installation member installed on the outer circumference of the dial 8 to hold the dial 8. The shape, size, and height of the mounting adjustment member 32 are individually set according to this panel retaining member 35. For example, even if the shape, size, and height of the panel retaining member 35 differ depending on the model of the wristwatch, the mounting adjustment member 32 can be set to the optimal shape, size, and height according to the panel retaining member 35, thereby installing the light-emitting unit 33 in the optimal state.

[0084] Furthermore, in the lighting device 30 of this wristwatch, the mounting adjustment member 32 is arranged as a separate part within the mounting storage section 35a provided in the panel retaining member 35. For example, even if other components such as a solar panel 9 are placed below the dial 8 and the height of the dial 8 changes, the mounting adjustment member 32 can be positioned according to the height of the dial 8, allowing the height of the light-emitting part 33 of the light-emitting member 31 to be optimally set.

[0085] Furthermore, in the lighting device 30 of this wristwatch, the pair of support legs 34 of the light-emitting member 31 are electrically connected to the circuit board 11 located on the underside of the dial 8. This ensures that even if the shape, size, and height of the mounting adjustment member 32 are changed according to the panel retaining member 35, the pair of support legs 34 can reliably and effectively connect the light-emitting unit 33 and the circuit board electrically.

[0086] In other words, in the lighting device 30 of this wristwatch, a pair of mounting holes 32a are provided through the mounting adjustment member 32 into which a pair of support legs 34 are inserted. The pair of support legs 34 protrude through the pair of mounting holes 32a to the side opposite the light-emitting part 33, and each of these protruding ends is bent to form a bent portion 34a. These bent portions 34a of the pair of support legs 34 allow the mounting adjustment member 32 to be attached to a predetermined location on the outer circumference of the dial 8, thereby securely holding the light-emitting member 31.

[0087] Furthermore, in the lighting device 30 of this wristwatch, each bent portion 34a of the pair of support legs 34 is set to a bent position in accordance with the panel retaining member 35 and electrically connected to the circuit board 11. Therefore, even if the height of the panel retaining member 35 changes, the mounting adjustment member 32 can be securely attached to a predetermined location on the outer circumference of the dial 8 by changing the bent position of each bent portion 34a of the pair of support legs 34. In addition, because the bent portions 34a are electrically connected to the circuit board 11, the light-emitting unit 33 can be electrically and reliably connected to the circuit board 11 via the pair of support legs 34.

[0088] In this case, even if other components such as a solar panel 9 are positioned below the dial 8, and the height of the panel retaining member 35 changes, the mounting adjustment member 32 can be securely attached to a predetermined location on the outer circumference of the dial 8 by changing the bending position of each bent portion 34a of the pair of support legs 34.

[0089] Furthermore, in the illumination device 30 of this wristwatch, the mounting adjustment member 32 holds the light-emitting part 33 of the light-emitting member 31 above the dial 8. Therefore, even if the height of the dial 8 changes due to the panel retaining member 35, the mounting adjustment member 32 holds the light-emitting part 33 above the dial 8, ensuring that the light emitted from the light-emitting part 33 is reliably directed onto the upper surface of the dial 8, thereby providing good illumination of the dial 8.

[0090] In the above-described embodiment, the case where the illumination device 30 is installed on the 5 o'clock side of the dial 8 was mentioned. However, this invention does not necessarily require the illumination device to be installed on the 5 o'clock side; it can be installed anywhere on the outer circumference of the dial 8.

[0091] Furthermore, while the above-described embodiment described the case where the lighting device 30 illuminates the dial 8, this invention does not necessarily require the lighting device to illuminate the dial 8; for example, it may also illuminate the display panel 13. In this case, the lighting device 30 can be placed around the outer periphery of the display panel 13.

[0092] Furthermore, although the embodiments described above focused on the application of the invention to wristwatches, this invention is not necessarily limited to wristwatches and can be applied to various types of clocks, such as travel watches, alarm clocks, desk clocks, and wall clocks. Moreover, this invention is not necessarily limited to clocks and can be applied to various electronic devices, such as mobile phones and personal digital assistants.
