The retainer plate 12 is disposed in approximately half of the area 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, the retainer plate 12 is configured so that hook portions 12a provided at multiple locations on the outer periphery are engaged with locking protrusions 10a provided on the outer periphery of the housing 10. In this way, the retainer plate 12 is attached to the housing 10 by pressing the circuit board 11 against the housing 10.

[0016] As shown in FIG. 5, the housing 10 is provided with a display panel 13 that electro-optically displays various information necessary for the timekeeping functions, such as the time, date, and day of the week, a first clock movement 14 that moves hands 14a such as the minute hand and hour hand, a second clock movement 15 that moves function hand 15a, and a battery storage section 16 that stores a button-type battery 17.

[0017] 2 and 5, display panel 13 is a flat display element such as a liquid crystal display element or an EL (electroluminescence) display element, and is formed in a substantially rectangular shape and disposed diagonally across the 3 o'clock and 6 o'clock sides of housing 10. Display panel 13 is supported on circuit board 11 while being electrically connected to circuit board 11 by interconnectors 13a. In this case, solar panel 9 is provided with display windows 9a at two locations, on the 3 o'clock and 6 o'clock sides, as shown in FIG. 3, and is configured so that information displayed on display panel 13 can be seen through these display windows 9a.

[0018] As shown in Fig. 5, the first timepiece movement 14 includes a first step motor and a first gear train mechanism, and is located approximately in the center of the housing 10. As shown in Fig. 3, this first timepiece movement 14 is configured such that a hand arbor 14b protrudes above the dial 8 through the solar panel 9 and the dial 8, and a hand 14a is attached to the upper end of this protruding hand arbor 14b, and the hand 14a moves above the dial 8.

[0019] As shown in Fig. 5, the second timepiece movement 15 includes a second step motor and a second gear train mechanism, and is provided on the 9 o'clock side of the housing 10. As shown in Fig. 3, the second timepiece movement 15 is configured such that a function hand axis 15b 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 axis 15b, and this function hand 15a moves above the dial 8.

[0020] 4 to 6, battery storage section 16 is formed in a circular recess shape that is approximately the same size as battery 17, and is provided at approximately the 1 o'clock side of housing 10. Battery storage section 16 is provided with battery pressing section 18 that presses down battery 17 stored therein and electrically connects electrode surface 17a, which is the negative pole of battery 17, to circuit board 11, and electrode terminal 20 that electrically connects outer peripheral surface 17b, which is the positive pole of battery 17, to circuit board 11.

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

[0022] 4, this battery retainer 18 is configured so that a battery hook portion 18b provided at the tip on the 12 o'clock side is engaged with a locking portion 10b provided on the 12 o'clock side of the housing 10 located outside the battery storage portion 16. As a result, when the battery hook portion 18b is engaged with the locking portion 10b on the 12 o'clock side of the housing, the battery retainer 18 is configured to press the battery 17 into the battery storage portion 16 with the multiple contact pieces 18a in contact with the electrode surface 17a of the battery 17.

[0023] 5 to 7, the electrode terminal 20 includes a main body 21 that is held near the inner periphery of the battery housing section 16, and a first contact portion 22 that is provided on the side of the main body 21 and that comes into contact with the outer periphery 17b of the battery 17 housed in the battery housing section 16. The electrode terminal 20 also includes a second contact portion 23 that is provided at one end of the main body 21 on the circuit board 11 side (the upper end in FIG. 7) and against which the circuit board 11 is pressed, and a receiving portion 24 that is provided at the other end of the main body 21 opposite the circuit board 11 (the lower end in FIG. 7) and against which the non-electrode surface 17c of the battery 17 opposite the electrode surface 17a is pressed.

[0024] 7, this electrode terminal 20 is formed by bending a conductive metal plate such as stainless steel through pressing or sheet metal processing, thereby integrating a main body portion 21, a first contact portion 22, a second contact portion 23, and a receiving portion 24. The main body portion 21 is formed in the shape of a vertical flat plate, and is configured to be sandwiched and held by a holding portion 25 provided near the inner periphery of the battery storage portion 16, as shown in FIGS.

[0025] 5 and 6, the holding portion 25 holds the main body 21 of the electrode terminal 20 at three points, and is provided near the inner periphery of the battery accommodating portion 16 located approximately diagonally to the inner periphery of the battery accommodating portion 16 located on the outer periphery of the housing 10. In other words, the holding portion 25 is provided near the inner periphery of the battery accommodating portion 16 located inside the housing 10 from the 12 o'clock side, in a direction intersecting the longitudinal direction of the battery pressing portion 18. The holding portion 25 has three holding walls 25a to 25c.

[0026] 5 and 6, two of the three holding walls 25a to 25c, 25a and 25b, are provided on the inner periphery of the battery housing section 16. The remaining holding wall 25c is provided on the outer side of the battery housing section 16, with its semi-cylindrical protrusion positioned between the two holding walls 25a and 25b. As a result, the holding section 25 is configured to sandwich and hold the main body section 21 between the two holding walls 25a and 25b and the holding wall 25c in a tiltable manner.

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

[0028] 7, the tip 22a of this first contact portion 22 is formed in a tapered shape, with the side portion (upper side in FIG. 7) 22b facing the circuit board 11 inclined toward the opposite side (lower side in FIG. 7) from the circuit board 11. As a result, the tip 22a of the first contact portion 22 is configured so that when the outer periphery of the battery 17 abuts against the tip side 22b protruding into the battery housing section 16 from above, as shown in FIG. 5, the outer periphery of the battery 17 slides along the inclined tip side 22b, causing the battery 17 to be housed in the battery housing section 16.

[0029] 5, a terminal storage section 26 in which the first contact portion 22 is disposed is provided along the inner peripheral surface of the battery storage section 16. This terminal storage section 26 is open toward the inside of the battery storage section 16, and is configured so that the tapered tip of the tip portion 22a of the first contact portion 22 protrudes into the battery storage section 16 from this open portion.

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

[0031] 6 and 7, when the circuit board 11 is disposed on the lower surface of the housing 10 (the upper surface in FIG. 6) and attached with a plurality of screws 11a, the second contact portion 23 is configured to be pressed against the housing 10 by the circuit board 11. As a result, when the second contact portion 23 is pressed by the circuit board 11, the main body 21 is configured to tilt at an inclination angle θ while being clamped between the holding portions 25 of the housing 10, and in conjunction with this tilt of the main body 21, the first contact portion 22 is tilted at the inclination angle θ toward the side opposite the circuit board 11 (the downward side in FIG. 7).

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

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

[0034] Furthermore, as shown in FIG. 6, when the circuit board 11 is placed and attached to the upper surface of the housing 10, the second contact portion 23 is pressed by the circuit board 11, tilting the main body portion 21 at an inclination angle θ, and as the main body portion 21 tilts, the first contact portion 22 and the receiving portion 24 tilt in the same direction at the same inclination angle θ.

[0035] Furthermore, this electrode terminal 20 is configured so that when a battery 17 is placed in the battery storage section 16 and pressed down by the battery pressing section 18 in the state shown in Figure 6, 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, eliminating the inclination of the receiving section 24, and as a result, the inclination of the main body section 21 and the first contact section 22 is also eliminated.

[0036] That is, in the state shown in Figure 6, this electrode terminal 20 is configured so that when the non-electrode surface 17c of the battery 17 presses the receiving portion 24, eliminating the inclination of the receiving portion 24, and the receiving portion 24 becomes parallel to the bottom of the battery storage section 16, the second contact portion 23 is pressed against the circuit board 11, eliminating the inclination of the main body portion 21 and the first contact portion 22, and returning the main body portion 21 to its initial state.

[0037] As a result, when the main body 21 of the electrode terminal 20 returns to its initial state in the state shown in Figure 6, the tilt of the first contact portion 22 is eliminated, and so with the second contact portion 23 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 thickness direction (vertical direction) of the outer surface 17b of the battery 17, so that the tip of the tip portion 22a is securely in contact with the outer surface 17b of the battery 17.

[0038] As shown in Figures 2 and 3, the timepiece 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, this illumination device 30 is equipped with a light-emitting member 31 that illuminates the top surface of the dial 8, and an attachment adjustment member 32 that holds this light-emitting member 31. The light-emitting member 31 is equipped with a light-emitting section 33 that emits light, and a pair of support legs 34 that are connecting parts that are electrically connected to a pair of electrodes (not shown) of this light-emitting section 33 and support the light-emitting section 33.

[0039] 9 and 10, the light-emitting unit 33 is a light source such as a light-emitting diode (LED), and is formed in the shape of a chip with a rectangular box-like outer shape, with a pair of electrodes exposed on its back surface. The pair of support legs 34 are formed in the shape of a strip made of conductive metal. Each of the pair of support legs 34 is disposed on the back surface of the light-emitting unit 33 and attached to the back surface of the light-emitting unit 33 in a state of being electrically connected to the pair of electrodes exposed on the back surface side.

[0040] 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 lengths of the light emitting unit 33 and the attachment 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 attachment adjustment member 32.

[0041] As shown in Figures 3 and 9, the mounting adjustment member 32 is formed in a substantially rectangular plate shape from an insulating synthetic resin. This mounting adjustment member 32 is configured to adjust the installation state of the light-emitting unit 33 at a predetermined location on the outer periphery of the dial 8 while holding a pair of support legs 34, and to position it independently. In this case, a pair of mounting holes 32a, into which the pair of support legs 34 are respectively inserted, are formed to penetrate the mounting adjustment member 32 vertically. The cross-sectional shape of each of the pair of mounting holes 32a is formed to be the same shape as the cross-sectional shape of the pair of support legs 34.

[0042] 3 and 9, this attachment adjustment member 32 is configured to be placed in a predetermined position on a ring-shaped panel retaining member 35, which is an installation member that presses down on the upper surface of the outer periphery of solar panel 9 that is placed below dial 8. That is, the shape, size, height, color, etc. of this attachment adjustment member 32 are set according to the shape, size, height, etc. of panel retaining member 35, which vary in shape, size, and height depending on the model of wristwatch. As a result, this attachment adjustment member 32 is formed so that it can be placed as a separate part in attachment storage section 35a provided on the 5 o'clock side of panel retaining member 35, for example.

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

[0044] 2 and 9, a cutout 36 is provided in the lower part of the housing 10 corresponding to the attachment adjustment member 32, extending from the outer periphery of the housing 10 toward the center of the housing 10 over a wider area than the attachment adjustment member 32. A pair of insertion holes 10c, into which the pair of support legs 34 of the light emitting member 31 are inserted, are provided in the housing 10 corresponding to this cutout 36, coaxially with the pair of attachment holes 32a of the attachment 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 of the housing 10 and protruding downward, and when the mounting adjustment member 32 is placed in the mounting storage portion 35a of the panel pressing member 35, each lower end protruding downward from the pair of insertion holes 10c is bent, and each of these bent portions 34a is pressed against the upper inner surface of the cutout portion 36.

[0046] 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 cutout portion 36 of the housing 10. As a result, the pair of support legs 34 are configured so that the light emitting member 31 and the attachment adjustment member 32 are attached and fixed to the housing 10 when each bent portion 34a is pressed against the upper inner surface of the cutout portion 36 by the pair of connecting members 37. In this case, the attachment adjustment member 32 is formed so that the light emitting portion 33 is positioned above the dial 8.

[0047] 9, a pair of connecting members 37 are disposed within the cutout portions 36 of the housing 10. Each of the pair of connecting members 37 is a coil spring and is held by an attachment member 38. One end of each of the pair of connecting members 37 is configured to elastically contact a pair of electrodes (not shown) on the circuit board 11 that correspond to the cutout portions 36 of the housing 10, and the other end of each of the pair of connecting members 37 is configured to elastically contact the bent portions 34a of the pair of support legs 34, respectively.

[0048] 9, the pair of connecting members 37 are configured to electrically connect the light-emitting unit 33 and the circuit board 11 via the pair of support legs 34. In this case, the mounting member 38 is formed in a rectangular plate shape. A pair of holding holes 38a that hold the pair of connecting members 37 is provided so as to penetrate the mounting member 38 from top to bottom. As a result, the pair of connecting members 37 are configured to be 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] 2, the parting member 7 arranged above the panel retaining member 35 has a light-emitting storage section 7b in which the light-emitting section 33 is arranged, which is open to the inside of the watch case 1. As a result, the lighting device 30 is configured so that light emitted by the light-emitting section 33 arranged in the light-emitting storage section 7b of the parting member 7 is irradiated from the open side of the light-emitting storage section 7b toward the top surface of the dial 8, illuminating the dial 8.

[0050] 2, the light-emitting storage section 7b of the parting member 7 is open to the inside of the watch case 1, and so the attachment adjustment member 32 can be seen through this open section from inside the watch case 1. For this reason, it is desirable that the attachment 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 that of the parting member 7 or black.

[0051] Next, the assembly of such a wristwatch will be described. In this case, first, the parting member 7 is inserted from above into the upper opening of the watch case 1. At this time, the light-emitting storage section 7b of the parting member 7 is aligned with the 5 o'clock side of the watch case 1. In this state, the watch crystal 4 is attached to the upper opening of the watch case 1 located above the parting member 7, together with the packing 4a.

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

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

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

[0055] This forms the light emitting member 31, with the light emitting section 33 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, causing them to protrude downward. This attaches the light emitting member 31 to the mounting adjustment member 32. In this state, the mounting adjustment member 32 is placed as a separate part in the mounting storage section 35a of the panel press member 35. In this case, the shape, size, height, color, etc. of the mounting adjustment member 32 are set according to the panel press member 35, whose shape, size, height, etc. vary depending on the model of wristwatch.

[0056] Then, the pair of support legs 34 protruding below the mounting adjustment member 32 are inserted into the pair of insertion holes 10c of the housing 10 located below the mounting storage portion 35a of the panel presser member 35, so that they protrude into the cutout portion 36 of the housing 10. In this state, the pair of support legs 34 protruding into the cutout portion 36 are bent, and each bent portion 34a of the pair of support legs 34 is pressed against the upper inner surface of the cutout 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 placed below the bent portions 34a of the pair of support legs 34. As a result, the lighting device 30 is attached to the 5 o'clock side of the housing 10 while being placed in the mounting storage portion 35a of the panel retaining member 35.

[0058] Meanwhile, in this state, the electrode terminal 20 is attached near the inner periphery of the battery storage section 16 of the housing 10. At this time, the main body 21 of the electrode terminal 20 is inserted into and held in the holding section 25 provided near the inner periphery of the battery storage section 16. That is, the main body 21 is inserted and held between the two holding walls 25a, 25b and one holding wall 25c of the holding section 25.

[0059] At this time, the first contact portion 22 of the electrode terminal 20 is disposed within the terminal housing portion 26 provided on the inner periphery 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 periphery of the battery housing portion 16, and the extended tip portion 22 a is bent radially toward the inside of the battery housing portion 16, with the tip of the bent tip portion 22 a protruding from the terminal housing portion 26 into the battery housing portion 16.

[0060] In this case, the second contact portion 23 of the electrode terminal 20 is disposed on the circuit board 11 side (upper side in FIG. 7) attached to the housing 10. That is, the second contact portion 23 extends from one end (upper end in FIG. 7) of the main body portion 21 located on the circuit board 11 side in substantially the same direction as the first contact portion 22 and in a direction gradually moving away from the first contact portion 22, and is inclined toward the circuit board 11 side (upper side in FIG. 7), with the tip portion 23a projecting from the housing 10 toward the circuit board 11 side.

[0061] At the same time, the receiving portion 24 of the electrode terminal 20 is disposed at the bottom of the battery housing portion 16 on the opposite side to the circuit board 11. That is, the receiving portion 24 extends from the other end (the lower end in FIG. 7) of the main body portion 21 toward the center of the interior of the battery housing portion 16 in parallel with the bottom surface of the battery housing portion 16, and the extended tip portion 24a is disposed at an angle toward the non-electrode surface 17c side (the upper side in FIG. 7) of the battery 17 disposed in the battery housing portion 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 portion 25 without tilting, and the first contact portion 22 is placed in the terminal storage portion 26 without tilting. In addition, the second contact portion 23 is tilted from the housing 10 toward the circuit board 11, with the tip portion 23a positioned to protrude from the housing 10 toward the circuit board 11, and the receiving portion 24 positioned parallel to the bottom of the battery storage portion 16.

[0063] 9, the circuit board 11 is placed on the underside 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 is held in advance in a pair of retaining holes 38a of the mounting member 38, and the pair of connecting members 37 are placed in the cutout portions 36 of the housing 10 by the mounting member 38 so that they correspond to the undersides of the bent portions 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 each of the pair of connecting members 37 elastically contacts a pair of electrodes (not shown) of the circuit board 11, and the other end of each of the connecting members 37 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] When the circuit board 11 is attached to the housing 10, the circuit board 11 is pressed against the second contact portions 23 of the electrode terminals 20, and the second contact portions 23 are pressed so as to bend toward the housing 10 (downward in FIG. 7), as shown in Fig. 6. As a result, the main body 21 is inclined at an inclination angle θ while being sandwiched between the holding portions 25 of the housing 10, and in conjunction with this inclination of the main body 21, the first contact portions 22 are inclined at an inclination angle θ toward the side opposite the circuit board 11, and the receiving portions 24 are also inclined in the same direction at the same inclination angle θ.

[0066] Then, a metal presser plate 12 is placed and attached to the underside of the circuit board 11. At this time, the presser plate 12 is placed over approximately half of the area of ​​the housing 10, extending from a substantially 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 periphery of the presser plate 12 are engaged with locking protrusions 10a provided on the outer periphery of the housing 10. In this way, the presser plate 12 presses the circuit board 11 against the housing 10, attaching it to the housing 10.

[0067] At this time, battery retainer 18, located on the 3 o'clock side of retainer plate 12, is positioned so that it extends from the 3 o'clock side to approximately the 12 o'clock side across battery storage section 16. In this state, battery hook 18b, located at the tip of battery retainer 18 on the 12 o'clock side, is able to engage with locking portion 10b, located on the 12 o'clock side of housing 10, located outside battery storage section 16. This makes it possible to store battery 17 in battery storage section 16.

[0068] When storing the battery 17 in the battery storage section 16, first, the battery hook section 18b of the battery retaining section 18 is released from the locking section 10b on the 12 o'clock side of the housing 10, and the battery retaining section 18 is raised in a direction away from the battery storage section 16 (see FIG. 8). This opens the battery storage section 16, allowing the battery 17 to be inserted into the battery storage section 16. At this time, the battery 17 is inserted from above obliquely into the battery storage section 16 from the outer periphery of the housing 10 in a direction substantially perpendicular to the longitudinal direction of the battery retaining section 18.

[0069] In this case, the outer periphery of the battery 17 abuts from diagonally above against the tip 22a that protrudes into the battery housing section 16 of the first contact section 22 of the electrode terminal 20 provided near the inner periphery of the battery housing section 16. At this time, since the first contact section 22 is inclined at an inclination angle θ toward the side opposite the circuit board 11 (the downward side in FIG. 7), the outer periphery of the battery 17 slides smoothly along the inclination of the first contact section 22, and the battery 17 is housed in the battery housing section 16.

[0070] Also, at this time, the edge portion (upper edge portion in Figure 7) 22b of the tip portion 22a of the first contact portion 22 that faces the circuit board 11 is inclined toward the opposite side to the circuit board 11, and since the tip of the tip portion 22a is formed in a tapered shape, the outer periphery of the battery 17 abuts against the edge portion 22b of the tapered tip portion 22a of the first contact portion 22 from diagonally above.

[0071] At this time, with the first contact portion 22 tilted at an inclination angle θ toward the side opposite the circuit board 11 (downward in FIG. 7 ), the side portion 22b of the tip portion 22a is further tilted toward the side opposite the circuit board 11, and the outer periphery of the battery 17 slides more smoothly along this inclined side portion 22b, and the battery 17 is accommodated in the battery housing portion 16. Therefore, even if the tip portion 22a of the first contact portion 22 protrudes into the battery housing portion 16, the tip portion 22a of the first contact portion 22 does not get in the way, and the battery 17 can be easily and satisfactorily accommodated in the battery housing portion 16.

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

[0073] At this time, the battery 17 is pressed down inside the battery housing section 16 by the battery presser 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 the receiving section 24, eliminating the inclination of the receiving section 24 and, consequently, the inclination of the main body section 21 and the first contact section 22. In other words, the non-electrode surface 17c of the battery 17 presses down on the receiving section 24, eliminating the inclination of the receiving section 24 and making the receiving section 24 parallel to the bottom of the battery housing section 16.

[0074] As a result, the tilt of the main body 21 and the first contact portion 22 is eliminated, and the main body 21 and the first contact portion 22 return to their initial states. That is, when the main body 21 returns to its initial state in the state shown in Fig. 6, the second contact portion 23 is pressed against the circuit board 11 and is electrically connected stably to the circuit board 11, and the first contact portion 22 also returns to its initial state, and the tip of the tip portion 22a is pulled up to correspond to approximately the middle of the outer peripheral surface 17b of the battery 17 in the thickness direction (vertical direction), so that the tip of the tip portion 22a makes reliable and good contact with the outer peripheral surface 17b of the battery 17. As a result, the battery 17 is electrically connected to the circuit board 11 by the electrode terminal 20 and the battery retainer 18.

[0075] The watch module 6 is then installed inside the watch case 1. In this case, the dial 8 is placed on the solar panel 9 arranged on the top surface of the housing 10, and the outer periphery of the dial 8 is surrounded by the panel retaining member 35. At this time, the pointer 14b of the first watch movement 14 protrudes above the dial 8, and the function hand 15b of the second watch movement 15 protrudes above the dial 8. In this state, the hand 14a is attached to the pointer 14b of the first watch movement 14, and the function hand 15a is attached to the function hand 15b of the second watch movement 15. The watch module 6 is then installed inside the watch case 1, and the dial 8 is placed below the parting member 7.

[0076] At this time, the light-emitting unit 33 of the illumination device 30, which is located above the panel retaining member 35, is placed within the light-emitting unit storage portion 7b of the parting member 7 and positioned above the dial 8. This ensures that the watch module 6 is properly incorporated into the watch case 1. After this, the switch units 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, how to use such a wristwatch will be described. In this wristwatch, hands 14a are normally moved above dial 8 by first clock movement 14 to indicate the time, and function hands 15a are moved above dial 8 by second clock movement 15 to indicate the function. Information such as the time, day of the week, and date displayed on display panel 13 can be seen from above dial 8 through display windows 9a on the 3 o'clock and 6 o'clock sides of solar panel 9.

[0078] Furthermore, when using this wristwatch in a dark place such as at night, selecting the illumination mode 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 causes the light-emitting section 33 of the light-emitting member 31 of the illumination device 30 to emit light and illuminate the dial 8. That is, the light-emitting section 33 is positioned above the dial 8 by the mounting adjustment member 32 and is arranged within the light-emitting section 7b of the parting member 7, and because this light-emitting section 7b is open toward the dial 8, light emitted by the light-emitting section 33 is irradiated 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, making it possible to clearly see the time indication by the hands 14a, the function indication by the function hand 15a, and the information displayed by the display panel 13. In this case, the light-emitting housing portion 7b of the parting member 7 is open to the dial 8 side.

[0080] Therefore, even if the attachment adjustment member 32 can be seen from the inside of the watch case 1 through this open area, the attachment adjustment member 32 is colored in the same color family as the trim member 7 or in black, so that the attachment adjustment member 32 is difficult to see from the inside of the watch case 1, thereby improving the design.

[0081] Thus, this wristwatch lighting device 30 is equipped with an illuminating member 31 having a light-emitting unit 33 that illuminates the dial 8, which is the illuminated object provided on the top surface of the housing 10, and a pair of support legs 34 that are connection parts that support the light-emitting unit 33 and are provided from the underside of the housing to the light-emitting unit 33, and an attachment adjustment member 32 that holds the pair of support legs 34 and adjusts the installation state of the light-emitting unit 33 at a predetermined location on the outer periphery of the dial 8, and is positioned independent of the housing 10, thereby providing a product with excellent versatility.

[0082] In other words, in this wristwatch lighting device 30, the mounting adjustment member 32 that holds the light-emitting member 31 is independently positioned at a predetermined location on the housing 10 around the outer periphery of the dial 8, and 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, thereby providing a product with excellent versatility.

[0083] In this case, in the illumination device 30 of this wristwatch, the shape, size and height of the mounting adjustment member 32 are individually set according to the panel retaining member 35, which is an installation member that is installed on the outer periphery of the dial 8 and holds the dial 8. Therefore, even if the shape, size and height of the panel retaining member 35 differ depending on the model of wristwatch, for example, the mounting adjustment member 32 can be set to the optimal shape, size and height according to the panel retaining member 35, and the light-emitting unit 33 can be installed 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 pressing member 35. Therefore, even if, for example, other components such as a solar panel 9 are arranged below the dial 8 and the height of the dial 8 changes, the mounting adjustment member 32 can be arranged according to the height of the dial 8, and the height of the light-emitting section 33 of the light-emitting member 31 can be optimally set.

[0085] Furthermore, in the illumination 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 arranged below the dial 8, so that even if the shape, size, or height of the mounting adjustment member 32 is changed in accordance with the panel pressing member 35, the pair of support legs 34 can reliably and satisfactorily electrically connect the light-emitting unit 33 to the circuit board.

[0086] That is, 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, and the pair of support legs 34 pass through the pair of mounting holes 32a and protrude on the opposite side of the light-emitting part 33, and each of these protruding ends is bent to provide a bent portion 34a, so that the mounting adjustment member 32 can be attached to a predetermined location on the outer periphery of the dial 8 by each bent portion 34a of the pair of support legs 34, and the light-emitting part 31 can be held in place.

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

[0088] In this case, in the illumination device 30 of this wristwatch, even if other components such as a solar panel 9 are placed below the dial 8 and the height of the panel pressing member 35 changes, the mounting adjustment member 32 can be properly attached and securely fixed to a predetermined location on the outer periphery of the dial 8 by changing the bending position of each bending portion 34a of the pair of support legs 34.

[0089] Furthermore, in the lighting device 30 of this wristwatch, the mounting adjustment member 32 holds the light-emitting portion 33 of the light-emitting member 31 above the dial 8, so that even if the height of the dial 8 changes due to the panel holding member 35, the mounting adjustment member 32 can hold the light-emitting portion 33 above the dial 8, ensuring that the light emitted by the light-emitting portion 33 is irradiated onto the upper surface of the dial 8, thereby enabling the dial 8 to be well illuminated.

[0090] In the above-described embodiment, the lighting device 30 is described as being installed on the 5 o'clock side of the dial 8, but in this invention, it does not necessarily have to be installed on the 5 o'clock side, and it may be installed anywhere on the outer periphery of the dial 8.

[0091] Furthermore, in the above-described embodiment, the illumination device 30 illuminates the dial 8, but the present invention does not necessarily have to illuminate the dial 8, and may also illuminate, for example, the display panel 13. In this case, the illumination device 30 may be disposed on the outer periphery of the display panel 13.

[0092] Furthermore, although the above-described embodiment has been described as being applied to a wristwatch, the present invention does not necessarily have to be a wristwatch, and can be applied to various types of clocks, such as travel watches, alarm clocks, table clocks, wall clocks, etc. Furthermore, the present invention does not necessarily have to be a clock, and can be applied to various types of electronic devices, such as mobile phones and personal digital assistants.
