The pressing plate 12 is disposed in approximately half of the area of ​​the housing 10, extending from a 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 pressing plate 12 is configured such 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 pressing 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, the display panel 13 is a flat display element such as a liquid crystal display element or an EL (electroluminescence) display element, is formed in a substantially rectangular shape, and is disposed diagonally across the 3 o'clock and 6 o'clock sides of the housing 10. The display panel 13 is supported on the circuit board 11 in a state in which it is electrically connected to the circuit board 11 by an interconnector 13a. In this case, the solar panel 9 is configured such that, as shown in FIG. 3, display windows 9a are provided at two locations, on the 3 o'clock side and the 6 o'clock side, and information displayed on the display panel 13 can be seen through each of these display windows 9a.

[0018] As shown in Fig. 5, the first clock movement 14 includes a first step motor and a first gear train mechanism, and is provided in approximately the center of the housing 10. As shown in Fig. 3, the first clock movement 14 is configured such that a pointer 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 the protruding pointer 14b, and the hand 14a is moved above the dial 8.

[0019] As shown in Fig. 5, the second clock 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 clock 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, so that the function hand 15a is moved above the dial 8.

[0020] 4 to 6, battery storage section 16 is formed in a circular recess shape 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 a battery pressing section 18 that presses battery 17 stored therein and electrically connects electrode surface 17a, which is the negative pole of battery 17, to circuit board 11, and an 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 to the housing 10, and extends 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 at its middle portion with multiple contact pieces 18a 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, the battery pressing portion 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, the battery pressing portion 18 is configured so that when the battery hook portion 18b is engaged with the locking portion 10b on the 12 o'clock side of the housing, the battery pressing portion 18 presses 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 held near the inner periphery of the battery housing section 16, and a first contact portion 22 provided on a side of the main body 21 and in contact with an 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 provided at one end portion (upper end portion in FIG. 7) of the main body 21 on the circuit board 11 side, against which the circuit board 11 is pressed, and a receiving portion 24 provided at the other end portion (lower end portion in FIG. 7) of the main body 21 opposite the circuit board 11, against which a non-electrode surface 17c opposite the electrode surface 17a of the battery 17 is pressed.

[0024] 7, this electrode terminal 20 is formed by bending a conductive metal plate such as stainless steel, by pressing or sheet metal processing, etc., to integrally form 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 a vertical flat plate shape, 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 from 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 on the inner side of 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 includes three holding walls 25a to 25c.

[0026] Of these three holding walls 25a to 25c, two holding walls 25a and 25b are provided on the inner periphery of the battery housing section 16, as shown in Figures 5 and 6. The remaining holding wall 25c is provided on the outer side of the battery housing section 16 with its semicylindrical protrusion corresponding to the space between the two holding walls 25a and 25b. Thus, the holding section 25 is configured to hold the main body section 21 by sandwiching it between the two holding walls 25a and 25b and the one holding wall 25c in a tiltable state.

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

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

[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 the open portion.

[0030] 5 and 7, 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 the same direction as the first contact portion 22 and in a direction gradually moving away from the first contact portion 22, and is formed to extend at an angle toward the circuit board 11 (upper side in FIG. 7). As a result, the second contact portion 23 is configured so that the obliquely extending tip portion 23a protrudes from the housing 10 toward the circuit board 11 side, and an electrode (not shown) of the circuit board 11 is 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 disposed on the lower surface of the housing 10 (the upper surface in Figure 6) and attached with 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 configured to be inclined at an inclination angle θ while being clamped by the holding portion 25 of the housing 10, and to incline the first contact portion 22 at the inclination angle θ toward the side opposite the circuit board 11 (the lower side in Figure 7) in accordance with the inclination of the main body portion 21.

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

[0033] As a result, as shown in Figure 5, when the electrode terminal 20 is in the initial state before the circuit board 11 is attached to the housing 10, the main body portion 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 portion 18 in the state shown in Figure 6, with the second contact portion 23 pressed against the circuit board 11, the receiving portion 24 is pressed by the non-electrode surface 17c of the battery 17, eliminating the inclination of the receiving portion 24, and as a result, the inclinations of the main body portion 21 and the first contact portion 22 are also eliminated.

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

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

[0038] Meanwhile, 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 2 and 3. As shown in Figures 9 and 10, this illumination device 30 is equipped with a light-emitting member 31 that illuminates the upper 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 a chip shape having 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 a strip shape from a conductive metal. Each of the pair of support legs 34 is disposed on the back surface of the light emitting unit 33, and is 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 length of the light emitting unit 33 and the vertical length of 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 made of insulating synthetic resin and has a substantially rectangular plate shape. The 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 and place it in an independent state while holding a pair of support legs 34. In this case, a pair of mounting holes 32a into which the pair of support legs 34 are respectively inserted are provided penetrating the mounting adjustment member 32 from top to bottom. The pair of mounting holes 32a are each formed to have the same cross-sectional shape as the pair of support legs 34.

[0042] 3 and 9, the attachment adjustment member 32 is configured to be placed at a predetermined location on a ring-shaped panel retaining member 35, which is an installation member that presses down the upper surface of the outer periphery of the solar panel 9 that is placed under the dial 8. That is, the shape, size, height, color, etc. of the attachment adjustment member 32 are set according to the panel retaining member 35, whose shape, size, height, etc. differ depending on the model of the wristwatch. As a result, the attachment adjustment member 32 is formed to be placed as a separate part in an attachment 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, 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 so as 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 range wider than the attachment adjustment member 32. A pair of insertion holes 10c into which a 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 protrude downward, and when the mounting adjustment member 32 is placed in the mounting storage portion 35a of the panel pressing member 35, the lower ends protruding downward from the pair of insertion holes 10c are bent, and each of the bent folded 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 as to position the light emitting portion 33 above the dial 8.

[0047] 9, a pair of connecting members 37 are disposed within the cutout portion 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) of the circuit board 11 corresponding to the cutout portion 36 of the housing 10, and the other end of each of the pair of connecting members 37 is configured to elastically contact each of the bent portions 34a of the 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 the pair of support legs 34, as shown in Fig. 9. In this case, the mounting member 38 is formed in a rectangular plate shape. The mounting member 38 is provided with a pair of holding holes 38a that hold the pair of connecting members 37, penetrating vertically. 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 pressing member 35 has a light-emitting storage section 7b in which the light-emitting unit 33 is arranged, which is open to the inside of the wristwatch case 1. As a result, the lighting device 30 is configured such that light emitted by the light-emitting unit 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 towards 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, so that the attachment adjustment member 32 can be seen from inside the watch case 1 through this open section. For this reason, it is desirable that the attachment adjustment member 32 is 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 together with the packing 4a to the upper opening of the watch case 1 located above the parting member 7.

[0052] Then, the watch module 6 is fitted inside the wristwatch 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 fitted to the housing 10. That is, the display panel 13 is placed in a location ranging from the 3 o'clock side to the 6 o'clock side of the housing 10. In addition, 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 upper surface of housing 10, and each of display window portions 9a on the 3 o'clock and 6 o'clock sides of solar panel 9 is aligned with 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 above notch portion 36 provided on the 5 o'clock side of housing 10.

[0054] This makes it possible to install the lighting device 30. For this purpose, 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 on 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 and protrude downward. This allows the light emitting member 31 to be attached to the mounting adjustment member 32. In this state, the mounting adjustment member 32 is placed in the mounting storage section 35a of the panel pressing member 35 as a separate part. In this case, the shape, size, height, color, etc. of the mounting adjustment member 32 are set according to the panel pressing member 35, whose shape, size, height, etc. differ 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 retaining member 35, so as to 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 each of 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 disposed above the panel holding member 35, and the pair of connecting members 37 can be disposed below each of 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 with the lighting device 30 disposed in the mounting storage portion 35a of the panel holding 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 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 a terminal storage portion 26 provided on the inner periphery of the battery storage 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 storage portion 16, and this extended tip portion 22a is bent radially toward the inside of the battery storage portion 16, and the tip of this bent tip portion 22a protrudes from the terminal storage portion 26 into the battery storage portion 16.

[0060] Also, at this time, 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 portion (upper end portion 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 being disposed protruding 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 inside 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 inside 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 inside the battery housing portion 16.

[0062] This state is the initial state of the electrode terminal 20. In other words, 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 disposed in the terminal storage portion 26 without tilting. In addition, the second contact portion 23 is disposed inclined from the housing 10 toward the circuit board 11 side, with the tip portion 23a protruding from the housing 10 toward the circuit board 11 side, and the receiving portion 24 is disposed 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 connection members 37 for electrically connecting the lighting device 30 to the circuit board 11 is held in advance in a pair of holding holes 38a of a mounting member 38, and the pair of connection members 37 are placed in the cutout portions 36 of the housing 10 by the mounting member 38 so as to 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 ends of the pair of connecting members 37 elastically contact a pair of electrodes (not shown) of the circuit board 11, and the other ends elastically contact 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, 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 as to bend toward the housing 10 side (the lower side in FIG. 7), as shown in Fig. 6. As a result, the main body portion 21 is inclined at an inclination angle θ while being sandwiched between the holding portion 25 of the housing 10, and in conjunction with this inclination of the main body portion 21, the first contact portion 22 is inclined at an inclination angle θ toward the side opposite the circuit board 11 side, and the receiving portion 24 is also inclined in the same direction at the same inclination angle θ.

[0066] Then, a metal pressing plate 12 is placed and attached to the underside of the circuit board 11. At this time, the pressing plate 12 is placed in approximately half of the area of ​​the housing 10, extending from an approximate straight line connecting the 3 o'clock side and the 9 o'clock side of the circuit board 11 to the 6 o'clock side, and hook portions 12a provided at multiple points on the outer periphery of the pressing plate 12 are engaged with locking projections 10a provided on the outer periphery of the housing 10. As a result, the pressing plate 12 presses the circuit board 11 against the housing 10, and the circuit board 11 is attached to the housing 10.

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

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

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

[0070] Also, at this time, the side portion (upper side 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 side opposite the circuit board 11, and the tip of the tip portion 22a is formed in a tapered shape, so that the outer periphery of the battery 17 abuts against the side 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 inclined at the inclination angle θ toward the side opposite the circuit board 11 (the downward side in FIG. 7), the side portion 22b of the tip portion 22a is further inclined toward the side opposite the circuit board 11, and the outer periphery of the battery 17 slides even more smoothly along this inclined side 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 can be easily and satisfactorily stored in the battery storage 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, with the contact piece 18a of the battery retaining portion 18 in contact with the electrode surface 17a of the battery 17, the battery retaining portion 18 presses the battery 17 into the battery storage portion 16.

[0073] At this time, the battery 17 is pressed down inside the battery housing section 16 by the battery pressing section 18, so that with the second contact section 23 pressed against the circuit board 11, the receiving section 24 is pressed down by the non-electrode surface 17c of the battery 17, eliminating the inclination of the receiving section 24 and, accordingly, eliminating the inclination of the main body section 21 and the first contact section 22. In other words, the receiving section 24 is pressed down by the non-electrode surface 17c of the battery 17, 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] Therefore, the inclinations between 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 states. That is, when the main body 21 returns to its initial state in the state shown in Fig. 6, the first contact portion 22 also returns to its initial state with the second contact portion 23 pressed against the circuit board 11 and electrically connected stably to the circuit board 11, and the tip of the tip portion 22a is pulled up so that the tip of the tip portion 22a reliably and satisfactorily contacts the outer peripheral surface 17b of the battery 17, corresponding to approximately the middle portion in the thickness direction (vertical direction) of 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 pressing portion 18.

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

[0076] At this time, the light-emitting section 33 of the illumination device 30, which is arranged above the panel retaining member 35, is placed within the light-emitting storage section 7b of the parting member 7 and arranged above the dial 8. This allows the watch module 6 to be properly incorporated into the wristwatch case 1. After this, the switch sections 3 are attached to the 2 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock sides of the wristwatch case 1, and the back cover 5 is attached to the bottom of the wristwatch case 1 together with the waterproof ring 5a. This completes the assembly of the wristwatch.

[0077] Next, how to use such a wristwatch will be described. In this wristwatch, normally, a hand 14a is moved above the dial 8 by a first clock movement 14 to indicate the time, and a function hand 15a is moved above the dial 8 by a second clock 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 can be seen from above the dial 8 through display windows 9a on the 3 o'clock and 6 o'clock sides of the solar panel 9.

[0078] Furthermore, when this wristwatch is used in a dark place such as at night, selecting an illumination mode by operating any of the multiple switch sections 3 on the 2 o'clock, 4 o'clock, 8 o'clock, or 10 o'clock side 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 disposed within the light-emitting storage section 7b of the parting member 7 while being positioned above the dial 8 by the mounting adjustment member 32, and since this light-emitting storage section 7b is open to the dial 8 side, the light emitted by the light-emitting section 33 is irradiated onto the upper surface of the dial 8 from this open position.

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

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

[0081] In this way, the electrode terminal 20 of this wristwatch comprises a main body portion 21 that is held on the peripheral portion of the battery storage section 16 that stores the battery 17, a first contact portion 22 that is provided on this main body portion 21 and contacts the outer peripheral surface 17b of the battery 17 stored in the battery storage section 16, and a second contact portion 23 that is provided from the main body portion 21 toward the circuit board 11 that is arranged on one side outside the battery storage section 16 and is pressed against the circuit board 11 to tilt the first contact portion 22 together with the main body portion 21 toward the opposite side to the circuit board 11, thereby improving the ease of storing the battery 17.

[0082] That is, with electrode terminal 20 of this wristwatch, even if tip 22a of first contact portion 22 protrudes into battery storage portion 16 when battery 17 is stored in battery storage portion 16, first contact portion 22 is inclined toward the side away from circuit board 11, so that even if the outer periphery of battery 17 abuts against tip 22a of first contact portion 22, the outer periphery of battery 17 can slide smoothly along the inclination of first contact portion 22. As a result, tip 22a of first contact portion 22 does not get in the way, and battery 17 can be stored easily and satisfactorily in battery storage portion 16, improving the ease of storing battery 17.

[0083] In this case, in the electrode terminal 20 of this wristwatch, the first contact portion 22 is arranged along the inner surface of the battery storage section 16, so that even if the outer periphery of the battery 17 abuts against the tip portion 22a of the first contact portion 22, the first contact portion 22 arranged along the inner surface of the battery storage section 16 allows the outer periphery of the battery 17 to slide smoothly, allowing the battery 17 to be easily and securely stored in the battery storage section 16.

[0084] Furthermore, in this electrode terminal 20, the main body portion 21 is clamped and held in a tiltable manner by a holding portion 25 provided on the peripheral portion of the battery storage section 16, so that when the second contact portion 23 is pressed against the circuit board 11, the main body portion 21 held by the holding portion 25 can be easily tilted, and thus the first contact portion 22 can be tilted favorably toward the opposite side to the circuit board 11.

[0085] In other words, the holding portion 25 has three holding walls 25a-25c that hold the main body portion 21 at three points, and of these three holding walls 25a-25c, two holding walls 25a, 25b are arranged on the inside side of the battery storage portion 16 at the periphery of the battery storage portion 16, and the other holding wall portion 25c has a semicylindrical protrusion and is arranged on the outside side of the battery storage portion 16 with this protrusion facing between the two holding walls 25a, 25b, so that the main body portion 21 can be well sandwiched and held between the two holding walls 25a, 25b and the one holding wall portion 25c in a tiltable state.

[0086] In addition, in this electrode terminal 20, the first contact portion 22 extends from the side of the main body portion 21 along the inner surface of the battery storage portion 16, and this extended tip portion 22a contacts the outer surface 17b of the battery 17, and the second contact portion 23 extends from one end of the main body portion 21 on the circuit board 11 side in a direction gradually moving away from the first contact portion 22 in approximately the same direction as the first contact portion 22, and this extended tip portion 23a is pressed against the circuit board 11, so that the second contact portion 23, which is pressed against the circuit board 11 and pressed toward the battery storage portion 16, can be used to tilt the first contact portion 22 together with the main body portion 21 toward the opposite side to the circuit board 11.

[0087] Furthermore, in this electrode terminal 20, tip 22a of first contact portion 22 is formed in a tapered shape with side portion 22b facing circuit board 11 inclined toward the side opposite circuit board 11, so that when tip 22a of first contact portion 22 protruding into battery storage portion 16 is inclined toward the side opposite circuit board 11, side portion 22b of tip 22a can be further inclined toward the side opposite circuit board 11.

[0088] As a result, with this electrode terminal 20, even if the outer periphery of the battery 17 abuts against the tip 22a of the first contact portion 22 when the battery 17 is stored in the battery storage section 16, the outer periphery of the battery 17 can slide even more smoothly along the further inclination of the side portion 22b of the tip 22a with the tip 22a of the first contact portion 22 in a tilted state, thereby allowing the battery 17 to be stored well in the battery storage section 16.

[0089] In addition, in this electrode terminal 20, a receiving portion 24 is provided at the other end of the main body portion 21 opposite the circuit board 11, against which the non-electrode surface 17c, one side of the battery 17 stored in the battery storage portion 16, is pressed. Therefore, when the second contact portion 23 is pressed against the circuit board 11 and the first contact portion 22 is tilted together with the main body portion 21 toward the opposite side to the circuit board 11, the receiving portion 24 also tilts in the same direction, and when the battery 17 stored in the battery storage portion 16 is pressed against the receiving portion 24 in this state, the tilt of the receiving portion 24 is eliminated, and the tilts of the main body portion 21 and the first contact portion 22 can be eliminated.

[0090] In other words, with this electrode terminal 20, when the battery 17 is stored in the battery storage section 16 and the non-electrode surface 17c of the battery 17 is pressed against it, the second contact portion 23 is pressed against the circuit board 11, and the inclination of the receiving portion 24 is eliminated, and the inclination between the main body portion 21 and the first contact portion 22 is eliminated accordingly. Therefore, even if the main body portion 21 and the first contact portion 22 are inclined toward the opposite side to the circuit board 11 before the battery 17 is stored in the battery storage section 16, the inclination of the inclined main body portion 21 and the first contact portion 22 can be eliminated.

[0091] Therefore, in this electrode terminal 20, when the second contact portion 23 is pressed against the circuit board 11, the inclinations of the main body portion 21 and the first contact portion 22 are eliminated, and the second contact portion 23 returns to the state before it was pressed against the circuit board 11, that is, the initial state in which the main body portion 21 is held by the holding portion 25, and therefore the first contact portion 22 also returns to its initial state, so that the tip of the tip portion 22a can be pulled up.

[0092] As a result, the electrode terminal 20 can be positioned approximately in the middle in the thickness direction of the outer peripheral surface 17b, which is the positive pole of the battery 17 stored in the battery storage section 16, so that the tip of the tip portion 22a can be reliably and satisfactorily contacted with the outer peripheral surface 17b of the battery 17. This allows for a reliable and satisfactorily electrical connection between the outer peripheral surface 17b, which is the positive pole of the battery 17, and the circuit board 11.

[0093] Furthermore, with the watch module 6 of this wristwatch, even if the tip 22a of the first contact portion 22 of the electrode terminal 20 protrudes into the battery storage portion 16 when the battery 17 is stored in the battery storage portion 16, the first contact portion 22 is inclined away from the circuit board 11, so that even if the outer periphery of the battery 17 abuts against the tip 22a of the first contact portion 22, the outer periphery of the battery 17 can be smoothly slid along the inclination of the first contact portion 22. As a result, the tip 22a of the first contact portion 22 does not get in the way, and the battery 17 can be stored easily and satisfactorily in the battery storage portion 16, improving the workability of storing the battery 17.

[0094] In this case, this watch module 6 is provided with a battery pressing portion 18 that contacts the electrode surface 17a, which is the other surface opposite the non-electrode surface 17c of the battery 17 stored in the battery storage section 16, thereby pressing the battery 17 into the battery storage section 16 and electrically connecting the battery 17 to the circuit board 11. This battery pressing portion 18 allows the battery 17 to be securely pressed down within the battery storage section 16 for proper storage, and also ensures a secure and good electrical connection between the electrode surface 17a, which is the negative pole of the battery 17, and the circuit board 11.

[0095] Therefore, in this watch module 6, the battery 17 can be pressed and stored within the battery storage section 16 by the battery pressing portion 18, so that the non-electrode surface 17c of the battery 17 can be reliably pressed against the receiving portion 24 of the electrode terminal 20, reliably eliminating the inclination of the receiving portion 24, and with the second contact portion 23 pressed against the circuit board 11, the tip portion 22a of the first contact portion 22 can be brought into good contact with the outer peripheral surface 17b, which is the positive pole of the battery 17, thereby reliably connecting the outer peripheral surface 17b, which is the positive pole of the battery 17, and the circuit board 11.

[0096] Furthermore, in this watch module 6, the battery storage section 16 is provided on the peripheral portion of the housing 10, and the first contact portion 22 is provided away from the center of the housing 10 toward the peripheral portion of the housing 10. Therefore, even if the display panel 13, first clock movement 14, second clock movement 15, etc. are incorporated in the housing 10, the battery storage section 16 and the first contact portion 22 can be provided well in the housing 10 so as not to interfere with these elements.

[0097] In the above embodiment, the lighting device 30 is provided on the 5 o'clock side of the dial 8, but in the present invention, it does not necessarily have to be provided on the 5 o'clock side, and the lighting device may be provided anywhere on the outer periphery of the dial 8.

[0098] In the above embodiment, the illumination device 30 illuminates the dial 8, but the present invention does not necessarily have to illuminate the dial 8, and may 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.

[0099] Furthermore, in the above embodiment, the present invention has been described as being applied to a wristwatch, but this 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, this 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.
