[0010] As shown in FIGS. 1 to 4, this watch case 1 includes a main body case 4, a first exterior case 5, and a second exterior case 6. The main body case 4 is made of a synthetic resin containing carbon fiber or glass fiber in a highly rigid polyamide resin, and is formed to be lightweight and highly strong. A metal reinforcing member 4a is embedded in the side wall of the main body case 4. A part of this reinforcing member 4a protrudes into the inside of the main body case 4. Note that the main body case 4 is not limited to a synthetic resin and may be formed of metal.

[0011] As shown in FIGS. 1 to 4, the first exterior case 5 is formed of a highly rigid metal such as stainless steel or a titanium alloy, and is formed to be disposed so as to cover the upper outer surface of the main body case 4. The second exterior case 6 is formed of an elastic synthetic resin such as urethane resin. This second exterior case 6 is configured to be attached to the outer peripheral portion of the main body case 4 by pressing the leg portion 5a of the first exterior case 5 with the first exterior case 5 exposed.

[0012] Further, as shown in FIGS. 1 and 4, a watch glass 7 is attached to the upper opening of the watch case 1, that is, the upper opening of the main body case 4, via a glass packing 7a. A back cover 8 is attached to the lower part of the watch case 1, that is, the lower part of the main body case 4, by a plurality of screws 8b via a waterproof ring 8a.

[0013] Furthermore, inside this wristwatch case 1, as shown in FIG. 4, a clock module 9 is provided. This clock module 9 includes, although not shown in the figures, a clock movement that drives the hands to indicate the time, a display unit that electro-optically displays various information such as time, date, and day of the week, a circuit unit that electrically controls these, and a rechargeable battery that supplies power to this circuit unit, and various other components necessary for the clock function.

[0014] In this case, as shown in FIGS. 3 to 6, the back cover 8 is formed of a highly rigid metal such as stainless steel or titanium alloy. The back cover 8 is formed in a substantially square plate shape with the 3 o'clock side and the 9 o'clock side protruding in an arc shape. In the central part of the back surface (the lower surface in FIG. 4), the central part protrudes toward the back surface side, and a sensor housing part 10 is recessed and provided on the inner surface (the upper surface in FIG. 4) of this protruding central part.

[0015] As shown in FIGS. 4 to 6, a pulse sensor 11 is provided in this sensor housing part 10. In this case, a circular opening 12 is provided so as to penetrate vertically through the bottom of the sensor housing part 10. The opening 12 has a small-diameter hole 12a on the inner side of the sensor housing part 10 and a large-diameter hole 12b on the lower surface side, which is the back surface side of the back cover 8, provided on the same axis. A protective glass 13 is fitted into the large-diameter hole 12b of the opening 12.

[0016] As shown in FIGS. 4 and 5, the pulse sensor 11 includes a sensor substrate 14 and a sensor part 15. The sensor substrate 14 is disposed at the bottom inside the sensor housing part 10 and is electrically connected to a circuit unit (not shown) of the clock module 9. The sensor part 15 includes a light-emitting element and a light-receiving element (both not shown), is provided on the lower surface of the sensor substrate 14, and is disposed inside the small-diameter hole 12a of the opening 12.

[0017] As a result, as shown in FIG. 4, in the pulse sensor 11, the light emitted by the light emitting element of the sensor unit 15 is irradiated onto the blood vessels in the arm skin through the protective glass 13, and the reflected light of the irradiated light is received by the light receiving element of the sensor unit 15 through the protective glass 13. Based on the change in the amount of received light of the received light, it is configured to detect the pulse.

[0018] By the way, as shown in FIGS. 3 to 5, a component mounting member 16 is provided in the watch case 1. As shown in FIGS. 6 and 7, this component mounting member 16 includes a back cover 8 which is a base member, a terminal mounting member 17 which is a mounting member attached to the upper surface which is the inner surface on the 6 o'clock side of the back cover 8, a plurality of charging terminals 18 attached to the terminal mounting member 17, and a reinforcing plate 19 for reinforcing the terminal mounting member 17.

[0019] In this case, as shown in FIGS. 6 and 7, on the 6 o'clock side of the back cover 8, a mounting hole 20 for arranging the terminal mounting member 17 is provided so as to penetrate from the upper surface to the lower surface which is the outer surface (back surface). This mounting hole 20 is a substantially rectangular through hole having a long length from the 5 o'clock side to the 7 o'clock side, and the four corners are formed in a shape curved in an arc shape. As a result, the mounting hole 20 is formed in a shape that is substantially elliptical. This mounting hole 20 includes a small diameter hole portion 20a on the upper surface side (inner surface side) of the back cover 8 and a large diameter hole portion 20b on the lower surface side (outer surface side) of the back cover 8.

[0020] As shown in FIGS. 6 and 7, the terminal mounting member 17 is formed of a non-metallic material having insulation properties, for example, synthetic resin. This terminal mounting member 17 includes a main body portion 21 to which a plurality of charging terminals 18 are attached, and a flange portion 22 provided on the outer peripheral portion of the main body portion 21. The main body portion 21 is configured to be arranged in the mounting hole 20 of the back cover 8.

[0021] That is, as shown in FIGS. 6 and 7, the main body portion 21 is formed in a substantially rectangular shape whose outer shape is the same as the shape of the inner peripheral surface of the small-diameter hole portion 20a in the mounting hole 20 of the back cover 8. Further, the main body portion 21 is formed such that its thickness in the vertical direction is thicker than the length (depth) in the vertical direction of the mounting hole 20 of the back cover 8 and is substantially the same thickness as the thickness in the vertical direction on the 6 o'clock side of the back cover 8. A plurality of through holes 21a for attaching a plurality of charging terminals 18 are provided at equal intervals along the longitudinal direction of the main body portion 21.

[0022] As shown in FIGS. 6 and 7, the flange portion 22 is formed in a substantially rectangular shape whose outer shape is larger than the shape of the inner peripheral surface of the large-diameter hole portion 20b in the mounting hole 20 of the back cover 8. The flange portion 22 is provided on the outer peripheral portion of the main body portion 21 such that when the lower portion of the main body portion 21 is disposed in the small-diameter hole portion 20a and the large-diameter hole portion 20b of the mounting hole 20 of the back cover 8, the lower surface of the flange portion 22 is disposed on the counterbore surface of the counterbore portion 8d provided on the upper surface of the back cover 8.

[0023] Further, as shown in FIGS. 6 and 7, the flange portion 22 is formed such that its thickness in the vertical direction is about 1 / 3 of the thickness of the main body portion 21 in the vertical direction, and the upper portion of the main body portion 21 protrudes upward from the upper surface of the flange portion 22. In this case, first insertion holes 22a into which a plurality of screw members 23 are inserted are provided at the four corners of the flange portion 22, respectively.

[0024] As shown in FIGS. 6 to 8, each of the plurality of charging terminals 18 is formed in a substantially round bar shape to be inserted into a plurality of through holes 21a provided in the main body portion 21 of the terminal attachment member 17. That is, the plurality of charging terminals 18 are formed such that their outer diameters are substantially the same as the inner diameters of the through holes 21a of the main body portion 21 and their lengths in the vertical direction are longer than the length (thickness) of the main body portion 21 in the vertical direction.

[0025] In this case, as shown in FIGS. 7 and 8, at each lower end portion of the plurality of charging terminals 18, there are provided retaining heads 18a having a large outer diameter. For this reason, at the lower portion of the through hole 21a of the main body portion 21, a large-diameter hole portion 21b into which the head 18a is inserted is formed. Further, at each upper end portion of the plurality of charging terminals 18, retaining grooves 18b are provided in an annular shape, and a retaining member 24 such as an E-ring is attached to the retaining groove 18b.

[0026] Thus, as shown in FIGS. 7(a) and 7(b), the plurality of charging terminals 18 are inserted into the plurality of through holes 21a provided in the main body portion 21 from the lower side, and when each head 18a is disposed in each large-diameter hole portion 21b of each through hole 21a, the retaining grooves 18b at each upper end portion are exposed on the upper side of the main body portion 21, and the retaining members 24 are respectively attached to the exposed retaining grooves 18b.

[0027] For this reason, as shown in FIGS. 7(a) and 7(b), the heads 18a at each lower end portion of the plurality of charging terminals 18 are exposed on the lower surface side, which is the outer surface of the back cover 8, from the mounting holes 20 of the back cover 8, and each upper end portion is exposed on the upper surface side, which is the inner surface side of the back cover 8, and in this state, they are configured not to come out in the vertical direction from within each through hole 21a of the main body portion 21.

[0028] In this case, as shown in FIGS. 6 to 8, at each upper end portion of the plurality of charging terminals 18, there are respectively provided small-diameter connection protrusions 18c that are electrically connected to a circuit portion (not shown) of the timepiece module 9 in the wristwatch case 1. Further, on each outer peripheral surface of the plurality of charging terminals 18, a plurality of waterproof grooves 18d are respectively provided in an annular shape.

[0029] As shown in FIGS. 7 and 8, waterproof rings 25 are respectively provided in the plurality of waterproof grooves 18d. The plurality of waterproof rings 25 are configured such that the portions exposed from the waterproof grooves 18d are in pressure contact with the inner peripheral surfaces of the plurality of through holes 21a of the main body portion 21 to achieve waterproofing between the outer peripheral surface of the charging terminal 18 and the inner peripheral surfaces of the plurality of through holes 21a of the main body portion 21.

[0030] On the one hand, as shown in FIGS. 6 and 7, the reinforcing plate 19 is formed in a frame shape having the same shape as the flange portion 22 of the terminal attachment member 17 from a highly rigid metal such as stainless steel. The reinforcing plate 19 is formed such that the thickness in the vertical direction is substantially the same as the length (height) in the vertical direction of the main body portion 21 protruding upward from the upper surface of the flange portion 22. Further, at the four corners of the reinforcing plate 19, second insertion holes 19a into which a plurality of screw members 23 are inserted are provided coaxially corresponding to a plurality of first insertion holes 22a provided in the flange portion 22 of the terminal attachment member 17, respectively.

[0031] In this case, as shown in FIG. 6, on the counterbore surface of the counterbore portion 8d on the upper surface of the back cover 8, a plurality of screw holes 8e into which a plurality of screw members 23 are screwed are provided coaxially corresponding to the plurality of first insertion holes 22a of the flange portion 22 of the terminal attachment member 17 and the plurality of second insertion holes 19a of the reinforcing plate 19, respectively. These plurality of screw holes 8e do not penetrate through the back cover 8 vertically and are provided only on the upper surface side of the back cover 8.

[0032] Thereby, as shown in FIG. 6, the reinforcing plate 19 is configured such that when a plurality of screw members 23 are inserted into the plurality of second insertion holes 19a from the inner surface side of the back cover 8, that is, from above, and the inserted plurality of screw members 23 are screwed into the respective screw holes 8e of the back cover 8 through the respective first insertion holes 22a of the flange portion 22 of the terminal attachment member 17, the flange portion 22 is pressed against the upper surface of the back cover 8 for attachment.

[0033] That is, as shown in FIGS. 6 and 7, when the plurality of screw members 23 are screwed into the respective screw holes 8e of the back cover 8 and tightened, the reinforcing plate 19 presses the flange portion 22 of the synthetic resin terminal attachment member 17 evenly against the counterbore surface of the counterbore portion 8d of the back cover 8 with the entire lower surface of the reinforcing plate 19, preventing partial deformation of the terminal attachment member 17 and configuring the terminal attachment member 17 to be securely and firmly fixed to the inner surface of the back cover 8.

[0034] As a result, as shown in FIGS. 6 and 7, even if the flange portion 22 of the terminal attachment member 17 is formed of a synthetic resin having insulation properties, the reinforcing plate 19 evenly presses the flange portion 22 over the entire lower surface of the reinforcing plate 19. Therefore, the plurality of screw members 23 are not partially pressed against and bitten into the flange portion 22, and the structure is configured to prevent damage to the flange portion 22 by the plurality of screw members 23.

[0035] In this case, as shown in FIGS. 6 to 8, a packing groove 26 is provided on the counterbore surface of the counterbore portion 8d on the upper surface of the back cover 8 so as to surround the main body portion 21 of the terminal attachment member 17. That is, the packing groove 26 is provided in a substantially rectangular annular shape along the peripheral edge of the small-diameter hole portion 20a in the mounting hole 20 of the back cover 8. In this case, the packing groove 26 is provided at a position closer to the peripheral edge of the mounting hole 20 than the plurality of screw holes 8e, avoiding the plurality of screw holes 8e provided on the counterbore surface of the counterbore portion 8d on the upper surface of the back cover 8.

[0036] As shown in FIGS. 8(a) and 8(b), a waterproof packing 27 is fitted into the packing groove 26. The waterproof packing 27 has a D-shaped cross-sectional shape, that is, the bottom surface disposed at the bottom of the packing groove 26 is formed in a flat surface, and the upper surface is formed in an arc shape protruding from the packing groove 26.

[0037] As shown in FIGS. 8(a) and 8(b), in a state where the waterproof packing 27 is disposed in the packing groove 26, when the reinforcing plate 19 is tightened by the plurality of screw members 23, the arc-shaped upper surface of the waterproof packing 27 protruding from the packing groove 26 is pressed by the flange portion 22 of the terminal attachment member 17 and is configured to be pushed into the packing groove 26.

[0038] As a result, as shown in FIGS. 6 to 8, the waterproof packing 27 is configured to achieve waterproofing between the upper surface of the back cover 8, that is, the counterbore surface of the counterbore portion 8d of the back cover 8, and the lower surface of the flange portion 22 of the terminal mounting member 17. In this case, the waterproof packing 27 is configured such that even if the outer shape of the packing groove 26 is substantially rectangular and the four corners are formed in an arc shape, and the waterproof packing 27 is arranged at the four arc-shaped corners, it can surely and satisfactorily achieve waterproofing between the upper surface of the back cover 8, that is, the counterbore surface of the counterbore portion 8d of the back cover 8, and the lower surface of the flange portion 22 of the terminal mounting member 17.

[0039] By the way, as shown in FIGS. 9 and 10, this component mounting member 16 is configured such that a charging device 30 for charging a rechargeable battery (not shown) of the clock module 9 is connected thereto. That is, this charging device 30 is of an alligator clip type and includes a device main body 31 and a pressing portion 32, and these are rotatably connected by a holding shaft 33.

[0040] As shown in FIGS. 9 and 10, the device main body 31 includes a connection portion 34 connected to the component mounting member 16 of the back cover 8. This connection portion 34 includes a position restricting portion 35 into which, except for the main body portion 21 of the terminal mounting member 17, is inserted into the large-diameter hole portion 20b of the mounting hole 20 of the back cover 8, and a plurality of electrode terminals 36 provided in the position restricting portion 35 and each in contact with and electrically connected to a plurality of charging terminals 18 of the component mounting member 16.

[0041] In this case, as shown in FIGS. 9 and 10, the position restricting portion 35 is provided to protrude from the inside of the device main body 31 to the outside, and a frame-shaped protrusion 35a is provided at the protruding tip portion. The outer peripheral surface of this frame-shaped protrusion 35a has the same shape as the inner peripheral surface of the large-diameter hole portion 20b in the mounting hole 20 of the back cover 8, and the inner peripheral surface of the frame-shaped protrusion 35a is formed in the same shape as the outer peripheral surface of the lower side of the main body portion 21 of the terminal mounting member 17.

[0042] As a result, as shown in FIGS. 9 and 10, when the frame-shaped protrusion 35a at the tip is inserted into the large-diameter hole portion 20b in the mounting hole 20 of the back cover 8, the frame-shaped protrusion 35a is sandwiched between the inner peripheral surface of the large-diameter hole portion 20b in the mounting hole 20 of the back cover 8 and the outer peripheral surface of the lower side in the main body portion 21 of the terminal mounting member 17, and the apparatus main body 31 is configured to be positioned with respect to the back cover 8.

[0043] As shown in FIGS. 9 and 10, the plurality of electrode terminals 36 are provided in a state of being embedded inside the position regulating portion 35 corresponding to the plurality of charging terminals 18 of the component mounting member 16, and each tip portion protrudes into the frame-shaped protrusion 35a of the position regulating portion 35 and is exposed. As a result, when the frame-shaped protrusion 35a of the position regulating portion 35 is inserted into the large-diameter hole portion 20b in the mounting hole 20 of the back cover 8, the plurality of electrode terminals 36 are configured to be respectively pressed against the lower surfaces of the heads 18a of the lower ends of the plurality of charging terminals 18 of the component mounting member 16.

[0044] In this case, as shown in FIGS. 9 and 10, the plurality of electrode terminals 36 are respectively connected to an A / C conversion unit (not shown) in the apparatus main body 31 via lead wires 36a. Further, a power cord 37 is connected to this A / C conversion unit. As a result, the plurality of electrode terminals 36 are configured such that the power from the power cord 37 is converted and supplied by the A / C conversion unit, and the supplied power is supplied to the plurality of charging terminals 18 of the component mounting member 16.

[0045] On the other hand, as shown in FIGS. 9 and 10, the pressing portion 32 of the charging device 30 presses and sandwiches the wristwatch case 1 against the apparatus main body 31, and is rotatably attached to the apparatus main body 31 by a holding shaft 33. A lever portion 32a is provided at the end of the pressing portion 32 on the holding shaft 33 side so as to protrude to the right side of the holding shaft 33 in FIG. 9.

[0046] In this case, as shown in FIGS. 9 and 10, the pressing portion 32 is biased in a direction of rotating toward the apparatus main body 31 by a spring member 38 provided on the holding shaft 33. This spring member 38 is a torsion coil spring provided on the outer periphery of the holding shaft 33, with one end portion 38a locked to the pressing portion 32 and the other end portion 38b locked to the apparatus main body 31.

[0047] Accordingly, as shown in FIGS. 9 and 10, when the charging device 30 presses the lever portion 32a of the pressing portion 32 against the spring force of the spring member 38, the pressing portion 32 rotates in a direction away from the apparatus main body 31, widening the space between the apparatus main body 31 and the pressing portion 32. In this state, the wristwatch case 1 is configured to be disposed between the apparatus main body 31 and the pressing portion 32.

[0048] Also, as shown in FIGS. 9 and 10, when the wristwatch case 1 is disposed between the apparatus main body 31 and the pressing portion 32, the pressing portion 32 rotates about the holding shaft 33 by the spring force of the spring member 38 and presses the wristwatch case 1 against the apparatus main body 31, pressing the plurality of electrode terminals 36 against the plurality of charging terminals 18 of the component mounting member 16. In this state, the charging device 30 is configured to charge a rechargeable battery (not shown) of the timepiece module 9 incorporated in the wristwatch case 1.

[0049] Next, a case of assembling the component mounting member 16 in such a wristwatch will be described. In this case, first, a plurality of charging terminals 18 are attached to the terminal attachment member 17. At this time, waterproof rings 25 are respectively attached to a plurality of waterproof grooves 18d provided on the outer peripheral surfaces of the plurality of charging terminals 18 in advance. In this state, the plurality of charging terminals 18 are inserted into a plurality of through holes 21a provided in the main body portion 21 of the terminal attachment member 17 from below.

[0050] At this time, each head portion 18a of the plurality of charging terminals 18 is disposed within a large-diameter hole portion 21b provided at the lower end portion of each through-hole 21a of the main body portion 21. As a result, the connection protrusions 18c at the upper end portions of the plurality of charging terminals 18 protrude above the main body portion 21, and the retaining grooves 18b of the plurality of charging terminals 18 are exposed above the main body portion 21. In this state, a retaining member 24 is attached to each retaining groove 18b of the plurality of charging terminals 18. Thereby, the plurality of charging terminals 18 cannot come out in the vertical direction from the respective through-holes 21a of the main body portion 21 and are attached to the main body portion 21.

[0051] Then, the terminal attachment member 17 to which the plurality of charging terminals 18 are attached is attached to an attachment hole 20 provided on the 6 o'clock side of the back cover 8. At this time, a waterproof packing 27 is disposed in advance in a packing groove 26 provided in a countersunk portion 8d on the upper surface of the back cover 8. That is, the waterproof packing 27 has a D-shaped cross-sectional shape, that is, the bottom surface is formed in a flat surface and the upper surface is formed in an arc shape. When the waterproof packing 27 is disposed in the packing groove 26, the bottom surface of the waterproof packing 27 is disposed at the bottom of the packing groove 26, and the arc-shaped upper surface protrudes from within the packing groove 26.

[0052] In this state, the main body portion 21 of the terminal attachment member 17 is inserted into the small-diameter hole portion 20a of the attachment hole 20 of the back cover 8 from the upper surface side (inner surface side) of the back cover 8, and a flange portion 22 provided on the outer peripheral portion of the main body portion 21 is disposed on the arc-shaped upper surface of the waterproof packing 27 protruding from the countersunk surface of the countersunk portion 8d provided on the upper surface of the back cover 8. For this reason, the flange portion 22 is disposed in a state slightly floating from the countersunk surface of the countersunk portion 8d of the back cover 8.

[0053] At this time, the lower portion of the main body portion 21 is disposed in a slightly floating state within the large-diameter hole portion 20b of the attachment hole 20 of the back cover 8, and the upper portion of the main body portion 21 protrudes above the flange portion 22. Also, at this time, a plurality of first insertion holes 22a provided at the four corners of the flange portion 22 are coaxially corresponding to a plurality of screw holes 8e provided at the four corners of the countersunk portion 8d of the back cover 8.

[0054] In this state, the reinforcing plate 19 is placed on the flange portion 22, and a plurality of second insertion holes 19a provided at the four corners of the reinforcing plate 19 are made to correspond coaxially with a plurality of first insertion holes 22a provided at the four corners of the flange portion 22 and a plurality of screw holes 8e provided at the four corners of the counterbore portion 8d of the back cover 8. Then, a plurality of screw members 23 are inserted into the respective second insertion holes 19a of the reinforcing plate 19 from above the reinforcing plate 19, that is, from above the upper surface side of the back cover 8. Each of these inserted screw members 23 is inserted into the respective first insertion holes 22a of the flange portion 22 and screwed into the plurality of screw holes 8e provided in the counterbore portion 8d of the back cover 8 and tightened.

[0055] Then, in response to the tightening of the plurality of screw members 23, the reinforcing plate 19 presses the flange portion 22 of the terminal mounting member 17 against the counterbore surface of the counterbore portion 8d of the back cover 8. At this time, since the flange portion 22 of the synthetic resin terminal mounting member 17 is pressed evenly against the counterbore surface of the counterbore portion 8d of the back cover 8 by the entire lower surface of the reinforcing plate 19, partial deformation of the terminal mounting member 17 is prevented, and the terminal mounting member 17 is firmly and securely fixed to the inner surface of the back cover 8.

[0056] Therefore, even if the flange portion 22 of the terminal mounting member 17 is formed of synthetic resin having insulating properties, since the entire lower surface of the reinforcing plate 19 presses the flange portion 22 evenly, the plurality of screw members 23 do not press the flange portion 22 partially. As a result, the plurality of screw members 23 do not bite into the flange portion 22, so that damage to the flange portion 22 by the plurality of screw members 23 can be prevented.

[0057] At this time, the lower surface of the flange portion 22 presses the arc-shaped upper surface of the waterproof packing 27 protruding from the counterbore surface of the counterbore portion 8d of the back cover 8 and presses it into the packing groove 26. For this reason, the lower surface of the flange portion 22 is pressed against and adhered to the counterbore surface of the counterbore portion 8d of the back cover 8, and the lower part of the main body portion 21 is disposed at an appropriate position within the large-diameter hole portion 20b of the mounting hole 20 of the back cover 8. Thereby, the component mounting member 16 is attached to the back cover 8.

[0058] Also, at this time, the pulse sensor 11 is arranged in the sensor housing portion 10 provided at the central portion of the back cover 8. In this case, a protective glass 13 is fitted in advance into the large-diameter hole 12b of the opening 12 of the back cover 8. In this state, the sensor portion 15 provided on the sensor substrate 14 of the pulse sensor 11 is arranged in the small-diameter hole 12a of the opening 12 of the back cover 8, and the sensor substrate 14 is arranged and fixed in the sensor housing portion 10. Thereby, the pulse sensor 11 is attached to the back cover 8.

[0059] Then, the clock module 9 is incorporated into the wristwatch case 1, and the back cover 8 is attached to the lower portion of the wristwatch case 1 together with the waterproof ring 8a. At this time, each connection protrusion 18c of the plurality of charging terminals 18 of the component mounting member 16 is electrically connected to a circuit portion (not shown) of the clock module 9, and the sensor substrate 14 of the pulse sensor 11 is electrically connected to a circuit portion (not shown) of the clock module 9. Thereby, a wristwatch that can be charged by the charging device 30 is assembled.

[0060] Next, the case where this wristwatch is charged by the charging device 30 will be described. In this case, the lever portion 32a of the pressing portion 32 of the charging device 30 is pressed against the spring force of the spring member 38. Then, the pressing portion 32 rotates in a direction away from the device main body 31, and the space between the device main body 31 and the pressing portion 32 becomes wider. In this state, the wristwatch case 1 is arranged between the device main body 31 and the pressing portion 32.

[0061] At this time, the frame-shaped protrusion 35a of the position regulating portion 35 provided to protrude from the inside of the device main body 31 to the outside is made to correspond to the large-diameter hole portion 20b of the mounting hole 20 of the back cover 8. In this state, the pressing portion 32 rotates about the holding shaft 33 by the spring force of the spring member 38 and presses the wristwatch case 1 against the device main body 31. Then, the frame-shaped protrusion 35a of the position regulating portion 35 is inserted into the large-diameter hole portion 20b of the mounting hole 20 of the back cover 8.

[0062] In this case, the frame-shaped protrusion 35a is sandwiched between the inner peripheral surface of the large-diameter hole portion 20b in the mounting hole 20 of the back cover 8 and the outer peripheral surface on the lower side in the main body portion 21 of the terminal mounting member 17, and the device main body 31 is positioned with respect to the back cover 8. Then, the tip of each of the plurality of electrode terminals 36 embedded inside the position regulating portion 35 is respectively pressed against the lower surface of the head 18a at the lower end of each of the plurality of charging terminals 18 of the component mounting member 16.

[0063] As a result, the plurality of electrode terminals 36 of the charging device 30 are electrically connected to the plurality of charging terminals 18 of the component mounting member 16. At this time, since the plurality of electrode terminals 36 are respectively connected to an A / C conversion unit (not shown) in the device main body 31 by lead wires 36a, the power from the power cord 37 is converted and supplied by the A / C conversion unit, and the supplied power is supplied to the plurality of charging terminals 18 of the component mounting member 16, and a rechargeable battery (not shown) of the clock module 9 incorporated in the wristwatch case 1 is charged.

[0064] As described above, according to the component mounting member 16 of this wristwatch, the back cover 8, which is a base member having the mounting hole 20 provided therein and having rigidity to be attached to the wristwatch case 1, the terminal mounting member 17, which is inserted into the mounting hole 20 of the back cover 8 and attached to the upper surface, which is the inner surface of the back cover 8 located on the inner side of the wristwatch case 1, and the plurality of charging terminals 18 provided on the terminal mounting member 17 and exposed on the upper surface and the lower surface, which is the outer surface opposite to the upper surface of the back cover 8, are provided, whereby the wristwatch case 1 can be made thinner and smaller.

[0065] That is, in the component mounting member 16 of this wristwatch, since the terminal mounting member 17 is formed of an insulating material, insulation between the plurality of charging terminals 18 and the back cover 8 can be achieved, and in order to ensure the strength of the terminal mounting member 17, even if the thickness of the terminal mounting member 17 in the vertical direction is formed thick, since the terminal mounting member 17 is attached to the upper surface, which is the inner surface of the back cover 8, the thickness of the back cover 8 formed of a rigid material in the vertical direction can be made thin, whereby the entire wristwatch case 1 can be made thinner and smaller.

[0066] In this case, in the component mounting member 16 of this wristwatch, the back cover 8 which is the base member is formed of a metal with high rigidity, and the terminal mounting member 17 is formed of a non-metallic material having insulation properties, for example, synthetic resin. Therefore, even if the thickness of the back cover 8 is made thin, the strength of the back cover 8 can be ensured, and thus the entire thickness of the wristwatch case 1 can be reduced. Further, since the terminal mounting member 17 is formed of a non-metallic material having insulation properties, insulation between the plurality of charging terminals 18 and the back cover 8 can be surely and satisfactorily achieved, and thereby an electrically highly reliable product can be provided.

[0067] Also, in the component mounting member 16 of this wristwatch, the terminal mounting member 17 includes a main body portion 21 disposed in the mounting hole 20 of the back cover 8 to which the plurality of charging terminals 18 are attached, and a flange portion 22 provided on the outer peripheral portion of the main body portion 21 and disposed on the upper surface which is the inner surface of the back cover 8. By this, the vertical thickness of the main body portion 21 disposed in the mounting hole 20 of the back cover 8 can be formed sufficiently thick, whereby the plurality of charging terminals 18 can be surely and satisfactorily attached, and the main body portion 21 can be surely and satisfactorily attached to the back cover 8 by the flange portion 22.

[0068] Also, in the component mounting member 16 of this wristwatch, the flange portion 22 of the terminal mounting member 17 is attached to the upper surface which is the inner surface of the back cover 8 by a plurality of screw members 23 via a reinforcing plate 19 disposed on the flange portion 22. By this, even if the flange portion 22 is formed of synthetic resin having insulation properties and the vertical thickness of the flange portion 22 is thin, the flange portion 22 can be reinforced by the reinforcing plate 19, and thus the flange portion 22 can be surely and firmly attached to the upper surface of the back cover 8 by the plurality of screw members 23.

[0069] That is, in the component mounting member 16 of this wristwatch, when a plurality of screw members 23 are screwed into and tightened in a plurality of screw holes 8e of the back cover 8, the entire lower surface of the reinforcing plate 19 can uniformly press against the flange portion 22 of the synthetic resin terminal mounting member 17 on the counterbored surface of the counterbored portion 8d on the upper surface of the back cover 8 by surface contact. Thus, partial deformation of the terminal mounting member 17 can be prevented, and the terminal mounting member 17 can be securely and firmly fixed to the inner surface of the back cover 8. In this case, even if the flange portion 22 of the terminal mounting member 17 is formed of a synthetic resin having insulation properties, the plurality of screw members 23 do not partially bite into the flange portion 22, so that damage to the flange portion 22 caused by the plurality of screw members 23 can be prevented.

[0070] Also, in the component mounting member 16 of this wristwatch, a packing groove 26 in which a waterproof packing 27 is disposed is provided at the peripheral edge of the mounting hole 20 on the upper surface of the back cover 8. Since the waterproof packing 27 is pressed into the packing groove 26 by the flange portion 22 of the terminal mounting member 17, reliable and good waterproofing can be achieved between the upper surface of the back cover 8 and the lower surface of the flange portion 22 of the terminal mounting member 17. That is, even if the flange portion 22 of the terminal mounting member 17 is formed of a synthetic resin having insulation properties, since it is reliably pressed against the upper surface of the back cover 8 by the reinforcing plate 19, the waterproof packing 27 can be reliably pressed into the packing groove 26 by the flange portion 22.

[0071] In this case, the waterproof packing 27 has a D-shaped cross-sectional shape, that is, the bottom surface disposed at the bottom of the packing groove 26 is formed in a plane, and the upper surface protruding from the packing groove 26 is formed in an arc shape. Thus, when the flange portion 22 of the terminal mounting member 17 is pressed against in a state where the waterproof packing 27 is disposed in the packing groove 26, the arc-shaped upper surface of the waterproof packing 27 protruding from the packing groove 26 can be reliably pressed by the flange portion 22 and pushed into the packing groove 26. Therefore, reliable and good waterproofing can be achieved between the upper surface of the back cover 8 and the lower surface of the flange portion 22 of the terminal mounting member 17.

[0072] In the above-described embodiment, the case where the terminal mounting member 17 is formed of a synthetic resin having insulating properties has been described. However, the present invention is not limited to this, and for example, it may be formed of a non-metallic material such as ceramics having insulating properties.

[0073] Also, in the above-described embodiment, the case where the terminal is the charging terminal 18 has been described. However, the present invention does not necessarily have to be the charging terminal 18, and any terminal may be used as long as it is a connecting terminal such as a communication terminal.

[0074] Also, in the above-described embodiment, the case of applying to a wristwatch has been described. However, the present invention does not necessarily have to be a wristwatch, and it can be applied to various timepieces such as travel watches, alarm clocks, table clocks, and wall clocks.

[0075] Furthermore, the present invention does not necessarily have to be a timepiece, and it can also be applied to electronic devices such as mobile phones and portable information terminals. In this case, in the above-described embodiment, the case where the base member is the back cover 8 has been described. However, the present invention does not necessarily have to be the back cover 8, and any member can be used as long as it can be attached to the case.
