[0003] [Patent Document 1] JP 2006-266843 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the structure in which the light emitting member is positioned and fixed by bending the leads has the following problems.

This requires an additional step to return the bent leads to their original position during removal, and it is also necessary to be able to access the light-emitting component fixed to the case from both the top and bottom.

[0009] An embodiment of the present invention will be described with reference to FIGS. In addition, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0010] FIG. 1 is an exploded perspective view of the main parts of a timepiece 100 according to this embodiment, and FIG. 2 is a perspective view of the main case 2 of the timepiece 100 as viewed from the rear side. In the following description, the vertical direction (second direction) refers to the front-to-back direction (the front side is the top and the back side is the bottom) of the watch 100 (main case 2). The direction perpendicular to the central axis Ax of the watch 100 along the vertical direction is called the "radial direction," and the rotational direction around the central axis Ax is called the "circumferential direction."

[0011] As shown in Fig. 1, a timepiece 100 according to this embodiment is an example of a light source device according to the present invention, and is a wristwatch worn on a user's wrist. The timepiece 100 is equipped with a main body case 2 formed in a substantially cylindrical shape when viewed from the front. The main body case 2 is formed from a hard resin such as, but not limited to, ABS (Acrylonitrile Butadiene Styrene) resin.

[0012] The inside of the main case 2 houses a watch main body including a liquid crystal panel 31 and a light guide plate 32 . The liquid crystal panel 31 and the light guide plate 32 are both formed in a substantially circular plate shape and are arranged in this order from the front side. The liquid crystal panel 31 is arranged so as to be visible from the front side through a windshield member (not shown), and displays various information including the time. The light guide plate 32 is a backlight for the liquid crystal panel 31, and guides light from the light emitting member 4 described below to illuminate the liquid crystal panel 31 from the back side.

[0013] 2, light-emitting members 4 that illuminate the liquid crystal panel 31 through the light guide plate 32 are disposed on the inner side of the main body case 2. Although not particularly limited, the light-emitting members 4 are disposed at two locations on the side of the main body case 2 in the 3 o'clock direction, which are slightly spaced apart in the circumferential direction.

[0014] 3(a) and 3(b) are a perspective view and a front view of the light emitting member 4 disposed in the LED fixing portion 21 of the main body case 2. Fig. 4 is a perspective view of the light emitting member 4, and Fig. 5 is a perspective view of the LED fixing portion 21 of the main body case 2. As shown in these figures, the light emitting member 4 is an LED (light emitting diode) with lead terminals in this embodiment, and has a light emitting element 41 and two electrode members . The light emitting element 41 is sealed with resin and formed into a rectangular parallelepiped shape. With the light emitting surface 41a facing the inner diameter side of the main body case 2, the back surface opposite to the light emitting surface 41a of the light emitting element 41 is supported by an electrode member 42. With the light emitting member 4 disposed within the main body case 2, the light emitting surface 41a is disposed opposite to the incident surface of the light guide plate 32 (see FIG. 6(c)). In the following description, the directions are referred to as front, rear, left and right as viewed from the light emitting element 41 (light emitting surface 41a). In other words, the inner diameter direction of the main body case 2, which is the light emitting direction in which the light emitting surface 41a faces, is referred to as the "forward direction", the outer diameter direction, which is the opposite direction, is referred to as the "rearward direction", and the tangential direction to the circumferential direction of the main body case 2 is referred to as the "left and right direction".

[0015] The two electrode members 42 are each formed into a substantially L-shape in a side view, and are arranged side by side in a left-right direction (third direction) perpendicular to both the light emission direction and the second direction with their positions substantially aligned with each other in the front-rear direction and the up-down direction (second direction) perpendicular to the light emission direction. Specifically, each electrode member 42 has a support portion 43 and a terminal portion 44.

[0016] The support part 43 is attached to the rear surface of the light-emitting element 41 to support the light-emitting element 41. More specifically, the support part 43 is formed in a flat plate shape that is approximately vertical in the front-rear direction, and the light-emitting element 41 is attached to approximately the upper half of the support part 43. The terminal portion 44 is formed in a flat plate shape that is substantially perpendicular to the up-down direction, and extends rearward from the lower end of the support portion 43.

[0017] The main body case 2 is formed with an LED fixing portion 21 on which the light emitting member 4 is disposed. The LED fixing portion 21 is formed in a concave shape recessed from both the inner circumferential surface 2a and the lower end surface 2b of the main body case 2, and accommodates the light emitting member 4 inside the concave shape. Specifically, the LED fixing portion 21 has a front bottom surface 22 and a lower bottom surface 23. The front bottom surface 22 is formed in a flat surface that is approximately perpendicular to the front-rear direction. When the light emitting member 4 is placed on the LED fixing part 21, the front bottom surface 22 faces the rear surfaces of the support parts 43 of the electrode members 42 to restrict rearward movement of the light emitting member 4. The front bottom surface 22 is an example of a first restricting part according to the present invention. The lower bottom surface 23 is formed in a planar shape that is approximately perpendicular to the up-down direction, and extends rearward from the lower end of the front bottom surface 22. When the light emitting member 4 is placed on the LED fixing portion 21, the lower bottom surface 23 faces the upper surfaces of the terminal portions 44 of the electrode members 42.

[0018] When the light emitting member 4 is placed on the LED fixing portion 21, the inner side surfaces 24 on both the left and right sides of the front bottom surface 22 and the lower bottom surface 23 face the outer side surfaces 44a in the left-right direction (third direction) of each terminal portion 44 to restrict movement of the light emitting member 4 in the left-right direction (third direction). The inner side surfaces 24 are an example of a third restricting portion and a second opposing surface according to the present invention. The third restricting portion restricts movement of the light emitting member 4 in the left-right direction (third direction). In addition, each of the two inner sides 24 of the LED fixing part 21 is formed in a stepped shape having a stepped portion 24a. The inner side 24 is formed so that the width in the left-right direction of the LED fixing part 21 (i.e., the distance between the two inner sides 24) narrows stepwise across the stepped portion 24a toward the rear. The stepped portion 24a is chamfered so that the front and rear surfaces are smoothly connected to allow the light emitting member 4 to be smoothly inserted. In this embodiment, the stepped portion 24a is formed at a front-rear position that approximately coincides with the front bottom surface 22. Due to the stepped portion 24a, the light emitting member 4 can be easily inserted at the front opening (forward of the stepped portion 24a) of the LED fixing part 21, and the movement of the light emitting member 4 in the left-right direction is restricted as the light emitting member 4 is inserted rearward to the rear side of the stepped portion 24a.

[0019] Of the LED fixing part 21, an upper side surface 25 protruding forward from an upper portion of the front bottom surface 22 faces an upper end surface 43a of each support part 43 to restrict upward movement of the light emitting member 4 when the light emitting member 4 is placed on the LED fixing part 21. The upper side surface 25 is an example of a second restricting part and a first opposing surface according to the present invention. In addition, the upper side surface 25 of the LED fixing part 21 is formed in a stepped shape having a stepped portion 25a. The upper side surface 25 is formed so as to straddle the stepped portion 25a and stepwise position downward as it moves rearward. The stepped portion 25a is chamfered so that the rear surface is smoothly connected and the light emitting member 4 can be smoothly inserted. This stepped portion 25a makes it easy to insert the light emitting member 4 at the front opening (forward of the stepped portion 25a) of the LED fixing part 21, and as the light emitting member 4 is inserted rearward to the rear side of the stepped portion 25a, the upward movement of the light emitting member 4 is restricted. In addition, the upper portion of the LED fixing part 21 constituting the upper side surface 25 of the main body case 2 is cut out in a concave shape in the center in the left-right direction, and has a bottom surface that is approximately flush with the front bottom surface 22. In other words, the upper side surface 25 restricts the movement of the light emitting member 4 at two points on the left and right. This cutout portion is shaped to allow the escape of a gripping member that grips the light emitting member 4 when attaching or detaching the light emitting member 4 to or from the LED fixing part 21.

[0020] Moreover, the LED fixing part 21 has a first rib 26 and a second rib 27 protruding from the front bottom surface 22 and the lower bottom surface 23. The first rib 26 and the second rib 27 are disposed approximately in the center of the LED fixing part 21 in the left-right direction (third direction), and are located between two electrode members 42 arranged side by side in the left-right direction when the light emitting member 4 is disposed on the LED fixing part 21. Among these, the first rib 26 is provided protruding from the lower part of the front bottom surface 22. The first rib 26 protrudes forward from the front bottom surface 22 and protrudes downward from the lower bottom surface 23. When the light emitting member 4 is placed on the LED fixing part 21, the upper surface 26a of the first rib 26 faces the lower surface 43b of the support part 43 to restrict the downward movement of the light emitting member 4. The upper surface 26a of the first rib 26 is an example of a second restricting part according to the present invention. The second restricting part restricts the movement of the light emitting member 4 in the up-down direction (second direction). More specifically, the lower surface 43b of the support part 43 is located on the center side of the light emitting member 4 in the left-right direction, but since it is formed on only one of the two electrode members 42, it is mainly formed on one side of the center of the light emitting member 4 in the left-right direction. In addition, the lower surface 43b of the support part 43 is located slightly below the light emitting element 41. The second rib 27 protrudes from the lower bottom surface 23 rearward of the first rib 26. The second rib 27 has approximately the same width in the left-right direction as the first rib 26. The position of the rear end of the second rib 27 approximately coincides with the position of the rear end of the terminal portion 44 when the light emitting member 4 is placed on the LED fixing portion 21. In addition, instead of (or in addition to) the inner side surfaces 24 on both the left and right sides of the LED fixing portion 21, the left and right side surfaces 26b, 27b (third restricting portion) of the first rib 26 and the second rib 27 may restrict the left-right movement of the light emitting member 4. That is, from the LED fixing portion 21 toward the front, at least one of the left side surfaces 26b, 27b and the right inner side surface 24 (third restricting portion) of the first rib 26 and the second rib 27 may restrict the rightward movement of the light emitting member 4, and at least one of the right side surfaces 26b, 27b (third restricting portion) and the left inner side surface 24 (third restricting portion) of the first rib 26 and the second rib 27 may restrict the leftward movement of the electrode member 42 of the light emitting member 4. In this case, the upper surface 26a of the first rib 26 is a second restricting portion that restricts movement in the second direction (up-down direction), and the side surface 26b is a third restricting portion that restricts movement in the third direction (left-right direction). Therefore, the first rib 26 alone can function as both the second restricting portion and the third restricting portion, so that at least the first rib 26 is required to be provided, and the second rib 27 does not have to be provided. Alternatively, the first rib 26 may be a protrusion including a second regulating portion that regulates movement in the second direction (up-down direction), and the second rib 27 may be a protrusion including a third regulating portion that regulates movement in the third direction (left-right direction). Moreover, the terminal portion 44 of the LED and the substrate (not shown) are connected by an interconnect (not shown) made of a metal wire covered with resin or rubber. To pass this interconnect through, a gap is provided between the first rib 26 and the second rib 27, and the interconnect passes through this gap. The widths of the first rib 26 and the second rib 27 in the third direction (left-right direction) are approximately the same. In this embodiment, the first rib 26 and the second rib 27 are provided, but the present invention is not limited to this configuration. If another connecting member such as a spring is used instead of the interconnect, one rib may be sufficient and there may be no gap. In other words, the first rib 26 and the second rib 27 may be integrally formed. Furthermore, the rib may be divided into front and rear and / or left and right.

[0021] Next, a procedure for attaching the light emitting member 4 to the LED fixing portion 21 of the main body case 2 will be described. FIG. 6 is a diagram for explaining a procedure for attaching the light emitting member 4 to the LED fixing portion 21. As shown in FIG.

[0022] As shown in FIG. 6( a ), first, the worker attaches the double-sided tape 5 to the front bottom surface 22 of the LED fixing portion 21 of the main body case 2 . Next, while holding the light emitting member 4 vertically with a jig or the like, the worker inserts it into the LED fixing portion 21 from the front (the inner diameter side of the main body case 2) along the terminal portion 44 and fits it in.

[0023] 6(b), the rear surface of the support part 43 is fixed to the front bottom surface 22 of the LED fixing part by the double-sided tape 5. In this way, the front bottom surface 22 faces the rear of the support part 43, and the rearward movement of the light emitting member 4 is restricted.

[0024] At this time, the light emitting member 4 is inserted into the LED fixing portion 21 while being appropriately guided left and right by the left and right inner side surfaces 24 of the LED fixing portion 21, which are formed in a stepped shape (see FIG. 3). When the light emitting member 4 is fully inserted, the movement of the light emitting member 4 in the left and right direction is restricted by the inner side surface 24 of the LED fixing portion 21, which faces the side surface 44a of the terminal portion 44. That is, the movement of the electrode member 42 in the third direction (left and right direction) perpendicular to both the light emission direction and the second direction (up and down direction) is restricted by the inner side surface 24 (third restriction portion) of the LED fixing portion 21. That is, the light emitting member 4 is positioned in the left and right direction. Similarly, the light emitting member 4 is inserted into the LED fixing portion 21 while being appropriately guided by the upper side surface 25 of the LED fixing portion 21 formed in a stepped shape. When the light emitting member 4 is fully inserted, the upper side surface 25 of the LED fixing portion 21 facing the upper end surface 43a of the support portion 43 restricts the upward movement of the light emitting member 4. When the light emitting member 4 is fully inserted, the upper surface 26a of the first rib 26 of the LED fixing portion 21 facing the lower surface 43b of the support portion 43 restricts the downward movement of the light emitting member 4. That is, the upper side surface 25 of the LED fixing portion 21 and the upper surface 26a of the first rib 26 position the light emitting member 4 in the up-down direction. That is, the upper side surface 25 of the LED fixing portion 21 and the upper surface 26a of the first rib 26 restrict the movement of the electrode member 42 in the second direction (up-down direction) perpendicular to the light emission direction. In this manner, the light emitting member 4 is positioned relative to the LED fixing portion 21 with its movement in the up-down and left-right directions restricted.

[0025] Next, as shown in FIG. 6(c), the worker places the light guide plate 32 in front of the light emitting surface 41a of the light emitting element 41 so as to face it. This restricts forward movement of the light emitting member 4. In other words, the light emitting member 4 is positioned in the front-rear direction by the front bottom surface 22 of the LED fixing portion and the light guide plate 32.

[0026] As described above, according to this embodiment, the terminal portion 44 of the electrode member 42 extends rearward (in the opposite direction to the light emitting direction of the light emitting element 41) from the support portion 43 that supports the light emitting element 41. In addition, the upper side surface 25 of the LED fixing portion 21 and the upper surface 26a of the first rib 26 restrict vertical movement relative to the electrode member 42 (support portion 43). The inner side surface 24 of the LED fixing portion 21 restricts horizontal movement relative to the electrode member 42 (terminal portion 44). As a result, by inserting the light emitting member 4 into the LED fixing portion 21 from the front (light emitting direction side) along the terminal portion 44, the light emitting member 4 is positioned in the vertical direction by the upper side surface 25 and the first rib 26 of the LED fixing portion 21, and is positioned in the horizontal direction by the inner side surface 24 of the LED fixing portion 21. Therefore, unlike conventional light emitting members that are inserted into a case member and then fixed by bending the terminal portion, the light emitting member 4 can be fixed to the main body case 2 without bending the terminal portion 44. In other words, when removing the light emitting member 4 fixed to the main body case 2, it is sufficient to simply pull out the light emitting member 4 to the inner diameter side of the main body case 2 without the need to return the bent terminal portion to its original state as in the conventional case. In addition, in this case, it is sufficient to grasp the light emitting member 4 from the inner diameter side of the main body case 2, and structural constraints can be reduced compared to the conventional structure in which it was necessary to access the light emitting member (terminal portion) fixed to the case member from two places. Furthermore, since the light emitting member 4 is positioned by the arrangement of each surface of the main body case 2 (LED fixing portion 21) and the light guide plate 32, the light emitting member 4 can be positioned with higher accuracy than in the past when it was positioned by the bending position of the terminal portion. Therefore, the light emitting member 4 can be fixed in a suitable manner.

[0027] Furthermore, according to this embodiment, the upper side surface 25 of the LED fixing portion 21 is formed in a stepped shape that is gradually positioned downward toward the rear. As a result, when the light emitting member 4 is placed in the LED fixing portion 21 from the front, the light emitting member 4 can be easily inserted through the front opening of the LED fixing portion 21, and as the light emitting member 4 is inserted toward the rear, the upward movement of the light emitting member 4 is suitably restricted.

[0028] In addition, according to this embodiment, the front bottom surface 22 of the LED fixing portion 21 faces the rear side of the support portion 43 to restrict movement toward the rear side, and the light guide plate 32 faces the light emitting surface 41a (the front surface of the light emitting element 41). As a result, the light emitting member 4 is positioned in the front-rear direction by the front bottom surface 22 of the LED fixing portion 21 and the light guide plate 32. Therefore, the light emitting member 4 can be fixed even more suitably.

[0029] Furthermore, according to this embodiment, the inner surface 24 of the LED fixing portion 21 is formed in a stepped shape that protrudes in stages toward the rear. As a result, when the light emitting member 4 is placed in the LED fixing portion 21 from the front, the light emitting member 4 can be easily inserted through the front opening of the LED fixing portion 21, and as the light emitting member 4 is inserted toward the rear, movement of the light emitting member 4 in the left-right direction is suitably restricted.

[0030] Furthermore, according to this embodiment, the light guide plate 32 that guides the light from the light emitting element 41 faces the light emitting surface 41a of the light emitting element 41, and restricts the light emitting member 4 from moving forward. This makes it possible to restrict the forward movement of the light emitting member 4 without using any other restricting member solely for restricting the movement of the light emitting member 4.

[0031] Incidentally, the embodiments to which the present invention can be applied are not limited to the above-described embodiments, and it goes without saying that various modifications are possible without departing from the gist of the present invention.

[0032] For example, in the above embodiment, the upper side surface 25 of the LED fixing part 21 is formed in a stepped shape having a chamfered stepped portion 25a. However, this stepped portion 25a (chamfer) may be formed on the edge of the front end of the upper side surface 25 (corner with the inner peripheral surface 2a of the main body case 2). Similarly, the stepped portions 24a (chamfer) may be formed on the edge of the front end of the inner side surface 24 on both the left and right sides of the LED fixing part 21 (corner with the inner peripheral surface 2a of the main body case 2). Furthermore, each of the upper side surface 25 and both inner side surfaces 24 of the LED fixing part 21 may be formed as an inclined surface that gradually narrows toward the rear, rather than being formed in a stepped shape having the stepped portions 24a, 25a.

[0033] Furthermore, in the above embodiment, the terminal portions (leads) 44 of the electrode members 42 are bent backward, but they may be bent forward depending on, for example, the connection structure with the substrate. Furthermore, the bending angle of the terminal portion 44 does not have to be vertical (90°), and may be within a range that can be regarded as substantially vertical (e.g., ±5°) or within a range that does not impede the insertion of the light emitting member 4 into the LED fixing portion 21 (e.g., less than 90°). In this case, the lower bottom surface 23 of the LED fixing portion 21 facing the terminal portion 44 may also be formed into an inclined surface corresponding to the bending angle of the terminal portion 44.

[0034] In the above embodiment, a timepiece (wristwatch) has been described as an example of the light source device according to the present invention. However, the light source device according to the present invention is not limited to timepieces (or devices mounted on timepieces), and can be suitably applied to various devices and structures to which a light-emitting member having a terminal portion is fixed. Furthermore, the light emitting element according to the present invention is not limited to a light emitting diode (LED). [Explanation of symbols]
