The tip 74a of the leg portion 74 faces the first mounting surface 51 of the substrate 23 and comes into contact with the first mounting surface 51. The tip 74a may be separated from the first mounting surface 51.

As shown in FIG. 8, the first holding portion 61 has two first claws 80. Hereinafter, the two first claws 80 may be individually referred to as the first claws 80A and 80B. The description common to the two first claws 80A and 80B is described as a description of the first claw 80.

The two first claws 80 project in the + Z direction from both ends of the flange 73 in the Y direction. Two tubular portions 71 are located between the two first claws 80. Therefore, the two light sources 55 housed in the two insertion holes 75 are surrounded by the two first claws 80.

The two first claws 80 each have two first pillar portions 81 and a first engaging portion 82. The first pillar portion 81 is separated from each other in the X direction and protrudes from the flange 73 in the + Z direction. The first engaging portion 82 extends in the X direction between the tip of one first pillar portion 81 and the tip of the other first pillar portion 81.

The two first claws 80 can be elastically deformed so that the first pillar portion 81 is elastically deformed so as to approach or move away from each other. Further, the first claw 80 is provided with a first engaging hole 85 formed (defined, partitioned) by two first pillar portions 81, a first engaging portion 82, and a flange 73.

The shape of the first claw 80A and the shape of the first claw 80B are different from each other. In the present embodiment, the distance between the two first pillars 81 in the first claw 80A is shorter than the distance between the two first pillars 81 in the first claw 80B.

Due to the above difference, the shape of the first engaging hole 85 of the first claw 80A and the shape of the first engaging hole 85 of the first claw 80B are also different from each other. The first engaging hole 85 of the first claw 80A is an example of the first engaging portion. The first engaging hole 85 of the first claw 80B is an example of the second engaging portion. The first claw 80 is not limited to this example.

The first holding portion 61 holds the substrate 23. In the present embodiment, the convex portion 53b of the substrate 23 is fitted into the first engaging hole 85 of the first claw 80A. Further, the convex portion 53c is fitted into the first engaging hole 85 of the first claw 80B. As a result, the holder 24 is attached to the substrate 23 by the first claw 80. Further, a part of the two first pillar portions 81 of the first claw 80 may be fitted into the two notches 53a of the substrate 23.

The convex portion 53b of the substrate 23 can be engaged with the first engaging hole 85 of the first claw 80A. Further, the convex portion 53c of the substrate 23 can be fitted into the first engaging hole 85 of the first claw 80B, but cannot be engaged with the first engaging hole 85 of the first claw 80A. .. The convex portion 53b of the substrate 23 may be able to engage with the first engaging hole 85 of the first claw 80B.

For example, in the X direction, the width of the convex portion 53c of the substrate 23 is the same as or smaller than the width of the first engaging hole 85 of the first claw 80B, but the width of the first engaging hole of the first claw 80A. It is larger than the width of 85. The convex portions 53b and 53c and the first engaging hole 85 are not limited to this example.

As shown in FIG. 6, when the first holding portion 61 holds the substrate 23, the light source 55 is accommodated in the insertion hole 75. The light source 55 and the end surface 22a of the light guide pipe 22 fitted in the insertion hole 75 face each other. That is, the first holding portion 61 of the holder 24 holds the substrate 23 so that the end surface 22a of the light guide pipe 22 and the light source 55 face each other.

As shown in FIG. 7, the second holding portion 62 has two second claws 90. The second claw 90 is an example of a wall. The two second claws 90 project in the −Z direction from both ends of the flange 73 in the X direction. Two tubular portions 71 are located between the two second claws 90. Therefore, the two light guide pipes 22 fitted in the two tubular portions 71 are surrounded by the two second claws 90.

The two second claws 90 each have two second pillar portions 91 and a second engaging portion 92. The second pillar portion 91 is separated from each other in the Y direction and protrudes from the flange 73 in the −Z direction. The second engaging portion 92 extends in the Y direction between the tip of one second pillar portion 91 and the tip of the other second pillar portion 91.

The two second claws 90 can be elastically deformed so that the second pillar portion 91 is elastically deformed so as to approach or move away from each other. Further, the second claw 90 is provided with a second engaging hole 95 formed (defined, partitioned) by two second pillar portions 91, a second engaging portion 92, and a flange 73.

As shown in FIG. 6, a guide surface 92a is provided on the second engaging portion 92. The guide surface 92a faces the two light guide pipes 22 fitted in the two tubular portions 71, and narrows as it approaches the light source 55 in the Z direction. In other words, the distance between the guide surfaces 92a of the two second claws 90 becomes shorter as it approaches the light source 55 in the Z direction. The guide surface 92a is not limited to this example.

In the X direction, the width of the guide surface 92a is larger than the width of the second inner peripheral surface 71d of the tubular portion 71. The width of the guide surface 92a in the X direction is the position closest to the other second claw 90 of the guide surface 92a and the position farthest from the other second claw 90 of the guide surface 92a in the X direction. The distance between. The width of the guide surface 92a in the X direction is also the distance in the X direction between the position closest to the light source 55 in the Z direction and the position farthest from the light source 55 in the Z direction. The width of the second inner peripheral surface 71d in the X direction is the difference between the maximum radius and the minimum radius of the second inner peripheral surface 71d.

The inclination angle of the guide surface 92a with respect to the central axis Ax of the insertion hole 75 is smaller than the inclination angle of the first inclined surface 71da with respect to the central axis Ax of the insertion hole 75. In other words, the inclination angle of the guide surface 92a with respect to the Z direction in which the insertion hole 75 extends is smaller than the inclination angle of the first inclined surface 71da with respect to the Z direction.

The second holding portion 62 and the diffusion member 21 hold each other. In the present embodiment, the protrusion 33c of the diffusion member 21 is fitted into the second engagement hole 95 of the second claw 90. As a result, the holder 24 is attached to the diffusion member 21 by the second claw 90. Further, the holder 24 is attached to the housing 11 via the diffusion member 21.

Specifically, the protrusion 33c of the diffusion member 21 contacts or approaches the second engaging portion 92 of the second claw 90. As a result, the protrusion 33c limits the holder 24 from moving (separating) from the diffusion member 21 in the + Z direction.

Further, the edge 33d of the protruding wall 33 of the diffusion member 21 and the tip of the intermediate wall 34 come into contact with or approach the second end surface 71b of the tubular portion 71. As a result, the edge 33d and the intermediate wall 34 limit the holder 24 from moving (approaching) in the −Z direction with respect to the diffusion member 21.

Further, the protrusion 33c is located between the two second pillars 91 of the second claw 90. As a result, the protrusion 33c restricts the holder 24 from moving in the Y direction with respect to the diffusion member 21.

FIG. 9 is a perspective view showing a part of the front cover 15 of the present embodiment. FIG. 10 is a perspective view showing another part of the front cover 15 of the present embodiment. As shown in FIGS. 9 and 10, the front cover 15 further has two protrusions 100.

Hereinafter, the two convex portions 100 may be individually referred to as convex portions 100A and 100B. The description common to the two convex portions 100A and 100B is described as an explanation about the convex portion 100. The convex portion 100A is an example of a fifth engaging portion. The convex portion 100B is an example of the sixth engaging portion.

Each of the two convex portions 100 projects in the substantially + Z direction from the inner surface 15b of the front cover 15. The convex portion 100A is located in the vicinity of one of the first side portions 21a. The convex portion 100B is located in the vicinity of the other first side portion 21a.

When the holder 24 is attached to the diffusion member 21 by the second claw 90, the convex portion 100 is fitted into the first engaging hole 85 of the holder 24. As a result, the convex portion 100 restricts the holder 24 from moving in the X direction with respect to the front cover 15.

The convex portion 100A can be engaged with the first engaging hole 85 of the first claw 80A. Further, the convex portion 100B can be fitted into the first engaging hole 85 of the first claw 80B, but cannot be engaged with the first engaging hole 85 of the first claw 80A. The convex portion 100A may be able to engage with the first engaging hole 85 of the first claw 80B.

For example, in the X direction, the width of the convex portion 100B is the same as or smaller than the width of the first engaging hole 85 of the first claw 80B, but the width of the first engaging hole 85 of the first claw 80A. Greater than. The convex portion 100 and the first engaging hole 85 are not limited to this example.

In the above PC 10, the light emitted from the light source 55 is incident on one end surface 22a of the light guide pipe 22. The light guide pipe 22 partially transmits the light to the other end surface 22a and partially emits the light from the outer peripheral surface 22b. Therefore, the light guide pipe 22 is made to emit light by the light source 55.

In this embodiment, one end face 22a of the light guide pipe 22 receives light from one light source 55, and the other end face 22a receives light from another one light source 55. Therefore, the light guide pipe 22 can shine substantially uniformly from one end face 22a to the other end face 22a.

The tubular portion 71 surrounds one light guide pipe 22 and one light source 55. Therefore, the tubular portion 71 allows the light emitted from one light source 55 to enter the one end surface 22a of the light guide pipe 22, but is emitted from another light source 55 adjacent to the light source 55. Prevents light from entering.

The light guide pipe 22 is accommodated in the accommodating groove 35 of the diffusion member 21. The light emitted from the outer peripheral surface 22b of the light guide pipe 22 is incident on the diffusion member 21. The diffusing member 21 diffuses the light emitted from the light guide pipe 22 and emits light by the light. As a result, the outer surface 31a of the diffusion member 21 exposed to the outside of the housing 11 emits light, and the appearance of the PC 10 is improved. The outer surface 31a is formed in a continuous seamless annular shape, and can shine substantially uniformly.

The curved portion 43 of the light guide pipe 22 is at least partially separated from the diffusion member 21. However, in the light guide pipe 22, the bent portion such as the curved portion 43 emits light more strongly than the substantially linear portion such as the first extending portion 41 and the second extending portion 42. Therefore, even if the light emitted from the curved portion 43 is attenuated in the space between the curved portion 43 and the diffusion member 21, the diffusion member 21 is substantially equivalent to the first extension portion 41 and the second extension portion 42. To emit light.

The PC 10 may emit light of different colors from two light sources 55 facing one light guide pipe 22. As a result, the color of the outer surface 31a of the diffusion member 21 can have a gradation. Further, the PC 10 may change the color of the light emitted from the light source 55 over time.

Hereinafter, as a part of the manufacturing method of the PC 10, a method of assembling the front cover 15, the diffusion member 21, the light guide pipe 22, the substrate 23, and the holder 24 will be illustrated. The method for manufacturing the PC 10 is not limited to the following method, and the front and back of the procedure may be interchanged, or another method may be used. First, two light guide pipes 22 are accommodated in the accommodating groove 35 of the diffusion member 21.

For example, the second extending portion 42 of the light guide pipe 22 projects in the + Z direction from the edge 33d of the protruding wall 33. The positions of the end faces 22a of the two light guide pipes 22 in the Z direction are adjusted to be approximately the same, but they do not have to be adjusted exactly the same. That is, the positions of the end faces 22a of the two light guide pipes 22 in the Z direction may be different from each other.

Next, the diffusion member 21 is fitted into the mounting groove 16 of the front cover 15. At this time, the protruding wall 33 and the intermediate wall 34 of the diffusion member 21 and the second extending portion 42 and the curved portion 43 of the light guide pipe 22 pass through the insertion hole 18.

Next, the substrate 23 is attached to the holder 24. For example, the substrate 23 is inserted between the two first claws 80 while elastically deforming the first claw 80. By inserting the convex portions 53b and 53c of the substrate 23 into the first engaging holes 85 of the first claws 80A and 80B, the substrate 23 is fixed to the holder 24, and the light source 55 mounted on the substrate 23 is the holder. It is housed in the insertion hole 75 of 24.

The convex portion 53b of the substrate 23 is inserted into the first engaging hole 85 of the first claw 80A, and the convex portion 53c is inserted into the first engaging hole 85 of the first claw 80B. When the substrate 23 is in a posture opposite to the desired posture, the convex portion 53c interferes with the first pillar portion 81 of the first claw 80A. As a result, the substrate 23 is attached to the holder 24 in a desired posture.

Next, the second extension 42 of the two light guide pipes 22 is inserted between the two second claws 90 of the holder 24. For example, the two light guide pipes 22 may face different directions from each other or may be separated from each other due to the elastic restoring force.

For example, the light guide pipe 22 is brought into contact with the guide surface 92a of the second claw 90. When the holder 24 moves so as to approach the diffusion member 21, the two inclined guide surfaces 92a bring the two light guide pipes 22 closer to each other, and the end faces 22a of the two light guide pipes 22 are inserted into the insertion holes 75 in the X direction. Get closer to. In this way, the guide surface 92a roughly bundles the two light guide pipes 22 and guides them to a desired position.

Next, the holder 24 is moved so as to be closer to the diffusion member 21, and the light guide pipe 22 is inserted into the insertion hole 75 of the holder 24. For example, the light guide pipe 22 is brought into contact with the first inclined surface 71da. When the holder 24 moves closer to the diffusion member 21, the inclined first inclined surface 71da and the second inclined surface 71db in order move the center of the end surface 22a of the light guide pipe 22 to the central axis Ax of the insertion hole 75. Get closer. In this way, the first inclined surface 71da and the second inclined surface 71db guide the light guide pipe 22 to a desired position.

While the holder 24 approaches the diffusion member 21, the protrusion 33c of the diffusion member 21 comes into contact with the guide surface 92a of the second claw 90. When the holder 24 approaches the diffusion member 21, the protrusion 33c elastically deforms the two second claws 90 so as to move away from each other, and gets over the second engaging portion 92 of the second claw 90. As a result, the protrusion 33c is inserted into the second engaging hole 95 of the second claw 90. As a result, the holder 24 is fixed to the diffusion member 21.

While the holder 24 approaches the diffusion member 21, the end surface 22a of the light guide pipe 22 comes into contact with the stopper 72 inside the insertion hole 75. When the holder 24 gets closer to the diffusion member 21, the stopper 72 pushes the end face 22a.

As shown in FIG. 4, the end 43b on the outer peripheral side of the curved portion 43 of the light guide pipe 22 is separated from the diffusion member 21. Therefore, the accommodating groove 35 of the diffusion member 21 has a spatial margin so that the curved portion 43 of the light guide pipe 22 pushed by the stopper 72 can approach the bottom surface 35a of the accommodating groove 35. The curved portion 43 of the light guide pipe 22 pushed by the stopper 72 approaches, for example, the bottom surface 35a inside the accommodating groove 35 and reduces the curvature.

Due to the movement and deformation of the curved portion 43, the holder 24 can be moved to a position where it can be attached to the diffusion member 21 without being hindered by the light guide pipe 22. Further, the restoring force of the curved portion 43 causes the light guide pipe 22 to press the end surface 22a against the stopper 72. As a result, the end surface 22a of the light guide pipe 22 comes into contact with the entire circumference of the stopper 72 substantially uniformly, and is maintained in a state orthogonal to the −Z direction in which light is emitted from the light source 55.

As described above, the positions of the end faces 22a of the two light guide pipes 22 in the Z direction may be different from each other before the holder 24 is attached to the diffusion member 21. In this case, the curved portions 43 of the two light guide pipes 22 bend inside the accommodating groove 35 with different curvatures. As a result, when the holder 24 is attached to the diffusion member 21, the positions of the end faces 22a of the two light guide pipes 22 in the Z direction are substantially the same.

When the holder 24 is attached to the diffusion member 21, the convex portion 100A of the front cover 15 is inserted into the first engaging hole 85 of the first claw 80A, and the convex portion 100B is the first engagement of the first claw 80B. It is inserted into the joint hole 85. When the holder 24 is in a posture opposite to the desired posture, the convex portion 100B interferes with the first pillar portion 81 of the first claw 80A. As a result, the holder 24 is attached to the diffusion member 21 and the front cover 15 in a desired posture.

Next, the board 23 is electrically connected to a circuit board such as a daughter board via a cable 57. As described above, the assembly of the front cover 15, the diffusion member 21, the light guide pipe 22, the substrate 23, and the holder 24 is completed.

As described above, the PC 10 (electronic device) has a substrate 23 on which the light source 55 is mounted and an end surface 22a (light receiving surface), respectively, and is flexible enough to transmit light incident on the end surface 22a from the light source 55. The substrate 23 is provided with a plurality of light guide pipes 22 (light guide pipes) and insertion holes 75 (holes) so that the end faces 22a of the plurality of light guide pipes 22 fitted in the insertion holes 75 and the light source 55 face each other. It includes a holder 24 for holding. With such a configuration, the positioning of the plurality of flexible light guide pipes 22 with respect to the light source 55 becomes easy, and the assembly of the PC 10 becomes easy.

Further, in the PC 10, the holder 24 has a stopper 72 that comes into contact with the end face 22a and restricts the end face 22a from approaching the light source 55. According to such a configuration, the distance between the light source 55 and the end face 22a can be maintained at a desired distance. Therefore, even if the lengths of the plurality of light guide pipes 22 are different from each other, the distance between the light source 55 and the end face 22a can be set to a desired distance, and the PC 10 can be easily assembled. Further, the light incident on the plurality of light guide pipes 22 becomes substantially uniform, and the appearance of the PC 10 is improved.

Further, the PC 10 is further provided with an accommodating groove 35 (groove) in which a plurality of light guide pipes 22 are accommodated, and further includes a diffusion member 21 for diffusing the light emitted from the plurality of light guide pipes 22, and a plurality of light guides. Each of the pipes 22 has a curved portion 43 bent in an arc shape inside the accommodating groove 35, and the end face 22a is pressed against the stopper 72 by the restoring force of the curved portion 43, so that the inner peripheral side and the outer peripheral side of the curved portion 43 are pressed. The ends 43a, 43b are at least partially separated from the diffusion member 21. According to such a configuration, the curved portion 43 can be bent with a curvature corresponding to the length of the light guide pipe 22. Therefore, even if the lengths of the plurality of light guide pipes 22 are different from each other, the distance between the light source 55 and the end face 22a can be set to a desired distance, and the PC 10 can be easily assembled. Further, the distance between the light source 55 and the end face 22a can be kept at a desired distance, and the orientation of the end face 22a can be kept at a desired direction.

Further, in the PC 10, the holder 24 is provided on the second claw 90 (wall) surrounding the plurality of light guide pipes 22 and the second claw 90 and is provided in the Z direction (first direction) orthogonal to the end surface 22a. It has a guide surface 92a that narrows as it approaches the light source 55, and is attached to the diffusion member 21 by the second claw 90. According to such a configuration, when the plurality of light guide pipes 22 are inserted into the insertion holes 75, the guide surface 92a can guide the plurality of light guide pipes 22 so as to approach the insertion holes 75. Further, by attaching the second claw 90 that guides the plurality of light guide pipes 22 by the guide surface 92a to the diffusion member 21, the holder 24 is attached to the light guide pipe 22. Therefore, the assembly of the PC 10 becomes easy. Further, since the second claw 90 also serves as a portion for guiding the plurality of light guide pipes 22 and a portion for attaching the holder 24 to the light guide pipe 22, the holder 24 can be miniaturized.

Further, in the PC 10, the holder 24 has a second inner peripheral surface 71d (inner surface) forming at least a part of the insertion hole 75, and the second inner peripheral surface 71d approaches the light source 55 in the Z direction. It narrows. According to such a configuration, the light guide pipe 22 inserted into the insertion hole 75 from a relatively wide inlet is guided to a desired position in the direction orthogonal to the Z direction as it approaches the light source 55 in the Z direction. .. Therefore, the end surface 22a of the light guide pipe 22 can be arranged at a desired position with respect to the light source 55. Further, since the inlet is relatively wide, it becomes easy to insert the light guide pipe 22 into the insertion hole 75.

Further, in the PC 10, the second inner peripheral surface 71d forms a first inclined surface 71da forming a part of the insertion hole 75 and another part of the insertion hole 75, and forms a first inclined surface 71da. It has a second inclined surface 71db that is aligned in the Z direction and is closer to the light source 55 than the first inclined surface 71da, and the inclination angle of the first inclined surface 71da with respect to the central axis Ax of the insertion hole 75 is inserted. It is larger than the inclination angle of the second inclined surface 71db with respect to the central axis Ax of the hole 75. According to such a configuration, the inlet of the insertion hole 75 can be set wide, and the light guide pipe 22 can be smoothly guided to a desired position in the direction orthogonal to the Z direction.

Further, in the PC 10, the width of the guide surface 92a is larger than the width of the second inner peripheral surface 71d in the X direction (second direction) orthogonal to the Z direction. According to such a configuration, the plurality of light guide pipes 22 are guided so as to approach the insertion hole 75 by the wider guide surface 92a in the direction orthogonal to the Z direction. After that, the light guide pipe 22 inserted into the insertion hole 75 is guided to a desired position with respect to the light source 55 by the second inner peripheral surface 71d. Therefore, the guide surface 92a can smoothly guide the plurality of light guide pipes 22 to a desired position with respect to the light source 55.

Further, in the PC 10, the inclination angle of the guide surface 92a with respect to the central axis Ax of the insertion hole 75 is smaller than the inclination angle of the first inclined surface 71da with respect to the central axis Ax of the insertion hole 75. According to such a configuration, the inclination angle of the guide surface 92a with respect to the central axis Ax of the insertion hole 75 is set to be small, and the length of the guide surface 92a in the Z direction is set to be long. As a result, the guide surface 92a can guide the plurality of light guide pipes 22 so as to smoothly approach the insertion holes 75.

Further, in the PC 10, the holder 24 has a first engaging hole 85 (first engaging portion) of the first claw 80A and a first engaging hole 85 (second engagement portion) of the first claw 80B. The substrate 23 has a convex portion 53b (third engaging portion) capable of engaging with the first engaging hole 85 of the first claw 80A, and a first claw 80B. It has a convex portion 53c (fourth engaging portion) that can be engaged with the first engaging hole 85 and is not engaged with the first engaging hole 85 of the first claw 80A. According to such a configuration, when the substrate 23 is attached to the holder 24, it is possible to prevent the convex portion 53c from being erroneously engaged with the first engaging hole 85 of the first claw 80A. Therefore, the substrate 23 is attached to the holder 24 in a desired posture, and the light source 55 and the end surface 22a of the desired light guide pipe 22 can face each other.

Further, the PC 10 further includes a substrate 23, a plurality of light guide pipes 22, and a housing 11 for accommodating the holder 24, and the housing 11 engages with the first engaging hole 85 of the first claw 80A. It is possible to engage with the possible convex portion 100A (fifth engaging portion) and the first engaging hole 85 of the first claw 80B, and is engaged with the first engaging hole 85 of the first claw 80A. It has a convex portion 100B (sixth engaging portion) that cannot be fitted. According to such a configuration, when the holder 24 is attached to the housing 11, it is possible to prevent the convex portion 100B from being erroneously engaged with the first engaging hole 85 of the first claw 80A. Therefore, the holder 24 can be attached to the housing 11 in a desired posture, and the light guide pipe 22 that receives light from the light source 55 that emits desired light can be arranged at a desired position of the housing 11. Become.

The holder 24 has an insertion portion 60 provided with insertion holes 75 (holes) into which a plurality of flexible light guide pipes 22 (light guide pipes) are inserted, and end faces of the light source 55 and the plurality of light guide pipes 22. It has a first holding portion 61 (holding portion) that holds the substrate 23 on which the light source 55 is mounted so as to face the 22a (light receiving surface). With such a configuration, the positioning of the plurality of flexible light guide pipes 22 with respect to the light source 55 becomes easy.

In the embodiment described above, one light source 55 and one end face 22a of the light guide pipe 22 face each other. However, for example, one light source 55 and the end faces 22a of the plurality of light guide pipes 22 may face each other.

Further, the holder 24 has a first claw 80 and a second claw 90 that are attached to the diffusion member 21 and the substrate 23 with elastic deformation. However, the diffusion member 21 and the substrate 23 may have a portion that is attached to the holder 24 with elastic deformation.

Further, the convex portions 53b and 53c of the substrate 23 and the convex portions 100A and 100B of the housing 11 are inserted into the first engaging hole 85 of the first claw 80. However, the holder 24 may be provided with a convex portion, and the substrate 23 and the housing 11 may be provided with a hole or a notch into which the convex portion is inserted.
