  As shown in FIG. 2, the main body 11 has a first main body 15 that forms the back side (first direction side) of the main body 11 and a second main body that forms the front side (second direction side) of the main body 11. And two main body portions 16. A first light emitting member 20A and a second light emitting member 20B are arranged between the first main body 15 and the second main body 16. The first light emitting member 20A and the second light emitting member 20B are superimposed, and are sandwiched between the first main body 15 and the second main body 16 in the superposing direction.

  A light source unit cover 17 is attached to an outer surface of the first main body 15. The light source unit cover 17 holds a light source 18 such as an LED, a control circuit (not shown) for controlling turning on and off of the light source 18, a battery (not shown), and the like. A hole 19 is provided in the first main body 15 at a position where the light source cover 17 is attached. When the light source cover 17 is attached to the first main body 15, the light source 18 held by the light source cover 17 is provided. Is inserted into the main body 11 through the hole 19.

  The light source 18 housed inside the main body 11 is disposed to face the first light emitting member 20A among the first light emitting member 20A and the second light emitting member 20B that are superimposed. The light from the light source 18 is incident on the first light emitting member 20A, and is incident on the second light emitting member 20B via the first light emitting member 20A. The first light emitting member 20A and the second light emitting member 20B are made of a transparent or translucent resin material such as acrylic or polycarbonate.

The light that has entered the first light emitting member 20A is guided inside the first light emitting member 20A, reaches the first light emitting units 21A to 25A, and is emitted from the first light emitting units 21A to 25A. In a state where the five openings 14 of the first main body 15 are exposed, the light emission of the first light emitting units 21A to 25A can be visually recognized through these openings 14.

  The second light-emitting member 20B has five second light-emitting parts 21B to 25B that are arranged so as to overlap with the five openings 14 of the second main body 16, respectively. The light that has entered the second light emitting member 20B is guided inside the second light emitting member 20B, reaches the second light emitting units 21B to 25B, and is emitted from the second light emitting units 21B to 25B. In a state where the five openings 14 of the second main body 16 are exposed, the light emission of the second light emitting units 21B to 25B can be visually recognized through these openings 14.

  3 and 4 show the first light emitting member 20A.

  The first light emitting member 20A has a first light splitting unit 26A and five first light guides 27A to 31A. The light from the light source 18 first enters the first beam splitting unit 26A, and the light incident on the first beam splitting unit 26A is split into a plurality of directions by the first beam splitting unit 26A. The first light guides 27A to 31A extend radially from the first beam splitter 26A, and guide the light split by the first beam splitter 26A in the length direction of each light guide.

  The five first light emitting portions 21A to 25A are provided at the distal ends of the first light guides 27A to 31A. The front sides of the first light emitting units 21A to 25A shown in FIG. 3 are formed in a flat plate shape, and the front sides of the first light emitting units 21A to 25A face the five openings 14 of the first main body unit 15. The first light emitting member 20A is assembled to the first main body 15. On the other hand, the rear side of the first light emitting portions 21A to 25A shown in FIG. The light guided to the first light emitting units 21A to 25A is scattered by irregularities on the rear surface side of each light emitting unit, and is emitted from the front surface side of each light emitting unit.

  Of the first light guides 27A to 31A, the first light guide 27A is formed to be the longest. The first light-emitting member 20A is formed symmetrically about an axis X extending through the first beam splitter 26A and along the first light guide 27A, and the first light-guiding member 20A excluding the first light guide 27A. Among the light bodies 28A to 31A, the first light guide 28A and the first light guide 29A are symmetrical, and the first light guide 30A and the first light guide 31A are symmetrical. The first light guides 28A and 29A are formed to be the shortest, and the first light guides 30A and 31A are formed shorter than the first light guide 27A and longer than the first light guides 28A and 29A. Have been.

  The front side of the first light guides 27A to 31A shown in FIG. 3 is formed in a flat plate shape. On the other hand, a rib 32 is provided on the rear surface side of the first light guides 27A to 31A shown in FIG. The ribs 32 of each of the first light guides 27A to 31A extend in the longitudinal direction of each light guide, and are formed integrally with each light guide.

  By forming the ribs 32 using the first light guide 27A as an example, the thickness of the first light guide 27A at the location where the rib 32 is formed increases. Thereby, when light is guided inside the first light guide 27A toward the tip end portion (first light emitting portion 21A) of the first light guide 27A, the light is repeated inside the first light guide 27A. Light reflection is reduced, and light guiding efficiency is increased. From the viewpoint of increasing the light guide efficiency, the rib 32 formed on the first light guide 27A preferably extends from the first beam splitter 26A to the tip of the first light guide 27A (first light emitting unit 21A).

  Since the thickness of the first light guide 27A is partially increased at the location where the rib 32 is formed, the thickness of the first light guide 27A during molding is smaller than when the entire first light guide 27A is formed thick. Deformation of the first light guide 27A due to contraction is suppressed. By suppressing the deformation of the first light guide 27A, for example, the assembly of the first light emitting member 20A and the first main body 15 and the assembly of the first light emitting member 20A and the second light emitting member 20B become easy. The same applies to the other first light guides 28A to 31A. The formation of the ribs 32 increases the light guide efficiency and the moldability.

  The ribs 32 of each of the first light guides 27A to 31A are not limited to one for each light guide, and a plurality of ribs 32 may be provided. When a plurality of ribs 32 can be provided for each light guide, the number of ribs 32 may be set according to the length of each of the first light guides 27A to 31A, and preferably, a relatively long light guide is used. The number of ribs 32 is set to be larger for the body. In the example shown in FIG. 4, the longest first light guide 27A among the first light guides 27A to 31A is provided with seven ribs 32, and the shortest first light guides 28A and 29A are provided. Two ribs 32 are provided, and three ribs 32 are provided on the first light guides 30A and 31A having an intermediate length.

  The light guide efficiency of each of the first light guides 27A to 31A is also related to the length of each light guide. The longer the light guide, the lower the light guide efficiency. The setting can compensate for a decrease in light guide efficiency due to the length. Thereby, the light guide efficiency of each of the first light guides 27A to 31A can be adjusted, and the luminance of the first light emitting units 21A to 25A can be made uniform.

  With reference to FIG. 2, the second light emitting member 20B has a second light splitting unit 26B and five second light guides 27B to 31B, and the five second light emitting units 21B to 25B are connected to the second light guide 21B to 25B. It is provided at the tip of the light bodies 27B to 31B. The second beam splitting unit 26B is formed in the same manner as the first beam splitting unit 26A of the first light emitting member 20A, and the five second light guides 27B to 31B are the five first light guides of the first light emitting member 20A. It is formed identically to the bodies 27A to 31A, and the five second light emitting units 21B to 25B are formed identically to the five first light emitting units 21A to 25A of the first light emitting member 20A. That is, the first light emitting member 20A and the second light emitting member 20B are the same member.

  Then, the first light-emitting member 20A and the second light-emitting member 20B are overlapped with their rear surfaces facing each other. As described above, the first light emitting member 20A has a symmetrical shape about the axis X, and the second light emitting member 20B also has a symmetrical shape. Therefore, five first light guides 27A to 31A and five second light guides 27B to 31B are paired with the first light guide and the second light guide that are arranged to face each other in the overlapping direction. Are five pairs (a first light guide 27A and a second light guide 27B, a first light guide 28A and a second light guide 29B, a first light guide 29A and a second light guide). (A pair of the body 28B, a pair of the first light guide 30A and the second light guide 31B, and a pair of the first light guide 31A and the second light guide 30B).

  FIG. 5 schematically shows light paths in the first beam splitting unit 26A and the second beam splitting unit 26B.

  The light source 18, the first beam splitting unit 26A, and the second beam splitting unit 26B are arranged in this order in the overlapping direction of the first light emitting member 20A and the second light emitting member 20B. A conical first prism surface 33A that is concave with respect to the light source 18 is provided on the front side of the first beam splitting unit 26A. A conical second prism surface 33B formed in the same shape as the first prism surface 33A is also provided on the front side of the second beam splitting unit 26B, but the second prism surface 33B is formed of the first prism surface 33A. On the contrary, it becomes convex with respect to the light source 18.

  The light from the light source 18 passes through the first prism surface 33A and enters the first beam splitter 26A. Part of the light incident on the first beam splitting unit 26A is reflected toward the first beam splitting unit 26A at the boundary B1 between the first beam splitting unit 26A and the second beam splitting unit 26B, and part of the light is emitted. Passes through the boundary portion B1 and enters the second beam splitting portion 26B. The light reflected on the first beam splitting unit 26A side is reflected in all directions by 360 ° by the first prism surface 33A, and is divided into a plurality of lights incident on the first light guides 27A to 31A. On the other hand, the light incident on the second beam splitter 26B is reflected in all directions by 360 ° by the second prism surface 33B, and is split into a plurality of lights incident on the second light guides 27B to 31B.

  Here, if the apex angle θ of the first prism surface 33A and the second prism surface 33B is excessively small, the incident angle at which the light from the light source 18 enters the first prism surface 33A becomes excessively large, and the first prism Light passing through the surface 33A and entering the first beam splitter 26A decreases. If the apex angle θ is excessively large, the incident angle when entering the second prism surface 33B becomes excessively small, and light passes through the second prism surface and escapes outside the second beam splitting unit 26B. . Assuming that the critical angle at which total reflection occurs at the first prism surface 33A and the second prism surface 33B is α, the apex angle θ is preferably such that the incident angle of light on the first prism surface 33A is the critical angle over the entire first prism surface. α, the incident angle of light with respect to the second prism surface 33B is set to be equal to or greater than the critical angle α over the entire second prism surface, and the refractive index of the material of the first light emitting member 20A and the second light emitting member 20B is also set. Although it depends, for example, it is 110 ° to 130 °.

  FIG. 6 schematically shows light paths in the first light guide 27A and the second light guide 27B.

  As described above, part of the light reflected by the first prism surface 33A is incident on the first light guide 27A, and part of the light reflected by the second prism surface 33B is The light enters the second light guide 27B. The light incident on the first light guide 27A is guided toward the tip end (first light emitting portion 21A) of the first light guide 27A, and the light incident on the second light guide 27B is The light is guided toward the distal end portion (second light emitting portion 21B) of the second light guide 27B.

  Here, the ribs 32 of the first light guide 27A and the ribs 32 of the second light guide 27B are formed by the first light emitting member 20A and the second light emitting member 20B being superposed on each other with their rear surfaces facing each other. , In the overlapping direction. As described above, since the first light guide 27A and the second light guide 27B are suppressed from being deformed due to shrinkage during molding, the ribs 32 come into close contact with each other. The light incident on the first light guide 27A and the light incident on the second light guide 27B cross the first light guide 27A and the second light guide 27B across the boundary B2 between the ribs 32. , And are mixed together toward the respective distal ends of the first light guide 27A and the second light guide 27B. For this reason, even if the amount of incident light is different between the first light guide 27A and the second light guide 27B that form a pair, the luminance of the first light emitting portion 21A and the luminance of the second light emitting portion 21B are made uniform.
