The upper horizontal sheet 91 and the heat transfer sheet 33 are accommodated in the light source box 412 . The heat transfer sheet 33 and the heat transfer sheet 34 described later are formed of polysiloxane, and the material is not particularly limited.

The box cover 35 for closing the upper opening of the light source box 412 is detachably mounted on the light source box 412 . The box cover 35 is formed of resin. As the resin forming the case cover 35, for example, ABS resin is suitably used, but is not particularly limited to ABS resin. In addition, the material of the box cover 35 may be metal instead of resin, and is not particularly limited.

As shown in FIG. 4 , the lower vertical piece 94 is arranged in the gap 31 . The front surface of the lower vertical sheet 94 contacts the rear surface of the base portion 61 of the holding case 6 via the heat transfer sheet 34 . As shown in FIG. 2 , a through hole 941 through which a fixing tool (not shown) such as a small screw is passed is formed in the lower vertical piece 94, and the fixing tool is screwed into the base portion formed in the holding box 6 through the through hole 941. The heat conduction member 9 is mounted on the holding box 6 through the screw hole (not shown) of 61 . In the present embodiment, by forming two through holes 941 in the lower vertical piece 94 by extending a distance in the up-down direction, the rotation of the heat-conducting member 9 with respect to the holding case 6 can be suppressed.

With the heat conduction member 9 , the heat generated in the light source 41 depends on the heat transfer sheet 33 , the upper horizontal sheet 91 , the upper vertical sheet 92 , the lower horizontal sheet 93 , the lower vertical sheet 94 , the heat transfer sheet 34 , and the base of the holding box 6 . Sequential conduction of 61. Since the thermally conductive member 9 and the holding case 6 have high thermal conductivity, the heat generated in the light source 41 can be dissipated efficiently.

The heat conduction member 9 is combined with the lighting unit 4 (the light source 41 and the light guide member 42 ) and the holding box 6 to constitute a lighting unit. The lighting unit is held on the installation base 7 .

(2.3.7) End caps

The lighting unit 3 further has an end cover 36 . The end cap 36 is arranged on the lower end of the light guide member 42 and the holding box 6 . The end cover 36 is installed on the installation base 7 and can also be installed on other components. The end cap 36 is formed of resin. The resin that forms the end cap 36 is suitably used, for example, AS (Acrylonitrile Styrene: acrylonitrile/styrene) resin, not particularly limited to AS resin, and may not be resin, and the material is not particularly limited. In addition, the end cap 36 may also have high light transmittance. In particular, when the lower end face of the light guide member 42 has the function of a light emitting portion, the end cap 36 should preferably have high transmittance (preferably, the transmittance in the visible light region is 100%). In addition, when the lower end surface of the light guide member 42 is not to function as a light emitting portion, the end cap 36 should preferably have low transmittance (preferably, the transmittance in the visible light region is 0%).

(2.4) The position of the boundary of the lighting cover

The position in the front-rear direction of the boundary 56 of the first portion 54 located on the front side and having the first transmittance and the second portion 55 located on the rear side and having the second transmittance lower than the first transmittance is in the cabinet In front of the position of the front end of the main body 1 . The front end portion of the cabinet body 1 refers to a portion of the front end portion other than the recess 16 of the partition wall 15 .

As described above, the light transmittance of the front surface portion 51 of the lighting cover 5 is higher than the light transmittance of the rear end portion of the side surface portion 52 . That is, since the front surface portion 422 of the light guide member 42 is the light exit portion 40, the light transmittance of the front surface portion 51 of the lighting cover 5 is formed to be high. On the other hand, since the side surface portion 423 of the light guide member 42 is not the light emitting portion 40, it is not necessary to make the light transmittance of the side surface portion 52 of the lighting cover 5 high, but to make the light transmittance of the side surface portion 52 of the lighting cover 5 low. , and it is better to increase the reflection (including diffuse reflection) of the inner surface of the side surface portion 52 . As a result, the light emitted from the side surface portion 423 of the light guide member 42 is reflected on the inner surface of the side surface portion 52 of the lighting cover 5 , and returns to the light guide member 42 or travels forward. Quantity is easy to increase.

In addition, when the position of the boundary 56 of the first part 54 and the second part 55 of the lighting cover 5 in the front-rear direction is behind the position of the front end of the cabinet body 1, the light is emitted from the side surface 423 of the light guide member 42, The light transmitted through the first portion 54 of the lighting cover 5 reaches the cabinet body 1 and does not travel forward, and the amount of light traveling forward from the lighting portion 4 tends to decrease.

In addition, if the light transmittance of the material forming the first portion 54 is higher than that of the material forming the second portion 55, the light transmittance is reduced compared to forming a surface embossing or the like on the surface of the second portion 55. It is easier to adjust the transmittance. In particular, the light transmittance in the visible light region, which is the light transmittance of the material forming the first portion 54, is 50% or more and 100% or less. The light transmittance in the visible light region, which is the light transmittance of the material forming the second portion 55, is 0% or more and 30% or less, whereby the transmission of the light of the first portion 54 and the transmission of the light of the second portion 55 can be easily ensured. reflection.

In addition, by forming the push-pull portions 53 on the side portions 52 on both sides of the lighting cover 5, the front width can be narrowed, and the amount of light traveling forward can be easily increased.

In addition, by forming the push-out portion 424 at the front end portion of the side surface portion 423 of the light guide member 42, the amount of light emitted downward from the lower end surface of the light guide member 42 tends to increase.

In addition, the position of the light emitting portion 40 of the light guide member 42 in the front-rear direction is in front of the position of the front end of the cabinet body 1 , and the position of the rear end of the light guide member 42 in the front-rear direction is in the front end of the cabinet body 1 . behind the position of the department.
