Here, with reference to FIGS. 1 to 4, a procedure for accommodating the shelf plate 31 in the cabinet body 2 will be described.
The worker attaches the shelf support parts 32, 32,... And the first metal fittings 51, 51 of the light source holding parts 5, 5 to the cabinet body 2.
Next, the worker pulls the connector 331 into the inside of the cabinet body 2 from the rear side of the back plate 22 through the power feeding insertion holes 221, 514 and connects it to the light source board 42. Next, the worker arranges the connector 331 inside the power supply insertion holes 221 and 514. As a result, the connector 331 partially closes the power feed insertion holes 221 and 514.
The power supply line 332 connected to the connector 331 is drawn out to the rear side of the back plate 22. The worker connects the power supply line 332 to the power supply box 34 on the rear side of the back plate 22.

Next, the worker attaches the left and right sides of the shelf plate 31 to the shelf support parts 32, 32,.... In the present embodiment, the shelf board 31 is inserted inside the U-shape of the shelf board support portion 32.
Next, the operator places the rear end portion of the lower surface of the shelf plate 31 on the first cushioning member 53 from above. As a result, the lower surface of the shelf board 31 is mounted on the upper surface of the mounting board 512 via the first cushioning member 53. Further, the light incident surface 31a of the shelf plate 31 is arranged to face the light sources 41, 41,.... In other words, the light incident surface 31a is an end surface of the shelf plate 31 facing the back plate 22 side, and the holding plate 511 holds the light sources 41, 41,... toward the light incident surface 31a.

Next, the operator places the cover plate 522 from the upper side on the rear end portion on the upper surface of the shelf plate 31 via the second cushioning member 54, and mounts the mounting plate 521 on the upper surface of the receiving plate 513 from the upper side. Place it. Further, the worker screws the second fitting 52 to the first fitting 51.
As a result, the covering plate 522 covers the upper surface of the shelf plate 31 via the second cushioning member 54.

The shelf plate 31 is sandwiched between the mounting plate 512 of the first metal fitting 51 and the covering plate 522 of the second metal fitting 52 via the first buffer member 53 and the second buffer member 54.
The second metal fitting 52 is detachably attached to the first metal fitting 51. Therefore, it is not necessary to slide the lower surface and the upper surface of the shelf plate 31 on the mounting plate 512 and the covering plate 522, both when the shelf plate 31 is attached to the light source holding unit 5 and when the shelf plate 31 is removed from the light source holding unit 5. .. Therefore, it is possible to suppress damage to the shelf plate 31 when the shelf plate 31 is attached and detached.

The light sources 41, 41,... illuminate the shelf plate 31 with light. The light emitted from each light source 41 enters the inside of the shelf plate 31 from the light incident surface 31a. The light incident on the inside of the shelf plate 31 is transmitted through the inside of the shelf plate 31, is repeatedly reflected on both upper and lower surfaces of the shelf plate 31, and is emitted from the light emitting surface 31b to the outside of the shelf plate 31. As a result, the shelf board 31 shines.
The light incident on the inside of the shelf board 31 is partially reflected by the upper surface or the lower surface of the shelf board 31. Therefore, the upper surface or the lower surface of the shelf board 31 also functions to some extent as the light emitting surface 31b.
Note that, for example, the upper surface or the lower surface of the shelf board 31 may be covered with a light reflection sheet so that the light incident on the upper surface or the lower surface of the shelf board 31 is totally reflected.

Since the light source holder 5 has a non-translucent property, it is possible to suppress light leakage due to the light emitted by the light source 41 passing through the light source holder 5. Further, since the light source holding unit 5 does not reflect light, it is possible to suppress light leakage due to the light emitted from the light source 41 being reflected by the light source holding unit 5. Since the power supply insertion holes 221 and 514 are partially closed by the connector 331, the amount of light leaking to the rear side of the back plate 22 through the power supply insertion holes 221 and 514 can be reduced.
Each light source 41 generates heat as it emits light. However, since the light source holder 5 is made of metal, it has high heat dissipation. The heat generated by the light source 41 is transferred to the light source holding unit 5 via the light source substrate 42 and is radiated to the outside from the light source holding unit 5.

Two power supply insertion holes 221 of the back plate 22 may be provided for each light source holding unit 5. In this case, the two power feed insertion holes 221 and 221 are juxtaposed in the left-right direction. The worker associates the power feed insertion hole 221 closer to the arrangement position of the power source box 34 with the power feed insertion hole 514 of the light source holding unit 5, and holds the power feed insertion hole 221 farther from the arrangement position of the power source box 34 as the light source. It is closed by the holding plate 511 of the part 5.
In the light source holder 5, the inner surfaces of the first metal fitting 51 and the second metal fitting 52 have non-light-reflecting properties (for example, the metal surface is colored black), and the first metal fitting 51 and the second metal fitting 52 are provided. Each outer surface may be light-reflecting (for example, may be a metal surface as it is).

Next, with reference to FIGS. 1 and 2, a mechanism for switching lighting/non-lighting of the light sources 41, 41,... With opening/closing of the doors 25, 25 will be described.

The other end surface of the open/close detection unit 61 is a detection surface.

The open/close detection units 61, 61 are held by the detection holding unit 7.
The detection holder 7 has a rectangular plate shape and is arranged in parallel to the bottom plate 23.
On one end surface (first surface) of the detection holding section 7, two housing holes 71, 71 are arranged in parallel in the longitudinal direction of the one end surface of the detection holding section 7. The housing holes 71, 71 are arranged at the central portion in the longitudinal direction of the one end face of the detection holding unit 7. The opening/closing detectors 61, 61 are housed in the housing holes 71, 71 one by one.
Two insertion ports 72, 72 are provided on one surface (second surface) of the detection holding unit 7. The one insertion port 72 communicates with the bottom portion of the one accommodation hole 71. Similarly, the other insertion port 72 communicates with the bottom portion of the other accommodation hole 71. The connection wire 62 is inserted through each insertion port 72.

The operator directs the end surface of the detection holding unit 7 where the accommodation hole 71 is provided to the front side, and the surface of the detection holding unit 7 where the insertion port 72 is provided to the upper side.
