It is structured into a mold. In order to effectively use light, the upper surface of the bottom plate 11 is preferably white. Similarly, it is preferable that the inner surface of the side plate 12 and the lower surface of the upper frame plate 13 are also white.

  In the present embodiment, the upper lid 3 is composed of a plate-like scattering and transmitting member that scatters while transmitting light, and is specifically composed of a milky white translucent plate made of resin or the like. A region R corresponding to the opening 13 a of the upper frame plate 13 in the upper lid 3 is an observation surface observed from above as a light emitting region that emits light based on light from the white fluorescent lamp 4. Therefore, in the present embodiment, the upper lid 3 serves as an observation surface forming unit that forms an observation surface. In the present invention, the observation surface forming unit may be configured by using, for example, a sheet-like scattering transmission member that diffuses light while transmitting light, specifically, a cloth or the like. In the present invention, the observation surface forming portion may be configured using, for example, a mesh-like or porous sheet-like or plate-like member, specifically a punching metal plate.

  The four linear white fluorescent lamps 4 are arranged along the four side plates 12 in the main body 2. In the drawing, the illustration of the socket and wiring of the fluorescent lamp 4 is omitted. The upper frame plate 13 is positioned above the four linear white fluorescent lamps 4 so that the white fluorescent lamp 4 cannot be seen from above.
