The opaque synthetic resin is formed as a support layer by the two-color molding. "

The above solution works as follows. In this case, since the periphery of the see-through window has a composite color of the opaque constituent wall and the light-transmitting synthetic resin layer, the color of the box is mainly made of the opaque synthetic resin, and a color different from the color of the see-through window. It becomes the border of. Therefore, a border portion of a different color is formed between the range in which various displays can be seen through and the box-based color portion. Further, since the see-through window is made of a light-transmitting resin exhibiting a smoke color, the unsightly portion other than the light-emitting portion (display portion) is concealed by the smoke color.

Further, when the portion of the see-through window is "red smoke color" as in the invention of claim 2, the normal color (green other than red and yellow) displayed by the fluorescent display tube is whitened. You can see through. According to a third aspect of the present invention, in the first aspect, the box main body is composed of a flat front half opened to the back side and a flat bottom half opened to the front side. And a hollow body joined at the open ends of these halves, and the see-through window is formed in the front plane portion of the front half. "
