PURPOSE: To comply with a change in the panel height of a casing and reduce a cost by combining a plurality of decorative panels with the same width as that of the casing and different heights.

CONSTITUTION: Decorative panels 10 and 11 which are part of electronic equipment casings 6 are constructed such that a plurality of increased panels 1 and fundamental panels 2 and 3 with different heights are combined to form the electronic equipment casings 6 with a variety of panel heights(h). The height(h) of the electronic equipment casing 6 with the same front width changes from minimum 50mm to maximum 500mm at a unit of 50mm. For example, the projection 2a of the fundamental panel 2 engages the U-shaped groove 1b of an intermediate increased panel 1 and the projection 1a of the increased panel 1 and the U-shaped groove 1b of an upper increased panel 1 are combined in engagement to form the decorative panel 10. In this case, when the heights (h1) and (h3) of the fundamental panel 2 and the increased panel 1 are 50mm and 100mm, respectively, the combination of the one fundamental panel 2 and the two increased panels 1 can comply with the electronic equipment casing 6 with the height(h) of 250mm.
