Abstract
Abstract A casing construction including a left post and a right post, each of the left post and the right post being large in width and formed at its front surface with a mounting portion for mounting a plurality of shelves in a plurality of vertically arranged layers, at its rear surface with a mounting portion for mounting a back board, a mounting portion at its upper end for mounting a ceiling board and a mounting portion at its lower end for mounting a floor board. The left post and right post having a variety of functions to perform have the shelves, back board, ceiling board and floor board threadably connected thereto. In this casing construction, the left post and right post perform the function of separating the shelves from cables. A plurality of such casings can be arranged in side-by-side relation to provide a series of casings depending on the size of the electronic equipment intended.
