DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to the structure of a 'y% transmitter storage rack on which all printed board storage blocks are mounted.

(2) Background of the technology This type of communication device storage rack has multiple printed board storage blocks in multiple vertical rows (often two or three rows).
There are cable ducts that are arranged and mounted [-7, adjacent to the side surfaces of the block group and penetrate vertically, and the external shape is formed into a phase shape. Here, the printed board storage block refers to a casing that stores a plurality of glint wiring boards on which electronic components are mounted and has a predetermined electrical function. Further, the external dimensions (width, depth, and height dimensions) of this type of communication device storage rack are often standardized. Therefore, in order to meet this standard dimension, printed board storage blocks (hereinafter referred to as blocks) are mounted on storage racks so that the outer surfaces of each block, that is, the front and side surfaces, are located in one plane. need to be aligned. The cable duct is provided when there are many wiring cables from outside the storage rack for each block, and is used as a wiring area for these cables. However, for each storage rack, the amount of wiring cables may be very large or may be relatively small. Furthermore, the width dimension (left and right dimension) of the block to be mounted may be large or small. Therefore, there is a need for a communication device housing frame structure that allows the width dimensions (left and right dimensions) of the cable duct and the dimensions of the block mounting width to be easily set to desired values.

(3) Prior Art and Problems FIG. 1 is a horizontal cross-sectional view of a conventional communication device housing rack structure. In the same figure, when facing the drawing, the left hand side is the left side of the storage rack, the right hand side is the right side, the lower side is the front side, and
