<p>PURPOSE:To simplify the assembly work by forming a protective structure by a guide without fixing an extension substrate with a screw. CONSTITUTION:When an extension substrate 1 is inserted vertically into an intermediate base from the upper part by using a slit 12 as a guide, the extension substrate 1 stops in a position in which it hits against a main frame 4 by its dead weight, and becomes movable in two directions within a restriction range of the guide. Subsequently, when a main substrate 2 is inserted into the main frame 4 along a guide part by a slide in the horizontal direction, a connection of connectors of the main substrate 2 and the extension substrate 1 can be executed smoothly by a movement in two directions of the extension substrate 1. In such a way, since there is the degree of freedom for attaching the extension substrate 1, it can be attached without making the fitting dimension accuracy strict, and the assembly workability is improved.</p> |
