PROBLEM TO BE SOLVED: To solve the problem in inspecting the back side of a unit stored in a control board that drawing the unit up to a position where inspection can be carried out may cause to make the unit come off from a guide rail on the way of reaching this position, and it is difficult to inspect the depth other than the front in a state that the wiring is connected and drawing the unit is also difficult. SOLUTION: Fixed rails for supporting the unit are provided on both side faces of the control board. Extension rails having slots on the rail sides are provided parallel to the fixed rails. Locking bars provided on the side faces of the unit are put through the slots of the extension rails. By this constitution, the unit slides on the fixed rails and the extension rails follow the unit when the locking bars contact with the slots.
