問題となつていた。<Prior art and problems> In the conventional backboard mounting structure, a mounting hole is provided along the periphery of the backboard, and a backboard supporting bracket is attached to the front surface of the backboard (printed board connection surface) via an insulating plate through this mounting hole. The back board was attached to the rack frame by screwing the bracket to the rack frame and fixing the bracket to the rack frame. Furthermore, power was supplied to the backboard through power connection ears provided on both sides of the backboard. In such a backboard mounting structure, since a mounting hole for screw connection with the bracket is formed in the backboard, a wiring pattern cannot be formed in this mounting hole portion.
It became a prohibited area for wiring, making it impossible to improve the printed wiring density of the backboard. Furthermore, since power is supplied from the end of the backboard, voltage drop at the center of the backboard has been a problem, especially when the power supply current is large.
