In the modernization of a hall display device, the number of cables connected to operating equipment may increase since the shape and the number of pushbuttons, indicators and the like are changed. In this case, it is necessary to further process a hole at the worksite for passing the cables in accordance with the number of cables, which makes the work complicated. In the present invention, a frame having an opening in the center is fixed to a hall wall, and a front plate having operating equipment is fixed in a way as to cover the opening on the hall side of the frame. A back plate having a hole for passing cables is detachably fixed in a way as to cover the opening on the elevator hoistway side.
