PROBLEM TO BE SOLVED: To provide electronic equipment in which a direction of installation can be freely selected and which is not affected by the size of an installation place and has no danger of short-circuiting an electronic circuit inside a case due to installation screws. SOLUTION: The electronic equipment is installed on a wall by hooking a plurality of installation holes continuously comprising a through hole with a diameter larger than that of the head of a screw, and elongated holes allowing the shaft of the screw to insert and not allowing the head to insert on the screw previously screwed on the wall. In the equipment, a wall for restricting the insertion of the screw is provided inside the case, the elongated holes are provided on the insertion hole of at least one of the installation hole. The axial lines of the insertion hole and the respective elongated holes of the installation hole are each almost integer multiple of a right angle.
