PROBLEM TO BE SOLVED: To prevent improper operation of switch.SOLUTION: Even when a device body A placed on a floor is stepped on by a foot (shoe), an operation part 60 is guarded by a top plate 20 of a cover 2 from being subjected to a pressing force from the sole of the foot (shoe sole). That is, since the operation part 60 of a switch 6 is exposed out of the device body A from bottom face of the concave portion 27, compared to a conventional case where the operation part of a switch is exposed out of the device body from the surface of the top plate 20 of the cover 2, the provability that the switch is accidentally operated is largely reduced. |
