A sliding member provided on a front panel of a case so as to be vertically moveable, the sliding member being positioned in a lower position under its own weight, is provided with a window portion that covers a screw insertion hole for fixing a unit in place when the sliding member is in the lower position, the window portion exposing the screw insertion hole when the sliding member is raised to an upper position. The front panel is provided with an interlocking switch for controlling the operation of a case unit such that, when the sliding member is raised to the upper position, pressure from the sliding member causes the interlocking switch to be switched on, and when the sliding member is in the lower position, the pressure is released and the interlocking switch is switched off. |
