PURPOSE:To enable set detection of a plurality of guide members by a single switch, by constituting the title device so that an elastic member is provided on a guide member which is removed after an opening operation of a maintenance door, a safety switch is turned ON at the time of closing a door by interlocking with an opening and closing the door and an apparatus is suspended at the time of turning-OFF of the safety switch. CONSTITUTION:A protrusion 33 is formed on the undersurface of a maintenance door 30. Then a leaf spring 34 is fitted to a guide member 31 by fixing one end 34a along a horizontal direction. In the leaf spring 34, the other end 34a is deformed elastically to a pressed-down position from a standstill position by the protrusion 33 when a maintenance door is fitted and the other end 35b of the leaf spring 35 whose one end is fixed to the lower guide member 32 is pressed down. With this construction, a switch 36 is turned ON by the other end 35b. Therefore, when the door 30 and the upper and lower guide members 31, 32 are missing, the switch 36 is not turned ON, an OFF condition is held and an apparatus is suspended. |
