PURPOSE:To obtain reliable switching action with compact constitution, by arranging a magnetic lead switch element and its driving magnet with them opposed and spaced by a prescribed distance therebetween, and providing a movable body that can be introduced into the space between them and can form a short-circuit magnetic path in the space. CONSTITUTION:A stacker body A is provided with the magnetic lead switch element 1 connected to a prescribed control circuit, and the driving magnet 2 is opposed parallely to the switch element 1 with a prescribed space therebetween. The end section 3b is arranged in such a way that the section 3b can be moved into or away from the space between the element 1 and the magnet 2, and a controllably movable arm 3 is provided, so that the end section 3b may form the magnetic path bridge section of the driving magnet 2. When a sheet of paper enters the stacker body A and the oscillation of the controllably movable arm 3 becomes large, the magnetic path bridge section 3b enters between the switch element 1 and the driving magnet 2 to open the switch element 1, so that the movable arm 3 is moved in the opposite direction by the control section. By repeating this action, the sheet is folded along a prescribed line. |
