A container for a plurality of thin plates has a driving unit for moving one of a pair of magnetic members, at least one of which is a magnet, embedded in a container body and contained in a chamber in a lid, respectively, to selectively produce attractive and non-attractive magnetic conditions between the first and second magnetic members. In one embodiment, the driving unit includes a rotatable plate, and an arm having one end attached to the rotatable plate and the second end attached to the movable magnetic member to move the movable magnetic member in response to rotation of the rotatable plate. In a second embodiment a parallel movement link has a long groove for engaging a pin provided on the rotatable plate; a magnetic member supporting link has a first end attached to one end of the parallel movement link and has its second end attached to the movable magnetic member. In a third embodiment the rotatable plate has a first bevel gear meshing with a second bevel gear on a shaft supporting the movable magnetic member.
