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.

1. A container for a plurality of thin plates comprising:a container body having an interior for receiving and supporting the plurality of thin plates; a lid for being detachably mounted on the container body for sealing the interior of the container body; a first magnetic member provided in the container body; a second magnetic member provided in the lid; one of said first and second magnetic members being a magnet; a rotatable plate; and an arm having one end attached to the rotatable plate and the second end attached to a movable magnetic member of said first and second magnetic members to move the movable magnetic member in response to rotation of the rotatable plate between first and second positions producing first and second magnetic conditions; said first magnetic condition being to generate a magnetic attractive force between the first and second magnetic members sufficient to secure the lid to the container body, and said second magnetic condition being to release attractive magnetic force between the first and second magnetic members sufficient to allow the lid to be freely removed from the container body.
