Abstract
In order to inspect a floppy disk casing for projection of a liner beyond an edge of the casing, a light beam is projected in the direction of the thickness of the casing so that at least a part of the light beam passes near the edge of the casing on the side of the edge opposite to the casing, and whether the liner projects beyond the edge is determined on the basis of the amount of light received by a light receiving means disposed in a direction in which, when a portion of the liner projects beyond the edge, the light beam is scattered by the projecting portion of the liner and which deviates from the direction of straight travel of the light beam.
