Abstract
An apparatus for inspecting plate-like bodies to inspect a side surface of a plate-like body with sheeted coating materials on a top side and bottom side of the plate-like body, is provided. The apparatus includes at least one light emitting unit configured to irradiate the side surface of the plate-like body with light. The apparatus includes at least one light receiving unit configured to receive light reflected with respect to the side surface of the plate-like body. The apparatus includes a conveying unit configured to move at least one among the light emitting unit and the plate-like body and to vary a position of the light on the side surface of the plate-like body, emitted by the light emitting unit. The apparatus includes a determining unit configured to determine whether the side surface of the plate-like body has a defect, by using the light emitted by the light emitting unit, upon occurrence of a condition under which the conveying unit varies the position of the light, on the side surface of the plate-like body, emitted by the light emitting unit.
