STICKER POSITION INSPECTING DEVICE

摘要

PURPOSE:To provide a device for ensuring inspection of displacement of an adhesive tape adhered by obtaining the image of the transparent adhesive tape stuck to a paper box with the clear end. CONSTITUTION:The device is to inspect whether there is a shift between the position of a transparent adhesive tape 2 stuck to a face and its predetermined position. Either one of a face or the surface of the transparent adhesive tape 2 is an irregular reflection plane to incident light and the other is a regular reflection plane to incident light. The device consists of a laser beam source 3 to apply slit laser beam Ls to a predetermined position, a scattering plate 4 to receive the reflected laser beam Ls, an image pickup device 5 to pick up light scattered by the scattering plate 4 and an image processor 6 to make shift judgement from the position of an image obtained by the image pickup device 5 in a screen.
