PURPOSE: A device for sensing different sheets is provided to irradiate linear lights to a direction inclined with respect to a sheet in which adhesive paper is attached, thereby easily determining whether the adhesive paper is single or two or more sheets of the adhesive paper are overlapped. CONSTITUTION: A device for sensing different sheets comprises an inspection table(110), a light irradiating member, and a photographing device. The inspection table mounts a sheet in which adhesive paper is attached on a plane. The light irradiating member irradiates linear lights to a direction inclined with respect to the sheet on the inspection table. The photographing device is arranged on the top of the inspection table, thereby photographing reflected lights perpendicularly reflected from the adhesive paper and the sheet in which the liner lights are irradiated. |
