An electronic device for optically checking an appearance of a product for defects includes a first checking device checking a plane of a product and a second checking device checking side surfaces of the product. The first checking device includes a first camera device, a second camera device, and first white and red light sources. The second checking device includes a third camera device, at least one second white light source, and at least one second red light source. When the first white light source or the first red light source are activated, the first and second camera device capture at least one image of a plane. When the second white light source or the second red light source are activated, the third camera device captures at least one image of a side surface.
