PURPOSE:To simplify inspection work, by inspecting the first surface of a product to be inspected, which is fed from a feeding device one by one during the time the product is moved by a first inspecting conveyer, turning over the product, and inspecting the other surface during the time the product is moved by a second inspecting conveyer. CONSTITUTION:A product to be inspected 3 is taken out by a sucking board 4 one by one and mounted and moved on a rear conveyer 5a of a first inspecting conveyer 5 and then on a front conveyer 5b. During this period, the printed state of one surface of the product is inspected. After the inspection, the product 3 falls from the front end of the front conveyer 5b in a suspended state and mounted on a reversing conveyer 6 in a reversed state. Then, the product is mounted on a second inspecting conveyer 8 under the intact state and moved forward. During this period, the other surface of the product 3 is inspected. Then it is mounted on a discharge conveyer 10 and discharged. In this way, since the product can be automatically turned over after the inspection of one surface and the other surface can be inspected, the inspection work of the products such as cards can be simplified.
