VISUAL EXAMINATION APPARATUS FOR RESIN MOLDED ARTICLE AND VISUAL EXAMINATION METHOD FOR THE RESIN MOLDED ARTICLE

PROBLEM TO BE SOLVED: To suppress an installation space to be compact, without having to use too complex a mechanism, in the visual examination of an inspection target. SOLUTION: In the visual examination apparatus, caps C becoming inspection targets are placed on a transparent plate 12, in a matrix form, and the caps C in respective ranks are fed along the surface of the transparent plate 12, while being pushed by pusher rods 14c. During this feed period, the inner surfaces of the caps C are imaged from the area under the transparent plate 12 by inner surface inspection cameras 16. Next, the caps C are fed to the turret table 32 of a transfer part 30, through a first belt conveyor 18 and a second belt conveyor 20 to be received in pockets 34 one by one. The transfer part 30 transfers the caps C in the rotating direction of the turret table 32, in a state where the inner surfaces of the caps C are held and each of the caps C is rotated, at an inspection position in a thrust-up state. At this time, each of the caps C is laterally imaged by an outer peripheral surface inspecting camera 42. Furthermore, each of the caps C is imaged from above by a top surface-inspecting camera 40.
