摘要： The present invention provides a pinhole inspection apparatus for can bodies including a rotary plate having a penetrating through hole, a movable plate provided on a stationary frame opposite the rotary plate, a can body holding member that holds a can body, a photodetector that detects light leaking inside the can body, and a light source that irradiates an outer circumferential surface of the can body with light. The movable plate includes a ring plate attached to a front surface of a piston member, which has a penetrating hole in a central portion thereof, via a joint member. The ring plate is provided with a shield member formed by an annular member that is formed concentric to the penetrating hole. The shield member is brought into sliding contact with the rotary plate by a pressure application mechanism.

摘要： Provided is a pinhole inspection apparatus for can bodies capable of effectively preventing entrance of ambient light to a photodetector side through a gap between a movable plate and a rotating turret that may be formed due to a surface condition or the like. The pinhole inspection apparatus of the present invention includes: a rotating turret having a penetrating through hole; a movable plate provided on a stationary frame opposite the rotating turret; a can body holding member supporting a can body; a photodetector detecting light leaking inside the can body; and a light source irradiating the can body with light. The pinhole inspection apparatus is characterized in that a detour path formed by a pair of shield parts spaced apart a predetermined distance and opposite from each other is provided as a shield mechanism in an entire outer peripheral region of the rotating turret.
