PROBLEM TO BE SOLVED: To provide a dropping plate for surely dropping a punched part. SOLUTION: This dropping plate 1 is composed of a support plate 1a composed of plywood, and a metallic plate 1b composed of SUS (stainless steel). A punched corrugated board 11 composed of a product part 12 and a circular punched part 13 is placed on the metallic plate 1b of the dropping plate 1. A punched hole 5a is formed in the support plate 1a, and a punched hole 5b is formed in the metallic plate 1b. A diameter of the punched hole 5a of the support plate 1a is set larger than a diameter of the punched hole 5b of the metallic plate 1b, and two projection parts 5c projecting in the punched hole 5b are arranged in the punched hole 5b of the metallic plate 1b. Since both of the diameters of the punched hole 5a and the punched hole 5b are larger than a diameter of the punched part 13, the punched part 13 is easily dropped downward by projection of a projecting pin 16. Since the two projection parts 5c are projected below a peripheral edge part of the punched part 13, the punched part 13 is not sprung up on the corrugated board 11. COPYRIGHT: (C)2005,JPO&NCIPI
