发明名称 Paper punch with punched-hole reinforcing piece sticking mechanism
摘要 A paper punch sends out a tape carrying a number of punched-hole reinforcing pieces by the length of a single reinforcing piece interlockingly with the motion of a handle that raises and lowers a punching rod, sticking the reinforcing piece in the desired position of a sheet of paper placed on a base and, then, cutting a binding hole through the paper and reinforcing piece stuck thereon. The improvement is such that an insertion hole is provided in the handle to loosely pass through a horizontal pin that is attached to the punching rod so that the punching rod is kept from descending to perform a punching operation while the carrying tape is let out by the length of a single reinforcing piece in the early stage of the descending stroke of the handle. A pressing mechanism is provided so that the reinforcing piece supplied from the carrying tape into the desired position on the paper is firmly pressed against the paper before the punching rod cuts a hole therethrough. Accordingly, a binding hole is cut in the desired position of the paper and reinforcing piece after the reinforcing piece has been securely stuck in the desired position of the paper.
