Document Type and Number:
Japanese Patent JPS6254697
Kind Code:
A
Abstract:
A hand-operated punch is formed of molded parts which interfit for easy and rapid assembly and disassembly. This feature is particularly useful if there are paper jams. A handle hooks under a wall of the base. Depressing the handle forces downward a transverse bar recessed to accept the upper ends of the male punch elements, which are spring-biased to travel with the transverse bar. The punch elements reciprocate within a die bar detachably connected to the base. The die bar is formed with a throat for insertion of papers to be punched. The front edge of the base is formed with a transverse groove to accept a male binder element during assembly of a book comprised of the punched paper.
