Abstract:
In a paper punch machine comprising a housing and a die assembly with a longitudinal slot for receiving paper to be punched by the die assembly, an improvement comprising a paper stop system, the paper stop system comprising:a paper stop having a stop portion extending over the paper-receiving slot of a die assembly and having a stop surface against which paper abuts when placed in said paper-receiving slot; a connection system movably connecting the paper stop to the machine so that the paper stop is movable on the housing parallel to the paper-receiving slot to a grossly-adjusted position; a securement system adapted to temporarily hold the paper stop in fixed relationship relative to the paper-receiving slot; a fine-tuning system operatively connected to said paper stop for moving said paper stop longitudinally from said grossly-adjusted position to a finely-adjusted position, wherein said fine-tuning system comprises a threaded member extending longitudinally and operatively engaging the paper stop so that turning the threaded member moves the paper stop longitudinally parallel to the paper-receiving slot, and the improvement further comprising an actuation system on an upper front surface of said housing near the paper-receiving slot and at an opposite end of paper-receiving slot from the paper stop, the actuation system comprising a slidable member that is separate from the paper stop that is movable longitudinally along said upper front surface, and an actuation button on an upper surface of the slidable member operatively connected to a switch for actuating punching by the machine, wherein the actuation button is adapted to be pushed down in a direction perpendicular to the longitudinal slot by a user's hand, and wherein the actuation system is adapted to be adjustable for use with different papers and for different users by the actuation system being slidable in a direction parallel to the longitudinal slot and lockable at various distances from said paper stop.
