ABSTRACT:
A safety system for a power stapler in which stapling of a set of sheets is actuated by inserting the set of sheets into the stapling jaws of the stapler, includes a large transparent upper plate mounted above the entrance to the stapling jaws and extending away from the stapling jaws by a distance greater than the length of a human finger, more than approximately 8 centimeters, and a lower plate below the entrance to the stapling jaws similarly extending, to prevent fingers from being inserted into the stapling jaws of the stapler. The upper and lower plates are spaced apart by a distance greater than the maximum thickness of the set of sheets to be stapled, to allow any set of sheets to be inserted into the stapling jaws from in between the upper and lower plates and be movable for alignment between the plates while being visible through the transparent upper plate. The plates may be pivotally mounted to the stapler so as to fold up into a compact vertical storage position closely adjacent to the stapler when not in use, in which position access to the stapling jaws is blocked.
