ABSTRACT:
The invention is of an improved staple removing and retaining apparatus. The remover has a two-part pry-bar type removing member, both members of which initially are inserted below the cross-member of an installed staple, but a part of which then, upon actuation of the remover, lifts the staple from paper level. The removed staple is trapped in a magnetized trap compartment. The paper is not damaged because the non-moving component of the pry-bar assembly remains flush with the paper, prevents any distractive force being applied thereto, and deforms the staple cusps during removal to travel solely through the originally formed holes in the paper. Applicant's remover eases staple removal, prevents paper damage, and contains removed staples which might otherwise fall into and damage expensive computer and photocopy equipment.
