Abstract

A hole punch apparatus with a jam release clip coupled to a push rod and a punch pin, wherein the push rod passes through a hole formed in a side of the clip, and wherein the punch pin is secured to the clip by a pair of parallel fingers at one end of the clip that engage two flat grooves formed in the sides of the punch pin. A handle of the hole punch apparatus pivots about a pivot rod, which handle front end is linked to the punch pin via the jam release clip. Pressing down on the handle advances the punch pin to cut a hole in a paper stack held inside a paper slot, and lifting up on the handle withdraws the punch pin out of the paper stack.

Abstract

A desktop hole punch device for punching holes in stacked sheet media such as paper is disclosed. The hole punch device includes at least one adjustable, laterally extending arm having markings thereon indicating standard office paper sizes. The markings are visible to the user through a window in the device. An edge guide at the distal end of the arm aligns the stack of sheet media and a curved page lifter extending from the edge guide reverses the natural curl in the paper stack for better and more precise hole punching.
