ABSTRACT:
The present invention is an ergonomic paper punch, which includes a die body, a press body, and a plurality of punch heads. The die body and the press body are pivotally connected along an axis for a rocking motion, with the die body and press body forming a "V" shape when viewed in a cross-section perpendicular to the axis. The die body has a die base with a plurality of die holes, an equal number of brackets with guide holes, and a paper reception region in between the base and brackets. A portion of the upper surface of the press body is covered by a resilient, textured surface. The underside of the die base has a region for holding the punch-outs that is covered by a resilient tray. The tray is secured to the top surface of the die base, extends around the die base, and covers the punch-out holding region. The tray is completely detachable from the punch-out holding region so the region can be emptied, but remains attached to the die base so as to not get lost. The tray contains a closable aperture that can also be used to empty the punch-out holding region. The center section of the lower rear edge of the tray is curved, rather than squared off.
