Hole punch element

A hole punch device for creating holes in paper sheets within the device, comprising:

• a substantially cylindrical punch pin having a pin axis;
• a frame guiding the punch pin along the pin axis, wherein the frame includes a base having a surface;
• a slot in the frame, wherein the slot includes a ceiling and a floor, the floor including an anvil cavity and a floor portion for a paper path with an offset surface contour, the offset being with respect to a distance from the ceiling, and wherein the floor coincides with the surface of the base of the frame;
• the paper sheets normally extending remotely from the pin in a perpendicular direction to the pin axis;
• and
• wherein the punch pin at a lowest position at least partially extends into the anvil cavity, and the punch pin presses the paper within the slot against the base so that the paper sheets, exclusive of a location within the anvil cavity, are forced to bend at the pin in relation to the perpendicular direction to follow the offset contour of the slot;
• and
• wherein the offset surface contour of the slot floor, exclusive of the anvil cavity, includes an upper floor segment and a lower floor segment, and an angled floor segment joins the upper floor segment to the lower floor segment, and the punch pin in the lowest position extends into the anvil cavity through the angled floor segment, and the paper sheets are biased to become bent at a location of the angled floor segment.
