Abstract
An apparatus for punching holes is provided. The apparatus may include a base movable from a first position to a second position and first and second punch assemblies attached to and movable with the base. The punch assemblies may each include parallel punches movable relative to the base and having an end. The apparatus may include first and second cams fixed to a rotatable shaft and having an engagement portion for engagement with the ends of the respective punches at a predetermined rotation position of the shaft. When the base is in the first position, rotation of the shaft to the predetermined rotation position may cause movement of only one of the punches relative to the base. When the base is in the second position, rotation of the shaft to the predetermined rotation position may cause movement of only the other punch of the punch assemblies.
