Abstract
A punching apparatus for a sheet media comprises a base and a handle actuator. The base comprises a first impression head that defines a first image-forming pattern and a second impression head that defines a second image-forming pattern. The base further comprises a first impression head protrusion having a first height and a second impression head protrusion having a second height. The handle actuator hingedly couples to the base. The handle actuator moves between a first position, a second position, and a third position. A limiting member contacts the first impression head protrusion when the handle actuator is moved to the second position, and the first impression head moves to a sheet media forming position. The limiting member contacts the second impression head protrusion when the handle moves to the third handle position, and the first and the second impression heads move to the sheet media forming position.
