摘要： An automatic hole punch is disclosed for creating holes in a sheave of sheet material. The automatic hole punch is preferably user-selectable between punching modes, such as two-hole and three-hole modes. A motor (54) is coupled to a camshaft (74) by a gear train (62). The camshaft (74) carries a plurality of cams (90) each having an associated punch (86). As the camshaft (74) rotates, the cams (90) sequentially drive corresponding punches (86). However, depending on the selected modality, one or more punches (86) may be idle by not being engaged with their respective cams (90), thus resulting in varying combinations of driven punches (86) resulting in different hole patterns. Finally, a spacer (130) can be inserted into a material receiving slot (38) for adjusting the relative positioning of the material to the punches (86) to properly position the hole pattern along an edge of the material to be punched.
