Summary:An electric punch for automatically punching holes in documents and the like is provided that allows the spacing between the holes to be selectively set at either 70 mm (U.S. standard) or 80 mm (European and Japanese standard) by forming a bend midway of the length of operating arms of respective perforating members so that forward and rearward portions of the operating arms are laterally offset in parallel by a prescribed distance and clamping the operating arms with two supports of different width, thereby enabling the punched hole spacing to be selectively changed by exchanging the left and right perforating members.
