ABSTRACT:
A multi-hole punch and ruler combination which is especially adapted for storage in and use with a multi-ring binder. The ruler provides a receptacle for receiving the punched out paper chips, as well as a plurality of retention tabs and support tabs for securing the punch in the receptacle in a press fit engagement which may be readily released by the user when desired. The punch comprises relatively low profile upper and lower portions, the lower portion having a defined paper receiving area with front and side edge borders for accurately aligning the edge of the paper relative to the punch members. The lower portion also provides a plurality of cantilevered fingers for receiving the paper edge adjacent the punch holes through which punch members on the upper portion of the punch can protrude and cut or punch holes in the paper sheets received by the punch of the invention. These fingers hold the edge of the paper sheet to separate the sheet from the punch members after the sheet has been punched. The upper and lower portions of the punch are hinged in a press fit relation. The ruler has two conventional straight edge scales, one on each side or edge of the punch. One such scale provides a plurality of loose leaf ring holes so that the combined punch and ruler can be supported on the rings of a multi-ring binder.
