ABSTRACT:
A dual-module hole-punching and binding machine includes a housing, a first hole-punching unit, a second hole-punching unit, a pressing unit, a measurement unit, an adjustment unit and a coil piece affixing unit. The first hole-punching unit and second hole-punching unit have a first cutting unit and a second cutting unit, respectively. Either cutting unit has a plurality of cutting members, which are aligned and equally spaced and may be used to punch holes in a stack of paper. The pressing unit has an adjustment member, which may move along an adjustment rod and may be used to adjust the pressing displacement of the pressing member. The measurement unit has a plurality of notches, which are equally spaced and parallel to each other. A user may use the widths of these notches to measure the thickness of a stack of paper. The adjustment unit may be used to adjust the depth that the paper stack is placed into the machine. The coil piece affixing unit may be used to hold an open coil piece so that the open coil piece may be inserted and fitted into a stack of paper with holes.
