Abstract
A sheet finisher for automatically stapling, punching, folding or otherwise finishing a stack of sheets sequentially driven out of an image forming apparatus and positioned is disclosed. The finisher is capable of finishing the sheets at any desired position in an intended direction of sheet transport and in a direction perpendicular thereto. A device for driving the finisher is simple in construction.
Claims7
A sheet finisher for finishing at least one sheet introduced into a body thereof and conveyed within said body, said sheet finisher comprising:
- sheet truing means for positioning the sheet at a truing position in an intended direction of sheet transport and a direction perpendicular thereto;
- a clamp member for clamping the sheet positioned by said sheet truing means at said truing position;
- finishing means for finishing the sheet at a position difference from said truing position;
- clamp member drive means for shifting the sheet away from said truing position until a part of said sheet arrives at said finishing means, and for positioning said sheet such that a position of said sheet relative to said finishing means is variable in a direction in which said sheet is shifted;
- and
- positioning means for moving said finishing means in a direction perpendicular to said direction in which said sheet is shifted, and positioning said finishing means at a desired position in said direction in which said finishing means is moved.
A sheet finisher for finishing a plurality of sheets sequentially introduced into a body thereof and conveyed within said body, said sheet finisher comprising:
- sheet truing means for positioning the sheets at a truing position in a longitudinal direction in which said sheets are transported and a lateral direction perpendicular to said longitudinal direction;
- a separate stapler comprising a stapler body and a clincher separate from and facing each other, wherein a portion of said stapler body and a portion of said clincher for stapling the sheets hold said sheets brought to said truing position therebetween for stapling said sheets at substantially a center of said sheets in said longitudinal direction;
- a unitary stapler comprising a stapler body and a clincher operatively connected to each other, and for stapling the sheets positioned by said sheet truing means at one edge of said sheets in said longitudinal direction;
- and
- unitary stapler drive means for moving said unitary stapler in said lateral direction relative to the sheets, and positioning said unitary stapler at a desired position.
