Patent ID: 8231321

Claim:
A paper processing and punching apparatus for punching holes in a sheet of predetermined paper to discharge the sheet of paper, comprising: a paper-transferring section containing a first transfer path for transferring of paper one by one toward a predetermined position and a second transfer path to which a transfer route is switchable from the first transfer path; a punch processing section that receives the sheets of paper transferred by the paper-transferring section one by one and punches two or more holes for binding at one end of each received sheet; a paper-position-correcting means for correcting a position of the sheet of paper to be punched; a paper aligning unit that aligns the plurality of sheets of paper punched by the punch processing section and temporarily retains them; a bind processing section for binding the plurality of sheets of paper aligned by the paper aligning unit with a binding member to create the booklet, the bind processing section containing a moving mechanism that holds the binding member to fit the binding member through the punched holes; and controlling means for controlling the paper-transferring paper-transferring section, the punch processing section and the paper-position-correcting means, wherein the controlling means controls the paper-transferring section so as to decelerate and stop the transfer of the sheet of paper at the predetermined position on the first transfer path, to switch the paper transfer route, then, from the first transfer path to the second transfer path, and to deliver the sheet of paper in a reverse direction thereof, and the controlling means controls the paper-position-correcting means so as to correct the position of the sheet of paper before punching the sheet of paper, and wherein the moving mechanism rotates back and forth between a first position along the paper transfer direction of the paper aligning unit and a second position on a line intersecting with the transfer direction of the paper-transferring section to fit the binding member through the punched holes.
