Abstract

A binding apparatus has a switching flapper 15 switching a feed path for feeding papers to either an upper discharge port or a lower discharge port, a discharge roller 20 provided on the upper discharge port, and a shutter 13, a stapler 14 and a discharge roller 12 provided on the lower discharge port. The discharge roller 12 can feed the papers in a direction opposite to a general paper feed direction, and the shutter 13 stops the papers on a specified position and positions the same when the papers are fed in the opposite direction. The stapler 14 staples the positioned papers. The discharge roller 12 presses the papers against the shutter 13, registers the papers, and discharges the papers in the general paper feed direction after the papers are stapled. Consequently, a miniature paper binding apparatus having a simple structure can be provided.

Claims

1. A binding apparatus comprising:

first discharge means for discharging a single or plurality of first papers;

positioning means for stopping said single or plurality of first papers and a second paper on a specified position and positioning said single or plurality of first papers and said second paper;

binding means for binding said single or plurality of first papers and said second paper positioned on said position;

second discharge means located under said first discharge means for discharging said second paper and thereafter pressing said second paper against said positioning means while pressing said single or plurality of first papers discharged by said first discharge means against said positioning means and discharging said single or plurality of first papers and said second paper after said single or plurality of first papers and said second paper are pressed by said pressing means; and

switching means for switching a path for feeding said single or plurality of first papers or said second paper toward either said first discharge means or said second discharge means.

2. The binding apparatus according to claim 1, wherein said second discharge means changes feeding force for said single or plurality of first papers and said second paper when pressing said single or plurality of first papers and said second paper against said positioning means and when discharging said single or plurality of first papers and said second paper bound by said binding means.

3. The binding apparatus according to claim 1, wherein said second discharge means feeds said single or plurality of first papers and said second paper by pressing ends of said single or plurality of first papers and said second paper when discharging said bound single or plurality of first papers and said second paper.

4. The binding apparatus according to claim 1, wherein said second discharge means has a roller provided with a projection substantially perpendicular to the circumference thereof.

5. The binding apparatus according to claim 1, wherein said positioning means makes said second paper pass when said second paper is discharged.

6. The binding apparatus according to claim 1, further comprising punching means for punching a hole on a specified position of said positioned single or plurality of papers and said second paper.
