<P>PROBLEM TO BE SOLVED: To improve an insertion stability of a coil end when the end of a helical coil is inserted in a hole part of a paper stack. <P>SOLUTION: The coil binding apparatus includes a coil-forming mechanism 20 which forms and draws out a helical coil 11d for binding of the paper stack, and a binding mechanism 40 which binds punched holes 3a of the paper stack 3 by the helical coil 11d drawn out from the coil-forming mechanism 20. The binding mechanism 40 has at least a coil end-inserting mechanism 80 which inserts the end of the helical coil 11d into the first punched hole 3a of the paper stack 3 upon receipt of the helical coil 11d drawn out from the coil-forming mechanism 20. The end of the helical coil 11d inserted with a good reproducibility into the first punched hole 3a of the paper stack 3 can be smoothly inserted into the second and subsequent punched holes 3a of the paper stack 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
