## Abstract

A binder cartridge (51) that can accommodate a large number of binders (61), which are connected in parallel to each other by an engaging mechanism. A right angle crank-shaped guide groove (55) is formed in a gate portion (54) at the front end of the binder cartridge. A binder in the front row of the binder cartridge is moved by a binder lateral movement mechanism (7) along the crank-shaped guide groove in the lateral direction and is separated from the other binders. A pair of upper and lower pushers (12, 13) of a bind mechanism portion (5) pinch division ring portions of the binder in the vertical direction and insert the division ring portions into a punch hole formed on the sheets of paper.

## Claims

### Claim 1

A bind processing method in which sheets of loose leaf paper are bound with a binder, the sheets of loose leaf paper having a plurality of punch holes formed along one side of the sheets of paper and the binder comprising a continuous rectangular bar-like spine portion and a plurality of hinged first and second division ring portions arranged at regular intervals along both long sides of the continuous rectangular bar-like spine portion, the spine portion being interposed between the first and second division ring portions, the method comprising:
symmetrically driving pairs of first and second pushers so as to close the first and second division ring portions of the binder;
engaging forward end portions of the first division ring portions with forward end portions of the second division ring portions within the punch holes formed on the sheets of loose leaf paper; and
separating one binder from a stack of a plurality binders, wherein the one binder which is separated is used as said binder for binding the sheets of papers.

### Claim 2 (depends on 1)

The bind processing method according to claim 1, wherein each of the pairs first and second pushers comprises two sets of the pairs of first and second pushers,
the two sets of pairs first and second pushers are arranged in a longitudinal direction,
one set of the pair of first and second pushers pinch back face sides of the first and second division ring portions of the binder so as to rotate the first and second division ring portions in a closing direction, and
another set of the pair of first and second pushers pinch forward end sides of the division ring portion of the binder so as to engage the forward end portions of the opposing first and second division ring portions with each other.

### Claim 3 (depends on 1)

The bind processing method according to claim 1, further comprising:
supporting the sheets of paper to be bound in a sheet table, and
advancing and retreating the sheet table toward the binder when the pairs of first and second pushers conduct binding, so that generation of abrasion between the division ring portion and inner wall faces of the punch holes can be suppressed when the division ring portions of the binder proceeds into the punch hole on the sheets of paper.
