The chip of the staple leg cut by the cutter unit 12 is guided into the chip containing portion 23 of the staple cartridge 20 by a chute 22 formed on the cutter unit 12. The chip of the staple leg is collected in the staple cartridge 20.
Claims9
A staple cartridge comprising:
- a staple containing portion for containing a number of staples;
- and
- a chip containing portion for containing a chip of a cut staple leg,
- wherein the staple containing portion and the chip containing portion are formed integrally so that the chip containing portion is arranged at a position opposed to a cutter unit of a stapler, and
- wherein the chip containing portion formed integrally with the staple containing portion is adapted to mount attachably and detachably towards and away from the position opposed to the cutter unit of the stapler, such that when the number of staples in the staple containing portion is depleted and the staple containing portion is detached with the integrally formed chip containing portion away from the cutter unit of the stapler, the cut staple leg in the chip containing portion is removed simultaneously with the staple containing portion from the position opposed to the cutter unit.
A staple leg chip processing apparatus comprising:
- a strike mechanism portion for striking out a staple to sheets;
- a cutter unit for cutting a leading end portion of a staple leg projected to a back face side of the sheets;
- a clincher mechanism portion operably supported to be proximate and remote to and from the strike mechanism portion and for bending the staple leg along the back face of the sheets;
- a chip containing portion for containing a chip of the cut staple leg and arranged at a position opposed to the cutter unit;
- and
- a chute formed at the cutter unit for guiding the chip to the chip containing portion;
- wherein the chip containing portion is provided integrally with a staple containing portion for containing the staple to form a staple cartridge mounted attachably and detachably to and from the position opposed to the cutter unit such that when the staples in the staple containing portion are depleted and the staple containing portion is detached with the integrally formed chip containing portion, the cut staple leg in the chip containing portion is removed from the position opposed to the cutter unit simultaneously with the staple containing portion.
