Abstract
A staple cartridge that sequentially draws out rolled staple band material from the staple storage portion includes regulating device that touches the stacked surface of the rolled staple band to regulate the widening and unraveling of the stacked surface. The regulating device is capable of regulating the widening of the stacked surface of the staple band material in the roll diameter direction even during vibration of the cartridge. This minimizes the phenomenon of the staple band material biting to or catching on the staple cartridge.
Claims22
A staple cartridge comprising:
- a staple storage portion for storing a rolled band of staples linked in a sheet, the staple storage portion including an inner wall;
- and
- a regulating means distinct from the inner wall for engaging a stacked surface of the rolled band of staples and regulating the spreading out of the stacked surface to thereby minimize the likelihood of the rolled band of staples becoming unwound and expanding within the staple storage portion;
- wherein the regulating means includes a regulating plate between the inner wall of the staple storage portion and the stacked surface of the rolled band of staples, and wherein the regulating plate rotates as the rolled band of staples is drawn out of the staple storage portion.
A stapler comprising:
- a frame, and
- a staple cartridge removably coupled to the frame, the staple cartridge including
- a staple storage portion for storing a rolled band of staples linked in a sheet, the staple storage portion including an inner wall;
- and
- a regulating means distinct from the inner wall for engaging a stacked surface of the rolled band of staples and regulating the spreading out of the stacked surface to thereby minimize the likelihood of the rolled band of staples becoming unwound and expanding within the staple storage portion;
- wherein the regulating means includes a regulating plate between the inner wall of the staple storage portion and the stacked surface of the rolled band of staples, and wherein the regulating plate rotates as the rolled band of staples is drawn out of the staple storage portion.
A staple cartridge comprising:
- a staple storage portion for storing a rolled band of staples linked in a sheet, the staple storage portion including an inner wall;
- and
- a regulating means distinct from the inner wall for engaging a stacked surface of the rolled band of staples and regulating the spreading out of the stacked surface to thereby minimize the likelihood of the rolled band of staples becoming unwound and expanding within the staple storage portion;
- wherein the regulating means is biased toward the stacked surface of the rolled band of staples.
