Abstract

A staple-refill 11 is provided with: a casing 12 in which a plurality of sheet-type connected staples 10 are stacked; a staple inserting port 14 ; a staple discharge port 16 ; a cover member 15 which covers the sheet-type connected staples 10 in the casing 12 from a side of the staple inserting port 14 ; and a notch portion 18 formed in the casing 12 and extending from an edge of the staple inserting port 14 in an insertion direction.

First claim

What is claimed is:

1. A staple-refill comprising:
a casing in which a plurality of sheet-type connected staples are stacked and accommodated;
a staple inserting port which is formed in the casing and through which the sheet-type connected staples are inserted in the casing in an insertion direction;
a staple discharge port which is formed in the casing and from which the sheet-type connected staples in the casing are discharged;
a cover member which covers the sheet-type connected staples in the casing from a side of the staple inserting port;
a guide boss formed in the cover member;
a guide portion which is formed in the casing and extending in the insertion direction, the guide boss being engaged with the guide portion to guide the cover member in the insertion direction; and
a notch portion formed in a side of the casing in which the staple discharge port is formed and having an edge continuous with and extending from an edge of the staple inserting port in the insertion direction,
wherein the cover member is disposed in the casing such that the notch portion does not overlap with the cover member as seen in the insertion direction,
wherein the staple inserting port is formed on one of two surfaces of the casing which are perpendicular to the insertion direction,
wherein the staple discharge port is formed on another surface of the casing including the insertion direction and a width direction in which each of staples of the sheet-type connected staples extends,
wherein the notch portion is formed between the staple discharge port and the staple inserting port in the insertion direction,
wherein the notch portion includes a bottom end at an end of the notch portion in the insertion direction at a side of the staple discharge port,
wherein the casing includes a wall defining the other of said two surfaces perpendicular to the insertion direction, and
wherein a dimension of the cover member in the insertion direction is larger than a length between a face of the wall in a side of the staple inserting port and the bottom end of the notch portion in the insertion direction.

2. The staple-refill according to claim 1 , wherein the guide boss includes a first boss and a second boss respectively formed on opposed end faces of the cover member in a width direction perpendicular to the insertion direction, and
wherein the guide portion includes a first guide part and a second guide part respectively formed on side surfaces of the casing which are opposed to each other in the width direction.

3. The staple-refill according to claim 2 , wherein the cover member is provided with an additional guide boss on an end face of the cover member between the said opposite end faces, and
wherein the casing is provided with an additional guide portion extending in the insertion direction, wherein the additional guide boss engages with the additional guide portion.

4. The staple-refill according to claim 2 , wherein the notch portion is formed on at least one of said side surfaces of the casing on which the first guide part or the second guide part is formed.

5. The staple-refill according to claim 1 , wherein the notch portion includes an opening thorough which a push lever for pressing the sheet-type connected staples in the casing via the cover member at a side of a stapling machine or a cartridge passes when the casing is attached to or detached from the staple-refill to/from a main-body of the stapling-machine or the cartridge to be attached to or detached from the main-body of the stapling machine.

6. The staple-refill according to claim 1 , wherein the notch portion is structured such that a push lever passes through an opening portion of the notch portion, in an attaching/detaching operation of the staple-refill to/from a main-body of a stapling-machine or a cartridge to be attached to or detached from the main-body of the stapling machine, and
wherein the push lever is provided at a side of the stapling-machine main-body or the cartridge, and adapted to press the sheet-type connected staples in the casing via the cover member.

7. The staple-refill according to claim 1 , wherein the guide portion comprises a guide hole, and
wherein the guide boss penetrates through the guide portion to protrude outward, and the guide boss engages with a positioning concave portion of a mounting object that accommodates the casing, the positioning concave portion being positioned at a position corresponding to the guide boss.

8. The staple-refill according to claim 1 , wherein the cover member is provided with a check claw on a peripheral portion thereof, and
wherein the casing is provided with a check groove which is engaged with the check claw to prevent the cover member from moving to the staple inserting port.

9. A staple-refill comprising:
a casing in which a plurality of sheet-type connected staples are stacked and accommodated;
a staple inserting port which is formed in the casing and through which the sheet-type connected staples are inserted in the casing in an insertion direction;
a staple discharge port which is formed in the casing and from which the sheet-type connected staples in the casing are discharged in a discharge direction;
a cover member which covers the sheet-type connected staples in the casing from a side of the staple inserting port;
a guide boss formed in the cover member;
a guide portion which is formed in the casing and extending in the insertion direction, the guide boss being engaged with the guide portion to guide the cover member in the insertion direction; and
a notch portion formed in a side of the casing in which the staple discharge port is formed and having an edge continuous with and extending from an edge of the staple inserting port in the insertion direction,
wherein the staple inserting port is formed on one of two surfaces of the casing which are perpendicular to the insertion direction,
wherein the staple discharge port is formed on another surface of the casing extending in the insertion direction and a width direction in which each of staples of the sheet-type connected staples extends,
wherein the notch portion is formed between the staple discharge port and the staple inserting port in the insertion direction,
wherein the notch portion includes a bottom end in the insertion direction at a side of the staple discharge port,
wherein the bottom end of the notch portion positions in the insertion direction between the staple discharge port and a center of the another surface of the casing in the insertion direction,
wherein the cover member is disposed in the casing such that the notch portion does not overlap with the cover member as seen in the insertion direction.

10. The staple-refill according to claim 9 ,
wherein the casing includes a wall defining the other of said two surfaces perpendicular to the insertion direction,
wherein a dimension of the cover member in the insertion direction is substantially the same with a length between a face of the wall in a side of the staple inserting port and the bottom end of the notch portion in the insertion direction.

11. The staple-refill according to claim 9 ,
wherein the notch portion is formed have the edge continuous with the edge of staple inserting port such that the staple inserting portion is more easily deformed.

12. The staple-refill according to claim 9 ,
wherein the casing includes a front wall, a rear wall, side walls and a bottom wall to define a space for accommodating the sheet-type connected staples,
wherein the notch portion is formed in the front wall to have the edge continuous with the edge of staple inserting port such that the side walls are more
