Abstract
Official abstract text for this publication.
A refill case is provided with: an accommodating part ( 2 ) for accommodating staple-sheets ( 1 ); a staple pressing member ( 4 ) for pressing a top of the staple-sheets ( 1 ); locking saw-toothed portions ( 6 a, 6 b ) having saw-toothed shapes; and return-preventing claws ( 5 ) formed ends of the staple pressing member ( 4 ) and engaged with the locking saw-toothed portions. A phase of the saw-toothed shape of the right locking saw-toothed portion is shifted from a phase of the saw-toothed shape of the left locking saw-toothed portion.
First claim

What is claimed is: 1. A refill case comprising: an accommodating part in which staple-sheets, each of which is formed by connecting straight staple members in a sheet shape, are stacked and accommodated; a staple pressing member which is arranged inside the accommodating part and configured to press a top of the staple-sheets in the accommodating part; a right locking saw-toothed portion formed in a right inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along a stacking direction of the staple-sheets; a left locking saw-toothed portion formed in a left inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along the stacking direction; a right return-preventing claw formed at a right end of the staple pressing member and configured to engage with the right locking saw-toothed portion; and a left return-preventing claw formed at a left end of the staple pressing member and configured to engage with the left locking saw-toothed portion, wherein the right return-preventing claw positions in the same position in the stacking direction with the left return preventing claw, and wherein a phase of the saw-toothed shape of the right locking saw-toothed portion is shifted from a phase of the saw-toothed shape of the left locking saw-toothed portion. 2. A refill case comprising: an accommodating part in which staple-sheets, each of which is formed by connecting straight staple members in a sheet shape, are stacked and accommodated; a staple pressing member which is arranged inside the accommodating part and configured to press a top of the staple-sheets in the accommodating part; a right locking saw-toothed portion formed in a right inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along a stacking direction of the staple-sheets; a left locking saw-toothed portion formed in a left inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along the stacking direction; a right return-preventing claw formed at a right end of the staple pressing member and configured to engage with the right locking saw-toothed portion; and a left return-preventing claw formed at a left end of the staple pressing member and configured to engage with the left locking saw-toothed portion, wherein the right return-preventing claw positions in the same position in the stacking direction with the left return preventing claw, and wherein a phase of the saw-toothed shape of the right locking saw-toothed portion is Shifted by ½ pitches from a phase of the saw-toothed shape of the left locking saw-toothed portion. 3. A refill case comprising: an accommodating part in which staple-sheets, each of which is formed by connecting straight staple members in a sheet shape, are stacked and accommodated; a staple pressing member which is arranged inside the accommodating part and configured to press a top of the staple-sheets in the accommodating part; a right locking saw-toothed portion formed in a right inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along a stacking direction of the staple-sheets; a left locking saw-toothed portion formed in a left inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along the stacking direction; a right return-preventing claw formed at a right end of the staple pressing member and configured to engage with the right locking saw-toothed portion; and a left return-preventing claw formed at a left end of the staple pressing member and configured to engage with the left locking saw-toothed portion, wherein a phase of the saw-toothed shape of the right locking saw-toothed portion is the same with a phase of the saw-toothed shape of the left locking saw-toothed portion, and wherein the right return-preventing claw is formed in a position shifted from the left return-preventing claw in the stacking direction. 4. A refill case comprising: an accommodating part in which staple-sheets, each of which is formed by connecting straight staple members in a sheet shape, are stacked and accommodated; a staple pressing member which is arranged inside the accommodating part and configured to press a top of the staple-sheets in the accommodating part; a right locking saw-toothed portion formed in a right inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along a stacking direction of the staple-sheets; a left locking saw-toothed portion formed in a left inner wall of the accommodating part and having a saw-toothed shape with a plurality of peaks and a plurality of troughs alternatively arranged with each other along the stacking direction; a right return-preventing claw formed at a right end of the staple pressing member and configured to engage with the right locking saw-toothed portion; and a left return-preventing claw formed at a left end of the staple pressing member and configured to engage with the left locking saw-toothed portion, wherein a phase of the saw-toothed shape of the right locking saw-toothed portion is the same with a phase of the saw-toothed shape of the left locking saw-toothed portion, and wherein the right return-preventing claw is formed in a position shifted by ½ pitches of said saw-toothed shape in the stacking direction from the left return-preventing claw.
