A refill case comprising:
- an accommodating part in which staple-sheets, each of which is formed by connecting straight staple members in a planar sheet shape, are stacked in an up/down direction and accommodated;
- a front wall extending in the up/down direction;
- a leading-out port formed in the front wall, and from which a lowermost staple-sheet of the stacked staple-sheets in the accommodating part is led out forward;
- and
- an eaves part formed in an upper side of the leading-out port,
- wherein the eaves part includes a front end positioned in a front side of the front wall and a lower surface formed between the front end and the front wall such that the eaves part extends from the front wall.
A staple cartridge comprising:
- a pressing part configured to insert in a space defined between an engaging part protruding from a front wall of a refill case and an eaves part protruding from the front wall of the refill case, and configured to engage with the engaging part protruding from the front wall of the refill case;
- and
- a protrusion formed on the pressing part and configured to face a lower surface of the eaves part of the refill case;
- wherein the protrusion is structured so that a gap between the lower surface of the eaves part and the protrusion is smaller than a thickness of a staple when the refill case is attached to the staple cartridge and the pressing part is inserted in the space defined between the engaging part and the eaves part.
