Further, a lead-out port 4 for the lowermost sheet staple 1a is formed at the lower end of the front wall 2a of the storage section 2, and a guide piece 5 for guiding the upper face of the sheet staple 1 pulled out is provided in front of the lead-out port 4. Has been formed. further,
A guide groove 6 is provided vertically in the central portion of the rear wall of the storage portion 2.
However, the outlets 7 are formed at their lower ends.

Reference numeral 8 is a package. The packaging body 8 is formed by stacking a certain amount of sheet staples 1 stored in the storage portion 2 of the cartridge in a laminated state by a packaging means 9 such as paper or synthetic resin film, and can be stored in the storage portion 2. It is formed in size. Then, in the packaging means 9 of the packaging body 8, the outlet 4 of the storage portion 2 and the bottom opening portion 1 are provided.
Openings 11 and 12 (see FIG. 3) corresponding to 0 are formed, and the upper portion 13 is also open. It should be noted that these openings may be formed by cutting them from the perforations formed in the packaging means 9.

By the way, as shown in FIG. 3, the lowermost sheet staple 1a stored in the packaging body 8 is prevented from falling out of the bottom opening 12 of the packaging means 9 as shown in FIG. Fall prevention sheet 1 to prevent
4 are arranged. That is, the wrapping body 8 houses the sheet staple 1 in the wrapping means 9 together with the drop-preventing sheet 14. An opening 15 is also formed in the lower portion of the rear surface of the packaging means 9 for withdrawing the drop-preventing sheet 14. A projecting piece 16 is formed on the rear side of the captive prevention sheet 14.

It should be noted that an L-shaped holding piece 17 as shown by a dotted line in the figure may be formed on both sides of the drop-off prevention sheet 14 on the side of the protruding piece 16. When the captive sheet 14 is positioned inside the package 8, the holding piece 17 holds the outer side of the packaging means 9 and the bottom opening 12 expands to prevent the captive sheet 14 and the sheet staple 1 from being separated. Prevent it from falling off.

In the above structure, when the sheet staple 1 is loaded in the cartridge A, it is dropped into the storage portion 2 of the cartridge A while being wrapped in the package 8.
