ABSTRACT:
In the left-and-right-direction center of the bottom portion of a staple loading chamber 5, there is formed an opening 6, the left-and-right-direction central portion of the upper surface of a staple guide table 7 is exposed through the opening 6, and on the two left and right sides of the opening 6, there are formed staple guide grooves 9L and 9R which respectively communicate with the staple guide table 7. A belt with a tab portion is bonded to and wound on a roll staple. If the roll staple with the belt is inserted into the staple loading chamber 5, a front lid 2 is closed and the belt is pulled forwardly while holding the tab portion thereof, then the belt comes loose, so that the front portion of the roll staple is guided into the staple guide grooves 9L and 9R and is then fed to a position located in front of the staple guide table 7. If the tab portion of the belt is pulled further, then the belt is peeled off the front portion of the roll staple, which completes the loading of the roll staple.
