Staple cartridge and staple sheet pack.

摘要

An object of the present invention is to provide a staple cartridge usable for a motor driven stapler wherein the staple cartridge can repeatedly be used not only with substantial reduction of a quantity of disposable waste material but also with effective saving of a useful source. The bottom surface of a staple cartridge 11 is kept open so as to allow a staple sheet holder 13 to be detachably charged in a staple sheet holder 13. A predetermined number of staple sheets 2, 2 --- are received in the staple sheet holder 13 in the laminated state so that a laminated structure of staple sheets 2 is supplied to a user in the form of a staple sheet pack 12 bounded by a band 14. Engagement holes 23 are formed on the staple sheet holder 13, and a lock lever 24 is disposed so as to allow engagement pawls 24a of the engagement lever 24 to be engaged with the engagement holes 23. As the staple sheet pack 12 is inserted into the staple cartridge 11 through an opening portion on the bottom surface of the staple cartridge 11, the engagement pawls 24a of the lock lever 24 are brought in engagement with the engagement holes 23 so as to allow the staple sheet pack 12 to be firmly held in the staple cartridge 11 in the locked state. After the band 14 is disconnected from the staple pack 12, the staple cartridge 11 is fitted to a motor driven stapler. Each empty staple sheet pack 12 can be exchanged with a new one by actuating the lock lever 24. <IMAGE>
