Abstract: A refill for staples, which can not be removed from a cartridge unless all sheet-type connected staples in a stapler body are delivered. A refill for staples is installed in a detachable manner in a stapler body, and includes a refill body which holds the sheet-type connected staples, and a pressing member which presses the sheet-type connected staples. A delivery port delivering the sheet-type connected staples and a locking plate provided with a locking section which locks a locked section in the stapler body are formed in the refill body. When the sheet-type connected staples are pressed, the pressing member is engaged with the locking plate not to allow rotation of the locking plate, and, when the sheet-type connected staples are not pressed, the pressing member is disengaged from the locking plate to allow rotation of the locking plate. Thereby, the locking section of the locking plate can be removed from the locked section in the stapler body.

Abstract: A feed roller 32 is disposed in a magazine section 1 such that the feed roller 32 is in press contact with the lower side of a sheet-like staple fed out of a cartridge 13. A rack is formed in the support means of the magazine section 1. The feed roller 32 is operatively coupled with the magazine section 1 through a one-way clutch gear 34 in mesh with the rack 33. Only when the magazine section 1 separates from the clincher section 4, the one-way clutch gear 34 operates to rotate the feed roller 32 in the staple supply direction. The rotation of the one-way clutch gear 34 can be adjusted by a gear ratio of the combination of the one-way clutch gear 34 and the rack 33. Therefore, a sufficient quantity of feeding the sheet-like lowest staple is secured. The feed roller 32 is rotated by utilizing the forward/backward motion of the magazine section 1 with respect to the clincher section. Therefore, provision of any special drive means for rotation is not required.
