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.
