STAPLER AND STAPLE CARTRIDGE

摘要

A retainer spring (208) is provided in a casing, and a new staple strip material (300) can be charged without the need of disassembling a cartridge casing (210) even if a stopper portion (303) is provided on a tail end of the staple strip material (300). A closing cover (B) is defined by a portion which extends rearward from any position between a tip end (202a) of the casing and a stopper engagement (209) for the tail end (303) of the staple strip material. The closing cover (B) is opened to release portions of the retainer spring (208) and the stopper engagement (209), thus enabling removing of the remaining staple strip material (300) and recharging of the new staple strip material (300).
