ABSTRACT:
An electric stapler comprises a feed mechanism for sequentially feeding a staple from a magazine loaded with a plurality of staples to a striking portion, a striking mechanism for striking the staple fed to the striking portion toward sheets of paper by a driver plate, a clincher mechanism for bending a staple leg struck by the driver plate and penetrated through the sheets of paper along a backside of the sheets of paper, a drive mechanism for driving the feed mechanism, the striking mechanism and the clincher mechanism by the electric motor, a detection mechanism placed in contact with a rotary member provided in the drive mechanism and for detecting a consumed amount of the drive mechanism, and an indicator mechanism for indicating a consumed amount detected by the detection mechanism, thus making it possible to detect an endurance life of the electric stapler.
