Abstract
A reinforcing bar binder capable of certainly identifying the type of a wire reel and automatically adjusting the amount of feeding of the wire wound around the wire reel or the twisting torque on the wire is provided. The reinforcing bar binder feeds a wire while rotating a wire reel mounted in a storing chamber and binds a reinforcing bar. The storing chamber is provided with a first detecting means for detecting the amount of rotation of the wire reel and a second detecting means for detecting the number of second to-be detecting portions on the wire reel during the amount of rotation detected by the first detecting means. The binder main body is provided with controlling means for controlling the amount of feeding of the wire or the twisting torque on the wire based on the basis of the number of the second to-be-detected portions detected by the second detecting means.
