Abstract: An antenna of an RF tag reader and a photo sensor for detecting a rotational position of a wire reel are provided in a wire reel receiving portion of a reinforcing bar binding machine. The photo sensor detects a mark on the wire reel, and when an RF tag mounted on a side surface of the wire reel is brought into opposed relation to the antenna of the RF tag reader, a control portion decelerates or stops the wire reel, and an RF tag recognition operation by the RF tag reader is executed, thereby identifying a wire kind. When the RF tag is opposed to the antenna of the RF tag reader, the wire reel is decelerated or stopped, and in this condition the transmitting and receiving operations are executed, and therefore the stable communication can be executed.

Abstract: A front end of a loop of a wire fed out to a nose (6) by a binding wire feeding mechanism (1) is pinched by a clamp plate (28) of a binding wire clamping apparatus (25) and the wire is pulled back by driving to rotate reversely a feeding motor (13) of the binding wire feeding mechanism (1). When the wire is brought into close contact with a reinforcing bar (S) and a load of the feeding motor is increased to thereby increase a drive current by a constant amount, a control apparatus stops the feeding motor. Thereafter, the binding wire clamping apparatus (25) is rotated to twist the binding wire to bind the reinforcing bar. Since the wire is pulled back and a length of the wire is automatically adjusted in accordance with a diameter of the reinforcing bar, a state of finishing to bind the reinforcing bar is made to be uniform and also an amount of consuming the wire is reduced.
