Abstract
A reinforcement binding machine (1), comprising a wire reel storage part (3) having a rotation detection lever (8) and a photo sensor (7). When a wire reel is rotated in starting binding, the rotation detection lever is turned on and off by a projected part formed on the side face of the wire reel to detect the rotation, and the photo sensor detects a reflection mark on the wire reel to discriminate the type of the wire by a mark number so as to control torsional torque, etc. Since wire information is detected in binding operation when the wire reel is rotated at a high speed not in initialization operation (in setting the wire) when the wire reel is rotated at a low speed, the swing amount of the rotation detection lever is large and, accordingly, the wire information can be securely detected.
