Reinforcing bar binding machine, wire reel, wire, and method of determining kind of wire
摘要：
A wire reel containing portion 3 of a reinforcing bar binding machine 1 is provided with a rotation detecting lever 8 and a photosensor 7. When a wire reel is rotated in starting to bind a wire, rotation thereof is detected by the rotation detecting lever switched ON/OFF by a projected portion formed at a side face of the wire reel, the photosensor detects a reflection mark of the wire reel to determine a kind of the wire from a number of the marks, and a twist torque or the like is controlled. Wire information is detected not in an initializing operation (in setting wire) of rotating the wire reel at low speed but in a binding operation of rotating at high speed and therefore, an amount of swinging the rotation detecting lever is large and wire information can firmly be detected.
摘要（中）：

钢筋捆扎机1的钢丝卷轴容纳部分3设置有旋转检测杆8和光电传感器7.当钢丝卷筒开始旋转以绑定钢丝时，其转动由旋转检测杆开启而被检测 通过形成在线卷盘的侧面的突出部分，光电传感器检测出卷线筒的反射标记，从多个标记确定线的种类，并且控制扭转扭矩等。 检测不到在低速旋转钢丝卷筒的高速运转（设定线）的电线信息，而是在高速旋转的装订操作中，因此，旋转检测杆的摆动量大，线信息可以牢固 被检测。
