Claim Text:
1. A reinforcing bar binding machine comprising: a binding wire feeding mechanism that feeds a binding wire which is wound around a reel to a binding wire guiding nose and forms a binding wire loop around a reinforcing bar; a binding wire twisting mechanism that twists the binding wire loop formed around the reinforcing bar, by grasping and rotating the binding wire loop; a power supply voltage detecting device; a device for comparing a detected voltage of the power supply with a predetermined minimum operation voltage required to operate the reinforcing bar binding machine; and a control device that drives a motor in a reverse direction, when the detected voltage of the power supply has dropped below the predetermined operation voltage, thereby to return the binding wire twisting mechanism to an initial position, wherein the detection of the power supply voltage for controlling the return of the binding wire twisting mechanism to the initial position is carried out only during a reinforcing bar binding step.
