<p>A reinforcing bar binding machine is provided with a device for detecting a power supply voltage during a binding wire twisting step subjected to the heaviest load and comparing the power supply voltage with a predetermined CPU operation voltage, and a control device for driving a motor in a reverse direction when the voltage has dropped below the predetermined CPU operation voltage. The power supply voltage during operation is monitored, and twisting operation is suspended before the voltage drops below the CPU operation voltage, whereby the binding wire twisting mechanism is returned to the initial position. Therefore, it is possible to prevent the binding wire twisting mechanism from being stopped while grasping the binding wire, when the CPU stops.</p> |
