Abstract
A rebar tying tool (2; 302; 402) include a feed mechanism (24), which includes a first motor (32; 304) and feeds a wire (W), and a twisting mechanism, which includes a second motor (76; 306) and twists together one or more portions of the wire. A control unit (202; 350) controls the first motor and the second motor and includes a general-purpose I/O port (202c; 350c) and a motor-control-signal output port (202a; 350a). A motor-control-signal-output-destination-switching circuit (204; 310; 406) inputs motor-control signals (UH, VH, WH, UL, VL, WL) from the control unit via the motor-control-signal output port and selectively outputs the inputted motor-control signals to either the first motor or the second motor in response to input of a switching signal (SW).
