PROBLEM TO BE SOLVED: To provide a carriage run control device at a low cost, which simplifies the structure of the device and its control by using inexpensive equipment. SOLUTION: A part between two stations of supply/discharge is connected by a out-going/in-coming path line, a current of forward/reverse phase is alternately supplied to a carriage on a respective line from a power feed line 11 along on the respective line, for making the carriage go-out or come in corresponding to respective supply of the phase current. A motor 72 is mounted in the carriage, furthermore, to a out-going/in-coming side end part of the carriage at going/returning time, a detection signal is output by a go/return side stop sensor 55, 56 when respectively the leading carriage approaches, operation of the respective go or return side stop sensor 56 or 55 is detection stopped by a phase detection sensor 71 when a detected phase of the current is forward or reverse, and base on the detection signal of going or returning side stop sensor 55 or 56, motor operation is stopped by an operation stop switch. |
