PURPOSE:To accurately control running by correcting the extent of movement to a value corresponding to an actual extent of movement each time when a transport carriage passes a correction point. CONSTITUTION:A controller for the transport carriage consists of a correction point passage confirming sensor 12 which detects a correcting striker 11 arranged at the correction point provided in a prescribed position on a running route, a control part 13, a servo amplifier 14, a running motor 15, a rotation angle detecting resolver 17, etc. The control part 13 is provided with a microcomputer and commands a running speed or the like to the servo amplifier 14. The transport carriage starts running by this command, and the control part 13 receives and counts signals at intervals of a prescribed rotation angle from the running motor 15 to measure the extent of movement. The correcting striker 11 is detected by the confirming sensor 12 to correct the value of the extent of movement in this position. Thus, running is accurately controlled because the extent of movement is corrected at each time of passing the correction point.
