PURPOSE:To omit the installation of a positioning device on the surface of a course and to obtain a positioning device having the inexpensive cost of construction, by providing a display device on the side face of an equipment at the remote side to show the standard of the stop position and shifting the bed of an unmanned carrier after recognizing said display device. CONSTITUTION:The cross-shaped marks 2 and 2 are put on the side face 1a of a machine tool 1 at two points in the horizontal direction. When a carrier 5 stops at the side face 1a of the tool 1, the contacts 20 and 20 of the carrier 5 are protruded until they touch the face 1a of the tool 1. Then an angle of the bed 6 is obtained against the face 1a from the difference of amount of protrusion between both contacts 20. A motor 9 is controlled to set the tool 1 in parallel with the carrier 5. While the distance between the face 1a and the carrier 5 for decision of the amount of protrusion of a fork 6a. both marks 2 are detected by TV cameras 21 and 21. Then a front-back shift if detected is corrected with operation of a hydraulic cylinder 18; while a hydraulic cylinder 15 is operated for correction of the variation of height and the front-back slope respectively.
