Abstract

PURPOSE: To obtain a stop precision and safety on operations with a simple constitution, by cutting off a part of the inductive band and by detecting this cut part to generate a speed reduction command.
CONSTITUTION: When unattended cart 18 goes from point A to point B (the cut position), where reflection bands 1A and 1B are not provided, while being driven in a high speed, the light radiated from lamp 6 is not reflected sufficiently onto detecting elements 4aW4j of reflection light detecting unit 3, and the detection signal is broken temporarily, and the speed reduction command is issued from running control circuit 8 to motor driving circuit 10 by the fall of the detection signal during passage through cut distance l1 from point A to point B where said reflection bands are not provided. As a result, the speed of cart 18 is reduced, and cart 18 can be caused to run in a low speed in distance l2 from point B to point C where stop point 17 is provided, and cart 18 can be stopped from the speed reduction state at stop point 17. Therefore, a high stop precision can be obtained.
