Abstract: PURPOSE:To realize accurate positioning/stopping of a carrier on a predetermined position of a track only through brake force control. CONSTITUTION:Moving direction and position of a carrier 1 entering into a stop area of a track are detected by a first detecting means (sensor 5) through a scale 2 mounted on the carrier and brake force required for stopping at a predetermined position is calculated by means of a controller and then a control means is controlled based on the calculation results.
