PURPOSE:To change a direction by rotating one wheel between a lateral pair of wheels of a drive runner normally while rotating the other wheel reversely to turn the drive runner when the drive runner traveling on a ceiling rail automatically while hanging a panel passes a corner part. CONSTITUTION:When a partition panel 31 in a storage 74 travels aslant and a drive runner 1a approaches a turning area 67c, a proximity switch 66b detects this and stops the runners 1a, 1b. The wheels 25a, 25b of the runner 1a are mutually rotated normally and reversely to turn the runner 1a for direction change, and then the wheels 25a, 25b are placed in the free state. The drive runner 1b is then started to travel and approach turning area 67a, and the runner 1a is pushed out to an auxiliary travel path 72. The runner 1b is detected to be in the area 67a by the switch 66b, and the wheels 25a, 25b are stopped. The wheels 25a, 25b are then rotated mutually in the normal and reverse state to change the direction of the runner 1b. The runners 1a, 1b are further driven to travel at high speed on the auxiliary travel path 72. The panel can be thereby moved in multiple directions. |
