CONSTITUTION:When a detector 25 detects a deceleration range sheet 27, the driving of a drive motor 12 of a drive wheel 4 is stopped and the unattended truck 1 approaches a station 2 while the direction of the unattended track 1 is corrected to be in parallel with the station 2 by the coasting of the drive wheel 4. When a detector 26 detects a deceleration range sheet 28a, the drive of a drive motor 13 is stopped. When the detectors 25, 26 detect stop sheets 27a, 28b, the drive wheels 4, 5 are braked positively to a stop. |
