PURPOSE:To attain automatic carrying with use of a carrier truck without using a guide rail by controlling the carrier truck in accordance with the current position of the carrier truck, a peripheral condition and a command signal. CONSTITUTION:When an indicator pointer 2 detects a beam projected from a beam projector 17 mounted on the carrier truck 3, a position specifying signal indicating the arrangement position of the pointer 2 is originated from an originating device included in the pointer 2. A position detecting means 22 detects the current position of the carrier truck 3 by obtaining the projecting direction of the beam projected from the beam projector 17 and detected by plural pointers 2 and the position specifying signals originated from the plural pointers 2 in accordance with the beam. The moving device control means 22 controls a moving device 18 in accordance with the current position of the carrier truck 3 detected by the position detecting means 22, the peripheral state of the carrier truck 3 detected by state detecting devices 20, 21 and a command signal transmitted from a command device 1 to move the carrier truck 3. Consequently, carrier based upon the carrier truck can be attained without using a guide line. |
