To provide an unmanned carrier which can stop at a target position with high accuracy and also in which a control mechanism needs only a small quantity of data for instructing a motor.

A position information means 27 is arranged at a prescribed position 7, a carrier 21 is provided with a sensor 29 for detecting the position information means 27 and also with an encoder 30. The encoder 30 is utilized to detect the speed of the carrier 21 to control the speed of the carrier until the sensor 29 detects the position information means 27 arranged in front of the prescribed position 7. When the sensor 29 detects the position information means 27 at the prescribed position 7, the encoder 30 is utilized to detect the position of the carrier 21 to control the speed of the carrier 21 and to perform deceleration/stopping control.
