UNATTENDED CARRYING DEVICE

PURPOSE:To shorten the whole work time by starting a communication related to loading and unloading of goods when an unattended carrying car is being decelerated. CONSTITUTION:A running control part is formed by a running CPU10 of an unattended carrying car, a memory 11, a servo-controlling circuit 12 for controlling a running wheel driving motor 14 basing on a speed command, etc. from the running CPU10, etc. Also, a communication control part for controlling communicating devices 5a, 5b is formed by a communicating CPU16, and a memory 17 for storing a delivery data between said CPU16 and said running CPU10. In this way, the unattended carrying car is brought to a running control, but in this case, when it is detected that the carrying car has been shiftedto a decelerated running in order to stop, whether said communicating devices 5a, 5b can execute a communication or notis decided basing on it, a communication T2 related to loading and unloading of goods of the carrying car is executed within this decelerated running time T1, and a stop time T20 of the carrying car is shortened.
