PURPOSE:To effectively control running of an unattended car without providing a control line separately, by providing an induction line for driving the unattended car, and transmitting an address indicating number of the unattended car through this line. CONSTITUTION:To an inspection spot provided on a runnng route, for instance, S1-S7, each different address is given. In this state, whenever an unattended car 1 reaches each inspection spot S1-S7, an address of its reached point is indicated on the unattended car 1. Also, in accordance with a detecting signal of unattended car detectors 51-57 provided on each inspection sopt S1-S7, a code converting circuit 8 converts the address of the detection spot where the unattended car 1 has been detected, to a code corresponding to its address. Subsequently, the converted coder is sent out to an induction line 2 through a gate circuit 22 and a mixing circuit 23 from a CPU10. |
