PURPOSE: To calculate the position of a transfer car from the reflection time of noncontact light wave, to detect accurately the position of the transfer car without causing environmental error, and to carry out safely automatic operation, by using a projector and receptor part laid on the transfer car and a corner cube group arranged at the end parts of a travel path.
CONSTITUTION: In facilities of coke oven having the transfer car 2 such as charging car, guide car, pushing car, etc., the projector and receptor 4 for laser beam is set on the transfer car 2, and the plural corner cube groups 3 to subject the laser beam to total reflection at the end part of the travel part 1 of the transfer car 2, respectively. The transfer car 2 is preferably equipped with the device 5 ?for measuring the position of the transfer car 2 from the receptor output of the projector and receptor 4, and with the control device 6 to input the output of the device to itself and to carry out drive control of the transfer car 2. The position of the transfer car 2 is calculated by projecting the laser beam 7 from the projecting part of the projector and receptor 4 to the corner cube groups 3, to carry out drive control.
