PURPOSE:To detect easily a control position by providing a transmitting part and a receiving part for forming plural pairs, on an attended car body, and also providing a pattern recognizing passive reflector on the control position. CONSTITUTION:When an unattended car body runs along a leading line 1, and reaches the first control position, a pattern recognizing passive reflector provided on that position couples optically a pair of transmitting part and receiving part of infrared-rays, therefore, a 4-bit transmitter and receiver 35. From the microcomputer 34, a prescribed control signal is sent out to a controlling circuit 19, therefore, an on-time of right and left chopper controlling circuit 20, 21 becomes long, a revolving speed of right and left wheel driving motors 27, 29 increases and the car body runs at a high speed. Subsequently, when it reaches the second control position, a 4-bit signal is inputted to the microcomputer 34 from the transmitter and receiver 35 in the same way, and it turns to the left and runs. Thereafter, in the same way, a running control of the prescribed contents is executed at the third, the fourth,... control positions. |
