PURPOSE:To catch a light beam surely by forming the light beam image of a screen that receives the light beam on the light receiving section of a sensor by a lens. CONSTITUTION:Steering and running wheels 2 and follower wheels 3 are provided in a body frame 1 to constitute an unmanned car that can run forward and backward. A laser light generating device 4 and a mechanism 5 that projects the ray of light along the running line in the state of vertical slitlike wide ray of light are provided on both ends of the forward and backward running line on the ground side. At this time, a sensor 6 that detects lateral displacement of the body to the light B, a transmitter and receiver of destination data etc. and a controlling arithmetic unit are provided on the unmanned car side. At the same time, a screen 11 and a convex lens 12 for image forming the light image on the screen 11 on the light receiving section of the sensor 6 are provided. Thus, the image of the light image is formed on the light receiving section of the sensor in a reduced state. Small-sized CCD etc. can be used for the sensor. |
