Abstract

PURPOSE:To prevent trucks from colliding with each other when a plural truck is kept running concurrently on the same track by equipping each truck with light receiver, projector and reflecting mirror. CONSTITUTION:An anticollision mechanism of a truck 16 comprises a projector 21, a light receiver 22 and a reflecting mirror 23. The projector 21 irradiates the reflecting mirror 23 on the front or the back of the opposite truck 16. Then the light radiated as above is reflected by the reflecting mirror 23 and thus returns to the light receiver 22. The light receiver 22 is then induced only by the light coming in a specified wavelength realm, and the light emitted from the projector 21 is limited to that of coming in the specified wavelength realm. Therefore, the light receiver 22 is actuated for detection upon receipt of the light of more than a constant strength and issues a signal to stop the truck 16. The two trucks coming near to each other receive the light emitted by themselves on their light receiver by way of the opposite reflecting mirror, thus stopping without collision.
