TRACK CONFIRMING VEHICLE, FOREIGN MATTER CONFIRMING SYSTEM BY THIS CONFIRMING VEHICLE, AND PROJECTOR LOADED ON THIS CONFIRMING VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve the precision of foreign matter confirmation and projecting angle and to perform a quick setting by taking the angle formed by the optical axis of a projector and a track when the maximum illuminance part in the illuminating range of the projector is positiceved at a specific distance as a reference angle, and displaying the deflecting angle of the projector from the reference angle. SOLUTION: Since the other end of a laterally driving arm 34 is mounted on a driving shaft 14 mounted on the bottom plate of a support base 13, one end part of the laterally driving arm 34 is laterally rocked to the driving shaft 14, and the front direction of a search light body 1 is laterally changed according to this rocking to laterally deflect the projecting angle. Since the lateral range of the projecting angle is regulated by a limit point detecting sensor, the lateral deflection by a lateral deflecting mechanism is performed within a fixed angle range. Since the vertical and lateral angle deflection of the search light body 1 is performed by use of a servo motor and a stepping motor, the angle can be precisely and quickly changed.
