Title:
LIGHT RECEIVING DEVICE FOR LIGHT BEAM GUIDED WORK VEHICLE AND TRAVELING CONTROLLER THEREFOR
Document Type and Number:
Japanese Patent JP3044160
Kind Code:
B2
Abstract:
PURPOSE: To enable a sensor for steering control to surely receive the light beam for guidance of a traveling course to be automatically traveled and to realize automatic traveling based on this light receiving information in the case of turning and moving between adjacent traveling courses equipped with the beam light for guidance in a crossing state.
CONSTITUTION: A work vehicle V is provided with a steering control photosensor S1 for receiving the guiding light beam so as to detect the deviation of the guiding light beam projected by light beam projecting means B1 and B2, which are provided on the ground side in a mutually orthogonal state, in the width direction of a car body. Then, a first incidental light limiting means is provided on the front side of light receiving parts S1a and S1b of the photosensor S1 for limiting the guiding light beam to be made incident in the state of being inclined over a prescribed angle (45°, for example), in the breadth wise direction of the car body with a car body forward/backward direction J as a reference so that the light beam can not be made incident on the light receiving parts S1a and S1b.
