Title:
LEADING LINE DETECTING DEVICE FOR UNATTENDED LEADING VEHICLE
Document Type and Number:
Japanese Patent JPS5960513
Kind Code:
A
Abstract:
PURPOSE:To detect information from a leading line with high accuracy by rotating plural lenses placed in front of a photodetector, and detecting a position of the leading line as plural signals. CONSTITUTION:A motor 1 rotates a rotary shaft 2. Two lenses 4, 4' are fitted to a lens fitting piece fitted to the tip of the rotary shaft 2. Light from a leading line 10 is projected to a positon of two places on a photodetector 5 through the rotating lenses 4, 4'. The photodetector 5 is like a ring and is divided into three or four equal parts. In what place a position of the leading line exists against the center of a rotation of the lenses 4, 4' can be detected simultaneously as two electric signals from the photodetector 5. Accordingly, simultaneously with position information of the leading line 10, information from a command pattern provided on the leading line 10 can be detected.
