Title:
METHOD AND DEVICE FOR DETECTING POINTED POSITION OF PICTURE
Document Type and Number:
Japanese Patent JP3447564
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain required position information with a minimum number of light emitting elements with respect to a method and device for detecting a pointed position of the picture.
SOLUTION: Plural scanning light forming means 6 which transmit irradiating light from a light emitting part 1 transmitted to repeating parts 3 in succeeding stages in order by repeating parts 3 provided with light detection parts 2 to form continuous scanning light 5 zigzagging on a display picture 4 are arranged in side edges of the display picture 4 so that continuous scanning light 5 cross on the display picture 4, and the repeating part 3 which reflected light doesn't reach is detected to detect pointed position on the picture.
