Abstract

PURPOSE: To enable to detect lines in some directions with high speed, by detecting either of a plurality of directions predetermined for line and graph direction according to X or Y linked signal line by means of the line detection section.
CONSTITUTION: The line and graph 22 is drawn on the screen 21, illumination is made with the lighting lamp 23, the image 25 decreases the amount of light radiated on the tilt part of the photo electric conversion element 1, and the photo electric conversion element 1 reduces the resistance value to which light is radiated and increases that at the shaded part. Further, the line detection section 10 detects the direction of line and graph present either of a plurality of directions predetermined from the signal on the output line 4 or 5 according to the signal of the X linked signal line 8 or Y linked signal line 9. Thus, the line in some direction can be detected in high speed.
