Abstract

A sensor with functions of line-following and side-following having two-row light emitting source design used for deviation rectification is disclosed. Mainly, two-row LEDs operate in coordination with a diamond-shape masking device to be the light emitting source, and each row of the two-row LEDs has several LEDs spaced with equal distance. The several LEDs emit light with intensity from low to high in sequence. The light emitting from the two-row LEDs incident on the original material paper is reflected to obtain the analog output to monitor degree of deviation from the original setting point. In order to make amplitude of the analog signal in proportion to the deviation position, a masking device with diamond-shape holes is placed in front of the two-row LEDs so that every light emitted from the light source would have a diamond-shape. The two-row LEDs provide a straight light source with light emitting intensity linearly changing from left to right.
