Abstract
PURPOSE: To attain accurate and fast reading by making it possible to scan a bar code in any direction, by using a video turntable type prism.
CONSTITUTION: This reader is equipped with light source 2 illuminating scanning window 1 where commodity 3 is placed, optical system 4 between scanning window 1 and pickup unit 5 for the image formation of bar codes printed on a tag card onto unit 5, and video turntable type prism 8 which rotates practically the formed image on unit 5. Then, the arrangement direction of bar codes is made to agree with the scanning direction of unit 5 once while prism 8 rotates once. Therefore, bar codes can be read through accurate acanning regardless of the direction of bar codes
