Abstract
PURPOSE: To enable to read the bar code informarion correctly and quickly at all times by the detected body place on the scanning window, by detecting the reflection light from the detected body and drawing the scanning locus greater in the scanning density on the scanning window.
CONSTITUTION: The light from the laser 10 is deflected with the deflection reflective mirror 12 in which the angle is changed on the voltage change fed after the optical lens 11, and it is fed to the rotary reflection mirror 4, and the scanning window 5 is sequentially scanned via the solidstate reflection group 5 after reflection. Further, the reflection light from the detection body place on the scanning window 6 is detected at the photo detector 13 and the information of the detected body is optically read in. In this case, the reflection mirror 12 is in deflection drive control on the output signal of the detector 13, and when the reflection light from the detected body is detected by the detector 13, the scanning locus greater in scanning density is drawn on the scanning window 6. Thus, even if the detected body placed on the scenning window 6 is positioned in any direction or position, the bar code information can correctly and quickly be read in at all times.
