)
In the following conditions, readable up to
β
= +/-50°.

= 0°, tilt angle
γ
= 360°, curvature R =

Reading performance for bar codes on a highly gloss surface such as glossy paper or a card case
may be impaired because reflected illumination LED light or room illumination light enters the
reading window.
If reflected illumination LED light is the culprit, reading performance can be improved by providing
an angle of about 15° in the skew direction or turning off the illumination LED light.
