Reading techniques
4.5.1
Line scanner (single line)
The scan line scans the label. Due to the optical opening angle, the reading field width is dependent on the
read distance. Through the movement of the object, the entire bar code is automatically transported
through the scan line.
The integrated code reconstruction technology permits twisting of the bar code (tilt angle) within certain lim-
its. These are dependent on the transport speed, the scanning rate of the scanner and the bar code proper-
ties.
Areas of application of the line scanner
• With the bars of the bar code arranged lengthwise with respect to the conveying direction ("ladder ar-
rangement")
• With bar codes having very short bar lengths
• When the ladder code is turned out of the vertical position (tilt angle)
