Reading techniques
4.4.1 Line scanner (single line)
A line (scan line) scans the label. Due to the opt. 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
limits. These are dependent on the transport speed, the scanning rate of the scanner and the bar code
properties.
Areas of application of the line scanner
The line scanner is used:
• when the bars of the bar code are printed in the conveying direction ('ladder arrangement').
• with bar codes having very short bar lengths.
• when the ladder code is turned out of the vertical position (tilt angle).
• when the reading distance is large.
