Luster scan
Luster scan is a system to scan plural laser beams toward the bar code height direction
as shown in the figure.
Number of conformance (number of verification)
Decode several times and verify if the results conform. When it conforms for the
number of the conformance set beforehand, it is output to RS-232C interface. Number
of conformance should be at least twice (number of verification is once) to increase
reliability.
Narrow bar (slim bar)
The narrower bar in the bar code consists with horizontal bars is called a "narrow bar".
The narrow bar should be wider than the minimum resolution which the bar code
reader can resolve, to read it.
The thicker bar than the narrow bar is called a wide bar (thick bar).
Parity
This is a means to prevent communication error.
"Parity check" is a data check system which adds 1 bit to data and to have the total bit
of "1" either in even number or odd number. The added 1 bit at this time is called "parity
bit".
