laser scanner
An optical bar code reading device that uses a low energy laser light beam to
examine a spatial pattern, one part after another. It then generates analog or

recognition. The laser scanner converts bar code symbols to electrical signals
for input to a bar code decoder for processing and subsequent output through
a data communications interface.

trigger and stay on until you release the trigger. Contrast with edge triggering.
