Abstract
An optical scanner for reading two-dimensional bar code labels. A rotating reflector directs a laser beam towards a plurality of pattern mirrors during a first mode of operation to produce a plurality of different scan lines forming a multi-line scan pattern for collecting light from an article having a one-dimensional bar code label, and directs the laser beam towards one of the pattern mirrors during a second mode of operation to produce a single scan line for collecting light from an article having a two-dimensional bar code label. A single tilted mirror assembly, having a motor for rotating a drive shaft and a mirror mounted at an angle to the drive shaft, reflects the plurality of different scan lines towards the article having the one-dimensional bar code label during the first mode of operation, and reflects the one scan line from the scan module towards the article having the two-dimensional bar code label during the second mode of operation.
