Compact, omni-directional scan pattern generator and method in a reader for electro-optically reading indicia

摘要

A compact, omni-directional scan pattern generator for generating multiple scan lines used for electro-optically reading bar code symbols includes stationary light-folding mirrors arranged at different elevations on a support, and a rotary mirrored component having a plurality of rotary mirrors for respectively reflecting an incident light beam toward the mirrors at each elevation.
