Patent ID: 6971579

Claim:
An arrangement for generating a dynamic, omni-directional scan pattern in a reader for electro-optically reading indicia, comprising: a) a housing having a window; b) a rotary mirrored component mounted in the housing for rotation about an axis; c) a plurality of stationary, folding mirrors mounted in the housing and generally arranged about the axis; d) a light source mounted in the housing and operative for generating and directing a light beam toward the rotary component for reflection therefrom to the stationary mirrors for reflection therefrom through the window to the indicia to be read; e) a motor in the housing for rotating the rotary component to sweep the light beam across the stationary mirrors to form an omni-directional scan pattern comprising a plurality of scan lines at the window; f) an oscillating mirror mounted for oscillation in the housing between the light source and the rotary component; and g) a drive for oscillating the oscillating mirror to move the scan pattern relative to the window.
