Abstract:
1. An arrangement for scanning indicia associated with objects passing in an advancement direction across a single horizontal window of a point-of-transaction workstation at which the indicia are to be electro-optically read, the arrangement comprising: a) a rotary mirrored component rotatable about an axis, the rotary component having a plurality of planar tilted mirrors tilted at different angles of inclination relative to the axis; b) a plurality of stationary, folding mirrors arranged generally about the axis; c) a light source for generating a light beam; d) an oscillator for oscillating the light beam, and for directing the oscillating light beam to the rotary component for reflection from the tilted mirrors to the stationary mirrors for reflection therefrom through the window to multiple surfaces of each object; e) a drive for rotating the rotary component to sweep the oscillating light beam across the stationary mirrors and form a scan pattern of scan lines at and past the window and onto the multiple surfaces of each object; and f) at least one of the stationary mirrors being located behind the rotary component, as considered downstream of the advancement direction, for reflecting at least one of the scan lines at a trailing surface of each object.
