Abstract:
1. An arrangement for electro-optically reading indicia with visual feedback to a user, comprising: a) a solid-state image sensor operative for capturing an image of the indicia with a detector having an adjustable exposure time and for generating an electrical signal indicative of the indicia, during reading of the indicia; b) a light source for forming a visible light line across the indicia during reading of the indicia by the solid-state sensor; and c) means for directing the visible light line to and away from the indicia during reading of the indicia by the solid-state sensor to generate a flickering line that simulates for the user a fluctuating scan line generated by a moving beam electro-optical reader, the directing means being operative for adjusting the exposure time and for turning the visible light line off after the exposure time has been adjusted.
