Abstract
A horizontal scanning device capable of scanning a bar code label on an underside or on a standing side wall of an article is revealed. The device is made of a source of laser light; a rotatably drivable polygonal mirror with mirror surfaces for distributing in scan lines the laser light transmitted by the laser source; a number of fixedly disposed mirrors for reflecting through a window the laser light beam distributed by the polygonal mirror, wherein the polygonal mirror has at least one mirror surface in co-action with a fixedly disposed mirror and at least one laser light beam is directed through the window at the article, which line extends for at least a moment substantially vertically to that window and the projection of which onto the article moves substantially in the plane perpendicular to that window and through that vertical line; and a detector for receiving light scattered by the code.
