ABSTRACT:
A bar code scanning apparatus having a laser beam source 1, a scanner 7 for scanning a laser beam 2 emitted from the laser beam source 1 in an scan angle range of -.theta..sub.1 to +(.theta..sub.1 +.theta..sub.2) relative to the laser beam, a window 5 substantially perpendicular to a counter surface and which transmits therethrough scan beams scanned by the scanner 7 to the exterior of the reader, a plurality of first fixed mirrors 8A, 8B and 8C for dividing scan beams, which are generated within the scan angle range of -.theta..sub.1 to +.theta..sub.1, into a plurality of scanning lines generally symmetric with respect to the laser beam and emitting the scanning lines from the window 5, and a plurality of second fixed mirrors 26A, 26B1 and 26B2 for dividing scan beams which are generated within the scan angle range of +.theta..sub.1 to +.theta..sub.2 and emitting the resulting scanning lines from the window 5 toward a checkout counter. Thus, it is possible to permit reading of a bar code by merely moving a commodity taken out from an incoming-side basket into an outgoing-side basket without changing the manner of holding the commodity and without changing the direction of the commodity.
