BACKGROUND
The invention is directed to a portable bar code reader
that can automatically discriminate between a plurality of
different bar code types.
Claim 15 is reproduced below.
15. A portable bar code reader system capable of
reading bar codes of a plurality of bar code types, said
reader system comprising:
(a) a hand-held bar code reader unit;
(b) said hand-held bar code reader unit having a bar
code sensing region, and having a window to be directed
toward a bar code of one of a plurality of bar code types
in said sensing region and providing for transmission of
light between the bar code sensing region and the
interior of said hand-held bar code reader unit;
(c) a photodetector positioned within said hand-held
bar code reader unit for sensing light reflected from a
bar code located within said bar code sensing region, so
as to generate a bar code signal representing the
illuminated bar code;
(d) said hand-held bar code reader unit having a
light path from the window to the photodetector, said
light path oriented to permit said photodetector to sense
light reflected from the bar code along said path while
the reader unit is variably spaced from the bar code and
