First Claim
Patent Images
1. In an optically readable information set reader system, a hand-held bar code reader positionable by hand at varying distances from an information set to be read and operable for reading information sets at distances from said reader within a certain operative range, said reader comprising:
- (a) optically readable information set sensor means for generating an output signal in accordance with an information set image incident thereon;
(b) distance measurement means for automated reading of distances of an information set from the reader;
(c) reading distance adaptation means for automatically adapting the reader to the reading of an information set at varying distances therefrom; and
(d) control means to enable or inhibit readings by said sensor means and for adjustment of said reading distance adaptation means in response to said distance measurement means.
