Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
132 words
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.
Claim 2
Dependent Claim
132 words
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.
Claim 3
Dependent Claim
28 words
An optically readable information set reader system as recited in claim 1, wherein said distance adaptation means comprises an adjustable lens system responsive to said distance measurement means.
Claim 4
Dependent Claim
22 words
An optically readable information set reader system as recited in claim 1, further comprising marker means to facilitate aiming of said system.
Claim 5
Dependent Claim
33 words
An optically readable information set reader system as recited in claim 1, further comprising a flashable illuminator means for producing a reflected image of the information set for reading by said sensor means.
Claim 6
Dependent Claim
18 words
An optically readable information set reader system as recited in claim 4, further comprising a flash interrupter means.
