"auto-discrimination." Claim 15 recites a "bar code signal
processor . . . for determining the type of bar code in said
sensing region and for decoding the information contained in
said bar code signal into a usable form." Claim 25 recites
"circuitry including a microprocessor . . . for automatically

code types . . . and resolving said electrical code signals
into a usable form regardless of which one of said plurality
of code types said electrical code signals represent."
Claim 26 recites "said control circuitry completing the
successive reading of each of a plurality of codes . . .
without requiring any user input or modification to said
portable code reading system between successive actuations."
The Examiner relies only on Knowles and Swartz '798 for
