Title: Bar code reader
Inventor: UMETSU MITSUO
IPC: G06K7/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To make stably judgeable the black/white bars of a bar code even if the sensitivity is deteriorated or a meandering of paper exists. SOLUTION: A Schottky diode D2 is connected in parallel to a resistor R4 in a voltage dividing circuit 3'. The forward voltage Vf of the Schottky diode D2 is always constant.
