Abstract
A bar code reader system for scanning light reflective bar coded labels, including a pivotably mounted spring based housing member having a connecting arm, a light source mounted on the housing member, and a line scan sensor mounted in the housing for sensing reflected light from the bar code label and producing coded signals corresponding thereto. Spring biasing of the housing urges the connecting arm against a plane parallel to the sheet having the bar code label to be read, with the housing pivoting about a pivot axis under spring biased urging, to maintain substantially constant the distance between the bar code label to be read and the line scan sensor.
