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.
Claims5
A bar code reader system for scanning a light reflective bar coded label located on the surface of a sheet stacked in a magazine, and for providing coded signals corresponding to the coded label, comprising:
- a pivotably mounted housing member having a scanning surface axis;
- a source of light connected to said housing member for directing a focused light beam on said label;
- light sensor means mounted in said housing member for receiving light reflected from the bar-coded label located on the surface of the sheet and for providing coded signals corresponding thereto;
- and
- means associated with said housing member for maintaining substantially constant the distance between said light source and said bar-coded label located on the sheet.
