Abstract
In an exemplary embodiment, a hand-held bar code reader has an elongated relatively narrow hand grip portion and an enlarged reader head portion with an extended window of greater width that the hand grip portion. Preferably the lens system provides a depth of field for such bar code patterns of at least ten millimeters, so that a bar code pattern of marked curvature can be read in its entirety by means of an instant reading operation. The preferred embodiment provides a single unitary circuit board configuration with a rigid lens mounting arrangement which furthers the achievement of a precise and reliable optical system.
