ABSTRACT:
A focusing lens is manually moved to extend a range of working distances in which a bar code symbol can be electro-optically read. The lens movement enables reading of close-in and far-out symbols. The lens movement can also be used to change operation between a reading mode and a pointing mode in which a visual display is created on a target.
