Module or arrangement for, and method of, reading a target by image capture with an imaging reader having offset imaging and aiming systems

摘要

An imaging sensor 10 of an imaging reader (30) senses return light from a target to be read by image capture along an imaging axis over a field of view 20 that extends along mutually orthogonal, horizontal and vertical axes. Two aiming light assemblies 42,44,46 are offset from the sensor and are spaced apart along the horizontal axis at opposite sides of the sensor, and direct two aiming light lines 50, each having a predetermined brightness, at the target. The aiming lines are collinear along the horizontal axis and have inner linear end regions 50A that overlap on the target to form a bright, linear, aiming mark 60 having a brightness greater than the predetermined brightness to visually indicate a center zone of the field of view. The aiming lines may also have outer linear end regions 50B that visually indicate approximate end limits of the field of view, over a range of working distances.
