Abstract
A portable data collection device is disclosed. The device includes an imaging assembly including a two dimensional (2D) photosensor array. The imaging assembly is selectively actuatable with a first trigger for reading a target dataform in the imaging assembly's target area and actuatable with a second trigger for capturing a image of the target object in the target area. The device also includes an illumination assembly including an circuit board assembly supporting illumination and targeting light emitting diodes and a lens array or panel positioned adjacent the circuit board assembly for focusing an even pattern of illumination on the target area and generating a crosshair illumination pattern for aiming the device at the target dataform. Three illumination assembly embodiments are disclosed. In a first embodiment, a lens array is disclosed having a first targeting optics generating a vertical illumination pattern and a second targeting optics generating a horizontal illumination pattern which intersect to form a crosshair illumination pattern. In a second embodiment, a lens array is disclosed having a first targeting optics which generates a first crosshair illumination pattern and a second targeting optics generating a second crosshair illumination pattern, the first and second illumination patterns coinciding at a best focus position of an optic assembly of the imaging assembly. In a third embodiment, a lens array is disclosed having a first targeting optics which generates a half frame and a crosshair illumination pattern and a second targeting optics which generates a complementary half frame and crosshair illumination pattern. At the best focus position, the first and second illumination patterns combine to generate a full frame and single crosshair illumination pattern.
