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.

[ I claim:] [1.] A portable data collection device comprising:a) a camera assembly, including an array of photosensor elements generating a signal representative of an image of a target area, the image including a dataform positioned in the target area;b) an optics assembly positioned to focus illumination reflected from a generally rectangular target area onto said array of photosensor elements, the optics assembly having a best focus position corresponding to a distance and orientation between the device and the dataform which results in a clear image of the dataform being focused onto the array of photosensor elements;c) image processing and decoder circuitry receiving said signal and generating decoded data representative of the dataform; andd) an illumination assembly directing illumination towards the target area, the illumination assembly including a targeting arrangement for directing an illumination targeting pattern aid in aiming the portable data collection device, the targeting arrangement including first and second targeting light emitting diodes and first and second targeting optics, the first targeting optics comprising a single lens positioned adjacent the first targeting light emitting diode and generating a first illumination targeting pattern and the second targeting optics comprising a single lens positioned adjacent the second targeting light emitting diode and generating a second illumination targeting pattern, the first and second targeting pattern substantially coinciding to form a single illumination targeting pattern when the device is at the best focus position.
