Abstract

Embodiments of the present invention are directed to barcode readers implementing multiple circuit boards for housing various electronic components. In one embodiment, the invention is a handheld barcode reader comprising: a handle portion; a head portion positioned on top of the handle portion; a window positioned within the head portion; a first circuit board at least partially extending By means of the handle portion, a first circuit board defines a first plane, the first circuit board includes a decoding assembly; and a second circuit board is positioned behind the first plane relative to the window, the second circuit board includes an imaging assembly with an imaging sensor, The imaging sensor is operable to capture image data over a field of view (FOV) extending through the first plane and the window.

Description

technical field [0001] This application relates generally to barcode readers. Background technique [0002] The operating range of imaging-based barcode readers is limited by several factors, including image sensor resolution, the depth of focus of the optical system, and noise generated within the image sensor. In addition to these factors, image sensor resolution can be a limitation that is often not easily overcome. This is especially prevalent when reading high density barcodes (barcodes with relatively small bars or spaces). The problem stems from the fact that the sensor's field of view expands with distance from the reader, spreading pixels over larger and larger areas, reducing the number of pixels available to resolve small features such as narrow elements in high-density barcodes. ) of pixels. In the end, small elements cannot be parsed adequately, and the barcode can no longer be decoded. [0003] This situation can be partially resolved by using an imaging se...
