OPTICAL SCANNER WITH TOP DOWN READER

摘要

A data reading system (100, 300, 400, 800) including one or more imagers (210, 215), the data reading system having a lower main housing structure (105, 410) with a horizontal surface (130/132, 320, 412), across which items to be read are passed, and an upper reader module, such as pole-mounted top down reader (TDR) (175, 375, 500, 850) including (a) a bottom imager (181/195, 570) configured to provide a top down viewing angle from above the horizontal surface of the item (20) in a read region and/or (b) a top imager (566) configured to provide an upward or sideward viewing angle out from the TDR. In one configuration, a pole-mounted TDR may include a one-piece post housing section (510) mounted to the main housing structure (105, 410) and extending therefrom and containing imaging electronics and optics of the upper reader module.
