ABSTRACT:
This invention is a badge and ticket barcode reader which meets the need in the art for a cost effective and reliable barcode reader for naive users. It employs a charge coupled device type scanner in conjunction with a beam splitter, an illumination source which illuminates both sides of the card, a set of mirrors and a guide slot. The set of mirrors reflect light from the two sides of the card to opposite faces of the beam splitter and thus produces an overlaid image of the two sides. The output of the charge coupled device is processed in a known fashion to decipher the barcode. The two sides of the card may be illuminated by a single source via the beam splitter and the set of reflectors or directly via separate sources. The barcode reader may resolve the ambiguity of the two overlaid images either by printing the reverse side of the card black, or via two light sources that are activated alternately in synchronism with the scan of the charge coupled device. The set of reflectors may include three reflectors or two reflectors. This technique is useful for naive users because it can read the badge or ticket no matter which side is inserted, it reads when the badge or ticket is partially or fully inserted and no particular motion other than nearly full insertion is required.
