The PI3011A is a 300 DPI solid-state line imaging array, also a product of Peripheral Imaging Corporation. This imaging dev ice is fabricated using MOS imaging sensor technology for high-speed performance and hig h sensitivity. The PI321MC-A6 is suitable for scanning A6 size (104 mm) documen ts with 11.8 dots per millimeter resolution. Applications include ticket, check an d card scanners, variety of mark readers, and other automation equipment. Functional Description The PI321MC-A6 imaging array consists of 13 sensors that are cascaded to provide 1248 photo-detectors with their associated multiplex switches, an d a digital shift register that controls its sequential readout.
