General Description
The PI400M-A4 is a CIS module. It is a long contact image sensor, using MOS image
sensor technology for high-speed performance and high sensitivity. The PI400M-A4 is
suitable for scanning A4 size (216 mm) documents with 15.7 dots per millimeter
resolution. Applications include document scanning, mark readers, gaming and office
automation equipment.
Functional Description
The PI400M-A4 imaging array consists of 27 sensors that are cascaded to provide 3456
photo-detectors with their associated multiplex switches, and a digital shift register that
controls its sequential readout. Mounted in the module is one-to-one graded indexed
micro lens array that focuses the scanned documents to image onto its sensing plane.
