The present invention relates to a scanning device with a positioning senor and a processing method to obtain images, comprising a casing, linear contact image sensor (CIS), further comprising a system processor Pfor controlling the work of said CIS by timing signal, the optical coordinate sensors and the displacement processor Pand Pfor estimating the coordinate increment () and the coordinate increment () of the real-time displacement, an A/D circuit and data buffer; said system processor Ppackets original scanning data with positioning information (), and then transfers to the upper machine. An image processing module in the upper machine de-packets said original scanning date (); Converts out the coordinate of the terminal pixel of said linear contact image sensor (CIS), and configures the image line in the object image configuring area; and calculates and rectifies the relative offset of the positioning coordinate of the two scanning bands making using of the statistical characteristic of part of pixel data in the overlapped area of the two scanning bands.

An insert-type barcode reader has a body support with an insertion slot for receiving a card with barcode. A circuit board and a CIS component module electrically connected to the circuit board with each mounted to the body support to scan and process signals. A roller is mounted to the body support for movement relative to the CIS component module to allow the card to be properly guided into the insertion slot and tightly pressed onto the CIS component for accurate scanning of the barcode on the card. Two photoelectric sensors mounted to the body support are electrically connected to the circuit board for sensing the card entering and leaving the insertion slot to control starting, running and stopping of the scanning function of the CIS component module.
