发明名称 METHOD FOR READING DATA PAGES ON A DATA SURFACE
摘要 <p>A method for optically reading data in a substantially planar data field (14) having a plurality of pages arranged in series of rows and columns. Each page is spaced apart from adjacent data pages by alignment-indicating streets (48), which are data-free blank areas. A CCD area array (18) is positioned and spaced apart in generally parallel relation to the data field. The CCD area array is then moved linearly so that the array is opposite a data page to be read. An initial imaging thereafter takes place in order to recognize the streets bordering a data page. Through recognition of the streets, a processor (38) resolves the orientation of the data page relative to the CCD area array. The processor then transmits a command signal to a control circuit (36) for rotational adjustment of the imaging of the data page.</p>
