A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.

In an apparatus for scanning an image line by line to produce data representative of the image scanned, the improvement comprising: a movable carriage; at least two arrays, each of said arrays comprising a plurality of discrete photosensitive elements arranged in succession along the linear axis of said array, the length of the viewing area of each array being less than the width of the image scanned; means supporting said arrays on said carriage for scanning said image with the linear axis of said arrays extending in a direction substantially perpendicular to the direction of scanning movement of said carriage; said arrays being supported so that said array viewing areas overlap whereby to provide a composite array viewing area having a length at least equal to the width of the image scanned; means for actuating said carriage and said arrays to move said carriage and scan said image; and readout means for reading out data from said arrays in succession one line at a time, said readout means including crossover means for crossing over from one array to the next succeeding array within the overlapping portion of said array viewing areas on a random basis, said crossover means being adapted to change the crossover point between said arrays with each succeeding line.
