Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
An array for use in apparatus of the type employing plural arrays disposed so that a finite portion of one array overlaps a finite portion of an adjoining array to provide a composite array, comprising a. an array substrate, said substrate being generally rectangular in shape; b. a multiplicity of operating elements on said substrate, said operating elements being disposed in succession longitudinally of said substrate; c. the center-to-center distances between said operating elements in said finite portion of said array being different than the center-to-center distances between the remainder of said operating elements of said array whereby to provide a vernier-like spacing between said operating elements in the finite portion of said array facilitating alignment of at least one operating element in said array with an operating element in the adjoining array.
Claim 2
