Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
69 words
Apparatus for optically reading a document having a transversely positioned data field thereon comprising means supporting the document in arcuate manner, means positioned opposite the data field on the document and movable in the Y direction for reading the extent of the data field, and means responsive to a coil signal and operably associated with the document supporting means for swinging thereof a limited manner in the X direction.
Claim 2
Dependent Claim
69 words
Apparatus for optically reading a document having a transversely positioned data field thereon comprising means supporting the document in arcuate manner, means positioned opposite the data field on the document and movable in the Y direction for reading the extent of the data field, and means responsive to a coil signal and operably associated with the document supporting means for swinging thereof a limited manner in the X direction.
Claim 3
Dependent Claim
28 words
The apparatus of claim 1 wherein said data field comprises a plurality of lines of recorded information extending in the X direction and readable by said reading means.
