Abstract
Abstract A compact code format has marking elements of two distinctive lengths which lie across a set of parallel equal height code zones. The longer of the two lengths exceeds the length of the shorter by twice the height of a code zone, thereby providing a substantial uniformity of separation between all members of the code set.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
A record for machine reading, comprising a record base having on a surface thereof a background region of a first optical characteristic and a plurality of marking elements of a second, contrasting optical characteristic, said marking elements being individually arranged in successive spaces which are disposed side-by-side in a line, and wherein the improvement comprises: said elements being selected from a plurality of different predetermined lengths in their dimension transverse to said line, and being positioned in different ones of a predetermined set of equal height zones extending parallel to said line, each of said different lengths differing from the length nearest thereto by at least the height of two of said zones, whereby each element uniquely identifies by its length and location, a character of a predetermined set of characters.
Claim 2
Dependent Claim
131 words
A record for machine reading, comprising a record base having on a surface thereof a background region of a first optical characteristic and a plurality of marking elements of a second, contrasting optical characteristic, said marking elements being individually arranged in successive spaces which are disposed side-by-side in a line, and wherein the improvement comprises: said elements being selected from a plurality of different predetermined lengths in their dimension transverse to said line, and being positioned in different ones of a predetermined set of equal height zones extending parallel to said line, each of said different lengths differing from the length nearest thereto by at least the height of two of said zones, whereby each element uniquely identifies by its length and location, a character of a predetermined set of characters.
Claim 3
Dependent Claim
39 words
A record as defined in claim 1 wherein said plurality of marking elements is preceded by a reference mark which extends parallel to said elements and which indicates by its end points, the extremities of said set of zones.
Claim 4
Dependent Claim
15 words
A record as defined in claim 1 wherein said record base comprises a bank check.
Claim 5
Dependent Claim
27 words
A record as defined in claim 1 wherein the length of the shortest of said elements is substantially equal to the height of one of said zones.
Claim 6
Dependent Claim
62 words
A record as defined in claim 4 wherein said predetermined set of characters comprises the digits 0 through 9, wherein there are six zones in said predetermined set of zones, and wherein only two lengths are employed to encode said set of characters, the longer of the two lengths being substantially equal to three times the height of one of said zones.
Claim 7
Dependent Claim
30 words
A record as defined in claim 1 wherein each of said elements has a dimension parallel to said line that is less than the space in which the element lies.
Claim 8
Dependent Claim
39 words
A record as defined in claim 5 wherein said plurality of marking elements is preceded by a reference mark which extends parallel to said elements and which indicates by its end points, the extremities of said set of zones.
Claim 9
Dependent Claim
15 words
A record as defined in claim 7 wherein said record base comprises a bank check.
Claim 10
Dependent Claim
44 words
Apparatus for reading a record as defined in claim 8 comprising transport means for moving the record base in the direction substantially parallel to said zones, and reading means positioned adjacent said transport means for detecting said elements during operation of said transport means.
Claim 11
Dependent Claim
44 words
Apparatus for reading a record as defined in claim 1 comprising transport means for moving the record base in the direction substantially parallel to said zones, and reading means positioned adjacent said transport means for detecting said elements during operation of said transport means.
