Abstract
Abstract HIGH DENSITY MATRIX CODE Abstract of the Disclosure A machine-readable matrix-type code has either repeated or non-repeated dot patterns in one direction representing digital characters which are read by a sensor moved in a direction which is gener-ally normal to the patterns. The patterns of the code may be formed in a manner wherein the sensor views a portion of repeated patterns, or the code may be of lesser magnitude wherein the entire non-repeat-ed pattern area is covered by the field of view of the sensor.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
80 words
A machine readable code comprising a plurality of dots arranged in rows and columns in X and Y directions to form a pattern repre-senting characters in the Y direction and conveying information by presence or absence of a dot at a specific location, said pattern of dots being repeated in the Y direction for reading in a manner wherein the field of view of reading the pattern in the Y direction is less than the repeated pattern for a character.
Claim 2
Dependent Claim
80 words
A machine readable code comprising a plurality of dots arranged in rows and columns in X and Y directions to form a pattern repre-senting characters in the Y direction and conveying information by presence or absence of a dot at a specific location, said pattern of dots being repeated in the Y direction for reading in a manner wherein the field of view of reading the pattern in the Y direction is less than the repeated pattern for a character.
Claim 3
Dependent Claim
16 words
The code of claim 1 wherein the dots are equally spaced in parallel rows and columns.
Claim 4
Dependent Claim
27 words
The code of claim 1 wherein the pattern includes a column of continuous dots and an adjacent blank column representing the start and finish of a code.
Claim 5
Dependent Claim
94 words
A machine readable high-density infor-mation printed code comprising a plurality of blocks of dots arranged in rows and columns in X and Y directions to form a pattern by means of parallel columns of dots repre-senting characters in the Y direction and conveying information by presence or absence of a dot at a specific location, said blocks of dots being repeated in the Y direction for reading in a manner wherein the field of view of reading the blocks in the Y direc-tion is less than the repeated blocks of dots for the characters.
Claim 6
Dependent Claim
94 words
A machine readable high-density infor-mation printed code comprising a plurality of blocks of dots arranged in rows and columns in X and Y directions to form a pattern by means of parallel columns of dots repre-senting characters in the Y direction and conveying information by presence or absence of a dot at a specific location, said blocks of dots being repeated in the Y direction for reading in a manner wherein the field of view of reading the blocks in the Y direc-tion is less than the repeated blocks of dots for the characters.
Claim 7
Dependent Claim
19 words
The code of claim 4 wherein the dots are equally spaced in parallel rows and columns in block form.
Claim 8
Dependent Claim
41 words
The code of claim 4 wherein the pattern includes a column of continuous dots in the Y direc-tion representing the start of a code and an absence of dots along a column in said direction representing the end of a code.
Claim 9
Dependent Claim
40 words
The code of claim 4 wherein the pattern of dots is repeated at least twice in the Y direction and reading is accomplished by viewing the pattern of dots substantially perpendicular to the rows of dots in the X direction.
Claim 10
Dependent Claim
44 words
The code of claim 4 wherein the pattern of dots is repeated at least twice in the Y direction and reading of the code is accomplished by optically sensing the pattern of dots substantially perpendicu-lar to the rows of dots in the X direction.
