Abstract

A great number of bar codes are recorded in dual directions on a bar code information card. Each bar code is comprised of a plurality of bar symbols juxtaposed in parallel to each other. A plurality of bar codes, constituting one group bar code, are arranged in one direction which is orthogonal to the bar symbol and a plurality of group bar codes are arranged in the other direction in which the bar symbol extends. A great deal of bar-coded information is recognized by transferring the bar code information card in the longitudinal direction of the bar symbol and scanning the bar code orthogonally thereto.

Claims

1. A machine readable bar code information card comprising:

a card body which substantially has a uniform width;

a plurality of bar codes aligned parallelly to each other in a direction which is orthogonal to the longitudinal direction of said card body to constitute a group bar code, each bar code in said group bar code having a plurality of bar symbols which parallelly extend in the longitudinal direction of said card body and are in uniform length in different color and width; and

a plurality of group bar codes aligned parallelly to each other to form a recorded region which extends centrally in the longitudinal direction of said card body.

2. A machine readable bar code information card as claimed in claim 1, wherein said bar codes in each group bar code are spaced from each other by a first constant width, and wherein said group bar codes are spaced from each other by a second constant width.

3. A machine readable bar code information card as claimed in claim 1, wherein said group bar codes include respective index bar codes indicative of the group number at one side thereof.

4. A machine readable bar code information card as claimed in claim 3, wherein said index bar codes in the first and the last group bar codes among said a plurality of group bar codes have at least three wide bar symbols, and wherein said index bar codes in the remaining group bar codes have a fewer number of wide bar symbols than said index bar codes of the first and the last group bar codes.

5. A machine readable bar code information card as claimed in claim 1, wherein said group bar codes include a constant number of bar codes, and wherein the number of said group bar codes is more than that of said bar codes included in one group bar codes.

6. A machine readable bar code information arrangement comprising:

a body;

a plurality of bar codes arranged side by side on said body in a first direction to constitute a group bar code, each of said plural bar codes having seven bar symbols arranged side by side in said first direction, said seven bar symbols being recorded in first and second colors alternately and in first and second widths such that two of said seven bar symbols in respective first and second colors are in said first width and the remaining five of said seven bar symbols are in said second width; and

a plurality of group bar codes arranged parallelly to each other on said body in a second direction which is substantially orthogonal to said first direction.

7. A machine readable bar code information arangement as claimed in claim 6, wherein said first and second colors are contrasting in light reflectivity, and wherein said first width is 2.5 times wider than said second width.

8. A machine readable bar code information arrangement as claimed in claim 7, wherein the number of said bar codes in each of said group bar codes is smaller than the number of said group bar codes.

9. A machine readable bar code information arrangement comprising:

a body;

a plurality of index bar codes arranged in parallel with each other on said body in the longitudinal direction of said body, each of said index bar codes having seven bar symbols recorded side by side in black and in white alternately in a direction orthogonal to the longitudinal direction of said body, three and four bar symbols in the first and last of said index bar codes being recorded in respective wide and narrow widths, and two and five bar symbols in the other of said index bar codes being recorded in respective wide and narrow widths such that the other of said index bar codes represent numerical information in decimal integer order;

a plurality of numerical bar codes arranged side by side with each of said index bar codes in the direction orthogonal to the longitudinal direction of said body, each of said numerical bar codes having seven bar symbols recorded side by side in black and in white alternately in the same direction with the seven bar symbols of said index bar codes, and two and five bar symbols in each of said numerical bar codes being recorded in respective wide and narrow widths such that said numerical bar codes represent numerical information which is not in decimal integer order.
