Abstract
Abstract A computer uses a random number generator as the basis for formatting the number combinations of new bingo cards, and stores each new combination in memory. This proceeds until the number of generated and stored cards reaches a designated number, whereupon the computer scans the combinations in memory to detect duplicates, and removes combinations in such a way as to eliminate duplication. A high-spoeed, graphics printer, for example a laser printer, is then used and computer-controlled to print bingo cards on paper, using the number combinations in memory.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
224 words
A method for making bingo cards, comprising the steps: (a) generating a first plurality of random numbers utilizing the random number generating capability of a computer, (b) formatting on the basis of said first plurality of random numbers a first number combination for a first bingo card, utilizing the electronic processing capability of the said computer and a formatting program, (c) storing the first number combination for the first bingo card in an electronic or magnetic memory means, (d) generating a further plurality of random numbers utilizing the said random number generating capability, (e) formatting on the basis of said further plurality of random numbers a further number combination for a further bingo card, utilizing the electronic processing capability of the said computer and said formatting program, (f) storing the further number combination for the further bingo card in the memory means, (g) repeated steps (d), (e) and (f) in that order until the total of stored number combinations in the memory reaches a predetermined level, (h) using said electronic processing capability to scan the number combinations in the memory means in order to detect duplicates, (i) if required, removing number combinations from the memory means in order to eliminate duplication, and (j) using a computer-controlled, high-speed graphics printer to print bingo cards on paper, utilizing the number combinations remaining in the memory means.
Claim 2
Independent Claim
224 words
A method for making bingo cards, comprising the steps: (a) generating a first plurality of random numbers utilizing the random number generating capability of a computer, (b) formatting on the basis of said first plurality of random numbers a first number combination for a first bingo card, utilizing the electronic processing capability of the said computer and a formatting program, (c) storing the first number combination for the first bingo card in an electronic or magnetic memory means, (d) generating a further plurality of random numbers utilizing the said random number generating capability, (e) formatting on the basis of said further plurality of random numbers a further number combination for a further bingo card, utilizing the electronic processing capability of the said computer and said formatting program, (f) storing the further number combination for the further bingo card in the memory means, (g) repeated steps (d), (e) and (f) in that order until the total of stored number combinations in the memory reaches a predetermined level, (h) using said electronic processing capability to scan the number combinations in the memory means in order to detect duplicates, (i) if required, removing number combinations from the memory means in order to eliminate duplication, and (j) using a computer-controlled, high-speed graphics printer to print bingo cards on paper, utilizing the number combinations remaining in the memory means.
Claim 3
Dependent Claim
38 words
The method claimed in claim 1, in which step (h) is preceded by sorting the number combinations in memory, using the numbers of each number combination as a sort key, thereby facilitating the step of scanning for duplicates.
Claim 4
Dependent Claim
41 words
The method claimed in claim 2, in which step (j) includes first electronically or magnetically storing the generated number combinations which remain after the elimination of duplication, then transferring the stored number combinations to a computer controlling the high-speed graphics printer.
Claim 5
Dependent Claim
27 words
The method claimed in claim 1, in which after the elimination of duplication, the number combinations are converted electronically to a format acceptable to the printing program.
Claim 6
Dependent Claim
38 words
The method claimed in claim 4, in which step (h) is preceded by sorting the number combinations in memory, using the numbers of each number combination as a sort key, thereby facilitating the step of scanning for duplicates.
Claim 7
Dependent Claim
49 words
The method claimed in claim 5, in which step (j) includes first electronically or magnetically storing on tapes, disks or any other appropriate storage device the number combinations which remain after the elimination of duplication, then transferring the stored number combinations to a computer controlling the high-speed graphics printer.
Claim 8
Dependent Claim
15 words
The method as claimed in claim 6, in which the printer is a laser printer.
Claim 9
Dependent Claim
14 words
The method claimed in claim 1, in which the printer is a laser printer.
Claim 10
Independent Claim
132 words
An apparatus for making bingo cards, comprising: computer-controlled, high-speed graphics printing means, random number generating means for generating random numbers, an electronic processing means for formatting different number combinations of bingo cards on the basis of different random numbers, electronic or magnetic memory means for storing formatted number combinations as a batch, electronic counting means for counting the number combinations as they are being stored and for determining when the total of all stored number combinations in a batch reaches a predetermined level, electronic comparator means operative after said level has been reached for comparing each formatted number combination with other number combinations stored in the memory means, and for eliminating duplication, and means for causing the printer to manufacture bingo cards by printing groups of the number combinations on sheet material.
Claim 11
Independent Claim
132 words
An apparatus for making bingo cards, comprising: computer-controlled, high-speed graphics printing means, random number generating means for generating random numbers, an electronic processing means for formatting different number combinations of bingo cards on the basis of different random numbers, electronic or magnetic memory means for storing formatted number combinations as a batch, electronic counting means for counting the number combinations as they are being stored and for determining when the total of all stored number combinations in a batch reaches a predetermined level, electronic comparator means operative after said level has been reached for comparing each formatted number combination with other number combinations stored in the memory means, and for eliminating duplication, and means for causing the printer to manufacture bingo cards by printing groups of the number combinations on sheet material.
Claim 12
Dependent Claim
15 words
The apparatus claimed in claim 9, in which said printing means is a laser printer.
Claim 13
Dependent Claim
31 words
The apparatus claimed in claim 9, which further includes sorting means for sorting the stored number combinations using at least some of the numbers of each combination as a sort key.
Claim 14
Dependent Claim
41 words
The apparatus claimed in claim 9, which further includes magnetic storage means for storing a batch of number combinations from which duplication has been eliminated, said storage means permitting the number combinations to be transmitted to a computer controlling said printer.
Claim 15
Independent Claim
94 words
An apparatus for making bingo cards, comprising: high-speed graphics printing means, random number generating means for generating random numbers, an electronic processing means for formatting different number combinations of bingo cards on the basis of different random numbers, electronic or magnetic memory means for storing formatted number combinations, electronic comparator means for comparing each formatted number combination with the other number combinations stored in the memory means and for eliminating any duplication, and means for causing the printer to print groups of cards on paper, utilizing the number combinations stored in the memory means.
