Abstract
Abstract In a bar code printer, the type of bar code and widths of bar code elements are input into an input unit (4, 5, 12). A control circuit (1) selects one of ROM pattern generators (2A-2D) according to the bar code type input, and develops the bar code patterns by adjusting the widths of all the bar code elements included in each bar code pattern according to the element widths input. The results are buffered (3C), then printed (7). <IMAGE>

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A bar code printer comprising:
a printing section;
memory means having memory areas respectively serving as pattern generators for generating various bar code patterns and a memory area serving as a printing buffer;
input means for inputting the type of bar code and the width of at least one bar code element; and
control means for selecting one of said pattern generators according to the bar code type input via said input means, causing the selected pattern generator to sequentially generate bar code patterns of desired characters, developing the bar code patterns generated from the selected pattern generator by adjusting the widths of all the bar code elements included in each bar code pattern according to the element width input via said input means, storing, as a printing pattern of the bar code, the developed bar code patterns in said printing buffer, and causing said printing section to print the printing pattern stored in said printing buffer.
Claim 2
Dependent Claim

control means for selecting one of said pattern generators according to the bar code type input via said input means, causing the selected pattern generator to sequentially generate bar code patterns of desired characters, developing the bar code patterns generated from the selected pattern generator by adjusting the widths of all the bar code elements included in each bar code pattern according to the element width input via said input means, storing, as a printing pattern of the bar code, the developed bar code patterns in said printing buffer, and causing said printing section to print the printing pattern stored in said printing buffer.
Claim 3
Dependent Claim
42 words
A printer according to claim 1, wherein said control means includes a control circuit for setting the bar code elements of each bar code pattern to have widths input via said input means, said widths being specified by the numbers of dots.
Claim 4
Dependent Claim
59 words
A printer according to claim 2, wherein said control circuit includes means for determining the width of another bar code element by multiplying the element width input via said input means by a preset number when the bar code is of a type in which the ratio of the widths of bar code elements are determined by a standard.
Claim 5
Dependent Claim
37 words
A printer according to claim 1, wherein said control means includes means for converting the element width input via said input means to the number of dots with reference to the printing density of said printing section.
Claim 6
Dependent Claim
32 words
A printer according to claim 1, wherein said bar code pattern is formed of a combination of bar code elements selected from a narrow bar, wide bar, narrow space, and wide space.
Claim 7
Dependent Claim
14 words
A printer according to claim 1, wherein said printing section includes a thermal head.
Claim 8
Dependent Claim
19 words
A bar code printer, substantially as hereinbefore described with reference to Figs. 3 to 5B of the accompanying drawings.
Claim 9
Dependent Claim
19 words
A bar code printer, substantially as hereinbefore described with reference to Figs. 3 to 5B of the accompanying drawings.
