Abstract
Abstract A bar code printer is disclosed which may be used as a standard desk type bar code printer, a weighing bar code printer, etc. by connecting outer peripheral equipment, such as weighing instruments or price indicating balances, to the bar code printer. A change-over circuit can select an input signal from either the input unit of the bar code printer or from the outer peripheral equipment, the input signal energizing a control circuit which develops control signals to drive a bar code printing system and an indicating system. The printer has differing types of bar code systems stored therein and by entering a flag code, a specific bar code system may be selected. Also, the differing types of bar code systems may be accomodated since the bar code is divided into a fixed part (for common use in all systems) and a variable part (differing numerals between bar code systems). The column numbers of the variable part of the bar code may be identified prior to introducing print data via the input unit and the numerals from the input for the variable part may be input thereinto. The printing system includes a plurality of heating elements which contact a heat sensitive surface of the labels. This causes the printing of the bars on the bar code label. The control circuit may include means for maintaining a constant, uniform width of the bars on the bar code label.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
A bar code printer for producing bar code labels, comprising: an input unit means for introducing required input data into said bar code printer, said input data including prescribed numerals, and developing an input signal of prescribed form in accordance therewith; signal control system means responsive to said input signal for developing control signals in response thereto; bar code printing system means responsive to said control signals for printing said bar code labels in a specified format in accordance with said control signals, said bar code labels having columns designated as a fixed part and columns designated as a variable part, selected ones of said prescribed numerals in said input data being associated with the columns for the fixed part, and other selected ones of said prescribed numerals in said input data being associated with the columns of the variable part in response to identification by said input data introduced via said input unit means and an indicating system operatively responsive to said signal control system with display means responsive to said control signals for displaying the identified column numbers of the columns of the variable part, as distinguished from the fixed part.
Claim 2
Dependent Claim
193 words
A bar code printer for producing bar code labels, comprising: an input unit means for introducing required input data into said bar code printer, said input data including prescribed numerals, and developing an input signal of prescribed form in accordance therewith; signal control system means responsive to said input signal for developing control signals in response thereto; bar code printing system means responsive to said control signals for printing said bar code labels in a specified format in accordance with said control signals, said bar code labels having columns designated as a fixed part and columns designated as a variable part, selected ones of said prescribed numerals in said input data being associated with the columns for the fixed part, and other selected ones of said prescribed numerals in said input data being associated with the columns of the variable part in response to identification by said input data introduced via said input unit means and an indicating system operatively responsive to said signal control system with display means responsive to said control signals for displaying the identified column numbers of the columns of the variable part, as distinguished from the fixed part.
Claim 3
Dependent Claim
28 words
A bar code printer in accordance with claim 1 wherein said display means comprises a plurality of indicator tubes for providing a dot display and a dash display.
Claim 4
Dependent Claim
19 words
A bar code printer in accordance with claim 1 wherein said bar code printer comprises a price tag printer.
Claim 5
Independent Claim
175 words
A method for setting bar code in a bar code printer, said bar code printer including an input unit, a signal control system operatively responsive to said input unit, a bar code printing system and an indicating system operatively responsive to said signal control system, said signal control system including a memory unit for storing various types of code systems for said bar code therein, each of said code systems determining the construction of the bar code set in said bar code printer, said method comprising the steps of: entering required input data into said bar code printer via said input unit, said input data including a flag for determining which of said code systems stored in said memory unit should be selected for ultimate determination of the construction of said bar code set in said bar code printer wherein said bar code is registered in said bar code printer by actuating a 10-numeral key on said input unit; calculating a completion check digit; and displaying said calculated completion check digit on said indicating system.
Claim 6
Independent Claim
175 words
A method for setting bar code in a bar code printer, said bar code printer including an input unit, a signal control system operatively responsive to said input unit, a bar code printing system and an indicating system operatively responsive to said signal control system, said signal control system including a memory unit for storing various types of code systems for said bar code therein, each of said code systems determining the construction of the bar code set in said bar code printer, said method comprising the steps of: entering required input data into said bar code printer via said input unit, said input data including a flag for determining which of said code systems stored in said memory unit should be selected for ultimate determination of the construction of said bar code set in said bar code printer wherein said bar code is registered in said bar code printer by actuating a 10-numeral key on said input unit; calculating a completion check digit; and displaying said calculated completion check digit on said indicating system.
