Abstract
A bar code scanner includes a detection unit for detecting light reflected from a bar code and generating a detection signal, a conversion unit for generating detected bar code data based on the detection signal, an input interface unit receiving external bar code data generated externally, a data control unit for generating output bar code data by using the detected bar code data and/or the external bar code data from the input interface unit, and an output interface unit for sending out the output bar code data.
Claims18
A bar code scanner comprising:
- detection means for detecting light reflected from a bar code and generating a detection signal;
- conversion means for generating detected bar code data based on said detection signal;
- an input interface unit receiving external bar code data from another bar code scanner connected thereto;
- data control means for combining said detected bar code data and said external bar code data to generate combined bar code data and for providing one of said detected bar code data, said external bar code data, and said combined bar code data as output bar code data;
- and
- an output interface unit for sending out said output bar code data.
A bar code scanner comprising:
- detection means for detecting light reflected from a bar code and generating a detection signal;
- conversion means for generating detected bar code data based on said detection signal;
- an input interface unit receiving external bar code data generated externally;
- data control means for generating output bar code data by either combining said detected bar code data and said external bar code data or providing said detected bar code data or said external bar code data by switching between said detected bar code data and said external bar code data;
- and
- an output interface unit for sending out said output bar code data.
A bar code scanning system comprising a plurality of bar code scanners, each of which comprises:
- detection means for detecting light reflected from a bar code and generating a detection signal;
- conversion means for generating detected bar code data based on said detection signal;
- an input interface unit receiving external bar code data generated externally;
- data control means for generating output bar code data by using said bar code data and/or said external bar code data from said input interface unit;
- and
- an output interface unit for sending out said output bar code data;
- wherein said bar code scanners are cascaded by connecting said output interface unit of one bar code scanner with said input interface unit of another bar code scanner.
