摘要: A hand held dataform reader for reading 1D and 2D bar codes matrix dataforms is disclosed. The includes a module having laser code assembly, codes, an imaging codes. further selection control circuitry energizing selected one of the assemblies. In operation, assembly energized first. If target code, decodable signal will be generated decoding decode dataform. not by turns off energizes assembly. or dataform, generate composite video representing image decodable,
