Abstract
A data symbol reading device is provided with a white light source, a single-color LED light source, and mode selection switches.

The reading device transmits data as appropriate to a host computer. Alternatively, the symbol reading device is provided with red, green, and blue single-color light sources, and has the same modes. Further, the symbol reading device may be provided with a three or four color filter wheel and a white light source to generate the color and monochrome images.
