ABSTRACT:
A data card reader for an electronic apparatus is arranged to read an optical pattern printed upon a data card. The reader includes a card transport assembly to move the data card along a path and a reading assembly that traverses the path to read the pattern. The reading assembly is comprised of an elongate body of transparent material formed with an elongate lens and a parallel series of discrete lenses. A series of LEDs is mounted within the body below the elongate lens and similarly a series of CCD optical sensors is mounted beneath the series of discrete lenses. In use, light from the LEDs is focused on the data card by the elongate lens and reflected back onto the discrete lenses. The discrete lenses in turn focus the reflected light onto the CCD optical sensors. Output from the sensors is coupled to a processor which operates to decode the pattern. By forming both the elongate lens and the discrete lenses out of a single piece of transparent material a simple and easily constructed reader is provided.
