ABSTRACT:
An optical reader includes a mechanical scanning assembly for scanning an optical card such as an OC-ROM. The scanning assembly includes a linear LED array, a linear detector array and a carrier for moving the LED array and the detector array jointly in a linear scanning direction. When the LED array illuminates a data patch on the optical card, a bit image of the data patch is focused onto the detector array. The bit image is read out as a serial stream of data. A data patch can be randomly accessed by moving the scanning assembly to a row including the data patch and turning on an LED located over the data patch.
