Abstract
An optical sensing member for reading a coded member having parallel aligned tracks of data and clocking coded symbols which includes a pair of sensing apertures offset to enable the sensing of the data track to occur out of phase with the sensing of the clocking track. The sensing member includes a housing having a sensing surface in which the offset apertures are located, a light source, a pair of photo-transistors for sensing the tracks of coded symbols and optical fibers for transmitting light from the light source to the tracks of coded symbols and the reflected light to the photo-transistors for the reading of the coded members.
