ABSTRACT:
Optical reader apparatus for reading data on a data carrier. A housing defines a data carrier slot having an optical data window at a prearranged position. An optical reading means is mounted within the housing for reading data scanned past the optical data window. A door assembly is mounted in a hinged relation to the housing means opposite the optical read window. The door has closed and open positions and permits access to the optical data window in the open position. The door assembly carries a resilient pressure spring. The resilient pressure spring urges a data carrier passing through the data carrier slot into optical reading contact with the optical data window. The door assembly mounts the resilient spring member within a frame for easy removability. The resilient pressure spring carries an optical compensation member on a forward surface thereof so that the optical compensation member is presented to the optical data window when a data carrier is not present.
