Abstract
A reader comprises a feeding path for boarding pass to be inserted in various orientations, pairs of feeding rollers for transporting the boarding pass along the path, and four sensor units arranged along the path each for sensing a signal recorded on the boarding pass inserted in a particular orientation. The reader also comprises a demodulation unit for demodulating each signal sensed by the sensor units, a monitoring circuit for determining which one of the sensor units of has sensed the recorded signal, a switch circuit, for electrically connecting the demodulation unit to the sensor unit which the monitor circuit determines has sensed the recorded signal, and a read circuit for reading flight information by extracting a series of digital data from each demodulated signal output by the demodulation unit and converting the series of digital data into the parallel form in accordance with the particular orientation of the boarding pass facing the sensor unit which the monitor circuit determines has sensed the recorded signal.
