AUTOMATICALLY LOADED AND UNLOADABLE X-RAY FILM CASSETTE AND READY-TO-USE X-RAY CASSETTE LOADING AND UNLOADING DEVICE

摘要

An apparatus for automatic charging and discharging an X-ray film sheet into a cassette includes a bar code reader having an illumination device and a rotary scanning mirror. The cassette is provided on its top with a bar code label which irrespective of the format of the cassette is always located at a fixed distance from a leading edge and from a lateral guiding edge of the cassette. The cassette is insertable into an intake compartment and only after the cassette reaches an end position in the compartment a limit switch activates the scanning mirror and the illumination device of the reader, thus eliminating reading errors when reading bar codes on cassettes of different formats.
