Abstract
An X-ray film cassette has on its top a triangular bar code field readable by a bar code reader of an automatic film sheet charging and discharging apparatus. The bar code field is in the form of an isosceles right triangle whose hypothenuse faces a reference corner and whose legs extend parallel to edges of the cassettes. The bars of the code extend parallel to the hypothenuse. An optical axis of the bar code reader, when the cassette is in its end position in the apparatus, intersects a vertex area formed by the legs of the triangle. This arrangement guarantees that its bar codes on cassettes of small format, even if misaligned in the feeding direction, are reliably read by the reader.
