Abstract

The invention relates to an X-ray apparatus comprising a holder (4) for X-ray film cassettes (8) which is mounted so as to be adjustable relative to the patients' couch (1). For scanning of the cassette dimensions, levers (10, 11) mounted so as to be pivotable on an axis (9) fixed on the apparatus are provided, which levers are drawn towards the cassette (8) as a result of spring tension and act upon one emitter (14, 15) each for an electrical signal corresponding to the particular position of the levers. The lever ends pressing against the cassette (8) are curved, so that the signal produced by the particular emitter (14, 15) is proportional to the cassette dimensions. <IMAGE>
