Abstract: An X-ray radiograph apparatus comprises means for detecting a number of remaining unphotographed recording media retained in a recording-medium feed magazine, and display means for displaying the number of remaining unphotographed recording media detected by the detecting means with scales which change logarithmically and multiple display elements arranged in association with the scales.

Abstract: In an X-ray equipment, a photographing program including a plurality of photographic formats is stored in advance. Program photographing is performed in accordance with the photographic formats read out in a predetermined order. When an interrupt signal is input during program photographing, a read operation of the photographic formats is temporarily interrupted, and photographing is performed in accordance with a newly input photographic format. In addition, when a skip signal is input during program photographing, the read out photographic format is cancelled, and program photographing is performed in accordance with the next photographic format.

Abstract: A film feeder of a cassettes X-ray photographic apparatus comprises a plurality of suction cups capable of attracting unexposed film in a first and second magazines receiving unexposed film of different sizes, first guide path for guiding the cups between the first magazine and a feed mechanism which feeds unexposed film to a holder section, a second guide path for guiding the cups between the second magazine and feed mechanism, and a drive control mechanism for moving the cups attracting unexposed film from the first and second magazine to the holder along the first and second guide path selected optionally. The cups are moved in a vertical, slant and horizontal direction by the drive control mechanism.

Abstract: An X-ray radiography apparatus having a supply magazine, a film-removing unit, an X-ray imaging unit, a reference position detector, a suction detector, a distance detector, a discriminator, and a display unit. The supply magazine contains a stack of unexposed films. The reference position detector detects when the suction unit passes a reference position located above the supply magazine. The suction detector detects when a sheet film has been attracted to the suction unit. The distance detector detects the distance the suction unit has moved vertically, from the outputs of the reference position detector and the suction detector. This distance is equal to the distance between the reference position and the topmost unexposed film stored in the magazine. The discriminator determines the number of unexposed films remaining in the supply vessel from the distance detected by the distance detector.
