Abstract of the Disclosure An X-ray radiograph apparatus having a supply maga- zine, a film-removing unit, an X-ray imaging unit, a reference position detector, a suction detector, a dis- tance detector, a discriminator, and a display unit. The supply magazine contains a stack of unexposed films. The film-removing unit has a suction unit for holding a film and removing it from the magazine. The X-ray imag- ing unit forms an X-ray image of a subject on the film fed from the magazine by the film-removing unit. The reference position detector detects that the suction unit is passing a reference position located above the supply magazine. The suction detector detects that 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 suction detector. This distance is equal to the distance between said 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. The display unit displays the number of unexposed films, which has been determined by the discriminator.
