    • 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.
    • 具有供给盒,薄膜除去单元,X射线摄像单元,基准位置检测器,吸引检测器,距离检测器,鉴别器和显示单元的X射线摄影装置。 供应盒包含一堆未曝光的胶片。 基准位置检测器检测抽吸单元何时通过位于供应盒上方的基准位置。 抽吸检测器检测片状膜何时被吸引到吸引单元。 距离检测器检测吸引单元从基准位置检测器和抽吸检测器的输出端垂直移动的距离。 该距离等于存储在盒中的基准位置与最高未曝光的胶片之间的距离。 鉴别器从由距离检测器检测的距离确定剩余在供应容器中的未曝光胶片的数量。
