    • A film sheet load magazine is adapted to hold a stack of superimposed films with at least central portions of the films in a curved configuration and leading ends of the films adjacent a film separator mechanism. The curvature of the films is such that they retain themselves in desired positions in the magazine independent of the orientation of the films with respect to gravity. When a top cover of the magazine is opened, floating primary feed rollers are raised by spring-biasing assemblies to facilitate loading of the films under the rollers, and when the top cover is subsequently closed, the rollers are moved into feeding engagement with an innermost film, and the films are held in position by leaf biasing springs. A cleaning mechanism removes contaminants from the primary feed rollers, which feed each film to secondary feed rollers driven at a faster speed than the primary feed rollers. A number-of-films-remaining mechanism, which may be of a mechanical or electrical type which is adjustable for films of different thicknesses, and which is automatically preset to the number of films in the magazine upon closing of the cover, is responsive to downward movement of the primary feed rollers as each innermost film is fed from the stack. A system also is provided for indicating if enough films remain in the magazine for a particular film processing operation and to inhibit operation of an associated device if insufficient films remain. The magazine may be self-driven or driven from an associated device.
    • 薄膜片装载盒适于将至少中心部分的膜的叠加的薄膜的一叠叠放在弯曲构型中,并且薄膜的前端邻近薄膜分离器机构。 膜的曲率使得它们保持它们独立于胶片相对于重力的取向而在胶带中的期望位置。 当打开杂志的顶盖时,浮动的主馈送辊由弹簧偏置组件升高以便于将膜下载到辊下方,并且当顶盖随后关闭时,辊被移动到与最内侧的进料接合 薄膜,并且薄膜通过叶偏压弹簧保持就位。 清洁机构从主进料辊中除去污染物,这些污染物将每个胶片送到以比主进料辊更快的速度驱动的二次进料辊。 可以是可以为不同厚度的膜调节的机械或电气类型的数字电影剩余机构,并且其在盖封闭时自动预设为盒中胶片的数量,其响应于 当每个最内层的薄膜从堆叠进料时,主进料辊的向下运动。 还提供了一种系统,用于指示在特定胶片处理操作中是否有足够的胶片残留在胶卷盒中,如果剩余的胶片不足,则禁止相关装置的操作。 杂志可以是自驱动的或者是从相关联的设备驱动的。
