    • A film cassette is disclosed wherein a spool includes two coaxial core pieces having a convoluted film roll coiled about them, whose outermost convolution is a film leader, and respective flanges fixed to the core pieces which radially extend over the opposite sides of the film roll. At least one of the core pieces is supported for movement axially toward the other one to move at least one of the flanges axially toward the other one to provide axial clamping forces at the opposite sides of the film roll. A film stripper-guide is received between the outermost convolution and the next-inward convolution of the film roll to strip the outermost convolution from the flanges and guide it through a film passageway to the exterior of the cassette shell responsive to rotation of the spool in a film unwinding direction during application of the axial clamping forces. According to the invention, at least one of the flanges includes integral means for concentrating the axial clamping forces substantially at the outermost convolution of the film roll and preventing application of the axial clamping forces substantially at the more-inward convolutions of the film roll.
    • 公开了一种胶片盒,其中卷轴包括两个同轴芯片,其具有围绕它们卷绕的卷曲膜卷,其最外卷积是膜引导件,以及固定到芯片的相应凸缘,其径向延伸超过膜卷的相对侧。 至少一个芯片被支撑成轴向移动到另一个,以将至少一个凸缘轴向移向另一个,以在胶卷的相对侧提供轴向夹紧力。 薄膜剥离器引导件被接收在最薄的卷积和胶片卷的下一个向内卷绕之间以从凸缘剥离最外圈,并且响应于卷筒的旋转而将其引导通过胶片通道到胶卷盒外部 在施加轴向夹紧力期间的膜退绕方向。 根据本发明,所述凸缘中的至少一个包括用于将所述轴向夹紧力基本上集中在所述胶片卷的最外圈处的集成装置,并且防止所述轴向夹紧力基本上在所述胶卷的更内向的卷取中施加。

    • In a film cassette, a spool is supported for rotation in an unwinding direction inside a cassette shell, a convoluted film roll whose outermost convolution is a film leader is coiled in the unwinding direction about the spool, and a film stripper is located substantially adjacent a passageway to the exterior of the shell to be received between a leading end of the film leader and a next-inward convolution of the film roll responsive to rotation of the spool in the unwinding direction to divert the leading end into the passageway. According to the invention, the stripper is positioned to lie against the next-inward convolution of the film roll to generally ensure the stripper will be received between the leading end of the film leader and the next-inward convolution when the spool is rotated in the unwinding direction.
    • 在薄膜盒中,卷轴被支撑用于在盒壳体内沿展开方向旋转,卷绕卷膜的卷绕卷膜卷绕卷绕卷绕卷轴的卷绕方向,并且膜剥离器基本上邻近 通向外壳的通道,以容纳在胶片引导件的前端与胶卷之间的向下卷绕,以响应卷轴在展开方向上的转动,将前端转入通道。 根据本发明,剥离器被定位成抵抗胶片卷的下一个向内卷绕,以大体上确保当卷轴旋转时,剥离器将被接收在胶片引导件的前端和下一个向内的卷积之间 展开方向。
