摘要： An exposure aperture frame defining an exposure aperture includes at least a pivotable partition member with an inclined guide surface on the inner wall thereof which is pivoted by and thereby permits advancement of a film leader to a film take-up chamber so that the film leader can reach a film take-up chamber without any standstill within the exposure aperture frame. The inclined guide surface permits the forward end of the film leader to ride across the partition member. A spring urges the partition member toward a position in which it encloses the exposure aperture frame. That spring also releasably retains the partition member on a shaft on which it is pivoted. The partition member has a platform member extending toward the take-up chamber, which has an opening therethrough that provides access to the spring.

摘要翻译： 限定曝光孔的曝光孔框架包括至少一个可枢转的分隔构件，其在其内壁上具有倾斜的引导表面，所述倾斜的引导表面由其转动并由此允许胶片引导者前进到胶片拾取室，使得胶片引导件 在曝光孔眼框架内没有任何静止的情况下到达胶片吸收室。 倾斜的引导表面允许胶片引导件的前端穿过分隔件。 弹簧将分隔构件推向其包围曝光孔框架的位置。 那个弹簧也可以将分隔件可释放地保持在其上枢转的轴上。 分隔构件具有朝向卷取室延伸的平台构件，该平台构件具有穿过其的开口，其提供通向弹簧的通路。
