    • A lens-fitted photographic film package has a talking lens, a shutter and a film advancing mechanism incorporated therein and is loaded with film. The taking lens is disposed at the upper side of a casing of the film package and a first mirror is disposed behind the taking lens. A second mirror is disposed below the taking lens inside the casing. A Z-shaped exposure light path is thus formed by the first and second mirrors. On the inner wall surface of an exposure chamber for conducting the exposure light, there are formed a number of ridges extending in a direction parallel to the path of travel of the exposure light which reduce internal reflection within the exposure chamber. The mirrors are pressed by respective mirror hold-down members from the outside against respective mirror frames, and the mirror hold-down members are shaded with respective shading covers from ambient light.
    • 具有透镜的摄影胶片包装装有透镜,快门和胶片推进机构,其中装有胶片。 拍摄镜头设置在胶片包装的壳体的上侧,并且第一反射镜设置在拍摄镜头的后面。 第二反射镜设置在外壳内的拍摄镜头的下方。 因此,由第一和第二反射镜形成Z形曝光光路。 在用于进行曝光的曝光室的内壁表面上,形成有多个脊,该脊在与曝光灯的行进路径平行的方向上延伸,从而减少曝光室内的反射。 镜子被相应的镜子按压构件从外部压到相应的镜框上,并且镜子压紧构件被遮蔽物与相应的阴影遮盖物遮蔽环境光。
