    • A fun camera provides precise registration of a latent image within a film frame with subsequent images placed on the filmstrip (16) through exposure of the filmstrip within the camera. Rolls of film (16) are pre-exposed with the latent image of artwork positioned within film frames. Masks are provided for insertion of the camera frame opening for shielding that portion of the film frame which contains the artwork latent image. The artwork is placed onto the pre-exposed filmstrip using an imaging filmstrip (12) formed in a continuous loop. The continuous loop having multiple artwork images (82) thereon is rotated while a portion of the filmstrip is in contact with a portion of the bulk film for contact printing the artwork image from the filmstrip to the bulk film. The pre-exposed bulk roll of film is punched (98) at preselected sprocket holes (96) corresponding to the filmstrip length for providing a reference sprocket hole within each length of film cut from the bulk roll for loading within canisters for use within the fun camera for exposure of a second latent image in juxtaposition with the artwork. Improvements to the fun camera film advancing mechanism include a ratchet-type sprocket and permit precise movement of the film, indexing of the film using a sprocket hole count for providing improved registration of the multiple images juxtaposed within the film frames, and daylight loading of the film.
    • 有趣的相机通过曝光照相机内的胶片,提供胶片框内的潜像的精确配准以及放置在胶卷(16)上的随后图像。 胶卷(16)的卷子预先曝光,图像位于胶片框架内。 提供掩模用于插入相机框架开口,用于屏蔽包含艺术品潜像的胶片框架的那部分。 使用形成在连续环路中的成像胶片(12)将艺术品放置在预曝光的胶卷上。 在其上具有多个图案图像(82)的连续环路旋转,同时一部分胶片与本体膜的一部分接触,用于将图像图像从胶卷接触印刷到散装胶片。 预先暴露的薄膜卷片(98)在对应于胶片长度的预选链轮孔(96)处冲压(98),用于在从胶卷切割的胶片的每个长度内提供参考链轮孔,用于加载到罐内以在乐趣中使用 曝光第二潜像的相机与艺术品并置。 有趣的相机胶片推进机构的改进包括棘轮式链轮,并且允许胶片的精确移动,使用链轮孔数目对胶片进行索引,以提供并排在胶片框架内的多个图像的改进配准,以及 电影。
