    • A prism positioned behind the objective rotates at a predetermined frequency. The pulsed light beam produced thereby is split into a first and second pulsed beam, each falling on a photoelectric transducer element. The first photoelectric transducer element is positioned at a distance from the objective which is less than the distance between the film plane and the objective plane by a predetermined distance. The second photoelectric transducer is positioned away from the objective by a distance exceeding the distance between the film plane and the objective plane by the same predetermined distance. The first and second electrical signals produced by the first and second photoelectric transducer are differentiated and stored. The so-stored signals are compared and a control signal for driving a motor in a first or second direction is furnished corresponding to the difference therebetween. The motor drives the objective either closer to or away from the film plane in response to the control signal.
    • 位于物体后面的棱镜以预定的频率旋转。 由此产生的脉冲光束被分成第一和第二脉冲光束,每个脉冲光束落在光电换能器元件上。 第一光电传感器元件被定位成距离物镜一定距离,该距离小于膜平面和物平面之间的距离预定距离。 第二光电传感器远离物镜远离镜片平面与物镜之间的距离相同预定距离。 由第一和第二光电变换器产生的第一和第二电信号被差分并存储。 比较如此存储的信号,并且根据它们之间的差异来提供用于驱动电动机沿第一或第二方向的控制信号。 响应于控制信号,马达驱动物镜更靠近或远离胶片平面。

    • A photographic roll-film pack, comprised of a light-proof core case with roll-film, with a photographic shutter, film advance means with manual control, a picture counter, a shutter-release device and apertures and/or lenses of a picture-taking lens and/or viewfinder defining optical beam paths, with a covering for the core case which leaves uncovered at least one manual control, is designed so that the covering is formed by a protective case (11, 12), enclosing the core case (1, 2), which is composed of shells (11, 12) of essentially rigid plastics which is at least transparent in the areas of apertures and/or lenses of a picture-taking lens and/or viewfinder defining optical beam paths. The roll-film pack is thereby protected against moisture, dirt and damage, but can still be manufactured cost-effectively using automated production and it can be re-assembled following removal of an exposed film.

    • A photographic copying machine wherein the images of successive frames on a long roll of spliced-together exposed and developed customer films are copied while successive films are advanced stepwise from a supply reel on a first driven mandrel toward and is convoluted on a takeup reel on a second driven mandrel. The copying machine employs a third mandrel which can support a fresh roll in the plane of the roll on the first mandrel, and a fourth mandrel which can support an empty takeup reel in the plane of the rotating takeup reel. The leader of the fresh roll is located adjacent the film path ahead of the copying station and is automatically advanced into the range of an automatic attaching mechanism when the trailing end of the expiring roll has advanced beyond the copying station. The attaching mechanism secures the leader of the fresh roll to the core of the empty takeup reel, and the machine is then ready to make copies of frames forming part of the fresh roll. The filled takeup reel on the second mandrel is replaced with an empty takeup reel and a fresh roll is placed onto the first mandrel while the machine copies the frames of the roll which is supported by the third mandrel and is convoluted on the takeup reel on the fourth mandrel.
    • 一种照相复印机,其中在长时间拼接在一起的已曝光和显影的客户胶片上的连续帧的图像被复印,而连续的胶片从第一驱动的心轴上的供应卷轴逐步前进并且卷绕在卷绕卷轴上 第二驱动心轴。 复印机采用第三心轴,其可以支撑在第一心轴上的辊的平面中的新卷,以及第四心轴,其可以支撑旋转的卷取卷轴的平面中的空卷绕卷轴。 新卷的前端位于复印台前面的胶片路径附近,当到期辊的后端超出复印台时,自动前进到自动连接机构的范围。 连接机构将新卷的前端固定到空的卷绕卷轴的芯部,然后机器准备复制形成新卷的一部分的框架。 在第二心轴上的填充卷绕卷轴被替换为空的卷绕卷轴,并且将新卷放置在第一心轴上,同时机器复制由第三心轴支撑并卷绕在卷绕卷轴上的卷的框架 第四个心轴。

    • A novel film cartridge, camera for use with such cartridge and method of making such cartridge are disclosed. The cartridge is in form of a pocket of a material which is impermeable to light and which accommodates a multi-exposure film strip having a length at least equal to the length of the pocket. The pocket is provided with at least one opening extending transversely to its elongation and through which a leading end of the film strip extends to the exterior of the pocket so that it can be engaged by a film transporting mechanism of a camera suitable for accommodating such a pocket, which mechanism transports the film strip either in one continuous movement out of the pocket and into a storage space of the camera from where it is sequentially transported into the pocket in increments during which exposures are made, or else the film is sequentially transported out of the pocket and into the camera storage space with exposures being made during each transporting step and the exposed film is thereupon returned in a single movement into the pocket. However, the pocket may also have two parts one of which accommodates the non-exposed film strip which is then transported during exposures into the other part so that the film strip becomes completely located in the other part when it is fully exposed and a re-transportation into the first part of the pocket is not necessary. Cameras suitable for use with various embodiments of the novel cartridge are also disclosed, as well as methods of making the cartridge.
    • 公开了一种新颖的胶片暗盒,用于这种盒的相机以及制造这种盒的方法。 药筒是一种不透光材料的口袋的形式,并且容纳多个曝光胶带,其长度至少等于口袋的长度。 该口袋设置有至少一个横向延伸的开口,该薄膜条的前端延伸到该口袋的外部,从而可以通过适合于容纳这种类型的相机的照相机的胶片传送机构来接合 口袋,该机构以一个连续的运动将口袋中的胶片带传送出照相机的存储空间,并在其中以增量的顺序传送到口袋中,在曝光期间,或者将胶片依次传送出去 并且在每个输送步骤期间进行曝光并进入相机存储空间,并且曝光的胶片随后以单次运动返回到口袋中。 然而,口袋还可以具有两个部分,其中一个容纳未曝光的胶片条,然后在曝光期间将其转印到另一部分中,使得当胶片条被完全曝光时,胶片条完全位于另一部分中, 运输到口袋的第一部分是没有必要的。 还公开了适用于新型盒的各种实施例的相机以及制造盒的方法。
