摘要： A film magazine comprised of a cylindrical portion and a pair of end covers is provided with film speed indicating code means. The cylindrical portion of the film magazine is made of metal sheet applied with an insulating coating layer. The surface of the cylindrical portion is selectively provided with non-coated sections for indicating the film speed of the film loaded therein in accordance with a binary code system. The code which indicates the film speed is sensed by a small number of sensing contacts provided in the camera body. The non-coated sections for indicating the film speed are located in the inaccessible area of the film magazine so that the coding sections may not be damaged.

摘要： A lens-fitted photo film unit has photo film pre-contained in a photo film containing section (14, 70). An exposure is taken on the photo film via a photographic light path (20). An electronic flash device (16) is secured in front of the photo film containing section. The electronic flash device includes a circuit board (27, 69) having a flash circuit, a flash-emitting section, and a charge switch for charging the flash circuit. The charge switch includes two contact points (32a, 32b, 69a, 69b) and a movable switch segment (33, 68a) for contact with the contact point to switch on charging of the flash circuit. A front cover (18, 60, 91) is secured to cover a front of the circuit board. The switch segment is depressible for coming in contact with the contact point. An operable lever (12, 63, 94) is associated with the front cover in rotatable fashion between an erected position and a folded position relative to the front cover. The switch segment is kept depressed when the operable lever has the erected position.
摘要翻译： 带镜头的摄影胶片单元具有预先包含在摄影胶片容纳部分（14,70）中的照相胶卷。 通过照相光路（20）对摄影胶片进行曝光。 电子闪光装置（16）固定在摄影胶片容纳部分的前面。 电子闪光装置包括具有闪光电路的电路板（27,69），闪光发射部分和用于对闪光电路充电的充电开关。 充电开关包括两个接触点（32a，32b，69a，69b）和可动开关段（33,68a），用于与触点接触以开启闪光电路的充电。 前盖（18,60,91）被固定以覆盖电路板的前部。 开关段可以与接触点接触而压下。 可操作的杆（12,63,94）以可旋转的方式与前盖相关联，在竖立位置和相对于前盖的折叠位置之间。 当可操作的杠杆具有竖立位置时，开关段保持按压。

摘要： A lens-fitted photographic film package, some of whose parts are designed to be directly reused. A projection is formed integrally with a molded resin part of the package body which is to be reused. The projection is brought into contact with another part of the film package and elastically deformed by that part when assembled into the package body. If the molded resin part is in normal condition suitable for reuse, the projection elastically recovers its initial shape when the parts are disassembled. Whether the predetermined parts of the package body can be directly reused or not is determined by detecting heat distortion of the projection. A referential projection, which is never distorted and so maintains its initial shape, is formed beside the elastically deformed projection.
摘要翻译： 配有镜头的摄影胶片包装，其中一些部件被设计为直接重复使用。 突起与要重复使用的封装体的模制树脂部分整体形成。 突起与膜包装的另一部分接触并且当组装到包装体中时由该部分弹性变形。 如果模制树脂部件处于适合重新使用的正常状态，当拆卸部件时，突起弹性地恢复其初始形状。 通过检测突起的热变形来确定包装体的预定部分是否可以直接重复使用。 在弹性变形的突起之外形成从未变形并保持其初始形状的参考突起。

摘要： A film initial-advance apparatus advances, after a film cassette is loaded, a film leader portion protruding from the film cassette toward a film take-up spool. A drive lever moves as the film take-up spool rotates. The drive lever causes a film threading member to reciprocally and intermittently move along a film passageway. The film threading member engages with a perforation of the film leader portion to intermittently advance the film leader portion. When the film leader portion is fully captured by the film take-up spool, the drive lever is pushed outside in the axial direction of the film take-up spool by the side edge of the film leader portion, thereby disengaging the drive lever from the film take-up spool. The film threading member rotates while moving in the radial direction, having a large radius of rotation of the claw over the range wherein it engages a perforation of the film leader portion and a smaller radius elsewhere.

摘要翻译： 胶片初始提前装置在胶卷盒装载之后前进到从胶片暗盒向胶片收卷卷轴突出的胶片引导部分。 驱动杆随着胶卷卷轴旋转而移动。 驱动杆使得薄膜穿线构件沿薄膜通道往复并间歇地移动。 薄膜穿线构件与薄膜引导部分的穿孔接合以间歇地推进薄膜引导部分。 当胶片引导部分完全被胶片卷取卷轴捕获时，驱动杆通过胶片引导部分的侧边沿胶片卷取卷轴的轴向被推向外部，从而将驱动杆从 胶卷卷轴。 薄膜穿线构件在向径向移动的同时旋转，具有爪的转动半径大于其与胶片引导部的穿孔接合的范围，而其他位置具有较小的半径。

摘要： Conventionally, color films must be used with the light source or illumination for which it was designed, such as for natural daylight, fluorescent-light or tungsten-light or, if used with another light source, a suitable conversion filter must be placed over the camera lens. However, an improvement in the emulsion of the film provide an improved type of film with which good printed images are available through a mere correction during printing of the film. The present invention provides a method and a device for detecting and recording the type of illumination through detection of their spectral properties and detection of existence of a flickering noise due to an alternating voltage of the commercial power supply, and a system for an automatic film development.
摘要翻译： 通常，彩色胶片必须与其设计的光源或照明一起使用，例如用于自然采光，荧光灯或钨光灯，或者如果与其他光源一起使用，则必须将合适的转换滤光片放置在 镜头。 然而，膜的乳液的改进提供了一种改进型的膜，通过在胶片的印刷期间仅仅进行校正，可以获得良好的印刷图像。 本发明提供一种检测和记录照明类型的方法和装置，该方法和装置通过检测它们的光谱特性并检测由商用电源的交流电压引起的闪烁噪声的存在以及用于自动胶片显影的系统 。
