摘要： A film cassette assembly has a cassette and a roll of film wound on a spool and contained in the cassette. When the spool is rotated, the roll of film is rotated together with it in order to feed a film leader out of the cassette through a film passage mouth. To rotate the spool and the roll of film together, the film cassette assembly presses an axial end portion of the outermost periphery of the roll of film or presses the film's circumferential peripheral surface. Where the axial end portion of the outermost periphery of the roll of film is to be pressed, at least one of a pair of flanges of the spool is elastically deformed to clamp both axial side edges of the outermost periphery of the roll of film. Where the circumferential surface of the outermost periphery of the roll of film is to be pressed, a projection and an elastic member are provided within the cassette.

摘要： A self-advancing film cassette is provided with an auxiliary rotation transmittance structure for reliably transmitting rotation of a spool to the inner turns of a roll of film in order to prevent reverse rotation of the film caused by loosening of the inner turns of the roll of film or inferior bending rigidity. According to one preferred embodiment, a step portion for pushing the bending line of a film trailer is formed on a slit, permitting the end of the film trailer to be inserted therein. In another preferred embodiment, a spool is provided with a resilient member or flap member for urging the inner turns of the roll of film toward its outer turns. The film trailer has increased bending rigidity by having an embossing treatment, applied thereto, or by attaching a skirt thereto.

摘要： In a photographic film cassette, light trapping fabric is provided on each of two inside surfaces of a film passage mouth which define a film passageway. Inner recesses, retracted from the inside surfaces, have the inner edges of the light trapping fabric attached thereto, with an adhesive agent enclosing the inner edges. In a preferred embodiment, tiny grooves are formed in the recesses to provide an increased attaching force, so that a considerable degree of attachment can be maintained. Further, the cassette has two shell halves which are joined together at respective edges. A projection is formed at a first one of those edges. The second edge has a contact projection thereon, for fitting in an inside recess of the first edge. Also, a crooked portion is formed along the juncture of the respective edges. As a result, no light will come through the spacing beside the film. A film leader is advanced through the film passageway by rotating the spool to an outside of the film passage mouth. When the film leader is forced to advance, it will never peel off the light trapping fabric, and so can be advanced reliably without being stopped by the light trapping fabric.
摘要翻译： 在摄影胶片暗盒中，在限定胶片通道的胶片通道口的两个内表面的每一个上设置有光捕获织物。 从内表面缩回的内凹部具有附着于其上的光捕获织物的内边缘，其中封闭内边缘的粘合剂。 在一个优选实施例中，在凹槽中形成微小的凹槽以提供增加的附着力，从而可以保持相当程度的附着。 此外，盒具有在相应边缘处连接在一起的两个半壳体。 在这些边缘中的第一个处形成突起。 第二边缘具有接触突起，用于装配在第一边缘的内部凹部中。 此外，沿着各个边缘的接合部形成弯曲部分。 结果，电影旁边的间距不会有光线。 通过将卷轴旋转到胶片通道口的外部，胶片引导件通过胶片通道前进。 当电影领导者被迫前进时，永远不会剥离光线收集的织物，因此可以在不被遮光织物阻挡的情况下可靠地前进。

摘要： A pair of teremps of a knitted structure are bonded to a blank of a shell plate of a film cartridge. A pair of teremps in continuous lengths is conveyed in the longitudinal direction thereof with the piled side of each of the teremps kept in contact with a locator member. The teremps in continuous lengths are bonded to opposite side edges of the blank and then cut to conform to the blank. Before they are brought into contact with the locator members, the teremps in continuous lengths are subjected to a process in which the pile is substantially uniformly oriented rearward at an angle with respect to the direction in which the teremps are conveyed.

摘要： Light shielding cloths excellent in light-shielding ability, and film drawing resistance are obtained by increasing the pile yarn density in accordance with a special formula, by passing pile yarns between the needle loop and the sinker loop of the ground fabric or by using a combination of regular yarn and special yarn. The contamination of the film by the thermobleeding of the dye is prevented by using a particular dye. The generation of static marks is also prevented by treating the light-shielding cloth comprising synthetic fiber with a special antistatic agent or treatment.

摘要： In a film cassette, a spool having a roll of film wound on it is rotatable within a cassette body, but the film leader of this film does not protrude from the cassette body. The roll of film is held between a pair of flanges of the spool or the film roll is pressed by a projecting member and a resilient member disposed on the inner wall of the cassette body. Thus the roll of film, when the spool is rotated, is also rotated together with it. As a result, the film leader is fed outside the cassette. In order to prevent light from entering the cassette from the film withdrawing slot, the film withdrawing slot is closed by a cover member and a mask. Also, by virture of a provision of a film passage extending within the cassette in a curved state or by mounting a projecting portion on the film leader, the interior of the cassette is masked.

摘要： A film cassette is provided with a film passage mouth to which pile fabrics are attached for trapping light. Pile threads of the pile fabrics are inclined flexibly in the film advancement direction to reduce resistance against film advancement. The leader of the film is formed in a triangular shape such that the film leader end passes the pile fabrics while gradually increasing the contact area with the fabric, thereby reducing resistance against film advancement.
