スリットから臨出させている。2. Description of the Related Art A conventional film for photography is such that an unexposed film is wound around a core shaft and housed in a cylindrical case, and both ends of the core shaft are inserted through holes in both end cover plates of the case. It is exposed and the tip of the film is exposed from the slit on the peripheral surface of the case.
【０００３】ケースごとフィルムをカメラにセットした
とき、カメラのフィルム巻戻し用爪が、ケースの上下の
穴の何れか一方に嵌まり、穴奥の掛かり片に係合する。When the film together with the case is set in the camera, the film rewinding claw of the camera fits into one of the upper and lower holes of the case and engages with the hanging piece at the back of the hole.

されてあれば、フィルムが使用済み、即ち、露光してい
ることが外観から判断できる。After photographing, the film is rewound into the case by rotating the rewinding claw by manual lever operation or a motor, and the film is taken out together with the case. At this time, the case is extended to the leading edge of the film. If it is rewound inside, it can be judged from the appearance that the film is used, that is, exposed.

了となるものがある。However, in the case of the manual winding mechanism, the rewinding can be completed with the ears of the film protruding from the case by adjusting the winding lever, and in the case of the camera with the automatic winding device. , Depending on the model, rewinding may be completed with the tip of the film exposed from the case.
【０００６】撮影済のフィルムでも、フィルムの先端耳

して放置したままにすると、フィルムが使用済が否かが
判らなくなる。[0006] Even if a film has been photographed and the front end of the film is protruding from the case, it is impossible to know whether the film is used or not if it is taken out of the camera and left as it is.
【０００７】又、何本ものフィルムを使用して撮影する
場合、未使用のフィルムと撮影済のフィルムが混じって
しまい、やはり使用済と未使用の区別ができなくなる虞

割合は、信じられられぬほど多いのである。Further, when shooting with many films, there is a possibility that unused film and film that have been shot are mixed, and it is still impossible to distinguish used film from unused film. The proportion of film that is brought into the lab unworn is incredibly high.

ことを防止できる。Generally, once the film is set in the camera, the film is never taken out without pressing the shutter, and therefore, the thin sheets above and below the core shaft (2) are not taken out.
(3) If one of the thin sheets (3) is broken,
The film in the case can be judged to be a film that has already been photographed. As a result, it is possible to prevent the unphotographed film, that is, the unexposed film, from being brought to the developing station and wasting the film and the developing cost.

カメラを選ばない。When the cased film (4) is set in the camera, however, the film rewinding claw (5) pierces the thin sheet (3) blocking the upper and lower holes of the core shaft (2). Depending on the model of the camera, the film rewinding claw (5) engages the hole (22) of the core shaft (2) from the top or the core shaft from the bottom.
Some of them engage with the hole (23) of (2), but since the thin sheets (3) and (3) are attached to the holes (22) and (23) at both ends of the core shaft (2),
Choose any camera.
