    • A photographic film strip has a leader and a trailer, and is to be contained in a cassette having a rotatable spool. A first group of anchoring holes is formed in the trailer along a distal edge thereof, to be anchored on the spool. A second group of anchoring holes is formed at a position which is displaced from the first anchoring hole group toward the leader, and is utilized when the film strip is contained in a preserving cassette after development. In a preferred embodiment, a train of metering perforations are formed along a first lengthwise edge of the photographic film strip of regular intervals so as to be detected by a camera in order to detect positions of original frames. A plurality of take-up holes are formed in the leader, and adapted to being caught by a take-up spool of a camera. The take-up holes are out of alignment with the perforations. The camera has a cassette chamber. A fork is disposed in the cassette chamber over an exposure aperture, and is engaged with one spool end of the cassette on the side of the train of perforations, in order to rotate the spool. An area for recording data is formed on the photographic film strip along a second lengthwise edge which is opposite to the first edge. A magnetic recording head of the camera records data on to the recording area, and is disposed under the exposure aperture.
    • 照相胶片条具有引导件和拖车,并且被包含在具有可旋转卷轴的盒中。 拖车中的第一组锚定孔沿其远端边缘形成,以锚固在卷轴上。 第二组锚定孔形成在从第一锚固孔组朝向引导件移位的位置处,并且当显影后膜片被包含在保存盒中时被利用。 在一个优选实施例中,沿规则间隔的照相胶片条的第一纵向边缘形成一列计量穿孔,以便由照相机检测以便检测原始帧的位置。 在引导件中形成多个卷取孔,并且适于被相机的卷取卷轴卡住。 卷取孔与穿孔不对齐。 相机具有盒式室。 叉子在盒室中设置在曝光孔上,并且与打孔列的侧面上的盒的一个卷轴端接合,以便旋转卷轴。 用于记录数据的区域沿着与第一边缘相对的第二纵向边缘形成在照相胶片条上。 照相机的磁记录头将数据记录在记录区上,并设置在曝光孔下。

    • The rotation of a spool of a photographic film cassette in a film unwinding direction in a camera advances a film leader out of a cassette shell through a film passage mouth. An indicator window is formed on a surface of the cassette shell. A rotatable indicator wheel behind the indicator window carries an indication representing a degree of exposure of the photographic film, or unexposed, exposed, and numerals for frames at which the latest photograph was taken. A drive wheel is rotated in linkage with the spool for rotating the indicator wheel in order to move the indication into the indicator window. A clutch pin, which is connected with a pin receiver, transmits movement of the drive wheel to the indicator wheel when the spool rotates in the film unwinding direction. The indicator wheel is left separated from the drive wheel with the clutch pin disconnected from the pin receiver, when rotating the spool in a film rewinding direction. In a preferred embodiment, a toothed wheel, which carries an indicator for displaying the amount of film used, is rotated by the camera when advancing the photographic film. In another preferred embodiment, a heat-sensitive label is provided on the cassette shell for displaying the amount of film used in a visible manner by being heated according to the degree of film exposed in the camera.
    • 摄影胶片暗盒的卷筒在相机中的旋转方向使照相胶卷从胶卷盒的外壳通过胶片通道口。 在盒壳的表面上形成指示窗。 在指示窗后面的可旋转的指示轮携带指示摄影胶片暴露程度的指示,或未曝光的曝光,以及拍摄最新照片的框架的数字。 驱动轮与卷轴相联动地转动,以转动指示轮,以将指示移动到指示器窗口中。 与销接收器连接的离合器销在卷轴沿胶片退绕方向旋转时将驱动轮的运动传递到指示轮。 当旋转卷轴在胶片倒带方向时,指示轮与驱动轮分离,离合器销与销接收器断开。 在优选实施例中,携带用于显示所使用的胶卷量的指示器的齿轮在照相胶片前进时由照相机旋转。 在另一个优选实施例中,热敏标签设置在盒壳上,用于通过根据照相机中暴露的胶片的程度加热来显示以可见方式使用的胶片的量。

    • A developed photographic film is contained in a cartridge such that the leader end of the photographic film does not protrude from the cartridge, the film being wound on a spool. In one embodiment, the cartridge has a notch formed in the side of a port portion. The photographic film is pushed out of the cartridge by a sprocket accessed to this notch when extra prints are made. In another embodiment, two roll chambers are connected with each other through a bridge portion having an aperture for exposing a picture frame. A further embodiment includes a splice tape connected at one end to the spool, the photographic film being connected to the spool through this splice tape. These respective embodiments can also be used as a container for containing an unexposed photographic film.
    • 显影的照相胶片容纳在盒中,使得照相胶卷的前端不会从盒中突出,胶片被卷绕在卷轴上。 在一个实施例中,盒具有形成在端口部分侧面的凹口。 当进行额外的打印时,摄影胶片通过被连接到该凹口的链轮从盒中推出。 在另一个实施例中,两个辊室通过具有用于曝光相框的孔的桥接部彼此连接。 另一实施例包括在一端连接到卷轴的接合带,照相胶片通过该接合带连接到卷轴。 这些各个实施例也可以用作容纳未曝光的照相胶片的容器。
