摘要： A film cartridge, particularly associated with a camera, has a housing bounding a light-tight film roll chamber, and a mouth member arranged for passing a film therethrough and located outside the light-tight film roll chamber. The mouth member has a wall and at least one slot-shaped opening extending in a film transport direction and arranged so as to allow a film actuating member to engage therethrough a film received in the mouth member. Arresting means provided in the mouth member is engageable with an initial portion of the film and disengageable from the latter by camera-actuated means.

摘要： A film cassette for multi-exposure film strips has a body part with an inner compartment for a film strip and at least one opening for passage of the film strip therethrough between an initial position before exposure and a final position after exposure, and elements for preventing unintentional withdrawal of the film strip from the body part in at least one of these positions, the preventing elements arranged between the body part and the film strip. The preventing elements can be arranged so that they prevent unintentional withdrawal of the film strip in both positions. The preventing elements include a recess provided in one of the film strip and the body part, and a projection provided in the other of the film strip and the body part and engageable in the recess.

摘要： A photographic apparatus wherein the diaphragm is adjustable by a reciprocable selector which is provided with indicia denoting the scene brightness and the distance from the subject. The shutter is adjustable in dependency on the position of the selector, in dependency on the speed of film which is confined in the apparatus and in dependency on the condition of the apparatus, namely, whether the apparatus is set for the making of exposures in daylight or with flash. Cassettes which are used in the apparatus have markers denoting the film speed, and such markers influence the position of a reciprocable follower which can pivot a control lever loosely coupled to a shutter adjusting lever. The latter is pivotable by the control lever or by a motion transmitting lever whose position changes when a flashcube is attached to or detached from the housing of the apparatus.
摘要翻译： 一种照相装置，其中光阑可由往复式选择器调节，该往复式选择器设置有表示场景亮度和与被摄体距离的标记。 根据选择器的位置，快门是可调节的，这取决于限制在设备中的胶片的速度，并且依赖于设备的状态，即该设备是否被设置为在日光下进行曝光 或闪光灯。 在装置中使用的盒子具有表示胶片速度的标记，并且这些标记影响可往复运动的随动件的位置，该往复运动的随动件可以使松动地联接到快门调节杆的控制杆枢转。 后者可通过控制杆或运动传递杆枢转，运动传递杆的位置在闪光立体镜附接到设备的外壳或从设备的外壳上拆卸时发生变化。

摘要： A device for controlling the width of a slot of a diaphragm of a microfilm-reading-and-copying apparatus in which an enlarged microimage is projected by two inclined mirrors mounted on a movable carriage and via the slot of the diaphragm on a copying cylinder. The diaphragm is formed by two flaps of which one is stationary and another one is movable between a closed position to close the slot and a plurality of open positions to adjust the width of the slot. The drive of the movable flap is provided with a rotatable cam which is coupled to the movable carriage.
