A device for the removal of sheet-like films from an X-ray film cassette or a film magazine by means of at least one sucker which has a suction lip with a frustoconical inner surface by which a front edge of a film is lifted from the stack. The suction lip has at the inner surface in the proximity of the mouth of the suction conduit a flat projection extended towards the film being lifted but is spaced therefrom.

The reproducing apparatus, such as a motion-picture film projector, stops recording medium transport in response to interrupt-transport frame markings on the recording medium and reproduces the thusly marked image frames as still images. Interrupt-transport frame markings are provided at the terminal frame of each motion-picture scene on the recording medium, or at each still-shot image frame on the recording medium, or both. The user of the reproducing apparatus can select automatic reproduction of motion-picture scenes interspersed with automatic still reproduction of still shots, and can additionally select automatic still reproduction of the terminal frame of each motion-picture scene.

A film supplying magazine which receives a pack of film sheets, covered with a light-tight sheathing and is insertable into a device which removes from said pack individual film sheets, comprises a box receiving a film pack, and a cover for closing the box. The sheathing has a winding flap while the magazine has an externally operated rotatable winding shaft to which the flap of the sheathing is connected so that the flap together with the sheathing is pulled off the pack and wound on the shaft when the latter is rotated. Velcro tapes are provided at the free end of the flap and at a portion of the winding shaft, which ensure an automatic connection between the flap and the shaft.

In a device for unloading X-ray film cassette a nozzle is provided, positioned at a front side of the cassette to be unloaded, for blowing air into a gap between a slightly open lid and the remaining part of the cassette. The nozzle is switched on for short intervals to ensure blow air stream which generate vacuum under the film stuck to the lid to pull the film back towards the bottom of the cassette so that a reliable separation of the film by a sucker is ensured.

A supply magazine for insertion in an arrangement for removing individual sheet films, for example X-ray sheet films, arranged in a stack in a light-tight wrapping, comprises a cover, a box which is at least partially open and is closable by the cover, and being formed for accommodating a stack located in a wrapping, a winding device provided with a winding shaft which is driven from outside and formed for suspending and winding a winding flap of the wrapping together with the latter after closing of the box, and an indicating device including a movable sensing member which abuts with spring biasing against the winding shaft in the region of the winding flap, an observation opening formed in a part of the box which supports the winding shaft and arranged so that the sensing member is visible through the observation window, and a light sealing provided between the winding shaft and the observation window.

A cassette for a stack of superimposed sheets of X-ray film has a bottom wall, four sidewalls disposed at the upper side of and defining with the bottom wall a rectangular or square chamber for at least one stack of sheets, and a cover which is pivotally connected to one of the sidewalls and is movable between an open position to afford access to the chamber and a closed position in which it cooperates with the sidewalls to prevent penetration of light into the chamber. The top surface of at least one sidewall is provided with one or more markers (e.g., in the form of a row of triangular indicia) made of or containing a material which permits ready visual detection of the marker in a darkroom whereby a person looking at the marker can ascertain at a glance whether or not one or more uppermost sheets of a stack in the chamber are misaligned so that they overlie the top surface or surfaces of one or more sidewalls and must be reoriented prior to pivoting of the cover to closed position. Such pivoting of the cover to closed position could result in damage to the misaligned sheet or sheets.

A supply magazine has a drawer-shaped, upwardly open box for introducing a sheet film stack in a light-tight envelope and for withdrawing individual sheet films after removal of the envelope, a cover part movable relative to the box, a unit for winding the envelope in a closed condition of the magazine. The cover part is formed as a flat parallelepiped which is open at its front small side and such that the box which is open at its upper side can be moved in and out of the cover part, a locking mechanism operates for locking the cover part and the box when the box is moved in. A lockable and swingable flap cover is provided on a flat side of the cover part corresponding to the upper side of the box so that when the box is moved in the cover part a sheet film stack can be inserted in the box through the flap cover.
