Abstract: A projector having illumination and optical devices for projecting one or more images having a rotating magazine having a plurality of pockets disposed about its periphery for holding multiple slide film cartridges. The pockets loosely retain and orient the cartridges within the magazine in a manner such that a film strip contained therein can be advanced across a film gate between the illumination and optical devices once the magazine has rotated the pocket containing the cartridge to a projecting station.

Abstract: A recording apparatus comprising a magazine for storing a recording material, and a sensor for detecting a quantity of the recording material stored in the magazine. The magazine is movable between an inward position for supplying the recording material to a recording station and a position protruding from the apparatus body. A magazine moving device is provided which, in response to the sensor, moves the magazine from the inward position to the position protruding from the apparatus body.

Abstract: A roll film driving device is capable of accommodating different film cartridges housing reels of different coupling methods to a driving shaft and forwarding and reversing the reeled film by coupling the reel with the driving shaft. The driving shaft is provided with different coupling members respectively adapted to different reels of the film cartridges, wherein each coupling member is bound to the driving shaft in the rotating direction but is axially movable between a coupled position and a noncoupled position, and a coupling member matching the reel of the loaded cartridge is selected to make such movement.

Abstract: In a roll film carrier for a reader or a reader printer according to the invention, a first type film cassette and a second type film cassette being different from each other in connection system between a drive source and an enclosing reel within a cartridge can be installed detachably. The roll film carrier comprises a first reel drive shaft to drive an enlosing reel within a first type film cartridge and a second type reel drive shaft to drive an enclosing reel within a second type film cartridge, and selectively connects the reel drive shafts corresponding to type of the cartridge thereby cartridges of different types can be used.

Abstract: A motion picture projection apparatus capable of selective use of two types of films with an open reel assembly and a film cartridge having mounted therein a pressure plate associated with a reflecting mirror. The apparatus is provided with a displaceable member carrying a pressure plate associated with a light reflecting element for use with a film strip fed from the open reel assembly. The displaceable member is arranged in the projection station of the apparatus to be displaced to a projection position where the film of open reel type is in alignment with the optical axis of the projection system and to an idle position where the film of open reel type is out of alignment with the projection system in automatic response to a removal and an insertion, respectively, of the film cartridge from and into the projection position. This is a continuation of application Ser. No. 472,416 filed May 22, 1974, now abandoned.
