摘要： The housing of a rechargeable magazine for 8-millimeter motion picture film has two chambers one of which contains unexposed and the other of which contains exposed film. The exposed film is convoluted on a core which is rotatable in the other chamber and is coaxial with a stationary core for unexposed film. The rotary core carries an elastic pawl which normally engages one of several internal teeth in an annular internal sleeve of the housing to prevent rotation of such core in a direction to pay out the film. The rotary core further comprises a flange which overlies the pawl and has an opening through which the pawl can be reached by a tool in order to allow for deformation of the pawl so that the rotary core can be rotated in a direction to pay out exposed film. The rotary core defines with the sleeve a labyrinth seal and the opening is normally sealed by an opaque foil of elastomeric material which can be flexed by the tool in order to move a projection of the tool into engagement with a complementary projection on the elastic pawl. The housing has a removable cover which affords access to the chamber for unexposed film so that the latter chamber can be loaded with fresh film upon completed exposure of the previously inserted film. The elastic pawl can be broken off the rotary core when the latter is forcibly turned in a direction to pay out the film so that the magazine can be used in cameras which are designed to make exposures with lap dissolve, i.e., wherein the film frames which were exposed with fade-out effect must be transported rearwardly prior to renewed exposure but with fade-in effect.

摘要： A magazine for motion-picture film which comprises a casing having first and second chambers for convoluted exposed and unexposed film, a core member rotatable in the first chamber and coaxial with unexposed film in the second chamber to respectively collect and pay out exposed film during rotation in first and second directions, and a blocking device including a sleeve movable axially of but rotatable with the core member and a disk mounted in the casing. A spring biases the sleeve into engagement with the disk to hold the core member against rotation in the second direction. A rotary output member of a drive in the camera moves the sleeve axially and away from engagement with the disk when the magazine is properly attached to the camera whereby the core member can be rotated in either direction as long as the magazine remains attached to the camera.
