ABSTRACT:
The invention refers to a device (30) for opening and closing a film cartridge closure (311) of a film cartridge (31), with which opening and closing of the film cartridge closure can be made possible independently of active drive or power transfer elements, such as a motor and linkage. According to the present invention, this is achieved in that a stationary film cartridge holder has a shaft, for opening and closing the film cartridge closure (311), which is mounted so as to displace through a displacement travel (L) in the axial direction; and means (4, 5) are provided with which the shaft (1) is positively guided in such a way that a displacement through the displacement travel (L) results in a rotation of the shaft through 90 degrees.
