Abstract: A camera includes a film cartridge mounting chamber which has a bottom film cartridge opening for loading a small film cartridge and a rear film cartridge opening for loading a large film cartridge, a back cover for closing the rear film cartridge opening, and a bottom cover for closing the bottom film cartridge opening. A lower spindle member is mounted on the bottom cover for holding the bottom of a cartridge spool of the loaded film cartridge. An upper spindle member is mounted on the top of the cartridge mounting chamber for holding a top of the cartridge spool of the loaded film cartridge. A first elastic clamping member is mounted inside the cartridge mounting chamber for applying an axial clamping force on the top of the loaded film cartridge. A second elastic clamping member is mounted inside the cartridge mounting chamber for applying a lateral clamping force on the periphery of the loaded film cartridge.

Abstract: A camera includes a cartridge mounting chamber, a film take-up chamber, a photographing unit provided between the cartridge mounting chamber and the film take-up chamber. The photographing unit includes a lens housing having a front housing portion holding a lens and a rear housing portion defining a diverging light passage, and a screen adjustment frame having an opening and a frame part confining the opening. The frame part is movable rearward and forward along a direction of the light passing through the diverging light passage for confining the light to pass through the opening. The camera has a device for moving the screen adjustment frame responsive to loading of a film cartridge in the cartridge mounting chamber.

Abstract: A camera has a cartridge mounting chamber which receives a film cartridge with a cartridge spool, a film exit, and a light-intercepting door. The camera includes a spindle for holding the cartridge spool, a drive mechanism for rotating the spindle in a first direction to feed the film during the photographing operation and in a second direction to wind up the film after completing the photographing operation. The drive mechanism includes a sun gear, a first planetary gear and a second planetary gear engaging the sun gear, and a planetary carrier holding the first and second planetary gears and disposed coaxially with the sun gear. The sun gear is rotatable in two directions for turning the planetary carrier between a first position, in which the first planetary gear drives the spindle in the first direction, and a second position in which the second planetary gear drives the spindle in the second direction.
