A novel gear arrangement is provided for coordinately performing two or more functions such as winding a film load within a camera, resetting the shutter thereof and setting the flash cube assembly therein. To effect these functions, an internal gear is provided having an internal annular area provided with gear teeth and an internal annular area free from gear teeth. Operatively connected to the internal gear are a plurality of planetary gears, each having an annular external area of gear teeth and an external annular area free of gear teeth, the respective gear teeth areas being in meshing engagement and the respective areas free of gear teeth being in facing relation. The internal gear is provided with a partially milled or corrugated exterior edge mounted through the camera housing. Rotatably connected to the planetary gears is a planetary carrier provided with at least one, and preferably two, sets of function driving gear teeth. Operatively connected to the planetary gears is a sun wheel provided with a set of gear teeth engaging said planetary gear teeth and a further set of function driving gear teeth. The sun wheel and planetary carrier are rotatably connected on a stationary shaft. As the milled edge of the internal gear is rotated, the function driving gear teeth are respectively displaced to effect functions in the camera.
A gear assembly for a camera adapted to coordinately perform at least two functions in said camera comprising an internal gear, a plurality of planetary gears in mesh with said internal gear, a planetary gear carrier, said plurality of planetary gears being rotatably mounted on said planetary gear carrier, a sun wheel operatively connected to said plurality of planetary gears, a stationary shaft, said planetary gear carrier and said sun wheel being rotatably mounted on said stationary shaft, means for rotating said internal gear, said planetary gear carrier being rotated about said stationary shaft as said internal gear is rotated, a first set of gear teeth on said planetary carrier for performing a first function, and a second set of gear teeth on said planetary carrier for performing a second function.
