Abstract
A camera has a spool drive shaft disposed to project from an inside of a cassette holder chamber, connected with a spool of a photo film cassette coaxially, to feed a photo film from a cassette, and to wind the photo film back into the cassette. A sun and planet gear mechanism includes a sun gear for rotating in a first direction in response to forward rotation in a first direction in response to forward rotation of a motor, and for rotating in a second direction in response to the backward rotation of the motor. A feeding planet gear and returning planet gear are meshed with the sun gear. Two feeding transmission gears are meshed with the feeding planet gear for rotating in the first direction in response to forward rotation. A returning transmission gear is meshed with the returning planet gear for rotating in the first direction in response to backward rotation, to cause a spool drive shaft to rotate in the winding direction. The two feeding transmission gears and returning transmission gear are disposed coaxially with one another.
