Abstract
A camera includes a motor, a planet gear mechanism having a planet gear to be revolved or rotated by the motor, a film wind mechanism provided on a revolution orbit of the planet gear and meshed with and driven by the planet gear upon forward rotation of the motor to perform film winding, a film rewind mechanism provided on the revolution orbit of the planet gear and meshed with and driven by the planet gear upon reverse rotation of the motor to perform film rewinding, a focal point switching mechanism provided on the revolution orbit of the planet gear and meshed with and driven by the planet gear upon reverse rotation of the motor to switch a focal length of a photographic lens, and a selecting mechanism for selectively causing the planet gear to mesh with the film rewind mechanism or the focal point switching mechanism upon reverse rotation of the motor.
