The camera includes a cartridge chamber with accommodates the film cartridge, an engaging member which is rotatably provided in the cartridge chamber and engageable with the light blocking lid when the film cartridge is place in the cartridge chamber, and an actuator which actuates the engaging member to open and close the light blocking lid. The actuator includes a motor which generates a driving force, a crank member driven by the motor, and a link member which operatively connects the crank member with the engaging member. A fork is provided in the cartridge chamber which is engageable with a spool provided in the film cartridge, and a film take-up chamber is provided with a take-up spool for taking up the film. A transmission mechanism transmits a driving force from the motor to the crank member, the take-up spool and the fork, and has a first transmission route transmitting the driving force to the crank member, a second transmission route transmitting the driving force to the take-up spool to wind the film, and a third transmission route transmitting the driving force to the fork to rewind the film. A changer changes over the first, second and third transmission routes.
