ABSTRACT:
A camera using a film cartridge having a shaft for winding a film and intercepting light, includes: a cartridge chamber for accommodating the film cartridge; a driving unit; a driving source for generating force for driving the driving unit; a transmitting device; and a limiting device. The driving member engages the shaft of the film cartridge accommodated in the cartridge chamber, and rotates the shaft in the film unwinding direction to remove the film from the film cartridge. The transmitting device is provided between the driving source and the driving unit, and transmits the force generated by the driving source to the driving unit. The limiting device is provided in the transmitting device, and limits the force to be transmitted to the driving unit so as to feed the film in the film unwinding direction.
