ABSTRACT:
A camera having a lens barrel and a compartment for holding one of a spool and a cartridge. A motor in the camera is coupled to a reduction gear train which transmits a drive force of the motor to the lens barrel. A rotary shaft, positioned between the compartment and the lens barrel, is geared to and branches from the reduction gear train so as to receive a drive force from the reduction gear train. A zoom finder device, positioned between the compartment and the lens barrel is driven by the rotary shaft. This arrangement allows the motor to transmit a drive force to a driven device placed adjacent to a drive source, without making the drive device large, and without unnecessarily increasing the number of required components.
