A camera has a movable lens barrel that is stowed in a camera body while the camera is inactive, and is protruded from the camera body to a near range focusing position or a far range focusing position by rotating a drive ring in one direction. The movable barrel returns to the stowed position by rotating the drive ring further in the same direction, because of a cam mechanism interconnecting the drive ring with the movable barrel. To rotate the drive ring, a rotational power of a motor in a first direction is transmitted to the drive ring through a clutch mechanism. The clutch mechanism is switched over according to the rotational direction of the motor and transmits a rotational power of the motor in a second direction to another mechanism. A controller controls driving the motor in response to signals entered through manually operated members, including a power switch, a shutter button and a zone selector, with reference to detection signals from a barrel position detector.

Camera with motor-driven lens barrel

There is disclosed a camera in which two lens covers are enabled by a spring force of an open and close spring in a direction that the two lens covers are closed.

Camera

A field frame for use with a finder which provides arbitrary or stepwise switches of an aspect ratio of the finder. The field frame is made up of a standard field frame, a first L-shaped field switch frame having a dowel pin and two elongated holes, and a second L-shaped field switch frame having a dowel pin and two elongated holes. These two L-shaped field switch frames are piled up one on top of the other in such a manner that dowel pins standing on the main body of the standard field frame fit into the laminated elongated holes of the L-shaped field switch frames. A driving wheel having engaging cutouts is also laminated on the L-shaped field switch frames so that the engaging cutouts can engage with the dowel pins of the field switch frames. The driving wheel is also provided with a lever. The clockwise rotation of the driving wheel causes the field switch frames to conceal the right and left edges of the standard field frame, whilst the counterclockwise rotation of the driving wheel causes the field switch frames to conceal the upper and lower edges of the standard field frame.

Field frame for finder

A film transporting device transports photographic film by driving a spool of a cartridge and a takeup spool which takes up the photographic film supplied from the cartridge by means of a single motor which is rotatable forward and backward. Unidirectional rotational driving force is transmitted from the motor to the spool and the takeup spool via one planet gear mechanism, and the photographic film is supplied from the cartridge, and then the takeup spool takes up the photographic film. The rotational driving force from the motor in the other direction is transmitted to the spool via the planet gear mechanism, and the photographic film is rewound into the cartridge. When the takeup spool takes up the photographic film, a one way clutch can absorb a difference of the transport speed between the takeup spool and the spool of the cartridge.

These two L-shaped field switch frames are piled up one on top of the other in such a manner that dowel pins standing on the main body of the standard field frame fit into the superposed elongated holes of the L-shaped field switch frames. A driving wheel having engaging cutouts is also superposed on the L-shaped field switch frames so that the engaging cutouts can engage with the dowel pins of the field switch frames. The driving wheel is also provided with a lever. The clockwise rotation of the driving wheel causes the field switch frames to conceal the right and left edges of the standard field frame, whilst the counterclockwise rotation of the driving wheel causes the field switch frames to conceal the upper and lower edges of the standard field frame.
