A camera includes: a lens barrel holding a zoom lens; a zoom viewfinder optical system having a variable magnification lens to be moved in the optical axis direction; a cam pin integrally provided on the variable magnification lens; and a cam member to move the variable magnification lens being interlocked with the movement of the lens barrel. The cam member has the cam surface provided with a protruded portion which comes into contact with only a portion of a side wall of the cam pin.

Camera equipped with cam member and molding die for producing the cam member

A zoom camera being capable of changing a distance measuring direction to measure an object distance, and more particularly a camera which indicates the distance measuring direction overlapped on an object image in a view finder display. An object image is displayed in a finder display through an optical system, thereby the magnification of the object image in the view finder changes in accordance with a zooming of the camera. An indicator array is arranged on the view finder display, and the distance measuring direction is indicated by an activation of an indicator element of the indicator array located at a corresponding position to an object position in the distance measuring direction. For the purpose of coordinating with the change of magnification of the view image, the corresponding position is determined based on the focal length information obtained by a focal length detector in addition to distance measuring direction information and distance information, each obtained by each of a direction detector and a distance detector.

An automatic focusing device comprises a motor operated by a range signal, a lens moving system in which a lens is moved by the motor, a clutch for engaging and disengaging the motor from the lens moving system and a power switch for the motor. A switchover member is provided which is selectively settable to a manual mode, and auto-focus mode and a focus-lock mode. The modes are changed over by a combination of an engagement or disengagement of the clutch by the switchover member and a switchover of the power switch (between ON and OFF) by the switchover member.

Automatic focusing device

A foldable camera for self-developing film comprises a base housing and a movable member pivotable between a closed position integrated with the housing and an open, elevated position above the housing. The movable member is mounted to a supporting member which is pivotally coupled to the housing at the end opposite from the film exit end of the housing. An objective lens and a reflex mirror are fixedly mounted to the movable member in fixed relationship to each other such that they are in the proper positions for film exposure when the movable member is pivotted to the elevated position.
