Camera

A camera comprising:

• a release lever which is moved in one direction upon a shutter release operation;
• a movable control member urged into contact with said release lever in said one direction and movable in said one direction in accordance with the movement of said release lever;
• cam means arranged on said control member and having a first cam surface for defining a position of a photographing lens along an optical axis of the photographing lens, corresponding to a first object distance and a second cam surface for defining a position of the photographing lens along the optical axis, corresponding to a second object distance;
• a rack formed on said control member;
• a pinion meshing with said rack and rotating upon movement of said control member;
• a diaphragm plate which is fixed to said pinion and which is supported for rotation in association with rotation of said pinion;
• a plurality of diaphragm apertures formed on said diaphragm plate and successively alignable with a photographing aperture upon rotation of said diaphragm plate;
• a plurality of latch portions formed on an outer periphery of said diaphragm plate, each of said latch portions corresponding to a position of said diaphragm plate where one of said diaphragm apertures is aligned with the photographing aperture;
• means for stopping rotation of said diaphragm plate by engaging with one of said latch portions;
• means for detecting a distance to an object to be photographed and a brightness of the object;
• and
• means for controlling said stopping means so that said control member and said diaphragm plate stop in a position where said position of the photographing lens along the optical axis and one of said diaphragm apertures aligned with said photographing aperture correspond to the distance to the object and the brightness of the object detected by said detecting means, when the shutter release operation is executed.

A camera comprising:

• a lens, movable for focusing into a plurality of positions along an optical axis;
• a focusing guide cam, for moving said lens, and having a plurality of cam levels, each of said levels corresponding to a position of said lens;
• an aperture guide cam, for setting the size of an aperture through which a film is exposed, said aperture guide cam having a plurality of levels and a plurality of discrete positions, each discrete position of said aperture guide cam corresponding to a unique combination of a level of said aperture guide cam and a level of said focusing guide cam, such that the number of discrete aperture guide cam positions equals the number of unique combinations of focusing guide cam levels and aperture guide cam levels;
• a control member in which both of said aperture guide cam and said focusing guide cam are formed;
• and
• means for stopping said control member at one of a plurality of positions.

A camera comprising:

• a lens, movable for focusing into a plurality of positions;
• a focusing guide cam, for moving said lens, and having a plurality of cam levels, each of said levels corresponding to a position of said lens;
• a rotatable aperture mechanism, for setting the size of an aperture through which a film is exposed, said aperture mechanism having a plurality of settings and a plurality of angular positions corresponding to said settings, and rotatable in a full rotation for each level of said focusing guide cam;
• a control member that drives both said rotatable aperture mechanism and said focusing guide cam such that said rotatable aperture mechanism is fully rotated for every level of said focusing guide cam, a range of movement of said control member including all unique combinations of rotatable aperture mechanism angular positions and focusing guide cam levels;
• and
• means for stopping said control member at one of a plurality of positions.

A camera comprising:

• a lens, moveable for focusing into a plurality of positions along an optical axis;
• a focusing mechanism for moving said lens into each of said plurality of positions;
• an aperture mechanism for setting a size of an aperture through which a film is exposed;
• a control member mounted for movement in said camera;
• means for moving said control member in a single direction, upon a shutter release operation, for driving said focusing mechanism and said aperture mechanism to move said lens into one of said positions and to set a size of an aperture;
• means for stopping said control member at one of a plurality of positions for selecting a position of said lens along the optical axis and for selecting a size of an aperture through which a film is exposed from among a plurality of apertures.
