摘要： An exposure controlling device comprises, a controlling unit that controls a DC motor, a calculating unit that calculates a time period between a predetermined starting point and a point where a predetermined aperture area is obtained during the forward rotation of the DC motor, and a timer for counting the time period from the starting point. The controlling unit controls, at the time of an exposure, the DC motor to rotate reversely for a predetermined time period at a first step, to rotate forward to open shutter blades of a lens shutter at a second step and to rotate reversely to close the shutter blades at a third step.

摘要： A zoom lens camera includes a whole unit moving device to move a front lens group and a rear lens group together as a whole in an optical axis direction, and a relative moving means to vary a distance between the front lens group and the rear lens group. The whole unit moving means is driven during a zooming operation, and at least the whole unit moving means or the relative moving means is driven during a focusing operation to focus on a subject to be photographed.

摘要： A compact camera has a variable focal length photographing optical system, a multisegment photometric system that is separate from the photographing optical system, each segment outputting a brightness level, and a controller that determines an exposure value for exposing a film by using weighting coefficients to calculate a weighted average of the brightness levels outputted by the photometric system. The weighting coefficients vary according to the focal length of the photographing optical system.

摘要： A zoom lens for a camera having a between-the-lens shutter includes a motor for moving the lens along an optical axis in forward and rearward directions. A switch is operable by an operator to control operation of the motor for moving the lens from an initial position on the axis to a final stationary position that establishes the focal length of the lens. Control apparatus is responsive to the setting of the switch for operating the motor such that movement of the lens from its initial position to its final position always ends after the lens travels to its final position in a predetermined direction.

摘要： A lens shutter type of camera is disclosed in which a zoom lens is positioned in a lens block (1) which has a sector gear (15) rotatably associated with the lens block and with a rotatable cam ring (14). The cam ring and sector gear are rotatable in a substantially constant axial position. A movable finder optical assembly (8) and a movable strobe assembly (9) are movable in association with movement of the zoom lens. The zoom lens is movable between an extreme telephoto position and an extreme wide angle position, as well a into a fully collapsed lens position beyond the extreme wide angle position and a macro or close-up photographing position beyond the extreme telephoto position. When the camera is in its macro mode, a prism (P1) is inserted into the finder optical assembly to correct for parallax; the strobe assembly is moved to change its illumination angle; and an optical wedge (4e) is pivoted into the path between a light receiver (4) and a light emitter (3e). A single cam plate (53) is provided to move the finder assembly and the strobe assembly. The photographic aperture (22b) can be selectively closed by barrier plates (31a) when the zoom lens is moved into its fully collapsed position. A light intercepting assembly (210) is provided for preventing light from entering the photographic optical assembly via cam grooves (20 and 21). This intercepting assembly includes a flexible code plate (90) which surrounds a peripheral portion of the cam ring (14) and which provides positional information relating to the position of the zoom lens.
