    Abstract: An indicator provided within a view finder for a single lens reflex camera, includes a pentagonal prism having a roof reflection surface that reflects light emitted from a focusing plate which is located at a position optically equivalent to an imaging plane of a photographic lens of the single lens reflex camera, and a third reflection surface which reflects the light reflected by the roof reflection surface toward an eyepiece, wherein the third reflection surface includes a semitransparent surface. The indicator includes an auxiliary prism adhered to the semitransparent surface; an indicator plate including an information mask; and an illumination light source which emits light through the information mask of the indicator plate, in that order from the opposite side of the auxiliary prism with respect to the third reflection surface thereof; and a diopter correcting lens, which makes the position of the indicator plate optically equivalent to the position of the focusing plate, provided between the auxiliary prism and the indicator plate.

    Abstract: To prevent temporary reduction of battery voltage when driving a shutter, an exposure control drive apparatus is provided with a boosting circuit for boosting a voltage of the battery and outputting a boosted voltage. A capacitor is charged by the boosted voltage for driving an actuator of an exposure control mechanism. A detecting circuit detects a current flowing in the boosting circuit and a control circuit controls operation of the boosting circuit in accordance with a magnitude of the detected value so that the boosting circuit is prevented from boosting the battery voltage when the detected current exceeds a predetermined level and is permitted to boost the battery voltage when the detected current is below the predetermined level. In this manner, the current flowing from the battery is prevented from exceeding a maximum level.

    Abstract: A camera includes a finder for enabling an image which is shot on a film to be monitor-displayed by branching a portion of a light beam (image) imaged by a picture-taking lens system, by an up/down movable pellicle mirror comprised of a half mirror, to let the image be received on a image pick-up device. In this camera, a pupil-dividing LCD is arranged in front of the image pick-up device to impart a phase difference to the light beam imaged by the picture-taking lens system to obtain corresponding image data. By doing so, phase difference AF control is carried out. The image pick-up device has both the function of monitoring a pick-up image and the function of detecting a just-in-focus state.

    Abstract: A compact and inexpensive camera is provided, in which an illuminating unit for illuminating finder indices is arranged so as not to interfere with a quick-return reflecting mirror nor interfere with a built-in electronic flash device. A finder optical system has a focusing screen provided therein, which has at least one finder index formed thereon. A reflecting mirror is disposed to make upward and downward movements in a flipping motion area between a reflecting position where the reflecting mirror reflects and guides a photographic light beam to the finder optical system, and a shooting position where the reflecting mirror recedes from a photographic light path. An illuminating unit illuminates the at least one finder index formed on the focusing screen to display the at least one finder index in superposition on a finder image formed by the photographic light beam. The illuminating unit is arranged at a lateral side of the flipping motion area of the reflecting mirror. Illuminating light from the illuminating unit is reflected by the reflecting mirror located in the reflecting position to illuminate the at least one finder index.
