ABSTRACT:
A miniature mirror reflex camera having a camera body carrying an objective lens at the front, and having at the rear means for holding a conventional film cassette of a known type made for miniature cameras. Arranged between the lens and the cassette is a sliding carrier movable in a direction perpendicular to the optical axis of the lens and at right angles to the direction of the travel of the film in the cassette. A reflex mirror is mounted in fixed position on this carrier, and below the mirror is a shutter. When the carrier is slid downwardly to a lower position, the reflex mirror intersects the optical axis and deflects the light rays coming in through the lens, upwardly to a viewing screen which is seen through an eyepiece and a pentaprism. In this position, the carrier effectively blocks passage of light rays rearwardly toward the film in the cassette. When the slidable carrier is moved upwardly toward the viewing screen, the shutter mounted on the slidable carrier is brought into alignment with the optical axis, and the opening of the shutter allows light to pass rearwardly from the lens through the open shutter to the film in the cassette, to make an exposure.
