A micro-reader which comprises a generally rectangular box-like, flattened casing a slide frame slidably supported by the casing for movement between retracted and extended positions, a light-permeable screen mounted on and supported by the casing for movement between folded and erected positions, and a reflective mirror member carried by the slide frame for movement between laid-down and upright positions. When the micro-reader is not in use with the slide frame, the screen and the mirror member being held in the retracted, folded and laid-down positions, respectively, the screen and the mirror member constitute cover members for covering the top and bottom of a space between the casing and the slide frame, but when the micro-reader is in use with the slide frame, the screen and the mirror member held in the extended, erected and upright positions, respectively, the mirror member confronts the screen at a predetermined angle while lying in a plane different from the plane which is occupied by the mirror member when in the laid-down position.

Micro-reader

A microform-reader which comprises a generally rectangular box-like, flattened casing a slide frame slidably supported by the casing for movement between retracted and extended positions, a light-permeable screen mounted on and supported by the casing for movement between folded and erected positions, and a reflective mirror member carried by the slide frame for movement between laid-down and upright positions. When the microform-reader is not in use with the slide frame, the screen and the mirror member being held in the retracted, folded and laid-down positions, respectively, the screen and the mirror member constitute cover members for covering the top and bottom of a space between the casing and the slide frame, but when the microform-reader is in use with the slide frame, the screen and the mirror member held in the extended, erected and upright positions, respectively, the mirror member confronts the screen at a predetermined angle while lying in a plane different from the plane which is occupied by the mirror member when in the laid-down position. The microform-reader also comprises a foldable light-shielding hood for intercepting the entry of external light into the optical path particularly between the reflecting mirror and the screen.

Microform-reader

A photographic camera comprising a principal lens assembly and a converter lens assembly for providing a focal length different from that of the principal lens assembly when used. The converter lens assembly is carried by an intermediate barrel for the support of the principal lens assembly through a lens mount such that the converter assembly can move together with the principal lens assembly. A switching mechanism is also used for selectively bringing the converter lens assembly into and out of alignment with the optical axis of the principal lens assembly.

Photographic camera with built-in optical converter

A photographic camera comprising a principal objective lens assembly including an objective lens mount and a focus adjusting ring carried by the camera body through a fixed barrel for rotation through first and second predetermined focusing angle. The focus adjusting ring is operatively coupled to the objective lens mount such that rotation of the focus adjusting ring results in linear movement of the objective lens mount in an axial direction parallel to the optical axis of the objective lens. An optical converter lens is supported for movement between an inoperative position, in which the converter lens is out of alignment with the optical axis of the objective lens, and an operative position in which the converter lens is aligned with the optical axis of the objective lens. This optical converter is brought into the operative position when the focus adjusting ring is rotatable through the second focusing angle while it is brought into the inoperative position when the focus adjusting ring is rotatable through the first focusing angle.

Data recording camera permitting prior confirmation that data recorded simultaneously with taking of a photograph is accurate and is in a correct position relative to a photographed scene. A data specification means which is provided inside the camera and is movable to different settings by externally actuable means comprises one or more rotatable disks, each of which has identical data marked on diametrically opposite peripheral portions thereof. For any given setting, a data value on one side of a disk is in position to produce a latent image on film material, and the identical value on the opposite side of the disk is so positioned that an image thereof may be projected to the camera viewfinder where it is viewable by the photographer.
