Abstract: In the disclosed finder, a half transparent surface positioned behind a photographic lens splits off part of the light passing through the photographic lens to a first image plane at a position equivalent to a focal plane of the photographic lens. At least two lens components refocus light from the first image plane onto a second image plane conjugate to the first one. An image on the second plane is observed through an eyepiece. An even number of reflective surfaces, but not less than four, including the half transparent surface, are arranged in an optical path from the photographic lens to the eyepiece and at least one of these reflective surfaces lies between the two lens components. A decrease in the physical length of the finder and an increase in the image magnification are achieved.

Abstract: An apparatus for mounting a camera to a supporting structure, such as an automobile window, and permitting instantaneous reorientation of the camera's photographic frame between horizontal and vertical formats. A camera is attached to a mounting arm which is pivotally interposed between two frame members. The frame members are fixed in parallel spaced relation by a spacer therebetween, the spacer also serving to limit rotation of the mounting arm to a 90-degree arc. The camera is attached to the mounting arm in such a location with respect to the pivot point of the mounting arm so as to impart a movement to the mounting arm which urges the mounting arm against the spacer at either extremity of the arc. The frame members and the spacer define two recessed channels to closely receive the mounting arm at either extremity of the arc and stabilize the mounting arm and camera.

Abstract: A motor driven camera for winding and rewinding film by an electric motor includes a mechanism for detecting the end of a length of loaded film to produce an actuating signal. An automatic changeover mechanism responds to the actuating signal by changing the state of a film transport mechanism in the camera from a film winding operating mode to a film rewinding operating mode. The automatic changeover mechanism is arranged to be operated in response to closing of the back cover of the camera. Accordingly, the transition from the winding to the rewinding operating modes is controlled automatically.

Abstract: In the disclosed viewfinder for a camera, the light passing through the photographic lens is reflected an even number of times, focused on a first image plane at a position equivalent to a prescribed focal plane of the photographic lens, and then further reflected from the roof reflection surfaces of a roof type prism to pass through an eyepiece, thereby the image on the first image plane can be observed through the eyepiece.

Abstract: In a photographic camera, closing sliding movement of a camera back moves a film-engaging member mounted on the back to thread a film leader from a film cartridge to a take-up drum. At the completion of closing movement of the camera back, a separator disengages the film-engaging member from the leader. This permits the take-up drum to advance an unexposed section of the film from the cartridge and to wind an exposed section of the film onto the drum, each time the drum is rotated. A rewind member is provided for rewinding the exposed film into the cartridge by rotating a film spool connected in the cartridge to an end portion of the film. An actuator on the camera back moves the rewind member into engagement with the spool in response to closing movement of the camera back. The engagement secures the cartridge in place during advancement of the film to the take-up drum, and permits the rewind member to rotate the spool to rewind the film into the cartridge.

Abstract: A disc camera drive mechanism has a manually movable film advance member reciprocable between a rest and an actuated position, a shutter and a manually movable shutter release element. Drive means actuated by the film advance member on its movement to actuated position rotates the disc film and activates spring means. Spring retainer means retains the spring means in activated position. Release of the spring means operates the shutter on actuation of the shutter release element. A spring urged film detent element is actuated by the drive means, and on release of the spring means the detent element is urged against the film during the latter part of its advance so as to engage a film detent opening when the latter comes into register. The detent element is withdrawn from the opening after the shutter is operated. A stop movable with the detent element may block shutter movement when the detent element is in its withdrawn position.

Abstract: The invention relates to an electromagnetically operated leaf shutter particularly for use in photographic cameras installed in microscopes in which a rotatable annular armature including a light passage is provided with an even number of poles radially extending to an annular field ring being secured into a tubular shutter housing. The annular field ring is provided with an even number of pole-shoes extending towards the armature poles. The armature and the field ring are made of "soft magnetic" material. The geometry of the pole-shoes and the adjacent respective poles is so that an optimum of magnetic force is exerted upon the armature when the electromagnetic coils which surround the pole-shoes are energized, and, hence, a rotation of the armature is effected. The armature is provided with means to operate the blades of the shutter in order to open the light passage.
