摘要： A photographic apparatus wherein the diaphragm is adjustable by a reciprocable selector which is provided with indicia denoting the scene brightness and the distance from the subject. The shutter is adjustable in dependency on the position of the selector, in dependency on the speed of film which is confined in the apparatus and in dependency on the condition of the apparatus, namely, whether the apparatus is set for the making of exposures in daylight or with flash. Cassettes which are used in the apparatus have markers denoting the film speed, and such markers influence the position of a reciprocable follower which can pivot a control lever loosely coupled to a shutter adjusting lever. The latter is pivotable by the control lever or by a motion transmitting lever whose position changes when a flashcube is attached to or detached from the housing of the apparatus.

摘要： A device for controlling the width of a slot of a diaphragm of a microfilm-reading-and-copying apparatus in which an enlarged microimage is projected by two inclined mirrors mounted on a movable carriage and via the slot of the diaphragm on a copying cylinder. The diaphragm is formed by two flaps of which one is stationary and another one is movable between a closed position to close the slot and a plurality of open positions to adjust the width of the slot. The drive of the movable flap is provided with a rotatable cam which is coupled to the movable carriage.

摘要： The user of the camera moves an input component to supply film-transport force. A rotary transmission transmits film-transport force fo the input component to the film in the camera, and includes first and second output components. When the input component is moved, the first output component is arrested and the second non-arrested, and then the second output component is arrested and the first non-arrested. A locking structure moves from a locking position arresting the first output component and an unlocking position releasing the first output component. A sensing mechanism responds to film frame advancement by entering into a film perforation, causing the locking structure to move to the unlocking position and causing the second output component to become arrested by the resistance of the film to transport. The transmission includes a gear driven by the input component and driving the second output component and displaceable mounting member mounting the gear for both rotation and displacement. The displaceable mounting member constitutes the first output component of the transmission.
