FIELD: air photography.
SUBSTANCE: when air photographic camera is switched to "photographing" position the photo-lock operates and frame is exposed through objective at simultaneous compensation of image shift. Expose frame is rewound by drives of receiving and supplying coils. Coils are disposed inside containers. Signal coming from potentiometer is introduced into drive control circuit. Potentiometer traces changes in radiuses of bobbins of receiving and supplying coils. Added control signals enters drives; amount of photo-tape in containers is taken into account. While exposed frame is subject to re-winding, lever turns as well as axis connected with lever by means of half-cylinders. Rotation is supplied to potentiometer through cogwheels. Simultaneously the motion transmits to cogwheels and to reading mechanism. Reading mechanism interacts with fixative mechanism. After exposed frame is rewound, photo-lock is cocked. Film transport sets mechanism of air photographic camera to initial position for making photo of the next image.
EFFECT: improved precision; improved reliability; higher quality of photos.
