AERIAL CAMERA Russian patent published in 2006 - IPC G03B37/00 

FIELD: optical instrument engineering; aerial photography.

SUBSTANCE: aerial camera can be used for making framing cameras. Aerial camera has objective, photo shutter, aerial photo film disposed in film-pulling mechanism. All the members are connected in series. Film-pulling mechanism has receiving penal, measurement shaft, balancing table and feeding penal; all the members are disposed in series. Balancing table is disposed onto optical axis behind aerial photo film. Measurement shaft and balancing table together with compensation drive form image shift compensation mechanism. Case is mounted for movement along optical axis onto supports. One support is made in form of screw cinematic pair. Focusing mechanism has focusing drive. Screw cinematic pair is cinematically connected with case of compensation mechanism at the side of balancing table. Compensation mechanism's case is spring loaded by resilient member at the other side. Screw cinematic pair is made in form of differential screw. Screw is additionally provided with thread having smaller pitch. Onto thread the bushing is mounted for translation. Bushing is cinematically connected with case of compensation mechanism and it is spring loaded by resilient member.

EFFECT: improved precision of operation of focusing mechanism; improved reliability of operation of aerial camera; improved quality of photos.
