Title (EN) DEVICE FOR A PHOTOGRAPHIC CAMERA
(FR) DISPOSITIF POUR APPAREIL PHOTOGRAPHIQUE
Abstract: front page image
(EN)A holder (13) provided with a focusing screen (14) is connected with the back (11) of the camera by means of springs (15). A cam (17) secured to the back (11) of the camera and susceptible of being brought to two limit positions by means of a handle (26) cooperates with a slide (22) of the back (11). In the first limit position of the cam, the focusing screen holder (13) is pressed by springs (15) against the back (11). By pivoting the cam (17) towards its second limit position, the focusing screen holder (13) is lifted from the back (11) against the action of the springs (15). The cam (17) is provided with a control surface (52) which bears in sliding contact against a pusher (50). The pusher (50) is subjected to the action of a damper (36) so that the pivoting motions of the cam (17) from the second limit position to the first limit position are dampened in relation to the speed. Thereby, the focusing screen holder (13) is prevented from impacting violently under the action of the springs (15) against the back (11) of the camera or a cassette arranged between the back (11) and the focusing screen holder (13) and containing a film, which would cause vibrations and damages.
(FR)Un support (13) muni d"un verre dépoli (14) est relié avec le dos (11) de l"appareil au moyen de ressorts (15). Une came (17) fixée sur le dos (11) de l"appareil et pouvant être amenée en deux positions-limites au moyen d"une poignée (26), coopère avec une glissière (22) du dos (11). Dans la première position-limite de la came le porte-dépoli (13) est pressé par les ressorts (15) contre le dos (11). En pivotant la came (17) vers sa seconde position-limite le porte-dépoli (13) est soulevé du dos (11) à l"encontre de l"action des ressorts (15). La came (17) est pourvue d"une surface de commande (52) qui est appuyée en contact glissant contre un poussoir (50). Le poussoir (50) est soumis à l"action d"un amortisseur (36) de façon que les mouvements de pivotement de la came (17) de la seconde vers la première position-limite sont amortis en fonction de la vitesse. Ainsi on évite que le porte-dépoli (13) heurte violemment, sous l"action des ressorts (15), le dos (11) de l"appareil ou une cassette disposée entre le dos (11) et le porte-dépoli (13) et munie d"un film pour la prise de vue ce qui produirait des vibrations et des endommagements.
