    • Dispositif pour la détection de l'ouverture d'un compteur, le compteur (3) comportant au moins un premier élément structurel (1) et un second élément structurel (2) dans une position relative donnée lorsque le compteur est fermé, caractérisé en ce qu'il comprend :

      un organe mobile (4) relié au premier élément (1) et prévu pour adopter un état stable ou un état instable en fonction du déplacement d'un des éléments structurels (1,2) par rapport à l'autre ;
      des moyens de maintien reliés au moins au second élément (2) et coopérant avec l'organe mobile (4) en fonction du déplacement d'un des éléments structurels (1, 2) par rapport à l'autre, de manière à le maintenir dans son état instable et à permettre son passage à son état stable ;
      des moyens de détection (16, 17, 18) aptes à déterminer l'état dans lequel se trouve l'organe mobile (4) et à émettre un signal d'ouverture lorsque l'organe mobile (4) est dans un état prédéterminé.

    • A photographic camera (103) is disclosed for use with a film cassette (1) in which a filmstrip (F) has a row of metering perforations (P) in its imaging portion (I), adjacent a longitudinal film edge (63), for engagement with a metering pawl (125) of the camera, and a row of take-up perforations (T) in its leader portion (L), adjacent the same film edge (63), for engagement with a take-up spool (121) of the camera, and a film spool (5) is rotatable to unwind the filmstrip off the spool to thrust the leader portion from the cassette. The camera includes a film sensing member (135) for normally maintaining the metering pawl removed from a film advance path (119) between the cassette and the take-up spool to prevent the pawl from erroneously engaging the leader portion at one of its take-up perforations. The sensing member is actuated to release the metering pawl, to allow the pawl to be moved into the film advance path to engage the imaging portion at one of its metering perforations, only after the leader portion has been advanced sufficiently from the cassette to move its take-up perforations out of reach of the pawl.
