CA 2157993

There is presented a camera comprising a housing, and a generally cylindrically-shaped can rotatably mounted in the housing. The can is provided with an elongated opening extending lengthwise of the can, an external surface for supporting a negative film strip, and an internal surface for retaining a rolled film processing pad strip. An end of the negative film strip and an end of the processing pad strip are fixed to a foil having adhesive thereon for holding the foil on the can external surface and for covering the elongated opening to seal the can. The foil is peelable from the can and from the opening by pulling of the negative film strip from the external can surface.Movement of the foil away from the camera is operative to draw the processing pad strip from within the can while simultaneously drawing exposed negative strip from the camera, with the pad strip overlying the negative strip.

'invention est un appareil photo constitué d'un boîtier et d'un contenant que l'on peut faire tourner, généralement cylindrique, monté sur le boîtier. Ce contenant porte une ouverture étroite dans le sens de la longueur; la surface externe sert de support à une bande de pellicule négative et une bande de tampon de développement de la pellicule enroulée est fixée sur la surface interne. L'une des extrémités de la bande négative et une bande tampon sont fixées à une feuille métallique qui est elle-même fixée à la surface externe du contenant au moyen d'un adhésif et obture l'ouverture étroite du contenant. On peut enlever la feuille métallique fixée au contenant et obturant l'ouverture en tirant sur la bande de pellicule négative pour la décoller de la surface externe du contenant. Le mouvement d'éloignement de la feuille métallique par rapport à l'appareil photo provoque l'extraction de la bande de tampon de développement du contenant et simultanément, l'extraction de la bande de pellicule négative exposée de l'appareil photo, la bande de tampon étant superposée à la bande de pellicule.
