Abstract

L'invention se rapporte à un dispositif d'enroulement de pellicule pour appareil photographique, dans lequel un moteur d'entraînement 21 est logé dans une bobine d'enroulement de pellicule 11, et un arbre de sortie 15 du moteur d'entraînement fait saillie de la bobine d'enroulement de pellicule 11. Un mécanisme réducteur 50 est prévu entre l'arbre de sortie et la bobine d'enroulement de pellicule afin d'entraîner en rotation la bobine d'enroulement de pellicule et d'enrouler une pellicule autour de celle-ci. Le mécanisme de réduction comprend une roue dentée mère 51 tournant en association avec l'arbre de sortie, une roue dentée satellite 52 prévue à une position décalée par rapport au centre de la roue dentée mère, une roue dentée fixe 53 fixée au corps 19 de l'appareil photographique, et une roue dentée rotative 54 reliée au dispositif d'enroulement de pellicule. La roue dentée fixe 53 et la roue dentée rotative 54 sont coaxiales à la roue dentée mère 51 et en prise avec la roue dentée satellite 52. La roue dentée rotative 54 tourne par rapport à la roue dentée fixe 53, si bien que la roue dentée satellite 52 est entraînée en rotation à une vitesse de rotation qui est fonction de la différence entre le nombre de dents de la roue dentée fixe et le nombre de dents de la roue dentée rotative.
