The invention concerns an apparatus for intentional double exposure in photographic cameras (2) equipped with exchangeable film cartridges (1) of the type "magazine 70" and "magazine 100/200" manufactured by Victor Hassleblad AB, Gothenburg. The film cartridge's upper outer bracket arm (4) is fitted with a double exposure rewinder (3), which is operated by a reversing spring (6), and also fitted with a declutching notch (8). For double exposure, the double exposure rewinder (3) is turned in accordance with the camera's instructions so that the declutching notch (8) engages with the outer edge ratchet (21) of a cam disc (9) in the film advance mechanism, whereby the latter is declutched and enables the required double exposure.<IMAGE> |
