PURPOSE:To permit the tail of an exposed part to arrive at a development part in a constant time, by providing ratchet device to the storage reel, which takes up the exposed part around a storage reel during photographing through driving the storage reel forward and then permits the reel to be driven by the reversed exposed part during development. CONSTITUTION:In forward-backward path 14a, pinch roll 19 is provided which is driven to rotate sandwiching the exposed part during development and reverses the exposed part, and storage reel 10 or its shaft is provided with ratchet device 21 which permits storage reel 10 to rotate forward during photographing to take up the exposed part and to be driven by the reversed exposed part during development. Ratchet device 21 is provided with ratchet disk 21a, annularly arranged projections 21', and ratchet pawl 21b. |
