Abstract
Abstract Combination photographing and developing apparatus incorporates in the photographing section thereof a storage reel capable of being selectively rotated in the forward or rearward direction in addition to a payoff reel having a roll of film thereon. During photography, the storage reel is rotated in the forward direction synchronously with the photographing operation to take up the exposed portion of the film thereon. When the photographing operation is completed, the film is cut at the tail end of the exposed portion thereof and the storage reel is rotated in the rearward direction, so that the exposed portion of the film is forwarded, with the cut tail end thereof in the lead, to the developing section, there to be developed and dried.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
282 words
In a combination photographing and developing apparatus operated by mounting in the photographing section thereof a roll of film wound on a payoff reel, advancing the film from the payoff reel along a guide route by a film feed means, effecting photography by exposing the film to given data, cutting the film with a cutter behind the end of the exposed portion thereof, forwarding the exposed portion of the film, with the cut end in the lead, through the outlet of the photographing section to the inlet of the developing section, and leading the film along a developing route passing through developing, fixing, and washing liquid tanks and a drying means in the developing section thereby effecting the development and drying of the film, the improvement wherein the photographing section thereof comprises in combination a storage reel disposed before said guide route and adapted to be selectively advanced in the forward or rearward direction, means for rotating said storage reel in the forward direction synchronously with the photographing operation, said forward rotation of the storage reel enabling the exposed portion of the film to be rewound on the storage reel, a vertical guide route formed between said storage reel and the outlet for the exposed portion of the film, said guide route having the leading end thereof join said vertical guide route halfway along the length thereof, a cutter disposed between the position for film exposure and the leading end of said guide route and adapted to cut the film behind the exposed portion thereof, and means for advancing the exposed portion of the film, with the cut tail end thereof in the lead, through said vertical guide route toward the outlet.

In a combination photographing and developing apparatus operated by mounting in the photographing section thereof a roll of film wound on a payoff reel, advancing the film from the payoff reel along a guide route by a film feed means, effecting photography by exposing the film to given data, cutting the film with a cutter behind the end of the exposed portion thereof, forwarding the exposed portion of the film, with the cut end in the lead, through the outlet of the photographing section to the inlet of the developing section, and leading the film along a developing route passing through developing, fixing, and washing liquid tanks and a drying means in the developing section thereby effecting the development and drying of the film, the improvement wherein the photographing section thereof comprises in combination a storage reel disposed before said guide route and adapted to be selectively advanced in the forward or rearward direction, means for rotating said storage reel in the forward direction synchronously with the photographing operation, said forward rotation of the storage reel enabling the exposed portion of the film to be rewound on the storage reel, a vertical guide route formed between said storage reel and the outlet for the exposed portion of the film, said guide route having the leading end thereof join said vertical guide route halfway along the length thereof, a cutter disposed between the position for film exposure and the leading end of said guide route and adapted to cut the film behind the exposed portion thereof, and means for advancing the exposed portion of the film, with the cut tail end thereof in the lead, through said vertical guide route toward the outlet.
Claim 3
Dependent Claim
43 words
The combined photographing and developing apparatus according to claim 1, wherein the outlet for the exposed portion of the film of the photographing section is connected to the inlet of the developing route in the developing section, with the joining point sealed optically.
Claim 4
Dependent Claim
165 words
The combined photographing and developing apparatus according to claim 1 or claim 2, wherein the photographing section comprises a housing incorporating therein a camera, driving means for operating a film feeding means, forward-motion driving means for advancing a storage reel at least in the forward direction, and means for operating the cutter and adapted to be closed tightly with a lid and a cassette possessed of film feeding means, a payoff reel, a storage reel, and a cutter as built-in components and further provided with an inlet for photographing light, a guide route, a vertical guide route, and an outlet, said cassette being so adapted that when it is mounted in position within said housing, said film feed means is interlocked with the driving means thereof, the storage reel with the forward-motion driving means, and the cutter with the cutter operating means respectively and, at the same time, said outlet is closed at all times with a shutter capable of opening and closing the outlet.
Claim 5
Dependent Claim
109 words
The combined photographing and developing apparatus according to claim 3, wherein the housing is provided with a second outlet adapted to communicate with the outlet and further with the inlet of the developing route in the developing section when the cassette is mounted in position within the housing, the housing is further provided between the housing body and the cassette means adapted so that, when the cassette is mounted in position within the housing, said means opens the shutter serving to keep the outlet of the cassette closed, and the forward-motion driving means for the housing incorporates means for switching the direction of the rotation of said driving means.
Claim 6
Dependent Claim
45 words
The combined photographing and developing apparatus according to claim 3, wherein the inlet of the cassette for admitting photographing light is normally kept closed with a freely openable shutter which is adapted to be opened when the cassette is mounted in position within the housing.
Claim 7
Dependent Claim
50 words
The combined photographing and developing apparatus according to claim 1, which further comprises means for advancing the film along the guide route toward the storage reel prior to causing the cutter to cut the film, so that the film will be cut behind the end of the exposed portion thereof.
Claim 8
Dependent Claim
57 words
The combined photographing and developing apparatus according to claim 1, which further comprises means for rotating the storage reel in the forward direction after the exposed portion of the film has been cut with the cutter, thereby bringing the cut tail end of the exposed portion of the film to a position in the vertical guide route.
Claim 9
Dependent Claim
61 words
The combined photographing and developing apparatus according to claim 1, which further comprises a pair of pinch rolls disposed in the vertical guide route between the storage reel and the forward end of the guide route and adapted to nip the exposed portion of the film and advance the film toward the film outlet rearwardly while the film is being developed.
Claim 10
Dependent Claim
72 words
The combined photographing and developing apparatus according to claim 8, which further comprises a ratchet means capable of rotating the storage reel in the forward direction thereby causing the exposed portion of the film to be rewound on the storage reel during the photographing operation and allowing the storage reel to rotate in the rearward direction owing to the rearward advance of the exposed portion of the film during the developing operation.
