Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera processor that can perform image exposure, development, fixing, washing, drying, and other steps in an integrated manner. In particular, the present invention relates to a camera processor that can consistently perform the above exposure and development steps on a large amount of elongated photosensitive material.

2. Description of the Related Art Conventionally, various methods have been proposed and put into practical use in which photographing and developing of photosensitive materials such as microfilms are carried out in an integrated manner. These devices have a photographing section and a developing section installed in series, and perform photographing on microfilm, etc., and subsequent development, fixing, washing, drying, etc., continuously or consistently. Since the feeding speed and the feeding speed of the photosensitive material during the development process are different, various methods have been adopted to carry out both processes continuously or consistently.

For example, one method is to provide a buffer chamber between the photographing section and the developing section, and store the exposed film in a loop shape, absorbing the difference in speed between the photographing section and the developing section. , a storage room is provided in place of the buffer chamber, a certain amount of exposed film is stored there, and when a certain amount is reached, the film is cut, shooting is stopped, and the stored film is developed. There are known methods for starting the process. However, while the former method has the effect of allowing photographing and development to be carried out at the same time, there is a risk that static electricity and scratches may occur due to the films rubbing against each other when the loop is formed, and that the loop may not be formed. Since it is essential that the loop be detected, complex means such as a sensor to detect the loop and adjustment of the shooting speed depending on the loop condition are required. In the latter case, as in the former case, when the film is stored in a loop, there is a risk that the film will rub against each other, causing static electricity and scratches, and also due to the practical size of the storage chamber. The amount of film that can be produced is limited to several meters, making it impossible to process large amounts of film.

As another method, a method has been proposed in which the photographed photosensitive material is once wound onto a reel in a storage chamber, cut, and then the reel is reversed and sent to a developing device (Japanese Patent Laid-Open No. 56-43632). This method allows photographed photosensitive material to be stored and processed without causing the above-mentioned troubles, but it has the disadvantage that once development has started, the next photosensitive material cannot be photographed until all the wound-up photosensitive material is used up. Ta.

According to the present invention, it is possible to store and develop a large amount of imagewise exposed or photographed photosensitive material without causing the above-mentioned troubles due to the formation of loops, etc., and it is also possible to carry out the next imagewise exposure or photographing even during development processing. The aim is to provide a camera processor that can.

That is, the present invention provides a means for imagewise exposing a long photosensitive material, a means for winding up and storing the long photosensitive material exposed by the imagewise exposing means in a roll shape, and a method for storing the photosensitive material stored in the storage means. In a camera processor equipped with a cutter for cutting and means for photographically processing the photosensitive material fed from the storage means, such as developing and fixing, an image exposure track and a development track are arranged side by side in the same plane, and the exposure track While the storage means is disposed on the side, a means for receiving the photosensitive material is provided at a position opposite to the storage means on the side of the developing track, and the photosensitive material is reciprocated between the tracks to be cut by the cutter. The camera processor is characterized in that it is provided with a storage unit that delivers the photosensitive material stored in the storage means to the receiving means.

The present invention will be explained below with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the camera processor of the present invention, and FIG. 2 is a plan view thereof.

In the figure, 1 is an image exposure section (hereinafter referred to as the photographing section), 2 is a storage unit, and 3 is a developing section.As shown in FIG. ) and a developing track are provided in the same plane so as to form separate tracks. An original 13 is photographed via an optical system 6 on a photosensitive material (hereinafter referred to as a film) 4 which is continuously fed out from a reel 5 along a photographing track, and is sent to a storage unit 2 by rollers 7, 7'. The photographed film 4 that has been sent out is further fed in by pinch rollers 9, 9' within the storage unit 2, guided by a member 12, and wound around a core 11 provided on one side wall of the storage unit 2. At this time, as shown in FIG. 3, the core 11 has a plurality of projections 14 projecting in the radial direction of the core to facilitate winding of the film 4. When the desired amount of photographing is completed, the photographed film 4 is fed until it passes through the cutter 8 by operating the development start button, and then the cutter 8 is operated to cut the film 4.

In response to the operation end signal of the cutter 8, the portion of the storage unit 2 that holds the photographed film 4 is moved in parallel within the same plane from position A on the photographing track side to position B on the developing track side, as shown in FIG. . A side view of the state of movement of the roll-shaped film 4 due to the above-mentioned movement of the storage unit 2 is shown in FIGS. 3 and 4.
Shown in the figure. In FIGS. 3 and 4, the pinch rollers 9, 9' are located on the photographing track side, which is the winding side of the storage unit 2.
0' and the receiving roller 15 are provided on the developer track side of the storage unit 2. When the rolled film 4 is at position A, the feed rollers 10, 1
0' are released to a spaced apart condition as shown in FIG. Storage unit 2 moves to position B,
The rolled film 4 is placed on the receiving roller 15, and when the leading edge of the film 4 is positioned on the developing feed roller 10', one or both of the feeding rollers 10, 10' move and close to sandwich the leading edge of the film. , the pinch rollers 9 and 9' are released to open as shown in FIG.
is stored in the core (inward in the radial direction of the core) and released from the roll-shaped film 4. Next, each member of the storage unit 2 used for winding the film returns to the photographing track position A, leaving the rolled film 4 at position B. The roll-shaped film 4 at position B is kept sufficiently stable by the receiving roll 15 alone, but in order to further securely hold the film, it may be held by fitting it into another core from the side wall of the developing track. good.

The rolled film 4 moved to position B is pulled out by feed rollers 10 and 10' and sent to the developing section 3, and passes through, for example, a developing tank 16, a fixing tank 17, a washing tank 18, and a drying section 19. be wound up. On the other hand, in the storage unit 2, since the member for winding up the photographed film 4 has already been returned to the position A of the photographing truck, photographing can be started again.

In the above example, the core 11 in the storage unit 2, the member 12 for winding the film 4 around the core 11, the pinch rollers 9, 9', etc. were all moved, but this is not limited to this embodiment. This method may also be used. For example, as shown in FIGS. 5 and 6, a photographing track (A side) and a developing track (B side) are provided somewhat close to each other, and a core 11 and a core 11 are placed on the photographing track side and the developing track side, respectively. ′
are placed so as to face each other, and after the photographing is completed, only the side plate 2a through which the core 11 is penetrated is moved toward the B side, and only the rolled film 4 is removed from the core 11, and the core 11' is You can also move it so that it fits. Although the present invention has been described above in the case of photographing and developing microfilm, the present invention can be applied not only to microfilm, but also to continuous printing and development of light-sensitive materials such as color paper.

As described above, according to the present invention, since photographed film is stored in a roll in a storage unit, a large amount of film can be photographed continuously, and the developing process is carried out on a developing track provided separately from the photographing track. The reciprocally movable photosensitive material receiving means allows the roll-shaped film to be quickly transferred within the same plane without the need for human intervention, and since the newly exposed film is already ready to be wound, it is possible to easily transfer the film during development. It is also possible to take pictures with a camera, and its processing capacity can be greatly improved compared to conventional camera processors.
