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 photographed film in a relaxed loop, so that the difference in speed between the photographing section and the developing section is absorbed by the buffer chamber. , a storage room is provided in place of the buffer chamber, a certain amount of film that has been shot is stored there, and when a certain amount is reached, the film is cut, shooting is stopped, and the stored film is developed. Methods for starting the process are known. However, in the case of the former, although it has the effect of being able to perform photography and development at the same time, it is essential that a loop is formed.
Multiple means are required, such as a sensor to detect loops and adjusting the shooting speed depending on the loop status. In the latter case, the film is stored in a loop, and after cutting, it is inefficient that the next photographing cannot be started until the film in the storage chamber becomes extremely small or almost completely gone.

An object of the present invention is to provide a camera processor equipped with a photosensitive material storage device that does not require complicated means and can perform the next image exposure or photographing in an extremely short period of time even during development processing of photographed photographic material. The purpose is

That is, the present invention provides a camera processor equipped with means for imagewise exposing a long photosensitive material, a storage chamber for storing the imagewise exposed photosensitive material, a cutter for cutting the photosensitive material, and a means for developing the stored photosensitive material. A camera processor characterized in that a storage chamber between an image exposure means and a development means is provided with a photosensitive material holding member that moves between an entrance on the image exposure side and a feed roller that feeds the photosensitive material to the development side.

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.

In the figure, 1 is an image exposure section (hereinafter referred to as the photographing section);
2 is a storage chamber, and 3 is a developing section, which are arranged so that the photographing section 1 and the storage chamber 2 form an image exposure track (hereinafter referred to as a photographing track), and the storage chamber 2 and the developing section 3 form a developing track. It is being

A photosensitive material (hereinafter referred to as film) 11 is continuously fed out from a reel 4 along a photographing track.
The original 7 is photographed by the optical system 5, and the roller 6,
At 6', it is sent to the storage room 2.

In FIG. 2, the photographed film 11 that has been sent out is held at the entrance of the storage chamber 2 by the photosensitive material holding members 9, 9' (hereinafter referred to as holding rollers) rotating in synchronization with the photographing process, so that the vicinity of the tip is held. Retained. (as shown in Figure 2a).

When the near end of the film is gripped, the thickness of the film or the leading end is detected and the rollers 9, 9' stop rotating.

When photographing is subsequently performed, the holding rollers 9, 9' remain in synchronization with the photographing, and while the rotation of the rollers 9, 9' itself is stopped, the inlet and feed rollers 10, 10'
It advances to a predetermined position between and stops once, and as a result,
The film 1 is placed between the holding roller and the entrance.
It is stored downward in a loop shape due to its own weight (as shown in Figure 2b). When the capacity reaches an acceptable capacity,
Alternatively, when the desired amount of photographing is completed, the holding rollers 9, 9' move to the developing side by operating the developing start button, start rotating again, and move the feed roller 1 on the exit side.
The film 11 is delivered and supplied to the terminals 0 and 10' (as shown in c in FIG. 2), and after the photographed film is fed until it passes the cutter 8, the cutter 8 is operated to cut the film 11 and cut the film 11 at the rear end of the film. into the storage chamber (as shown in Figure 2 d). or,
After the leading edge of the film is held by the feeding rollers 10, 10', the holding rollers 9, 9' release the holding of the film 11 and return to their original positions to hold the new film 11 that is fed next ( (shown in e of Figure 2). The release can be carried out, for example, by sliding the lower roller 9' horizontally in the A direction as shown in FIG. 3, or by rotating it in the B direction and pulling it in.

On the other hand, the film 11 sent to the developing section 3 is wound up through the transfer groove 13 in the order of development, fixing, washing, and drying. With this configuration, photographing and developing can be performed almost simultaneously, and since the photographing track and the developing track are performed separately, there is no need to adjust the photographing speed to the developing speed.

In the above example, the movement of the holding rollers 9, 9' is such that the film 11 is stored at an intermediate position and then fed to the feed rollers 10, 10'. It may depend on the method. For example, the time required for the film 11 to reach a predetermined capacity is synchronized with the time required for the holding rollers 9, 9' to move from their home positions to the feed rollers 10, 10', and ′
When it is sensed that the film 11 is held by the holding rollers 9, 9', the holding rollers 9, 9' may be released and returned to their original positions. Further, in place of the holding rollers 9, 9', pressing plates 12, 12' or the like may be used as shown in FIG.

In this case, the locking members 12, 12' are released until the leading edge of the film is detected, and the film is moved from the locking members 12, 12' so that the leading edge of the film can be delivered to the exit rollers 10, 10'. When the film protrudes, the film is gripped in response to a detection signal from a film detector attached to the locking members 12, 12'. Thereafter, it operates in the same manner as the previous embodiment.

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.

By having the above-described structure, the present invention enables the photographed film to be cut and sent from the storage chamber to the developing truck side, and the next photograph can be taken in an extremely short time, and the speed difference between developing and photographing is extremely small. Even if the image size is large, the next photographing can be easily carried out during the development process.
