Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a processing apparatus for photographic materials.

[Conventional technology]

Generally, exposed photographic materials, such as photographic film and photographic paper, are developed by sequentially passing through processing tanks for development, fixing, stabilization, washing, etc., which are arranged in parallel in an automatic developing device. It is processed and then subjected to drying, cutting and other steps to create a product print.

By the way, in recent years, from the viewpoint of speeding up the development processing, it has become advantageous to perform a series of processing steps of photographic light-sensitive materials continuously, from exposure and baking to development, and automatic printing equipment-automatic development equipment systems have been developed for this purpose. development is desired.

However, with this systemization of automatic printing equipment and automatic developing equipment, the maximum processing speeds of the two equipments are significantly different, making it difficult to operate both of these equipments with high efficiency while conveying photographic light-sensitive materials smoothly and continuously. Have difficulty.

[Problem that the invention seeks to solve]

The present invention solves problems in systematization with automatic printing equipment, allows smooth development processing of exposed photographic materials that are continuously transferred from automatic printing equipment, and allows for smooth development of exposed photographic materials that are continuously transferred from automatic printing equipment. It is an object of the present invention to provide a processing apparatus for photographic light-sensitive materials that can continuously and efficiently perform printing and developing processing of photographic light-sensitive materials in a series of steps by combining the following methods.

[Means and actions for solving problems]

The above-mentioned problem consists of a printing section that performs exposure printing on an unexposed photographic material, a first storage section that temporarily stores the photographic material transferred after being exposed in the printing section, and A photographic material processing apparatus comprising: an automatic developing device for developing exposed photographic material; and a cutter provided upstream of the first storage section; a second storage section provided between the developing device; a means for transporting the photographic material between the first storage section and the second storage section; and means for controlling the speed of the transport means. The control means normally sets the conveying means at a speed equivalent to the processing speed of the automatic developing device, and controls the first speed in response to cutting of the photographic light-sensitive material by the cutter. A processing device for photographic light-sensitive materials, characterized in that the photographic light-sensitive material accumulated in the storage section is controlled to be transferred to the second storage section at a speed faster than the processing speed of the automatic developing device. It is achieved by doing so.

In the apparatus with the above configuration, a paper sheet for accumulating photographic material is placed upstream of various processing tanks for development, fixing, stabilization, washing, etc., that is, between these processing tanks and the inlet of the exposed photographic material. By providing an accumulator section and temporarily accumulating photographic material supplied at a moving speed higher than the processing speed of the automatic developing device, the photographic material transported from the automatic printing device can be continuously processed. Development processing can be carried out smoothly.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an explanatory front view schematically showing the internal structure of the automatic developing device A according to this embodiment, with the front side plate removed.

1 indicates the main body of the device, and the main body 1 of the device is the case 11.
The inside is in a light-shielded state. On one side plate of the case 11 is an exposed photographic material (hereinafter referred to as
Entrance 1 for introducing paper (simply referred to as "paper")
2. The other side plate is provided with an outlet 13 for discharging the developed paper.

Inside the apparatus main body 1, from the inlet 12 side to the outlet 13 side, there are a paper accumulator section 2 as an accumulation section for temporarily storing paper, a developing processing section 3 consisting of a plurality of processing tanks, and A drying section 4 for drying the paper after the development process is sequentially provided.

The paper accumulator section 2 has a box shape as a whole, and guides 21 and 22 are provided at the upper part of the paper accumulator section 2.
The movable guide 23 forms a paper path P that extends diagonally upward.

The movable guide 23 is located at the lower part of the paper path P, and one upper end thereof is pivotally supported, and the middle part thereof is connected to one end of the spring 24. By selecting the tensile force of the spring 24, the movable guide 23 is arranged along the paper path P in a normal state, that is, a state in which the paper is transported at the developing processing speed, and in an emergency state, that is, a state in which the paper is transported at the developing processing speed. In a state where the paper is transferred at a higher speed, it is configured to rotate in a direction away from the paper path P by the pressing force of the paper.

A conveyance roller 25 is driven at a constant speed to convey the paper at the development processing speed. 26
-28 are guide rollers that guide the paper.

The development processing section 3 includes a developer tank 31 and a bleach-fix tank 3.
2. First rinse tank 33 and second rinse tank 34
are sequentially arranged in parallel, and each tank is provided with rollers 30a and 30b for conveying paper.

In the drying section 4, hot air is blown onto the paper after the development process using, for example, an air blower (not shown) to dry the paper.

In the figure, R1 and R2 are the inlet 12 and the outlet 1
A pair of feed rollers provided at 3. Also 5
Reference numerals 1 and 52 are tanks for waste liquid discharged from each of the processing tanks 31 to 34.

The automatic developing device A described above is used, for example, in direct connection with the automatic printing device B shown by the chain line in FIG. The automatic printing device B used in this example is:
The paper accumulator section 62 has a paper accumulator section 62 as a storage section that temporarily stores paper transferred from a printing processing section 61 that exposes unexposed paper to form a latent image.
The paper inside is discharged by a pair of feed rollers R3 at a transport speed corresponding to the processing speed of the automatic developing device A.

The paper that has been subjected to the exposure process in the automatic printing device B and discharged by the feed roller R3 is transported into the main body 1 of the device by the feed roller R1 through the entrance 12 of the automatic developing device A in a light-shielded state, and is further passed through the guide 21, 22 and a movable guide 23, and transported to the development processing section 3. Then, the paper is immersed in each processing liquid while sequentially passing through each processing tank 31 to 34 of the development processing section 3, and is subjected to a predetermined processing. The paper is then dried while passing through the drying section 4, and is discharged from the main body 1 of the apparatus from the outlet 13 by the feed roller R2, after which it undergoes cutting and other processes to become printed products.

As the printing and developing process progresses in this way,
Since the processing speed in the automatic printing apparatus B is normally set higher than the processing speed in the automatic developing apparatus A, exposed paper is accumulated in the paper accumulator section 62 of the automatic printing apparatus B. Then, when the exposure process in the automatic printing apparatus B is interrupted, the paper is cut by a cutter (not shown) in the automatic printing apparatus B, and only the exposed paper is accumulated in the paper accumulator section 62. When such a paper cut is performed, it is impossible to transfer subsequent paper while exposed paper remains in the paper accumulator section 62. Therefore, in order to perform the next exposure process, it is necessary to wait until the paper in the paper accumulator section 62 is completely transferred to the automatic developing device A. However, if such paper were to be transported at a steady speed, that is, at the processing speed of automatic developing device A, it would take a long time to transport the paper, and as a result, the operating rate of the automatic printing device for processing photographic materials would be low. There's a problem.

However, the photographic material processing apparatus of the present invention has a paper accumulator section 2 in which exposed paper supplied from the automatic printing apparatus B can be temporarily stored.
Paper accumulator section 62 of automatic printing device B
It becomes possible to rapidly transport the cut paper remaining in the paper at a transport speed sufficiently higher than the normal speed, and the above-mentioned problem is solved. When the paper is rapidly fed in this manner, since the speed of the conveyance roller 25 is constant, the movable guide 23 is pressed by the paper and rotates in a direction away from the paper path P against the tensile force of the spring 24. It moves and becomes open. Then, the paper falls into the paper accumulator section 2 due to its own weight and is accumulated there.

Although one embodiment of the present invention has been described above, the present invention is not limited thereto, and for example, the configuration of the paper guide in the paper accumulator section can be modified as appropriate.

〔Effect of the invention〕

In the present invention, there is provided a first paper accumulator section for temporarily accumulating photographic material transferred after being exposed in a printing section, and a space between the first paper accumulator section and an automatic developing device. A second paper accumulator section provided in When the photographic material being transported upstream of the first paper accumulator section is cut, the photographs accumulated in the first paper accumulator section are Since the photosensitive material is transferred to the second paper accumulator section at high speed by the conveying means, the subsequent photographic photosensitive material after cutting is immediately transferred between the first paper accumulator section and the second paper accumulator section. It is also possible to carry a conveying means between the first paper accumulator section and the subsequent photographic material can be accumulated in the first paper accumulator section. Exposure can be performed. Therefore, it is possible to easily systemize an automatic printing device and an automatic developing device, and there is an advantage that efficient processing of photographic materials can be carried out.
