Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic processor for a photosensitive material equipped with a charging device capable of automatically replenishing a solid photographic processing agent for processing a silver halide photographic photosensitive material.

[0002]

2. Description of the Related Art In an automatic processor for processing a silver halide photographic material, a photographic light-sensitive material is processed by developing, fixing and washing with water. Here, a developing solution is used for development and a fixing solution is used for fixing. These processing solutions are usually
The temperature is adjusted to 30 ° C to 40 ° C, and the photographic light-sensitive material is dipped in these processing solutions for processing. Since these treatment liquids deteriorate with treatment and aging, they are used by exchanging / replenishing or supplementing with a fresh one by a replenishment system or a patch system.

Conventionally, these photographic processing agents are supplied in a concentrated liquid form, and users often use them by diluting them. The mainstream of these treatment liquids is a packaging form using a plastic bottle as a container.

The liquid state of the photographic processing agent poses a problem in terms of transportation, and during transportation, precipitation occurs in the concentrated solution, making redissolution difficult.

Also, the used plastic bottle has a problem in disposal. In addition, the other types, such as the concentrated powder type, had a very bad environment for the user during the melting work. If the photographic processing agent is a kitted parts agent, it will be provided in a container such as a bottle or bag, but when the user puts the processing agent in the processing tank, each part agent will be blended without mistake, It was dissolved in advance and added to the treatment liquid, which required skill and manpower.

[0006]

In recent years, as a photographic processing agent that does not require skill or manpower and is error-free,
Solid processing agents have come to be considered.

This solid processing agent is enclosed in a moisture-proof packaging body made of a plastic sheet or the like in a required number in a continuous package, and the packaging material of the above-mentioned packaging body is introduced through a processing agent feeding device attached to an automatic processing machine. A method is used in which the processing agent is transported and opened, and the enclosed processing agent is dropped and replenished in the processing tank of the automatic processing machine.

Therefore, a long package is compactly set in the treatment agent feeding device to enable continuous replenishment of the treatment agent, and the package is opened for smooth and reliable transport and opening of the package. Therefore, it is necessary to remove the waste packaging.

The present invention solves this problem and improves as a result.
By adding a very simple device, it is possible to set long packages at the same time, and it is possible to automatically remove the above-mentioned packages that have been scrapped after being opened from the transport surface and compactly collect them. It is an object of the present invention to provide an automatic developing machine for a photosensitive material equipped with a processing agent charging device.

[0010]

The above object is to provide a solid-state photograph in which a continuous package in which a solid-state photographic processing agent is enclosed is continuously opened and the solid-state photographic processing agent is automatically replenished in a processing tank. In an automatic processor for a photosensitive material including a processing agent charging device, the solid photographic processing agent charging device detachably supports a container for accommodating the package and a recovery container for accommodating the opened package. It is achieved by the featured automatic developing machine for photosensitive materials.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of an automatic developing machine (hereinafter referred to simply as an automatic processor) to which the present invention can be applied will be described with reference to the drawings. Figure 1
FIG. 3 is a schematic view of a printer processor in which an automatic developing machine A and a photo printing machine B are integrally configured.

In FIG. 1, in the lower left part of the photo printing machine B,
A magazine M in which photographic paper which is an unexposed silver halide photographic light-sensitive material is housed in a roll is set. The photographic printing paper pulled out from the magazine is cut into a predetermined size via the feed roller R and the cutter section C to become a sheet-shaped printing paper. This sheet of photographic printing paper is conveyed by the belt conveying means B1, and the original image O is conveyed by the lens L in the exposure section E.
The image of is exposed. The exposed sheet-shaped printing paper is further conveyed by a plurality of pairs of feed rollers R and introduced into the automatic developing machine A. In the automatic developing machine A, the sheet-shaped photographic paper is a color developing tank 1A, a bleach-fixing tank 1B, and a stabilizing tank 1, which are processing tanks.
The rollers C (1D, 1E) (substantially three tanks) are sequentially conveyed by roller conveying means (reference symbol None).
Color development processing, bleach-fix processing, and stabilization processing are performed.
The sheet-shaped printing paper that has been subjected to each of the above processes is dried in the drying unit 35 and discharged to the outside of the machine.

The alternate long and short dash line in the figure indicates the transport path of the silver halide photographic light-sensitive material. In the embodiment, the light-sensitive material is introduced into the automatic developing machine A in a cut state, but it may be introduced into the automatic developing machine in the form of a strip. In that case, if an accumulator for temporarily retaining the photosensitive material is provided between the automatic developing machine A and the photoprinting machine B, the processing efficiency is improved. Needless to say, the automatic developing machine according to the present invention may be configured integrally with the photoprinting machine B or may be a single automatic developing machine. Further, it goes without saying that the silver halide photographic light-sensitive material processed by the automatic developing machine according to the present invention is not limited to exposed photographic paper, and may be exposed negative film or the like. Also,
The present invention will be described with respect to a developing machine having substantially three tanks including a color developing tank, a bleach-fixing tank, and a stabilizing tank, but the present invention is not limited to this, and the color developing tank, the bleaching tank, the fixing tank, The present invention can be applied even to an automatic developing machine having a substantially 4-tank structure having a stabilizing tank.

FIG. 2 is a schematic view of the color developing tank 1A which is a processing tank in the I-I cross section of the automatic developing machine A of FIG. The bleach-fixing tank 1B and the stabilizing tanks 1C, 1D, and 1E have the same configuration as the color developing tank 1A. Therefore, when the processing tank 1 is described below, the color developing tank 1A, the bleach-fixing tank 1B, and the stable tank are stable. All of the tanks 1C, 1D and 1E will be referred to. It should be noted that, in the figure, a transporting means for transporting the photosensitive material and the like are omitted for easy understanding of the configuration. Further, in this example, the case where the tablet 13 is used as the solid processing agent will be described.

The processing section 2 for processing the photosensitive material is a solid processing agent input section 11 for supplying a solid processing agent (tablet) integrally provided on the outside of the partition wall forming the processing section 2 and a constant temperature bath 3.
Have. The processing section 2 and the constant temperature bath 3 are partitioned by a partition wall 12 having a communication window formed therein so that the processing liquid can flow. Since the enclosure 10 for receiving the solid processing agent is provided in the charging section 11 provided above the constant temperature bath 3, the solid processing agent does not move to the processing section 2 in a solid state. It should be noted that the enclosure 10 has a mesh-like or filter-like shape that allows the treatment liquid to pass therethrough, but does not allow the solid treatment agent to pass until it is completely dissolved.

The cylindrical filter 14 is provided below the constant temperature bath 3 so as to be replaceable, and has a function of removing insoluble matter such as paper waste in the treatment liquid. Inside this filter 14,
It is connected to the suction side of a circulation pump 5 (circulation means) via a circulation pipe 4 which penetrates the lower wall of the constant temperature bath 3.

The processing amount information detecting means 8 is provided at the entrance of the developing machine and is used for detecting the processing amount of the photosensitive material to be processed. The processing amount information detecting means 8 has a plurality of detecting members arranged in the left-right direction and functions as an element for detecting the width of the photosensitive material and for counting the detected time. Since the conveying speed of the photosensitive material is mechanically preset, the processing area of the photosensitive material can be calculated from the width information and the time information. The processing amount information detecting means 8 may be any one capable of detecting the width and the conveying time of the photosensitive material such as an infrared sensor, a micro switch, an ultrasonic sensor and the like. Further, 9 is a control means for receiving the signal from the processing amount information detecting means 8 and controlling the processing amount supply of the processing agent.
