DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a transport mechanism for transporting a photographic material in a plurality of processing tanks, and is capable of being divided into an upper unit and a lower unit near a processing liquid level. The present invention relates to a configured processing rack unit.

[0002]

2. Description of the Related Art When a photographed material is developed to develop a photographed image, the film is generally immersed in a processing tank filled with a processing solution for color development and fixing for a predetermined time. Let me do it. Each processing tank is provided with a processing rack unit for transporting the photosensitive material. This processing rack unit includes transport rollers,
Members such as a roller driving mechanism and a guide plate are provided. By the way, the processing liquid adheres to the transfer roller and the like provided in the insertion section and the discharge section of the photographic photosensitive material located above the processing liquid level of such a processing tank, and further, it is crystallized and deteriorated. Since this phenomenon hinders the conveyance of the photographic light-sensitive material, it is necessary to wash it periodically. or,
On the other hand, since the processing liquid is agitated below the processing liquid level in the processing tank, crystallization is less likely to occur than above the processing liquid level, and thus the necessity of cleaning is relatively small. Further, in cleaning, it is necessary to take out the processing rack unit from the processing tank, which requires great labor. From such a viewpoint, it is known that the processing rack unit can be divided into an upper unit and a lower unit near the processing liquid level, and only the upper unit can be removed from the lower unit.

For example, in JP-A-58-95738 (known art 1), a rack unit is divided into an upper part and a lower part so as to be detachable. By pulling the handle upward, the upper lock shaft can be moved to release the engagement with the lower hook, and the handle can be further raised to divide the upper portion from the lower portion. Also, Japanese Patent Laid-Open No.
In Japanese Patent No. 2646 (Publication 2), the upper rack and the lower rack are fastened with screws, and the two can be separated by removing the screws.

[0004]

However, in the above-mentioned prior art 1, the handle is lifted up by a predetermined distance to release the lock, and the handle is lifted from that state to divide the upper unit. This means that the upper unit cannot be removed unless the handle is lifted to some extent by hand, and the operation for unlocking and the operation for removing the upper unit cannot be separated. Thus, although the upper unit can be removed from the lower unit, it has not been convenient. Also, as shown in FIG. 4 of JP-A-58-95738, the grips are provided on both sides of the rack.
When removing the upper unit, it was necessary to work with both hands, and it was sometimes said that safety was poor. Further, in the known technique 2, since the removal is performed by a screw, it is even more inconvenient. SUMMARY OF THE INVENTION An object of the present invention is to provide a split-type processing rack unit from which an upper unit can be easily removed, and a photographic processing apparatus provided with the same.

Further, since the operation unit 26 is attached in a state of being exposed on the upper surface of the upper unit 13, the operability is good. The upper unit 13 can be removed from the lower unit 14 in the state of FIG. In this case, since the upper unit 13 can be sufficiently lifted with one hand, it can be removed with one hand when the device is at a relatively high place, for example, when performing the removal work on a step platform. You can support your body with your hands and work safely.

Further, the lock release lever 25 is moved to the position shown in FIG.
In this state, the posture is maintained against the urging force of the spring 30. This can be achieved by various methods such as locking the lock release lever 25 at the position shown in FIG. 5B or holding the lock release lever 25 with a frictional force acting between the pin 32 and the cam groove 29. Is raised.

As described above, since only the upper unit 13 can be removed and washed without removing the lower unit 14 from the processing tank, the labor of the operator is reduced. In particular,
The upper unit 14 can be easily removed, and the number of times of cleaning can be increased. As a result, the life of the parts of each part and the life of the photo developing device 100 can be prolonged. Further, the occurrence of trouble can be suppressed.

Further, another embodiment of the present invention will be described. In the present embodiment, the lock release lever 25 is manually driven by the operator, but the lock may be released using a drive source such as a motor. Although the urging force acts on the lock release lever 25 by the spring 30, a spring may be provided so that the urging force acts directly on the lock rod 31. Although a film development processing device is shown here as an example of a photographic photosensitive material, it is obvious that the same can be applied to a rack unit in a photographic paper processing device.
