Description

[Detailed Description of the Invention] The present invention is an improved automatic developing device for photographic materials, particularly long photographic materials wound into rolls, and a drying device for forming an automatic developing machine. It is about improvement.

Conventionally, when processing photographic materials such as rolled photographic film and photographic paper (hereinafter referred to as "paper"), especially for color, there has been a The so-called automatic developing machine is constructed by arranging in series an automatic developing unit that performs a developing process on the photographic material and a drying unit that performs a drying process on the photographic light-sensitive material processed by the automatic developing unit. However, in the past, automatic processors of this type had
Alternatively, it is possible to distinguish between periods when large amounts of photographic film or large papers are processed, such as during the tourist or wedding seasons, and off-season periods, when processing is less concentrated, and to adjust the amount of processing. Since there is no adjustment function or adjustment mechanism for adaptation, even in the off-season, the automatic developing unit and drying unit are used in exactly the same way as in the off-season. The disadvantage is that there is considerable waste in the amount of each processing liquid used in the developing device and the cost of driving power, resulting in a lack of economic efficiency.

This is one of the countermeasures that the applicant for this utility model registration started to improve.
The technology described in the specification attached to the application No. 87322 (Sho 58-190648) and the subsequent desire for improvement are evident in the application No. 58-31114 (Japanese Utility Model Application No. 58-31114) filed on the same date as this application. As stated in the specification attached to the application of Japanese Utility Model Application No. 59-138853) and Japanese Patent Application No. 58-35241 (Japanese Patent Application No. 59-162550), one required processing liquid tank in an automatic developing device is used as a standard. Each processing liquid tank is divided into several processing liquid tanks along with other processing liquid tanks by dividing walls, and each processing liquid tank is used as is during the season, and only one of the divided chambers is used as its own during the off-season. At the same time as using it as a processing liquid tank, we developed a technology that slowed down the conveyance speed of photographic light-sensitive materials so that the same processing effect could be obtained both in season and off-season. When used as a device, we have achieved some results, but we have installed this automatic developing device in series with a drying device, making this automatic developing device part of the automatic developing device, and replacing the conventional drying device with If the drying unit is used as is, and this is used as an automatic processor that performs all processes from development to drying, the drying process in the drying unit during the off-season will be excessive. , which tended to be a major factor in deteriorating the processing effect on photographic materials.

Therefore, following the improvement of the automatic developing device for the automatic processor configuration, the applicant for this utility model registration has begun to improve the drying device for the automatic processor configuration, and as a drying device for the automatic processor configuration, It has become possible to provide an automatic developing machine that has an extremely simple configuration, can be switched between season and off-season with extremely simple operations, and is equipped with a drying device that does not cause deterioration in processing effectiveness. The present invention will hereinafter be referred to as Utility Model Application No. 87322, filed earlier by the applicant for utility model registration, and Utility Model Application No. 31114, 1987, filed separately by the applicant for utility model registration on the same date as this application.

Since the automatic developing machine according to the present invention is constructed as described above, its usage and function will be explained separately during the season, that is, during the season and during the off-season.

First, during the season, the required processing liquid is supplied to each chamber A ₁₁ , B ₁₁ , A ₁₂ , B ₁₂ , ... of each processing liquid tank of the processing liquid tank section 10, and the overflow pipe 19 ₁₁ with an on-off valve is , 19 ₁₂ , ...'s on-off valve is closed,

When the leader belts 31, 31 carrying the paper are run, the paper is subjected to a so-called development process in the processing liquid tank 10, and if necessary, the squeezed paper is passed through the opening 52 in the squeeze tank. The paper is conveyed into the drying unit Y through the dryer section Y, subjected to drying treatment, and then slowly cooled.The paper is conveyed together with the leader belts 31, 31 through the opening 62 into the paper take-out section Z. The pulleys 32 _o+y and 32 _o+y of the separation section are separated from the leader belts 31 and 31 and wound up at the winding section, but the leader belts 31 and 31 are separated from the leader belts 31 and 31 by the pulleys 36 ₁ and 36 for return. ₁ ,...,36 _o+

However, in this case, each of the empty chambers A ₁₁ , A ₁₂ , and
The pulleys and rollers used to guide the paper in A ₁₃ , ... had the drawback that the pretreatment liquid tended to adhere unevenly, leading to so-called uneven development.

Therefore, as shown by the chain line in Figure 2, the leader belt is attached to one of the empty chambers in each processing liquid tank.

Not only can papers No. 1 and 31 be used as they are without any processing, but uneven development is caused by passing the paper through chambers A ₁₁ , A ₁₂ , ... that do not contain processing liquid. You can wipe out the biggest cause of this.

Note that the conveyance mechanism 30 may be of a known type that conveys the photosensitive material using both side edges, but in this case, the leader belt 3

As is clear from the above description, the automatic processing machine for photographic light-sensitive materials according to the present invention has each processing liquid tank to which each processing liquid for processing photographic light-sensitive materials is separately supplied by each processing liquid supply mechanism. an automatic developing device section which is arranged in a series and is equipped with a conveying mechanism for conveying the photographic light-sensitive material in a meandering manner through each of the processing liquid tanks and sequentially subjecting it to each treatment; The apparatus is connected to and installed in series with the conveyance mechanism of the automatic developing device section, and has a hole for carrying in the processed photosensitive material carried out from the automatic developing device section and for blowing out hot air for drying. An automatic developing machine for photographic light-sensitive materials comprising a drying device section equipped with a transport mechanism that transports the processed photographic light-sensitive material along an air duct having a large number of holes and dries the processed photographic light-sensitive material before the transport. Each of the processing liquid tanks in the automatic developing device section is based on the processing liquid tank in which processing takes a relatively long time and requires accuracy in this processing time, and other required The processing liquid chambers are divided at positions that do not interfere with the meandering process by dividing walls that are lower than the partition walls between the processing liquid tanks, and the conveyance mechanism is equipped with a means for processing both of the divided processing liquid chambers. A conveying speed variable mechanism unit is attached to make the time for processing the photographic light-sensitive material as a liquid tank the same as the time for processing the photographic light-sensitive material using only one of the processing liquid chambers as a processing liquid tank, and the drying device The conveyance speed of the conveyance mechanism in the automatic developing device section is synchronized with the conveyance speed of the conveyance mechanism of the automatic developing device section, and the air duct, which has many holes for blowing out hot air for drying, has holes for blowing out hot air for drying. By installing a hole closing member for blowing out hot air for drying, which increases or decreases the number of openings in direct proportion to the conveyance speed, a. All drying treatments can now be performed consistently.

(b) The processing liquid tank required in the automatic processing unit that performs so-called development processing on photographic light-sensitive materials is divided into two parts, and can be used during seasons when large quantities of photographic light-sensitive materials are required to be processed, and during seasons when large quantities of photographic light-sensitive materials are required to be processed. Since the processing solutions can be used separately during the off-season and off-season periods, each processing solution required for development processing can be consumed economically.

c At the same time, when developing during the season and off-season, the conveyance speed of the photographic light-sensitive material is changed so that the developing processing time is the same during both periods. The same development processing effect was obtained.

d In relation to b and c above, the conveyance speed of the photosensitive material in the drying device section is synchronized with the conveyance speed of the automatic developing device section, while the number of holes for blowing hot drying air in the air duct is directly proportional to the conveyance speed. As a result, the same drying effect can be economically obtained on the developed photographic material during both the season and the off-season.

e As a result of the above b, c, and d, the same photographic processing effect can be obtained both during the season and during the off-season.

It has now become possible to provide an automatic developing machine for photographic materials that exhibits excellent functions and effects such as the following.
