Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic developing machine used for processing silver halide photographic materials such as color films, and more specifically,
For example, it can be used for so-called press use, where it is carried to the photo shooting site, processed on the spot, and then quickly transmitted by electronic means to the headquarters of a newspaper company. relates to a compact, simple, and portable automatic developing machine that is ideal for use at home as a hobby.
0Hz. The present invention relates to a method for easily changing the activity level of a processing step so that photographic performance is constant even if the conveyance speed changes according to a power frequency of 60 Hz, and a small automatic developing machine having means for using the method.

[Conventional technology]

When it comes to press photography, which values speed, if the shooting location is relatively close to the newspaper company's headquarters or bureau, the undeveloped 7-ilm itself is rushed from the location to the headquarters for processing.

However, when the shooting site is a remote location, it is common practice to develop the photographed film and then electronically transmit the image.

To develop such photographic film for press, you can use a nearby processing service facility such as a so-called mini lab, but such facilities may not necessarily be able to accept urgent processing. Furthermore, since it cannot be used at night, development is generally done manually, such as by so-called hand development or plate development.

In addition, in a small number of cases, commercially available automatic developing machines for press use are used, and small manual developing type developing machines for hobby use are used.

Generally, an AC power source is used as a power source for an automatic processor. Batteries can also be used as a power source, but they consume a lot of power, resulting in insufficient capacity, and voltage drop poses a problem for stable transportation. Furthermore, when using an AC power source, there are problems in selecting rotating equipment such as transformers and motors depending on the voltage and frequency of the AC power source. In a normal stationary type automatic developing machine, even if an AC motor is used, it will take 50.60 hours.
Although installing the Z sprocket was a hassle, it was enough to install it once.

However, for news reporting, there is a desire to freely carry the machine to various places, and for this purpose there are three conditions: small size, light weight, and simplicity.Although a voltage conversion transformer is not a major obstacle, a frequency conversion The frequency converter was extremely large and heavy, making it difficult to use. For this reason, if you replace the sprocket once every time the frequency changes to 50/60Hz as in the past, it will take a very long time and effort to replace it, so when you want to do it urgently, it is best to replace the sprocket once every time the frequency changes to 50/60Hz. When it comes to the press photos that are in question, they sometimes don't arrive in time. Furthermore, if the gears are not replaced enough, it is a matter of life and death if processing fails even if there is only one special bullet.

Even if you connect a 60Hz automatic processor to a 50Hz power supply, or conversely, connect a 50Hz automatic processor to a 60Hz power supply, you will not be able to obtain sufficient processing performance, and you may end up ruining an important product. Become.

Furthermore, simply by replacing the sprocket, it is not possible to determine whether the automatic developing machine to be processed is for 50 Hz or 60 Hz. You can distinguish them with stickers, etc., but it makes no sense at all if you forget to replace them.

Since rotating devices are driven by direct current, which is used in home breakers and video cameras, it is also possible to use direct current for conveyance in automatic processors, but all of these require small output and are not suitable for the conveyance motor of automatic processors. If direct current is used, heavy and large maintenance equipment is still required, and the three conditions requested by news organizations cannot be met. There is also a speed control motor that uses alternating current to control the rotation speed of rotating equipment, but when this motor is used at a frequency other than the set frequency, the accuracy of the rotation speed is poor. It is difficult to use for development processing where the processing time is strictly determined.

Therefore, a method is generally used in which the gears of an ordinary AC motor are changed to keep the rotational speed constant. However, replacing gears requires specialized technicians and tools, which does not meet the requirements of simple operation desired by news organizations. A structure similar to a car clutch or a bicycle gear exchanger with two types of gears could be considered, but it would still be difficult to meet the requirements of compact size and light weight.

[Problem to be solved by the invention]

Conventional photo-processing machines on the market are relatively large, so they require a special vehicle such as a truck or van to transport them to the shooting site, and there are still many manual operations and the processing time is long. For this reason, it has not become widespread. In addition, since most of the small developing machines for hobby use are operated manually, they are no different from manual development such as so-called plate development, and processing requires skill, so they are hardly used.

For this reason, among the press, there are two main requirements: ■ It must be small and lightweight and convenient to carry, and preferably it can be carried by a person without the need for a small passenger car; ■ It must be easy to transport the film and process liquid. Processes such as handling, processing temperature adjustment, and drying are automatically controlled, so no experienced skills are required for operation; ■ Processing performance is good and stable; ■ Processing time is fast; ■ There are few malfunctions. The emergence of a compact automatic developing machine for press use that satisfies the requirements of , light maintenance, and other requirements has been awaited.

The present invention was completed as part of research into a compact automatic processor suitable for press or hobby use that satisfies the above-mentioned requirements. The objective is to simplify the handling of changes in the power supply frequency so that it can be carried and developed anywhere in the world.

Therefore, an object of the present invention is to provide a compact automatic developing machine for photographic light-sensitive materials and a processing method that provides stable photographic processing performance regardless of the power frequency of the power source used. It is an object of the present invention to provide a small-sized automatic developing machine for photographic light-sensitive materials and a processing method that can easily determine which frequency the frequency setting of the small-sized automatic developing machine is set for.

The main purpose of the present invention is to clarify a compact automatic developing machine for press or hobby use that solves the problems mentioned above.Other objects and benefits of the present invention can be found in the following description or attached. It will be clear from the drawing.

[Means to solve the problem]

A feature of the compact automatic processor of the present invention that solves the above-mentioned problems is that the rotation speed of the AC motor changes depending on the power frequency of the place where the automatic processor is used, that is, the conveyance speed of the photosensitive material changes (the processing time of the photosensitive material changes). In order to absorb the changes (changes) and stabilize the photographic processing performance, it is achieved by easy means, and for that purpose, the activity of the processing process can be changed by changing the processing temperature, changing the processing solution, etc. (2) It is obtained by a method and means of changing the stirring effect of the processing liquid.

〔Example〕

Next, the present invention having the above characteristics will be explained as a specific automatic developing machine.

1 to 3 are perspective views of an automatic processor to which the present invention is applied. Although not shown, the outer frame of this device includes a shoulder strap or handle for transportation. is available.

In the figure, reference numeral 10 designates a main body frame that houses a processing tank, etc., which will be described later, and a frame whose part is a side wall of the processing tank. It is maintained in a light-shielded state by the substrates (bottom plates) of the set section, the cassette/film intake section, and the electrical equipment operation section, and is further maintained in a light-shielded state by the lids 1k and 12.

The main body frame 10 and lid bodies 11 and 12 are made of a resin material or a light metal material to reduce weight.

In the illustrated automatic developing machine, in order to further reduce the weight, the main body frame 10 itself forms the processing tank frame, so the main body frame 10 is made of a chemical-resistant, opaque, light-shielding material. It is shaped with Gokai resin material.

The lid l1 is for sealing a film setting section A, which will be described later, and the lid l2 is for sealing a film taking-in section B.

The number of films set may be one as shown in FIG. 2, or two may be processed simultaneously as shown in FIG. 2B.

Note that the lids 11 and 12 may be configured as a single lid.

The lid l1 has its base attached to the substrate on which the 7 illuminant part A is arranged by a hinge mechanism, and can be opened upward at a certain angle via this hinge mechanism, and can be opened in the closed state. tightening means for the maintenance of
3 is fixed to the upper end of the main body frame IO.

As shown in FIG. 2, the film 30 to be processed is stored in the cassette 3l and is placed in the 7ilmset/private part A located on the top of the substrate (inner lid) 20.
cents.

Usually, a small amount of the leading end of the photographed film 30 remains outside the film drawer opening of the cartridge 3l, so the film leader 32 is attached to the leading end and then set in the film setting section A.

At this time, the film leader 32 is pushed in slightly so that its leading end engages with a take-in roller of a film take-in section B, which will be described later.

Once the film 30 has been set and the lid 11 is closed to shield the interior from light, a start switch (not shown) is pressed, and the film leader 32 is first taken into the film loading section B of the film transport system.

When a certain amount of the film 30 is taken in and the end of the film 30 is detected, the cutter 40 is operated to remove the film 3.
Near the end of 0 was cut off, and 7 ilm 30 became Patrone 3.
1 and transported to a processing tank.

The cutter 40 cuts from an upper movable blade and a lower fixed blade,
The movable blade, which rotates around the base end, is operated by the driving force of a motor or solenoid.
Other types or shapes of kanota may also be used.

The 7 films 30 taken into the transport system from the film take-in section B are pulled by a film leader 32 that engages with a pinion or the like of the transport system, and are developed while being transported through the processing section C along a predetermined transport route. Main frame 10
Four people are placed in the drying section D, which is located outside the drying section, and the drying process is carried out automatically.

Note that instead of providing a drying section D for drying the film 30 discharged from the processing section C, the installation position of the drying section D is used as a mere exit, and a member for receiving the undried film 30 is prepared. The present invention also includes a mode in which the film 30 is dried by, for example, so-called hanger drying or manually dried with a dryer or the like.

The substrate (processing tank M) 20 on which the film setting section A and the film taking-in section B are arranged is placed on the upper part of the main body frame 10, and its base is fixed to the main body frame IO via a hinge mechanism. Since the main body frame 10 itself forms a processing tank, when the substrate 20 is opened via the hinge mechanism, the upper part of the processing section C is released. Note that the hinge mechanism may not be provided and the entire board 20 may be removed from the main body frame IO.

Next, the specific structure of the processing section C applied to the automatic developing machine of the present invention will be explained. setting the time,
etc. are not limited to those described below, but there are various variations for the purpose of improving processing performance and shortening processing time, and in relation to the composition of processing liquid, etc. Which of them is selected is not an absolute limiting factor for the automatic processor to which the present invention is applicable.

As shown in Figure 2, the main body frame 1O, which is the basic frame for forming the processing section C, is a divided tank with a bottom made of opaque light-shielding vinyl chloride synthetic resin material. be shaped. In the drawing, the gaps formed on both sides of each tank are a part where a drive gear of a film conveyance system, etc. are arranged, and a part where a temperature control heater, a liquid level sensor, a temperature sensor, etc. are arranged.

As shown in FIG. 2, a transport rack 50 is inserted into each processing tank from above, and is engaged with a cut arrow provided at the bottom of each tank, and at the same time, the lower part is fixed. By engaging the positioning pin at the top of the transport rack with the notch provided at the top of each processing tank, the transport rack is correctly installed in the processing tank.

The size of the transport rack 50 corresponds to the depth of the processing tank. In other words, the length of the conveyance path is defined according to the length of the processing time, and the length of the conveyance path is determined by the length of the conveyance rack 50.
It is defined by the size of the tank or the depth of the treatment tank.

As shown in FIG.
．． 51 , a drive system for driving this conveyance roller group 52 , and a support member 51 .
It has a stirring means separated from a stirring member 53 disposed in an intermediate region of the stirring member 51 and a drive system 54 for driving the stirring member 53.

The stirring member 53 includes a base plate 53A and a wing member 53B that engage with a long hole 55 provided in a support member 51.51, and is rotatably pivoted at an end of the base plate 53A at an I location and at other locations. A crank disk 54B is rotatably fixed to the side surface of the support member 51 and driven by a drive gear 54C.
The link 54A is rotatably fixed to the end face of the link 54A.

The drive system 54 of the stirring means is connected to the support member 51 of the transport rack 50.
．． The support member 51 is disposed on the outer surface of one of the support members 5l, and is linked to a drive transmission means disposed on the outer surface of the other support member 5l.

As shown by arrows in FIGS. 2 and 3, the 7-ilm 30 enters the transport rank 50 through the entrance roller, is guided by a group of transport rollers, is ejected from the exit roller, and is transferred to the next transport rack. It will be relocated. The film 30 is transported to a transport rack 50
Both ends thereof are engaged with conveyance rollers, and the emulsion is conveyed with the emulsion surfaces facing each other, and the stirring member 53 is located in the space in the middle.

In the case of a conveyance method in which a leader 32 is attached to the leading end of the film 30 and the seven films 30 are conveyed by being pulled by the leading leader 32, the side ends of the seven films 30 are engaged with conveyance rollers. You don't have to. However, in such a transport mode, the film 30 is
If the emulsion sag occurs, there is a risk that the emulsion surface will come into contact with the blade members 53B of the stirring member 53 and damage the emulsion surface, so it is desirable to provide a guide plate or the like to regulate the preferred conveyance path. In this way, if the conveyance path of the film 30 is kept constant, the vertical movement of the stirring member 53 is regulated by the long holes 55 provided in the supporting members 51 and 51, so that the end face of the wing member 53B and the film 30 are regulated. It is safe even if the distance is close. In order to further enhance the stirring effect of the processing liquid, it is preferable to make the distance between them as close as possible, and although it depends on the size of the processing tank and the speed of the vertical reciprocating motion, it is preferably about 50 mm or less.

In addition, in the above explanation, the number of films set is that they are processed one by one in a single row as shown in Figure 2.
As shown in the figure, it is also possible to simultaneously process two lines in two rows. In this way, it is possible to simultaneously process L pieces in each column by forming a plurality of columns. In this case, the base body 20B, film leader 32B, and cutter 40B have slightly larger dimensions than in the case of a single row.

Examples of the composition of the processing liquid, the structure of the processing tank, the processing time and the processing temperature used in the automatic processor of the present invention are as follows.

(Example 1) A mode in which the developing processing method of the present invention having the above-mentioned characteristics is carried out using an automatic developing machine to be described later will be described below.

In the aspect of this first embodiment, the photographic material to be processed is a non-gauge film, and the composition of the processing liquid used and the structure of the processing tank are as follows.

Note that this condition is an illustrative one applied to the first embodiment, and is not intended to limit the scope of the present invention, similar to the conditions of other embodiments described later.

The test was conducted using a small automatic developing machine shown in FIG. Further, in Examples 1 to 4, care was taken to ensure that stirring remained constant even if the power frequency changed.

The table below shows the results of measuring the D max portion of Konica Color G X 400 treated in the above experiment using PDA65.

It should be noted that the D max values in the standard treatment for each of the above-mentioned colors other than Konica Color G

From the results in Table I, the automatic processor for 55Hz settings was set to 50
When processing is performed by changing the set temperature from 6011z for Hz, and 50Hz for 60Hz, 60Hz for 50Hz
When processing was carried out by changing the set temperature for each S, good results were obtained with almost no change in D max.

If the standard processing is set at 50 Hz and used with a 60 Hz power supply, the processing temperature must be changed significantly.

In order to use a developing machine set for standard processing at 50 Hz for 60 Hz, the temperature must be set to 42-44° C., which is undesirable because the amount of evaporation increases. If you control the temperature for a long time,
This is not preferable because the processing tank capacity is small.

Furthermore, if 60Hz is set as the standard treatment, the processing time will increase by 20% when using 50Hz, which not only impairs speed, but also increases the degree of membrane swelling and makes it difficult to dry. I don't like it next door.

(Example 2) The concentration ratio of the CD prescription of the standard treatment of Example 1 was changed to correspond to the change in treatment time due to the change in the power supply frequency while keeping the standard treatment settings. The 7ilm used was Konica Color GX400.

Changes in frequency can be accommodated even by changing the concentration ratio.

(Example 3) Change the CD-4 concentration of the CD prescription during the standard processing in Example 1 and set the standard processing. Although the absolute values were different, almost the same trends were obtained.

Even if the pH of the CD is changed, it is possible to cope with changes in processing time due to changes in the power supply frequency.

(Example 4) The pH of the CD formulation during the standard treatment of Example 1 was changed to respond to changes in the power supply frequency while maintaining the standard treatment settings. The film used was GX400.

Even with films other than GX400 used in the examples, [)m
Although the absolute value of ax was different, almost the same feelings were obtained.

Even if the pH of the CD is changed, it is possible to cope with changes in processing time due to changes in the power supply frequency.

(Example 5) The stirring intensity of the CD treatment tank of Example 1 was varied.

The gear ratio of the stirring gear of the rack used in FIG. 3 of the apparatus used in FIG.

When an AC motor is used as the stirring driving force of the automatic processor, the stirring speed changes as the power supply frequency changes. That is, when comparing the same automatic processor, when used at a 60 Hz frequency, the rotation speed of the rotary device is 1.2 times that of when used at a 50 Hz frequency, and the stirring speed (stirring effect) also increases.

If the liquid composition of the CD processing solution is the same, the processing time will vary due to variations in the power supply frequency. This variation is caused by low frequency (50H
z) to a high frequency (60 Hz) appears as a variation in which the processing time becomes 1/1.2.

As mentioned above, the small-sized automatic developing machine shown in FIGS. 1 to 3 employs a blade agitation method within the transport rack, and the blade agitation speed was varied by changing gears. The composition of the processing solution used in the test is as shown in Example 1, and the CD processing time was 3'l5'', CD
