Description

[Detailed description of the invention]

"Industrial Use ￥'f" The present invention relates to an automatic developing machine used for processing silver halide photographic materials such as color films, which can be carried to photo shoot sites, for example, and used for photographic news reports. It is used for processing photographic film and quickly transmitting the film image to newspaper company headquarters, etc., or
More details 1. About the small and simple automatic developing machine that is ideal for use at home as a hobby. < relates to a compact automatic processor having an improved removable dryer unit. [Prior art] In news photography, where speed is important, if the shooting location is relatively close to the newspaper company's headquarters or branch office, the undeveloped film itself must be rushed from the location to the destination, such as the headquarters.
However, when the filming location is remote, it is common practice to develop the photographed film and then electronically transmit the image to the destination. To develop such photographic film for press, you can use a nearby processing facility such as a so-called mini lab, but such a facility does not necessarily require urgent processing. This is not always the case, and it is only available at night, so it is common to use manual methods such as so-called hand development or plate development. In addition, a small number of people use commercially available automatic developing machines for press use, or small manual developing machines for hobby use. Conventionally, devices called automatic processors have a built-in drying means, and a drying section consisting of a squeeze roller, a dryer, a heater, a blower, etc. is housed within the frame of the device. The drying section moves horizontally so that it is discharged from the equipment in a dry state. In addition, small manual development type automatic processing machines for hobby use are generally not equipped with a dryer, so films that have been wet with washing water or stabilizing liquid can be dried using a so-called hair dryer or a hair dryer. It is dried using a small dryer that is placed separately. [Invention tries to solve! ! ! The conventional automatic developing machines for press use on the market are relatively large, so transporting them to the shooting site does not require a special truck or a car such as a pan, and many parts still need to be operated manually. In addition, it has not become popular because it takes a long time to process. In addition, since most of the small hobby developing machines are operated manually, they are no different from manual development such as so-called plate development, and processing requires skill, so they are not used. Among those in the media, ■ It must be small and lightweight, making it convenient to carry. Preferably, it should be possible to carry it by one person without the need for a small passenger car; ■ It should be easy to disassemble the kita-banpu equipment, transport it, and assemble it on-site when using it; (■ Processes such as transporting the film, handling the processing liquid, adjusting the processing temperature, and drying are automatically controlled and do not require skilled skills to operate. ■ Processing performance is good and stable; There has been a long-awaited need for a small and simple automatic developing machine for press use that satisfies the following requirements: - fast processing time, - few malfunctions, and light maintenance burden. Considering the drying problem in the machine, if it takes a long time to dry using the dryer that is not provided in the machine, the slow drying speed will limit the drying speed, and the time from color development processing to stabilization or water washing will be reduced. There is no point in speeding up the process, and the drying part of an automatic processor is large and heavy; conversely, if the device does not have a drying section, manual drying is required, making it cumbersome. - There is a risk of damaging or staining the emulsion surface during the operation process.
There are many cases where it is sufficient to dry only a limited area, so in order to satisfy the demand for smaller and lighter parts,
It would be better to design the drying section as a removable external mounting type. ■ If the drying section is removable, there should be no problems with transportation or drying in the drying section; ■ The processing speed from color development to stabilization or washing should not be delayed; ■ A small simple dryer has been turned into a removable transport unit, and at the same time it has increased the speed of delivery. Eliminate problems such as jam rings; ■ Also, make it possible to use a commercially available hair dryer as a heat source for the dryer; It is pointed out that it is possible to do this, etc., as an issue. The present invention is based on the above-mentioned II! ! This product was completed after studying specific technical means to solve the problem, and aims to provide an optimal small and simple automatic developing machine that can be used on-site for press or hobby purposes. The main purpose is to clarify a compact automatic processor which solves the problem, and other objects and advantages of the present invention will become apparent from the following description and accompanying drawings. [Means for Solving the Problems] The above-mentioned objects of the present invention are: (1) to form a drying section into a unit and detachably attach it to the outside of the machine body; (1) The photographic material must be transported at the same speed as the material; (2) The photographic material must be transported in the drying section by the transport driving force of the developing machine; and/or (2) The emulsion surface of the photographic material must be on the inner wall of the drying section unit. Contact with JII2 may damage the emulsion surface.
We have provided a means to prevent problems such as jamming due to increased feeding resistance; ■ Increased drying speed, reduced the size of the drying device, and You can use a hair dryer etc.
This can also be achieved by adopting a structure in which the dryer can be easily attached and detached, and so on. [Example] First, prior to a detailed explanation of the present invention, an outline of an automatic developing machine for press use to which the present invention is applied will be explained with reference to FIGS. 1 to 3. Note that this automatic processor is designed to develop roll films, so automatic processors that develop disc films, photographic paper, etc. must have certain design specifications for the film setting section, transport system, etc. Requires changes. Further, the outer frame of this device is provided with a shoulder strap, a handle, etc. for carrying the device. In the figure, reference numeral 10 designates a main body frame that houses a processing tank, etc., which will be described later, and the upper part of this main body frame 10 is kept in a light-shielded state by lids 11 and 12 and a substrate (inner lid) 20 shown in FIG. has been done. The lid body 11 seals (shields light) the film set section A, which will be described later.
The lid body 12 is for sealing (light-shielding) the film intake section B. The lid body 11 has its base attached to the substrate 20 on which the film setting section A is arranged by a hinge mechanism,
It can be opened upward at a certain angle by a hinge mechanism, and the tightening means 1 is used to maintain the closed state.
3 is fixed to the upper end of the main body frame 10. The lid 12 shields the film intake section B from light.
Since there is no need to open the outside for maintenance, etc., we fix it with screws instead of using a hinge mechanism to access it. As shown in FIG. 2, the film 30 to be processed is set in the film setting section A prepared on the substrate (inner lid) 20 while being stored in the cartridge 31. Normally, a small amount of the leading edge of the film 30 that has been photographed remains outside the film drawer opening of the cartridge 31. (), attach the film leader 32 to the tip of the film, and then set it in the film storage section A. At this time, remove the film from the tip of the film leader 32 (described later).

[4-Push firmly so that it engages with the go-ra. When a certain amount of the film 30 is taken in and the end of the film 30 is detected, the cutter 40 is activated to remove the film 3.
The film 30 is cut near the end of the cartridge 3.
Separated from 1. Detection of the end of the film 30 is easy in the case of a commercially available film packaged with a cartridge, since the end of the film 30 or the spool shaft of the cartridge 31 is fixed, so it is easy to detect a sudden increase in tension when the film is taken in. This can also be done by detecting the movement of the pedestal to which the film tray 31 is fixed as it is pulled. The cutter 40 shown in FIG. 2 consists of a movable blade on the 7 side and a fixed blade on the lower side. Basically, it is important to decide whether the cutter is structured as such, and what type or shape of cutter to use (optional, one is available). The film is pulled by the holding film sorter 32 and transported through the processing section C according to the transport route shown in FIG. The film is introduced into the drying section and is automatically dried.
The board (middle fj) 20 on which 3 is placed is placed on the top of the main body knob 10 and is opened. Release 1]. The specific configuration of the I-pull line, burial and transport system in the processing section C will be determined based on the purpose of improving processing performance and shortening the processing time. It is also related to the composition of the liquid.
, , and 12: There are various variations, and the selection of these is not an absolute limiting factor of the present invention. Next, the structure of the drying section, which is the main feature of the present invention, will be specifically explained. Figure 3 shows the undeparted JJ]
This is a simplified diagram of this drying unit)-6
The mounting position 0 is the position shown as the drying section in FIGS. 1 and 2, that is, the position connected to the exit roller 51 of the processing section C on the side wall of the main body frame 1o. There are no limitations on how the drying section unit h60 is attached; for example, as shown in FIGS. Insertion method as shown in Figure 9, etc.
There are various ways of mounting, such as the 1-1 method of mounting using the eel hook 52 (not shown in Figure 14). Consideration should be given to sufficient light shielding so that light does not enter the storage area from the mounting position of the 60, and appropriate matching of the transport system to avoid problems in transport. It should be noted that, instead of directly accessing the drying unit 1, it is possible to reach the side wall of the processing tank through the attachment member L, so that the Z' handle of one sheet of film can be easily accessed. I can do something. Moreover, as shown in FIG. 14, the film 3
J: Sea urchin 17 may be discharged once into the row section and then introduced into the drying unit. The film 3o to be dried is dried in the drying section for 1 to 50 minutes.
There are various ways to transport the film 30 within the film, but a simple way is to prepare a guide plate 6I with a large number of through holes and transport the film 30 as shown in FIG. The output n1 of the processing section C - the drive force of the fuller 51)
This guide plate 614.' is arranged 17 as shown in Figs. φ) can also be manufactured. In the case of m-) shown in 114, the film 30I7',) emulsion 1 is on the upper side, and there are scratches etc. on the image surface. The guide plate 61 as shown in the figure may be used in a mode in which the film 3 is transported without a sorter reaching the edge for a long time. is effective for one fortune telling. In addition, the inner surface of the root 61, or the inner surface of the inlet part of the drying layer shown in FIG. 12,
In addition, in the state shown in FIG. 17Vi1 and FIG. 18, the wet film 30 is
In order to prevent the materials from coming into close contact with each other, it is preferable to form a large number of irregularities (see FIG. 15) or striped protrusions (see FIG. 16). The second mode of film transport in the drying section utilizes the driving force of the transport system in the processing section C by transmitting it to at least the transport roller at the exit of the drying section, as schematically shown in FIGS. 4 and 5. It is a mode. For example, a drive transmission roller in the drying section is provided at the entrance of the drying section unit 60, and when the drying section unit 60 is set, the drive transmission roller is brought into contact with the exit roller 51 of the processing section C. The conveyance speed in the drying section is configured to be the same as the conveyance speed in the processing section C. The conveyance power can be transmitted from the processing section to the drying section using a conventional power transmission mechanism 63 such as a gear or a belt (see FIG. 4). Note that the present invention also includes a mode in which a dedicated gear or the like for transmitting driving force to the transport system in the drying section unit 60 is prepared near the end of the transport system in the processing section C. Of course,
A system may be used in which the driving force is transmitted by a pulley (see No. 5-1) instead of the gear. In the third aspect, as shown in FIG.
A plurality of free rollers 62 are prepared in advance. In this embodiment as well, the sheet is transported at the same speed as the transport speed in the processing section C by the driving force of the exit roller 51 of the processing section C. The film leaving processing section C has a wet emulsion surface, so
It has the property of adhering to materials that come into contact with it, damaging the emulsion surface and causing transportation problems.
In order to convey the material within the drying unit, it is necessary to prevent the emulsion surface from coming into contact with the inner wall or the like. As a means for this purpose, a guide plate 6 is used so that the emulsion surface, especially the image surface, does not come into contact with each other.
1. Although the use of the free roller 62 has been described, as a further embodiment, as shown in FIG. There are ways to prevent this. Conversely, the film may be suctioned from below, or simply by bending and pulling the film toward the side other than the emulsion surface.
It is possible to prevent the emulsion surface from coming into contact with the inner wall. Such a method is particularly effective in the case of a transport method in which only 30 films are transported and processed without attaching a leader to the leading end of the film 30. It is also recommended to prepare a guide plate near the entrance of the drying unit 60, which has many irregularities (see Fig. 15) and protrusions (see Fig. 16) on its surface for adhesion of wet film. Effective in prevention. As a means for sending drying air into the drying section unit 60, it is possible to use a commercially available hair dryer or an industrial dryer used for thermal welding of organic materials, etc., for simple on-site use. In this case, the question of whether it is optimal or not is how to hold these dryers in the drying section unit 60, and this problem can be solved by the following structure. That is, for example, FIGS. 4 to 8 and 19
As shown in the figure, the dryer unit 60 is provided with an attachment port 64 having an inner diameter larger than the outer diameter of the air outlet of the dryer, and
An elastic pleat-like member is attached to the inner wall of this attachment hole 64, and the dryer outlet is held and fixed by deforming the pleat-like member. In addition to this lid-like member, methods for fixing the air outlet include a method of holding using a wire, a method of holding using a sponge-like member, a method of holding with a plate material having spring properties, Furthermore, arbitrary adjusting means such as a method of holding with screws may be employed (see patent application (1) filed on the same date). Drying air flowing at high speed along the surface of the photosensitive material to be dried is faster than blowing drying air onto the surface of the photosensitive material, which has the advantage of making the dryer smaller. There is. Further, as a power source for operating the heater and fan in the drying section unit 60, the automatic developing machine main body frame 10 is used.
A power outlet may be provided on the side of the machine, or an embodiment in which such a power supply connection terminal is not provided on the machine side of the machine is also included in the present invention. [Effects of the Invention] According to the present invention, the drying section and the main body of the automatic processor are configured to be detachable, and improvements have been made to the conveyance of the film in the drying section. Ru. still,
The present invention is applicable not only to negatives called films, but also to various photographic materials such as photographic paper called prints.
