Abstract

PROBLEM TO BE SOLVED: To improve rigidity of a cleaning leader and to improve workability, light-shielding property and frictional force by impregnating a synthetic fiber with a resin, antistatic agent and pigment. SOLUTION: The cleaning leader 20 consists of a synthetic fiber 30 of wefts 31 and warps 32 and a resin 40 which impregnates this fiber. The synthetic fiber 30 has excellent water absorptivity and water holding property, and a wet or dry cleaning method is selected according to the contamination state of a magnetic head. Since the synthetic fiber 30 has low rigidity and is difficult to be carried, the fiber is subjected to hardening treatment such as impregnation with an urethane, acryl or silicone resin or coating of a resin. The thickness of the resin 40 is specified to 1/4 of the thickness of the cleaning leader 20, and rigidity is controlled by controlling the amt. of the resin for impregnation. By impregnating the fiber with a resin, rigidity of the cleaning leader can be improved. And, by adding additives such as an antistatic agent and a pigment, workability, antistatic property, light-shielding property, and frictional force can be controlled and an additive merit such as coloring can be obtd.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a cleaning material for a photographic light-sensitive material processing device.

[0002]

2. Description of the Related Art In a transport path for transporting a photographic light-sensitive material such as a film in a photographic light-sensitive material processing apparatus, dust peeled off from the film is accumulated in the transport path while the film is repeatedly transported many times. Therefore, it adversely affects the transportation of the photographic light-sensitive material. In particular, in a film having a magnetic recording portion represented by an advanced photographic system, if the magnetic layer or the protective layer for protecting the magnetic layer peels off,
There is also a problem that this adheres to the magnetic head and the reading accuracy by the magnetic head deteriorates. For this reason, the film transport path and the magnetic heads and sensors arranged on the transport path are regularly cleaned. As such a cleaning material, it is used in a head cleaner disclosed in Japanese Utility Model Publication No. 63-38416 (known art 1) and a cleaning card disclosed in Japanese Patent Laid-Open No. 3-203806 (known art 2). Such nonwoven fabrics are known.

[0003]

By the way, the non-woven fabric has a self-dusting property that fibers constituting the non-woven fabric fall off even if it is used for a long period of time for cleaning, and good cleaning can be performed. There was a problem that it could not be done. Further, this non-woven fabric was suitable for a wet type, but was not suitable for a dry type. To address this problem, the present inventors have paid attention to synthetic fibers, which are materials different from non-woven fabrics. As this synthetic fiber, there is one known under the name of wiping cloth. This wiping cloth is characterized in that the amount of self-generated dust is extremely small. This feature also has the advantage that it can be used in both wet and dry systems. The wiping cloth can be used in applications such as a magneto-optical disk manufacturing process, a printed circuit board cleaning process, a contact lens manufacturing process, and the like. Found them.

However, although this wiping cloth is suitable for cleaning the photographic light-sensitive material processing equipment, it has a problem that it cannot pass through the conveyance path of the photographic light-sensitive material processing equipment because it has no rigidity. In particular, when cleaning the magnetic head of photographic light-sensitive material processing equipment, it is necessary to have rigidity that can withstand conveyance.In such a case, it is troublesome to bother to remove the magnetic head and wipe the dirt off with a cotton swab. It is not preferable.

An object of the present invention is to provide a cleaning material that can withstand conveyance in a photographic light-sensitive material processing device. Another object of the invention is to provide a cleaning material that can be used both wet and dry.

[0006]

A characteristic feature of the present invention for achieving the above object is that a synthetic fiber is cured by a resin. As a result, it is possible to obtain rigidity that can withstand the transportation of the photographic light-sensitive material processing equipment. Therefore,
Cleaning of the magnetic head can also be done without trouble. Further, if a wiping cloth having extremely low self-dusting property is selected as the synthetic fiber, the wet type and the dry type can be freely selected according to the degree of contamination of the magnetic head. Further, the impregnation with the resin brings about an advantage that the workability is improved. This makes it possible to process with a versatile Thomson blade instead of ultrasonic processing or heat cutting. this is,
It also reduces the processing cost when processing the cleaning material into a predetermined shape.

Although there are various curing methods and methods, it can be achieved, for example, by impregnating the synthetic fiber with a resin selected from urethane resins, acrylic resins and silicone resins. Additives can be added to the resin by such resin impregnation. There is also an advantage that various added values are generated by this additive. Examples of such additives include antistatic materials and pigments. By adding additives, antistatic property, light-shielding property, control of frictional force μ, and coloring can be performed.

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the photo printing apparatus 1 includes an exposure unit 100 that projects and exposes image information of the film 2 onto the photographic paper 3, a development processing unit 101 that develops the exposed photographic paper 3, and the operation of each unit. And a controller 102 for controlling. An operation console 103 for inputting various control instructions and a monitor 104 for displaying image information read by a scanner unit (not shown) are connected to the controller 102.

When the film 2 to be printed is inserted into the exposure section 100, the image information of the film 2 is read for each frame and the image information is sent to the controller 102. The controller 102 reads the read film 2
The exposure condition for each frame is determined based on the image information of.
Then, an image that would be obtained by projection exposure on the photographic printing paper 3 according to the determined exposure condition is simulated and displayed on the monitor 104.

The operator of the photoprinting apparatus 1 operates the monitor 104.
If an appropriate image is not obtained by looking at the display of, the operator can input the correction instruction of the determined exposure condition from the console 103,
The controller 102 corrects the exposure condition based on the correction instruction and determines the final exposure condition. Then, based on the determined exposure condition, the operation of each part of the exposure unit 100 is controlled to project and expose the image information of the film 2 on the photographic printing paper 3 pulled out from the photographic printing paper magazine 4. The exposed photographic printing paper 3 is conveyed to the development processing section 101 and subjected to development processing, and is discharged in a state of being cut into one piece corresponding to each frame of the film 2.

The configuration of each section will be described below. In the exposure unit 100, a film transport unit 5 for transporting and positioning the film 2, an exposure light source 6, and yellow, magenta, and cyan filters in and out of the exposure optical path cause irradiation light from the exposure light source 6. Light adjusting filter 7 for adjusting the color balance of the film, a mirror tunnel 8 for uniformly mixing the light whose color balance has been adjusted by the light adjusting filter 7, and a printing lens 9 for forming image information of the film 2 on the photographic paper 3 A shutter 10, a conveyance roller 11 for conveying the photographic printing paper 3, and
A motor 12 that drives the transport roller 11 is provided. The dimming filter 7 and the shutter 10 are the controller 1
02, and the position of each filter of the light control filter 7 and the opening time of the shutter 10, that is, the exposure time are controlled according to the exposure conditions determined by the controller 102. Further, the motor 12 conveys the photographic printing paper 3 in a frame-feed state under the control of the controller 102.

FIG. 2 shows detectors and the like provided on the transport path inside the film transport unit 5. The film transport unit 5 is an example of a photographic light-sensitive material processing device. In normal use, the film 2 is transported along the transport path, but when cleaning the transport path, the cleaning leader 20 is transported. On the transport path, transport rollers 50, 51, 52 for transporting the film 2 or the cleaning leader 20, a magnetic head 54 for reading magnetic information from the film 2, and a light emitter for reading information such as a latent image barcode from the film 2. An optical sensor 55 including a light receiving device and a mask 56 that defines an image area of the film 2 are provided. The film 2 and the cleaning leader 20 are conveyed in the direction of arrow A in FIG.
In addition, the conveyance is carried out by a motor (not shown)
It is performed by driving 1 and 52.

As shown in FIG. 2, the cleaning leader 20 is pulled out from the delivery side 22 that is wound around the delivery shaft 21 in a roll shape, and is wound up around the winding shaft 23 on the winding side 24 in a roll shape. .

Next, the material of the cleaning leader 20 will be described with reference to FIGS. FIG. 3 shows the arrow B in FIG.
It is an enlarged view of a part. The cleaning leader 20 includes a synthetic fiber 30 and a resin 40 impregnated in the synthetic fiber 30 (impregnation of the resin 40 will be described later). A specific example of the synthetic fiber 30 is Wiping Cloth (trade name: Zavina Minimax) manufactured by Kanebo Co., Ltd. This material has an extremely small amount of self-generated dust and has excellent cleaning performance compared to non-woven fabric. Further, it is excellent in water absorption and water retention, and either "wet" or "dry" can be selected according to the degree of contamination of the magnetic head. In addition, the amount of elution components such as residual ions is small, and since dirt is captured in the fiber, recontamination is extremely rare. Then, it is possible to wipe off even fine particles that cannot be completely cleaned by the conventional nonwoven fabric. Furthermore, since no abrasive material is used, the magnetic head 54
It is also possible to suppress wear of the magnetic head 54 when cleaning the magnetic head. Many advantages can be expected if such a synthetic fiber 30 is used for cleaning the inside of the film transport unit 5. However, since the synthetic fiber 30 itself has low rigidity, the cleaning leader 20 is composed of only the synthetic fiber 30. Then, it is difficult to convey the sheet in the form shown in FIG.

Therefore, as shown in FIG. 3, the synthetic resin 30 is subjected to a hardening treatment (hard finish processing) for imparting rigidity. As hard finishing, resin impregnation or resin coating is suitable here. The resin 40 to be impregnated is a fraction of the thickness of the cleaning leader 20, preferably about a quarter. By impregnating the resin 40, the cleaning leader 20 is formed with the cleaning surface 20a and the impregnation surface 20b that actually perform the cleaning action. The rigidity of the cleaning leader 20 can be adjusted by adjusting the amount of the resin 40 impregnated. However, it is necessary to prevent the resin 40 from seeping out to the cleaning surface 20a. FIG. 4 shows FIG. 3 in a form close to the actual one. Synthetic fiber 30 includes weft thread 31 and warp thread 32.
And consists of The resin 40 to be impregnated is typically urethane resin, acrylic resin, silicone resin, or the like.

By impregnating the resin 40, the synthetic fiber 3
In addition to improving the rigidity of the cleaning leader 20 without impairing the above-described advantages of 0, addition of an additive such as an antistatic material or a pigment to the resin 40 prevents the antistatic property, the light blocking effect, and the frictional force μ. There are additional benefits such as control and coloring. For example, by adding a black pigment, the appearance of the cleaning leader 20 can be finished in black, and the light-shielding property is improved. Furthermore, the impregnation with the resin 40 improves the workability. The cleaning leader 20 is formed in a long and slender shape like the film 2. In order to make the end face of the outer shape clean in order to obtain such a shape, heat cutting or ultrasonic processing is necessary if the synthetic fiber 30 that is not impregnated with the resin 40 is left as it is. However, when the resin 40 is impregnated to improve the rigidity, it is possible to perform processing with a Thomson blade having high versatility, and it is possible to reduce the processing cost.

Next, the raw yarn 60 used for the synthetic fiber 30.
The cross-sectional shape of is shown in FIG. This is the raw yarn 60 used for the above-mentioned product name Savina Minimax, and is called by the product name "Berima X". This yarn 6
0 is a 0.1 denier ultrafine fiber. FIG. 6 shows the principle of capturing the dirt 61. This raw yarn 60
Can efficiently fit the surface of each detector and the like of the film transport unit 5 with polyester and nylon having a wedge-shaped cross section, and can reliably catch dirt.

Next, an example in which the cleaning leader 20 is housed in the cartridge 70 will be described with reference to FIGS. 7 and 8. The same members as those in FIG. 2 are given the same numbers. The cartridge 70 is the same as the one for winding and storing the film 2. The outer shape of the cleaning leader 20 is a long shape similar to the film 2, and the width dimension thereof is the same. Of course, they may have the same shape. The length of the cleaning leader 20 does not have to be the same as that of the film 2, and may be the length required for cleaning. The width dimension of the cleaning leader 20 may be smaller than that of the film 2. Cartridge 7
At 0, a hole 71 for driving the spool and an outlet 72 are provided.

Next, the operation of cleaning the transport path in the film transport unit 5 will be described with reference to FIG. First, the cartridge 70 in which the cleaning leader 20 is completely stored is set in the cartridge holding portion of the film transport unit 5. After the cartridge 70 is set, the spool of the cartridge 70 is rotated in the anti-winding direction by a predetermined start signal, and the tip of the cleaning leader 20 is pulled out from the outlet 72 (this operation is referred to as thrust operation). In order to perform this thrust operation, the cleaning leader 20 needs to have the same rigidity as the film 2, but since it is impregnated with the resin 40, the thrust operation can be performed without trouble. Also, the cartridge 7
Since there is a distance between the position where 0 is set and the magnetic head 54 to be particularly cleaned, at least the magnetic head 5
Although the cleaning leader 20 must be pulled out to the position where 4 is provided, since it is impregnated with the resin 40 to improve the rigidity, it can be smoothly conveyed.

Once the cleaning leader 20 is pulled out, it is carried in the carrying path by the carrying rollers 50, 51 and 52 to clean the magnetic head 54 and the like.
It should be noted that the cleaning leader 20 includes
May be completely withdrawn from. In this case, the transport rollers 50, 51, 52 are driven in the direction in which the cleaning leader 20 is stored in the cartridge 70. As a result, one end of the cleaning leader 20 can be attached to the spool of the cartridge 70 again (this is called an attach operation). The attaching operation can be performed smoothly because the rigidity is improved.
In this way, when cleaning is completed, the cleaning leader 20 is stored in the cartridge 70.

Further, another embodiment of the present invention will be described. (1) As the curing treatment, in addition to the impregnation with the resin 40, a sheet-like material formed of PET (polyethylene terephthalate) or the like may be attached to the synthetic resin 30 (indicated by reference numeral 40 in FIG. 3). The thing is a sheet.) (2) Although the film transport unit 5 has been described as an example of the photographic light-sensitive material processing device, it is not always necessary that the device is unitized. Further, it can be used for cleaning not only the film 2 but also the conveyance path of the printing paper 3. (3) It is not necessary to carry out the hardening treatment over the entire area of the cleaning leader 20 formed in a long shape, and the hardening treatment may be carried out only on the tip portion. This is because when the leading edge of the cleaning leader 20 is first fed into the film transport unit 5, rigidity is required.
