Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for cleaning a photosensitive material conveying path of a processor for printing and developing a photograph and a cleaning method therefor, and more specifically to a dry photosensitive material conveying path of a processor, for example, a negative in an auto negative mask unit. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for cleaning a film transport path and the like.

[0002]

2. Description of the Related Art For each member constituting a photosensitive material conveying path of a photographic processor, for example, a negative film conveying path in an auto negative mask unit, that is, a guide plate, a guide roller, a glass plate, a perforation detecting hole attached to the member, etc. The attached dust and dirt not only damage the negative film to be sent, but also impede the transmission of an appropriate amount of light to reduce print quality, and prevent accurate detection of various data held by the film, resulting in malfunction. It had an adverse effect.

As a tool for cleaning such dust and dirt adhering to the conveying path of the negative film, a water-containing band-like cleaning leader formed by compressing and heating synthetic fibers has been used up to now, and a part of the cleaning leader is cleaned. The dust was wiped off by impregnating the liquid for use with the liquid and passing it through the film transport path.

However, the conventional cleaning tools are non-woven sheets made of synthetic fibers. Therefore, although the cleaning tools have an appropriate level of elasticity, the liquid-impregnated portion is liable to become weak because the liquid permeates the entire front and back surfaces. As described above, the film is easily bent, and it becomes difficult to obtain smooth feeding by keeping the film feeding path in motion. In particular, the cleaning tool that was once impregnated with the liquid became extremely weak, and could not endure being washed with water and used again, so it was destined to be discarded.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to fundamentally improve the structure of a cleaning tool and form it so as to semi-permanently maintain a proper rigidity of the tool itself, thereby ensuring a smooth and reliable transport path. It is intended to improve the workability and durability as a cleaning tool for a photosensitive material conveying path in a photographic processor, such as ensuring transport and semi-permanent rigidity that enables washing with water to realize repeated use.

[0006]

In order to achieve the above object, the present invention provides a cleaning tool composed of a band-shaped sheet having water content and flexibility, which is made of a flexible and relatively rigid material. Provided is a cleaning tool in which a surface material made of a material having a function of impregnating liquid is integrally pressure-bonded to both surfaces of a belt-shaped core material to form a belt-shaped sheet, and a cleaning liquid is applied to a leading end portion of the belt-shaped sheet. A cleaning method characterized by wiping off the dirt in the conveying path between the liquid-impregnated part and the non-impregnated part of the belt-shaped sheet that is conveyed while maintaining a rigid and regular shape by impregnating and feeding the photosensitive material conveying path of the processor. Suggest a method.

[0007]

[Function] The surface material that has become weak due to the impregnation of the cleaning liquid is reinforced strongly by the rigidity of the core material and maintains its original shape without breaking the waist. There is no occurrence of wiping and clogging during feeding, and, in combination with the tensile strength of the core material, no cleaning troubles such as tearing during impregnation conveyance occur.

After cleaning, dust and dirt adhering to the surface material can be washed off with the impregnated cleaning liquid with water, and the regular shape of the cleaning tool can be maintained without breaking due to the rigidity of the core material. Hold.

[0009]

Embodiments of a cleaning tool for a photographic processor and a method therefor according to the present invention will be described with reference to the drawings. 1 and 2 are explanatory views of a tool for cleaning a photosensitive material conveying path according to the present invention, in which (1) shows a belt-shaped sheet, which is a thin belt-shaped medium made of a flexible and relatively rigid material. It has a hybrid structure in which a core material (2) and thin strip-shaped surface materials (3) and (3) made of a water-containing material are integrally pressure-bonded on both front and back surfaces thereof.

An example of the strip-shaped sheet (1) will be explained. Innumerable bubbles made of ester polyurethane are formed on both front and back surfaces of a non-hydrous flexible core material (2) made of polyethylene terephthalate (PET). A strip-shaped sheet (1) having a thickness of 0.4 mm, in which a flexible foam material having the above is attached, compression-heated, and integrally pressure-bonded, and surface materials (3) and (3) having innumerable small cavities on both sides are integrally adhered ) Is formed. The size of the strip-shaped sheet (1) differs depending on the size of the photosensitive material conveying path (negative mask, etc.) of the photographic processing machine. For example, a 35 mm film conveying path has a width of 34.5 mm and a length of 485 mm. .

Surface material (3) made of this flexible foam material
Is advantageous in that it is rich in water content and does not fluff on the surface due to friction caused by feeding, and that it does not break up into dust that adversely affects printing.

Next, a cleaning method using the strip-shaped sheet (1) will be described based on the above-mentioned embodiment. Alcoholic liquid or water or other cleaning liquid is applied to the leading end portion (1a) of the strip-shaped sheet (1). Fully impregnated with a length of about 100 mm
Forming a wetting zone (4) with a length of 3
A drying zone (5) for removing moisture of about 85 mm is formed.

The impregnated cleaning liquid is an uneven surface formed by the numerous cavities having a water-containing and aeration function formed on the surface of the surface material (3) (3) of the hybrid structure, increasing the surface tension and being retained in a large amount. Therefore, it can be sufficiently impregnated, and the rigidity of the core material (2) maintains the normal shape without breaking the waist to ensure smooth feeding, and prevents fuzzing during feeding to prevent generation of dust. It is effective in that

The impregnated strip-shaped sheet (1) is fed into a strip-shaped photosensitive material conveying path of a photographic processor, guided in the same manner as the photosensitive material and sequentially conveyed by rollers, and in the wet zone (4). The cleaning liquid that dissolves dust and dirt that has adhered to the guide plate, guide rollers, glass plate, perforation detection holes, etc. of the auto negative mask unit is wiped and sent by the cleaning and washing action, and the long drying zone that follows (5) By sequentially wiping the cleaning liquid adhering to each part of the transport path and sending it, the transport path is cleanly cleaned and completely dehumidified.

[0015]

The cleaning tool of the present invention has the structure described above, and a long strip-shaped sheet having a width corresponding to the width of the photosensitive material conveying path of the photographic processor is used as the cleaning tool. It is characterized in that it is formed in a hybrid structure of a core material made of a certain material and a surface material made of a water-containing material that is integrally pressure-bonded to the surface of the core material. It is possible to supplement the weakness caused by the impregnation of the cleaning liquid by integrally reinforcing it, and to increase the tensile strength to prevent tearing during the impregnation conveyance and to accurately feed it for efficient cleaning.

In particular, the shape-retaining force due to the toughness of the core material,
The cost of cleaning maintenance can be reduced because the entire band-shaped sheet can be prevented from being bent or deformed to maintain its water-retaining function even after being washed with water to wash away cleaning liquids and stains remaining on the surface material after use, and it can withstand repeated cleaning use. Contribute to.

In the cleaning method in which the cleaning liquid is impregnated into the leading end portion of the strip-shaped sheet having a hybrid structure and the strip-shaped sheet is conveyed, the strip-shaped sheet does not bend and does not cause a jam in the conveyance. And the like can be easily and surely removed to improve the cleaning efficiency, and the cleaning cost can be reduced by enabling reuse.
