するものである。Detailed Description of the Invention [Industrial Application Field] The present invention is a method for processing light-sensitive sheet materials such as sheet-shaped X-ray photographic films, lithographic films, photographic papers, PS plates, photosensitive resin films, etc. The present invention relates to a buffer sheet body used in a magazine fed by a suction mechanism and a photosensitive sheet package using this buffer sheet body. In particular, it relates to a buffer sheet body and a photosensitive sheet package used in a system for loading sheet-shaped X-ray film, lithographic film, etc. into a photographing device, an image recording device, etc. in a bright room. Among these, we propose a packaging body particularly suitable for sheet-shaped infrared-sensitive films.

であった。このため真空ポンプ等の破損を防止する種々
の提案がなされていた。Conventionally, in order to feed the photosensitive sheets stored in a magazine, a vacuum suction mechanism was used to suction and take out the photosensitive sheets one by one. However, in this method, the suction cup continues to suction the bottom of the magazine even when the photosensitive sheet is used up, causing damage to the vacuum pump and the like provided in the suction system. For this reason, various proposals have been made to prevent damage to vacuum pumps and the like.

空ポンプ等の破損を防止するものである。For example, there was a sheet photosensitive material storage magazine proposed in Utility Model Application Publication No. 50-127378. This magazine has a groove-like recess for air leakage that does not penetrate the bottom of the magazine at the position where the suction cup contacts the bottom of the magazine, so that air can flow into the suction system and the suction system's vacuum pump, etc. This is to prevent damage.

This magazine is made of a member that has relatively fine irregularities on its surface or a member that is flocked on its surface, the size of which is not completely included in the suction surface of the suction cup, at the position where the suction cup touches the bottom of the magazine. It is equipped with intake air leakage means.

ガジンの製作に工数がかかり高価となり、また溝状凹部
のあとが感光性シートに濃度むらとして発生するだけで
なく擦傷も発生するという問題があった。[Problems to be Solved by the Invention] However, the magazine provided with the first groove-like recess requires a lot of man-hours to manufacture the magazine, making it expensive, and the marks of the groove-like recess may cause density unevenness on the photosensitive sheet. There was a problem in that not only scratches but also scratches were generated.

接着剤がはみ出して感光性シートに付着したり、残溜溶
剤や揮発成分等によるかぶりや感光度の増減等の問題点
があった。In magazines equipped with the second intake air leakage means, pressure buildup occurs on the photosensitive sheet due to the swelling of the intake air leakage means, and the intake air leakage means may peel off.
There were problems such as the adhesive extruding and adhering to the photosensitive sheet, fogging due to residual solvents and volatile components, and changes in photosensitivity.

ぶりの発生や板紙表面の繊維が離脱して感光性シートに
付着し現像阻害やスポット故障が発生した。In addition, when using these magazines, a protective cover made of paperboard or the like is used during the transportation process of the photosensitive sheets, and vibrations during transportation can cause friction fogging and scratches on the photosensitive sheets, and the paperboard may also be damaged. Fog occurred due to the moisture and gas inside, and fibers on the surface of the paperboard detached and adhered to the photosensitive sheet, causing development inhibition and spot failures.

う問題があった。In the case where the photosensitive sheet is stored in the magazine through the third perforated protective sheet, a highly rigid sheet such as paperboard or synthetic resin sheet is used as the protective sheet. There has been a problem in that fibers generated or separated from the surface and perforation debris generated from the perforated portions adhere to the photosensitive sheet, causing development inhibition and spot failures.
さらに、この保護あて紙は感光性シートの包装体におい
ても用いられているで、感光性シートの輸送中において

あった。Furthermore, since this protective paper is also used in packages for photosensitive sheets, there are problems such as pressure fogging caused by the perforation marks even during transportation of the photosensitive sheets.

に、真空ポンプの破損防止を保持しつつ感光性シートに
悪影響を与えず非常に好ましいことを見い出した。The inventors of the present invention have conducted extensive research to solve the above problems, and have developed a buffer sheet body that is separate from the protective sheet and is equipped with adsorbed air leakage means, which protects the photosensitive sheet and It has been found that this is very preferable since it does not adversely affect the photosensitive sheet while maintaining the prevention of damage to the vacuum pump.

なければならない。By the way, the buffer sheet body must be placed on the protective paper so that the suction air leakage means is in contact with the suction cup of the vacuum pump, and to perform this work, the suction air leakage means must be visually inspected in a bright room. You must check the location of the

ならず、極めて作業性の悪いものであった。However, working in a bright room like this
Since the photosensitive sheet is stored in a dark room, the number of work steps is increased and the manufacturing efficiency of the package is poor. Furthermore, even when working in a dark room, it is necessary to trace the surface of the buffer sheet body by hand to search for means for leaking adsorbed air, resulting in extremely poor workability.

外側に設けた保護あて紙とを有する感光性シート包装体
において、該緩衝シート体は吸着空気漏洩手段及び位置
合せ手段を設けたことを特徴として構成されている。Further, the photosensitive sheet package of the present invention includes a large number of stacked photosensitive sheets, a buffer sheet body that contacts at least one of the outermost sheets, and a protective sheet provided further outside of the sheet body. In the photosensitive sheet packaging body having a patch paper, the buffer sheet body is characterized by being provided with adsorption air leakage means and positioning means.
緩衝シート体は、感光性シートに接し、接触する感光性
シートに水分やガスや圧力や摩擦等によるかぶりを発生
させないためのものである。The buffer sheet body is in contact with the photosensitive sheet to prevent the contacting photosensitive sheet from fogging due to moisture, gas, pressure, friction, etc.
この緩衝シート体には位置合せ手段が設けられている。This buffer sheet body is provided with alignment means.
この位置合せ手段は、暗室において吸着空気漏洩手段を
正確に所定位置になるように緩衝。This positioning means buffers the suction air leakage means so that it is accurately in a predetermined position in a dark room.

に貫通孔又は凹陥部を設けたりする。This is for arranging the sheet body. That is, when the buffer sheet body is held in the hand, the position of the positioning means can be confirmed □ by touch. Therefore, the positioning means may be any means that can be confirmed by touch, and various sizes, shapes, and positions can be adopted. For example, a concave portion or a convex portion may be provided on the periphery near the corner, or a through hole or a concave portion may be provided near the corner.
前記、吸着空気漏洩手段は穿孔又は凹部で構成されてい

、三角形、正方形、長方形、花形、スリット形、星形。The adsorbed air leak means is composed of a perforation or a recess. This perforation may be completely contained within the suction surface of the suction cup if there is a space between the protective patch and the buffer sheet, but if the protective patch and the buffer sheet are fully adhered must not be completely contained within the suction surface, but must be partially located outside the suction surface. The shapes of the perforations are circular, triangular, square, rectangular, flower-shaped, slit-shaped, and star-shaped.
蛇行スリット形等あらゆる形状が使用可能である。Any shape can be used, such as a meandering slit shape.

ればよい。Like the perforation, the shape of the recess does not matter, but it must be formed so that it is not completely contained within the suction surface of the suction cup, but is partially located outside the suction surface. In short, whether it is a perforation or a recess, it is sufficient that the suction cup is configured to communicate with the atmosphere through some route and the atmosphere can flow into the suction cup.
