Description
【０００１】[0001]
本考案はマガジン等へ明室下で装填できるように、ロール状感光材料に遮光包 装を施した明室装填用ロール状感光材料に関するものである。 The present invention relates to a roll-shaped photosensitive material for light-chamber loading, in which a roll-shaped photosensitive material is light-shielded so that it can be loaded into a magazine or the like under a bright room.
【０００２】[0002]
スキャナー感材等のロール状感光材料は最上巻部に設けられた周面遮光部と側 面を遮光する側面遮光部により、完全に遮光されており、明室下でマガジンに装 填できるようになっている。マガジン内へ装填されたロール状感光材料は、周面 遮光部と一体になったリーダー部を引張ることによってマガジン内で遮光部が引 き裂かれ、マガジンのスリットから感光材料が引き出されるようになっている。 The roll-shaped photosensitive material such as the scanner sensitive material is completely shielded from light by the peripheral light-shielding portion provided on the uppermost winding portion and the side light-shielding portion that shields the side surface so that it can be loaded into the magazine under a bright room. Has become. With the roll-shaped photosensitive material loaded in the magazine, the light-shielding part is torn in the magazine by pulling the leader part integrated with the peripheral light-shielding part, and the photosensitive material is pulled out from the slit of the magazine. ing.
【０００３】 これらの明室装填用ロール状感光材料の遮光部の包装形態及び包装方法は実開 昭６０−１３３８６、同昭６０−１６７７９６、同平３−３７４４７、同平３− ４７５４７、特開平２−７２３４７号公報等に各種記載されている。The packaging form and packaging method of the light-shielding portion of the roll-shaped light-sensitive material for loading in a bright room are described in JP-A-60-13386, 60-1617796, 3-37447, 3-47547, and JP-A-3-47547. Various types are described in, for example, JP-A-2-72347.
【０００４】 前記遮光部の包装形態の１つは、周面遮光部と側面遮光部が１枚物で構成され ているため、マガジン内での遮光部破壊の条件を満足させなければならないこと 、及び１枚物で構成されているがゆえに、側面遮光部の折込時に生じる遮光シー トのダブツキ部分を折り曲げて重ね合わせなければならないこと等によって、遮 光部の材質は剛度が限定されていた。One of the packaging forms of the light-shielding portion is that the peripheral light-shielding portion and the side-face light-shielding portion are composed of one piece, so that the condition for breaking the light-shielding portion in the magazine must be satisfied. In addition, since the light shielding portion is made of a single piece, the rigidity of the material of the light shielding portion is limited due to the need to fold the overlapping portions of the light shielding sheet that occur when the side light shielding portion is folded and to overlap them.
【０００５】 もう１つの包装形態は周面遮光部と側面遮光部が別々の２枚物から構成されて いるが、従来から用いられている側面遮光部の材質は、紙、ラミネート紙、アル ミサンド紙等で、剛度が低くまた湿度の影響を受けやすく剛度が不安定であり、 満足のいくものではなかった。In another packaging form, the peripheral light-shielding portion and the side light-shielding portion are composed of two separate materials. The material of the side light-shielding portion that has been conventionally used is paper, laminated paper, aluminum sand. With paper, etc., the stiffness was low, and it was easily affected by humidity, and the stiffness was unstable, so it was not satisfactory.
【０００６】 このように側面遮光部の材質の剛度が不足した場合、ロール状感光材料が使用 され、消費されて、巻径が小さくなった時、側面遮光部がロール状感光材料側に たわみ、ロール状感光材料を引き出す際に、抵抗が大きくなったり、蛇行したり 、耳やぶれを起こしたり等の問題が発生した。When the rigidity of the material of the side light-shielding portion is insufficient, the roll-shaped photosensitive material is used and consumed, and when the winding diameter becomes small, the side light-shielding portion bends toward the roll-shaped photosensitive material side. When pulling out the rolled photosensitive material, there were problems such as increased resistance, meandering, and ears and blurring.
【０００７】 これらの問題を防止するために、特開平２−７２３４７号公報にロール状感光 材料側面と側面遮光部との間に皿状の環状部材を挿入するという提案がされてい るが、包装作業の効率が非常に悪く、コスト的にも好ましくなかった。In order to prevent these problems, Japanese Patent Application Laid-Open No. 2-72347 proposes to insert a dish-shaped annular member between the side surface of the roll-shaped photosensitive material and the side light-shielding section. The work efficiency was very poor and the cost was not favorable.

【００１０】 本考案における前記ロール状感光材料の側面部分に相対する側面遮光部の材質 について、前記した剛度不足から発生する諸問題を回避するため、本考案者らは 検討を重ねた結果、クラーク剛度（ＪＩＳ Ｐ８１４３）が６５以上の材質を使 用することが不可欠で、６５未満では前記した問題が発生することがわかった。In order to avoid the problems caused by the insufficient rigidity described above with respect to the material of the side light-shielding portion facing the side surface portion of the roll-shaped photosensitive material in the present invention, the inventors of the present invention have conducted extensive studies, and as a result, Clark It has been found that it is essential to use a material having a rigidity (JIS P8143) of 65 or more, and if it is less than 65, the above-mentioned problem occurs.
【００１１】 本考案において前記側面遮光部の材質のクラーク剛度は好ましくは７０以上で 、かかる材質は特に限定されないが、加工性、包装作業性、コストの面から薄層 で剛度の高いものが好ましく、また湿度依存性の小さいものがよい。これらの材 質として、高密度ポリエチレン、ポリプロピレン、ポリエステル等のプラスチッ クフィルムがあり、前記プラスチックフィルムを主体とした紙やアルミ箔との複 合材料が特に好ましく用いられる。当然これらの材質には遮光性が必要で、各種 遮光性物質を含有させることができるが、本考案は特に限定されない。In the present invention, the Clark rigidity of the material of the side light-shielding portion is preferably 70 or more, and such a material is not particularly limited, but a thin layer having a high rigidity is preferable in terms of workability, packaging workability, and cost. Also, it is preferable that the humidity dependence is small. As these materials, there are plastic films such as high-density polyethylene, polypropylene and polyester, and a composite material mainly composed of the plastic film and paper or aluminum foil is particularly preferably used. Of course, these materials need to have a light-shielding property, and various light-shielding substances can be contained, but the present invention is not particularly limited.
【００１２】 本考案における周面遮光部の材質は特に限定されないが、一般的にはリーダー 部を併ねており、遮光性を施したプラスチックフィルムまたはプラスチックフィ ルムと紙やアルミ箔との複合材料が用いられる。The material of the light-shielding portion of the peripheral surface in the present invention is not particularly limited, but generally, it also includes the leader portion, and is a composite material of a light-shielding plastic film or plastic film and paper or aluminum foil.
