本発明は殖版機の改良に関し、特に感材と原稿を感材ホ
ルダと原稿ホルダの間に挟持する構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in printing presses, and particularly to a structure for holding a photosensitive material and a document between a photosensitive material holder and a document holder.
従来の一般形殖版機は、殖版機本体に感材ホルダと原稿
ホルダを回動自在に支持し、同感材ホルダと原稿ホルダ
の間に感材と原稿を重ね合せて構成し、同感材ホルダと
原稿ホルダの間を真空にした後、原稿側から露光焼付す
ることが行われている。Conventional printing plate machines have a structure in which a photosensitive material holder and a document holder are rotatably supported in the printing plate main body, and the photosensitive material and the document are overlapped between the photosensitive material holder and the document holder. After creating a vacuum between the holder and the document holder, exposure printing is performed from the document side.
また同殖版機において、感材ホルダと感材を吸着支持す
るには従来は例えば第７図に示すように、箱形に構成し
た感材ｈルダ１の上面に例えばロンリュウム材で構成し
てなる弾性板２を施設し、さらに同弾性板２の吸着側の
表面の所定範囲に吸気溝３を構成し、同吸気溝３の一部
に真空ポンプに接続してなる吸気パイプ４を配設し、同
吸気パイプ４により吸気溝３の空気を吸引し感材５を感
材ホルダ１の弾性板２に吸引するように構成しである。In addition, in the same plate printing machine, in order to adsorb and support the light-sensitive material holder and the light-sensitive material, conventionally, as shown in FIG. Further, an intake groove 3 is formed in a predetermined range of the suction side surface of the elastic plate 2, and an intake pipe 4 connected to a vacuum pump is arranged in a part of the intake groove 3. The structure is such that the air in the intake groove 3 is sucked through the intake pipe 4, and the sensitive material 5 is sucked into the elastic plate 2 of the sensitive material holder 1.
゛ ところで感材には多種のサイズのものがある。゛ By the way, there are various sizes of sensitive materials.
例えば縦と横の長さが、５５０Ｘ４５０，６５０ｘ５５
０．７２０ｘ６００．１０００ｘ８００゜１１５０ｘ９
５０．１３２０ｘ１０５０ミリメートル等のものがある
。For example, the length and width are 550x450, 650x55
0.720x600.1000x800゜1150x9
There are 50.1320 x 1050 mm, etc.
そこで弾性板に設ける吸気溝は最少のサイズの範囲内と
することが行われている。吸気溝の範囲より感材が小さ
いと空気がもれてしまい感材を吸着することができない
ためである。Therefore, the intake grooves provided in the elastic plate are designed to be within the minimum size range. This is because if the sensitive material is smaller than the range of the intake groove, air will leak and the sensitive material cannot be adsorbed.
しかし吸気溝の構成範囲と感材のサイズの差が大きいと
、感材の外周は吸引されないので感材ホルダに感材は確
実に吸引されない。また真空ポンプの真空度を高めると
、感材支持部が弾性材で構成されているので、吸気溝が
変形し、空気を遮断し、また感材が変形し原稿と密着し
なくなる欠点がある。However, if there is a large difference between the configuration range of the intake groove and the size of the photosensitive material, the outer periphery of the photosensitive material will not be suctioned, and the photosensitive material will not be reliably suctioned into the photosensitive material holder. Furthermore, when the degree of vacuum of the vacuum pump is increased, since the photosensitive material supporting portion is made of an elastic material, the suction grooves are deformed, blocking air, and the photosensitive material is deformed, making it no longer in close contact with the document.
本発明は上記の点に鑑み発明したものであって、感材の
大きさに合わせて、感材を感材ホルダに確実に吸引支持
することのできる殖版機を提供することを目的とする。The present invention was invented in view of the above points, and an object of the present invention is to provide a printing press that can reliably suction and support a photosensitive material to a photosensitive material holder according to the size of the photosensitive material. .
