本発明は例えばオフセット印刷或いは凸版印刷用の感光
性刷版の製版工程をご用いる自動露光機における版材の
位置決め機構に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate material positioning mechanism in an automatic exposure machine that uses a photosensitive printing plate making process for, for example, offset printing or letterpress printing.
一般に印刷用の刷版を作製するには、支持体上に感光層
を形成してなる版材を１版材載置盤」二に載置し、この
版材の感光層の上に例えば感光層がネガ型であれば、原
稿のネガフィルムを重ね、上方から露光を行い、感光層
のうち原稿の画線部に相当する部分にのみ光を当て、光
が当らなかった部分を後に溶出することで、凸状画線部
と凹状非画線部を有する刷版を得るようにしている。Generally, in order to produce a printing plate for printing, a plate material having a photosensitive layer formed on a support is placed on a plate material mounting plate, and a photosensitive layer is placed on the photosensitive layer of the plate material. If the layer is a negative type, the negative film of the original is stacked and exposed from above, exposing only the parts of the photosensitive layer that correspond to the image areas of the original, and the parts that were not exposed to light are eluted later. In this way, a printing plate having a convex image area and a concave non-image area is obtained.
このように、版材と原稿フィルムとを重ねて露光するた
め１版材と原稿フィルムの重ね合せがズしていると、そ
れだけ得られる刷版の面取りがくずれたり画線部がズし
たりする。このような刷版を用いて印刷した場合には印
刷物としての価値が損われる。In this way, since the plate material and the original film are overlapped and exposed, if the overlapping of one plate material and the original film is misaligned, the chamfer of the resulting printing plate will be distorted or the image area will be misaligned. . If such a printing plate is used for printing, the value of the printed matter will be lost.
そこで、露光を行うにあたっては１版拐と原稿フィルム

材の位置合せを行うことは、作業効率の低下ともなり、
且つその位置合せも常に正確に行われるとは限らない。Therefore, when performing exposure, it is necessary to accurately overlap the first printing plate and the original film, and conventionally, when exposing, a worker corrects the position of the printing plate on the mounting plate. . However, having workers align the plates each time they are exposed reduces work efficiency.
Moreover, the alignment is not always performed accurately.

たせるようにしたことをその要旨とする。In order to achieve this object, the present invention disposes first and second conveyance rollers below the upper surface of a plate mounting plate provided with a plate positioning member on the periphery. A part of the circumferential surface of the second conveyance roller is made to face upward through an opening formed on the upper surface of the plate material mounting plate, and the rotational direction of the first conveyance roller is made to substantially match the conveyance direction of the plate material, and the second conveyance roller is The gist is that the rotational direction of the roller is set at an angle of 1, for example approximately 45°, with the conveyance direction of the plate material.

できる等多くの効果を発揮する。As explained above, according to the present invention, a plate positioning member is provided at the peripheral edge of the plate mounting board disposed in the exposure section of an automatic exposure machine, and on the other hand, the plate mounting board ζ is An opening is formed through which a first conveyance roller that rotates in a direction that substantially coincides with the conveyance direction of the plate material and a second conveyance roller that rotates at an angle to the conveyance direction of the plate material face, and the plate material is transferred onto the plate placement plate. Since the plate material is pressed against the positioning surface, C
Therefore, when the negative film of the original document is later superimposed on the plate material, misalignment between the negative film and the plate material can be prevented. Particularly in the case of a plate material made of magnetic material, if the first and second conveyance rollers are made of magnets, many effects such as the ability to perform the above-mentioned positioning G more accurately and quickly can be achieved.
