In the manufacturing process of printed circuit boards, etc., when exposing and printing an original image onto a workpiece, it is necessary to bring the original image film into close contact with the printed circuit board workpiece in order to perform accurate exposure. The frame provides vacuum sealing.

ようとするものである。 As shown in FIG. 3, this baking frame includes an upper frame 10 and a lower frame 11 made of deformable acrylic plates.
A gasket 12 fixed to the periphery of the lower frame 11
The original image (negative or positive) film 13 and workpiece 14 are placed in a stacked manner inside the gasket 12 of the lower frame 11, and then the upper frame 10 is brought into close contact with the gasket 12, and the vacuum port 15 is opened as shown in the figure. The original image film 13 and the workpiece 14 are pressed against each other by deforming (deflecting) the upper frame 10 and the lower frame 11 to bring them into close contact with each other.
しかしながら、上記従来の焼枠には以下のよう
な解決すべき課題を有していた。
However, the above-mentioned conventional baking frame had the following problems to be solved.
まず第１に、従来のガスケツトの高さは一定で
あり、ワークの厚さの種類によつては密着性に問
題が生じていた。すなわち、上枠と下枠のたわみ
によりワークと密着を行なうため、薄いワークで
あるとガスケツトの近くではワークの周縁部との
密着が悪くなつていた。また、ガスケツトの高さ
よりも厚いワークは、当然上下の枠体の密着がで
きないために利用することはできなく、このため
ワークの厚みに対応させた複数の焼枠を作成して
用意しなければならなかつた。 First of all, the height of conventional gaskets is constant, which causes problems in adhesion depending on the thickness of the workpiece. That is, since the upper frame and the lower frame are in close contact with the workpiece due to their bending, if the workpiece is thin, the close contact with the peripheral edge of the workpiece is poor near the gasket. Also, if the workpiece is thicker than the gasket height, it cannot be used because the upper and lower frames cannot fit tightly together, so multiple baking frames must be prepared to accommodate the thickness of the workpiece. It didn't happen.
第２に、真空密着の繰り返し作業により、ガス
ケツトには、上枠と下枠に加わる大気圧による枠

ルドが果たせなくなり、ガスケツトの付け替えま
たは焼枠の作り直しを頻繁に行なわなければなら
なかつた。 Second, due to the repeated vacuum sealing operation, atmospheric pressure is directly and repeatedly applied to the gasket from the lateral direction, as well as pressure between the frames due to atmospheric pressure applied to the upper and lower frames. Conventional gaskets deteriorate quickly due to the action of these forces, making it impossible to provide vacuum shielding, and the gaskets must be replaced or the baking frame rebuilt frequently.
本考案は、このような課題に鑑みて創案された
ものであり、その目的とするところは、ワークの

提供しようとするものである。 The present invention was devised in view of these issues, and its purpose is to make it possible to adjust the height dimension according to the thickness of the workpiece, and to reduce the force that is repeatedly applied. It is an object of the present invention to provide a gasket for a baking frame that has improved durability against action.

In order to achieve the above object, the printing frame gasket according to the present invention is a printing frame in which a document image and a work are placed between upper and lower frames, and the frames are brought into close contact by reducing the pressure for exposure and printing. A gasket for a baking frame is constructed on the periphery between the frames and serves as a shield from the outside air, and the gasket on one side is formed into a U-shaped cross section and a spacer is inserted inside the frame on one side. , a main contact convex portion on the other side of the frame body, which is in close contact with the gasket on the one side and serves as a shield from outside air during depressurization and mainly receives the pressure between the frame bodies;
The other side gasket is fixedly formed with a support protrusion formed lower than the height of the main contact protrusion and secondarily comes into close contact with the one gasket during depressurization to serve as a shield from the outside air. It is what it is.
焼枠などに構成されるガスケツトは、一般的に

ワークに対応させることができる。 Therefore, in the present invention, the height of the gasket is changed by changing the thickness of the spacer inserted into the gasket on one side, which is formed in the frame on one side and has a U-shaped cross section. As a result, the interval between the frames can be adjusted in accordance with the thickness of works of different thicknesses, and one baking frame can be used for a plurality of types of works.

の耐久性を高めることができる。 In addition, the gasket on the other side, which is composed of the main contact convex part and the support convex part, which are constructed on the frame body on the other side, has a main contact convex part that first comes into close contact with the gasket on the one side
During decompression, the main contact convex part receives the pressure between the frame bodies, whereas the main contact convex part of the support convex part receives the pressure between the frame bodies.
Once compressed to a certain extent, they come into close contact with each other, and each convex part serves as a shield from the outside air. This allows the external force due to atmospheric pressure to be applied directly from the side,
The durability of the gasket can be increased because the gaskets are distributed and received at each convex portion.

The upper frame 2 with the spacer 5 selected corresponding to the thickness of the upper gasket 4 inserted into the upper gasket 4 is brought into close contact with the lower frame 3 by aligning each gasket with the spacer 5, and then the spacer 5 is inserted into the upper gasket 4. Reduce the pressure between the frames. At this time, in the lower gasket 6, only the main contact convex portion 6a is initially in close contact with the upper gasket 4 of the upper frame 2, and the pressure is reduced while shielding from the outside air, and the upper and lower parts due to atmospheric pressure accompanying this pressure reduction occur. As the frame body bends, it is pressed and compressed between the frame bodies. When the main contact convex portion 6a is compressed to some extent, the support convex portions 6b and 6c on both sides
is in close contact with the upper gasket 4, and is pressed and compressed between the frames until the decompression is completed, while still serving as a shield from the outside air. When the pressure reduction is completed, the lower gasket 6 is in a state in which the pressure from the upper and lower frames is mainly received by the main contact convex portion 6a, and the atmospheric pressure that is directly applied in the lateral direction is distributed and received by the three convex portions.
