ＯＨＰと略称される）を用い、透明なフィルム・シート
（ＯＨＰ用ＴＰフィルムと称せられる）に描かれた図
面等を写し出すことが行われている。(abbreviated as OHP) is used to copy drawings etc. drawn on transparent film sheets (referred to as TP film for OHP).

しかして、このフィルム・シートに図面等を描くには、
手書き （手書法という）により行うかあるいは感熱複
写法により行っていたが、近年の複写技術の発達に伴い
普通紙複写（ｒｐｃ）方式によりこれを行うことが可能
になるに至った。However, in order to draw drawings etc. on this film sheet,
This was done by handwriting (referred to as handwriting) or by thermal copying, but with the recent development of copying technology, it has become possible to do this by using plain paper copying (RPC).

ところが、この方式を採る場合において、フィルム・シ

ートを保存するに際し嵩高となったり取扱いが不便であ
る等の欠点がある。However, when this method is adopted, the film/sheet must be able to withstand the heat generated when the toner adheres to a fixed position, and have good conveyance properties. It has to be 150μ thick, which increases the cost, and also has drawbacks such as being bulky and inconvenient to store the film/sheet.

本考案は、ＯＨＰ用として用いることができ従来の普通
紙複写用フィルム・シートが有する欠点を解消するため
に案出されたもので、実施例の図面に示すように透明フ
ィルムシート１と基板となるべき紙シート２とを接着剤
３により接合せしめたものである。The present invention can be used for OHP purposes and was devised to eliminate the drawbacks of conventional plain paper copying films and sheets.As shown in the drawings of the embodiment, a transparent film sheet 1 and a substrate are The desired paper sheet 2 is bonded with an adhesive 3.

透明フィルムシート１は従来と同様ポリエステル製とし
たり、セロハン製とすることができ、紙シート２は一般
の上質紙とすることができる。The transparent film sheet 1 can be made of polyester or cellophane as in the past, and the paper sheet 2 can be made of general high-quality paper.

透明フィルムシート１と紙シート２とは両者の剥離が容
易で、しかも両者を剥離したときには透明フィルムシー
ト１に接着剤が残存しないようにすることが望ましい。It is desirable that the transparent film sheet 1 and the paper sheet 2 can be easily peeled off, and that no adhesive remains on the transparent film sheet 1 when they are peeled off.

その理由は複写後においては透明フィルムシートがその
用をなすだけであって紙シート２は不要であるからであ
る。The reason for this is that after copying, the transparent film sheet serves only that purpose, and the paper sheet 2 is not necessary.

それには、接着剤としてポリ酢酸ビニル系、ポリアミド
系、ポリアクリル酸エステル系もしくはポリウレタン系
のように透明フィルムシート１に対して比較的接着性が
良くないものを用いるとよく、また、透明フィルムシー
ト１の接着面（裏面）に離型剤としてシリコン樹脂を塗
布し、いわゆる離型処理を施してもよい。For this purpose, it is best to use an adhesive that has relatively poor adhesion to the transparent film sheet 1, such as polyvinyl acetate, polyamide, polyacrylic acid ester, or polyurethane adhesive. A so-called mold release treatment may be performed by applying a silicone resin as a mold release agent to the adhesion surface (back surface) of 1.

また、必要に応じ紙シート２に切目を施してもよい。Further, the paper sheet 2 may be cut if necessary.

本案によれば、透明フィルムシート１に基板となる紙シ
ート２が重着（いわゆるラミネート）されているから、
透明フィルムシート１を可及的に薄くすることができ、
これをＯＨＰ用として用いる場合においては透明フィル

の面で何ら問題はなく、安価とすることができ、また、
該フィルルムシートを第２原図用として用いた場合にお
いては透明性が良く、複写スピードも早くしかもこれを
安価とすることができる。According to the present invention, since the paper sheet 2 serving as a substrate is superimposed on the transparent film sheet 1 (so-called lamination),
The transparent film sheet 1 can be made as thin as possible,
When using this for OHP, even if the transparent film sheet 1 is thin, there is no problem in terms of heat resistance and transportability, it can be made inexpensive, and
When the film sheet is used as a second original, it has good transparency, fast copying speed, and can be made at low cost.
