Abstract

PURPOSE:To enable a sheet to be reused, by erasing a character or image printed with a soluble ink on the sheet, through wiping off the character or image by use of an erasing liquid. CONSTITUTION:The surface of a sheet 101 need not be smooth, but the sheet is preferably impermeable to an ink. For example, a plastic sheet with a surface slightly roughened or treated to appear white is preferable for use as the sheet 101. A soluble ink 102 applied by ink jet recording or the like is collected by wiping with a wiping member 103 impregnated with a correcting liquid, to become a dissolved ink 104. The wiping member 103 is preferably formed of an elastic foamed material so that the member 103 does not come out of contact with the sheet 101 during wiping and can be impregnated with the correcting liquid. An example of such a material is a foamed urethane rubber. Water with or without an alcohol dissolved therein, for example, is effective for use as the erasing liquid for an ink used for ink jet recording.

Description

【発明の詳細な説明】 産業上の利用分野 本発明はそれを利用してシート上に可溶性のインクで描
いた文字や画像を消去し、シートの再利用を可能にする
印刷文字消去方法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a printed character erasing method that utilizes the method to erase characters and images drawn on a sheet with soluble ink, thereby making it possible to reuse the sheet.

従来の技術 電子ファイル化されたデータ等をプリントにするほどの
こともなく単にモニタしたいという要求がある。この目
的のためには普通ＣＲＴや液晶等のデイスプレィを用い
る。BACKGROUND OF THE INVENTION There is a demand for simply monitoring data converted into electronic files without printing them. A display such as a CRT or liquid crystal is usually used for this purpose.

発明が解決しようとする問題点 しかしながら、上記のようなあるいは現在筒便に使える
デイスプレィは資料の一部しか画面に映出できず、不便

た、消去も繰り返し完全に出来るものではなかった。Problems to be Solved by the Invention However, the above-mentioned or currently available displays are inconvenient because only a portion of the material can be displayed on the screen. It is also difficult to carry around. In order to meet this demand, research has been carried out on rewritable sheets using photochromic or the like, but the printing quality is far from being comparable to that of the printed materials currently in widespread use. In addition, it was not possible to completely erase the data repeatedly.

シート上に可溶性インクで描いた文字や画像を消去液を
用いて拭き取るようにしている。Means for Solving the Problems In order to solve the above problems, the printed character erasing method of the present invention uses an erasing liquid to wipe off characters and images drawn on a sheet with soluble ink.

なるように処理をしたプラスチックシートが好ましい。EXAMPLE Hereinafter, the printed character erasing method of the present invention will be explained with reference to the drawings. The figure shows the character erasing method of the present invention. In the figure, 101 is a sheet. The surface of the sheet does not need to be smooth, but it should be one that does not allow ink to soak into it. For example, a plastic sheet whose surface is slightly roughened or treated to make it white is preferable.

１０２はインクジェット等を用いて印刷した可熱溶性の
インクである。１０３は消去液を染み込ませた拭き取り
部材である。１０４は拭き取り部材１０３によって拭き
集められた溶解したインクである。102 is a thermosoluble ink printed using an inkjet or the like. 103 is a wiping member impregnated with erasing liquid. 104 is the dissolved ink wiped and collected by the wiping member 103.

拭き取り部材１０３は拭き取り中にシート１０１の表面
から離れないように、また消去液を含むことが出来るよ
うに弾力があって、発泡性の物が良好である。そのよう
なものには例えば、発泡ウレタンゴムがある。消去液に

いはこれにアルコールを溶かせたものが有効である。The wiping member 103 is preferably elastic and foamable so that it does not separate from the surface of the sheet 101 during wiping and can contain the erasing liquid. An example of such a material is foamed urethane rubber. For example, for inkjet ink, water or a solution of alcohol dissolved therein is effective as the erasing liquid.

発明の効果 本発明の印刷文字消去方法はシート上に可溶性インクで
描いた文字や画像を消去液を用いて拭き取り、消去する
ようにしているため、文字の品質は通常の印刷と変わら
ないが、消去出来るためにシートを再使用することがで
きる。Effects of the Invention Since the printed character erasing method of the present invention uses an erasing liquid to wipe and erase characters and images drawn with soluble ink on a sheet, the quality of the characters is the same as that of normal printing, but Since it can be erased, the sheet can be reused.
