Abstract

PURPOSE:To obtain a sufficient hiding property through repeatedly coating a misprinted character with a white correction layer having a coating thickness of not more than 10mum, by providing a thermal transfer type typewriter with a machanism for repeatedly applying a thermally transferrable white correction layer to the same part in a one-time operation. CONSTITUTION:The thermal transfer type typewriter is provided with the mechanism for repeatedly applying the thermally transferrable white correction layer to the same part in a one-time operation. With this typewriter, a misprinted character can be corrected with a sufficient hiding property and without any problem on transfer property. Namely, when the white correction layer having a coating thickness of not more than 10mum is applied to a misprinted character repeatedly two or more times, the total thickness becomes not less than 20mum, and a sufficient hiding property can be obtained. In addition, since the transfer is conducted with a thickness of 10mum each time, incomplete transfer does not occur. Further, since the correction of misprinted character is not performed frequently, the repeated application of the correction layer does not cause the problem of considerable lowering in efficiency.

しい。DETAILED DESCRIPTION OF THE INVENTION So-called thermal transfer typewriters and printers have a low 197B sound, low power consumption, and have excellent printing quality such as long shelf life and clarity. Because it has a prefecture, it has experienced remarkable development in recent years.

しかし、感熱転写方式、特にタイプライタ−むこおむする問題、へζよ４県字のす修正である
。通常のインパクトタイプのタイプライタ−においては、誤字の上に酸化チタンなどの白色顔料を含む白色修正層を重ね打ちする事により、誤字を隠蔽する方法が一般に行われている。However, the thermal transfer method, especially the typewriter, has problems that require correction. In ordinary impact type typewriters, a method of concealing typographical errors is generally carried out by overprinting a white correction layer containing a white pigment such as titanium oxide on the typographical errors.

かかる手法を感熱転写型タイプライタ −に適用せんとすると、次の問題点がある。This method was applied to a thermal transfer typewriter. −, the following problems arise. be.

白色修正層の厚さは少く共２θμ以上を要する。That is, typographical error (black) -f? In order to completely conceal the skin, even if one uses 1ef titanium, which is said to have the highest concealing power among the white face pigments, the thickness of the white correction layer must be at least 2θμ or more.

とがるが、感熱転写は、基材紙又は基材フィルムの背面より印字ヘッドによって与えられる限られた熱量によって感熱転写層が溶融し、紙等に転写するものであり、白色修正層を打字する場合も同様であるから感熱転写Ｎ（白色修正層の場合も同じ）の厚さが、厚過ぎると、熱量が不足し、転写が不完全となる。許容される厚さの限度は、印字条件により若干具るが、最高／θμ 位までである。Although it is sharp, thermal transfer is from the back of the material film to the print head. Due to the limited amount of heat given by The heat-sensitive transfer layer melts and transfers to paper, etc. , and when printing the white correction layer.

全にカバーする事は出来ない。この為、未だ修正機構を備えた感熱転写型タイプライタ−は市販されていないのが現状である。これに対し、本発明の方法によれば、転写性も問題なく、隠蔽性も充分な修正を行う事が出来るすなわち、塗布厚／θμ以下の白色修正層を、誤字の上に少く共２度以上、重ね打ちを行うと、総厚、２０μ以上と又７度の転写は
／θμずつであるので転写不良を起こす事もない。Therefore, is there enough concealment? If the thickness of the white correction layer is made to be more than 2θμ in order to obtain the correct color, it will result in poor transfer, and if it is less than 70μ, the transfer will be better. . For this reason, there is currently no thermal transfer type writer equipped with a correction mechanism on the market. On the other hand, according to the method of the present invention, there is no problem in transferability and sufficient concealment can be corrected. In other words, a white correction layer with a coating thickness of less than θμ is applied at least twice over the typographical errors. As described above, when overprinting is performed, the total thickness is 20μ or more, and the 7 degrees of transfer is /θμ, so no transfer defects occur.

又誤字の修正は頻度が少いので、複数回打字する事による能率の低下も問題にはならない。Also, since typographical errors are rarely corrected, multiple Reduced efficiency due to double typing is also a problem. It won't be.
