ンタが広く普及している。(Prior Art) Currently, as a printer used for a data communication terminal device or a combination output device II'a, a platen is printed via an ink ribbon and printing paper by forming characters such as type or wire. So-called ink ribbon printers that print on printing paper by selectively hitting the paper are widely used.

雑となる。However, ink ribbon printers require an ink ribbon cassette to be installed and the ribbon to run, making the mechanism complicated.
In particular, in order to meet the demand for multicolor printing accompanying the recent diversification of printer usage, it becomes necessary to arrange multiple ribbons and print heads, making the mechanism even more complex.

に所定色で印字を行うプリンタである。A printing surface is formed by attaching a plurality of ink-impregnated porous bodies 5 impregnated with ink of each color to the outer peripheral surface of the print head 1, which has a wire 2 as a character forming element, through a printing paper 3, facing the print head 1. The ink-impregnated platen 4 is appropriately rotated to select an ink-impregnated porous body 5 of a predetermined color as a printing surface,
The printing paper 3 is removed by hitting the printing surface with the wire 2.
This is a printer that prints in a predetermined color.

As shown in the figure 1, a magnet 9 is attached to the groove 8' installed on the fq surface 8 of the platen base 7, and an iron plate 6 is attached to the bottom surface of the ink-impregnated porous body 5. If the body 5 is detachable from the platen base 7, the ink-impregnated porous body 5 can be easily replaced.

れる。Printing in the ink-impregnated platen type printer is achieved by the fact that when the surface of the ink-impregnated porous material is struck by a wire through the printing paper, the ink that oozes out from the surface of the ink-impregnated porous material is transferred to the printing paper. Immediately after printing is completed, ink is replenished at the printing point in preparation for the next printing.

Attempts have been made to incorporate MI UN powder such as silica and calcium carbonate, but satisfactory results have not been obtained.

で相対粘度３．５程反のしのを利用した。That is, as the nylon 6 resin, it is preferable to use a resin with a polymerization degree of 15° or higher, so it is preferable to use a resin with a polymerization degree of about 750, and as a nylon 661 HIli, it is preferable to use a resin with a molecular ff of 120,000 or higher. An anti-oxidant material with a relative viscosity of about 3.5 was used.

良好な結果を示した。The porous sintered bodies of the Examples and Comparative Examples were impregnated with oil-based inks based on fatty acids and fatty acid esters, and according to the results of examining the practicality of using them as ink-impregnated platens for U printers, each Example was compared with the Comparative Example. showed good results,
In particular, Examples 3 to 5, in which an appropriate amount of nylon resin with a lower melting point than nylon 6G resin was blended with the base nylon 6G resin, were extremely “C”.
It showed good results.

について記づ。Next, we will evaluate the practicality of the ink-impregnated platen by attaching it to a printer and printing approximately 1 million characters, the deformation m, the clarity of the print, and the dimensions when left in an atmosphere of R1190% at 35°C for 10 days. Describe the results obtained from the rate of change.

した。Comparative Examples 1 and 2, which are currently commonly used as nylon sintered bodies, are sintered bodies formed using only 1-6 or 66. With the increase, permanent deformation occurred, and the amount of deformation reached 165μ for nylon 6 and 120μ for nylon 66.
焼結体にはこの永久変形によって空孔の目詰りが生じる

くくなるので、前記した如き多きな永久変形が！［じた
ので印字の鮮明さはかなり低下した。If the pores of the sintered body become clogged due to this permanent deformation, it will be difficult for the ink to seep out and replenish smoothly during printing, resulting in a large amount of permanent deformation as described above! [The sharpness of the print was considerably reduced.
また吸湿による寸法の変化率はナイロン６で４．６％、

が示された。In addition, the dimensional change rate due to moisture absorption is 4.6% for nylon 6.
It was shown that the platen equipped with this sintered body had a high ζ1v of 3.5% for nylon 66 and lacked stability.

１つだしのである。Comparative Examples 3 and 4 are those in which the properties of the sintered bodies of nylon 6 or 66 are improved, and these are made by adding a low melting point nylon resin powder to the base nylon resin powder. Appropriate TTI blend improves sinterability and strengthens 8
It's only one.
この場合は変形量及び寸法変化率が多少改善されている

向上した。On the other hand, in the case of Examples 1 and 2 in which potassium titanate fibers were blended with nylon 6 or 66 resin, the deformation m was reduced to about 50μ due to the reinforcing effect of the potassium titanate fibers, resulting in good print clarity. The dimensional change rate is as in Example 1.
The dimensional stability was significantly improved by 2.8% in Example 2 and 2.1% in Example 2.

実施例５で１゜５％であり高い寸法安定性を示した。In this case, the surface hardness is extremely high at about Shore D75, the surface smoothness is maintained, and the amount of deformation is further reduced than in Examples 1 and 2 to about 30μ, so the sharpness of the printing is extremely good. is maintained and also=J
Legalization rate: 1.8% in Example 3, 2.6% in Example 4,
In Example 5, it was 1.5%, indicating high dimensional stability.

すぐれており極めて良好であった。As described above, each of the examples was inferior in practical performance as a sintered body for ink-impregnated pladen in a printer compared to the conventional comparative example. In particular, the polymer m of Examples 3 and 5
Nylon 66 resin is blended with nylon 612 or 12, which has a low melting point and low water absorption, and potassium titanate a! i
In the case of mixing miscellaneous materials, no permanent deformation occurred even when the number of prints m increased, and the prints were very clear, with sag, but excellent dimensional stability and excellent dimensional stability.

It is appropriate that the potassium titanate fibers to be blended have a length of 10 to 50μ in consideration of the reinforcing effect and not causing directional changes in dimension, and this blend m is If the amount increases, the porosity and strength will decrease, so the appropriate amount is 2 to 4011 M%, preferably 5 to 15% by weight.
