Abstract
Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は端末機器等の給紙機構に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a paper feeding mechanism for terminal equipment and the like.
従来、この種の給紙機構は第２図に示すように最終用紙
７の重送を防止するために用紙６，７を給紙ローラ４に
押し付けるためのプレート２の一部にコルクや布等の摩
擦板１０を取り付けていた。Conventionally, as shown in FIG. 2, this type of paper feeding mechanism has a part of the plate 2 that presses the sheets 6 and 7 against the paper feed roller 4 in order to prevent double feeding of the final paper 7, such as cork or cloth. A friction plate 10 was attached.
上述した従来の摩擦板は、用紙を給紙ローラに押し付け
るためのプレートとは全く別の材質を使用しているため
部品点数が多くまた！ｇ擦板の貼付等の作業が必要であ
り原価が高くなるという欠点がある。The conventional friction plate mentioned above uses a completely different material from the plate for pressing the paper against the paper feed roller, so it has many parts! G. It requires work such as pasting the rubbing board, which has the drawback of increasing the cost.
本発明の給紙機構は、用紙を給紙ローラに押し付けるた
めのプレートの一部をサンドブラスト処理により荒らし
て粗面としている。In the paper feed mechanism of the present invention, a part of the plate for pressing the paper against the paper feed roller is roughened by sandblasting to give a rough surface.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例の縦断面図である。FIG. 1 is a longitudinal sectional view of an embodiment of the present invention.
プレート２はベー、スｌにより保持されスプリング３に
よって給紙ローラ４に押し付けられている。The plate 2 is held by a base and a slider and is pressed against a paper feed roller 4 by a spring 3.
プレート２はプレート表面に荒れた部分５を有している
。The plate 2 has a rough portion 5 on the plate surface.
次に動作を説明する。最後から２番目の用紙６が給紙さ
れる時、最終用紙７は給紙ローラ４により搬送力８を受
ける。この搬送力８は最終用紙７とプレート表面の荒れ
た部分５との摩擦力９により打ち消され、最終用紙７は
最後から２番目の用紙６と同時に搬送されることはない
。Next, the operation will be explained. When the second to last sheet 6 is fed, the last sheet 7 is subjected to a conveying force 8 by the sheet feeding roller 4. This conveying force 8 is canceled by the frictional force 9 between the final sheet 7 and the rough portion 5 of the plate surface, so that the final sheet 7 is not conveyed at the same time as the second-to-last sheet 6.
以上説明したように本発明は用紙と同等またはそれ以上
の摩擦係数となるようにプレートの表面を荒らすことに
より部品点数を少なくし、また最終用紙の重送をなくす
効果がある。As explained above, the present invention has the effect of reducing the number of parts and eliminating double feeding of the final sheet by roughening the surface of the plate so that the coefficient of friction is equal to or higher than that of the paper.
