(57) [Summary] [Object] The present invention realizes a paper take-up shaft that can easily insert a paper without being affected by the shape of the end surface of the paper to be inserted. According to the present invention, in a paper take-up shaft 1a having a paper insertion groove 1b at a paper engaging portion, a notch 1c is provided at an end of the paper insertion groove 1b.
Description
【０００１】[0001]
本考案は紙挿入用の溝構造の一部に、切り欠き部を持つ小型プリンタの紙巻取 り軸構造に関する。 The present invention relates to a paper take-up shaft structure for a small printer, which has a notch in a part of a groove structure for inserting paper.
【０００２】[0002]
従来の紙巻取り軸構造は、紙咬合部に紙厚さより幅の広い紙挿入用溝が切って あり、印字紙を紙巻取り軸に挿入するときは、この紙挿入用溝に紙の端面を平行 に合わせながら挿入していた。 In the conventional paper take-up shaft structure, a paper insertion groove wider than the paper thickness is cut in the paper engagement part, and when inserting the printing paper into the paper take-up shaft, the end face of the paper is parallel to the paper insertion groove. I was inserting it according to.
【０００３】[0003]
しかし、前述の従来技術では、挿入する紙端面の形状によっては、紙挿入が容 易にできないという課題を有していた。 However, the above-mentioned conventional technique has a problem that the paper cannot be easily inserted depending on the shape of the end surface of the paper to be inserted.
【０００４】 本考案はこのような課題を解決するためになされたものであり、その目的とす るところは、挿入する紙端面の形状に影響されず、容易に紙挿入を行うことがで きる紙巻取り軸を提供するところにある。The present invention has been made to solve such a problem, and the purpose thereof is that the paper can be easily inserted without being affected by the shape of the end face of the paper to be inserted. It is in the area of providing a paper take-up shaft.
【０００５】[0005]
本考案は、上述の課題を解決し、紙咬合部に紙挿入用の溝構造を有する紙巻取 り軸において、紙挿入用の溝構造の一部に切り欠き部を設けたことを特徴とする 小型プリンタの紙巻取り軸構造。 The present invention solves the above-mentioned problems and is characterized in that in a paper take-up shaft having a groove structure for inserting a paper in a paper engaging portion, a cutout portion is provided in a part of the groove structure for inserting a paper. Paper winding shaft structure for small printers.
【０００６】[0006]
本考案の上記の構成によれば、紙挿入部の端面に切り欠き部を設けることによ り、紙挿入を行う場合、紙挿入部の切り欠き部構造によって、紙端面の形状に係 わらず、紙が紙挿入用の溝に誘導されて紙挿入が行われる。 According to the above configuration of the present invention, when the paper is inserted by providing the cutout portion on the end surface of the paper insertion portion, regardless of the shape of the paper end surface due to the cutout portion structure of the paper insertion portion. , The paper is guided by the paper insertion groove to insert the paper.
【０００７】[0007]
図１は、本考案の実施例における第１の説明図であって、紙巻取り軸１ａの表 面には紙挿入用の溝１ｂを有する。この紙挿入用の溝の形状は、直線で構成され ている。 図示しない印字紙を挿入する場合、この紙挿入用の溝１ｂの端部に設けた切り 欠き部１ｃ側から紙を挿入する。 この切り欠き部の形状は、切れ込み深さＡの寸法が、軸長さＢに対して１０〜 ２０％。切れ込み角度θが、１５〜３０゜の場合に、紙巻取に支障がなく、かつ 紙挿入が容易になることが確認されている。 図２は紙巻取り軸の正面図である。印字紙２は、切り欠き部１ｃの側から挿入 され、図のような状態となる。 FIG. 1 is a first explanatory view of an embodiment of the present invention, in which a paper insertion groove 1b is provided on the surface of a paper winding shaft 1a. The shape of this paper insertion groove is a straight line. When inserting a printing paper (not shown), the paper is inserted from the side of the notch 1c provided at the end of the paper insertion groove 1b. As for the shape of the cutout portion, the dimension of the cut depth A is 10 to 20% with respect to the axial length B. It has been confirmed that when the cutting angle θ is 15 to 30 °, there is no problem in winding the paper and the paper can be easily inserted. FIG. 2 is a front view of the paper winding shaft. The printing paper 2 is inserted from the side of the cutout portion 1c and is in a state as shown in the figure.
【０００８】 図３は、本考案の実施例における第２の説明図であって、切り欠き部１ｃの形 状がＲ付きでも、図１の形状のものと同様の効果があることが確認されている。 図４は、本考案の実施例における第３の説明図であって、紙巻取り軸の正面図 である。紙巻取り軸の中心に対して、切り欠き部１ｃをもつ図示しない紙挿入用 の溝が２カ所あり、１８０゜回転した状態で構成されている。このような構成の 紙巻取り軸においては、紙挿入を行う場合、紙挿入用の溝が１カ所の場合よりも 容易に見つけることができる。FIG. 3 is a second explanatory view of the embodiment of the present invention, and it is confirmed that even if the shape of the cutout portion 1c is R, the same effect as that of the shape of FIG. 1 is confirmed. ing. FIG. 4 is a third explanatory view of the embodiment of the present invention and is a front view of the paper winding shaft. There are two not-shown grooves for inserting the paper, which have notches 1c, with respect to the center of the paper winding shaft, and they are configured to be rotated by 180 °. In the paper take-up shaft having such a structure, when the paper is inserted, it can be found more easily than when there is only one groove for inserting the paper.
【０００９】[0009]
以上述べたように本考案によれば、切り欠き部を付加したことによって、挿入 する紙端面の形状に係わらず、紙挿入が容易となるという効果がある。 As described above, according to the present invention, the addition of the notch portion has the effect of facilitating the paper insertion regardless of the shape of the paper end surface to be inserted.
