【考案の詳細な説明】
本考案は、プリンターで印字された巻紙を保管の便宜の
ために巻取る必要がある装置に関し、特に自動巻取り機
構の構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that needs to wind up a paper roll printed by a printer for convenience of storage, and particularly relates to the structure of an automatic winding mechanism.
従来この種の巻取機構は巻取軸に溝を設け、それに巻紙
の繰出し端を手で挿入し更に数回巻紙を巻取軸に巻き付
けている。Conventionally, in this type of winding mechanism, a groove is provided in the winding shaft, the unwinding end of the paper is manually inserted into the groove, and the paper is further wound around the winding shaft several times.
この作業にかいて巻取軸と巻紙の平行が極端にずれてい
ると、巻取り不良が発生することがあるので慎重に行う
必要があった。This work had to be done carefully because if the winding shaft and paper are not parallel to each other extremely, poor winding may occur.
また巻取軸の溝が狭いため紙を挿入しにくいとか、巻紙
を確実に一体にするためにある程度の熟練を必要とした
。In addition, the groove in the winding shaft was narrow, making it difficult to insert the paper, and a certain level of skill was required to securely hold the paper in one piece.
これを除去するために中空円筒を有するケースの中の軸
芯に羽根をつけてこれを回転することによって巻取る自
動巻取り機構もあるが、この場合巻取りのために円筒ケ

円筒ケース内にあるため、巻取軸から巻紙をとり出す操
作の前段階としてケースを軸と分離しなければならない
ため前記従来の巻取り機構よりも操作性において欠点が
あった。In order to remove this, there is an automatic winding mechanism that attaches a blade to the shaft core inside a case with a hollow cylinder and winds it by rotating it, but in this case, a cylindrical case is required for winding. When taking out the rolled paper, since the paper is inside the cylindrical case, the case must be separated from the shaft before taking out the paper from the winding shaft, making it easier to operate than the conventional winding mechanism. There were some drawbacks.
また最大外径を規制した巻取り機構では少しだけ巻き取
ったときと巻紙−春分巻き取ったときと巻取り外径が全
く同一であり、−春分全部巻きとらないで少しだけ巻い
たものを取りはずした場合外径が大きいため巻き付いた
ものが緩みを生じ保管性が悪く、硬く巻き直ししたりす
る作業が必要であった。In addition, with a winding mechanism that regulates the maximum outer diameter, the outer diameter of the winding paper is exactly the same when only a small amount is wound and when the spring roll is wound, and the winding paper is not completely wound but only a small amount is removed. When the outer diameter is large, the wrapped material becomes loose, making it difficult to store, and it is necessary to re-wrap it tightly.
本考案は従来の巻取り機構の欠点を解決することを目的
として従来軸支していた巻取軸を上下方向（重力作用方

ローラ軸側と巻取軸側とを離脱可能にすることにより回
転伝達用摩擦車と一体となった巻取軸を容易に着脱可能
にした自動巻取り機構を提供することにある。The purpose of this invention is to solve the drawbacks of conventional winding mechanisms by making it possible to move the winding shaft, which was conventionally supported, up and down (in the direction of gravity action), so that the winding shaft is moved by gravity to the protrusion on the guide plate. Since the paper is in close contact with the winding shaft, when the unwinding end of the paper roll is sent out there, it is drawn between the protrusion of the guide plate and the winding shaft, and the winding paper is wound around the winding shaft. By removing the cylindrical case required for winding and making it possible to separate the pinch roller shaft side and the winding shaft side of the friction transmission mechanism, the winding shaft integrated with the friction wheel for rotation transmission can be easily attached and detached. The purpose of the present invention is to provide an automatic winding mechanism that makes it possible.
本考案は巻取軸に伝達する中間回転伝達用摩擦車がピン
チローラ側回転伝達用摩擦車と一体構造で、ピンチロー
ラ側軸を中心として回転離脱可能にしたため巻取軸の着
脱が極めて簡単に行うことができる。In this invention, the friction wheel for transmitting intermediate rotation to the winding shaft is integrated with the friction wheel for transmitting rotation on the pinch roller side, and can be rotated and removed around the shaft on the pinch roller side, making it extremely easy to attach and detach the winding shaft. It can be carried out.
また、ゴム等のローラから成る巻取軸が重力でベース上

き巻紙の端は巻取軸ローラの摩擦力によりすみやかに引
き込まれその先にある弾性体の案内板に案内されて巻紙
の先端をするめられることにより巻取軸ローラに強固に
巻き付き緩みのない確実な巻取りが可能になった。In addition, the winding shaft, which is made of rollers made of rubber, is placed on the base by gravity and is able to rotate in close contact with the base. The paper is quickly drawn in by the frictional force of the take-up shaft roller, guided by an elastic guide plate at the end of the paper, and the leading edge of the paper is wrapped around the take-up shaft roller, ensuring reliable winding without loosening. Became.
またベースと巻取軸ローラの接触部はベース側に複数個
の突起部を備えることにより巻紙が滑って巻き込捷れて
ゆく過程での摩擦面を最小限におさえることができ印字
面のよごれを少なくするよう考慮しである。In addition, the contact area between the base and the take-up shaft roller is equipped with multiple protrusions on the base side, which minimizes the friction surface during the process of the paper slipping, winding up, and twisting, thereby preventing dirt on the printed surface. This is done in consideration of reducing the amount of damage.
本考案は巻取軸のローラを摩擦力の大きい材質で形威し
該巻取軸を重力を利用してベース上に密着させて回転さ
せるため送られてきた巻紙の端を引き込みやすくなって
いる。In this invention, the roller of the winding shaft is made of a material with a high frictional force, and the winding shaft is brought into close contact with the base and rotated using gravity, making it easier to pull in the end of the paper being fed. .
またベースと巻取軸ローラとの接触面においてローラと
巻紙とベース間の摩擦抵抗が異なるため巻取軸ローラの
巻き付きが強固となり緩みのない確実な巻取りができる
。Furthermore, since the frictional resistance between the roller, the wrapping paper, and the base is different at the contact surface between the base and the winding shaft roller, the winding of the winding shaft roller becomes strong, and reliable winding without loosening is possible.
また巻取り量の増加に伴ない巻取軸の軸心が上方へ移動
できるようにしである。Further, the axis of the winding shaft can be moved upward as the amount of winding increases.
