Description

本発明は、インクリボン、紙、フィルム等のシート状物のリボンを巻き取るリボン巻き取りリールに関し、特に紙管等の軸芯を用いることなく周面にリボンを直接巻き取るリボン巻き取りリールに関する。   The present invention relates to a ribbon take-up reel that takes up a ribbon of a sheet-like material such as an ink ribbon, paper, or film, and more particularly, to a ribbon take-up reel that directly winds a ribbon around a peripheral surface without using an axial core such as a paper tube. .

紙管等の軸芯を用いることなくリボン巻き取りリールの周面にリボンを直接巻き取る場合には、巻き取ったリボンをリボン巻き取りリールの周面から抜き取るための機構が必要となる。   When the ribbon is directly wound around the peripheral surface of the ribbon take-up reel without using an axis such as a paper tube, a mechanism for extracting the wound ribbon from the peripheral surface of the ribbon take-up reel is required.

巻き取ったリボンをリボン巻き取りリールの周面から抜き取るための機構としては、一方の端部間が弾力性を有する第１の接続部材で接続された複数のリール胴体部と、他方の端部間を接続する第２の接続部材とでリボン巻き取りリールを構成し、巻き取ったリボンを抜き取る際には、第２の接続部材を取り外し、第１の接続部材を屈曲又は湾曲させ、複数のリール胴体部における他方の端部を接触させることで、リール胴体部の外径を小さくし、巻き取られたリボンを抜き取るようにした機構が提案されている（例えば、特許文献１参照）。   As a mechanism for pulling out the ribbon taken up from the peripheral surface of the ribbon take-up reel, a plurality of reel body portions in which one end portion is connected by a first connecting member having elasticity, and the other end portion A ribbon take-up reel is configured with a second connecting member that connects between the two, and when the taken-up ribbon is pulled out, the second connecting member is removed, the first connecting member is bent or curved, There has been proposed a mechanism in which the other end of the reel body is brought into contact with the reel body so that the outer diameter of the reel body is reduced and the wound ribbon is pulled out (see, for example, Patent Document 1).

しかしながら、従来技術では、巻き取られたリボンを抜き取る際に、リール胴体部の外径が幅方向で異なり、特に第１の接続部材で接続された付近では、外径がほとんど小さくならないため、巻き取られたリボンを抜き取りにくいと共に、リール胴体部の外径を小さくするために第２の接続部材を取り外す必要があり、取り外した第２の接続部材の取り扱いを意識しながら巻き取られたリボンの抜き取り作業を行う必要があって煩雑であるという問題点があった。   However, in the prior art, when the wound ribbon is pulled out, the outer diameter of the reel body is different in the width direction, and the outer diameter is hardly reduced particularly in the vicinity of being connected by the first connecting member. It is difficult to remove the taken ribbon, and it is necessary to remove the second connecting member in order to reduce the outer diameter of the reel body, and the ribbon wound up while being conscious of handling the removed second connecting member. There is a problem that it is complicated because it is necessary to perform the sampling operation.

In the ribbon undrawn state, the rotation plate 2 and the ribbon take-up shaft 1 are configured so that the fixing in the rotation direction is released. There is provided a rotation detecting means for detecting, and by comparing the rotation speed of the ribbon take-up shaft 1 with the rotation speed detected by the rotation detecting means, the ribbon winding state and the ribbon drawing state can be recognized. Play.
