人手によることから、確実性が低く、正しく装着されな
い場合は紙づまりの原因となるなどの問題点があった。Since the conventional recording paper loading mechanism is configured as described above, when loading the recording paper, it is troublesome to pull out the leading edge of the recording paper and guide it onto the printing roller, and all of this is done manually. However, there were problems such as low reliability, and if not installed correctly, it could cause paper jams.
この発明は上記のような問題点を解消するためになされ
たもので、記録紙を受は台に置くだけで自動的に装着さ
れる機構を得ることを目的とする。This invention was made to solve the above-mentioned problems, and its object is to provide a mechanism in which recording paper can be automatically loaded simply by placing it on a tray.
この発明に係る記録紙装着機構は、記録紙先端をロール

く動作を、互いに逆転する一対のローラをロール状記録
紙に圧接することで可能にしたものである。The recording paper mounting mechanism according to the present invention is capable of peeling off the leading edge of the recording paper from the roll and guiding the leading edge to the printing roller by pressing a pair of rollers that rotate in opposite directions to the roll of recording paper. It is.
この発明における回転する一対のローラは、それぞれ記
録紙に対する摩擦係数が異なっており、摩擦係数の高い
ローラでロール状記録紙を回転させ、摩擦係数の低いロ
ーラで記録先端をローラからはく離させる。The pair of rotating rollers in this invention have different coefficients of friction with respect to the recording paper, and the roller with the higher coefficient of friction rotates the rolled recording paper, and the roller with the lower coefficient of friction peels off the leading edge of the recording paper from the roller.

In the figure, 1 is a roll of recording paper, 2 is a recording paper drive roller placed in contact with the recording paper, 3 is a separation roller that comes into contact with the recording paper 1 and the drive roller 2, 4 is an idler, and 5 is a 6 is a lower guide, 7 is a printing roller, 8 is a thermal recording head, and 9 is a recording paper tray. Note that the drive roller 2 and separation roller 3 have different friction coefficients with respect to the recording paper 1, and the drive roller 2 is set to have a larger coefficient of friction.

込まれ、記録紙の装着を完了する。Next, its operation will be explained. First, the roll of recording paper 1 is placed so that its winding end is between the upper separation roller 3 and the idler 4, and the roll of recording paper 1 is rotated by the recording paper drive roller 2 in the direction of the arrow. At this time, the separating roller 3 is in pressure contact with the recording paper drive roller 2, so it is rotating in the opposite direction, but since the coefficient of friction against the recording paper is lower than that of the recording paper drive roller 2, it may slip between it and the recording paper. 6 Next, due to the rotation of this roll of recording paper 1, the end of the recording paper eventually gets caught between the separation roller 3 and the friction coefficient between the separation roller 3 and the recording paper 1. Since the recording paper is higher than that, the reverse rotation of the separation roller 3 separates the end of the recording paper from the roll and sends it toward the lower guide 5. Further rotation of the roll of recording paper 1 causes the separated end of the recording paper to be moved to the lower part. The recording paper advances between the guide 5 and the upper guide 6 and reaches the printing roller 7, and due to the rotation of this printing roller rough, it is caught between the thermal recording head 8 and the mounting of the recording paper is completed.

れた効果を奏する。As described above, according to the present invention, recording paper can be loaded automatically by simply pressing a pair of rollers that rotate in reverse directions against the roll of recording paper, so it is not troublesome, and it is possible to load the recording paper reliably while at the same time It has excellent effects such as no fear of clogging.
