Description

本発明の媒体送り装置は、印刷媒体がロール状に巻かれたロール体から繰り出された、印刷媒体を送る送り部と、送られる印刷媒体の幅方向の端部に接触可能な位置に設けられ、送られる印刷媒体をガイドするガイド部と、印刷媒体の送り経路においてガイド部とロール体との間に設けられ、印刷媒体に作用するテンションの変動に追従して移動するテンションレバーと、ロール体を、印刷媒体を繰り出す繰出し方向に回転可能、且つ、ロール体の軸方向に移動可能、に支持するロール体支持部と、を備えたことを特徴とする。 The medium feeding device of the present invention is provided at a position where the printing medium is fed from a roll body wound in a roll shape and can be contacted with a feeding section for feeding the printing medium and an end in the width direction of the printing medium to be fed. a guide portion for guide the print medium to be sent, is provided between the guide portion and the roll body in the feed path of the print medium, a tension lever that moves following the fluctuation of the tension acting on the printing medium, a roll And a roll body support portion that supports the body so as to be rotatable in a feeding direction for feeding out the print medium and movable in the axial direction of the roll body.

この場合、ロール体支持部は、ロール体のコア部に挿入され、ロール体が装着されるロール体装着部と、ロール体装着部の軸心に挿入され、ロール体装着部を、回転可能、且つ、軸方向に移動可能に支持するロール軸と、を有することが好ましい。 In this case, the roll body support portion is inserted into the core portion of the roll body, and is inserted into the roll body mounting portion on which the roll body is mounted, and the roll body mounting portion, and the roll body mounting portion can be rotated. And it is preferable to have a roll shaft supported so as to be movable in the axial direction.

この場合、ロール体装着部を回転させて、ロール体を繰出し方向に回転させるロール体駆動部、をさらに備えたことが好ましい。 In this case, by rotating the roll member mounting portion, the roll body driving portion you want to rotate. The roll body in the extending direction, it is preferable to further comprising a.

この場合、送り部が、ロール体に向けて、印刷媒体を逆送りするとき、ロール体駆動部は、ロール体装着部を回転させて、装着されたロール体を、印刷媒体が巻き取られる巻取り方向に回転させることが好ましい。 In this case, feed unit, toward the roll body, when the reverse feed the print medium, the roll body driving unit rotates the roll body mounting portion, the loaded roll body, is that is taken wound print medium Rukoto rotated in the winding direction is preferred.

この場合、ロール体駆動部は、ロール体装着部に対する動力の出力端となる出力ギア、を有し、ロール体装着部は、出力ギアに係合する入力係合部、を有し、入力係合部は、出力ギアに対して軸方向に相対的に移動することが好ましい。 In this case, the roll body driving unit includes an output gear, as an output terminal of the power with respect to the roll body mounting portion, the roll body mounting portion, have a input engaging portion, which engages with the output gear, an input engagement The joint portion preferably moves relative to the output gear in the axial direction .

この場合、ロール体装着部は、ロール軸に対するロール体装着部の回転およびロール体装着部の軸方向への移動を案内する軸受、を有することが好ましい。 In this case, the roll body mounting part preferably has a bearing for guiding the rotation of the roll body mounting part relative to the roll shaft and the movement of the roll body mounting part in the axial direction.

この場合、ロール体装着部に装着されたロール体の軸方向における端面に接触するフランジ、をさらに備えることが好ましい。 In this case, it is preferable that Ru further comprising a flange, which contacts the end surface in the axial direction of the roll body mounted on the roll body mounting portion.

本発明の印刷装置は、印刷媒体がロール状に巻かれたロール体から繰り出された印刷媒体を送る送り部と、送られる印刷媒体の幅方向の端部に接触可能な位置に設けられ、送られる印刷媒体をガイドするガイド部と、印刷媒体の送り経路においてガイド部とロール体との間に設けられ、印刷媒体に作用するテンションの変動に追従して移動するテンションレバーと、送り経路においてガイド部に対してテンションレバーと反対側に設けられ、印刷媒体に印刷を行う印刷部と、ロール体を、印刷媒体を繰り出す繰り出し方向に回転可能、且つ、ロール体の軸方向に移動可能、に支持するロール体支持部と、を備えたことを特徴とする。 The printing apparatus of the present invention is provided at a position where it can come into contact with a feed section that feeds a print medium fed from a roll body in which the print medium is wound in a roll shape, and an end in the width direction of the print medium that is fed. A guide portion that guides the print medium to be printed, a tension lever that is provided between the guide portion and the roll body in the feed path of the print medium, and moves in accordance with a change in tension acting on the print medium, and a guide in the feed path Is provided on the opposite side of the tension lever to the printing unit , and supports the printing unit for printing on the printing medium and the roll body so that it can be rotated in the feeding direction for feeding out the printing medium and can be moved in the axial direction of the roll body. And a roll body support section .
