Zusammenfassung: | To make it possible to reduce a space for a rotation shaft (second rotation shaft) when viewed in the axial direction.SOLUTION: A drive mechanism comprises: first transmission means that is fixed to a first rotation shaft of a first driving roller rotated by a driving force from a driving source and rotates integrally with the first rotation shaft; second transmission means that is provided capable of idling with respect to a second rotation shaft of a second driving roller facing the first driving roller and to which a driving force from the first transmission means is transmitted; one or more transmission means to which a driving force from the second transmission means is transmitted; and third transmission means that is fixed to the second rotation shaft, to which a driving force from the one or more transmission means is transmitted, and rotates the second driving roller at a predetermined peripheral velocity ratio with respect to the first driving roller.SELECTED DRAWING: Figure 5
【課題】回転軸(第二回転軸)の軸方向に見たときのスペースを小さくできるようにする。【解決手段】駆動機構は、駆動源からの駆動力で回転する第一駆動ロールの第一回転軸に固定され、前記第一回転軸と一体に回転する第一伝達手段と、前記第一駆動ロールに対向する第二駆動ロールの第二回転軸に対して空転可能に設けられ、前記第一伝達手段からの駆動力が伝達される第二伝達手段と、前記第二伝達手段からの駆動力が伝達される一以上の伝達手段と、前記第二回転軸に固定され、前記一以上の伝達手段からの駆動力が伝達され、前記第一駆動ロールに対して予め定められた周速比で前記第二駆動ロールを回転させる第三伝達手段と、を備える。【選択図】図5 |
