<p>PROBLEM TO BE SOLVED: To facilitate the separation and assembly of a roller support shaft without increasing the number of part items. SOLUTION: A roller support shaft 26 and a drive shaft 22 are connected to each other, and this connecting part is supported on one bearing 25 held by a side plate 29. In this case, movement of the roller support shaft 26 in the axial direction is limited by the one bearing 25 to be engaged with the side plate 29 and the other bearing 27 to be engaged with a side plate 30. Conversely, the roller support shaft 26 can be removed from the side plates 29, 30 by moving the one bearing 25 along the drive shaft 22 by releasing the holding of the one bearing 25 to support the connecting part of the drive shaft 22 and the roller support shaft 26 and the side plate 29, and it is made possible to carry out the replacement of a paper feeding roller 6.</p> |
