PROBLEM TO BE SOLVED: To improve assembling performance, while surely feeding a recording object medium in an image recording part by eliminating damage such as shaving of a bearing part, by smoothly rotating a driven roller 51, without adding fabrication to a support shaft 53 of the driven roller 51 pressed to a driving roller for carrying paper P. SOLUTION: The bearing part for journaling both end parts of the support shaft 53 for rotatably journaling the driven roller 51, is composed of a U-shaped groove type first bearing part 57a for supporting both end parts of the support shaft 53, and a second bearing part 57b for preventing drop out by restricting the other side surface among the outer periphery in both end parts of the support shaft 53; and is constituted so that a shaft irrotational member 589 is restricted by the second bearing part 57b by fitting the shaft irrotational member 59 to at least one end part of the support shaft 53.
