PROBLEM TO BE SOLVED: To provide a bearing device enabling attachment/detachment of a roller without requiring work using a tool and a sheet delivering device equipped with the bearing device. SOLUTION: The sheet delivering device 10 comprises a drive roller 11 for applying delivering force to a band-shaped sheet S, a pinch roller 12 pinching the sheet S between the pinch roller 12 and the drive roller 11, the bearing device 32 of the drive roller 11, and a drive means 19 for applying drive force to the drive roller 11. The bearing device 32 has a holding means 17 for holding a roller shaft 11B of the drive roller 11 and a bearing 15 for rotatably supporting the holding means 17. The holding means 17 includes a housing 28 for storing the roller shaft 11B and first and second one-way clutches 30, 31 arranged inside the housing 28. The clutches 30, 31 suppress the rotation of the roller shaft 11B in both directions and the roller 11 is rotated integrally with the holding means 17. COPYRIGHT: (C)2009,JPO&INPIT
