Abstract:
1. A sheet conveying apparatus for conveying a sheet supported by a sheet supporting member, the sheet conveying apparatus comprising: a conveying roller which contacts with the sheet supported by the sheet supporting member, at a predetermined pressure; and an arm which is disposed swingablly with one point as a supporting point, and rotatably supports an axis of the conveying roller at one end thereof, wherein a conveying roller supporting section, which supports the axis of the conveying roller of the arm, is located closer to the sheet supporting member side than the supporting point of the arm, and the supporting point of the arm is located closer to a downstream side in a sheet conveyance direction than the conveying roller supporting section of the arm, and, in a case in which rigidity of an oscillation system of the conveying roller is K [N/m], the distance between the supporting point of the arm and the roller supporting section of the arm is L [mm], and arm angle, which is formed between the sheet and a line segment connecting the supporting point of the arm to the roller supporting section of the arm on an assumed plane perpendicular to a direction of the axis of the conveying roller, is θ [deg], θ≦(Pse×K
