Publication number: 20240132313Abstract: A sheet conveyance device includes a frame, first and second rollers, a roller shaft, an urging member, and a bearing. The bearing includes a holding portion to slidably hold the roller shaft and held by the frame. The holding portion is deformable. As viewed in a rotational axis direction of the roller shaft, a direction in which the urging member urges the second roller is defined as a first direction, a direction that is perpendicular to the first direction is defined as a second direction, and a region where the roller shaft is present in the second direction is defined as a first region. The frame holds the bearing so as not to be in contact with the holding portion in the first region downstream of a rotation center of the roller shaft in the first direction.Type: ApplicationFiled: October 18, 2023Publication date: April 25, 2024Inventor: YOSHIMI SUZUKI
