Sheet feeding roller holding mechanism

摘要

A sheet feeding roller holding mechanism includes a sheet feeding roller which is detachably mounted on one end of a sheet feeding shaft. A body frame holds the other end of the sheet feeding shaft. The sheet feeding shaft is supported by a supporting member at the end of the shaft proximate the body frame, and a plate part is mounted to the body frame to support the supporting member. The body frame further supports a vibration preventive member. A part of the vibration preventive member abuts on a predetermined portion of the plate part, the supporting member or the sheet feeding shaft in a manner so as to prevent deformation. The vibration preventive part may include an elastic member. This roller holding mechanism may be used in an image forming apparatus.
