Abstract
In a sheet feeding device, a feeding roller is driven and rotated to feed a sheet in a conveying direction of a sheet conveying path and a drive transmission mechanism transmits rotation drive force generated in a driving portion to the feeding roller. In this mechanism, a drive input gear having an inner space is arranged on a rotation axis supporting the feeding roller rotatably so as to rotate by the rotation drive force. A drive transmission gear arranged between the feeding roller and drive input gear on the rotation axis rotates and becomes slide-movable along the rotation axis between a first position transmitting the rotation drive force to the feeding roller and a second position cutting off the transmission of the rotation drive force to the feeding roller by the rotation drive force from the drive input gear to transmit the rotation drive force to the feeding roller.
