  • Patent number: 8777220
    Abstract: In general, in a sheet feeding device of embodiments, a shaft connects through an one-way clutch structure to a conveying roller, rotates in a first direction and a second direction opposite to the first direction, transmits the torque to the conveying roller to cause the conveying roller to rotate in the first direction if the shaft rotates in the first direction. The shaft does not transmit the torque to the conveying roller if the shaft rotates in the second direction. The shaft limits the rotation of the conveying roller in the second direction while the shaft is in a rotation-stop state. A controller has a second mode in which the shaft is rotated in a second direction to allow rotation of the conveying roller in the second direction.
