Patent ID: 8113502

Claim:
A sheet feeding device comprising: an arm member that is provided with a drive shaft at a base end thereof, the arm member being configured to swingably rotate around the drive shaft in accordance with an amount of a stacked sheets; a feed roller that is disposed at a leading end of the arm member, the feed roller feeding an uppermost sheet of the stacked sheets by being rotated while pressed on the uppermost sheet; and a transmission mechanism that is provided with a plurality of transmission rollers that transmit power provided from the drive shaft to the feed roller, wherein each of the transmission rollers is provided with a spindle that protrudes from both side faces thereof along a rotational axis, wherein the arm member is provided with a plurality of pairs of bearing members for the respective transmission rollers, each of the pairs of the bearing members being faced with each other and being monolithically formed on the arm member, wherein each of the bearing members is formed with an opening that allows the respective transmission rollers to be attachable in a direction orthogonal to the rotation axis, and the bearing members comprise a first bearing member rotatably supporting a first transmission roller and a second bearing member rotatably supporting a second transmission roller, the second bearing member adjacent to the first bearing member, wherein the opening of the first bearing member opens in a first direction and the opening of the second bearing member opens in a second direction opposite to the first direction, and wherein at least one of each of the pairs of the bearing members is formed to be elastically bendable in a direction to which the rotation axis extends.
