摘要： A sheet feeding device includes a feeder, a contact member, a movement restricting member, a moving mechanism, and control circuitry. The feeder is configured to feed a sheet. A leading end of the sheet in a feeding direction is to contact the contact member. The movement restricting member is configured to lock the contact member to restrict movement of the contact member from a contact position where the contact member contacts the sheet. The moving mechanism is configured to move the movement restricting member between a locking position and a lock releasing position. The contact member is configured to take the contact position by gravity or a biasing force of a biasing part. The control circuitry is configured to control the moving mechanism to move the movement restricting member to the lock releasing position and then to the locking position when a feeding operation of the sheet is finished.

摘要： A sheet stacker includes a sheet stack table on which a sheet is stacked and a sheet reversing section disposed above the sheet stack table. The sheet reversing section defines a sheet reverse passage to reverse a direction of conveyance of a sheet fed to the sheet reversing section. The sheet reversing section includes a first sheet guide to guide a bottom face of the sheet and a second sheet guide disposed downstream from the first sheet guide in a sheet conveyance direction in which the sheet is fed to the sheet reversing section. The second sheet guide to guide the bottom face of the sheet is attachable to and removable from an apparatus body.
