Abstract
A sheet conveyor includes a drive roller, a retard roller forming a nip with the drive roller, a first torque limiter disposed coaxially with the retard roller and communicating with the retard roller, a first gear disposed coaxially with the retard roller, a drive train including a plurality of gears for receiving a driving force from the first gear, a second torque limiter, and an arm member including a contact portion located downstream of the drive roller in the conveyance direction. The arm member is movable between a first arm position to allow transmission of the driving force to the second torque limiter and a second arm position to interrupt transmission of the driving force to the second torque limiter. The arm member is configured to, as the sheet conveyed by the drive roller contacts the contact portion, move from the first arm position to the second arm position.
