Abstract: A sheet conveyance apparatus includes a roller pair having first and second rollers, a roller holder having first and second guided portions, and a guiding portion having first and second guides. The first and second rollers can take a first state where the first roller contacts the second roller with a predetermined force and take a second state where the predetermined force is reduced. A first direction in which the first guide guides the first guided portion is inclined relative to a second direction in which the second guide guides the second guided portion. When viewed in a rotational axis direction of the first roller with the first and second rollers in the first state, an angle formed by a straight line passing through rotational centers of the first and second rollers and the first direction is smaller than an angle formed by the straight line and the second direction.

Abstract: A conveyance device to convey a sheet includes an apparatus main body including a regulating portion, an opening/closing door including a first guide portion, and a conveyance guide supported by the opening/closing door and having a second guide portion and a regulated portion. The opening/closing door moves relative to the apparatus main body between an open position and a closed position where the conveyance guide is placed between the apparatus main body and the opening/closing door. When the conveyance guide pivots in an away direction where the second guide portion moves away from the first guide portion with the opening/closing door in the open position, the regulated portion contacts the regulating portion to regulate rotation of the conveyance guide in the away direction. The second guide portion and the regulated portion are on one side of a pivot axis in a direction that is perpendicular to a pivot axis direction.
