Abstract
A sheet conveyance apparatus includes a first guide, a second guide, a conveyance roller pair including a first roller, and a second roller, a pressing member configured to press the second roller toward the first roller in a state where the second roller abuts against the first roller, a drive source configured to move the second roller between the first position and the second position, and a control unit configured to execute a separating process of controlling the drive source to position the second roller at the second position, and an abutment process of controlling the drive source so that the second roller moves from the second position to the first position. The second roller is positioned at the second position in a case where the second guide moves from the open position to the closed position.
Claims15
A sheet conveyance apparatus comprising:
- a first guide;
- a second guide configured to be movable between a closed position where the second guide faces the first guide and forms a conveyance path together with the first guide, and an open position where the second guide opens the conveyance path;
- a conveyance roller pair including:
- a first roller;
- and
- a second roller supported by the second guide and configured to nip a sheet together with the first roller so as to convey the sheet on the conveyance path, the second roller being movable, in a case where the second guide is located at the closed position, between a first position where the second roller abuts against the first roller and a second position where the second roller is separated from the first roller;
- a pressing member configured to press the second roller toward the first roller in a state where the second roller abuts against the first roller;
- a drive source configured to move the second roller between the first position and the second position;
- and
- a control unit configured to execute a separating process of controlling the drive source to position the second roller at the second position, and an abutment process of controlling the drive source so that the second roller moves from the second position to the first position,
- wherein the second roller is positioned at the second position in a case where the second guide moves from the open position to the closed position.
A sheet conveyance apparatus comprising:
- a first guide;
- a second guide configured to be movable between a closed position where the second guide faces the first guide and forms a conveyance path together with the first guide, and an open position where the second guide opens the conveyance path;
- a conveyance roller pair including:
- a first roller;
- and
- a second roller supported by the second guide and configured to nip a sheet together with the first roller so as to convey the sheet on the conveyance path while abutting against the first roller in a case where the second guide is located at the closed position;
- a pressing member configured to, when the second guide is located at the closed position, transition between a first state the pressing member presses the second roller toward the first roller with a first pressing force, and a second state where the pressing member presses the second roller toward the first roller with a second pressing force smaller than the first pressing force;
- a drive source configured to cause the pressing member to transition between the first state and the second state;
- and
- a control unit configured to execute a first pressure adjustment process of controlling the drive source so that the pressing member is in the first state, and a second pressure adjustment process of controlling the drive source so that the pressing member is in the second state,
- wherein the pressing member is in the second state in a case where the second guide moves from the open position to the closed position.
