Abstract
A recording apparatus includes a motor that is a common driving source for a first roller pair, a second roller pair, and a suction pump. A clutch is provided between a first power transmission section that transmits power of the motor to the first roller pair and the second roller pair and, of the second roller pair, a drive roller driven by the power of the motor. The clutch transmits the power of the motor when the motor rotates in a forward rotation direction and interrupts the transmission of the power of the motor when the motor rotates in a reverse rotation direction.
Claims9
A recording apparatus comprising:
- a conveyance path for conveying a medium;
- a recording head configured to perform recording on the medium in the conveyance path;
- a first roller pair provided upstream of the recording head in the conveyance path and configured to convey the medium;
- a second roller pair provided downstream of the recording head in the conveyance path and configured to convey the medium;
- a cap facing the recording head;
- a suction pump coupled to the cap;
- a motor that is a common driving source for the first roller pair, the second roller pair, and the suction pump;
- a first power transmission section configured to transmit power of the motor to the first roller pair and the second roller pair;
- a second power transmission section configured to set, as a forward rotation direction, a rotation direction of the motor at a time when the medium is conveyed downstream by the first roller pair and the second roller pair and transmit the power of the motor to the suction pump when the motor rotates in a reverse rotation direction opposite to the forward rotation direction;
- and
- a clutch provided between, of the second roller pair, a drive roller driven by the power of the motor and the first power transmission section, wherein
- the clutch transmits the power of the motor when the motor rotates in the forward rotation direction and interrupts the transmission of the power of the motor when the motor rotates in the reverse rotation direction.

- the second roller pair includes:
- a drive roller driven by the motor;
- and
- a driven roller driven to rotate while nipping the medium between the driven roller and the drive roller,
- the driven roller is rotatably supported by a movable frame,
- the movable frame is displaceable to a first position where the driven roller is capable of nipping the medium between the driven roller and the drive roller and a second position where the driven roller separates from the drive roller, and
- the movable frame is disposed at the first position when the motor rotates in the forward rotation direction and is disposed at the second position when the motor rotates in the reverse rotation direction.
