Abstract: A stacker includes a medium stacking portion for receiving and stacking a medium processed and discharged by a processing unit, a medium butting portion for aligning the medium by contacting a leading end of the medium, and a paddle that includes a feeding portion and is for transporting the medium received by the medium stacking portion in a direction toward the medium butting portion by rotating. Furthermore, the stacker has a first mode in which the paddle stops in a state in which the feeding portion does not contact the medium on the medium stacking portion and a second mode in which the paddle stops in a state in which the feeding portion comes into contact with the medium on the medium stacking portion and is deformed.

Abstract: A suction mechanism for suctioning a loop transporting belt a medium processed by a processing unit, a rotation mechanism for rotating the transporting belt, a stacker for stacking the medium transported by the transporting belt, and a change mechanism for changing a movable area are included. The rotation mechanism, after suctioning the medium to the transporting belt to rotate in a first rotation direction to transport the medium in a first transport direction, rotates the transporting belt in a second rotation direction to transport the medium in a second transport direction to stack the medium on a stacker. The change mechanism narrows a movable area when the medium is transported in the second transport direction compared to an area when the medium is transported in the first transport direction.

Abstract: A recording portion has a nozzle surface. A first movement portion moves the recording portion in a first direction intersecting the nozzle surface. A second movement portion moves a first maintenance portion in a second direction along the nozzle surface. The recording portion is movable to a recording position at which recording is performed on a medium, and a first retreated position where the recording portion is retreated from the recording position. The first maintenance portion is movable to a maintenance position at which maintenance of the nozzle surface is performed and a second retreated position retreated from the maintenance position. When an error occurs, a control portion causes the recording portion to retreat away from the first maintenance portion in a first direction. Then, the first maintenance portion is caused to retreat in a second direction.
