Printing apparatus

A printing apparatus comprising:

• a transport unit configured to transport a recording medium along a first direction;
• a printing head configured to discharge ink onto the recording medium;
• a recording medium support unit including a support surface and configured to support the recording medium by the support surface, the support surface facing the printing head with a transport path of the recording medium interposed between the printing head and the support surface;
• an air intake unit configured to suck air;
• and
• a suction region alteration unit, wherein
• the support surface is constituted by a surface extending along the first direction and a second direction orthogonal to the first direction, and includes a suction region provided with a plurality of suction holes,
• the air intake unit sucks air from the plurality of suction holes via a duct disposed at a surface on an opposite side from the support surface,
• the suction region alteration unit includes:
• a first guide member and a second guide member that are members extending in the second direction and that are disposed side by side in the first direction with the recording medium support unit interposed between the first guide member and the second guide member,
• a first mobile body configured to move along the first guide member,
• a second mobile body configured to move along the second guide member,
• a synchronization mechanism configured to synchronize movement of the first mobile body and movement of the second mobile body,
• a first blocking structure including a first suspension portion suspended between the first mobile body and the second mobile body, and a first sheet having flexibility and coupled to the first suspension portion, and
• a first accommodation unit accommodating at least a portion of the first sheet,
• a position, of the first suspension portion, facing the support surface is movable in the second direction together with the first mobile body and the second mobile body,
• the first sheet extends to one side in the second direction from the first suspension portion, and is larger than the suction region in the first direction,
• the first accommodation unit is disposed on the one side in the second direction of the recording medium support unit, and an opening of the first accommodation unit is at a position not overlapping the suction region in plan view, and
• the first sheet accommodated in the first accommodation unit is configured to be pulled out to a position overlapping a portion of the suction region in plan view by the first mobile body being moved in a direction away from the first accommodation unit.
