Abstract:
1. A liquid discharge apparatus comprising: a liquid discharge head in which a plurality of discharge ports for discharging a liquid are arranged in a first direction; a transport mechanism which is configured to transport a recording medium in a second direction perpendicular to the first direction; a platen which is provided opposingly to the plurality of discharge ports of the liquid discharge head and configured to support the recording medium to be transported by the transport mechanism, the platen having an opening which is formed so that the liquid, which is discharged from the plurality of discharge ports, passes therethrough, and an auxiliary support portion which is provided to be laid across a part of the opening so that the recording medium, which is to be transported across a position overlapped with the opening, is supported; a liquid receiving member which is provided on a side opposite to the liquid discharge head with respect to the platen and configured to receive the liquid discharged from the plurality of discharge ports of the liquid discharge head; a movement mechanism which is configured to move at least the auxiliary support portion of the platen between a first position and a second position separated in the first direction from the first position; and a control unit which is configured to control at least the liquid discharge head and the movement mechanism, wherein the liquid discharge head includes: a first area which is opposed to the auxiliary support portion and a second area which is opposed to the opening and which is different from the first area, in a state in which the auxiliary support portion is positioned at the first position; and a third area which is opposed to the auxiliary support portion and a fourth area which is opposed to the opening and which is different from the third area, in a state in which the auxiliary support portion is positioned at the second position, and wherein the control unit is configured to: control the movement mechanism so that the first area is included in the fourth area in the state in which the auxiliary support portion is positioned at the second position and the third area is included in the second area in the state in which the auxiliary support portion is positioned at the first position; control the liquid discharge head in the state in which the auxiliary support portion is positioned at the first position so that the liquid is discharged toward the liquid receiving member from the discharge ports of the plurality of discharge ports included in the third area; and control the liquid discharge head in the state in which the auxiliary support portion is positioned at the second position so that the liquid is discharged toward the liquid receiving member from the discharge ports of the plurality of discharge ports included in the first area.
