1. A liquid discharge apparatus comprising:
a liquid discharge device including:
a liquid discharge head including nozzles configured to discharge a liquid,
a carriage mounting the liquid discharge head, wherein the carriage is movable,
a wiper to wipe a nozzle surface of the liquid discharge head,
a wiper mover to hold and move the wiper between a facing position at which the wiper faces the nozzle surface and a standby position at which the wiper does not face the nozzle surface, and
a cleaning liquid applier to apply a cleaning liquid to the wiper, wherein the wiper mover holds the cleaning liquid applier,
wherein the carriage movably holds the liquid discharge head and the wiper mover as a single unit;
a carriage mover to move the carriage; and
a mounting table to mount a columnar member as an object to which the liquid is discharged from the liquid discharge head,
wherein the carriage is reciprocally movable in a vertical direction as a first direction, and the carriage mover reciprocally moves the carriage in a second direction along a tangent line of the columnar member in a plane defined by the first direction and a direction orthogonal to the first direction.
