First claim
Opening claim text (preview).
What is claimed is: 1. A head cleaner for a liquid discharge apparatus, the head cleaner comprising: a first wiper to wipe, in a wiping direction, a nozzle face of a head that discharges liquid from nozzles formed on the nozzle face; and a second wiper to wipe the nozzle face of the head, wherein the first wiper is belt-shaped, and the second wiper is a blade and is configured to be moved between a wiping position where the second wiper wipes the nozzle face after the first nozzle wipes the wiper face and a cleaning position where the second wiper does not contact the nozzle face and is cleaned by the first wiper. 2. The head cleaner according to claim 1 , wherein the second wiper is retractable to a retracted position where the second wiper does not contact the nozzle face when the first wiper wipes the nozzle face. 3. The head cleaner according to claim 1 , further comprising a movable platform that mounts the first wiper and the second wiper, wherein the movable platform moves relative to the head in the wiping direction. 4. The head cleaner according to claim 1 , further comprising a guide roller that guides a conveyance of the first wiper, wherein the second wiper faces the guide roller via the first wiper at the cleaning position. 5. The head cleaner according to claim 4 , wherein the guide roller has an uneven shape. 6. The head cleaner according to claim 1 , wherein the first wiper is conveyed in a direction from upstream to downstream in the wiping direction of the first wiper, and the cleaning position of the second wiper is disposed upstream of a contact position where the first wiper contacts the nozzle face of the head. 7. The head cleaner according to claim 1 , wherein the second wiper is disposed upstream of the first wiper in the wiping direction. 8. The head cleaner according to claim 1 , wherein the first wiper is conveyed in a direction from downstream to upstream in the wiping direction of the first wiper. 9. The head cleaner according to claim 1 , further comprising: a feeding roller to feed the first wiper to the nozzle face of the head; and a shield disposed in a space between the feeding roller and the first wiper. 10. The head cleaner according to claim 9 , wherein the shield advances and retracts in the wiping direction. 11. A maintenance device for a head that discharges liquid from nozzles, the device comprising: a cap to cap the head; and the head cleaner according to claim 1 . 12. A liquid discharge apparatus comprising: a head to discharge liquid from nozzles; and the head cleaner according to claim 1 .
