Problems solved by technology

[0004] However, when doing this, a part of the cleaning liquid sprayed by the cleaning liquid spray nozzle is not applied to the wiping sheet, but scatters to the surroundings, so it is applied to peripheral devices other than the wiping sheet, such as a droplet discharge head and a sheet conveying device. , wasting the cleaning solution in vain, and due to the nature of the solvent used as the cleaning solution, it has a bad effect on the device

Abstract

A wiping unit is provided that wipes a droplet discharge head included in a droplet discharge unit and reduces the likelihood or prevents a cleaner to be sprayed to a wiping sheet from getting dispersed and adhering to peripheral units. A wiping unit (100) included in a droplet discharge unit (3) is provided with a charged electrode (203), an absorption electrode (204), and a static elimination brush (207). A cleaner sprayed by a cleaner spray head (161) is electrically charged by the charged electrode (203). The charged cleaner is absorbed toward the absorption electrode (204), and adheres to a wiping sheet (101) that is placed just before the absorption electrode. Accordingly, it is possible to reduce the likelihood or prevent the cleaner from getting dispersed and adhering to peripheral units.

Description

technical field [0001] The present invention relates to a wiper device for a droplet discharge head in a droplet discharge device (drawing device) using a droplet discharge head typified by an inkjet head, a droplet discharge device having the wiper device, an electro-optical device, and an electro-optical device. Manufacturing methods and electronic instruments. Background technique [0002] It is known that a conventional wiping device includes a wiping device equipped with a pressing member that relatively presses the wiping sheet onto the nozzle surface of the droplet ejection head, and a sheet conveying device that conveys the wiping sheet via the pressing member. Next, while transporting the wiping sheet, the wiping device and the sheet conveying device are integrally moved in a predetermined wiping direction parallel to the nozzle surface, and the nozzle surface is wiped with the wiping sheet (for example, refer to Patent Document 1). [0003] [Patent Document 1] Jap...
