Patent number: 8746839Abstract: A fluid ejection apparatus ejects a fluid from a nozzle and includes a nozzle opening surface in which the nozzle is formed. A fluid removal unit removes fluid adhering to the nozzle opening surface. The fluid removal unit includes a plate-shaped wiper member that is formed from an elastic material. The wiper member moves from one end of the nozzle opening surface to the other as the ejection head or the wiper member moves while in a state where the wiper member makes contact with the nozzle opening surface and elastically deforms. A splash catching member is erected in front of the wiper member when the wiper member moving relative along the nozzle opening surface separates from the nozzle opening surface and returns to its original shape. The splash catching member catches objects that had been adhering to the nozzle opening surface and are scattered by the wiper member.Type: GrantFiled: February 16, 2010Date of Patent: June 10, 2014Assignee: Seiko Epson CorporationInventor: Takato Hayashi
