Abstract: An alignment with a liquid jet head can easily be achieved, and surfaces of a jet plate and a guard member and an inside of an opening part of the guard member can be cleaned without injuring the jet plate even when side surfaces of the liquid jet head are not exposed, and a part of the jet plate is not exposed by the guard member. A cleaning device for an inkjet head includes a holder, and the holder includes a jet section which jets a cleaning liquid toward at least one of a nozzle plate and a nozzle guard, a contact part which makes contact with a surface of the nozzle guard provided with the opening part, and a protruding part which is inserted into the opening part in a non-contact state with the nozzle plate, and which guides the holder along a longitudinal direction of the opening part.

Abstract: There is provided a cleaning device for a liquid jet head which can efficiently clean a jet plate attached with a guard member while preventing cleaning liquid from being leaked along an opening of the guard member. The cleaning device for the inkjet head includes a holder moving relatively to the inkjet head, wherein the holder includes a jet section for jetting the cleaning liquid toward a nozzle guard of the inkjet head, a wipe part which has a width in a width direction perpendicular to a moving direction of the holder smaller than a width of an opening of the nozzle guard, and which wipes a nozzle plate due to a movement of the holder, a first suction section disposed ahead of the jet section and the wipe part in the moving direction of the holder, and a second suction section disposed posterior to the jet section and the wipe part in the moving direction of the holder.
