Abstract: A liquid supply mechanism includes a tank configured to store liquid, a supply passage having an end connected to the tank so as to allow the liquid to flow, and an ejection member disposed on the supply passage so as to eject the liquid. The ejection member includes a filter, a check valve, and an ejection passage. The filter has a predetermined passage resistance to the passing liquid. The check valve is opened at a predetermined opening pressure for the passing liquid. The ejection passage allows the liquid to flow when the check valve is opened and ejects the liquid from an ejection port formed at a tip thereof. A pressure decompressed by the passage resistance of the filter is larger than the opening pressure of the check valve.

Abstract: An ink jet recording apparatus includes a recording head, a blade, and a cleaning liquid dispensing unit. The recording head includes a nozzle surface including a plurality of nozzles each having an ink outlet oriented downward, and is supported so as to move in an up-down direction. The blade wipes the nozzle surface, by moving in a predetermined moving direction in contact with the nozzle surface. The cleaning liquid dispensing unit stores therein cleaning liquid supplied from a cleaning liquid supply source, and supplies the cleaning liquid between a travel start position of the blade and the nozzle surface. The cleaning liquid dispensing unit includes a receptacle in which the cleaning liquid that has been supplied is stored, the receptacle having a top face open upward.

Abstract: An ink-jet recording apparatus includes: an ink-jet head with a nozzle plate; a blade that wipes the nozzle plate; a supply member provided upstream of the nozzle plate in a direction of wiping and capable of supplying a cleaning liquid to the blade upon contact with the blade; a link member that supports the supply member and rocks about a shaft below the supply member; a biasing member that biases the link member upstream in the wiping direction; and a pressing portion provided in conjunction with the ink-jet head and facing the supply member. While the ink-jet head is moved up, the supply member is kept away from the nozzle plate upstream in the wiping direction. When the ink-jet head moves down, the pressing portion presses down the supply member against a biasing force of the biasing member and, thus, the supply member moves downstream in the wiping direction.

Abstract: An image forming apparatus includes an inkjet head, a blade and a cleaning liquid supply member. The inkjet head is provided with a nozzle surface on which ink ejection ports of a plurality of nozzles are opened. The blade is movable in contact with the nozzle surface. The cleaning liquid supply member supplies a cleaning liquid to at least one of the nozzle surface and the blade. The cleaning liquid supply member has a lower surface. On the lower surface, an opening through which the cleaning liquid is discharged and a protrusion with which the cleaning liquid discharged through the opening can be in contact are formed.

Abstract: An inkjet recording apparatus includes a blade, a protruding member, a holder, a first biasing member, a supply member, and a second biasing member. The protruding member is provided integrally with the blade, and protrudes toward an inkjet head. The holder supports the protruding member and the blade. The first biasing member biases the protruding member and the blade toward the inkjet head around the shaft portion. The supply member is provided on a rear side of the nozzle surface in the moving direction, and is in contact with a tip end portion of the blade so that a cleaning liquid is supplied to the blade. The second biasing member biases the supply member toward the inkjet head. The blade is not in contact with the supply member when the protruding member and the supply member are not pushed from a side of the inkjet head.

Abstract: An inkjet includes a head unit, a blade, and a cleaning liquid supply member. The head unit is provided with a nozzle surface, and supported to be lifted and lowered. The blade is in contact with the nozzle surface and moves in a predetermined moving direction to wipe off the nozzle surface. The cleaning liquid supply member stores a cleaning liquid, and supplies the cleaning liquid between a moving start position of the blade and the nozzle surface. The cleaning liquid supply member has a plurality of supply ports provided between the moving start position of the blade and the nozzle surface. When a direction crossing to the moving direction is defined as a width direction, a width of the blade is set to “a”, and a width of a region where the supply ports are formed is set to “b”, then the next formula is established, a≤b.
