Abstract

An ink-jet recording apparatus according to this invention has an ink-head unit, a head holder, and a wiper unit. The ink-head unit extends in a direction that intersects at right angles to the direction a recording medium is transported, for a distance equal to or longer than the width of the recording medium. The head holder holds the ink-head unit. The ink-head unit has a nozzle surface having nozzles for ejecting ink. The wiper unit has a wiper blade, which wipes the nozzle surface.

Claims (23)

1. An ink-jet recording apparatus comprising:

a transporting mechanism which transports a recording medium;

an ink-head unit that has at least one ink head extending in a direction at right angles with a direction in which the recording medium is fed, the ink head having a nozzle surface in which a plurality of nozzles are arranged, through which ink is ejected to record an image, the ink head being at least as wide as the recording medium;

a head-holding unit which holds the ink-head unit to be opposed to the transporting mechanism; and

a blade unit which has a wiper blade for wiping the nozzle surface, wherein the blade unit is held by the head-holding unit;

a cap unit which caps the nozzle surface of the ink-head unit,

wherein the cap unit is opposed to the head-holding unit while the wipe blade wipes the nozzle surface, and

wherein the blade unit moves between the head-holding unit and the cap unit to wipe the nozzle surface.

2. An ink-jet recording apparatus comprising:

a transporting mechanism which transports a recording medium;

an ink-head unit that has at least one ink head extending in a direction at right angles with a direction in which the recording medium is fed, the ink head having a nozzle surface in which a plurality of nozzles are arranged, through which ink is ejected to record an image, the ink head being at least as wide as the recording medium;

a head-holding unit which holds the ink-head unit to be opposed to the transporting mechanism;

a blade unit which has a wiper blade for wiping the nozzle surface, wherein the blade unit is held by the head-holding unit; and

an accommodation unit provided at the head-holding unit for accommodating the blade unit, wherein the accommodation unit includes a door.

3. The ink-jet recording apparatus according to claim 2 , wherein the door remains closed while the blade unit is being accommodated in the accommodation unit.

4. An ink-jet recording apparatus comprising:

a transporting mechanism which transports a recording medium;

an ink-head unit that has at least one ink head extending in a direction at right angles with a direction in which the recording medium is fed, the ink head having a nozzle surface in which a plurality of nozzles are arranged, through which ink is ejected to record an image, the ink head being at least as wide as the recording medium;

a head-holding unit which holds the ink-head unit to be opposed to the transporting mechanism; and

a blade unit which has a wiper blade for wiping the nozzle surface, wherein the blade unit is held by the head-holding unit;

an accommodation unit provided at the head-holding unit for accommodating the blade unit; and

a cleaning member for cleaning the blade unit provided in the accommodation unit.

5. The ink-jet recording apparatus according to claim 4 , wherein the cleaning member hangs from the head-holding unit.
