Inkjet recording apparatus
In an inkjet recording apparatus, a recording head has an ink ejection port through which ink is ejected, a cleaning liquid supplying portion has a cleaning liquid supply port through which cleaning liquid for cleaning an ink ejection surface having the ink ejection port, is supplied, and a cleaning member cleans the ink ejection surface by the cleaning liquid by moving while in contact with the ink ejection surface. The cleaning liquid supplying portion includes a main body portion and a protruding portion. The main body portion is disposed on an upstream side of the recording head in a moving direction of the cleaning member. The protruding portion protrudes from the main body portion toward a downstream in the moving direction, and covers, from below, lower ends of side surfaces of the recording head and the main body portion that face each other in the moving direction.
1. An inkjet recording apparatus comprising:
a recording head having an ink ejection port through which ink is ejected;
a cleaning liquid supplying portion having a cleaning liquid supply port through which cleaning liquid for cleaning an ink ejection surface is supplied, the ink ejection port being provided in the ink ejection surface; and
a cleaning member configured to clean the ink ejection surface by the cleaning liquid by moving while in contact with the ink ejection surface, wherein
the cleaning liquid supplying portion is formed independently of the recording head and includes:
a main body portion disposed on an upstream side of the recording head in a moving direction of the cleaning member; and
a protruding portion protruding from the main body portion toward a downstream in the moving direction, and covering, from below, lower ends of side surfaces of the recording head and the main body portion that face each other in the moving direction.
2. The inkjet recording apparatus according to claim 1 , wherein
the cleaning liquid supplying portion includes:
a first member including the cleaning liquid supply port and the protruding portion; and
a second member forming a storage space storing the cleaning liquid, together with the first member.
3. The inkjet recording apparatus according to claim 2 , wherein
the second member includes a concave portion having a lower opening, and
the first member is a plate-like member forming the storage space by covering the lower opening.
4. The inkjet recording apparatus according to claim 1 , further comprising:
a cleaning liquid cap portion configured to close the cleaning liquid supply port by covering the cleaning liquid supply port.
5. The inkjet recording apparatus according to claim 4 , further comprising:
an ink cap portion configured to close the ink ejection port by covering the ink ejection port.
6. The inkjet recording apparatus according to claim 5 , wherein
the cleaning liquid cap portion is separate from the ink cap portion.
7. The inkjet recording apparatus according to claim 1 , wherein
the main body portion includes:
a cleaning liquid supply surface in which the cleaning liquid supply port is formed; and
an inclined surface provided on the upstream side of the cleaning liquid supply surface in the moving direction, continuing from the cleaning liquid supply surface, and being inclined upward with respect to the cleaning liquid supply surface, wherein
before the cleaning member starts to be moved along the moving direction, a tip of the cleaning member is disposed at a predetermined movement start position that is set in a region located directly below the inclined surface and in a region located higher than a plane that includes the first cleaning liquid supply surface.
