Inkjet recording apparatus

摘要

An inkjet recording apparatus includes a recording head that has an ink discharge surface and that discharges ink onto a recording medium, a wiper blade that cleans the ink discharge surface of the recording head, and a controller. The controller causes the wiper blade to wipe ink off the ink discharge surface by causing the wiper blade to be pushed against the ink discharge surface and move in a predetermined movement direction. The wiper blade includes a protrusion protruding in the predetermined movement direction. The protrusion has an ink retaining surface that faces the ink discharge surface at a predetermined distance while the wiper blade wipes ink off the ink discharge surface.

1. An inkjet recording apparatus comprising:
a recording head having an ink discharge surface and configured to discharge ink onto a recording medium; a wiper blade configured to clean the ink discharge surface of the recording head; and a controller configured to cause the wiper blade to wipe ink off the ink discharge surface by causing the wiper blade to be pushed against the ink discharge surface and move in a predetermined movement direction, wherein the wiper blade includes a protrusion protruding in the predetermined movement direction, the protrusion has an ink retaining surface that faces the ink discharge surface while the wiper blade wipes ink off the ink discharge surface, the ink retaining surface is
located apart from the ink discharge surface at a first predetermined distance during the wiper blade wiping ink on the ink discharge surface, andin contact with a front surface of the wiper blade at a second predetermined distance from an upper end of the wiper blade while the wiper blade is in contact with the ink discharge surface so as not to be bent, the front surface of the wiper blade moves the ink on the ink discharge surface while the wiper blade moves in the movement direction, and the protrusion has a groove extending in a direction perpendicular to a short direction of the ink discharge surface.
