[57] ABSTRACT
A recording apparatus effects a recording operation by scanning a recording medium in a predetermined direction with a recording head provided with discharge openings for recording liquid. A cap member is capable of covering a face with discharge openings of said recording head. A transmission member causes said cap member to cover said face with discharge openings in response to a motion setting said recording head to a predetermined position; and engaging members consisting of a protruding part are provided on one of said recording head and a carriage supporting said head. The protruding part engages a receiving part for said protruding part formed on the other of said recording head and said carriage, wherein said protruding part and said receiving part mutually engage at two points when said cap member covers said face with discharge openings.
