Capping unit for ink jet recording unit

An ink jet recording head unit, comprising:

• an ink jet recording head having an electrical connecting terminal, and an ejection outlet surface provided with ejection outlets for ejecting ink and accommodating therein a liquid;
• and
• a capping unit mounted to the ink jet recording head during distribution,
• wherein the capping unit includes
• (i) a liquid-absorbing member provided with a projection for forming a gap between an area, in which the ejection outlets are formed, on the ejection outlet surface and the liquid-absorbing member, the projection contacting a periphery of the area on the ejection outlet surface, and
• (ii) a capping member including (i) an elastic portion for contacting a rear surface opposite from a surface on which the projection of the liquid-absorbing member is formed to press the liquid-absorbing member against the ejection outlet surface, (ii) a first engaging portion which is provided on a first surface so as to cover the electrical connecting terminal, the first engaging portion engaging with a first ink jet head engaging portion formed on the ink jet recording head to maintain a relative position between the capping member and the ink jet recording head against an elastic force of the elastic portion, and (iii) a second engaging portion which is provided on a second surface, the second engaging portion engaging with a second inkjet head engaging portion formed on the ink jet recording head to maintain a relative position between the capping member and the ink jet recording head against the elastic force of the elastic portion,
• wherein an interval between the first engaging portion and the liquid-absorbing member is larger than an interval between the second engaging portion and the liquid-absorbing member.
