It is sought to have a cap member sized to cover the entire lower surface of an ink jet head having numbers of nozzle heads, to improve intimacy of contact of the cap member with a carriage of the ink jet head, to obtain an enhanced airtightness between them and to enable the cap member to be manufactured roughly and at low cost. An arrangement is disclosed comprising: a cap member shaped in the form of a pan such as to cover all the nozzle heads of the ink jet head, the cap member having a peripheral wall and an upper end portion of the peripheral wall which extends over its entire perimeter; a seal member having a base portion and an elastically deformable seal portion, the seal portion having a tongue-like cross section as being thinner at its tip portion than at its root portion, the base portion of the seal member being fastened to the upper end portion over the entire perimeter of the peripheral wall of the cap member while the elastically deformable seal portion being then tilted outwards of the peripheral wall of the cap member; and a lifting unit for lifting the cap member and the seal member fastened thereto up and down so that the tip of the said seal portion may be moved over between a position at which it is brought into contact with and elastically deformed against the lower surface of a carriage of the ink jet head at the ink discharge position and a position at which it is spaced from the lower surface of the said carriage.
