PROBLEM TO BE SOLVED: To allow a functional liquid drop discharge head immediately to face a wiping unit without providing a protective cover between a suction unit and a wiping unit and without making the functional liquid drop discharge head on stand-by at the position of a suction unit after suction treatment. SOLUTION: The maintenance apparatus is provided with the suction unit 61 sucking a functional liquid from the functional liquid drop discharge head 17, the wiping unit 62 disposed parallel to the suction unit 61 and for wiping the nozzle surface 53 of the functional liquid drop discharge head 17 with a wiping sheet 81, and a maintenance system moving means 13 for moving the functional liquid drop discharge head 17 in the parallel direction to the suction unit 61 and the wiping unit 62. In the maintenance apparatus 4, the functional liquid drop discharge head 17 is suction-treated and after that, moved from the suction unit 61 to the wiping unit 62 to be wiping-treated. A wiping sheet 81 faces below the suction unit 61 to partially overlap the suction unit 61 in the parallel direction. COPYRIGHT: (C)2007,JPO&INPIT
