1. A liquid discharge apparatus configured to discharge liquid, comprising:
a liquid discharge head having a discharge-surface in which a plurality of nozzles is formed; a cap including an inner bottom surface facing the discharge-surface and, in contact with the discharge-surface, to cover the plurality of nozzles; a movement mechanism configured to move at least one of the liquid discharge head and the cap to selectively take a first contact state for the cap to contact with the discharge-surface, a second contact state for the inner bottom surface of the cap to contact with the discharge-surface and to come closer to the discharge-surface than in the first contact state, and a separated state for the cap to separate from the discharge-surface; and a suction mechanism, wherein the plurality of nozzles include:
a plurality of first nozzles arrayed in one direction, anda plurality of second nozzles arrayed in the one direction and arranged in different positions from the plurality of first nozzles in an orthogonal direction orthogonal to the one direction; wherein the cap includes:
a first cap portion configured to cover the plurality of first nozzles, the first cap portion including a first inner bottom surface facing the discharge-surface, a first surrounding projection being elastically deformable and projecting from the first inner bottom surface toward the discharge-surface, and a first connective port to be connected with the suction mechanism;a second cap portion configured to cover the plurality of second nozzles, the second cap portion including a second inner bottom surface facing the discharge-surface, a second surrounding projection being elastically deformable and projecting from the second inner bottom surface toward the discharge-surface, and a second connective port to be connected with the suction mechanism; anda communicative portion configured to communicate the first cap portion and the second cap portion, wherein the communicative portion includes a part of the first surrounding projection of the first cap portion which is formed lower in the height from the inner bottom surface than the other portions of the first surrounding projections except the communicative portion, wherein the first cap portion is configured to seal up a first space between the first cap portion and the discharge-surface by causing the whole first surrounding projection to contact with the discharge-surface in the second contact state, wherein the second cap portion is configured to seal up a second space between the second cap portion and the discharge-surface by causing the whole second surrounding projection to contact with the discharge-surface in the second contact state, and wherein the part of the first surrounding projection of the communicative portion is separated from the discharge-surface in the first contact state, and contacts with the discharge-surface in the second contact state, and wherein the first and second cap portions and the communicative portions are configured to seal up the first and second spaces such that the first space is communicated with the second space via the communicative portion, in the first contact state. |
