an urging member configured to press the guide in the first direction toward the cover mask.
2. The cleaning device according to claim 1 , further comprising:
a stopper configured to limit movement of the guide in the first direction away from the cover mask, wherein
the guide comprises a protrusion, and
the stopper comprises an opening for accepting the protrusion.
3. The cleaning device according to claim 2 , wherein the stopper comprises a hole in which the protrusion fits.
4. The cleaning device according to claim 1 , wherein the guide is configured to move along a surface of the cover mask in a third direction orthogonal to the first and second directions while the predetermined gap is maintained.
5. The cleaning device according to claim 1 , further comprising:
a collection bottle fluidly connected to the suction port.
6. The cleaning device according to claim 1 , further comprising:
a suction pump fluidly connected to the suction port.
7. The cleaning device according to claim 1 , wherein the guide is configured to directly contact the side surface of the cover mask and position the suction port relative to the nozzle plate in the second direction.
8. The cleaning device according to claim 1 , further comprising:
a wiping blade configured to wipe the cover mask.
9. The cleaning device according to claim 8 , further comprising:
a holder configured to hold the wiping blade;
a holding member holding the holder and including the suction port;
a suction pump fluidly connected to the suction port; and
a collection container configured to collect liquid received via the suction port.
10. A liquid discharge recording apparatus, comprising:
a liquid discharge head comprising a nozzle plate and a cover mask, the nozzle plate including a plurality of nozzles and the cover mask being configured to cover a periphery of a surface of the nozzle plate; and
a cleaning device comprising:
a suction port configured to face the nozzle plate with a predetermined gap in a first direction between the suction port and the surface of the nozzle plate, the surface of the nozzle plate having a nozzle therein;
a guide configured to face the cover mask when the suction port faces the nozzle plate, the cover mask covering a periphery of the nozzle plate, the guide being moveable in the first direction away from the cover mask, the guide extending in a second direction beyond an outermost edge of the cover mask, and a portion of the guide extending in the first direction and engaging the outermost edge of the cover mask and a side surface of the cover mask to limit movement of the suction port in the second direction; and
an urging member configured to press the guide in the first direction toward the cover mask.
11. The liquid discharge recording apparatus according to claim 10 , wherein the cleaning device further comprises:
a stopper configured to limit movement of the guide in the first direction away from the cover mask, wherein
the guide comprises a protrusion, and
the stopper comprises an opening for accepting the protrusion.
12. The liquid discharge recording apparatus according to claim 11 , wherein the stopper comprises a hole in which the protrusion fits.
13. The liquid discharge recording apparatus according to claim 10 , wherein the guide is configured to move along a surface of the cover mask in a third direction orthogonal to the first and second directions while the predetermined gap is maintained.
14. The liquid discharge recording apparatus according to claim 10 , further comprising:
a collection bottle fluidly connected to the suction port.
15. The liquid discharge recording apparatus according to claim 10 , further comprising:
a suction pump fluidly connected to the suction port.
16. The liquid discharge recording apparatus according to claim 10 , wherein liquid discharge head is an ink jet head.
17. The liquid discharge recording apparatus according to claim 10 , wherein the liquid discharge head is a circulation type head.
