Claims

[Scope of utility model registration request]

In a printer equipped with a sealing/cleaning device for preventing ink from drying and removing clogging in the ink nozzles of an inkjet recording head, the sealing/cleaning device is provided.
The cleaning device includes a suction cup-shaped sealing/suction portion that is hermetically pressed against the nozzle opening surface of the inkjet recording head so as to contain all the nozzle openings therein, and is capable of creating a negative pressure in the internal space, and the nozzle opening. A sealing area equipped with a wiper for wiping the surface.
a cleaning head; and a drive mechanism that pivots or rotates the sealing/cleaning head around its predetermined axis and moves it back and forth in a straight line opposite the nozzle opening surface; The sealing/suction section is pressed against the nozzle opening surface of the inkjet recording head located opposite to the ink to prevent the ink from drying, and if necessary, the internal space is made into a negative pressure to prevent clogging of the ink nozzle. An inkjet printer characterized in that, after removal, the sealing/cleaning head moves back and forth in a straight line and rotates or rotates so that the nozzle opening surface is cleaned by the wiper.
