Compared with the prior art, the ink jet printer provided by the application, through the ink scraping device, the displacement driving mechanism 30 of the ink scraping device is connected with the ink scraping disc 20 through the folding and unfolding mechanism 40, when the displacement driving mechanism 30 is folded along the first direction F1 or the second direction F2 by driving the folding and unfolding mechanism 40, the folding and unfolding mechanism 40 drives the ink scraping disc 20 to move along the first direction F1 or the second direction F2, the setting of the folding and unfolding mechanism 40 can increase the movement amount of the ink scraping disc 20 along the first direction F1 or the second direction F2, the movement range of the ink scraping disc 20 in the first direction F1 is further increased, the stroke of the displacement driving mechanism 30 is not required to be increased, the displacement driving mechanism 30 is convenient to fix, and when the ink scraping device is not used, the space occupation of the ink scraping device is reduced by enabling the folding and unfolding mechanism 40 to be in a folding state.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, and alternatives falling within the spirit and principles of the present application.
