Abstract
Many holes are formed in a platen that supports a paper. A suction fan generates suction force through these holes to thereby bring the paper into close contact with a surface of the platen. Ink ejection regions to which printing heads eject ink are set on a paper supporting side of the platen. The holes are formed in other regions in the platen than regions corresponding to vicinities of longitudinal ends of the ink ejection regions.
Claims7
An inkjet printer comprising:
- a conveyance mechanism that conveys a printing medium;
- an ink ejecting member capable of ejecting ink to an ink ejection region extending in a direction substantially perpendicular to a conveyance direction of the conveyance mechanism;
- a supporting member that supports the printing medium in a region confronting the ink ejecting member and has the ink ejection region set on a printing medium supporting side thereof, no hole being formed in the ink ejection region, and at least one hole being formed in an area within a non ink ejection region other than the ink ejection region;
- and
- a suction member capable of sucking air through the hole from a printing medium supporting side of the supporting member to an opposite side thereof.
