摘要 |
A first chamber has a plurality of first ventilation holes of a same size arranged on extended lines of a plurality of head arrays respectively. A second chamber faces the first chamber across the plurality of head arrays and has a plurality of second ventilation holes of a same size facing the plurality of first ventilation holes. Cross-sectional areas of an internal air flow passage in the first chamber at positions of the first ventilation holes decrease with an increase in a distance of the first ventilation holes from a first end of the first chamber. Cross-sectional areas of an internal air flow passage in the second chamber at positions of the second ventilation holes decrease with an increase in a distance of the second ventilation holes from a second end of the second chamber on the same side of the first end. |

1. An inkjet printer comprising:
a plurality of inkjet heads arranged in a plurality of head arrays; a first chamber having a plurality of first ventilation holes of a same size arranged on extended lines of the plurality of head arrays respectively, the first chamber extending in a direction orthogonal to the extended lines; a blow fan configured to send air into the first chamber from a first end of the first chamber; a second chamber facing the first chamber across the plurality of head arrays and having a plurality of second ventilation holes of a same size facing the plurality of first ventilation holes, the second chamber extending in the direction orthogonal to the extended lines; and a suction fan configured to suck air from a second end of the second chamber on a same side as a side of the first end of the first chamber, wherein the first chamber has a shape with cross-sectional areas of an internal air flow passage in the first chamber at positions of the first ventilation holes decreasing with an increase in a distance of the first ventilation holes from the first end, and the second chamber has a shape with cross-sectional areas of an internal air flow passage in the second chamber at positions of the second ventilation holes decreasing with an increase in a distance of the second ventilation holes from the second end. |
