Abstract:
1. An inkjet recording apparatus, comprising: a conveying belt that has opposite front and rear surfaces and a plurality of through-holes extending through the conveying belt from the front surface to the rear surface thereof, the conveying belt conveying a recording medium in a conveying direction with the recording medium placed on the front surface thereof; an inkjet head that has a nozzle surface provided with a plurality of nozzles and disposed opposite to the front surface of the conveying belt; a plate-like conveying platen disposed opposite to rear surface of the conveying belt and provided with a plurality of air circulation parts, each of which includes a long groove opened toward the conveying belt and formed in a longitudinal direction following the conveying direction, and a hole that penetrates in a thickness direction from a part of a bottom surface of the long groove, the air circulation parts being arrayed in the conveying direction and a width direction perpendicular to the conveying direction; and a negative pressure generating part that generates negative pressure to suction the recording medium through the air circulation parts of the conveying platen and the through-holes of the conveying belt and adsorb the recording medium onto the conveying belt, wherein the conveying platen has an opposed region that faces the nozzle surface, a part of the long groove is provided in the opposed region, and the hole is provided only in a region other than the opposed region.
