Patent ID: 8382275

Claim:
A printer comprising: an inkjet head having an ink nozzle surface facing in a downward direction; a transportation roller pair disposed at a position on an upstream side in a recording paper transportation direction from a printing position of the inkjet head that forms a nipping part between a first roller and a second roller disposed on a lower side of the first roller; a platen member having a guide surface that guides a recording paper and on which a plurality of ribs extend in the recording paper transportation direction and suction holes are formed, wherein the platen member includes an upstream-side end face opposite the second roller; and a vacuum unit that produces negative pressure for drawing air through suction holes, wherein the guide surface is formed by, a platen surface defined by a top surface of the ribs opposite the ink nozzle surface, and an upstream guide surface defined by the top surface of the ribs, wherein the upstream guide surface contiguous to the upstream side of the platen surface is an inclined surface that is inclined as it approaches the nipping part, wherein an upstream end part of the ribs protrude upstream from the upstream-side end faces towards the nipping part, and wherein the nipping part is a position offset height above a plane that extends along the platen surface.
