Abstract
An inkjet printer 10 includes a platen plate 4 that has recess portions 41 and suction holes 42, and an inkjet type print head that has arrays of ink discharge nozzles right above the recess portions 41. Each suction hole 42 is set to have a first flow rate of air in a first suction path, and a second flow rate of air in a second suction path. The first suction path is made by the suction hole 42, and one of regions extending at a recess portion 41 of the platen plate 4, with the suction hole 42 intervening in between in a transfer direction. The arrays of ink discharge nozzles are disposed in the one region. The second suction path is made by the suction hole 42 and the other region at the recess portion 41. The second flow rate is smaller than the first flow rate.
