Title: Liquid discharge device
Inventor: KANZAKI TAKASHI
IPC: B41J2/01
Filed: 2018-01-15
Abstract: To suppress deviation of a landing position of ink caused by turbulence of an air flow.SOLUTION: A columnar roller 6, of which an axial direction is a scan direction orthogonal to a conveying direction, is arranged on an upstream side of an ink jet head 2 in the conveying direction of a recording paper P. The roller 6 rotates in a direction of moving to the conveying direction on a lower end of an outer circumference surface 11 of the roller. A traveling speed of the outer circumference surface 11 of the roller 6 is higher than a conveying speed of the recording paper P. With this structure, a part of an air flow, which is generated when the recording paper P is conveyed and flows in the conveying direction along the recording paper P, flows in a direction separating from the recording paper P along the outer circumference surface 11 of the roller 6. Thereby, the air flow flowing in the conveying direction along the recording paper P is prevented from flowing between the ink jet head 2 and the recording paper P.SELECTED DRAWING: Figure 2
