Problems solved by technology

[0008] On the other hand, if the tension applied to the medium is increased in order to solve this problem, there is a problem as follows: when the medium is conveyed by the pinch rollers, excessive tension applied to the medium by the downstream rollers, Therefore, it is impossible to use the pinch roller for accurate conveying

Abstract

The invention provides an ink jet recorder which is capable of applying desirable tension to medium even when air conveying distance of the medium is great, so as to properly main gap between a recording head and the medium and enables high-definition record. The ink jet recorder (1) comprises a recording head (60) for ejecting liquid to the medium, a medium conveying mechanism (30) for clamping the medium and conveying the medium to predetermined conveying direction, a tensile roller (7) arranged on the downstream of the medium conveying mechanism in the conveying direction to apply constant tension to the medium in the supplying direction, and a brake roller (8) arranged on the upstream of the medium conveying mechanism in the conveying direction to apply constant tension to the medium in the opposite direction. The medium is conveyed in the air between the medium conveying mechanism and the tensile roller, and the liquid is ejected from the recording head to the medium for recording.

Description

technical field [0001] The present invention relates to an inkjet recording device, and more specifically, to an inkjet recording device that performs recording by ejecting a liquid onto a medium from a recording head mounted on a carriage that scans the medium. Background technique [0002] Conventionally, various configurations are known for inkjet recording devices (inkjet printers) that eject ink from nozzles of a recording head to record (print) desired characters and graphics on a medium (recording medium). [0003] In the case of an inkjet recording device using a cloth or a resin sheet as an example of a medium, it is important to achieve high-quality printing without causing warping, deformation, or wrinkles on the medium. [0004] The technique described in Patent Document 1 is disclosed as a conventional example of an inkjet recording device that prints on cloth. More specifically, it is a technique in which the tension roller is rotated synchronously with the su...
