Problems solved by technology

In the case where the second interval with a margin is set in this way, there is a possibility that the impact of the airflow generated between the head and the medium increases and the deviation of the landing position of the liquid droplets ejected from the head becomes large, so the recording quality may decrease. question

Embodiment approach

[0031] figure 1 It is a front view showing a schematic configuration of the recording device 1 according to the embodiment. figure 2 It is a block diagram showing a schematic configuration of the recording device 1 . image 3 is a schematic diagram showing an example of the arrangement of nozzles in the head 13 . Figure 4 It is an enlarged plan view of the recording unit 10 . Figure 5 It is an enlarged side view of the recording unit 10 . It should be noted, image 3 Shown is how the nozzle surface 13S of the head 13 is viewed from below. Figure 4 It shows how the recording unit 10 is viewed from above. Figure 5 It shows how the recording unit 10 is viewed along the Y axis.

[0032] First, refer to Figure 1 to Figure 5 The configuration of the recording device 1 will be described.

[0033] The recording device 1 includes a printer 100 and an image processing device 110 connected to the printer 100 . The printer 100 is an inkjet printer that records a desired ima...

[0094] Figure 15 It is an enlarged side view showing the recording unit 10 of the recording device 301 according to the second modification. The configuration of the recording device 301 according to Modification 2 will be described. In addition, the same code|symbol is attached|subjected to the same component part as embodiment, and the overlapping description is abbreviate|omitted.

[0095] The recording device 301 has an interval changing unit. Pitch Changing Sections A first pitch changing section 381 and a second pitch changing section 382 are respectively provided in the first area and the second area sandwiching the recording area PA in the main scanning direction.

[0096] The first interval changing portion 381 and the second interval changing portion 382 are provided so as to float up from the platen 15 and are disposed at positions overlapping the head 13 reciprocating in the main scanning direction when viewed from the Z-axis. The first interval changing part 3...

Abstract

The present invention addresses the problem of improving recording quality even when a second interval considering floating of a medium is set. A recording device 1 is provided with: a platen 15 that serves as a support unit to support a medium 5; a head 13 that relatively scans the platen 15 in a main scanning direction and ejects a liquid droplet onto the medium 5 supported by the platen 15; and an interval change unit that is provided in at least one of a first area and a second area sandwiching a recording area PA of the medium 5 therebetween in the main scanning direction. The interval change unit is provided so as not to overlap the recording area when seen from a direction orthogonal to a surface of the platen 15 that supports the medium 5. A first interval that is an interval between the interval change unit and the head 13 is narrower than a second interval that is an interval between the platen 15 and the head 13 in the recording area PA.

Description

technical field [0001] The present invention relates to recording devices. Background technique [0002] Conventionally, there is known a recording device that ejects liquid droplets from a head onto a medium to form dots to record an image or the like. In order to perform high-quality recording with such a recording apparatus, it is necessary to set the head and the medium at appropriate intervals. For example, Patent Document 1 discloses a recording device capable of increasing or decreasing the distance between a head and a platen supporting a recording material, that is, a platen gap, according to the thickness of a recording material serving as a medium. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-248535 [0004] However, in the recording device of Patent Document 1, the second gap as the platen gap is set with a certain margin in consideration of the floating of the medium in order to prevent so-called head friction in which the head comes into con...
