Problems solved by technology

[0006] In addition, such a problem is not limited to inkjet printers that use ultraviolet curable ink to print, but is a problem that is almost common in liquid ejection devices that eject photocurable liquid.

no. 1 approach

[0045] Below, refer to Figure 1 to Figure 6 A first embodiment in which a liquid ejecting device is embodied as an inkjet printer will be described.

[0046] figure 1 The illustrated printer 11 has a lower support base 13 provided in a main body casing 12 , and a transport motor 14 driven to transport a medium P such as paper in a transport direction Y to the support base 13 . In addition, the printer 11 has a guide shaft 15 extending above the support table 13 in the main body casing 12 along the direction perpendicular to the conveyance direction Y, that is, the scanning direction X. A carriage 16 supported in a reciprocating manner, and a carriage motor 19 that moves the carriage 16 along the guide shaft 15 .

[0047] A liquid ejection head 31 for ejecting an ultraviolet (UV) curable ink as an example of a photocurable liquid is provided on the lower surface of the carriage 16 . When the medium P is transported onto the support table 13 by driving the transport motor 1...

no. 2 approach

[0068] Next, refer to Figure 7 ~ Figure 10 A second embodiment in which a liquid ejecting device is embodied as a printer will be described.

[0069] In the present embodiment, at least one of the first irradiator 40 and the second irradiator 41 is moved in a direction intersecting the ejection direction (transportation direction Y) in which ink is ejected from the liquid ejection head 31 to the medium P. The relative positions of the irradiation ranges A1 and A2 on the medium P are changed. In addition, in order to change the relative position of irradiation areas A1 and A2 in this way, the direction which moves at least one of the 1st irradiator 40 and the 2nd irradiator 41 is called approaching separation direction C in this embodiment.

[0070] Figure 7 The carriage 16 of this embodiment is shown schematically. The drive part 44 provided on this carriage 16 has a structure which moves only the 2nd irradiator 41 among the 1st irradiator 40 and the 2nd irradiator 41 in ...

no. 3 approach

[0078] Next, refer to Figure 11 to Figure 14 A third embodiment in which a liquid ejecting device is embodied as a printer will be described.

[0079] In this embodiment, the relative positions of the irradiation ranges A1 and A2 on the medium P are changed by adjusting the directivity of at least one of the first irradiator 40 and the second irradiator 41 .

[0080] Figure 11 The carriage 16 of this embodiment is shown schematically. The driving unit 44 provided on the carriage 16 has a structure for adjusting the directivity of the second illuminator 41 among the first illuminator 40 and the second illuminator 41 . Specifically, the driving unit 44 has a motor, and has a conversion mechanism for causing the driving force of the motor to act on the second illuminator 41 in the rotation direction D that changes the directivity of the second illuminator 41 . In addition, the rotation direction D here means the direction which rotates the 2nd irradiator 41 so that the irrad...

Abstract

When a medium is located immediately under a distance sensor in printing, a controller of a printer acquires a distance from the medium to a first irradiator and a second irradiator in a direction orthogonal to a relative movement direction in which the medium moves relative to a liquid ejecting head, on the basis of a detection signal from the distance sensor. On the basis of the distance, the controller changes relative positions of irradiation ranges irradiated with light from the first irradiator and the second irradiator on the medium so as to define relative positions of the irradiation ranges such that the degree of overlapping between the irradiation ranges and the distance between the irradiation ranges do not increase significantly.

Description

technical field [0001] The present invention relates to liquid ejection devices. Background technique [0002] As one type of liquid ejecting device, there is known an inkjet type printer in which a photocurable (for example, ultraviolet curable) liquid is ejected from a liquid ejecting head toward a medium that is relatively moved relative to the head, The first light source unit and the second light source unit irradiate light (for example, ultraviolet rays) to the medium, thereby curing the liquid on the medium (for example, refer to Patent Document 1). [0003] However, the thickness of the media varies depending on the type of media. Since the thickness of the medium changes, when light is irradiated onto the medium ejected from the liquid ejection head, the distance L between the medium, the first light source unit and the second light source unit in the ejection direction changes. Furthermore, when the distance L changes, the relative position of the irradiation ran...
