Embodiment 1

[0050] First, refer to figure 1 The outline of the printing apparatus 1 according to Embodiment 1 of the present invention will be described.

[0051] The printing device 1 of the present embodiment is a printing device for printing an image on a printing medium M such as paper, cloth, or film, and is communicably connected to a computer (not shown), which is an external device. In addition, the printing apparatus 1 of this embodiment is configured to be capable of printing on a roll-shaped to-be-printed medium M, but may be configured to be capable of printing on a sheet-shaped to-be-printed medium M such as cut paper.

[0052] like figure 1 As shown, the printing apparatus 1 of the present embodiment includes a delivery unit 2 , in which a roll-shaped to-be-printed medium M is set and rotated in the rotation direction C so that the to-be-printed medium M can be sent out. The to-be-printed medium M is sent out to the first transport roller pair 9 through the delivery unit 2...

Embodiment 2

[0071] Next, refer to Figure 7 to Figure 11 The printing device 1 according to the second embodiment of the present invention will be described. Here, the configuration of the printing apparatus 1 of this embodiment is the same as that of the printing apparatus 1 of Embodiment 1 except for the frame 13 , the mounting portion 15 , the guide portion 16 , and the holding plate 227 . Therefore, descriptions of portions having a common structure, such as portions other than the frame 13 , the mounting portion 15 , the guide portion 16 , and the holding plate 227 , are omitted. In addition, structural components common to those of Embodiment 1 described above are indicated by the same reference numerals, and detailed explanations are omitted. In addition, in Figure 7 to Figure 11 In , one side of the width direction B in the temporary irradiation unit 7 of this embodiment is shown, but the other side of the width direction B also has the same structure.

[0072] like Figure 7...

Embodiment 3

[0083] Next, refer to Figure 12 The printing device 1 according to the third embodiment of the present invention will be described. Here, as Figure 12 As shown, in the printing device 1 of this embodiment, the side of the width direction B in the temporary irradiation unit 7 has the same structure as that of the printing device 1 related to the second embodiment, and the side of the width direction B in the temporary irradiation unit 7 The other side of B has the same structure as that of the printing device 1 according to the first embodiment. In addition, the configuration other than that is the same as that of the printing apparatus 1 of the first and second embodiments. Therefore, detailed description is omitted.

[0084] That is, the printing apparatus 1 of the present embodiment includes: a conveyance drum 3 that is a support portion of the medium M to be printed; The ink of the ultraviolet ray irradiating part 27 is provided at a position opposite to the conveying...

Abstract

The invention discloses a printing apparatus and a method of positioning an ultraviolet irradiation part. The ultraviolet irradiation part can be simply and accurately positioned. A printing apparatusincludes a supporting part for a printing medium, a head, an ultraviolet irradiation part that emits from an irradiation surface thereof ultraviolet light, a protrusion fixed to the ultraviolet irradiation part, a frame, an attaching part that is attachable to the frame with an attaching position thereof adjusted, and a guide part that is attachable to the frame and guides the adjustment of the attaching position of the attaching part with respect to the frame. The guide part includes first and second butted parts, and the attaching part includes a butting part having a width smaller than a spacing between the first and second butted parts, and a distance between the irradiation surface and the supporting part is a sum of a difference between the width of the butting part and the spacingand a protruding length of the protrusion from the irradiation surface.

Description

technical field [0001] The present invention relates to a printing device and a positioning method for an ultraviolet irradiation unit. Background technique [0002] Conventionally, a printing device is used that ejects ultraviolet curable ink from a head, irradiates ultraviolet rays from an ultraviolet irradiation portion to cure the ink, and forms an image on a conveyed printing medium. In such a printing device, when the ultraviolet rays irradiated from the ultraviolet irradiation unit reach the head, the ink in the nozzles of the head may be cured and the ejection stability may be reduced. Therefore, in such a printing device, the ultraviolet irradiating portion is positioned with high precision using a dedicated jig or the like so that the ultraviolet ray irradiated from the ultraviolet irradiating portion does not reach the head. Also, for example, Patent Document 1 discloses a printing apparatus that includes a shielding member in the ultraviolet irradiation unit in ...
