Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem that an offensive smell is produced in the vicinity of a printer because an offensive smell removing means is not provided at a part of an offensive smell source, e.g. the vicinity of a print head stuck with UV-curing ink not yet cured, or the vicinity of a UV irradiator producing an offensive smell at the time of curing the UV-curing ink. <P>SOLUTION: The printer using UV ink and comprising a single or a plurality of print heads ejecting UV-curing ink, a UV irradiator for curing the UV-curing ink, and a UV irradiator cooling duct is further provided with a cover covering the print heads and the UV irradiator, and an exhaust duct fixed to the cover. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus using UV ink.

[0002]

2. Description of the Related Art A printing apparatus using UV ink includes a print head for ejecting UV ink which is cured by ultraviolet rays, a UV irradiation device for curing the UV ink immediately after the print head, and a U irradiation device.
It is generally composed of a suction blower connected to the V irradiation device cooling duct and the UV irradiation device cooling duct, and a print medium conveying means.

[0003]

As described above, the conventional U
In a printing apparatus using V ink, a portion that is a source of odor generation, such as the vicinity of a print head to which UV ink before UV curing adheres and the vicinity of a UV irradiation device that generates odor when UV ink is cured by ultraviolet rays, No odor removing means was provided, and odor was generated near the device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a printing apparatus using a UV ink, which is provided with an odor removing means to remove the UV ink odor.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a single or a plurality of print heads for ejecting UV ink that is cured by ultraviolet light, a UV irradiation device for curing the UV ink, and a UV irradiation device cooling duct. In a printing device using UV ink having a UV irradiation device cooling duct,
It is characterized by comprising a cover for covering the print head and the UV irradiation device, and an exhaust duct attached to the cover.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In FIG. 1, the printing device includes a print head 1 for ejecting UV ink, a UV irradiation device 3, a cooling duct 4 of the UV irradiation device 3, a suction blower 6 connected to the cooling duct 4, a cover for covering the print head 1 and the UV irradiation device 3. 7, an exhaust duct 5 attached to the cover 7, a suction blower 6 connected to the exhaust duct 5, a print medium conveying unit 8 and a housing 9.

The means for removing the odor of the UV ink in the above structure will be described below. The sources of odors in a printing apparatus using UV ink are the vicinity of the print head 1 to which UV ink before UV curing adheres, and UV that produces odor when UV ink is cured by UV rays.
It is in the vicinity of the irradiation device 3. Therefore, as in the above configuration, the print head 1 and the UV irradiation device 3 are covered with the cover 7, and the odor is removed by the exhaust duct 5 attached to the cover 7 and the suction blower or the suction fan 6 as a suction unit connected to the exhaust duct 5. By discharging it to the outside, it is possible to remove the odor of the UV ink.

FIG. 2 shows a second embodiment. In FIG. 2, by connecting the exhaust duct 5 and the UV irradiation device cooling duct 4, a suction blower or a suction fan 6 as a suction means.
It becomes possible to make only one, and an inexpensive system can be constructed.

FIG. 3 shows a third embodiment. By attaching the odor removing member 10 to the exhaust duct 5 and the UV irradiator cooling duct 4, it is not necessary to discharge the odor to the outside, and an inexpensive system is constructed. It becomes possible to do. Further, in the configuration of FIG. 3, the same effect can be obtained by using an aromatic agent instead of the odor removing member 10.

[0010]

As described above, according to the present invention, the print head and the UV irradiating device, which are sources of odor, are covered with a cover in the printing apparatus, and the exhaust duct and the odor removing member are installed on the cover. UV capable of removing ink odor
A printing device using ink can be provided.
