Embodiment Construction

[0093] Hereinafter, the light irradiator and the head of the inkjet printer according to the embodiment of the present invention will be described.

[0094] (1) Light irradiator

[0095] The basic structure of the light irradiator of the present invention is provided with: at least one light source unit composed of a short arc discharge lamp and a reflector that reflects light from the discharge lamp, and light irradiated from the light source unit is incident and condensed and emitted It is composed of a cylindrical lens in the uniaxial direction, and condenses and irradiates light from the discharge lamp as a light irradiation area extending linearly on the light irradiation surface.

[0096] Fig. 1 is a cross-sectional view showing the basic structure of the light irradiator of the present invention, Fig. 1(a) is a cross-sectional view viewed from the axial direction of a cylindrical lens, and Fig. 1(b) is a view showing the condensing light from the cylindrical lens Section vi...

Abstract

The invention provides a light irradiation device that irradiates linearly focused light with high peak irradiance and excellent irradiance uniformity and an inkjet printer fitted with that light irradiation device that is capable of curing light-curable inks or other liquid materials with high efficiency. The light irradiated from discharge lamp (12) is reflected by reflector (13) of reflection surface with spinning paraboloidal and is irradiated to a cylindrical lens (17). The light incident to the cylindrical lens (17) is condensed at the direction normal to the axis direction of the cylindrical lens (17) and is emergences at the other surface. A light irradiation area (IA) linearly extending towards the axis direction of the cylindrical lens (17) is formed at the position of focus Fs of the cylindrical lens (17) on the photoirradiated surface. The light irradiation device is suitable to ink jet type printer using light hardening type inking style and increases the hardening treatment efficiency of ink.

Description

Technical field [0001] The present invention relates to a light irradiator and an inkjet printer. In particular, it relates to a light irradiator that forms a linear elongated light irradiation area in a light irradiation object and irradiates light, and sprays a photo-curing liquid material carrying the light irradiator onto a substrate to be deposited on the substrate Inkjet printers that record patterns such as images and circuits. Background technique [0002] At present, the inkjet recording method is used in various printing fields such as special printing of photographs, various types of printing, markings, and color filters, because images can be formed simply and inexpensively by gravure printing. . [0003] In an inkjet printer using this type of inkjet recording method, by appropriately combining inkjet heads that control fine dots, the color reproduction area, durability, and proper ejection of inks are improved, and the improvement is drastically improved Special pap...
