Embodiment Construction

[0055] Hereinafter, embodiments of the light irradiation device of the present invention will be described based on the drawings.

[0056] In the form of this embodiment, the ultraviolet irradiation apparatus UR provided with the ultraviolet lamp 6 as a light source is illustrated as a light irradiation apparatus.

[0057] The ultraviolet irradiation device U R is installed on the printing head of the inkjet printing device for business use. When the printing head is scanned to form an image, it moves together with the printing head and irradiates ultraviolet rays to the UV ink of the formed image, thereby making the ink Instantly hardens and dries.

[0058] figure 1 The internal structure of the apparatus housing 1 of the ultraviolet irradiation apparatus UR is shown. The ultraviolet irradiation device UR mainly includes a blower unit 2 , a lamp unit 3 , a shutter unit 4 , and an exhaust unit 5 arranged in the device housing 1 .

[0059] These units are connected to each o...

Abstract

A light irradiation device is disclosed and makes it possible to securely hold a light-transmitting plate that transmits light emitted from a light source, the light-transmitting plate being mounted onto a light emission window while any increase in the number of components is minimized. The light irradiation device is provided with a shutter unit (4) having a shutter (4a) for switching between a state for allowing light from a light source (6) to be emitted through a light emission window (10) to the exterior of a device chassis, and a state for preventing the emission, wherein the position of a light-transmitting plate (11) in the shutter unit (4) is regulated. The light-transmitting plate transmits light emitted from the light source (6) mounted onto the light emission window (10).

Description

technical field [0001] The present invention relates to a light irradiation device, which includes a light source; a light output window for emitting the output light of the light source to the outside of the device frame; a board; and a shutter unit having a shutter that switches between a state in which light emitted from the light source is allowed to exit from the light exit window and a state in which light from the light exit window is prevented from exiting. Background technique [0002] One example of the light irradiation device, an ultraviolet irradiation device, is used in various applications such as hardening and drying of ink applied in an inkjet printing device, processing of semiconductor elements, and cleaning of various components. [0003] As a basic configuration of this light irradiation device, an ultraviolet lamp is provided in the device casing, and ultraviolet rays emitted from the ultraviolet lamp are emitted from an ultraviolet emission window form...
