Abstract:
1. An image recording device comprising: a support member which supports a recording medium by coming into contact with one surface of the recording medium; a transport section which transports the recording medium in a transport direction; a plurality of color ink heads, which are lined up in the transport direction and which each discharge photo curable color inks onto the other surface of the recording medium which is transported in the transport direction while being supported by the support member, the plurality of color ink heads including a first color ink head, which is disposed furthermost downstream among the plurality of color ink heads, and a second color ink head, which is disposed more to the upstream side in the transport direction than the first color ink head; a plurality of first irradiation units which are disposed between the color ink heads which are adjacent and which irradiate light onto the color inks which are discharged from the color ink heads on the upstream side in the transport direction onto the recording medium, the plurality of first irradiation units including a furthermost downstream first irradiation unit, which is disposed furthermost downstream among the plurality of first irradiation units and disposed between the second color ink head and the first color ink head with respect to the transport direction; a second irradiation unit which is disposed more to the downstream side in the transport direction than the plurality of color ink heads and which irradiates light which is stronger than the light which is irradiated by the first irradiation units onto the image which is formed using the color inks which are discharged by the plurality of color ink heads; a transparent ink head which is disposed more to the downstream side in the transport direction than the second irradiation unit and which discharges transparent ink onto the image which is formed on the other surface of the recording medium which is transported in the transport direction while being supported by the support member; and a third irradiation unit which is disposed more on the downstream side in the transport direction than the transparent ink head and which irradiates light which is stronger than the light which is irradiated by the first irradiation units to cure the transparent ink which is discharged onto the image using light irradiation, wherein the second irradiation unit is disposed adjacent to the first color ink head and adjacent to the transparent ink head, an interval in the transport direction between the second color ink head and the furthermost downstream first irradiation unit is smaller than an interval in the transport direction between the first color ink head and the second irradiation unit, an interval in the transport direction between the furthermost downstream first irradiation unit and the first color ink head is smaller than the interval in the transport direction between the first color ink head and the second irradiation unit, the interval in the transport direction between the second color ink head and the furthermost downstream first irradiation unit is smaller than an interval in the transport direction between the second irradiation unit and the transparent ink head, and the interval in the transport direction between the furthermost downstream first irradiation unit and the first color ink head is smaller than the interval in the transport direction between the second irradiation unit and the transparent ink head.
