Patent ID: 7748838

Claim:
An inkjet drawing device for recording an image on a sheet-like image recording medium, comprising: a support for supporting said image recording medium; an inkjet head for ejecting photocurable ink as an ink droplet imagewise onto said image recording medium placed on said support, said inkjet head being disposed to be opposed to said support; a head moving mechanism for moving said inkjet head in a main scanning direction; a scanning active light irradiation section for scanning and irradiating said image recording medium with an active light beam in the main scanning direction to cure said photocurable ink ejected onto said image recording medium, said scanning active light irradiation section being disposed to be opposed to said support and to be on a transport downstream side of said image recording medium so that said scanning active light irradiation section is distant from said inkjet head by a predetermined distance; and a transport mechanism for transporting said image recording medium in a sub-scanning direction substantially perpendicular to the main scanning direction relative to said inkjet head, wherein said scanning active light irradiation section has: a point or substantially point active light source for emitting said active light beam; parallel light producing means for producing said active light beam emitted from said active light source as parallel light parallel to a recording surface of said image recording medium supported by said support; a scanning mirror which reflects said parallel light produced by said parallel light producing means toward a side of said image recording medium and which is movable in the main scanning direction; a mirror movement mechanism for moving said scanning mirror in the main scanning direction; and wherein said mirror movement mechanism has: two transport rollers disposed on both sides outside said image recording medium in the main scanning direction; an endless belt which is suspended between said two transport rollers and to which said scanning mirror is attached and inclined by a predetermined angle; and an irradiation window which is formed to be adjacent to a position where said scanning mirror is attached in a belt portion of said endless belt on the side of said image recording medium and through which irradiation light reflected by said scanning mirror is transmitted.
