Abstract:
1. An image recording apparatus for recording an image on a recording medium by relatively moving the recording medium and an inkjet head, said image recording apparatus comprising: an inkjet head; a table made of a planar member for mounting the recording medium; fixing means adapted to fixing the recording medium on said table with a suction groove formed on a surface of said table in communication with suction means via a suction hole; a moving mechanism for relatively moving said inkjet head and said table; a UV irradiation mechanism for irradiating ink transferred from said inkjet to said recording medium with ultraviolet rays; a position determining pin for determining a position of said recording medium on said table; a position determining pin lifting mechanism for lifting up and down said position determining pin relative to said table; and a control part for controlling said position determining pin lifting mechanism, wherein said control part controls said position determining pin lifting mechanism so as to maintain said position determining pin at a state of descending to a position where said position determining pin is not contact with said recording medium at least for a period of UV irradiation to said recording medium by said UV irradiation mechanism; wherein a cooling mechanism for cooling said table is arranged on a lower surface of said table; wherein said moving mechanism relatively moves said inkjet head and said table by causing reciprocating movement of said table in one direction and intermittent movement of said inkjet head; and wherein said cooling mechanism has a plurality of cooling water passages extended in a direction transverse to a reciprocating movement direction of said table and a cooling water circulation mechanism for allowing cooling water to pass through said plurality of cooling water passages on a lower surface side of said table.
