<p><P>PROBLEM TO BE SOLVED: To provide a line head module which has an improved durability by preventing light emitting elements from being deteriorated caused by heat. <P>SOLUTION: The line head module 101 is equipped with line heads 1 which include a plurality of aligned light emitting elements 3. The line head module performs exposure to a photo-conductor by light from the light emitting elements 3. The line head module is equipped with a support 10 which supports the line heads 1, and a passage 10H for circulation of a cooling medium which is set in the support 10 and thermally connected with the line heads 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
