<p><P>PROBLEM TO BE SOLVED: To provide a technology which enables favorable exposure in a constitution in which a plurality of lens arrays are arranged in a longitudinal direction. <P>SOLUTION: This exposure head includes a first lens array which has first lenses at an end of one side of a first direction, a second lens array which has second lenses at an end of the other side opposite to the one side of the first direction and is arranged at one side of the first direction of the first lens array, first support members which support the first lens array, and second support members which support the second lens array. A distance between a first end side of one side of the first direction of the first lens array and the first support member is equal to a distance between a second end side of the other side of the first direction of the second lens array and the second support member. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
