<p><P>PROBLEM TO BE SOLVED: To provide a line head for positioning the center line of a light emitting element line provided to a substrate and the reference line of the reference pin provided to the case of the substrate. <P>SOLUTION: A glass substrate 62 is provided with a light emitting section 63 having a plurality of light emitting elements arranged in the main scanning direction and is fixed to the case 60 with fixing sections 87a to 87d, wherein 68 represents a screw insertion hole and 69 a positioning pin. The reference pins 88, 89 are provided at both ends in the main scanning direction of the case 60. When the center line CLA of the light emitting element line of the light emitting section is shifted by a length L in the sub-scanning direction relative to the reference line CLB of the reference pins 88, 89, a means for positional adjustment of the glass substrate in the sub-scanning direction is provided, to execute the positional adjustment of the center line of the light emitting element line and the reference line. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
