Image recording apparatus and optical recording head

摘要

The terminations of the optical fibers are placed on columns L1 in the sub-scanning direction of a recording medium and fixed in such a way that columns L1 are stacked in multiple stages in the main scanning direction of the recording medium. In this way, the terminations form a matrix made up of 8 columns L1 in the sub-scanning direction of the recording medium and 16 rows L2 in the main scanning direction of the recording medium that intersect columns L1. The terminations of a plurality of optical fibers which belong to same columns L1 are arrayed with pitch P. With respect to a perpendicular that passes through center C of the termination of one optical fiber, center C of the termination that belongs to another column L1 and same row L2 at the same time is uniformly shifted by an amount of shift S in the sub-scanning direction. Thus, the present recording apparatus achieves improvements in both the recording speed and resolution at the same time.
