<P>PROBLEM TO BE SOLVED: To reduce manufacturing costs by enhancing versatility in a light source array, a fiber, and a fiber bundle and simplifying the formation process of an exposure pattern. <P>SOLUTION: An exposure pattern formation method uses the light source array 4 where light sources 8 are placed side by side vertically and horizontally, and the fiber bundle 6, where output side edges of a plurality of fibers 11 in which each of input side edges is optically connected to each of the light sources 8 in a one-to-one relationship are bundled into one and output ends are placed side by side on an end face. In the exposure pattern formation method, each of the input ends of the fibers 11 is optically connected to each of the light sources 8 in a one-to-one relationship randomly, positions of the output ends of the fibers 11 for outputting light when each of the light sources 8 is lit successively are detected successively, the correlation between each of the light sources 8 and each position of the output ends of the fibers 11 is stored, and each of the light sources 8 is lit based on the correspondence, thus forming a desired exposure pattern on the end face of the fiber handle 6. <P>COPYRIGHT: (C)2007,JPO&INPIT |
