<P>PROBLEM TO BE SOLVED: To shorten the time taken for drawing by decreasing a line interval of exposure heads, and suppress a component cost by making how to mount onto an apparatus body same for all the exposure heads in the drawing apparatus where the exposure heads are arranged over a plurality of lines. <P>SOLUTION: The exposure heads 30<SB>21</SB>to 30<SB>25</SB>in the second line are mounted in a direction where the exposure heads 30<SB>11</SB>to 30<SB>15</SB>in the first line have been turned 180°, and the exposure heads 30<SB>11</SB>to 30<SB>15</SB>in the first line and the exposure heads 30<SB>21</SB>to 30<SB>25</SB>in the second line are disposed in close vicinity to each other to the utmost. When a control signal input into a spatial light modulation element in the second line exposure heads is generated, image data are read in the order different from that when a control signal is generated into a spatial light modulation element of the first line exposure head, and a control signal is generated according to the direction of a spatial light modulation element. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
