PROBLEM TO BE SOLVED: To provide a scanning type plotting device which performs plotting connecting exactly images plotted by a plurality of scanning parts. SOLUTION: In a state where a body to be plotted 11 in the subscanning direction, when each scanning parts 30, 40 makes plotting light flux plot in the main scanning direction, lines corresponding to each scanning parts 30, 40 are drawn on the body to be plotted 11. Each line drawn by one scanning part 30 is drawn on the same straight line as the line corresponding to the line among each lines drawn by the other scanning part 40. Even when the space between each scanning parts are placed in the state deviated in the subscanning direction, by setting its deviationΔand the phase differenceϕof each polygonal mirrors 31, 41 as a prescribed value, an image plotted by one scanning part 30 and an image plotted by the other scanning part 40 are connected exactly. |
