ABSTRACT:
A laser scanning apparatus having horizontal and vertical deflection means for deflecting n laser beams of the same wavelength modulated by n kinds of pattern information signal components in the horizontal and vertical directions. The n laser beams are spatially separated so that the pattern informations are directly drawn on a plurality of drawn media. Thus, pattern informations of different patterns can be drawn on the plurality of drawn media by one horizontal deflection means and one vertical deflection means, whereby the laser scanning apparatus can be made compact in size, light in weight and small in power consumption. Also, the pattern informations can be drawn with high coupling ratio (high light utilizing ratio and proper brightness) and high resolution.
