PURPOSE:To reduce the size and cost of a color picture recorder by scanning optical beams from a plurality of semiconductor lasers disposed in an array on a ribbon coated with various types of heat sensitive inks in stripe state to impart fluidity and sublimation thereto. CONSTITUTION:Optical beams from a light source 1 in which light emitting points 7g, 7b, 7r of a plurality of semiconductor laser elements driven independently on the same wafer are formed via a collimator lens 2 in parallel beams, are reflected and deflected via a rotary polygonal mirror 3, and a spot is formed on a transfer ribbon 5 through a focusing lens 4. Thus, the dye adhered to the ribbon 5 is transferred to a recording sheet 6. Green dye 5g, blue dye 5b and red dye 5r are coated in stripe stage in lateral direction of the transfer ribbon 5, and the optical beams of the respective light emitting points 7g, 7b, 7r are scanned (deflected) on the dyes 5g, 5b, 5r. |
