PURPOSE:To apply non-contact optical recording to a recording body by a simple structure and to directly perform drawing without requiring post-treatment in a bright room by placing an optical recording body capable of directly drawing a detailed image without being passed through a developing process by scanning recording laser emitted from a semiconductor laser irradiation part on a recording body placing table. CONSTITUTION:A thermal color forming recording material 3 is formed by successively providing a thermal recording layer 23 and a transparent protective layer 20 on a support 24 and the thermal recording layer 23 is constituted of a binder mixed with a near infrared absorber 21 uniformly dissolved in a sensitizer and a thermal color forming material and other necessary various materials. The leading end of a laser irradiation part 7 is arranged above the optical recording material 3 at a distance of 0.5 mm - 2 cm so as to condense laser beam to the recording surface of the optical recording material 3 and can be made movable on the optical recording material 3 in an XY direction in a non-contact state. A cover glass 15 for protecting the interior of the irradiation part from external contamination is provided to the leading end part of the laser irradiation part. The irradiation part is converged to the optical recording material and operated according to a program to immediately form an image on the optical recording material directly. |
