PROBLEM TO BE SOLVED: To accurately record an image onto photosensitive material at high speed. SOLUTION: A laser beam L modulated in accordance with image information is reflected alternately by two rotating reflection mirrors 58 and 60 in a spinner 40 after its optical axis is controlled to be moved by a specified amount in directions X and Y by a beam shift part 38, and guided to the photosensitive material S. In such a case, the moving direction of the laser beam L by the beam shift part 38 is controlled corresponding to the rotation of the mirrors 58 and 60, whereby the material S is scanned with the laser beam L by each mirror 58 or 60. Thus, efficient image recording is performed. |
