Abstract
PURPOSE:To correct a cylindrical lens effect obtained by an acousto-optical deflecting element by a simple constitution, by bringing a distance extending from the acousto-optical deflecting element to the cylindrical lens, to a variable control. CONSTITUTION:The titled device is provided with an acousto-optical deflecting element 1, a cylindrical lens 13 for receiving a light beam L2 emitted from the acousto-optical deflecting element 1, and driving control means 12, 20-22 for bringing a distance (d) extending from the cylindrical lens 13 to the acousto- optical deflecting element 1 to a variable control. That is, by bringing the distance (d) extending from the cylindrical lens 13 to the acousto-optical deflecting element 1, to a variable control, a cylindrical lens effect obtained by the acousto-optical deflecting element 1 can be corrected in accordance with the distance (d).
