ABSTRACT:
A light beam recording device. A light beam irradiated from a light beam irradiating device is scanned onto an object to be illuminated, which is provided in a vicinity of a focal position, while being focussed by a scanning optical system. A converging member is disposed on an optical path between the light beam irradiating device and the scanning optical system, and converges a light beam which is incident on the converging member. An optical path changing device is disposed in a vicinity of a converging position of a light beam which is converged by the converging member, and changes an optical path of the light beam.
