<p>PURPOSE: To provide a light spot array projection device capable of performing batched high-density recording without sacrificing a space in spite of the use of a general-purpose light spot array. CONSTITUTION: This device is provided with projection optical systems 12a-12d comprising K (K>=2) light spot arrays 10a-10d forming light spot trains one- dimensionally arranged, respectively, K unit reducing optical means individually reducing the light beams from the respective light spot trains of the K light spot arrays 10a-10d, respectively, and at least (K-1) unit optical path converting elements bending the light beams from the respective light spot trains of at least (K-1) light spot arrays from among K light spot arrays at different angles, respectively, in a plane perpendicular to the array direction.</p> |
