<p>An optical printer of the scanning type comprising a light emitting element drivable in accordance with printing data for emitting light, an optical system for passing the light therethrough to focus the light on a photosensitive member, a mirror movably interposed between the optical system and the photosensitive member for deflecting the beam from the optical system to cause the beam to scan the photosensitive member at a high speed, and an operation assembly for supporting the mirror pivotally movably so as to direct its reflecting surface toward the light emitting element, and for subjecting the mirror to a simple harmonic motion within a specified range of angles.</p> |
