Abstract
An optical printer of the scanning type includes a light emitting element which is drivable in accordance with printing data for emitting light. The printer also includes an optical system which passes the light through the system to focus the light on a photosensitive member. A mirror is movably interposed between the optical system and the photosensitive member to deflect the beam from the optical system, thereby causing the beam to scan the photosensitive member at a high speed. To realize the scanning process, an operation assembly supports the mirror to pivotally move the mirror so that the mirror's reflecting surfaces faces toward the light emitting element by subjecting the mirror to a simple harmonic motion within a specified range of angles.
