  • Patent number: 4841311
    Abstract: A laser printer, wherein a laser beam emitting element is positioned close to a photosensitive element, employs a solid state deflective element for deflecting the laser beam. A laser beam optical path runs through a space between the laser beam emitting element and a reflective element, from which the optical path turns back to the photosensitive element beyond the laser beam emitting element. Thus, the laser beam can be efficiently deflected within a rather small capacity so that the printer can be small-sized. Additionally, since the printer has no mechanical moving parts, it is light-weight, efficient in operation, and free from mechanical adjustment requirements.
