OPTICAL SCANNING APPARATUS AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18359102 titled 'OPTICAL SCANNING APPARATUS AND IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes an optical scanning apparatus that includes a light source, a polygon mirror, and a casing. The polygon mirror has multiple reflecting surfaces and can rotate around a rotary shaft. The casing accommodates the light source and the polygon mirror and has two separate spaces, with a partition wall between them. The second space is further from the rotary shaft than the partition wall and overlaps with the first space in the axial direction.

  • The patent describes an optical scanning apparatus with a rotating polygon mirror.
  • The casing of the apparatus has two separate spaces, accommodating the mirror and the light source.
  • A partition wall separates the two spaces.
  • The second space is further from the rotary shaft than the partition wall.
  • The second space overlaps with the first space in the axial direction.

Potential applications of this technology:

  • Optical scanning systems in laser printers and copiers.
  • Barcode scanners and document scanners.
  • Laser projection systems for displays and presentations.
  • 3D scanning and imaging devices.

Problems solved by this technology:

  • Enables precise and efficient scanning of light beams.
  • Provides a compact and integrated design for optical scanning systems.
  • Reduces the complexity and cost of optical scanning apparatus.

Benefits of this technology:

  • Improved scanning accuracy and speed.
  • Compact and space-saving design.
  • Cost-effective manufacturing and assembly.
  • Versatile applications in various industries.


Original Abstract Submitted

An optical scanning apparatus includes a light source, a polygon mirror including a plurality of reflecting surfaces configured to reflect light emitted from the light source, the polygon mirror being configured to be rotated around a rotary shaft, and a casing configured to accommodate the light source and the polygon mirror. The casing defines a first space that accommodates the polygon mirror and a second space that is different from the first space, the casing including a partition wall disposed between the first space and the second space. The second space is disposed further from the rotary shaft than the partition wall in a radial direction orthogonal to an axial direction of the rotary shaft, and is disposed such that the second space overlaps with the first space in the axial direction.
