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

This abstract first appeared for US patent application 20240045355 titled 'OPTICAL SCANNING APPARATUS AND IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes an optical scanning apparatus that consists of a light source, a polygon mirror with multiple reflecting surfaces, and a casing to house these components. The polygon mirror can rotate around a rotary shaft. The casing has two spaces separated by a partition wall, with the second space located further from the rotary shaft than the partition wall. The second space overlaps with the first space in the axial direction.

  • The patent describes an optical scanning apparatus with a rotating polygon mirror.
  • The apparatus includes a light source and a casing to accommodate the mirror and light source.
  • The casing has two spaces, with the second space located further from the rotary shaft than the partition wall.
  • The second space overlaps with the first space in the axial direction.

Potential Applications:

  • Optical scanning systems in printers, scanners, or barcode readers.
  • Laser projection systems for displays or entertainment purposes.
  • Laser cutting or engraving machines.
  • Optical communication systems for data transmission.

Problems Solved:

  • Efficient and precise scanning of light beams.
  • Compact design for optical scanning devices.
  • Reduction of mechanical vibrations and noise during operation.
  • Improved reliability and longevity of the scanning apparatus.

Benefits:

  • High-speed and accurate scanning of light beams.
  • Compact and space-saving design for various applications.
  • Reduced mechanical vibrations and noise for improved user experience.
  • Enhanced reliability and durability of the scanning apparatus.


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.
