PHOTOSENSITIVE MEMBER UNIT, CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17854573 titled 'PHOTOSENSITIVE MEMBER UNIT, CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes a detachable photosensitive member unit for an image forming apparatus. The unit includes helical gear portions that engage with corresponding gear portions on the main assembly of the apparatus. The helical gear portions have the same twisting direction but different helix angles. The unit can rotate while in meshing engagement with the main assembly gear portions.

  • The photosensitive member unit is detachable and can be easily mounted onto the main assembly of the image forming apparatus.
  • The unit includes helical gear portions that engage with corresponding gear portions on the main assembly, allowing for smooth rotation.
  • The helical gear portions have the same twisting direction, ensuring proper meshing engagement.
  • The helix angle of the second unit side helical gear portion is larger than that of the first unit side helical gear portion, providing improved performance.
  • The unit can rotate while in meshing engagement with the main assembly gear portions, allowing for efficient operation.

Potential Applications

  • This technology can be applied in various image forming apparatus, such as printers, copiers, and scanners.
  • It can be used in both personal and commercial settings where image reproduction is required.

Problems Solved

  • The detachable photosensitive member unit solves the problem of easily replacing or upgrading the photosensitive member in an image forming apparatus.
  • The helical gear portions ensure smooth and efficient rotation, reducing the risk of gear damage or malfunction.

Benefits

  • The detachable unit allows for easy maintenance and replacement of the photosensitive member, reducing downtime.
  • The helical gear design improves the performance and reliability of the image forming apparatus.
  • The ability to rotate while in meshing engagement enhances the efficiency of the apparatus.


Original Abstract Submitted

A photosensitive member unit detachably mountable to a main assembly of an image forming apparatus, the image forming apparatus including a first main assembly side helical gear portion and a second main assembly side helical gear portion which are coaxially rotatable, the photosensitive member unit includes a photosensitive member rotatable about a rotational axis thereof; a first unit side helical gear portion for meshing engagement with the first main assembly side helical gear portion; and a second unit side helical gear portion for meshing engagement with the second main assembly side helical gear portion, wherein a twisting direction of a tooth of the second unit side helical gear portion is the same as the twisting direction of a tooth of first unit side helical gear portion, wherein a helix angle of the tooth of the second unit side helical gear portion is larger than a helix angle of the tooth of the first unit side helical gear portion, and wherein the first unit side helical gear portion and the second unit side helical gear portion are rotatable in a state in which the first unit side helical gear portion is in meshing engagement with the first main assembly side helical gear portion, and the second unit side helical gear portion is in meshing engagement with the second main assembly side helical gear portion.
