CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17963245 titled 'CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

Simplified Explanation

The abstract describes a cartridge for an electrophotographic image forming apparatus that includes a rotatable driving coupling member and a rotatable driven coupling member. The cartridge is demountable in a direction perpendicular to the rotational axis of the driving coupling member. The driven coupling member is slidable in a predetermined direction parallel to the rotational axis of the receiving coupling member. The driving side abutment and the driven side abutment are inclined so that the driven coupling member can retract away from the driving coupling member when a force is received from the driving side abutment.

  • The cartridge is designed to be easily removed from the main assembly of the image forming apparatus.
  • The driven coupling member can slide in a specific direction, allowing for flexibility in the coupling mechanism.
  • The inclined abutments enable the driven coupling member to retract when a force is applied, providing a disengagement mechanism.
  • The distance between the rotational axis of the driven coupling member and the abutment of the receiving abutment is limited, ensuring proper alignment and engagement between the coupling members.

Potential Applications

  • This technology can be applied in electrophotographic image forming apparatus, such as laser printers, copiers, and multifunction devices.
  • It can be used in various industries that require image printing or copying, including offices, schools, and commercial printing companies.

Problems Solved

  • The cartridge allows for easy removal and replacement of components in the image forming apparatus, simplifying maintenance and reducing downtime.
  • The sliding and retracting mechanism provides flexibility and disengagement options, preventing damage to the coupling members in case of excessive force or misalignment.
  • The limited distance between the rotational axis and the abutment ensures proper alignment and engagement, improving the overall performance and reliability of the apparatus.

Benefits

  • Easy removal and replacement of the cartridge components simplify maintenance and reduce downtime.
  • The sliding and retracting mechanism provides flexibility and prevents damage to the coupling members, increasing the lifespan of the apparatus.
  • Proper alignment and engagement improve the performance and reliability of the image forming apparatus, resulting in high-quality prints and copies.


Original Abstract Submitted

A cartridge for a main assembly of an electrophotographic image forming apparatus, wherein the main assembly includes a rotatable driving coupling member including a driving force transmitting portion for transmitting a driving force and a driving side abutment, wherein the cartridge is demountable in a direction substantially perpendicular to a rotational axis of the driving coupling member, includes a rotatable driven coupling member including a driving force receiving portion for receiving the driving force, and a driven side abutment to be abutted by the driving side abutment, the driven coupling member being slidable in a predetermined direction which is substantially parallel with a rotational axis of the receiving coupling member; wherein at least one of the driving side abutment and the driven side abutment is inclined so that the driven coupling member is retractable away from the driving coupling member in the predetermined direction by a force received by driven side abutment from the driving side abutment, and wherein a distance between the rotational axis of the driven coupling member and the abutment of the receiving abutment is not more than a distance between the rotational axis of the driven coupling member and the driving force receiving portion.
