PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240210874 titled 'PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS
Simplified Explanation:
This patent application describes a process cartridge with a photosensitive drum and a developing roller. The cartridge includes a coupling member that allows for the rotation of the developing roller.
Key Features and Innovation:
- The coupling member includes a driven portion, an intermediary portion, and a driving portion.
- The intermediary portion is movable relative to the driven portion and the driving portion, allowing for engagement while crossing the axis of the developing roller.
- The driving portion receives a driving force to rotate the developing roller.
Potential Applications: This technology can be used in various types of printers and copiers that utilize process cartridges with developing rollers.
Problems Solved: This innovation addresses the need for a reliable and efficient mechanism to rotate the developing roller in a process cartridge.
Benefits:
- Improved performance and reliability of printers and copiers.
- Simplified maintenance and replacement of process cartridges.
Commercial Applications: Commercial applications include the manufacturing and sale of process cartridges for printers and copiers in the office equipment industry.
Prior Art: Prior art related to this technology can be found in patents and research papers on process cartridges and developing roller mechanisms in printing devices.
Frequently Updated Research: Researchers may be conducting studies on the optimization of developing roller mechanisms in process cartridges for improved printing quality and efficiency.
Questions about Process Cartridges: 1. What are the key components of a process cartridge in a printer or copier? 2. How does the coupling member in this patent application improve the performance of the developing roller mechanism?
Original Abstract Submitted
a process cartridge comprises a photosensitive drum and a developing roller. a coupling member is provided adjacent to one axial end of the developing roller. the coupling member includes a driven portion, and an intermediary portion configured and positioned to engage with the driven portion. the intermediary portion is also configured to be movable relative to the driven portion in a direction crossing the axis of the developing roller while maintaining engagement with the driven portion. the coupling member further includes a driving portion configured and positioned to receive a driving force for rotating the developing roller. the driving portion is also configured to engage with the intermediary portion, and to be movable relative to the intermediary portion in a direction crossing the axis of the developing roller while maintaining engagement with the intermediary portion.
