PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18661881 titled 'PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS
Simplified Explanation: The patent application describes a process cartridge with a frame, a photosensitive drum, a projection, and a gear, all designed to work together in a printing or copying machine.
- The frame of the process cartridge has a side surface where the photosensitive drum is supported and can rotate.
- A projection is positioned coaxial with the photosensitive drum, projecting from the side surface of the frame.
- A gear is also positioned at the side of the process cartridge, with some teeth exposed outside the cartridge.
Key Features and Innovation:
- Frame supporting a rotatable photosensitive drum.
- Projection coaxial with the drum, projecting from the frame.
- Gear with exposed teeth outside the cartridge.
Potential Applications: This technology can be used in printers, copiers, and other imaging devices that require a photosensitive drum for image formation.
Problems Solved: This technology provides a compact and efficient way to support and rotate a photosensitive drum in a process cartridge.
Benefits:
- Improved image quality.
- Enhanced durability and longevity of the process cartridge.
- Simplified maintenance and replacement of components.
Commercial Applications: This technology could be applied in the manufacturing of printers, copiers, and multifunction devices for both home and office use.
Prior Art: Readers interested in prior art related to this technology could explore patents and research papers on photosensitive drum assemblies in printing and imaging devices.
Frequently Updated Research: Researchers may find updated studies on the efficiency and performance of photosensitive drum technologies in printing applications.
Questions about Process Cartridge Technology: 1. What are the potential environmental impacts of using this technology in printing devices? 2. How does the design of the photosensitive drum affect the overall printing speed and quality?
Original Abstract Submitted
A process cartridge includes a frame having a side surface at a side of the process cartridge. A photosensitive drum is supported by the frame, the photosensitive drum being rotatable about an axis thereof, the photosensitive drum including a first end positioned at the side of the process cartridge and a second end opposite to the first end in a direction of the axis of the photosensitive drum. A projection is positioned coaxial with the photosensitive drum and at the side of the process cartridge, with the projection projecting from the side surface of the frame in the axial direction of the photosensitive drum with at least a tip of the projection being exposed to outside of the process cartridge. A gear is positioned at the side of the process cartridge, with the gear being rotatable about an axis thereof, the gear having a plurality of teeth, with at least some of the teeth being exposed teeth that are uncovered by the frame and exposed to outside of the process cartridge, and with a tip of at least one of the exposed teeth facing the axis of the photosensitive drum.
