DRUM UNIT, CARTRIDGE AND COUPLING MEMBER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18656724 titled 'DRUM UNIT, CARTRIDGE AND COUPLING MEMBER
The abstract of the patent application describes a cartridge with a coupling positioned at the end of a photosensitive drum, featuring a movable projection within the coupling.
- The coupling includes a cylindrical main body positioned coaxially with the photosensitive drum and open to the outside of the cartridge.
- A projection within the cylindrical main body is movable between two positions, adjusting its distance from the rotational axis of the coupling.
- Part of the cylindrical main body is located outside the photosensitive drum, while another part is inside the drum.
- The projection is at least partially positioned inside the photosensitive drum.
Potential Applications: - This technology could be used in printers, copiers, and other imaging devices that utilize photosensitive drums. - It may improve the efficiency and reliability of cartridge replacement processes in imaging equipment.
Problems Solved: - The movable projection allows for precise alignment and connection between the cartridge and the imaging device. - It may prevent potential damage to the photosensitive drum during cartridge replacement.
Benefits: - Enhanced accuracy and stability in cartridge installation. - Reduced risk of errors or malfunctions in imaging equipment. - Improved overall performance and longevity of the device.
Commercial Applications: Title: Innovative Cartridge Coupling Technology for Imaging Devices This technology could be valuable for manufacturers of printers, copiers, and other imaging devices looking to enhance the user experience and reliability of their products.
Questions about the technology: 1. How does the movable projection in the coupling improve the cartridge replacement process? - The movable projection allows for precise alignment and connection between the cartridge and the imaging device, reducing the risk of errors or damage. 2. What are the potential benefits of using this technology in imaging equipment? - The technology can improve accuracy, stability, and overall performance of the device, leading to enhanced user experience and longevity.
Original Abstract Submitted
A cartridge includes a coupling positioned at an end of a photosensitive drum, with the coupling including (i) a cylindrical main body positioned coaxially with the photosensitive drum and open to outside of the cartridge and (ii) a projection positioned in the cylindrical main body. The projection is movable relative to the cylindrical main body between a first position and a second position such that an end of the projection is positioned closer to the rotational axis of the coupling when the projection is in the first position than when the projection is in the second position. A part of the cylindrical main body is positioned outside the photosensitive drum, and a part of the cylindrical main body is positioned inside of the photosensitive drum, and the projection is at least partially positioned inside of the photosensitive drum.
