IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18334607 titled 'IMAGE FORMING APPARATUS
Simplified Explanation
The abstract describes an image forming apparatus that includes a detachable unit with a rotator and a drive unit with a drive shaft coupling. The drive unit provides a force to the rotator via the drive shaft coupling, which engages with the driven shaft coupling on the rotator. The driven shaft coupling has spiral first and second receiving surfaces, while the drive side shaft coupling has a spiral first transmitting surface and a spiral second transmitting surface.
- The driven shaft coupling has spiral receiving surfaces, while the drive side shaft coupling has spiral transmitting surfaces.
- The first transmitting surface on the drive side shaft coupling provides a rotational force in a first direction to the driven shaft coupling.
- The second transmitting surface on the drive side shaft coupling provides a force in the opposite direction to the first direction to the driven shaft coupling when the drive shaft coupling rotates in the second direction.
- The second transmitting and receiving surfaces are rougher than the first transmitting and receiving surfaces.
Potential applications of this technology:
- Image forming apparatuses in various industries such as printing, photography, and graphic design.
- Any application that requires precise rotational force transmission.
Problems solved by this technology:
- Efficient and reliable transmission of rotational force between detachable units.
- Enhanced stability and accuracy in image forming processes.
Benefits of this technology:
- Improved performance and durability of image forming apparatuses.
- Simplified maintenance and replacement of detachable units.
- Increased efficiency and productivity in image forming processes.
Original Abstract Submitted
Disclosed is an image forming apparatus including a detachable unit having a rotator with a driven shaft coupling and a drive unit having a drive shaft coupling to engage with the driven shaft coupling and providing a force to the rotator via the drive shaft coupling. The driven shaft coupling includes spiral first and second receiving surfaces. The drive side shaft coupling includes a spiral first transmitting surface, which contacts the first receiving surface and provides a rotational force in a first rotational direction to the driven shaft coupling, and a spiral second transmitting surface, which contacts the second receiving surface and provides a force in the second rotational direction opposite to the first rotational direction to the driven shaft coupling when the drive shaft coupling rotates in the second rotating direction. The second transmitting and receiving surfaces are rougher than the first transmitting and receiving surfaces.
