SHEET CONVEYANCE APPARATUS AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18362711 titled 'SHEET CONVEYANCE APPARATUS AND IMAGE FORMING APPARATUS
Simplified Explanation
The patent application describes a sheet conveyance apparatus with a roller pair, roller holder, and guiding portion.
- Roller pair consists of first and second rollers that can apply a predetermined force in a first state and reduce it in a second state.
- Roller holder has guided portions for the rollers to move in, allowing for different states of force application.
- Guiding portion includes guides for the guided portions, with the first guide inclined relative to the second guide.
- The angles formed by the straight line passing through the rotational centers of the rollers and the guiding directions differ based on the state of the rollers.
- Potential Applications
- Printing industry for precise sheet conveyance
- Packaging industry for accurate material handling
- Problems Solved
- Inconsistent force application on sheets
- Misalignment of rollers causing sheet jams
- Benefits
- Improved sheet conveyance accuracy
- Reduced risk of sheet damage
- Enhanced overall efficiency in material handling operations
Original Abstract Submitted
A sheet conveyance apparatus includes a roller pair having first and second rollers, a roller holder having first and second guided portions, and a guiding portion having first and second guides. The first and second rollers can take a first state where the first roller contacts the second roller with a predetermined force and take a second state where the predetermined force is reduced. A first direction in which the first guide guides the first guided portion is inclined relative to a second direction in which the second guide guides the second guided portion. When viewed in a rotational axis direction of the first roller with the first and second rollers in the first state, an angle formed by a straight line passing through rotational centers of the first and second rollers and the first direction is smaller than an angle formed by the straight line and the second direction.
