IMAGE READING APPARATUS AND IMAGE FORMING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18056196 titled 'IMAGE READING APPARATUS AND IMAGE FORMING SYSTEM
Simplified Explanation
An image reading apparatus is described in this patent application. The apparatus includes various components such as conveyance rollers, transparent members, reading units, opposing rollers, and a driving unit.
- The first reading unit reads an image on the first surface of a sheet at a specific position using a transparent member.
- The first opposing roller is positioned opposite the first transparent member at the first reading position.
- The second reading unit reads an image on the second surface of the sheet at a different position using a second transparent member.
- The second opposing roller is positioned opposite the second transparent member at the second reading position.
- The second conveyance roller is located in a position where the trailing edge of the sheet passes through the first reading position while being conveyed.
- The driving unit controls the speed of the first opposing roller to be faster than the speed of the second conveyance roller.
Potential applications of this technology:
- Document scanning: The image reading apparatus can be used in scanners to read both sides of a document quickly and accurately.
- Photocopying: This technology can be incorporated into photocopiers to efficiently scan and reproduce double-sided documents.
- Fax machines: The image reading apparatus can be utilized in fax machines to transmit both sides of a document over a telephone line.
Problems solved by this technology:
- Efficient double-sided scanning: By using two reading units and transparent members, this apparatus enables simultaneous scanning of both sides of a sheet, saving time and effort.
- Accurate image capture: The opposing rollers ensure that the sheet remains flat and in the correct position during scanning, resulting in clear and accurate image capture.
Benefits of this technology:
- Time-saving: The simultaneous scanning of both sides of a sheet reduces the overall scanning time, increasing productivity.
- Improved image quality: The use of opposing rollers and transparent members ensures that the sheet remains flat and properly aligned, resulting in high-quality image capture.
- Versatility: This technology can be incorporated into various devices such as scanners, photocopiers, and fax machines, making it suitable for a wide range of applications.
Original Abstract Submitted
An image reading apparatus includes first and second first conveyance rollers, transparent members, reading units, and opposing rollers, and includes a driving unit. The first reading unit reads an image on a sheet first surface through the first transparent member at a first reading position. The first opposing roller is opposed to the first transparent member at the first reading position. The second reading unit reads an image on a sheet second surface through the second transparent member at a second reading position. The second opposing roller is opposed to the second transparent member at the second reading position. The second conveyance roller is arranged where a sheet trailing edge passes through the first reading position while the second conveyance roller conveys the sheet. The driving unit drives the first opposing roller so that a first opposing roller circumferential speed is faster than a second conveyance roller circumferential speed.
