HANDHELD PRINTING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17863496 titled 'HANDHELD PRINTING APPARATUS
Simplified Explanation
The patent application describes a manually scanned printing apparatus that can prevent deterioration in image quality. The apparatus includes a guide roller and a downstream position detection sensor, which can be adjusted relative to each other in a direction perpendicular to the printing surface of the print medium.
- The support portion of the guide roller and the support portion of the position detection sensor can be displaced relative to each other.
- The displacement is in a direction orthogonal to the printing surface of the print medium.
- The apparatus is manually scanned, meaning it requires human intervention for scanning.
- The purpose is to suppress any deterioration in the quality of the printed image.
Potential Applications
This technology can be applied in various printing devices, such as:
- Scanners
- Photocopiers
- Fax machines
- Handheld printers
Problems Solved
The technology addresses the following issues:
- Deterioration in image quality during manual scanning
- Misalignment between the guide roller and the position detection sensor
- Inaccurate detection of the print medium's position
Benefits
The benefits of this technology include:
- Improved image quality in manually scanned prints
- Enhanced accuracy in detecting the position of the print medium
- Prevention of misalignment between the guide roller and the position detection sensor
Original Abstract Submitted
Provided is a manually scannedprinting apparatus capable of suppressing deterioration in image quality. To provide this, a support portion of a guide roller and a support portion of a downstream position detection sensor are configured to be displaceable relative to each other in a direction substantially orthogonal to the printing surface of a print medium to be printed.
