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.
