IMAGE READING APPARATUS AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240267474 titled 'IMAGE READING APPARATUS AND IMAGE FORMING APPARATUS

The image reading apparatus described in the patent application includes a conveyance member, a transparent member, a background member, and a reading unit. The reading unit is positioned opposite to the background member in relation to the transparent member and consists of a light source and a reading sensor. The light source emits light towards a sheet, while the reading sensor captures the shadow and image of the sheet through the transparent member. The shadow of the sheet is projected onto the background member, with the light irradiating direction inclined downstream in the conveyance direction towards the downstream side.

The apparatus includes a conveyance member, transparent member, background member, and reading unit.
The reading unit comprises a light source and a reading sensor.
The light source emits light towards a sheet, while the reading sensor captures the shadow and image of the sheet.
The shadow of the sheet is projected onto the background member.
The background member has a planar shape that inclines towards the transparent member in the conveyance direction.

Potential Applications: - Document scanning and digitization - Image processing and analysis - Quality control in printing and manufacturing industries

Problems Solved: - Efficient reading and digitization of images - Accurate capturing of shadows and images on a sheet - Improved quality control processes

Benefits: - Enhanced image reading accuracy - Streamlined document scanning procedures - Increased efficiency in quality control tasks

Commercial Applications: Title: Advanced Image Reading Technology for Enhanced Document Scanning This technology can be utilized in office equipment such as scanners, printers, and copiers to improve image reading and document digitization processes. It can also find applications in industries requiring precise image analysis and quality control measures.

Questions about the technology: 1. How does the apparatus ensure accurate reading of shadows and images on a sheet? 2. What are the potential industrial applications of this image reading technology?

Original Abstract Submitted

an image reading apparatus includes a conveyance member, a transparent member, a background member, and a reading unit. the reading unit arranged on an opposite side to the background member with respect to the transparent member. the reading unit includes a light source and a reading sensor. the light source emits light toward a sheet. the reading sensor reads a shadow of a sheet and an image of the sheet through the transparent member. the shadow of the sheet is projected onto the background member. as viewed in a width direction perpendicular to a conveyance direction, an irradiating direction of the light inclines downstream in the conveyance direction toward a downstream side in the irradiating direction. the background member has a planar shape that is inclined to approach the transparent member from an upstream side toward a downstream side in the conveyance direction.
