Document Image Orientation Control for Consistent Sheet Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems do not account for the orientations of image data relative to the sheet discharge directions when printing, leading to misalignment of sheets and decreased usability.
Innovation Solution
An image processing apparatus that includes a control unit to align the orientations of image data relative to the sheet discharge directions, ensuring similar orientations for both sheets, and displays guidance for placing documents on the platen to prevent interference and improve usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reading unit reads documents larger than the document platen in two parts, then the reading capability is improved, but the sheet alignment precision deteriorates because the orientations of image data relative to sheet discharge directions are not considered
Solution Approach 1:
The control unit performs preliminary determination of the orientation of each piece of image data relative to the sheet discharge direction before the printing process. Based on this preliminary orientation information, the control unit automatically determines the placement orientation of documents on the document platen, ensuring that the orientation relationship between image data and sheet discharge direction is maintained throughout the entire document processing workflow.
2Ease of operation
If automatic document orientation determination is implemented, then the ease of operation is improved, but the device complexity increases due to additional control processes
Solution Approach 1:
The system performs self-service by automatically determining document placement orientations based on the orientation information of image data. The control unit autonomously processes the orientation determination without requiring user intervention or manual configuration, thereby improving ease of operation while managing device complexity through automated control logic.
3Ease of operation
If display guidance for document placement is provided, then the ease of operation is improved, but the loss of information increases due to additional screen content
Solution Approach 1:
The display control unit provides localized guidance information specifically related to document placement orientation on the document platen. This targeted information display approach ensures that users receive only the necessary orientation guidance without overwhelming them with unnecessary information, thereby improving ease of operation while minimizing information loss.

AI summary
An image processing apparatus includes a reading unit configured to execute a reading process for reading a document placed on a document platen, a printing unit configured to print image data obtained by the reading unit executing the reading process, and a control unit configured to execute a control process for performing control so that an orientation of first image data generated by the reading unit executing the reading process on the first document relative to a sheet discharge direction of a first sheet on which the first image data is printed by the printing unit, and an orientation of second image data generated by the reading unit executing the reading process on the second document relative to a sheet discharge direction of a second sheet on which the second image data is printed by the printing unit are similar orientations.
