Image Processing Apparatus for Saddle-Stitched Document Duplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for copying saddle-stitched documents are cumbersome and fail to accurately replicate the original document's binding structure, leading to issues with page order and continuity in the copied brochures.
Innovation Solution
An image processing apparatus that reads a document, divides image data into page-specific data, and assigns identifiers based on the document's page order, allowing for precise determination of the binding portion and page arrangement, enabling accurate reproduction of the document's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the document is copied page by page using conventional methods, then the copied pages can be assembled into a brochure, but the operation becomes extremely troublesome and time-consuming for users
Solution Approach 1:
The invention segments the copying process into two distinct modes: single-sided copying mode and double-sided copying mode. The controller automatically switches between these modes based on detection of the binding portion, allowing users to copy entire documents efficiently without manual page-by-page intervention while maintaining the ability to handle different copying requirements.
Solution Approach 2:
The system performs preliminary detection of the binding portion before the actual copying process begins. By identifying the binding portion in advance, the controller can pre-determine the appropriate copying mode and page arrangement, eliminating the need for users to manually configure settings for each page and streamlining the overall copying operation.
2Productivity
If single-sided copying is performed to reduce copying time, then the copy process is faster, but the copied papers become thicker than the original document
Solution Approach 1:
The copying system dynamically adjusts between single-sided and double-sided copying modes based on real-time detection of the binding portion. This dynamic adaptation allows the system to maintain thickness accuracy comparable to the original document when appropriate, while still achieving faster copying speeds by utilizing double-sided copying when the document structure permits.
3Device complexity
If the binding portion position is not determined, then the copying process can proceed without additional detection steps, but the document cannot be properly distinguished between first halves and latter halves, making it difficult to obtain accurate duplicates
Solution Approach 1:
The system employs self-service detection mechanisms where the copying apparatus automatically detects and identifies the binding portion position during the copying process. This self-detection capability eliminates the need for manual intervention or complex external detection equipment, maintaining simplicity while achieving accurate binding portion position determination for proper document duplication.
4Ease of operation
If two pages of a document are copied on one face of one paper without folding, then the copying operation is simplified, but the brochure lacks continuity in contents and has extremely inferior usability
Solution Approach 1:
The invention segments the copied content into appropriate page units that maintain logical continuity. By detecting the binding portion and understanding the document structure, the system divides the copied material into discrete pages that can be properly folded and bound, preserving content continuity while still simplifying the copying operation through automated processing.

AI summary
Disclosed is an image processing apparatus including a reading section to read a document and to obtain image data, the document including a plurality of sheets and having a binding portion; a storage section to store the image data; an operating section to accept an operating instruction to designate a position of the binding portion of the document, to designate a page order on one side of the binding portion of the document, and to designate one face out of faces of the sheets, from which a reading operation is started; and a controller, in accordance with the designation, to determine an image area corresponding to one page of the document, to divide the image data into pieces of page image data based on the image area, and to respectively give identifiers to the pieces of the divided page image data following a page order of the document.
