Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multifeed detection systems in image reading apparatuses require users to perform cumbersome operations to set up multifeed disable conditions, such as measuring and inputting dimensions and positions, which is inefficient and inconvenient.
Innovation Solution
A multifeed processing apparatus with a control unit and storage unit that measures and determines multifeed detection patterns, allowing the system to automatically disable multifeed detection when specific patterns are recognized, enabling continuous image reading operations without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multifeed detection systems are used with manual setup, then multifeed detection accuracy is improved, but user operation complexity increases
Solution Approach 1:
The system automatically detects and measures multifeed patterns without requiring user intervention. The measuring unit autonomously identifies overlap positions and lengths, and the control unit automatically disables multifeed detection when patterns match stored disable patterns, eliminating manual setup operations while maintaining detection accuracy
Solution Approach 2:
The system pre-stores multiple multifeed disable patterns in the storage unit before actual reading operations begin. These patterns include various overlap positions and lengths that are likely to occur, allowing the system to quickly compare and disable detection without real-time manual configuration
2Measurement precision
If manual measurement and input of disable conditions is required, then detection precision is improved, but time consumption increases
Solution Approach 1:
The manual mechanical process of measuring and inputting dimensions is replaced by an automated optical measurement system. The measuring unit uses the image reading mechanism to automatically detect and measure overlap positions and lengths from captured images, eliminating the need for manual measurement tools and input operations
Solution Approach 2:
The system introduces an automatic measuring unit as an intermediary between the multifeed detection mechanism and the control unit. This measuring unit captures images, processes them to extract overlap information, and provides precise measurements to the control unit without requiring user involvement
3Productivity
If automatic multifeed disable pattern recognition is implemented, then operational efficiency is improved, but device complexity increases
Solution Approach 1:
The image reading mechanism serves multiple functions: it captures images for document scanning and simultaneously provides measurement data for multifeed pattern detection. The control unit performs both normal reading control and pattern matching operations. This multi-functionality reduces the need for separate dedicated components, managing complexity while enabling automatic operation

AI summary
A multifeed processing apparatus includes a control unit and a storage unit and is connected to a multifeed detecting mechanism and an image reading mechanism. The control unit includes (i) a measuring unit that measures a multifeed detection pattern from any one or both of an output of the multifeed detecting mechanism and an image of a medium read by the image reading mechanism, (ii) a determining unit that determines whether the measured multifeed detection pattern is included in a multifeed disable pattern stored in the storage unit, (iii) a reading control unit that regards a multifeed detection performed by the multifeed detecting mechanism as invalid, and causes the image reading mechanism to continue a reading operation, and (iv) a storage control unit that stores the measured multifeed detection pattern as the multifeed disable pattern in the storage unit.
