Duplex Scanning Device for Certificate Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-function peripherals face challenges when scanning small hard documents like certificates, requiring manual handling and alignment, which is inconvenient and time-consuming, especially for users unfamiliar with the devices.
Innovation Solution
A scanning device with a duplex scan capability, comprising two parallel scanner modules, a control processor, and an output interface, that scans both sides of a data medium and converts analog data into digital data for efficient typesetting and outputting, allowing seamless integration with image forming apparatuses for convenient certificate copying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional multi-function peripheral is used to scan small hard documents, then the scanning function is available, but the user must manually turn over the document and decide reference position, which significantly deteriorates convenience in use
Solution Approach 1:
The device is segmented into two separate scanner modules (first scanner module and second scanner module) that operate independently but coordinate to scan both sides of the document simultaneously. This segmentation allows each module to handle one side of the document, eliminating the need for manual intervention.
Solution Approach 2:
The patent combines the functionality of two scanning operations (front side and reverse side) into a single coordinated process. The transport mechanism moves the document through both scanner modules in sequence, merging what would traditionally require two separate manual operations into one automated workflow.
2Reliability
If the flatbed scan function is executed on small hard documents, then scanning is possible, but the user needs to try many errors to find the correct placement position
Solution Approach 1:
The device performs self-alignment through its dual scanner module configuration and coordinated transport mechanism. The system automatically positions and scans both sides of the document without requiring the user to manually align or position the document, making the device self-sufficient in handling placement precision.
3Adaptability or versatility
If the user wants to copy both sides of the certificate on the same surface or different surfaces, then the copying function is available, but the user must manually place reproduced documents and shift placement position
Solution Approach 1:
The device dynamically adjusts its scanning and output process based on the selected copying mode. The control mechanism can switch between producing even-set data (for same-surface copying) and odd-set data (for different-surface copying), allowing the system to adapt to different user requirements without manual intervention.
4Productivity
If a simple certificate scanner is used, then front and reverse sides can be scanned, but the user must arrange scanned images on personal computer and transmit to copier, which is very time-consuming
Solution Approach 1:
The device is designed with universal output capabilities that can directly interface with image forming apparatuses. By providing standardized even-set and odd-set data formats, the device can work with multiple types of output devices (copiers, printers, etc.) without requiring intermediate processing on a personal computer, thus achieving multi-functionality and direct integration.
Data Source
AI summary
A scanning device comprises a scan assembly, a control processor and an output interface. The scan assembly comprises two scanner modules for scanning front and reverse sides of a data medium to obtain front side analog data and reverse side analog data. The control processor electrically connected to the scan assembly controls the scan assembly, and executes an analog-to-digital converting process to convert the front side analog data and the reverse side analog data into front side digital data and reverse side digital data. The output interface electrically connected to the control processor outputs even sets of digital data, comprising the front side digital data and the reverse side digital data, to an image forming apparatus, so that the image forming apparatus performs even-set data typesetting and outputting after the even sets of digital data are completely outputted. An image forming system using the scanning device is also disclosed.
