Image-Forming RFID Control With Mask-Pattern Writing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses require excessive time to detect multiple RFID tags on a print medium, leading to decreased user convenience.
Innovation Solution
The image forming apparatus selectively writes tag information to each wireless tag one by one, eliminating the need for individual detection, using a control device that includes a storage device, interface, and controller to manage the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the image forming apparatus detects individual RFID tags after the print medium is conveyed to the writing position, then the tag information can be written to the RFID tags, but the time required to detect the plurality of RFID tags increases as the number of RFID tags increases
Solution Approach 1:
The control device stores correspondence information that associates mask patterns with RFID tag positions before the actual tag writing operation. This pre-prepared mapping allows the system to directly write tag information to specific RFID tags without performing time-consuming individual detection during the writing process, thus reducing detection time while maintaining productivity
2Ease of operation
If the image forming apparatus detects individual RFID tags one by one, then the tag information can be written to each tag, but the user convenience decreases due to increased time requirement
Solution Approach 1:
The system pre-stores correspondence information mapping mask patterns to RFID tag positions before the writing operation. This allows the control device to directly access and write tag information to the correct RFID tags using the pre-established mapping, eliminating the need for time-consuming real-time detection and significantly reducing the overall tag writing time while maintaining ease of operation
Solution Approach 2:
Instead of detecting each RFID tag individually during the writing process, the system uses pre-stored correspondence information as a copy or representation of the RFID tag positions. This copied mapping data allows the system to proceed with tag writing without physically detecting each tag, thereby reducing time while preserving operational simplicity

AI summary
According to an embodiment, a control device repeatedly transmits tag information associated with a mask pattern, a selection command to select a wireless tag associated with the mask pattern among a plurality of wireless tags, and a write command to cause a wireless tag communication device to write the tag information associated with the mask pattern to the wireless tag communication device for each mask pattern stored in a storage device.
