Portable Terminal Mode Switching for Image Formers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it cumbersome to operate portable terminals to set communication modes for linking with image forming devices, as they need to switch between card emulation and peer-to-peer modes for logging in and data exchange, respectively.
Innovation Solution
A communication system that automatically sets the portable terminal to the appropriate mode based on the screen displayed on the image forming device, eliminating the need for users to manually select communication modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable terminal manually sets the communication mode, then the communication function can be performed, but the ease of operation deteriorates due to the need to switch between card emulation mode and peer-to-peer mode
Solution Approach 1:
The portable terminal automatically determines and switches between card emulation mode and peer-to-peer mode based on the communication mode information received from the image forming device, eliminating the need for manual user intervention in mode selection
Solution Approach 2:
The system uses feedback from the image forming device's communication mode information to automatically adjust the portable terminal's communication mode, creating a closed-loop control system that adapts to the required communication scenario
2Adaptability or versatility
If the portable terminal supports multiple communication modes, then the adaptability improves, but the device complexity increases due to mode switching mechanisms
Solution Approach 1:
The portable terminal dynamically switches between card emulation mode and peer-to-peer mode based on real-time communication mode information from the image forming device, allowing the system to adapt its behavior to different operational scenarios without requiring complex manual configuration

AI summary
The present invention improves user experience when a reader/writer (5) and a portable terminal (7) engage in near field communication by selecting any of two or more communication modes in order to link an image forming device (3) and the portable terminal (7) using near field communication. When a log-in screen is displayed on a display unit (403) of the image forming device (3), the reader/writer (5) and the portable terminal (7) are automatically set to a read communication mode.
