Solution Overview

Problem

Conventional card readers require users to look away from the image display section to find the data read-out position, making the process inconvenient and prone to errors.

Innovation Solution

A data read-out device with an image display section that shows the location, timing, and orientation of the recording medium's position on the display surface, using an antenna positioned at the rear of the display panel to facilitate wireless data reading without the need for additional positioning components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If an image display section displays an image indicating the position of the read-out section, then the user can identify the position, but the user has to turn his/her gaze away from the image display section to find the read-out section

Engineering Contradiction:
Improveposition informationVSAvoiduser convenience
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent uses an image display section to display a visual copy or representation of the read-out section position. The image shows a graphic indicating where to place the recording medium, allowing users to understand the position requirement without physically searching for the read-out section. This resolves the contradiction by providing position information through visual copying rather than requiring direct visual inspection of the physical component.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The image display section acts as an intermediary between the system and the user. Instead of directly showing the physical read-out section, the system uses an intermediate visual representation that conveys the necessary position information. This intermediary provides the information in a form that doesn't require the user to shift attention between different physical locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If additional positioning components are added to indicate the read-out section position, then the position can be clearly indicated, but the device complexity and cost increase

Engineering Contradiction:
Improveposition informationVSAvoidcomponent quantity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The image display section serves multiple functions: it displays operational information, indicates the read-out section position, and provides user guidance. By making this existing component multi-functional, the patent avoids adding separate positioning indicators, thereby reducing device complexity while still providing clear position information.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the positioning indication function with the existing image display section. Instead of having separate components for displaying information and indicating position, the system combines these functions into a single integrated display that provides both operational status and positional guidance through visual graphics.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A card reader (data read-out device) causes an image display section to display an image that indicates a predetermined portion on a display surface of a display panel, as a portion where a non-contact IC card (recording medium) is to be close. An antenna for making communications with a non-contact IC card is arranged at a portion located at the rear side of the predetermined portion on a rear surface of the display panel. In a case where a user brings a non-contact IC card close to the predetermined portion on the display surface presented as an image, the card reader reads out data from a non-contact IC card wirelessly by using an antenna. A user can identify a portion where a recording medium is to be brought close without turning his/her gaze away from the display surface of the card reader. Therefore, it is possible to bring a recording medium close to a proper position so as to enable reading out data.
