Information Bearing Medium with Marked Unit Data Zones for Accurate Code Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information bearing media with concave-convex portions for game machines face mis-recognition issues due to high moving speeds, as multiple convex portions can be mistaken for a single convex portion when sequentially arranged, leading to inaccurate identification of coded information.
Innovation Solution
The introduction of an information bearing medium with a media substrate featuring unit data zones arranged in a two-dimensional array, where each unit data zone string has a distinct mark pattern in one direction, and the use of a guided portion to facilitate accurate detection and processing of digital codes, reducing mis-recognition by ensuring clear differentiation between adjacent convex portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple convex portions are sequentially arranged to increase information capacity, then the amount of information provided increases, but the border between adjacent convex portions becomes indistinct leading to mis-recognition
Solution Approach 1:
The information bearing medium is divided into multiple unit data zones arranged in a two-dimensional array, with each zone containing a convex portion. This segmentation allows multiple convex portions to be spatially separated and independently detected, preventing mis-recognition while maintaining high information capacity through the array structure.
Solution Approach 2:
The patent transitions from a one-dimensional sequential arrangement of convex portions to a two-dimensional array of unit data zones. This dimensional change provides clear spatial separation between adjacent convex portions in both horizontal and vertical directions, enabling accurate detection of borders between multiple convex portions while maximizing information density.
2Productivity
If the moving speed of the concave-convex portion relative to the switch is high, then processing efficiency increases, but mis-recognition of adjacent convex portions occurs
Solution Approach 1:
The patent pre-arranges convex portions in a fixed two-dimensional array pattern on the information bearing medium before insertion. This preliminary structuring allows the detection system to anticipate and accurately identify the position and border of each convex portion even at high moving speeds, maintaining detection reliability without sacrificing processing efficiency.
Data Source
AI summary
An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.
