Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers that use tape cassettes for label printing face issues with margins when input data is written horizontally, resulting in a smaller printing area and difficulty in seeing the printed part due to unnecessary margin inclusion.
Innovation Solution
A data processing device and printer system that includes an input unit, detection unit, partition region setting unit, valid region setting unit, longitudinal direction determination unit, and magnification determination unit, which partitions the input region, sets valid regions, determines the longitudinal direction, and adjusts the size of the input data to match the tape width, thereby excluding unnecessary margins during printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the entire input detection region including margin portions is set as the label printing data, then the data processing is simple, but the printing part becomes smaller and difficult to see due to unnecessary margins
Solution Approach 1:
The input detection region is divided into multiple partition regions, and the valid region is identified by detecting input positions within these partitions. This segmentation allows the system to distinguish between useful input data and unnecessary margin portions, thereby improving printing part visibility while maintaining reasonable processing complexity through automated region identification.
Solution Approach 2:
The patent extracts only the necessary input data from the input detection region by identifying the valid region based on detected input positions. The margin portions are excluded from the printing data, thereby eliminating unnecessary margins and improving the visibility and quality of the printing part.
2Manufacturing precision
If the input detection region is partitioned into multiple partition regions and valid regions are identified, then the printing part visibility is improved, but the data processing complexity increases
Solution Approach 1:
The system automatically identifies the valid region by detecting input positions within the partitioned regions. The detection unit and valid region setting unit work together to autonomously determine which partition regions contain useful input data, eliminating the need for manual configuration and reducing the practical complexity despite the partitioning mechanism.
3Productivity
If the drawing size is enlarged or reduced to conform to tape width, then the printing medium utilization is improved, but the input data must be transformed which increases processing complexity
Solution Approach 1:
The patent applies parameter changes by calculating a magnification value based on the relationship between the valid region dimensions and the tape width. The drawing is then scaled accordingly to match the tape width, optimizing printing medium utilization. This automated parameter adjustment handles the data transformation complexity through mathematical calculations rather than manual intervention.

AI summary
A data processing device includes an input unit including an input detection region, a detection unit, a partition region setting unit, a valid region setting unit, a longitudinal direction determination unit and a magnification determination unit. The detection unit detects input to the input detection region. The partition region setting unit partitions the input detection region into partition regions. The valid region setting unit sets, among said partitioned partition regions, a partition region in which input is detected as a valid region. The longitudinal direction determination unit determines a longitudinal direction of the valid region. The magnification determination unit determines a magnification for enlarging or reducing a size of a drawing corresponding to the input in the valid region, so that a width along a direction perpendicular to the longitudinal direction of the valid region conforms to a width along a transverse direction of a printing medium.
