Solution Overview

Problem

In print processing, mixed sheet sizes and orientations can result in characters being output in inverted states, requiring manual user intervention to adjust printer settings, which is impractical for automated or non-user-driven modes.

Innovation Solution

A character output device with a character direction specification unit and a character rotation determination unit that automatically specifies the drawing direction of characters for each page and determines if the page needs rotation based on the output medium's orientation, ensuring characters are output in a readable state without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual user intervention is used to adjust printer settings for mixed sheet sizes and orientations, then character orientation can be corrected, but the operation becomes complex and impractical for automated modes

Engineering Contradiction:
Improvecharacter orientation correctnessVSAvoiduser intervention requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The print processing system automatically detects mixed sheet sizes and orientations in the print data, determines the appropriate page rotation angles, and executes the rotation without requiring any user intervention. The system serves itself by autonomously resolving the character orientation issue that would otherwise require manual user adjustment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis of the print data to identify pages with mixed sheet sizes and orientations before actual printing occurs. By detecting these conditions in advance and pre-calculating the necessary rotation angles, the system prepares the correct orientation settings beforehand, ensuring characters are properly oriented without requiring user intervention during the printing process.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automated print processing is implemented without character rotation detection, then printing speed increases, but characters may be output in inverted states

Engineering Contradiction:
Improveprint processing speedVSAvoidcharacter readability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system replaces manual mechanical adjustment of printer settings with an automated information processing mechanism. The control unit analyzes print data, detects mixed sheet sizes and orientations, calculates rotation angles, and automatically adjusts the printing parameters through software control, eliminating the need for manual intervention while maintaining character readability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system incorporates a feedback mechanism where the control unit continuously monitors the print data for mixed sheet sizes and orientations, automatically adjusts page rotation settings based on this detection, and verifies the correctness of character orientation before printing. This closed-loop feedback ensures characters are always output in the correct readable state without compromising printing speed.

Inventive Principle:
Principle #23Feedback

3Reliability

If page rotation is automatically determined based on sheet size and orientation detection, then character orientation is corrected, but the processing complexity increases

Engineering Contradiction:
Improvecharacter orientation accuracyVSAvoidprocessing mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system changes the parameter being controlled from manual printer settings to automated page rotation angles. By detecting sheet sizes and orientations as input parameters and calculating the corresponding rotation angle as the output parameter, the system simplifies the processing mechanism while maintaining high accuracy in character orientation correction.

Inventive Principle:
Principle #35Parameter changes

AI summary

A character output device includes: a character direction specification unit that specifies a drawing direction of characters for each processing-target region of a processing-target page; a character rotation determination unit that determines as to whether the processing-target page rotates or not based on a relation between the specified drawing direction and a direction of an output medium; and an output unit that performs an output processing based on the determination by the character rotation determination unit.
