Roll Paper Printer Paper Guide with Movable Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll paper printers face the challenge of preventing cut and discharged sheets of paper from falling from the sheet discharge guide, leading to potential misalignment and operational inefficiencies.
Innovation Solution
The information terminal device incorporates a roll paper printer with a paper guide that includes a first guide for the first surface of the paper, a roller for guiding the second surface, and a support portion to movably support the roller's shaft, ensuring stable paper discharge through an issue port.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple sheet discharge guide is used, then the device complexity is reduced, but the paper sheets may fall from the guide causing operational inefficiencies
Solution Approach 1:
The patent introduces a roller component that rotates in a direction perpendicular to the paper transport direction, adding a rotational dimension to the paper guidance system. This rotational movement allows the roller to actively engage with and control the discharged paper sheets, preventing them from falling off the guide while maintaining a relatively simple overall structure.
Solution Approach 2:
The roller is designed to be rotatable by the weight and movement of the paper sheets themselves, without requiring additional motors or power sources. The paper sheets automatically drive the roller's rotation as they pass through, creating a self-powered guidance mechanism that maintains reliability without increasing device complexity.
2Device complexity
If a fixed roller support is used, then the structure is simplified, but the paper transport smoothness and alignment are compromised
Solution Approach 1:
The patent employs a movable support structure for the roller that can adjust its position in response to paper sheet characteristics. The support includes a movable arm or mounting mechanism that allows the roller to shift laterally or vertically, enabling smooth adaptation to variations in paper thickness, width, and stiffness, thereby maintaining easy paper transport without requiring a complex fixed support system.
Solution Approach 2:
The movable support structure allows dynamic adjustment of the roller's position parameters (such as distance from the guide surface or angular orientation) based on the paper sheet properties. This parameter adjustment capability enables the system to optimize paper transport smoothness for different paper types while keeping the overall support structure relatively simple.

AI summary
An information terminal device includes a roll paper printer that pulls out paper from paper roll, performs printing, and cuts the paper, a paper guide that guides the paper, and an issue port through which the paper is discharged, wherein the paper guide includes a first guide for guiding a first surface of the paper, a roller for guiding a second surface of the paper being a surface opposite to the first surface at a position facing the first guide, and a support portion permitted to movably support a shaft of the roller.
