Display Screen Preview Image Actual Size Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses lack the ability to display preview images in actual size on a display screen that is proportional to the maximum size of the recording medium, making it difficult to ensure proper orientation and size verification before printing.
Innovation Solution
An image forming apparatus with a display screen that has dimensions equal to or greater than the longest side of the maximum size recording medium, allowing for actual-size preview display regardless of orientation, coupled with an image forming unit that can handle various sizes like A4, A3, and B3 formats, and an optional top board for space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display screen size is increased to show preview images in actual size, then the verification accuracy is improved, but the device depth increases
Solution Approach 1:
The patent transitions from displaying preview images in reduced scale to displaying them in actual size by utilizing a large-sized display screen. This dimensional change in display capability allows the preview image to be shown at 100% scale, enabling accurate verification of image orientation and content without requiring additional depth in the device structure.
2Adaptability or versatility
If the display screen is made large to accommodate maximum size recording medium dimensions, then the preview display capability is improved, but the overall device size increases
Solution Approach 1:
The patent applies local quality by providing a large display screen specifically for preview image display purposes, while the rest of the device maintains a compact form factor. The large display screen is positioned at the front surface, allowing the device to accommodate maximum size recording medium dimensions (such as A3 or B3 format) without requiring the entire device volume to increase proportionally.
3Measurement precision
If the display screen dimensions match the maximum recording medium size, then the orientation verification is improved, but the ease of operation is reduced
Solution Approach 1:
The patent enables preliminary verification of image orientation and content by displaying the preview image in actual size on the large display screen before the copying or printing process begins. Users can check whether the image is correctly oriented and contains all necessary content, and make adjustments if needed, thereby preventing errors in the final output.

AI summary
An image forming apparatus includes a display and an image forming unit. The display includes a display screen to display a preview image before an image is formed on a recording medium. The image forming unit forms, on the recording medium, an image corresponding to the preview image displayed on the display screen. Each of a vertical length and a horizontal length of the display screen is equal to or greater than a length of a long side of a maximum size recording medium on which an image is to be formed by the image forming unit.
