Rotating Display Preview Enlargement for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses struggle to efficiently display and enlarge previews of images in both landscape and portrait orientations, leading to difficulties in recognizing character images and checking detailed previews.
Innovation Solution
An information processing apparatus, including an operation device, a display device with a rotation mechanism, a detection sensor, and a control device, which allows the display device to rotate between landscape and portrait orientations and dynamically adjusts the preview display area to ensure optimal viewing regardless of the device orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display device displays a preview in landscape orientation, then the preview area is wide, but vertically long previews cannot be displayed efficiently
Solution Approach 1:
The display device enables dynamic rotation between landscape and portrait orientations, allowing the preview display area to adapt its shape according to the content being displayed. This resolves the contradiction by making the display configuration flexible rather than fixed, so that vertically long previews can be displayed efficiently in portrait mode while wide previews use landscape mode.
Solution Approach 2:
The invention introduces orientation as an additional dimension for preview display, transitioning from a single landscape orientation to multiple orientations (landscape and portrait). This allows the system to optimize the preview display area configuration based on the aspect ratio and content requirements, resolving the limitation of fixed landscape display for vertical content.
2Adaptability or versatility
If the display device is fixed in landscape orientation, then the device structure is simple, but previews cannot be efficiently displayed in portrait orientation
Solution Approach 1:
The display device incorporates a rotation mechanism that enables dynamic switching between landscape and portrait orientations. This dynamic capability provides adaptability for different preview display needs while maintaining a relatively simple structural implementation through basic rotational joints and detection sensors.
Solution Approach 2:
The display device is designed with multi-functional capability to operate efficiently in both landscape and portrait orientations. This universality allows the same device structure to serve multiple display scenarios, whether for wide previews in landscape mode or vertically long previews in portrait mode, without requiring separate dedicated structures for each orientation.
3Area of moving object
If the preview is enlarged in landscape orientation, then the preview area increases, but the preview may not fit properly when switching to portrait orientation
Solution Approach 1:
The system dynamically adjusts the preview display configuration based on the detected orientation. When the display device rotates between landscape and portrait modes, the controller automatically recalculates and repositions the preview within the display area, ensuring consistent and reliable display regardless of orientation changes.
Solution Approach 2:
The display device incorporates detection sensors that provide feedback on the current orientation state to the controller. This feedback mechanism enables the system to automatically adapt the preview display parameters (position, size, orientation) to match the current device orientation, maintaining display consistency and preventing distortion or improper fitting during orientation transitions.

AI summary
An image forming apparatus includes: a rotation mechanism capable of rotating a rectangular display device between a landscape orientation with longer sides being top and bottom and a portrait orientation with shorter sides being top and bottom; a detection sensor that detects switching of the display device between the landscape orientation and the portrait orientation; and a controller that, upon detection of switching of the display device from the landscape orientation to the portrait orientation by the detection sensor, enlarges a preview display area and allows a preview to be displayed in a size enlarged to fit the enlarged preview display area and displayed to make top and bottom edges of the preview parallel to the shorter sides of the display device.
