Display Apparatus Scrolling Subregions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses require multiple operations to scroll through a large number of destination candidates, making it cumbersome for users to find and select a desired destination.
Innovation Solution
A display apparatus with a storage unit for destination data, a display unit showing a destination candidate display section and a scroll bar, and an operation unit allowing users to scroll through destination candidates by tapping specific subregions within the scroll operation regions, which are divided into multiple subregions for precise scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a button is used to scroll destination candidates by a predetermined amount, then the display unit can show multiple destination candidates, but the button needs to be operated many times to find a desired destination when a large number of candidates are registered
Solution Approach 1:
The scroll operation region is divided into multiple subregions (first subregion, second subregion, third subregion, fourth subregion). Each subregion corresponds to a different scroll amount when operated. This segmentation allows users to scroll through destination candidates more efficiently by selecting the appropriate subregion based on how far they need to navigate, reducing the number of operations required compared to fixed predetermined scrolling.
2Productivity
If the button scrolls by a predetermined amount, then the scrolling mechanism is simple, but it requires multiple operations to navigate through large numbers of destination candidates
Solution Approach 1:
The scroll operation region is segmented into multiple subregions that provide different scroll amounts. This allows the system to offer multiple scrolling speeds without requiring separate physical buttons or complex controls, maintaining relative simplicity while improving productivity.
Solution Approach 2:
The patent adds a spatial dimension to the scrolling control by dividing the scroll operation region into multiple subregions positioned at different locations. Instead of using multiple separate buttons, the solution uses the spatial arrangement of subregions within a single display area to provide varied scroll amounts, effectively using the display screen's two-dimensional space to control scrolling behavior.

AI summary
A multifunction peripheral includes a display unit configured to display a destination designation screen including a destination candidate display section for displaying a predetermined number of destination candidates among the plurality of destination candidates to be capable of being scrolled in the up-down direction and a scroll bar indicating a scroll state of the destination candidate display section, an operation unit configured to receive operation for pointing a position in the destination designation screen, and a control unit configured to specify, based on the operation, a destination out of the plurality of destination candidates. Scroll operation regions for scrolling the destination candidates are set in the destination designation screen. The scroll operation regions are divided into a plurality of subregions. When the operation unit receives the operation on any one of the subregions, the destination candidates displayed in the destination candidate display section change according to the operated subregion.
