Rotatable Document Holder Display for Image Reading Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panels in image reading apparatuses limit the amount of information that can be displayed and input due to size constraints, requiring users to perform complex operations by switching display content multiple times, and increasing the size of the apparatus to accommodate larger panels is not feasible.
Innovation Solution
An image reading apparatus with a dual display system, where a first display unit is used for primary operations and a second, larger display unit on a rotatable document holder surface is activated based on the document's position, allowing more information to be displayed without increasing the apparatus' size, and a control unit manages the switching between the two displays based on user input and document position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the touch panel size is increased to display more information, then the amount of information that can be displayed increases, but the size of the image reading apparatus increases
Solution Approach 1:
The display system is divided into two separate display units: a first display unit integrated into the touch panel and a second display unit provided on the document holder. This segmentation allows each display unit to serve specific functions independently, enabling more information to be displayed across both units without requiring a single large touch panel that would increase the apparatus size.
Solution Approach 2:
The second display unit is provided on the document holder which can be rotated to different positions. When the document holder is rotated to a predetermined position, the second display unit becomes the active display area. This spatial reconfiguration allows the system to utilize the document holder surface as an additional display dimension without expanding the footprint of the main apparatus.
2Adaptability or versatility
If a larger touch panel is used to display more setting items, then the amount of information that can be input increases, but the space required for the touch panel increases
Solution Approach 1:
The document holder serves multiple functions: it holds the document for scanning and simultaneously acts as a carrier for the second display unit. This multi-functionality allows the system to provide an additional display area without adding separate dedicated space, thereby increasing the number of setting items that can be displayed and input without expanding the apparatus footprint.
Solution Approach 2:
The document holder is rotatable and can be positioned at different angles. The system dynamically switches between the first display unit and the second display unit based on the position of the document holder. This dynamic configuration allows the interface to adapt to different user needs, providing more setting items when the document holder is in the predetermined position while maintaining a compact apparatus design.
3Ease of operation
If the touch panel size is increased to reduce the need for switching display content, then user operation complexity decreases, but the overall apparatus size increases
Solution Approach 1:
By dividing the display functionality into two separate display units, the system can present more information simultaneously across both displays without requiring a single large touch panel. This reduces the need for users to switch between multiple display screens, simplifying operations while maintaining a compact apparatus size.

AI summary
Disclosed is an image reading apparatus which reads a document placed on a reading unit including a display input unit including a first display unit which displays information and an input unit to accept an input operation with respect to the first display unit; a document holder which sandwiches the document with the reading unit, a support which supports the document holder so as to rotate so that a facing state of the document holder with respect to the reading unit is switchable and a second display unit which includes a surface of the document holder which faces the reading unit and the second display unit carries out a display in the surface.
