Cover Mechanism for Automatic Sheet Type Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in setting appropriate image processing conditions for different types of sheets in image processing apparatuses, as they need to manually adjust settings for each type of sheet during every image processing operation.
Innovation Solution
An image processing apparatus with a cover mechanism that automatically sets image processing conditions based on the open or closed state of the cover, determining whether to read a card or a plain sheet, thereby eliminating the need for users to manually set conditions for each type of sheet.

Engineering Contradiction Analysis
1Manufacturing precision
If users manually set image processing conditions for each type of sheet, then appropriate image processing can be performed for different sheet types, but user operation becomes complicated and time-consuming
Solution Approach 1:
The system automatically detects the sheet type through the cover state and selects appropriate image processing conditions without user intervention. The cover state detection mechanism enables the system to self-determine whether to apply card reading conditions or plain sheet reading conditions, eliminating the need for manual setting while maintaining accurate image processing.
Solution Approach 2:
The cover state detection is performed in advance before image processing begins. By detecting the cover state beforehand, the system can pre-select the appropriate image processing conditions based on whether a card or plain sheet is being processed, ensuring accurate conditions are applied without requiring real-time user input.
2Adaptability or versatility
If the system provides multiple introducing parts for different sheet types, then versatility is improved, but device complexity increases
Solution Approach 1:
A single cover mechanism serves multiple functions by indicating different sheet types through its state (open/closed). The cover structure is not dedicated to a specific sheet type but rather provides a universal indication mechanism that works for both card and plain sheet processing, reducing the need for separate complex identification systems for each sheet type.
Solution Approach 2:
The cover state acts as an intermediary indicator between the user's intention (processing card or plain sheet) and the image processing system. Instead of directly complex sheet type detection, the cover state serves as a simple mediator that conveys the sheet type information to the control system, simplifying the overall device structure.

AI summary
An image processing apparatus includes: a conveyer configured to convey a sheet; a first introducing part configured to introduce a first-type sheet toward the conveyer; a second introducing part configured to introduce a second-type sheet different from the first-type sheet toward the conveyer; a cover configured to be displaced between an open state, in which the second introducing part is opened, and a closed state, in which the first introducing part is opened and the second introducing part is closed; an image processor configured to perform image processing according to a sheet conveyed by the conveyer; and a controller, wherein in a case where the cover is in the closed state, the controller performs a first setting process to set a first image processing condition corresponding to image processing according to the first-type sheet.
