Image Reading Apparatus Automatic Conveyance Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image reading apparatuses face inefficiencies in operability when successively reading multiple media, particularly due to time lags between medium feedings, which hinder productivity and user experience.
Innovation Solution
The apparatus includes an operating unit for issuing read-operation instructions, a conveying unit for medium transport, a display unit for state indication, and a medium detecting unit that initiates conveyance based on user input and detection, allowing for automatic start of reading operations on subsequent media once the previous one is processed, thereby reducing time lag and improving operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the conveying unit waits for manual confirmation before starting conveyance of subsequent media, then the reading operation can be completed accurately, but the time lag between media readings increases
Solution Approach 1:
The display unit provides preliminary information to the user about the completion status of reading operations and the readiness state of the conveying unit. This allows users to anticipate when subsequent media can be inserted, eliminating the need to wait for manual confirmation and reducing time lag between consecutive reading operations.
Solution Approach 2:
The system implements feedback through the display unit, which continuously informs users about the current state of the reading apparatus, including whether the previous medium has been fully processed and whether the conveying unit is ready for the next medium. This feedback mechanism enables users to time their media insertion optimally, reducing idle time while maintaining reading accuracy.
2Productivity
If the conveying unit automatically starts conveyance upon detection of subsequent media, then productivity is improved, but the risk of reading errors increases
Solution Approach 1:
The display unit provides real-time feedback about the system state, including whether the previous reading operation is complete and whether the conveying unit is ready to accept new media. This feedback loop ensures that automatic conveyance only occurs when appropriate, maintaining reading accuracy while enabling high productivity through automated operation.
3Measurement precision
If the system requires manual confirmation for each media conveyance, then reading accuracy is maintained, but operability and user convenience deteriorate
Solution Approach 1:
The system provides self-service through the display unit, which automatically tracks and communicates the reading status and conveying readiness to the user. This eliminates the need for users to manually confirm each step, improving ease of operation while maintaining accuracy through the automated status tracking and feedback mechanism.

AI summary
An image reading apparatus includes an operating unit that issues a starting instruction to start reading a medium which is a read-target medium, according to a user's operation, a conveying unit that conveys the medium, a display unit that displays states of the medium conveyed, a reading unit that reads the medium, and a medium detecting unit that detects the medium. The display unit displays contents indicating that the reading operation is possible when the reading operation of the medium is completed and the medium detecting unit does not detect the medium. The conveying unit starts conveyance of the medium in response to the read-operation starting instruction, when the read-target medium is a first medium in a set of media, and when the medium detecting unit detects the first medium, and the conveying unit starts conveyance of the medium, when the read-target medium is a second or later medium in the set of media, after the medium detecting unit detects the second or later medium.
