Paper Dust Receiver-Scraper Layout for Medium Conveying Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face difficulties in efficiently and cost-effectively discarding paper dust accumulated in the paper dust receiving recess.
Innovation Solution
A medium conveying apparatus with a cleaner, scraper, and receiver configuration that allows the receiver to be pulled out and attached in opposite directions, enabling the scraper to efficiently remove paper dust without additional mechanisms, thus simplifying operation and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a separate paper dust receiving recess is disposed below the scraping member, then paper dust can be received, but it becomes difficult to discard the accumulated paper dust
Solution Approach 1:
The paper dust receiving recess is segmented from the main apparatus body as a detachable receiver unit. This allows the receiver to be easily removed and discarded separately, solving the problem of difficult paper dust disposal while maintaining continuous paper dust reception capability.
Solution Approach 2:
The paper dust receiving recess is extracted as a separate detachable receiver that can be pulled out from the apparatus main body. This extraction enables easy removal and discarding of accumulated paper dust without affecting the main apparatus structure.
2Reliability
If additional mechanisms are added for scraper operation, then cleaning effectiveness improves, but apparatus size and cost increase
Solution Approach 1:
The scraper operation is merged with the receiver displacement movement. The scraper is provided to the receiver and automatically comes into contact with the cleaner when the receiver is displaced, eliminating the need for separate scraper actuation mechanisms while maintaining effective cleaning.
Solution Approach 2:
The receiver displacement mechanism serves dual purposes: it both removes the receiver for paper dust discarding and simultaneously operates the scraper to clean the cleaner surface. This multi-functionality reduces overall apparatus complexity while maintaining cleaning effectiveness.

Function Achieved in This Case
Facilitates easy disposal of paper dust, reduces apparatus size and cost, and enhances usability by integrating the scraper operation with the receiver's movement, ensuring thorough cleaning without additional mechanisms.
Implementation Method 1
a scraper configured to come into contact with the cleaner to scrape off paper dust from the cleaner
Implementation Method 2
a scraper configured to come into contact with the cleaner to scrape off paper dust from the cleaner

AI summary
A medium conveying apparatus includes a conveyer configured to convey a medium, a cleaner configured to clean the conveyer, a scraper configured to come into contact with the cleaner to scrape off paper dust from the cleaner, and a receiver disposed below the scraper and configured to receive the paper dust, wherein the receiver is pulled out from an apparatus main body by being displaced in a first direction and is attached to the apparatus main body by being displaced in a second direction opposite to the first direction, and the scraper is provided to the receiver and comes into contact with the cleaner to scrape off the paper dust from the cleaner when the receiver is displaced in at least one of the first direction and the second direction.
