Document Feeder Notifier System for Operator Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators have difficulty visually confirming the presence of documents in a document feeder due to the placement of notification lamps away from the document placement section, leading to potential overlooking of documents that may fall.
Innovation Solution
A notifier system with light-emitting displays on the cover of the document feeder, featuring elongated first and second side surfaces and a recess, guides the operator's line of sight to the document placement section, improving visibility and understanding of notification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the notification lamp is disposed on the operation panel, then the notification lamp can be positioned away from the document placement section, but the operator may overlook the lighting of the notification lamp and it is difficult to understand the intent of the information notified
Solution Approach 1:
The notification lamp is moved from the operation panel to the cover of the document feeder, changing its spatial dimension and position. This allows the notification to be displayed closer to the document placement section, guiding the operator's line of sight directly to the relevant area and improving both visibility and understanding of the notification intent.
2Device complexity
If the document placement section is disposed at the rear of the operation panel, then the document feeder structure is compact, but the document is somewhat difficult for the operator to see
Solution Approach 1:
The cover serves as an intermediary element that bridges the operation panel and the document placement section. By placing the notification lamp on the cover, the system creates a visual connection between the notification and the document area, guiding the operator's attention to the document placement section without requiring structural changes that would compromise compactness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The notifier system effectively directs the operator's attention to the document placement section, enhancing the visibility and clarity of notification information, thereby preventing documents from being overlooked and reducing the risk of them falling.

AI summary
A cover that covers side surfaces of a document conveyance path and a paper feeder in a direction orthogonal to a document conveyance direction and a notifier that notifies information on a document placement section are included. The cover has a first side surface disposed along the document conveyance direction and a second side surface disposed from an end of the first side surface on the paper feeder side toward the document placement section. The notifier includes a displayer that displays the information by light. The displayer includes a first displayer disposed on the first side surface and a second displayer disposed on the second side surface toward the document placement section. The first displayer and the second displayer each have a horizontal length that is longer than a vertical length.
