Foldable Straight-Path Discharge Tray for Space-Saving Sheet Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices that discharge sheets through a straight path require a large installation space due to the need for a straight path discharge tray that occupies a significant area.
Innovation Solution
A transport device with a straight path discharge tray that can pivot between an open state for sheet discharge and a closed state to save space, featuring a pivotable first and second tray section and an engagement mechanism to stabilize the closed position, along with a detection system to ensure proper operation.

Engineering Contradiction Analysis
1Ease of operation
If a straight path discharge tray is provided for receiving sheets discharged through a straight path, then sheet discharge functionality is improved, but the installation space required increases significantly
Solution Approach 1:
The discharge tray is designed as a movable structure that can pivot between an open state for sheet discharge and a closed state for space saving. The first tray section and second tray section are connected via a pivot mechanism, allowing the tray to dynamically change its configuration based on operational needs, thus resolving the contradiction between providing discharge functionality and minimizing installation space.
Solution Approach 2:
The discharge tray utilizes vertical space by pivoting upward to a closed position where it partially covers the casing, rather than extending horizontally. This dimensional transition from horizontal extension to vertical orientation reduces the horizontal footprint while maintaining the capability for sheet discharge when needed.
2Area of stationary object
If the discharge tray is made movable to save space, then installation space is reduced, but the structural complexity increases
Solution Approach 1:
The discharge tray is divided into multiple sections (first tray section and second tray section) that can move independently. This segmentation allows each section to be optimized for its specific function while reducing the overall complexity compared to a single large movable tray, as each section can be smaller and simpler in design.
Solution Approach 2:
When the discharge tray is in the closed state, the second tray section nests over the first tray section, and the entire assembly partially covers the casing. This nested configuration minimizes the space occupied while maintaining structural integrity, and the nesting mechanism itself is simpler than a fully extended movable tray structure.

AI summary
A transport device includes a supply tray that supplies a sheet, a casing including a straight transport route through which the sheet is linearly transported, a reversing transport route through which the sheet is transported so as to be reversed, the reversing transport route being branched from the straight transport route, and an image reading device that reads an image on the sheet being transported through the straight transport route, and a straight path discharge tray including a first tray section pivotably attached to the casing, and a second tray section pivotably attached to the first tray section. The straight path discharge tray is switchable between an open state in which the first tray section and the second tray section form a receiving surface for the sheet, and a closed state in which the first tray section and the second tray section partially cover the casing.
