Medium Discharging Device Stacker Recess for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium-discharging devices with stoppers in the stacker increase the size of the apparatus, compromising alignment performance and efficiency in stacking media of varying sizes.
Innovation Solution
A medium-discharging device with a housing section featuring a recess, a discharging section, and a stacker that can be opened/closed, incorporating a stopper that switches between a regulating and stored state, allowing the stopper to enter the recess when closed, thereby reducing the device's size and enabling better alignment of media through selective stopper use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a stopper is provided in the stacker to regulate medium position, then alignment performance is improved, but the thickness of the stacker increases the apparatus size
Solution Approach 1:
The stopper is stored within a recess formed in the housing section when not in use. This nesting arrangement allows the stopper to be integrated into the housing structure, eliminating the need for increased stacker thickness to accommodate the stopper, thus resolving the contradiction between alignment performance and apparatus size
Solution Approach 2:
The stopper is designed to be movable between a stored state (within the recess) and a regulating state (extending from the stacker). This dynamic configuration allows the stopper to provide alignment functionality only when needed, while maintaining a compact apparatus size when the stopper is retracted, thereby resolving the contradiction between alignment performance and stacker thickness

AI summary
A medium-discharging device includes: a discharging section that discharges a medium; a stacker that is configured to stack the medium on a mounting surface and, in a closed state, has the mounting surface facing the housing section; and a first stopper and a second stopper that are configured to switch between a regulating state in which the stopper is in contact with a leading end of the medium and a stored state in which the stopper is stored in the stacker, in which the second stopper is provided at a position which is between the discharging section and the first stopper and at which the second stopper faces the recess when the stacker is in the closed state, and at least a portion of the second stopper enters the recess when the second stopper is in the stored state and when the stacker is in the closed state.
