Print Media Stacking Layout for Compact Orthogonal Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses that sort print media by moving the stacking part obliquely increase in size, leading to space inefficiencies.
Innovation Solution
A printing apparatus with a stacking part that moves in orthogonal directions to sort print media, incorporating a conveyance system with a first stacking part at two positions and a liquid storage part above the stacking part, allowing for compact design and efficient media sorting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stacking part is moved obliquely to sort print media, then the sorting function is achieved, but the apparatus size increases
Solution Approach 1:
The stacking part is configured to move in a second direction intersecting with the conveyance direction (first direction), enabling sorting through orthogonal movement rather than oblique movement. This dimensional change allows the stacking part to achieve sorting positions without requiring diagonal space, thereby reducing the overall apparatus footprint while maintaining the sorting capability.
2Productivity
If the stacking part is moved diagonally to prevent overlap of sorted bundles, then sorting efficiency is improved, but the required space increases
Solution Approach 1:
By moving the stacking part in an direction intersecting with the conveyance direction rather than diagonally, the patent achieves bundle separation in a perpendicular dimension. This allows sorted bundles to be positioned at first and second positions without overlapping, maintaining sorting efficiency while minimizing the horizontal space required for the operation.
Solution Approach 2:
The stacking part is configured to move between a first position and a second position in the intersecting direction, segmenting the stacking area into distinct zones. This segmentation allows different bundles of print media to be sorted into separate positions, preventing overlap and enabling efficient sorting within a compact space.
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 orthogonal movement of the stacking part reduces the apparatus size while maintaining efficient sorting and usability, enhancing visibility and reducing user burden.
Implementation Method 1
a print head configured to perform printing by ejecting liquid onto the print medium conveyed by the conveyance part
Implementation Method 2

AI summary
A printing apparatus includes: a conveyance part configured to convey a print medium in a first direction; a print head configured to perform printing by ejecting liquid onto the print medium conveyed by the conveyance part; a first stacking part configured to stack the print medium, on which printing has been performed by the print head, at a first position and at a second position different from the first position in a second direction intersecting with the first direction; and a liquid storage part configured to contain the liquid to be supplied to the print head. The liquid storage part is arranged above the first stacking part.
