Printing Apparatus Movable Disposing Stand Reduces Unprinted Margin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses require space for the disposing stand to move, leading to a separation between the cutting position and the printing head, resulting in a longer unprinted margin on the printing medium, which can cause waste and inefficiency in printing.
Innovation Solution
A printing apparatus with a movable disposing stand that shifts orthogonal to both the conveyance direction and the thickness direction of the printing medium, allowing the cutting blade to pivot from a non-cutting to a full-cut position, thereby shortening the unprinted margin by enabling precise cutting without lengthening the cutting path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the disposing stand moves along the conveyance direction between first and second facing positions, then the cutting operation can be performed, but the position where the tube is cut is separated from the printing head and the end portion of the tube lengthens
Solution Approach 1:
The disposing stand is made movable in a direction orthogonal to the conveyance direction (third direction) instead of moving along the conveyance direction. This dimensional change allows the cutting blade to approach the printing head closer without requiring the disposing stand to travel along the tube's path, thereby reducing the unprinted margin and tube waste while maintaining cutting functionality.
Solution Approach 2:
The cutting blade is made movable from a non-cutting position to a full cut position, allowing it to dynamically adjust its position relative to the printing head. This dynamic positioning enables the blade to be closer to the printing head during operation, reducing the required margin without compromising the cutting operation.
2Adaptability or versatility
If the disposing stand moves between first and second facing positions along the conveyance direction, then partial cut and full cut operations can be performed, but a space for the disposing stand movement must be secured
Solution Approach 1:
The disposing stand's movement is redirected from the conveyance direction (first direction) to a direction orthogonal to both the conveyance direction and the thickness direction (third direction). This allows the apparatus to maintain full cutting functionality while reducing the space required in the conveyance direction, thereby decreasing the overall apparatus footprint.
Solution Approach 2:
The cutting blade is made dynamically movable from a non-cutting position to a full cut position, enabling the blade to reach the printing head closely without requiring the disposing stand to occupy a large space along the conveyance direction. This dynamic adjustment reduces the static space requirements while maintaining cutting versatility.

AI summary
A printing apparatus includes: a conveying unit; a printing unit; a disposing stand provided on a downstream side of the printing unit in a first direction, the disposing stand having a disposing section where a printing medium is disposed; a cutting blade that cuts the printing medium disposed in the disposing section; and a supporting member that supports the cutting blade movably from a non-cutting position, via a partial cut position, to a full cut position. The non-cutting position is a position where a blade edge is separated from the printing medium disposed in the disposing section. The partial cut position is a position where the cutting blade cuts a part of the printing medium in a second direction. The full cut position is a position where a blade edge passes beyond the disposing section to fully cut the printing medium in the second direction.
