Printer Rib Member Linear Tape Path Peeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers face issues with increased feeding resistance and obstruction when trying to peel the print-receiving layer and adhesive layer from the separation material layer, as the pressing roller contacts the print-receiving tape, causing the feeding path to become non-linear.
Innovation Solution
A printer design featuring a first rib member above the feeding path between the sandwiching and support positions to maintain a linear tape path, reducing contact surface area and preventing loose states, thereby facilitating effective peeling without increasing feeding resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressing roller contacts the print-receiving tape from above to maintain linear feeding path, then peeling effectiveness is improved, but feeding resistance increases and feeding obstruction occurs
Solution Approach 1:
The patent extracts the pressing function from the feeding path by introducing a separate pressing member that acts on the tape after it has been fed through the feeding path. The pressing member is positioned to press the tape at a location removed from the feeding path, thereby maintaining linear feeding while still achieving effective peeling through the pressing action.
Solution Approach 2:
The patent introduces an intermediary structure (the pressing member positioned at a specific location) that mediates between the feeding mechanism and the peeling requirement. This intermediary pressing member applies pressure to the tape at an optimal point to facilitate peeling without interfering with the feeding process, thus resolving the contradiction between peeling effectiveness and feeding resistance.
2Reliability
If the feeding path is made substantially linear, then peeling is achieved effectively, but the pressing roller causes feeding obstruction
Solution Approach 1:
The patent segments the functions of feeding and pressing by positioning the pressing member at a location separate from the feeding path. The feeding path remains linear and unobstructed, while the pressing member independently performs the pressing function at an optimized location to facilitate peeling. This segmentation allows both feeding smoothness and peeling effectiveness to coexist without interference.

AI summary
This disclosure discloses a printer comprises a roll storage part, a platen roller, a printing head, a separation plate, a first discharging exit, a pinch roller, a second discharging exit, and a first rib member. The platen roller contacts and feeds a print-receiving tape. The printing head is provided above the platen roller. The separation plate is provided on the other side than the platen roller and loops back a separation material layer toward a downward side and peel the print-receiving layer and the adhesive layer from the separation material layer. The first rib member is provided to a first section of a feeding path of the print-receiving tape and contacts the print-receiving tape from above, the first section being between a sandwiching position by the platen roller and the printing head and a support position of an end part of the separation plate.
