Movable Rod Medium-Receiving Member for Banner Printer Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses for banner printing and wide-format printing face challenges in efficiently storing large, stiff, or lightly curled media, as they require significant space and often result in media protrusion or falling due to inadequate storage mechanisms.
Innovation Solution
A recording apparatus with a medium-receiving member that can change posture using a movable rod, allowing for reliable stacking and storage of media regardless of stiffness, by adjusting the rod's position to guide the medium's leading edge into the storage device and prevent protrusion or falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If media are substantially directly stacked in the ejected medium storage portion, then storage capacity is improved, but a large space is necessary in front of the apparatus
Solution Approach 1:
The patent transitions from direct horizontal stacking to a vertical storage configuration where the medium-receiving member is disposed above the floor. The medium is guided to enter the storage portion through a leading edge guide, allowing vertical arrangement that increases storage capacity without requiring additional horizontal space in front of the apparatus.
2Adaptability or versatility
If the medium-receiving member has a fixed posture, then device complexity is reduced, but it cannot accommodate media with different stiffness levels
Solution Approach 1:
The patent introduces a movable rod that can change its position between a first position (not contacting the medium-receiving member) and a second position (contacting the medium-receiving member). This dynamic adjustment allows the rod to modify the posture of the medium-receiving member, enabling adaptation to different media stiffness levels without requiring multiple fixed configurations.
Solution Approach 2:
The patent changes the physical state or configuration parameter of the medium-receiving member by adjusting the rod's position. When the rod is at the second position, it contacts the medium-receiving member to create a substantially horizontal portion, altering the member's posture to accommodate media with varying stiffness characteristics.
3Reliability
If the leading edge of the medium does not enter the ejected medium storage portion, then the medium may fall on the floor, but guiding mechanisms add device complexity
Solution Approach 1:
The patent introduces a leading edge guide as an intermediary component that facilitates the medium's entry into the storage portion. This guide is disposed at the entrance of the ejected medium storage portion and works in conjunction with the medium-receiving member to reliably guide the medium's leading edge inside, preventing the medium from falling on the floor without requiring complex guiding mechanisms.

AI summary
A movable rod member is provided that changes the shape of a medium receiver of a medium storage portion by changing the location of the movable rod member. The location of the movable rod member is changed in accordance with the condition of a medium, so as to change a method of storing the medium.
