Recording Device Vertical Ejection Roll Accommodating Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recording devices experience a significant size increase in the conveying direction due to the need for a carrying tray to handle ejected recording media, which is inefficient and occupies unnecessary space.
Innovation Solution
A recording device design featuring a roll accommodating unit positioned externally with a carrying unit integrated into the device body's top surface, allowing for vertical ejection and carrying of the recording medium without requiring a continuous carrying tray in the conveying direction, along with a regulating unit to manage downstream movement and a mechanism for easy roll replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carrying tray is installed next to the second side surface to carry ejected recording medium, then the recording medium can be carried, but the surface area over which the entire recording device is installed becomes very large in relation to the conveying direction
Solution Approach 1:
The patent changes the carrying direction from the horizontal conveying direction to a vertical direction. The recording medium is ejected upward through the top surface of the device body, and the carrying function is integrated into the vertical space above the device, eliminating the need for a separate carrying tray that would increase the horizontal footprint.
2Ease of operation
If the roll accommodating unit is positioned outside the device body, then roll replacement is easy, but the device structure becomes more complex
Solution Approach 1:
The roll accommodating unit is designed as a separate, modular component that can be independently positioned outside the device body. This segmentation allows the roll unit to be easily accessed and replaced without disassembling the entire device, while the modular design keeps the added structural complexity manageable.
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
This design minimizes the device's size increase in the conveying direction, enables smooth ejection of long recording media due to gravity, ensures accurate positioning, facilitates easy roll replacement, and prevents media from falling, while allowing for easy removal of carried sheets.
Implementation Method 1
the recording medium can move downstream in the ejecting direction due to the weight of the recording medium itself

AI summary
A recording device includes a device body, a roll accommodating unit accommodating a roll that is a long recording medium wound up into a roll shape, the roll accommodating unit being provided to an exterior of the device body, a recording head that performs recording on the recording medium unwound and conveyed from the roll accommodated in the roll accommodating unit, an ejection conveying unit that ejects the recording medium subjected to recording by the recording head out of the device body, and a carrying unit on which the recording medium ejected by the ejection conveying unit is carried. The carrying unit is formed by a top surface of the device body and a topside surface in a vertical direction of the roll accommodating unit.
