Dual Cover Segmentation for Mobile Printer Dust Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile recording apparatuses face dust and debris entry issues due to their design, which exposes the interior when in use, leading to potential faults and malfunction.
Innovation Solution
A dual open/close body system where the first open/close body covers the setting port and the second open/close body covers the remaining upper portion, both aligning to form a cohesive shape when closed, allowing only the setting port region to be exposed during use, thus minimizing dust entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single open/close body covers the entire apparatus upper face including the setting port, then dust entry is suppressed when not in use, but the entire apparatus upper face must be opened during recording which increases dust entry risk
Solution Approach 1:
The upper face cover is divided into two separate open/close bodies: a first open/close body that opens and closes a first region including the setting port, and a second open/close body that opens and closes a second region other than the first region. This segmentation allows selective opening of only the necessary region during recording operations, maintaining dust suppression while enabling functionality.
2Reliability
If the first open/close body has the same dimension as the apparatus main body in the width direction, then the cover provides complete protection, but it prevents selective exposure of only the setting port region during use
Solution Approach 1:
The first open/close body is designed with a dimension in the width direction that is smaller than the dimension of the apparatus main body in the width direction. This local differentiation in dimensions enables the first open/close body to cover only the setting port region when closed, and to be selectively opened during recording operations without exposing the entire apparatus upper face, thus maintaining dust suppression while enabling ease of operation.

AI summary
A printer includes a first upper face cover and a second upper face cover. The first upper face cover is formed such that when a medium is set in a setting port, the width direction of the medium is a first direction, and the first upper face cover has a smaller dimension in the first direction than a dimension of an apparatus main body in the first direction. The first upper face cover in a closed state is included inside the second upper face cover in plan view when the second upper face cover is in a closed state. The first upper face cover and the second upper face cover both in the closed states form a shape that corresponds to an outline of an upper portion of the apparatus main body.
