Pivoting Scanner Unit for Ink Refill Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face a trade-off between easy ink level checking and user convenience, as enlarging the viewing portion to check ink levels reduces the size and usability of the operation panel.
Innovation Solution
The recording apparatus features a scanner unit that pivots to expose ink tanks, allowing the panel unit to tilt and operate in both open and closed states, with a viewing portion on the casing and an injection port outside the scanner unit, enabling easy ink level checking and refilling without compromising panel size or user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If the viewing portion is increased in size to enable easy checking of the remaining amount of ink in the ink tank from outside the apparatus, then the ease of viewing ink level is improved, but the operation panel becomes relatively small and difficult to use, reducing user convenience
Solution Approach 1:
The patent relocates the viewing portion from the front surface (2D plane) to the side surface of the casing, utilizing a different spatial dimension. This allows the viewing window to be positioned on the side wall portion, separate from the front surface where the operation panel is located, thereby resolving the conflict between viewing size and panel size by distributing these functions across different spatial planes.
Solution Approach 2:
The patent divides the casing surface into distinct functional zones: the front surface houses the operation panel while the side surface houses the viewing portion. This segmentation of functional areas allows each component to be optimized independently - the operation panel can be large and user-friendly on the front surface, while the viewing portion can be adequately sized on the side surface without compromising either function.
2Ease of operation
If the scanner unit is designed to pivot and open for ink refilling, then the ease of refilling is improved, but the device complexity increases due to additional pivot mechanisms and lock portions
Solution Approach 1:
The scanner unit is designed to serve multiple functions: it acts as both the document scanning component and the access mechanism for ink refilling. By integrating the ink tank access function into the existing scanner unit structure, the patent avoids adding a separate refilling mechanism, thereby reducing overall device complexity while maintaining ease of refilling operations.
Solution Approach 2:
The scanner unit's pivot mechanism is designed to be operated by the user without requiring additional tools or complex procedures. The user simply opens the scanner unit to access the ink tank for refilling, making the refilling process self-service oriented. The lock portion automatically secures the scanner unit when closed, eliminating the need for manual locking mechanisms.

AI summary
A recording apparatus includes a recording head, an ink tank that is disposed above the recording head, a carriage on which the recording head and the ink tank are mounted, a scanner unit that is attached to the upper portion of the casing via a pivot shaft so as to pivot with respect to the casing and that reads a document placed on the document table, and a panel unit in which the scanner unit is attached to an end portion disposed on the opposite side to the pivot shaft and is configured to tilt between a first orientation and a second orientation closer to the document table than the first orientation, and by pivoting the scanner unit with respect to the casing to expose the ink tank, ink is injected from the refill container into the ink tank and the remaining amount of liquid is viewed.
