Recording Apparatus Air-Blowing Box With Retractable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses face challenges in maintainability, particularly during maintenance of the air blowing mechanism and paper passing operations for continuous sheet-like recording materials.
Innovation Solution
The recording apparatus is designed with an air blowing portion that includes an air blowing box with a blow-out port and a holding portion that allows the air blowing box to be movable between a position facing the sheet conveyance path and a retracted position, facilitating easy attachment and detachment for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the air blowing box is fixed to the frame body side plate, then the structural stability is improved, but the maintainability deteriorates
Solution Approach 1:
The air blowing box is divided into a detachable component that can be separated from the frame body side plate. The holding portion provides attachment/detachment functionality while the air blowing box itself remains a separate, serviceable unit. This segmentation allows the box to be fixed during operation for stability but easily removed for maintenance.
2Reliability
If the air blowing box is fixed in position, then the functional reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The holding portion enables the air blowing box to transition between fixed and movable states. During recording operations, the box is held in a fixed position facing the conveyance path for reliable air blowing. During maintenance or paper passing operations, the box can be moved to a retracted position. This dynamic capability resolves the contradiction between fixed positioning for reliability and movability for ease of operation.
3Reliability
If the air blowing box is positioned to face the conveyance path, then the recording functionality is improved, but the accessibility for maintenance deteriorates
Solution Approach 1:
The holding portion allows the air blowing box to be positioned in two distinct states: a first position where the blow-out port surface faces the conveyance path for optimal recording functionality, and a second retracted position where the box is moved away from the conveyance path to provide accessibility for maintenance. The movable design enables transition between these states, resolving the contradiction between functional positioning and maintenance accessibility.

AI summary
A recording apparatus includes a conveyance portion that conveys a sheet, and an air blowing portion that applies an air current to the sheet conveyed by the conveyance portion, wherein the air blowing portion includes an air blowing box that has an air blow-out port through which an air current to be applied to the sheet is blown, and holding portions that hold the air blowing box and are configured to be movable such that the air blowing box takes a first position where a blow-out port surface provided with the air blow-out port faces a conveyance path of the sheet and a second position where the blow-out port surface is further away from the conveyance path than when the first position is taken, and the air blowing box is configured to be attachable to and detachable from the holding portions.
