Image Recording Apparatus Space Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image recording apparatuses face challenges in maintaining high-quality image recording without deforming components due to the moving force of the moving mechanism when adjusting the space between the recording and conveying sections.
Innovation Solution
An image recording apparatus with a moving mechanism that adjusts the space between the recording and conveying sections using space adjustment members and contacting portions, ensuring the force application is coincident with the positioning section to prevent deformation, allowing for precise adjustment of the space to a predetermined value.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a moving mechanism is used to adjust the space between the recording head and conveying section, then the space can be changed between recording and non-recording positions, but the moving force may cause deformation of components
Solution Approach 1:
A positioning section acts as an intermediary between the moving mechanism and the components being positioned. This positioning section includes space adjustment members that contact the components at specific points, mediating the force application to prevent direct transmission of moving forces that would cause deformation while still enabling space adjustment.
Solution Approach 2:
The positioning section applies force at specific localized points (contact points) rather than distributing force across entire surfaces. The space adjustment members contact the head holding section or platen at discrete locations, concentrating the adjusting force locally to achieve positioning without causing widespread deformation.
2Manufacturing precision
If the space between recording head and conveying section is adjusted by contact with space adjustment members, then high-quality image recording can be achieved, but component deformation may occur due to applied force
Solution Approach 1:
The positioning section serves as a mediator that achieves precise spacing without directly applying strong forces to the components. The space adjustment members within the positioning section transmit only the minimal necessary force required for positioning, preventing component deformation while maintaining manufacturing precision.
Solution Approach 2:
The system changes the parameter of force magnitude applied during spacing adjustment. By controlling the moving mechanism to apply only sufficient force for positioning (rather than excessive force), the patent achieves precise space adjustment while preventing component deformation through parameter control.

AI summary
An image recording apparatus is provided with the following a conveying section including a platen which conveys a recording medium, an image recording section which performs image recording with respect to the recording medium conveyed by the conveying section, and a moving mechanism which moves at least one of the image recording section and the conveying section and enables a movement between a recording position in which the image recording is performed and a non-recording position in which the image recording is not performed, and a positioning section which permits the space between the image recording section and the conveying section to have a predetermined value at the recording position. The point of application of a force with which at least one of the image recording section and the conveying section is moved by the moving mechanism is substantially coincident with the positioning section.
