Cable Holder for Image Recording Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mounting process of cables in Multi Function Devices (MFDs) becomes complicated due to differing cable paths between the upper and lower units, leading to decreased work efficiency and quality defects when the upper unit is rotated relative to the lower unit.
Innovation Solution
An image recording apparatus with a holder that supports and organizes cables, allowing them to extend in a direction intersecting with the rotation axis, and positions them differently in the first and third directions to reduce noise interference and improve handling during assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the FFC and wiring harness extend in parallel to reduce noise interference, then noise influence is reduced, but the mounting process becomes complicated and work efficiency decreases
Solution Approach 1:
The patent divides the cable management into separate segments: the FFC extends in a first direction while the wiring harness extends in a second direction intersecting with the first direction. This segmentation allows each cable to be routed independently through different paths, reducing noise interference while maintaining manageable mounting complexity through structured separation.
2Ease of manufacture
If the cable paths are greatly different from each other to simplify mounting, then mounting process is simplified, but noise interference between cables increases
Solution Approach 1:
The patent introduces a third dimension by having cables extend in different directions (first direction for FFC, second direction intersecting with the first for wiring harness) rather than simply separating them in parallel. This dimensional approach simplifies mounting by creating distinct spatial paths while maintaining adequate separation to reduce noise interference.
3Device complexity
If cables are attached and detached in a small exposed space during rotation, then structural compactness is maintained, but mounting quality and work efficiency decrease
Solution Approach 1:
The patent prepares cable connection points and routing paths in advance within the structural design, allowing cables to be attached and detached at predetermined locations even in compact spaces. This preliminary preparation of connection interfaces maintains structural compactness while ensuring mounting quality through pre-planned access points.

AI summary
An image recording apparatus includes: a first housing comprising a recording portion and a first control device; a second housing comprising a second control device and supported by the first housing to be rotationally movable between a close position and a distant position by rotationally moving about a first axis extending in a first direction; a first cable and a second cable electrically connecting the first control device to the second control device; and a holder having a supported portion and holding the first cable and the second cable. In the first housing, at least a part of the holder extends in a second direction and the holder holds the first cable and the second cable such that the first cable and the second cable extend in the second direction and are respectively disposed at positions different from each other in the first direction and in a third direction.
