Disc Conveying Device Route Adjuster Positioning Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc conveying devices face challenges in accurately positioning disc-shaped recording media during conveyance, leading to potential misalignment and complexity in the mechanism, which affects the storage process in disc cartridges.
Innovation Solution
The implementation of a disc conveying device with route adjusters that are pressed and turned by the conveyed disc-shaped recording medium, featuring positioning grooves and protrusions to ensure precise alignment and storage, utilizing a return spring to maintain the adjusters in a neutral position and a guiding face for smooth insertion into holding grooves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a positioning mechanism is provided to perform positioning of the disc-shaped recording medium at an appropriate position as to the disc cartridge, then positional accuracy is improved, but the mechanism becomes complicated
Solution Approach 1:
The disc-shaped recording medium itself performs the positioning function by pressing and turning the route adjuster during conveyance. The leading end portion of the disc automatically engages with the positioning groove and positioning protrusion, eliminating the need for separate positioning mechanisms while achieving accurate positioning in the disc cartridge
Solution Approach 2:
Instead of using a complex positioning mechanism to position the disc, the invention inverts the approach by having the disc's own movement and shape perform the positioning function. The disc's leading end portion acts as the positioning element, turning the route adjuster to the appropriate angle, thereby simplifying the overall mechanism while maintaining positioning accuracy
2Ease of operation
If the disc-shaped recording medium is held from peripheral sides by arm portions and engaging claws, then the disc can be conveyed, but positioning accuracy deteriorates due to assembly variations
Solution Approach 1:
The route adjuster serves as an intermediary element between the engaging claws and the disc cartridge. It receives the disc from the claws, performs positioning through its grooves and protrusions, and then transfers the disc to the cartridge, thereby decoupling the conveyance function from the positioning function and improving accuracy
Solution Approach 2:
The conveying mechanism is segmented into distinct functional components: the engaging claws handle disc pickup, the route adjuster handles positioning and transfer, and the disc cartridge handles storage. This segmentation allows each component to be optimized for its specific function, with the route adjuster providing precise positioning independent of assembly variations in other components

AI summary
A disc conveying device includes a route adjuster which is pressed and turned by a disc-shaped recording medium being conveyed in a direction orthogonal to a central axis direction in a lead-in direction of being extracted and led in from a disc cartridge and an ejecting direction of being stored in the disc cartridge after being ejected; wherein a positioning groove is formed to the route adjuster, in which a peripheral portion of the disc-shaped recording medium is inserted at the time of the disc-shaped recording medium being conveyed, so as to position the disc-shaped recording medium.
