Recording Device Movement Unit Common Drive Source
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices face challenges in minimizing cost and size due to the use of separate power sources for different movement mechanisms, such as adjustment cams and rack and pinion mechanisms.
Innovation Solution
A recording device with a movement unit that includes a first movement section for fine adjustments near the medium transport path and a second movement section for larger displacements, both driven by a common drive source, reducing the need for multiple power sources and minimizing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate power sources are used for adjustment cam and rack and pinion mechanism, then each movement section can be independently controlled, but device cost and size increase
Solution Approach 1:
The patent combines two separate power sources (one for adjustment cam, another for rack and pinion mechanism) into a single common drive source. The movement unit includes a drive source that simultaneously drives both the adjustment cam and the rack and pinion mechanism through a unified transmission system, reducing the total number of power sources from two to one, thereby lowering device cost and size while maintaining independent control capability through mechanical transmission design
2Manufacturing precision
If adjustment cam is used for fine positioning near medium transport path, then positioning precision is improved, but device size increases
Solution Approach 1:
The movement unit is segmented into functionally distinct components: an adjustment cam mechanism for fine positioning near the medium transport path, and a rack and pinion mechanism for larger displacements farther from the transport path. This segmentation allows each mechanism to be optimized for its specific function while sharing a common drive source, achieving high positioning precision without requiring a completely separate power source, thus controlling overall device size

AI summary
A recording device (1) includes a recording section (40) configured to move with respect to transport path and a movement unit (110) configured to move the recording section, wherein a movement region of the recording section includes a first region (Am1) and a second region (Am2) farther from the transport path than the first region, the movement unit includes a first movement section (65) configured to move the recording section in the first region and a second movement section (70, 71, 72) configured to move the recording section in the second region, the recording section preforms when transitioning from the first region to the second region, transitions from a state of being moved by the first movement section to a state of being moved by the second movement section and when transitioning from the second region to the first region, transitions from a state of being moved by the second movement section to a state of being moved by the first movement section, and the first movement section and the second movement section are driven by a common drive source (101).
