Duplex Media Inversion Path Scheduling for Higher Recording Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices that record on both surfaces of a medium struggle to improve user convenience by enhancing throughput.
Innovation Solution
A recording device and method that includes a transport part, recording part, and control part, which allows the second medium to be transported to an inversion path while the first medium is stopped in the inversion path, enabling re-transportation in an inverted state to facilitate double-sided recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the medium is sequentially transported and recorded on both surfaces, then double-sided recording is achieved, but throughput is limited due to sequential processing
Solution Approach 1:
The first medium is transported to the inversion path and stopped in advance before the second medium completes its recording. This preliminary positioning allows the second medium to be transported to the inversion path during the stop period, enabling continuous processing and improved throughput without extending total recording time
2Manufacturing precision
If the transport speed is controlled independently in recording and inversion paths, then recording precision is improved, but device complexity increases
Solution Approach 1:
The transport speeds in the recording path and inversion path are made dynamically adjustable and independently controllable. This allows optimization of recording precision by adapting transport speeds to specific recording requirements while maintaining manageable system complexity through modular control architecture
3Productivity
If the medium is stopped in the inversion path for re-transportation, then double-sided recording is enabled, but operational efficiency decreases
Solution Approach 1:
The stop of the first medium in the inversion path is utilized productively by transporting the second medium to the inversion path during this period. This continuous utilization of available time and space ensures that the stop period does not represent idle time, thereby maintaining operational efficiency while enabling double-sided recording

AI summary
The recording device includes a transport part, a recording part, and a control part that controls the transport part and the recording part. A inversion path is a path for re-transporting a medium to a recording path in a state where a front and back of the medium transported along the recording path are inverted. In a case where the transport part sequentially transports the first medium and the second medium and the recording part performs recording on both surfaces of at least the first medium, the control part transports the second medium on which recording is performed on the first surface by the recording part to the inversion path during a state where the first medium on which recording is performed on the first surface by the recording part is stopped in the inversion path, and re-transports the first medium from the inversion path to the recording path.
