AI Technical Summary
Technical Problem
Conventional medium conveying devices face issues with sheet damage due to collisions between sheets during conveyance, particularly when the conveyance of leading sheets is temporarily stopped for skew correction or timing adjustments.
Method used
The media transport device incorporates a separation unit, a first and second transport unit, and a control unit that adjusts the speed of the feeding member based on medium length, employing a separation control method to prevent collisions by varying the speed of the feeding member relative to the second transport unit.
Benefits of technology
This approach effectively reduces sheet damage by minimizing collisions between sheets, enhancing the usability and reliability of the medium conveyance process.

Abstract
To provide a media transport device and a recording device that minimize damage to the media. [Solution] The media transport device 100 includes a separation unit 164 for separating the media P, a first transport unit 121 located downstream of the separation unit 164 and capable of transporting and stopping the media P, a second transport unit 122 located between the separation unit 164 and the first transport unit 121 and transporting the media P to the first transport unit 121, a control unit 111, and a length detection unit for detecting the length of the media P along the transport direction. The separation unit 164 includes a feeding member 164a for transporting the media P and a separation member 164b for separating the media P by clamping the media P together with the feeding member 164a. The control unit 111, when the length of the media P is a first length, performs a first separation control to drive the feeding member 164a at the same speed as the second transport unit 122 based on the first length, and following the first separation control, performs a second separation control to drive the feeding member 164a at a lower speed than the second transport unit 122.
