Medium transport device and recording apparatus

A medium transport device comprising:

• a separator configured to separate a medium;
• a first transport unit located downstream of the separator in a transport direction of the medium and configured to transport and stop the medium;
• a second transport unit located between the separator and the first transport unit in the transport direction and configured to transport the medium to the first transport unit;
• a control unit configured to control the separator and the second transport unit;
• and
• a length detection unit configured to detect a length of the medium along the transport direction, wherein
• the separator includes
• a feeding part configured to transport the medium in the transport direction, and
• a separation member configured to separate the medium by sandwiching the medium together with the feeding part, and
• when the length of the medium is a first length, the control unit executes first separation control of driving the feeding part at a same speed as a speed of the second transport unit based on the first length, and executes second separation control of driving the feeding part at a speed less than the speed of the second transport unit subsequently to the first separation control.
