Processing when Medium is Jammed in Reversing Unit
A medium fed from a medium storage unit (not illustrated) disposed at a bottom portion of the device body 5 of the recording device 1 is transported along the transport path 2, and ink is ejected in a recording region of the recording unit 7 so that recording is performed on a first surface of the medium. The medium on which the recording was performed is transported through the transport path 2, is reversed by being transported through the reversing unit 9, and is made to pass through the recording region of the recording unit 7 again. Recording is performed on a second surface of the medium by the recording unit 7, and the medium is fed to a discharge unit (not illustrated).
When the medium is jammed in the reversing unit 9, firstly, the device body 5 is pulled out from the outer case 3 thus bringing about a state where a user can get access to the reversing unit 9. Next, the reversing unit 9 is pulled out from a position at which the reversing unit 9 is held by the holding portions 25 in a detaching direction in the attaching/detaching direction P.

In a state where the reversing unit 9 is pulled out from the device body 5, the user handles the jam of the medium in the reversing unit 9. The reversing unit 9 in which the jam of the medium has been eliminated is pushed in the attaching direction in the attaching/detaching direction P, and is again brought into a state where the reversing unit 9 is held by the holding portions 25. At the time of pushing the reversing unit 9, the coupling portion 17 is in a state where the coupling portion 17 couples the first frame 13 and the second frame 15 to each other.
