A first conveyance path and a second conveyance path are formed in a housing. The first conveyance path extends in a conveyance direction to reach a first discharge port for discharging a sheet. The second conveyance path extends in the conveyance direction at a position higher than the first conveyance path to reach a second discharge port for discharging a sheet. The second discharge port is located at a position upstream of the first discharge port in the conveyance direction. A first print engine is provided at the first conveyance path. The first print engine is configured to print an image by using a recording agent on a sheet conveyed along the first conveyance path. A second print engine is provided at the second conveyance path. The second print engine is configured to print an image by using a recording agent on a sheet conveyed along the second conveyance path.

A recording device includes a recording unit, a discharge roller unit, a medium receiving tray, a motor serving as a power source of the discharge roller, a power transmission unit that is configured to switch between a power transmission state in which power of the motor is transmitted from the motor to the medium receiving tray, and a power non-transmission state in which the power of the motor is not transmitted from the motor to the medium receiving tray, and a restriction unit that is configured to switch between a restriction state in which the restriction unit restricts displacement of the medium receiving tray when the power transmission unit is in the power non-transmission state, and a non-restriction state in which the restriction unit does not restrict the displacement of the medium receiving tray when the power transmission unit is in the power transmission state.
