Sheet conveying device and image forming system

A sheet conveying device comprising:

• a first rotatable member rotatable about a first rotational shaft, displaceable to a first position where the first rotatable member is closed, a second position where the first rotatable member is opened upward from the first position and a third position positioned between the first position and the second position, and including an engaging portion;
• a second rotatable member rotatable about a second rotational shaft which is disposed in a direction crossing the first rotational shaft, displaceable to a fourth position where the second rotatable member is closed and a fifth position where the second rotatable member is opened upward from the fourth position, and including an engaged portion engageable with the engaging portion;
• and
• an urging portion configured to urge so as to move the first rotatable member toward the first position in a case in which the first rotatable member is positioned in a first range from the first position to the third position, and to urge so as to move the first rotatable member toward the second position in a case in which the first rotatable member is positioned in a second range from the third position to the second position,
• wherein in a state in which the first rotatable member is in the first position and the second rotatable member is in the fourth position, the engaging portion is engaged with the engaged portion, and in a case in which the first rotatable member is moved from the first position to the second position, the second rotatable member is moved to the fifth position and retained.
