Rolled medium accommadation device and liquid ejection device

A rolled medium accommodation device comprising:

• a rolled medium accommodation unit configured to accommodate a rolled medium having an elongated medium wound into a roll, and to swing around a first shaft;
• a lever member configured to swing around a second shaft in conjunction with swinging of the rolled medium accommodation unit;
• a shaft member configured to move in a direction intersecting an axial direction of the second shaft while being engaged with a guiding part formed in the lever member;
• and
• an urging unit axially supported at one end on the shaft member and configured to urge the shaft member and to apply rotational torque around the second shaft to the lever member so that, due to the rotational torque around the second shaft applied by the urging unit, the rolled medium accommodation unit is subjected to force whereby the rolled medium accommodation unit is swung in the direction opposite that of gravity around the first shaft from a low position in the direction of gravity to a high position that is higher than the low position, and the shaft member moves so that a distance between a center of the shaft member and a center of the second shaft is greater in the high position than in the low position.
