Abstract
A rolled medium accommodation device includes a rolled medium accommodation unit which swings around a first shaft, a lever member which swings around a second shaft in conjunction with swinging of the rolled medium accommodation unit, a shaft member capable of moving in a direction intersecting an axial direction of the second shaft, and urging unit configured to apply rotational torque around the second shaft to the lever member. Due to the rotational torque, the rolled medium accommodation unit is subjected to force whereby the rolled medium accommodation unit is swung in a direction opposite that of gravity around the first shaft from a low position to a high position higher than the low position, and the shaft member moves so that the 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.
