Generally, when the medium is fed out from a holding unit that holds a rotating shaft capable of winding the medium in a roll shape, a force is applied to the holding unit in a direction in which the medium is pulled. Then, a force is also applied to the support portion that supports the holding portion in a direction toward the holding portion.
As described above, when a force is applied to the support portion, the support portion may be bent to reduce the medium feeding accuracy, or the medium may vibrate.

In the conventional support device, when the medium is pulled with a strong force, the force applied to the support portion cannot be sufficiently suppressed. However, there are many cases where it is difficult to suppress the force applied to the support part, for example, the medium must be pulled with a strong force. Therefore, it is desired to disperse the force applied to the support portion instead of suppressing the force applied to the support portion.
