Abstract
A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.
