a sheet holder by which the sheet in the rolled shape is rotatably held and including at least one side plate movable in a width direction of the sheet and contacting a side surface of the sheet;
a printing head by which an image is printed on the sheet that has been conveyed from the sheet holder;
a buffer unit between the sheet holder and the printing head and including a plate-shaped member that is connected to an elastic member that generates an elastic force by which the conveyed sheet is pressed; and
an adjusting unit by which the movable side plate and the buffer unit are connected such that the elastic force varies depending on a location of the side plate, wherein
the adjusting unit includes:
a rotation plate, one end of which is connected to the elastic member, and which rotates when the location of the side plate is changed,
a shaft, one end of which is connected to the other end of the rotation plate,
a first gear connected to the side plate and movable therewith along the width direction,
