A protector provided with a guide surface for guiding the print medium, and rotating the protector so that the guide surface is inclined with respect to the transport path so as to face an end of a medium passing through a gap between the guide and the print head. And a protector rotating means.

In this case, when the end of the medium passes through the gap between the guide and the protector, the guide surface of the protector is inclined and directed toward the end of the medium. It is not locked to the end face.
Therefore, there is no wrinkling of the medium, no change in the transport amount of the medium to change the actual printing position, and no jam.

Further, since the medium is curved toward the platen along the guide surface when passing through the print head, the medium does not hit the end of the guide on the print head side.
