A regulation device regulates movement in a width direction of a rolled sheet which is a recording medium of a printer. The regulation device includes: a first rack gear connected to one guide support unit supporting the rolled sheet so that movement to one side of the width direction is regulated, and provided to be movable in the width direction; a second rack gear connected to the other guide support unit supporting the rolled sheet so that movement to the other side of the width direction is regulated, and provided to be movable in the width direction; a pinion gear engaging with the first and second rack gears; and a regulation gear that engages with the pinion gear to rotate, includes a locked portion in which a plurality of steps are formed along a curved line forming a part of a spiral wound in a rotation direction of the regulation gear if the first and second rack gears are moved outward in the width direction from a rotation shaft center of the regulation gear toward a diameter outside, and regulates movement of the first and second rack gears by locking the locked portion.
