To suppress an increase in size in a width direction and prevent a winding shaft from rotating in a direction opposite to a winding direction without providing extra space in a printer. A printer 100 includes a body 10; a cover 20 configured to open and close relative to the body 10; a winding shaft 60 in the cover 20 for winding an ink ribbon 2; a lock member 80 (regulation member) in the cover 20 and configured to change a position in accordance with an open and closed state of the cover 20; a winding gear 61 (passive member) connected to an end of the winding shaft and configured to receive driving force; and a ribbon flange 70 provided axially inside the winding gear 61 (passive member) and configured to rotate with the winding shaft 60. The ribbon flange 70 includes a cam face 74 on the inner side than an outer circumference of the ribbon flange. A radial distance of the cam face 74 from a center axis C of the shaft 60 varies in accordance with a rotation angle position of the ribbon flange 70. An upper end portion 83 of the lock member 80 restricts the rotation of the ribbon flange 70 by contacting the cam face 74 when the cover 20 is open.
