Abstract
A printer includes a body; a cover configured to open and close relative to the body; a winding shaft in the cover for winding an ink ribbon; a regulation member in the cover to change a position in accordance with an open and closed state of the cover; a passive member connected to an end of the winding shaft to receive driving force; and a ribbon flange provided axially inside the passive member to rotate with the winding shaft. The ribbon flange includes a cam face on the inner side than an outer circumference of the ribbon flange. A radial distance of the cam face from a center axis of the shaft varies in accordance with a rotation angle position of the ribbon flange. An upper end portion of the lock member restricts the rotation of the ribbon flange by contacting the cam face when the cover is open.
