US Patent 7187395 Roll paper feeding device and photo printer

A roll paper feeding device includes a paper feed roller, a flange holder, a flange pressing portion, a roll paper pressing lever, a housing containing these components therein, and a cover arranged above the housing. The flange holder has a recess having wide opening at an upper surface, and a shaft of the flange axially supporting the roll paper is placed in the recess. The flange pressing portion is provided on the cover, and when the cover is open, the flange pressing portion is moved toward the center of rotation of the cover, by means of a rotating member, a base member and a spring. Consequently, the flange supporting the roll paper on its shaft can easily be set in the flange holder.
