ール紙の残量検出装置。[Claims for Utility Model Registration] A paper storage unit that retractably stores a roll of paper wound into a roll; and a pressure lever disposed on one side of the paper storage unit and in contact with one end face of the roll paper to press the other end face of the roll paper against the other side face of the paper storage unit. , when the roll diameter of the roll paper is equal to or greater than a predetermined value, the roll is moved by both the own weight of the roll paper against the pull-out force of the roll paper by the paper feeding means and the holding force due to the pressing of the pressure lever. When the paper is held at a position in contact with the detection switch and the roll diameter of the paper roll becomes less than a predetermined value, the paper roll is separated from the detection switch by the drawing action of the paper feeding means, and the paper is moved away from the detection switch. A remaining roll paper amount detecting device, wherein a pressing force of the pressure lever is set so as to operate the pressure lever.
