The end of the roll is dispensed through the slit provided with a serrated edge. The spindle is screw-threaded at into a knob, rotation of which enables the paper to be dispensed. Unscrewing of cap enables the roll to be renewed or replaced. The lower end of the spindle is received in member,  FIG. 2 . 
   The pen includes a segmented roll of paper E rolled inside a pen with a cover or Window B that can be closed or opened to expose the paper by means of a hinged door. 
   While these devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
