[Problems to be solved by the device]

 However, the roll paper R such as toilet paper has considerable elasticity in the roll radial direction, and when the roll paper R is transported in the vertical direction, the conventional roll paper supply device 101 described above There was such a problem. That is, when the first stopper 103 is in the stop operation state and the second stopper 104 is in the stop release state, the conveyor 102 is continuously operated, so that the first stopper 103 stops the operation. The roll paper R on the leading side is sequentially pressed by the roll papers R, R ... Each of the following rolls, and is compressed and deformed into an elliptical shape as shown by a chain line R'in FIG. ), The roll paper R may not correspond exactly to the position of the pressing plate 104a of the second stopper 104, and at that time, the second stopper 104 may roll the roll paper R in the predetermined order (sixth). The next (seventh) roll paper may be pressed, and the number of roll papers sent to the lifter device 3 side becomes larger than the normal number. Troubles such as Ri there is a problem that occurs.

In view of the conventional problems as described above, the present invention can always supply an accurate number of roll papers having elasticity in the roll radial direction on the lifter device in a vertical posture. It is an object of the present invention to provide a roll paper supply device which has
