Abstract
The present invention refers to the singlehandedly operated dispenser for rolled sheets of paper for perforated and unperforated paper sheets alike. The spindle with roll of paper placed over-handedly is moving down and against the back wall along the chutes in the form of elongated slots, grooves or tabs in side walls and providing continuous contact of the outside surface of the paper roll with the back wall covered by antiskid layer, and thus keeping the roll of paper immobilized and in fixed position against the back wall, and preventing run-off when the amount of paper on the roll is getting smaller. Drawing sheet of paper upward from the roll disengages the roll from the back wall, while drawing downward increases engagement of the outside surface of the roll with back wall that allows separating the required length from the roll leaving previously separated edge on top of the roll for easy access at next draw.
