Automatic seat paper supply stool

Abstract

Abstract PURPOSE:To block a seat paper surely from being drawn out even if a stool is held while a seat paper is drawn out by controllably driving a roller member according to ON-OFF signals of a seating detecting means. CONSTITUTION:When a stool 3 is held down through a seat paper from above or one is seated on the stool 3 while the seat paper is drawn out, the pivot shaft 61 of a seating detecting means 60 is depressed to lower a sensor activating lever 68 through a lever pressing piece 67 for turning ON a photosensor PS (operating the seating detecting means 60). Thus, a detecting signal of a photocoupler PC is inputted from a seating detecting circuit 54. Then, a photocoupler PC1 is turned OFF to quickly stop a motor 16. Thus, the drawing- out of the seat paper is temporarily stopped. When the stool 3 is released from the depression, the conduction between a photodiode d1 and a photo transistor T1 is secured by a screening plate 72 to turn OFF the photosensor PS as non- conductive one. As a result, the photocoupler PC1 is turned ON to activate the motor 16 and restart the drawing-out of the seat paper.
