ABSTRACT:
The pages of a book are placed on a long strip of paper for making a scroll. The machine for winding the scroll has rollers positioned for displaying any desired portion to be read. A motor for rotating the rollers is controlled by a magnetic switch that is easily operated by inflating an air bag. The bag may be inflated either by having a person squeeze a bulb connected through a tube to the bag, or by having a severely handicapped person hold the end of a tube in his mouth and blow into the tube.
