ABSTRACT:
A page turning device is provided in which a first elongated arm is rotatably mounted for circular motion substantially parallel to but above the plane of the volume. A page lifting facility cooperates with the rotation of the first elongated arm to permit the first elongated arm to rotate between a lifted upper leaf and the remainder of the leaves of the volume. Continued rotation of the first elongated arm turns the upper leaf and positions the arm for turning of the next leaf. In this manner an unlimited number of leaves may be sequentially turned by a mechanically simple device which is immediately ready for use when a volume is positioned thereon.
