Abstract
Books with internal mechanization have rotary and linear drive mechanisms which displace objects along linear, non-linear, rotary and three-dimensional paths relative to the book pages are described. Spatially arranged cut-outs in the pages which correspond to the range of motion of the displaced and translated objects allow different moving objects to be viewed at different areas of the book from page to page. Battery powered drive mechanisms with push-button operation accessible from the front of the book enables easy, selective activation of the moving objects, independent of the position of the front cover and pages relative to the back cover. Belt-driven wheels provide inherent clutching action to prevent damage to the drive mechanism. Manually operated embodiments of the various drive mechanisms which produce each of the described motions are also disclosed.
