Abstract
An interactive talking book and audio player assembly, the back cover of the book having an ROM module attached to its end margin in which is stored digitally recorded spoken texts corresponding to texts printed on pages of the book. Printed on the end margin of each book page that carries a printed text is a page-identifying binary bar code formed by reflective and non-reflective elements. Associated with the book is an audio player having a base inlet adapted to receive the end margin of the back cover and to bring the terminals of the ROM module into engagement with inlet contacts connecting the module to a speech unit for converting the digitally-recorded texts into audio signals which are amplified and reproduced. When the pages of the book are turned, they overlie the base inlet of the player, the bar code on the open page being then exposed to ambient light. The code elements in the code which are reflective direct the light toward an array of light sensors mounted above the inlet and those which are non-reflective do not, to produce binary signals indentifying the open page. The page-identifying signals are applied to a sensor interface and are transferred thereby to the sp…
