An automatic induction device for turning pages includes a plurality of inner pages, a plurality of conductive rubber pieces, a flexible printed circuit board, and an electronic unit. The inner pages connect with each other on one side and each has a groove on the connected side. The conductive rubber pieces are inserted in the grooves respectively and one end of each conductive rubber piece extends out of the corresponding groove. The flexible printed circuit board has a plurality of connecting finger conductive portions and a connecting end, the connecting finger conductive portions are inserted in the grooves and contact with the conductive rubber pieces, respectively. The electronic unit electrically connects with the connecting end of the flexible printed circuit board. Based on the above assemblies, the automatic induction device for turning pages, electronic audio books and photo albums has more reliable performance, a simple structure and a low cost.
