Abstract: 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.

Abstract: The invention discloses a combined pencil sharpener and an ink stamp being able to give off light. The invention includes a pencil sharpener and a stamp which are slidably engaged together. When a pencil is inserted into an opening of the pencil sharpener, it will move the sharpener towards the stamp and then conduct a circuit contained in a housing of the stamp to allow an LED to give off light. The invention will not only increase the attractiveness of the sharpener but also be very helpful to teach a young user to sharpen a pencil.

Abstract: A writing instrument with sound and illumination functions has a case with an ink cartridge. A chamber is mounted on the case. A buzzer and an IC board are installed in the chamber. The IC board has an LED mounted on the upper surface and two battery seats with a battery in each seat mounted on the bottom surface. When writing, the circuit consisting of the buzzer, the LED, the IC board and the batteries is completed so that the LED emits light and the buzzer makes a sound or plays music.

Abstract: The structure of an ink stamp emitting light and sounds has an LED and a speaker contained in a housing and electrically connected to a circuit board. When the ink stamp is pressed downward, the LED and the speaker will respectively give off light and sounds.

Abstract: An illuminating ball pen includes an ink cartridge received in a barrel, a joint pipe threadly engaged on a top end of the barrel, a top seat which is easily connected/disconnected with an upper end of the joint pipe, a lighting assembly provided in the top seat and with a lighting element protruded into a transparent globe a the top of the top seat, and a stamping seat secured in a lower end of the top seat. The lighting element of the ball pen will light or flash when a user is writing or stamping with the ball pen, or shaking the ball pen up and down.
