PROBLEM TO BE SOLVED: To provide a touch screen device in which a touch panel can be easily vibrated under acceleration large in a thickness direction and that can easily prevent cost and a thickness dimension from increasing.SOLUTION: A touch screen device includes: a motor 7 that is attached to a movable chassis 5 holding a touch panel 6 disposed on a front surface side of a display panel 30, in order to vibrate the touch panel 6 in a thickness direction; a rotor 8 that is fixed to a motor shaft 7a and a driven rotor 9 that engages with the rotor 8; a cam mechanism that converts rotation drive force of the motor 7 into drive force in a thrust direction and transmits the force to the movable chassis 5; and plate springs 4 that elastically energize the touch panel 6 moved by the cam mechanism in such a direction as to return the touch panel to the original position. The cam mechanism includes: two wave cam parts 20 provided to a fixed chassis 2 and each having a cam surface formed with continuous waveform-shaped irregularities along a circumference; and cam engagement parts 8a and 9a provided at shaft end portions of the rotors 8 and 9 and each contacting with each cam surface 20a in a sliding manner. |
