Abstract
A touch screen device includes a motor attached to a movable chassis to support the touch panel, a rotor fixed to the motor shaft, a driven rotor meshing with the rotor, a cam mechanism that converts the rotational driving force of the motor into a driving force in the thrust direction and transmits the driving force to the movable chassis, and a leaf spring elastically urging the touch panel moved by the cam mechanism toward the original position. The cam mechanism includes two wave cam portions that each have a cam surface having a series of wave-like recesses and protrusions arranged along a circumference and, and cam engaging portions that are provided at the axial ends of the rotors and that are in sliding contact with the cam surfaces.
