ABSTRACT:
The invention relates to the driving mechanism of multi-action doll. The driving mechanism comprises an eccentric roller, a cross-shaped driving component and several driving gears. The cross-shaped driving component has a rectangular hole which accommodates the eccentric roller which moves the cross-shaped driving component back and forth in a linear direction when the roller rotates in the hole. The cross-shaped driving component has racks that mesh with and rotate the driving gears when the driving component is moved by the eccentric roller. Rotation of the gears also rotates shafts on the gears which convey motion to selected portions of a moveable doll.
