摘要： A dual pendulum display apparatus comprising a housing, a motor which is fixed to the housing and which has an output shaft, an output gear which is driven by the output shaft, which is mounted on the housing for rotation relative thereto about an output gear axis, and which has thereon a projection spaced from the output gear axis, a pivot arm mounted on the housing for pivotal movement relative thereto about a pivot arm axis spaced from the output gear axis, the pivot arm having therein a longitudinal slot receiving the projection for reciprocal sliding movement of the projection in the slot, such that rotation of the output gear and movement of the projection in the slot causes pendulum type motion of the pivot arm, the pivot arm having opposite first and second ends spaced from the pivot arm axis, first advertising material mounted on the first end of the pivotal arm, and second advertising material mounted on the second end of the pivot arm, such that the first advertising material and the second advertising material move back and forth in opposite directions in response to pendulum type movement of the pivot arm.
