Referring to Figures 5 and 6 will be described the operation of moving the electronic top in the horizontal direction of the present invention.

First, when the rotating mass 18 is rotated at a constant angular velocity by operating the power motor 14 of the present invention, the body 10 of the electron top stands up and rotates at a constant angular velocity.

Next, the shaft 24 of the auxiliary motor 22 is rotated in the opposite direction to the shaft 16 of the power motor 14 so that the relative speeds of the auxiliary motor 22 and the power motor 14 are substantially the same. In other words, the arrow points in a certain direction and remains almost stationary.

At this time, by operating the transmitter, the light receiving element 42 adjacent to the arrow of the pointer 26 receives and transmits it to the receiver 40, and operates the horizontal moving means 30 connected to the light receiving element 42. Then, as shown in Figure 5, the magnet means 36 of the horizontal moving means 30 is moved to the inside of the body (10).
