To enable an electronic device to display a character with unexpectedness and make the character perform a fantastic motion to increase interest by equipping a rotating means to give rotation force to a virtual life body and controlling the rotation of the virtual life body based on the given rotation force and freely settable parameters.

Key switches SW1-SW3 are operated to set this electronic device in a starting mode to start movement of an electronic top. When a holding part 5a is held to pull out a band 5, through-holes 6a-6c formed on the band 5 at a prescribed pitch are orderly detected by a photocoupler to calculate the moving speed of the band 5 by a built-in controller and determine the rotation direction of the electronic top based on the detection timing, and, further, the initial rotation speed of the electronic top is set. Based on the initial rotation speed and various parameters, the rotation of the rotation top is controlled and its motion pattern is displayed on a liquid crystal display. A rotor with a gear part to be engaged with a gear part 8 of the band 5 is rotated to obtain feeling of rotating a small top.
