PURPOSE:To perform complicated operations and enable various intelligent control by providing plural display bodies with driving parts respectively and individually controlling them. CONSTITUTION:At the center part of a base 1, a recessed part 3 is formed in the length direction of the base 1, and in the recessed part 3, plural rotary driving parts 4 are arranged in the lengthwise direction at specific intervals. Thin actuators, e.g. ultrasonic motors 5 are used for the rotary driving parts 4. In the base 1, a power source part 10 and a control circuit 11 as an intelligent control part are stored. The display bodies 7 are provided with the rotary driving parts 4 independently of one another, so the respective ultrasonic motors 5 can be driven at the same time the control of the control circuit 11, and also driven individually. The control circuit 11 can easily be designed according to various purposes of use and various intelligent operations can be performed. |
