The light sensing unit 30 is installed on the lower end of the rotating body 55 to correspond to the light emitting unit 25 to detect light from the light emitting unit 25, and the rotation speed control mode is set. When the rotational speed is designated by the control function setting unit 20, the rotation corresponding to the rotational speed The microcomputer 35 for controlling the rotation operation of the 55 to be performed, the data storage unit 45 in which the rotation speed setting data is stored in advance, and the rotation under the control of the microcomputer 35 when the rotation speed control mode is set. A display signal processing unit 60 for processing the speed setting data and a display unit 65 for displaying a signal from the display signal processing unit 60 as a selection menu, wherein the rotation speed control set in the control function setting unit is performed. In this mode, the rotation speed of the rotating body rotates clockwise from counterclockwise or counterclockwise to clockwise can be set while the user views the selection menu for setting the rotating speed displayed on the display. Therefore, there is an effect that the user can select a wide range of the speed of the rotational speed.
