Abstract
PURPOSE: To facilitate the variable adjustment for the totational cycle, the rotational frequency, the pitch and others in the fine step by using the program logic device.
CONSTITUTION: Plural units of push-buttons are provided to input part IA of the indication signal in order to give the individual designation to several rotational modes which are decided previously at the turntable. Thus the signal sent from IA is applied to program logic device PLA consisting of, for example, the microcomputer. And PLA supplies the cyclic signal to PLL so that the truntable may turn in the rotational mode which is set to IA of the designation signal. At the same time, the display signal is applied to display unit DP.
