PROBLEM TO BE SOLVED: To improve the stage effect by an amplitude-drive, while increasing its working efficiency. SOLUTION: When a suspended stage setting and a floor mechanism are driven to their desired positions as being controlled according to a speed pattern specified, through a time axis which is set by a seed-pattern setting means 1 and to an amplitude-distance set by an amplitude-distance setting means 2, driving them to their next desired positions by reversing the amplitude- distance, this operation is repeated from the start of the drive of the stage apparatus during the time set by a drive-continuing-time setting means 12 to complete the drive by outputting a stopping command to a control-appliance driving means 7, when a drive completing time is reached. |
