PROBLEM TO BE SOLVED: To reliably detect an approximately stationary state wherein the rotation of a rotary table can be regarded to be almost completed in an injection molding machine using the rotary table and to make the next process such as an ejection process be carried out without trouble even when the movement of the process is started immediately after the judgement of rotation completion. SOLUTION: A measured pulse value by the output of an encoder is monitored. When the measured pulse value, after entering a set prescribed vibration width range indicating a damped vibration domain before the completion of table rotation, maintains a value within a set prescribed rotation limit judgement width range where the width is set to be smaller than that in the prescribed vibration width range continuously for a prescribed time, it is judged that the rotation of the rotary table is stopped, and the movement of the next process is started.
