Patent ID: 8196924

Claim:
A drive control method for a processing machine which includes, first drive means, first driven means driven by the first drive means, second driven means rotationally driven by the first drive means via the first driven means, a first rotating body provided with a first holding portion for holding a member to be processed, and rotationally driven by the second driven means, and a second rotating body provided with a second holding portion for receiving the member to be processed, from the first holding portion of the first rotating body, the drive control method comprising: providing second drive means for rotationally driving the second rotating body; indicating means for indicating a rotational phase and a rotational speed which the first rotating body should have; first rotational phase detecting means for detecting a rotational phase of the first drive means; and second rotational phase detecting means for detecting a rotational phase of the first rotating body; and controlling a rotational speed of the first drive means based on the rotational phase and the rotational speed, which the first rotating body should have, from the indicating means, the rotational phase of the first drive means from the first rotational phase detecting means, and the rotational phase of the first rotating body from the second rotational phase detecting means.
