To provide a control method for a carrier driving mechanism which suppresses the speed fluctuation by pulsation at constant speed traveling, while executing the quick start up by shortening the start up region, in a control method for a carrier driving mechanism.

In the above control method for a carrier driving mechanism, it is shifted to constant speed traveling, when the acceleration generated in the pulsating carrier in its start up region becomes, minimum. A control program for prescribing the procedure of the control of the above carrier driving mechanism is stored in a computer-readable recording medium.
