An auto equality and alternately controlling apparatus for an equipment composed of main and auxiliary units is provided to improve an eccentric driving method of the equipment composed of the main and auxiliary units into an auto equality driving method. An auto equality and alternately controlling apparatus for equipment composed of main and auxiliary units includes an integrating timer(T1,T2), an alternate rachet relay, and an auxiliary relay. The integrating timer(T1,T2) integrates the driving time of the main unit which currently drives and generates an output signal which automatically drives the auxiliary unit when a predetermined time passes. The alternate rachet relay converts the currently driving main unit to the auxiliary unit by being controlled based on the output signal which is generated from the integrating timer(T1,T2). The auxiliary relay remembers the output signal which is generated from the integrating timer(T1,T2), and prevents the currently driving unit from being sudden stopped by transmitting an alternate order according to the output signal to the alternate rachet relay after the stroke of the currently driving unit is finished.
