ABSTRACT:
A drive controlling method for a carriage which permits absorbing of a vibration caused by cogging, eccentricity of a motor pulley, or the like, without providing a vibration absorbing mechanism; and an electronic apparatus and a liquid ejecting apparatus provided with a carriage controlled by this controlling method. The drive controlling method includes: detecting a first period, a first phase, and a first amplitude of a vibration generated in the carriage; and controlling a velocity of the carriage on the basis of a signal having a second period and a second amplitude each of which is the same as the first period and the first amplitude, and having a second phase shifted by a predetermined value from the first phase.
