Abstract
On the basis of an encoder output pulse generated by useing a linear encoder film provided along a moving path of a carriage, ink ejection timing is determined. Then, the ink ejection timing is set at a timing derived by dividing a period of the output pulse by three, and the pulse period to be divided is the immediately preceding pulse period. By this, even with open loop control of driving of a carriage motor, high precision ejecting position control can be performed.
