Abstract:
1. A signal generating device, adapted to be installed in a liquid ejecting apparatus which comprises a liquid ejector operable to eject liquid and a carriage operable to carry the liquid ejector, the signal generating device comprising: a first generator, operable to generate first pulse signals at first intervals corresponding to a velocity of the carriage which moves with a variable acceleration; an estimator, operable to estimate a second interval which is an interval of the first pulse signals which will be generated by the first generator based on a variation of an acceleration of the carriage as a second interval; a timing signal generator, operable to generate a timing signal determining a timing at which the liquid is ejected from the liquid ejector, based on the second interval: a first divider, operable to divide the second interval into a plurality of third intervals, each of which is a time period to which a first correction is applied based on the variation of the acceleration; a second generator, operable to generate second pulse signals at the third intervals, wherein the timing signal generator is operable to generate the timing signal based on the second pulse signals; a second divider, operable to divide the second interval into a plurality of fourth intervals, each of which is a time period to which second correction is applied based on the variation of the acceleration; a fourth generator, operable to generate third pulse signals at the fourth intervals; a storage, operable to store a delay value indicative of a delayed amount of the second pulse signals; a delay provider, operable to count a number of the third pulse signals, and operable to delay each of the second pulse signals for a time period that the number of the third pulse signals counted by the delay provider is reached to the delay value.
