Abstract
In a multiplied pulse generation device, a detection signal is outputted every time a driven object is driven by a specific amount. An actual cycle indicating a time interval between the detection signal and a previous detection signal is measured. An estimated cycle is estimated based on at least past two actual cycles including the actual cycle measured. A multiplied pulse is sequentially generated in such a manner that a multiplied cycle indicating a time interval per which the multiplied pulse is generated is sequentially changed according to an amount of change from the actual cycle to the estimated cycle.
