Patent ID: 7884971

Claim:
A multiplied pulse generation device comprising: a detection signal output unit that outputs a detection signal every time a driven object is driven by a specific amount; an actual cycle measurement unit that measures an actual cycle indicating a time interval between the detection signal and a previous detection signal every time the detection signal is outputted from the detection signal output unit; an estimation unit that estimates an estimated cycle indicating a time interval until output of a next detection signal from the detection signal output unit based on at least past two actual cycles every time the detection signal is outputted from the detection signal output unit, the at least past two actual cycles including the actual cycle measured by the actual cycle measurement unit as a result of output of the detection signal; and a multiplied pulse generation unit that sequentially generates a multiplied pulse obtained by multiplying the detection signal outputted, by a predetermined multiplication factor, every time the detection signal is outputted from the detection signal output unit, and that sequentially generates the multiplied pulse 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 measured by the actual cycle measurement unit to the estimated cycle estimated by the estimation unit every time the detection signal is outputted from the detection signal output unit.
