Abstract
This disclosure concerns a velocity detector comprises a memory storing preset tentative angles and a trigonometric function value corresponding to each of the preset tentative angles; a first register storing a first coordinate (x, y) of a body; a second register storing a second actual coordinate (x, y) of the body; a first calculator calculating a first calculational coordinate represented by an addition or a subtraction between xand a result of shifting a figure of ybased on the trigonometric function value; a second calculator calculating a second calculation coordinate represented by the addition or the subtraction between yand a result of shifting a figure of xbased on the trigonometric function value, wherein the first and the second calculators calculate the first and second calculational coordinates respectively so that the first actual coordinate (x, y) and the second actual coordinate (x, y) are closer to each other.
