When a straight line perpendicular to is l, the plate surface is approximately perpendicular to the optical axis and slightly inclined to the straight line l, and one end of the plate surface is on the straight line l,
a scale plate whose other end is separated from the straight line l to the opposite side of the first optical system and is displaced in the direction of the straight line l by the object to be measured; and a position on the scale plate where the light is incident;
a scale displayed at a predetermined pitch along the longitudinal direction of the scale plate; a second optical system that makes the light reflected by the scale plate enter the light receiving element; and counting the number of pulses output from the light receiving element. and a displacement detection circuit that detects the amount of displacement of the scale plate, and a displacement detection circuit that detects the direction of displacement of the scale plate depending on whether the amplitude of the pulse output from the light receiving element is increasing or decreasing. A displacement detection device, comprising: a displacement direction detection circuit for detecting displacement direction.
