Abstract
A surface texture measuring instrument includes a force sensor (), an actuator () and a detector (). The surface texture measuring instrument further includes: a scanning controller () that collects a detection signal from the force sensor () and drives the actuator such that the detecting signal coincides with a target measurement value; a touch signal generator () that generates a touch signal when the detection signal from the force sensor () coincides with the target measurement value; and a measurement value collecting unit () that collects a measurement value from a counter () at a predetermined time interval in a state where a fluctuation range of the detection signal from the force sensor () is within a preset range when a scanning controller is in operation, the latch counter () collecting a measurement value from a latch counter () each time the touch signal is generated in a state where the detection signal from the force sensor () oscillates and an amplitude exceeds the preset range.
