Abstract:
1. A displacement sensor for repeatedly performing a detection process including projecting light onto an object and receiving light reflected from the object and a measurement process that measures an amount of displacement of the object based on the reception of the reflected light, and determines a moving average calculation of data of the measured amount, for outputting detection data based on an average value obtained by the moving average calculation, comprising: a register that registers a number of pieces of data of the moving average calculation; an input that inputs a parameter representing conditions related to a response time of the displacement sensor and a parameter representing conditions related to accuracy of the detection data; and a teaching mode processor that executes a teaching mode in which the number of pieces of data of the moving average calculation is registered with the register, wherein the teaching mode processor includes:
