PROBLEM TO BE SOLVED: To provide a shape-measuring apparatus filling for both the need to search for an object measurement before succeeding in shape recognition, and the need to measure the shape of the object, after succeeding in shape recognition. SOLUTION: This instrument is equipped with a light source, a light-scanning means for scanning with a light beam in the direction of a first axis, a photoelectric transducing means for transducing the energy of received light into an electrical signal, corresponding to the position and intensity of the light, a focusing means for focusing laser light emitting from the source and reflected by a surface of the object to a light spot on the transducing means, a focusing position calculating means, for calculating at what position of the transducing mean the spot is focused from the signal outputted from the transducing means, and a distance calculating means for calculating the distance to the object from the output of the position calculating means. IT is further equipped with a shape recognizing means for collecting distance outputs of the distance calculating means for a fixed period of time, to recognize the shape of the object from the colleted outputs, a waveform-generating means for changing a generated waveform, when the recognizing means succeeds in shape recognition, and a driving means for driving the scanning means, based on the output of the generating means.
