この発明は表面形状を測定して一枚の記録紙上
に三次元に記録する装置に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus that measures a surface shape and records it three-dimensionally on a sheet of recording paper.

…の測定を行なう。 In Fig. 1, while moving the surface of the target object 1 along the dotted line 2, that is, in the A generally known method is to shift the target object 1 by P in the Y direction and measure and record along dotted lines 3, 4, . . . . For this purpose, as shown in Fig. 2, a target object 1 is set on a table 5, a probe 7 is provided that contacts it from above, and the fulcrum 8 of the lever of the probe is moved in the X direction, that is, in the lateral direction. is moved by the rotation of the motor 6,
Trace above dotted line 2. Here, this amount of movement is defined as the amount of movement X. The table 5 on which the target object 1 is placed is movable by the rotation of the pulse motor 10 in a direction perpendicular to the moving direction X of the probe fulcrum 8, and the amount of movement is defined as the amount of movement Y. When the measurement record of line 2 in Figure 1 is finished,
Move Y by the set pitch P and line 3, 4,
Measure...
ここで記録器１１の横方向をｘ、縦方向をｙと

把握するのには手数と時間を要し、かつ精度も確
保できない欠点があつた。 Here, if the horizontal direction of the recorder 11 is x and the vertical direction is y, then the horizontal displacement amount X of the probe 7 is amplified by an appropriately set magnification and becomes the x input of the recorder.
Z and Y pass through the adder and enter y, and the lines 2, 3,
4. Record the surface shape at... Assuming that the measurement surface is a perfect plane, Z=0, and parallel lines separated by a pitch P are drawn on the paper. However, the curve as shown is due to a change in shape in the vertical direction from the parallel line, that is, a displacement in Z.
Therefore, the surface shape can be determined three-dimensionally from this figure. However, although this records the cross-sectional shape in the X direction continuously, it takes time and effort to accurately grasp the shape in the Y direction, and there is a drawback that accuracy cannot be ensured.

The purpose is to draw the cross-sectional shape of the surface in order to obtain curves 13, 14, and 15 as shown in FIG. First, the Y signal will be explained. In FIG. 2, when the movement amount Y of the target object 1 is commanded, a corresponding number of pulses is sent to the pulse motor 10, and the pulse motor performs a predetermined rotation,
The table moves. The pulse signal is then DA-converted, amplified to a specified magnification, and divided into two parts, one of which passes through the adder and is sent to one pole c2 of the switch C, and the other Directly enter the other pole c 1 of the switch, one of which is connected to the recorder y
This becomes the polar input.

When connected to pole b 1 , it becomes the x-pole input of the recorder, and when switched to the second pole b 2 , it becomes the other input of the adder,
(Z+X) is calculated, and the addition result becomes the input to the x pole of the recorder.
