The invention relates to computing and can be used as a computing unit 20 of a computer (in-depth manual) at the rate of Descriptive Geometry. The engineering of graphics to TCO when plotting plots specified in the space of points.

The aim of the invention is to enhance the functionality by making it possible to find the coordinates of a point defined in space .30

Figure 1 schematically shows the proposed device (without decorative krpak); figure 2 is the same, top view.

The device comprises a housing 1, on the supports 2 and 3 of which, by means of the third shaft 4, the running screws 5 and the driving shafts 6 and 7 are respectively mounted. On the screws 5 there are threaded nuts 8 bearing the first guide rail 9, and the shafts 6 and 7 are equipped with Q two gears moving along them Yu and two fixed wheels similar to wheel 11. On supports 2 screws 5, the second rail 12 is fixed, while both rail 9 and rail 12 are equipped with gear serres 13 and 14 respectively moving. On the sliders 13, the arrow indicators 15 and 16 are installed (for

setting the given numerical expressions along the OS and OZ axes), and on the left (according to the drawing) end of the strip 9 a similar arrow-pointer 17 is fixed for setting the numerical values along the OX axis.

For the purpose of free movement of the directional arrows 15, 16 and 17 in the cover of the housing 1, grooves 18, 19 and 20 are made with a graduated scale each. In addition, shafts 5-7 are equipped with

handwheels 21 and 22, 23 for their rotation.

The device works as follows.

For a given value of X, the driving knob 21 of the running screws 5 rotates until the arrow 17 on the bar 9 (Fig. 2) is set against a predetermined numerical value controlled by the scale along the groove 16. Thus, the coordinate of the point along the OX axis is set.

Then, by rotating the handle 22 of the drive shaft 6, the pointer 15 is moved along the groove 19 to the corresponding (specified) numerical value Y along the axis OS. In this way, the coordinates of the point are set along the OS axis. At the end, by turning the knob 23 of the shaft 7, the arrow 16 is moved to coincide with the specified numerical value of the scale along the axis OZ (demand).

Thus, by applying three variables at once to the input of the mechanism (X, Y, and Z), we obtain the true position of the point in space in accordance with the previously specified coordinates.
