whose 67, the first 68 and the second 69 UJ equipment and the element 70 I.

In the initial state (the surface of the tablet 65 is not pressed) there is no electrical contact between the two layers P1IN 66 of the plane JETA 65, therefore the current through the buses 66 does not flow and the second outputs of the keys 67 have the levels "O. In this case, at the outputs of the pythors 68 and 69 and at the output of the element And 70 there are also levels “O, which go to the first 71, second 72, third 73 outputs of block I. If the operator presses a plan 65 at some point on the surface, The closure of the corresponding busbars 66 of the first and second layers closes, for example, k-66 in the layer along the X coordinate and dip 66 in the layer along the Y coordinate.

tl | ui power on all elements / k: 1 | These devices are set to the initial state (the scheme of setting the initial state to a member of the drawing is not shown) and 5 pulses are triggered by the} | erato. In this state, the sg will be distributed until the appearance of one on the third output of block 1 code- 01 argina, meaning the coordinate of the THhix H1IN 6 () n) and pressing the working iioiiCjixHocTb nlanpteta 65. Formed) 1 by 1 coding the codes of the coordinates of the record 1) | wak) rc into the first 3 and second 4 formers of different coordinates; 1inat and trai.i counters 55 of the first and second formers 13, 14 of the coordinate codes of the marker, as pa inputs of these units signaling the resolution from the second output of the reset trigger 15.

11 ov1 on the third output of coding block 1, the signal is fed to the input of block 2, specifying operating modes, where the passage through the first element 16, the first element 11/1 and 21 and the first delay element 23 performs the transfer of the second trigger 25 to the next condition. After that, trigger 15 is cocked, thereby recording the coordinate codes in the generator 13, 14 of the coordinate coordinate codes in the subsequent work cycles. This ensures that the conditional origin of the coordinates is fixed and the device is switched to the exact reference mode.

During further operation of the device, only the coordinates of the coordinates relative to the fixed origin will be determined.

Triggering the trigger 15 in the presence of a signal at the third output of coding block 1 results in the appearance of a signal at the third output of block 2, specifying operating modes, as a result of which the pulse counter 6, the first and second adders 7, 8 relative coordinate increments are reset and recording is allowed.

If there is still a signal at the third output of coding block 1 (at least two coordinate buses 66 of tablet 65 are closed), the device operates in manual control mode. Using the current codes of the exact coordinates of the marker, the formers 3, 4 determine the increments of the coordinates with respect to the previous calculation step, which are added to their characters with the contents of the adders 7, 8 relative coordinate increments and with the contents of the first accumulating adders 57 of the formers 13, 14 after the occurrence of the signal input to the four outputs of the formers 3, 4. The first and second keys 11,12 at the same time commute the inputs of the formers 13, 14 with the second outputs of the formers 3, 4 intended for transmitting the coordinate increment characters nat In the first cycle of operation of the formers 3, 4, the relative coordinate increments, the input signal to their third output is not output, which is necessary for fixing the new conditional coordinate origin in exact mode when opening and re-closing the coordinate lines 66 of the tablet 65.

In the manual mode of operation, signals from the first or second outputs of the trigger 25 of the block 2 specifying operating modes, passing through the first 16 or second 17 elements AND, respectively, the OR element 21, the delay element 23, arrive at its first input and transfer from one state to another. As a result, the current coordinate codes are again overwritten from the coding unit 1 to the formers 3, 4 relative coordinate increments and compared with the previously fixed ones. The process is repeated for as long as at least some pair of coordinate pieces 66 of the plate 65 remain closed. The increments will have a non-zero value in the event of a change in the state of the coding matrix (a change in the position of pressing on the working surface of the tablet 65).

When the coordinate zones 66 are opened, when there is no signal at the third output of coding block 1, the device switches

0

It is in automatic mode. The signal, which appears at the third input of the trigger 5, sets it to its original state. At the third output of block 2 of setting the operating modes, there is no write enable signal in the counter 6 pulses, the first and second adders 7, 8 are relative coordinate increments. In the pulse counter 6, the time code is fixed during which the working surface of the coding unit 1 was pressed, and in adders 7, 8 relative coordinate increments, the total coordinate increments during this time.

At the fourth exit of the block 2 tasks

5 operation modes with a delay introduced by delay element 24, a signal appears enabling the drivers 9, 10 and translating the keys 11, 12 to switch the inputs of the drivers 13. 14 with the second outputs of adders 7, 8, from which signs of total increments are removed coordinates to specify the direction of increasing the content of the formers 13, 14 (increasing or decreasing).

When a signal is applied to the fourth input

5 the generator 9 (10) of the increment of coordinates is reset the first 48 and second 49 counters and performs the operations of dividing the contents of the pulse counter 6 by the contents of the adder 7 (8) by subtracting the second from the first with the second combination combiner 33. The result is equal to the average the duration of the individual pulses is recorded in the first counter 48. After that, the pulse of the generator of the 5 pulses connected to the third

5 to the input of the imaging unit 9 (10), to the counter 49, the contents of which are compared with the contents of the counter 48 by the arithmetic logic unit 50. If the contents of the counter 49 are equal to or greater than the contents of the counter 48, the block 50 produces pulses that reset the counter 49, after 4 increasing the content of counter 49 is repeated again. From the former 9 (10), which is the output of the block 50, to the counting inputs of the former 13, 14 will be

thus, the pulses are supplied, the frequency of which is determined by the contents of the counter 6 of pulses and adders 7, 8, defined by the direction and speed of the line drawn by the operator on the working surface of the tablet 65.

0 If in the automatic mode of the marker operation on the screen of the display device, press on the surface of the tablet 65, the device will enter the manual control mode and will function according to the algorithm described above.

5 To fix the current coordinates of the marker, use the Combine button (not shown), blocking the operation of the first 3 and second 4 drivers, the score is 0

Chika 6 pulses, the first 9 and second 10 formers. The resetting of the circuit to its initial state is performed by the button "Reset (not shown).

The proposed device provides a higher speed, since the device additionally provides an automatic marker movement mode, which is accessed upon opening the coordinate tins 66 of the tablet 65. In this mode of operation, the output coordinate codes of the marker are automatically changed by analyzing the direction and speed of the marker fixed on the previous, we restrict the stage of work.
