Description

I

. The firing of ognosigs to devices for the interaction of "enoBeKa-one paropa with a computer, in particular, to input / output devices of information made using a CRT.

A device for editing information on the SLT screen, containing a control block, is connected to a step-by-step movement of the marker and a marker position counter with the familiarity number IJ.

The closest in technical essence to the rented device is a device for editing information on a CRT screen, containing sequentially connected keys; / handles for moving the marker, a marker position counter associated with the AND element group, a marker position comparison unit and a control unit connected to the group elements And, video block in alphanumeric keyboard G2 | .

However, such devices do not provide automated output of markers.

It is familiar with the operator, taking into account one of the index marks displayed on the screen, and requires considerable time for the marker to be output.

The purpose of the invention is to increase the speed of the display and expand the area of the implanted device. This goal is achieved by the fact that a code character analysis block, a coincidence block V, a code character code comparison block associated with an alphanumeric keypad, a match block and a control block, a code sign analysis block are connected to the proposed device; block match - to the alphanumeric keypad and a group of elements I.

The drawing shows a block diagram of the device.

Claims (2)

The device contains a control unit 1, an alphanumeric keyboard 2, a keyboard for moving the marker 3, a counter for the positions of the marker 4, a block comparing the positions of the marker 5, a group of elements I. 6, a symbol comparison block 7, a match block 8, a code feature analysis block 9, and a video block 1O. The device works in the following way. The Control Unit 1 in a cyclical order makes reference to the familiar screen of the video block 1O to regenerate the image, placing the familiarity number codes on the first output, and the character codes corresponding to the circulating familiarity numbers on the second output. At the same time, at the inputs of the marker position comparison unit 5 there is a marker position code (from the marker position marker 4) and familiarity number code. (From the first output and control unit 1) At the moment these codes coincide, the output of block 5 is a signal to control unit 1. According to this control unit, control unit 1 generates a marker editing and displaying signal transmitted from the second output of this block to video block 10. With this signal, the iO video block displays a marker on its screen, and the place of the marker will coincide with the code in the counter ozitsii marker. 4. Keyboard of moving the marker 3 when pressing the keys produces increment signals that changes the code in the counter of positions of the marker 4 by one and accordingly changes the position of the marker on the screen of the video block Y. The alphanumeric keyboard 2 generates a code signal at the information output Coming out of the symbol and transmits it to the input of control unit 1. With this signal, control unit 1 generates and transmits to video block 10 a signal to display the corresponding symbol in the places indicated by a marker. Thus, the information on the screen of the video block 10 is edited (set) in the places sequentially designated by a marker. The information displayed on the screen contains index characters and a code to indicate the groups of characters to be edited. At the first input of the block comparison of the Kodo characters. The character code from the alpha-1I (} keypad 2, corresponding to the key pressed is received, the second input of this block is sequentially received by the codes of displayed characters from the second output of the control unit 1. the first input of the coincidence unit 8, the second input of which receives a signal from the control input of the alphanumeric keyboard 2, the third - the signal from the third output of the control unit 1 through the code feature analysis unit 9. If three signals coincide, the unit coincidence 8 generates a signal and transmits it to the control input of a group of elements And 6, which transmits the code of the familiarity number from the first output of control unit 1 to the information input of counter 4o positions by this signal. As a result, control unit 1 generates a signal marker on the familiarity, indicated by the index symbol corresponding to the symbol selected on the alphanumeric keyboard 2. Thus (the proposed device provides automated output of the marker on the sign a comest selected according to the index symbol displayed on the screen, which results in a reduction in the marker's withdrawal time and a wider area of application of the device. Claims. A device for editing information on a CRT screen, comprising successively connected marker movement keyboards, a marker position counter associated with the AND element group, a marker position comparison unit and a control unit connected to the AND group, a video block and an alphanumeric keyboard, characterized in that, in order to improve speed and expand the field of application of the device, a serially connected code analysis analysis, a coincidence unit and a code comparison unit are introduced into it s associated with an alphanumeric keyboard, a match box and a control box; the code feature analysis unit is connected to the control unit, the coincidence unit is connected to an alphanumeric keyboard and a group of elements I.
