Description

(54) END TELEGRAPHIC DEVICE

one

The invention relates to communication technology and can be used as a terminal telegraph device.

A known telegraph terminal device contains a block of diameters, a registration unit, a telegraph node and a serially connected keyboard unit and a control unit connected to the telegraph node, the memory unit and the registration unit, to the corresponding input of which the output of memory unit 1 is connected.

However, such a device has a low accuracy of the processed information.

The purpose of the invention is to increase the reliability of the processed information.

For this purpose, an indicator is inserted into the terminal telegraph unit containing a memory unit, a recording unit, a telegraph node and a serially connected keyboard unit and a control unit connected to the telegraph node, the memory unit and the recording unit, to the corresponding input of which is connected to the memory unit. and the first switch connected in series, the information exchange unit and the second switch, the outputs of which are connected to the inputs of the memory unit and the telegraph node, the output of the latter is connected to the input of the first com utatora to its second input connected to a second output:

keyboard unit, and the control input and the second output of the first switch are connected respectively to. The first additional output of the control unit and the second input of the second switch, to the control input of which the second additional output of the control unit is connected, which is connected to the information exchange unit, the second output of which is connected to the indicator input.

The drawing shows the structural electrical circuit of the device.

The device contains a memory unit 1, a registration unit 2, a telegraph node 3, a keyboard unit 4, a control unit 5, an indicator 6, switches 7 and 8, an exchange unit 9

information.

The terminal telegraph device operates as follows.

Claims (1)

With the introduction of telegraphic conversations (dialogue), the information of the keyboard unit 4 is fed to the input of the switch 7, and upon a command from block 5, information from the output of the switch 7 is fed to the input of block 9, in which information is accumulated in an amount sufficient to control. The information, as it arrives at block 9, is fed to indicator 6, which provides a parallel visual control of each character of the string directly in the process of its formation. If necessary, any character of the information line generated in block 9 can be changed by the command that is sent from block keyboard 4 to block 5, and then goes to block 9, and in dialogue mode switch 7 provides connection to block 9 of information arriving as keyboard unit 4, and from the communication channel through the telegraph node 3, the information generated in unit 9 is received from the output of unit 9 to the input of the switch 8, from the outputs of which the command 9 comes from the keyboard unit 4 to the input of block 5 and to block 9; on signal, p The unit arrives at its control input from unit 5, is fed to unit 1 and to the input of the telegraph node 3, from where it enters either the communication channel or the intermediate amplifier in the data preparation mode. The output of information from block 1 to the spreadsheet is made by the signal from block 5. From the output of block 1, information is sent to block 2, which is controlled by signals from block 5. As a block 2 of the registration, a facsimile can be used device, or another document device that prints all the characters of the information line with high speed. The operation of the terminal telegraph device when receiving information from the telegraph node 3 at a relatively high speed and in an unattended mode differs from the fact that the switch 7 does not receive information from the keyboard unit 4, but from the output of the telegraph node 3. In addition, from the output of the switch 7 information can be received either at the input of block 9 or at the input of switch 8, which is achieved by submitting a control command from the output of keyboard unit 4 to the input of block 5 and further respectively at switches 7 and 8. e device ensures high accuracy of the processed information. The end telegraph device comprising a memory unit, a recording unit, a telegraph unit and a serially connected keyboard unit and a control unit connected to the telegraph unit, the memory unit and the recording unit, to the corresponding input of which is connected the output of the memory unit, distinguished by that, in order to increase the reliability of the processed information, an indicator and a series-connected First Switch, an information exchange unit and a second Switch are introduced, the outputs of which are connected The inputs of the memory unit and the telegraph node, the output of the latter is connected to the input of the first switch, to the second input of which the second output of the keyboard unit is connected, and the control input and the second output of the first switch are connected respectively to the first additional output of the control unit and the second input of the second switch, to the control input of which a second auxiliary output of the control unit is connected, which is connected to the information exchange unit whose second output is connected to the indicator input.
