(54) KEYBOARD FOR PROCESSING AND REGISTRATION OF INFORMATION

a storage unit 8, a recording unit 9 and a display block 10,

A keyboard device for recording information works as follows. The data of the primary document in the decimal code is typed on the keyboard 1 and through the encryption {C 2, which converts the decimal numbers into the binary code, are entered into the shift register 4 until it is completely executed. The shift register temporarily stores the numeric information of one line of the primary document. This information is displayed on the display of the display unit 10, the operator controls its accuracy, with the data of the primary document.

The signal from the control unit 3, which coordinates the computational processes and the exchange of information between the various nodes of the device, is entered sequentially in the buffer storing unit 8, starting with the lower order, all the information recorded in the shift register 4. This information is stored. S1TSYA in the buffer storage unit 8 until the end of processing the primary document.

At the same time, the numerical I13 formation, which characterizes the launch of products into production, is entered from the shift register 4 into the register of the number 5, where it is kept until the end of information processing. Information disrupting the output of finished products and rejects also comes from shift register 4 to summation block 6 and the branch is in it. At the same time, the control unit 3 provides the connection of the shift register 4 at the corresponding time intervals to one of the nodes of the 5-register number 5 or the summation block 6. After processing the last line of the primary document, the information from the number 5 register and the summing block 6 comes in the form binary-decimal numbers to the inputs of the block of comparison 7. In the case of equality of numeric

block values, compare. generates a signal arriving at the control unit 3 which, in turn, generates a sequence of signals permitting the registration unit 9 to read all the numerical information recorded in the buffer storage unit 8. In case of discrepancy of the numerical values recorded in the register 5 numbers and

the summing unit 6, the comparison unit 7 generates a signal by means of which an error signal is generated in the control unit 3 indicating that the error was made either by the operator during the input of the primary document data

the device, or an error exists in the source document, or the device itself makes an error (for example, a code failure).
