Description

one

The present invention relates to the field of computer technology and data transmission for outputting information to a punched tape by means of an electromechanical perforator from computers and information transmission equipment via communication channels.

A device for controlling information is known, which contains a block of TDM, AND and OR logic circuits, a punch control block, a comparison block, an error signal and a new read signal generation unit.

However, in the known device, error detection does not take into account the nature of the errors, i.e., is the error caused by non-probing holes in a row or punching an extra hole, moreover, no errors are detected that are caused by the tape moving without sign punching.

In order to increase the perforation speed while improving the quality of the perforated tape in the proposed device, a re-read unit is connected to the output of the comparator when stopping the punched tape, the outputs of which are connected to the corresponding AND logic, and the input of the perforator control device is additionally connected to one input of the circuit unequalities having another input for the signals from the motion sensor perfolept, and an output connected to the corresponding input of the perforator control unit.

The drawing shows a block diagram of the proposed device.

The device contains a memory block 1, a driver circuit 2, logic circuits And 3-14, logic elements of the circuit OR 15-20, a punch control unit 21, a comparison unit 22, a signal generation unit 23

an error and a re-read signal comprising an electronic delay circuit 24, an electronic key 25 and a permanent memory device circuit 26; re-reading unit 27 without advancing the tape; comprising an inverter circuit 28 and an electronic switch 29; scheme 30 unequalities. When signals are received at the perforation, the input signals are memorized by memory block 1, and, depending on their code combination, the negative potential is not received on the corresponding "I. To the other inputs of the odd circuits "And 3, 5, 7, ..., 13, the negative potential is supplied from the circuit 27, and to the third input of the circuit" And 13 - from the inverter

28, re-read unit 27 without advancing punched tape. Further, the information signals through the OR 15-20 circuits are fed to the perforator control unit 21 and simultaneously to the comparison unit 22. With the arrival of the input clock to the input block

21, the perforator control gives a pulse to the electromagnet of the single turn actuator coupling (not shown in the drawing) and a sign is perforated. When a punch corresponding to the coding electromagnet (not shown in the drawing) is triggered, a signal is generated that enters block 22 and contains t, output, to which, respectively, negative potential is given when the hole is punched and the hole is broken.

If the perforation is performed without errors, then the signal from the output 31 of the comparator unit 22 is sent to the memory unit 1, where it erases the recorded information; The perforator is ready for perforation of the following code combination. With an aperture, the signal from the output 32 of the comparator unit 22 is supplied to the inverter circuit 28 and the electronic key 29 of the re-read unit 27 without advancing the punched tape. From the output of the inverter 28, the signal is fed to the inputs of the circuits "And 13 and 14, prohibiting the passage of a sync pulse to the punch control unit 21. From the output of the electronic key 29, the signal enters the paired inputs of the circuits AND 4-14 and through the circuits OR 15-19 to the control unit of the perforator. The mark is re-punched without moving the tape. In this way, errors caused by the non-piercing of the hole in the punched tape are eliminated.

When an extra hole is punched, the signal from the output 33 of the comparator 22 enters the persistent storage circuitry 26 and the electronic delay circuit 24. A permanent storage device generates a service signal in the received code on the line, indicating an error. From the outputs of the Permanent Memory Circuit 26, the signals through the OR 15-20 circuits enter the punch control unit 21. An error sign is punched in the received code on the next line after the erroneously perforated sign. From the output of the electronic control circuit 24, the signal through the key 25 is fed to the even circuits “AND 4-14. The information symbol la is re-punched into the next line after the error sign. In this way, the errors caused by the punching of the excess hole are eliminated. In order to detect errors caused by the advancement of the tape without a perforation of the sign, an unequal circuit 30 is used, one of the inputs of which receives a signal from the tape motion sensor (not shown in the drawing), and the other - sync pulses from memory block 1. the input signals do not match, the signal from the output of the unequal circuit 30 enters the perforator control unit 21, prohibiting further perforation.
