Description

one

The invention relates to the field of automation and improving equipment and can be used to enter information into the digital computer and data transmission equipment,

Known devices for entering information 1, 2.

One of the known data entry devices comprises a read unit associated with the transport mechanism, and a control unit connected thereto and a code converter Cl},

The closest technical solution to the present invention is an information input device comprising an information reading unit and a punched card presence sensor associated with a transport mechanism, a control unit connected to a code converter connected to an information reader unit to a transport mechanism and punched card sensor {21

A disadvantage of the known devices for entering information is the impossibility of entering information with codes containing register features, which limits the scope of application of known devices

The aim of the invention is to expand the field of application of the information input device.

This goal is achieved by the fact that the proposed device contains a unit of a register feature, the input of which is connected to the output of the information reading unit, and the output to the control unit.

FIG. 1 is a block diagram of a device for inputting information; FIG. 2 is a block diagram of a register feature allocation unit.

The device for entering information contains a reading unit. Information module 1 and a sensor for the presence of punch cards 2 connected with the transport mechanism 3, a control unit 4 connected by a code converter 5 and a block for registering a sign 6.

Claims (2)

Unit 6 contains a code analyzer 7 connected to a switch 8, a switch 9 and a comparison circuit 10 connected to a register fixation circuit with; 11, the control unit 4 is connected to the sensor 2 and the transport mechanism 3, and the unit 1 to the inputs of the converter code 5 and the allocation unit b, which are interconnected. The device works as follows. When reading information from a punched card and then converting it to a code with register features, switch 8 in the block of the register feature is set to position A. A punched card is installed in the path of the transport mechanism 3. Sensor 2 detects the presence of a punched card and its signal through the control unit 4 activates a transport mechanism that moves the punched card. According to the first information column of the punched card perceived by the information reading unit 1, its code enters converter 2 of code 5. As a result, a signal is generated in it which, through control unit 4, turns on transport mechanism 3. At the same time, the code from unit 1 is fed to the code analyzer 7 of block 6, generating a register indication indicating to which register the given information byte belongs, which is gated by the first signal from the switch 9 by the external control signal. This signal is the first of a series of signals that are used to input information to the consumer. This register feature enters the code converter 5 and is fixed at its output, as well as in fixing circuit 11, and is compared with the same register sign selected in the code analyzer 7, in comparison circuit 10, from the output of which the signal confirming the identity of these signals comes into control unit 4. At the same time, the rest of the code belonging to this byte of information is output from code converter 5 and the punched card is moved until it receives the next column. During subsequent read cycles, the register misalignment entered in circuit 11 is maintained as long as the next punch card columns contain information related to this register. When the device is used to enter information from punched cards with codes that do not contain a register sign, switch 8 is block in the register list set to position b. In this case, the code analyzer 7, the switch 9 and the comparison circuit 10 are blocked and information is entered and entered into the consumer without generating a register code. Claims An information input device comprising an information reading unit and a punched card availability sensor associated with a TpaHcnopTi mechanism, a control unit connected to a code converter connected to an information reading unit, to a transport mechanism and a punched card sensor characterized in that expanding the field of application of the device, it contains a block of register register feature, the input of which is connected to the output of the information reading unit, and the output - to the control unit.
