(54) DEVICE FOR REGISTRATION OF INFORMATION

I

The invention relates to information and computing technology and can be used to display information on electrically sensitive media.

According to the main author. St. No. 591882, a device for recording information is known, comprising a tape mechanism connected via a paper speed sensor to a time counter and read signal generator and print time, a decoder connected via a memory unit to a print unit, a comparison block and an information request trigger.

A disadvantage of the known device for recording information is the insufficient speed and uneven recording density of information on the carrier, which is due to the fact that at low speed of movement of the carrier, the current time code will be greater than the values of the course of autonomous time and there will be a pause in reception of information for registration, high speeds of movement of the carrier may occur on the carrier of the pro. whites caused by the lack of

right moment of information, i.e. there will be a violation of the uniformity of the recording density.

In order to increase the speed of the device for registering information, the proposed device contains a write address counter, a setpoint speed drive, a register and an adder, the first input of which is connected to one of the address inputs of the memory unit and the output of the write address counter whose input is connected to the decoder and register inputs the output of which is connected to the second input of the adder, the third input of which is connected to another address input of the memory unit and to the time counter, and the output of the adder through the task of setting the carrier speed oedinen zhnym with tape transport mechanism and the input of the comparison unit.

The drawing is a block diagram of the proposed device.

It contains the decoder 1; memory block 2; a printing unit 3 connected to a tape machine by a mechanism .4; equipped with a speed sensor 5; counter 6 time; shaper 7 signalov print time; shaper 8 read signals of selected tires; block 9 compare:; 368 cyMivtaiop 10; counting address 11 write address; register 17; carrier speed setting unit 13 and trigger 14. Inputs de B1 1, counter 11 of write address, register 12 and comparison block 9 are combined and are device input, Decoder 1 is connected to memory block 2 connected to output of counter 11 of write address, adder 10 The driver of the time signals for printing and reading the selected tires, the inputs of which are connected to the adder 10, the comparison unit 9 and the time counter 6 connected to the speed sensor 5. The carrier speed setting unit 13 is connected with the tape mechanism 4, the adder 10 and the comparison unit 9 connected to the trigger 14. The device for recording information works as follows. The information sent to the input of the device, after the decoder 1, is recorded in memory block 2 at the address generated by the AND write address counter. At the same time, the address code of this counter is fed to the input of the adder 10 and further to the unit 13 specifying the speed of the carrier. After the sensitivity threshold of this block is exceeded, the tape-driving mechanism 4 is turned on and the carrier begins to move, leading to the appearance of signals from the speed sensor 5 and their counting with the help of a speed counter 6. The value of the code taken from the speed counter serves to set the address by which the information from memory block 2 is used. When the speed counter code 6 changes, the tire read signal generator 8 and print time signal generator 7, which control the transfer of information from memory block 2 to print block 3, and print this information using tape recording mechanism 4, work. The time counter 6 is also fed to the second input of the adder 10, and the difference between the codes of the information recording address and the read address determines the degree of filling of the 2-second memory unit. Using register 12, the initial setting of the speed of the tape mechanism 4 can be specified, which is summed up with the difference between the codes of time counters 6 and 10 and the write address. The result of the summation of codes using the unit 13 specifying the carrier speed causes an increase or decrease in the speed of the carrier B depending on the rate of arrival of information. The current time code arriving with the input information is compared by means of the comparison unit 9 with the autonomous time code of the device arriving from the time counter 6. If the current time code begins to exceed the autonomous time code, the comparison unit 9 generates a trigger reset signal. 14j suspend the flow of new information. However, the reset signal of the trigger 14 occurs only when the third input of the comparison unit 9 receives a signal from the output of the media speed setting unit 13 about the maximum speed of the paper. The technical and economic effect of the invention lies in the fact that the device allows to obtain a higher device speed by automatically selecting the most optimal speed of the carrier and improve the quality of the output documents, as the automatic adjustment of the speed of the H1N media ensures the stealth of the spaces on the document. For-mula invention n. And. A device for recording information on the author. St. No. 591882, characterized in that, in order to improve the speed of the device, it contains a write address counter, a media speed setting unit, a register and an adder, the first input of which is connected to one of the address inputs of the memory unit and the output of the write address counter, whose input connected to the input of the decoder and the register, the output of which is connected to the second input of the adder, the third input of which is connected to another address input of the memory unit and to the time counter, and the output of the adder through the speed reference unit is connected to the tape zhnym mouth. the mechanism and the input of the comparison block.
