(54) DEVICE FOR POINT RECORDING INFORMATION

The invention relates to the field of automation and computer technology, in particular, to devices for visual presentation of information.

A device for point recording information containing a decoder made according to a two-step scheme, the second stage of which is made on ferrite cores with several windings, a printing unit with memory elements on thyristors fl.

It is also known a point information recording device containing memory blocks. DeniFrator and a print unit connected to the front-end mechanism, the output of which is connected to the speed sensor, control trigger, element OR 2J

The Century of the ISTP device for the information device, at registration point 11a, is first degrafted. and then stored in the first memory elements and the speed sensor sysnal is rewritten into the secondary memory elements, which is associated with the large number of quantities (the connections between the depressor and the printing unit, and then the complexity of manufacturing the pei device.

The purpose of the invention is to simplify the device.

This is achieved by containing the groups of elements AND, the group of elements OR and the shaper of the row width, c) 1G10Lnenny in the form of a connected trigger, generator and counter connected to the zero input of the trigger, the single input of which is connected to the output of the speed sensor and to the unit print connected to the trigger control, the counter outputs are connected to the inputs of the depressor unit and to one of the inputs of the elements AND of the first group, the other inputs) are connected to the trigger unit); Schler1, connected to the memory unit One of the second groups of the second group is connected to the Bxo.iy device, the other inputs are to the top of the control trigger, and the outputs of the first 1 of both groups are connected to the input elements of the OR group, BLIXO / UI of which pp.1 turn to alres1P -1M inputs blockg) In memory, the inputs are an I.1I element and are connected to

yyhol m memory blocks, the output is to the de-diffuser connected to the memory block. fia drawing is a representation of the block diagram of the device.

The device for dot recording of the formatting and contains the shaper of line 1, made in the form of successively connected trigger 2, generator 3, counter 4 connected by one output to zero input of trigger 2. Other outputs of counter 4 and the first inputs of the device are connected to one of the group inputs elements And 5, 6, respectively.

The outputs of the And 5, 6 elements through the OR elements 7, 8 are connected to the address inputs of the memory blocks 9, 10, to the bit inputs of which the second inputs of the device are connected.

Output) p blocks of memory 9, 10 through the element OR 11 are connected to the first input D0 of the indicator 12, to the other inputs of which are connected to 11 inputs of the counter 4; the outputs of the decoder 12 are connected to a print unit 13 containing amplifiers 4 and a print time driver 15. The print unit 13 is connected to a tape drive mechanism 16, the output of which is connected to a speed sensor 17 connected to the print unit 13, a single trigger input 2 and a control trigger 18 connected to the memory blocks 9, 10 and other inputs of groups of elements And 5, 6.

The device works as follows. After switching on the bridging mechanism 16, the speed sensor 15 generates a pulse corresponding to the movement of paper by a predetermined amount (example, 0.5 -; - 0, b mm.

By the impulse of the speed sensor 5, the pre-zeroed triggers 2, 18 are set to one.

The potential from the single output of the trigger 18 is fed to the input “writing the memory block U, to the input“ reading the memory block 9 and to the first inputs of the Iba elements, 5i, allows writing the input information to the memory block 10 and reading information from the memory block 9 .

The number of cells of each of the memory blocks 9, 10 is equal to the number of writing electrodes of the tape drive mechanism 16, and each memory cell corresponds to its own writing electrode.

When recording information in the memory blocks, the cell address is determined by the value of the input information, and the sync pulse is recorded as a bit and computed by the input information.

When the trigger 18 is in a single state, the input information is through Iig elements, OR 8 is sent to the address inputs of the memory block 10, the discharge input of which receives a sync pulse followed by this information chipper.

And the recording of information and the memory block K) is made; moreover, if some values of the input information will be repeated several times, then state C (of the corresponding cells of the memory block I) will be confirmed.

One at a time when information is written to the memory 10, a zero is read out; how many information from memory 9, so the memory blocks are zeroed before the start of registration.

The formation of the address of the memory block when reading information occurs in the following way.

I use trigger signal 2 to start generator 3, the pulses of which enter the n-bit counter 4, where n is the number of bits of the input information.

The codes of the digits of the counter 4 through the elements I5, OR 7 arrive at the address buses of the memory unit 9 and simultaneously arrive at the second inputs of the depositor 12. The decoder outputs (the number of which is defined as N 2) through the amplifier 14 are connected to the corresponding writing electrodes iG mechanism.

The pulse repetition frequency of the generator 3 provides reading from all the cells of the memory block 9 during the time of paper pulling by 0.5 -: - 0.6 mm.

The transfer pulse of the counter 4, the trigger 2 is zeroed, the generator 3 stops working until the next pulse of the sensor 17 arrives, the counter 4 is also set to the zero state.

On the next second pulse of the speed sensor 17, the trigger 18 is thrown and the zero output switches the memory block 9 to "write" and the memory block 10 to "read; at the same time, the enabling signal appears at the first inputs of the elements I6 |, 5l elements Ib, 5i are prohibited.

The input information enters through the elements I6 |, OR f to the address inputs of the memory block 9, to the bit input unit of the mi 9 9 the input information clock signals are received, a sign of the presence of information, and the memory is being written to the memory block 9.

By the second pulse of the speed sensor 17, trigger 2 is again set to one; the generator 3 and the counter 4 are started. The first generator pulse at the output of the counter forms code 00 ... 01 - corresponding to the address of the 1st cell of the memory block 10 and the content of the first cell is read.

In the previous, first cycle, in 1-uk) the cell of the memory block 10 a sign of the presence of information was recorded, then a unit is read from the cell and

This PLI 1 impulse is generated by gating decipher torto 12, at the input of which we receive code 0 ... 01 ccP of counter 4.

T (11d at the first output of the digiraphator;) 12 a pulse appears, which is forced through the corresponding amplifier 14 to write current to the first hissing electrode. The duration of the write current pulse is determined by the type of paper used and is determined by the print time driver 15 by the pulse of the speed sensor 17.

After reading from all the cells of the memory block 10 with decoding those values of the counter 4. by which the information from the memory block 10 was read, the transfer pulse of the counter 4 triggers 2.

Each value of the information — information availability prizapak — is read from the memory block only once, so only one dot is recorded on a 0.5 mm paper length. This provides decimation of unchanging information. Without this, no changing value of information is lost, since each value of information corresponds to a memory cell.

In the proposed device, the decoder 12 is located along the memory blocks, is executed on large integrated circuits, and the reading of information from the memory cells is performed sequentially. This reduces the communication between the blocks and the elements of the device, simplifies its design and reduces the complexity of manufacturing.

The introduction of a line formatter allows thinning out unchanging information, which excludes the possibility of destroying the base of bumgpie and maximizes the deterioration of writing ELCT) (h.
