Description ;

The present invention relates generally to specific Printing devices designed for data processing systems, in particular on an electronically controlled one Matrix thermal printer with which the appear on a video display connected to a data processing system Data can be reproduced.

In your field of data processing systems, systems have become developed and used for several years, which use different output devices, the information in for human readable form in order to provide the user with the results obtained by the data processing system to display. Various devices were used for this, for example console printers, chain and other printers, Card punches and card printers and the like. These mechanical printers, however, are slow-working Devices, compared to the processing speed of the data processing systems. In addition to that through The problem caused by this discrepancy was found to be the typical "output" of a printer by far exceeds operator requirements at a given time, even though the printed one Information is useful sooner or later. So when preparing typical computer printouts, a considerable amount of time is involved A lot of paper and a lot of machine time wasted.

In an effort to overcome some of the disadvantages inherent in mechanical printers, video displays have been developed that the information of interest to the operator, for example on the screen of a cathode ray tube make visible in the form of an image. In most cases the video display is combined with a terminal,

909881/0741

which makes it possible for the operator, the stored by the data processing system and for display change brought data. This not only has the advantage for the user that he is familiar with the data processing system can work in interactive mode, but such video displays can also be to some extent independent operated by the data processing system, which frees the computer to process other programs © will. The use of such a video display thus enables a data processing system in a given Processing time more data. In addition, information that is not required is not printed out, which saves both paper and paper as well as saving machine time.

While the introduction of video displays eliminated or reduced a number of computer-related problems, they emerged at the same time other problems. In typical applications, after the user can read the information stored in the system changed, a hard copy of the updated information may be desired. This may be provided by the printer that the Console printer or another device belonging to the system can be reached. Such a printing process however, it has the disadvantage as explained above that precious computer time is consumed. There continue to be the video display devices can be set up at a remote location, there is the disadvantage that the user siGh is not near the printer, which leads to a delay in waiting for the printout.

In view of the above-mentioned disadvantages associated with conventional printing devices equipped with video displays Adhering to data processing systems, it is the audible thing The aim of the present invention is to provide a printing device

909881/0741

create the information appearing on a video display can print economically.

Another object of the invention is to provide a printing device which is capable of appearing on a video display Can print information without interrupting the host computer to obtain the information to be printed necessary is.

It is a further object of the E _r invention to provide a printing device which can print the information appearing on a video display information, wherein the printing means of their mechanical equipment itself with respect inexpensive to manufacture and maintenance, and in addition due to a simple construction by high Reliability.

It is a further object of the invention to provide a printing device which corresponds to the above objects, however, is of simple construction and can be made from relatively inexpensive components for an economical Provide solution to the problems outlined above.

The objects and advantages explained above are achieved by the thermal printer according to the invention. The printing mechanism has a platen operated by a stepper motor that is used to advance one over the platen guided, treated paper strip is used. The inventive Thermodruckeinriehtung comprises several mounted on one or more support bodies and in a straight line arranged thermocouples. The support body for each of the thermocouples is on the frame of the printing device in a V / iron mounted that allows the thermocouples to be positioned so that they are in relation to the support plate

909881/0741

a degree of freedom can be set. this will achieved in that the support body is mounted on the frame by means of a flexible hinge. The supporting body is biased against the platen by an adjustable pressure mechanism, and the pressure mechanism presses the thermocouples against the surface of the paper strip sliding over the platen.

The electronic control for the printing device contains an interface for receiving digital information from a digital memory buffer in a video display or the like. The digital information is in the same way as it is received by the display, i.e. the data is saved character by character, according to proceeding to the right, starting with the left character, starting with & r in the top line of the display and with the bottom line of the display stopped v / ird.

A microcomputer is provided within the electronic circuit for controlling the printer, its functions by the data contained in a read-only memory being controlled. The microcomputer controls the electronic circuitry of the printer mechanism and remotely the data stored in a memory during the printing process in order to convert them into digital matrix point information, which is representative of the character to be printed. The digital matrix point information for each character is then transferred to a first shift register. Then the data is extracted bit by bit from the first shift register shifted into a larger shift register. Once the larger shift register has been filled, the ones in the Register contained data given by drivers to the thermal printheads, which are in each column on the paper several Create points. The microcomputer repeats this process

2S2A1 78-

and creates further matrix points, up to and including all matrix points are formed in a given column of dots related to the data to be printed. Then the stepper motor advances the platen by one matrix point, and a new column appears generated by points. In the preferred embodiment a column of characters displayed on the video display is printed after nine dot columns are formed. Printing continues until all of the video characters have been printed.

According to a preferred concept of the invention, a printer is equipped with an electronic printer control Thermal printer created in which the thermocouples are arranged in a straight line. The thermocouples are arranged so that they come into contact with the side to be printed and they are still mounted in such a way that that they are essentially adjustable in a degree of price with respect to the side to be printed. the Thermocouples are grounded by electronic control circuitry obtained from a video display or other data source Receives and stores data, actuates. The electronic control circuit converts the stored video data into several matrix points, each character being represented by selected points of a point matrix. the Data is printed by first placing multiple thermocouples in a column that are related to the stored data stand, be actuated. After printing the number of columns corresponding to the width of each character to be printed is, one character is reproduced in each stored data line. The system continues in this way, until all of the stored characters are printed in each column.

In the following, exemplary embodiments of the invention are explained in more detail with reference to the drawing. Show it:

Fig. 1 is a block diagram of the electronic control for the thermal printer according to the invention,

Fig 2 to 6 detailed S _c attitude diagrams. Of the electronic circuit device for the thermal printer according to the invention,

Fig. 7 is a sketch in which the most important mechanical Parts of the thermal printer according to the invention are shown are and

FIG. 8 is a left side view of that shown in FIG Printing mechanism.

The thermal printer according to the invention is designed in such a way that it has one consisting of 24 lines of 80 characters each Page prints. Each character in a line is represented by a dot matrix that is nine dots wide and 12 points high. A cathode ray tube display 10 is through a plurality of lines running through the double arrow 12 are indicated, connected to an interface (interface) 14. Dia interface 14- has the task of converting the signal level appearing on the lines 12 into such levels that the AGIA (Asynchronous Communications Interface Adapter) 16 are compatible.

The system shown in Fig. 1 also has a clock generator 18, the frequency of which is preferably by a highly stable crystal is controlled. The clock 18

909881/0741

generates a sequence of clock pulses on line 20, which is connected to a bit sequence generator 22. The bit sequence generator 22 contains a selection switch 24 with which the speed of the pulses generated on the output line 26 can be selected / grounded. The pulse speed is a manually selectable speed which is related to the speed at which the AOIA 16 receives information from the screen 10 via the interface 14. The pulses on line 26 are used to synchronize the operation of ACIA 16 with the asynchronous data received from display 10. This process takes place in the manner specified by the manufacturer of the AOIA.

The clock generator 18 also generates two output pulse trains on lines 34 and 36. These pulse trains are marked 01 and 02. The two pulse trains are not in phase with each other; one pulse train is used to control the internal Functions of the microcomputer 32 is used, the other pulse train controls the communication between the Microcomputer and the other parts of the system connected to the microcomputer.

The AOIA 16 is connected to an address bus 28 and to a data bus 30, which in turn are connected to other elements of the system. Has the ACIA 16 once received a from dsm. Screen 10 received characters recorded, it generates a signal on the interrupt line 31 'which is connected to the microcomputer 32. The interrupt signal on line 31 causes microcomputer 32 to eventually initiate an internal interrupt routine. In this routine, the microcomputer 32 finally puts an address on the address bus 28 and this address is recognized by the AOIA 16. In response to this

909881/0741

Address gives the A0IA16 the character on data bus 30, and the microcomputer 32 removes the data from the data bus 30 to be stored in an internal register for subsequent purposes Transfer to the read / write memory 62 to store. The memory 62 will hereinafter be referred to as RAM for short whereas a read-only memory is referred to as ROM for short v / should be grounded. This process of transferring the digital data to the RAIi continues until the microcomputer 32 determines that all of the characters displayed on screen 10 are stored in memory 62. Afterward printing can be started.

That in JFig. 1 further includes two address decoders 38 and 40 which are connected to the address bus 28 and operate during the printing operations. The address decoder 38 responds to a special address on address bus 28 and causes the eight bits currently represented by the Microcomputer 32 given on the data bus 30, in an 8-bit shift register 4-2. Then the from the 8-bit shift register 4-2 received data is shifted bit by bit into a 72-bit shift register 44. Thereafter, the microcomputer 32 initiates others Data transfers from the RAIi 62 via the 8-bit shift register 42 to the 72-bit shift register 44 until the latter is filled.

According to the present invention, any of the preferably Thermal heads (3) used generate a maximum of 96 matrix points if all thermocouples in each Head can be activated at the same time. The heads become special manufactured by Gulton Industries Inc. of Metuchen, New Jersey, and they are similar to model DM1 + 99-28F12, which has a head with 99 points. This unit could be used in the arrangement according to the invention if some changes have been made,

909881/0741

292417a

to take into account the fact that this unity V / has more resistance elements than in the ordinary Unit are available.

It turned out to be cheap, at the same time only activate about 1/4 of the thermocouples in each head. This will meet the requirements for the energy supply reduced, since a maximum of 1/4 of the thermocouples can be operated at a given time. In addition, this measure reduces the problems in connection with the heat development in the thermal heads. However, to enable all of the items required in a given printing operation, four Operation cycles required to produce a column of up to 288 points.

When the thermocouples are actuated, the address decoder 40 responds to a pending on the address bus 28, of the Microcomputer 32 there generated address. The address decoder 40 causes the register 45 to set the Data bus 30 stores pending data. The ones in the register 46 stored data are given to driver 48. This is done in the manner that a selected Drivers of the four driver groups 48, which are switched to selected bit positions of the shift register 44, is operated to special thermocouples in ώη thermal heads 5 °> 52 and 5 ^ · to drive. The four different Combinations of data which can be stored in the register 46 for identifying the four groups detected by the driver 43 so that 24 thermocouples in each thermal head 50, 52 and 54 are activated may or may not be, depending on those stored in a given bit location of the shift register 44 Data; the thermocouples are then activated

909881/0741

speaking during each of the four actuation (burn) cycles. Of course, the shift register 44 for each of the four firing cycles filled with associated data so that the thermal heads 50 » 52 and 54- columns of points made on paper corresponds to the desired print data. This "operation is carried out under the control of the microcomputer 32 and the like Control store 60 in the manner to be explained below.

After the drivers 48 have activated all of the thermocouples desired with respect to a given column of information to be printed by the printer, there are the microcomputer 32 an address on the address bus 28, which is recognized by the address decoder 40, which has the consequence that the register 46 the data on the data bus 30 saves pending data. These data stored in register 46 are used to operate the motor driver stage 5δ, so that a stepping motor 58 by a predetermined Number of steps advanced itfird. The stepper motor 58 is coupled to a charging plate, around a treated paper strip that is in contact with the thermocouples in thermal heads 50, 52 and 54, advance. In this way, a free space on the paper strip comes into contact with the thermal heads 50, 52 and 54, so that a subsequent printing operation on a free dtelle of the paper strip takes place.

An implementation of the system shown schematically in FIG. 1 is shown in FIGS. For reasons For the sake of clarity, the connections relating to the data bus and the address bus have been shown in these figures omitted. The data bus comprises eight lines which are connected to all points connected to DO-D7 are marked so that everyone can be marked with DO, for example.

909881/0741

te point is connected to another point also marked with DQ, etc. Similarly, the address bus comprises 16 lines which connect the points of the circuit marked with AO-AI5. The rest of the _c in the Pig.2 to 6 represented S attitude is explained by the drawing itself, but should optionally v / ground for reasons of better understanding, a detailed explanation below.

In Fig. 2, the bit sequence generator is generally associated with the Reference numeral 200 indicated. It has several open terminal pairs 5OO, 600, 1200, 2400, 4-800 and 9600. One these pairs of terminals must or the like by a jumper wire. connected with the specially selected pair of terminals depends on the data transfer rate of the video data on the connection link 202 from the screen (not shown) can be received. Possible data guessers; are 300, 600, 1200, 2400, 4800 or 9600 bits per second. The video data appearing on line 202 is converted by an interface level converter 204. The video data is converted to a level compatible with the AGIA 206. Should be the thermal printer be connected to another display that has a different data transfer rate, a Another pair of terminals in the bit sequence generator can be connected in order to ensure synchronization with the ACIA 206.

The AOIA 206 and the bit sequence generator 200 operate in known per se to convert the serially received data bits, which are available in ASCII code, into parallel Convert data that make up the character to be printed. The way the rest of the work in Pig. 2 illustrated components is explained in more detail below.

909881/0741

A shown in Fig. 3 decoder 301 is through the Microcomputer 208 (FIG. 2) is controlled to select various types of control operations to be performed by the electronic control circuit of the thermal printer are executed. For example, if by the microcomputer 208 a selected address is given on the address bus, the decoder 301 gives a signal to its Output pin 3 »which in combination with a read / write— Signal (H / W), an AND element 302 switches through and a monoflop 304 triggers. The monoflop 304- generates on the Output pin 13 is a 5 millisecond gate signal referred to as the printer burn signal (PRB) will. The PRB signal is used to set the AND gates 306 and the circuit MC1411 in conjunction with the data stored in register 308, causing circuit MC14-11 to one of the thermal head driving transistor pairs 310 operates. As a result, one of the output lines marked with Group 1, Group 2, Group 3 or Group 4 generate a signal.

The particular thermal printhead used in the preferred embodiment of this invention has a plurality of resistive elements (referred to as thermocouples) that are in a straight line at 0.56mm center-to-center spacing. (22 mil) are arranged. Each head has 96 such Resistance elements, where the elements 1, 5 »9 --- 93 in group 1, elements 2, 6, 10 ... 94- in group 2, the elements 3 »7» 11 - ·· 95 in group 3 and the elements 4, 8, 12 ... 96 are included in group 4. The group signal generated by the circuit of Fig. 3 selects one of the four groups for each burning process (printing process).

The rest of the selection of resistance elements is made by the Circuit arrangement shown in Fig. 4, which is an 8-bit shift register 400 and the 72-bit shift register.

909881/0741

These elements consist of the components with the type designation 74-LS164-. Each bit position of the 72-bit shift register is coupled to one of the sockets 3Λ , J2 or J3 via a driver, a circuit with the type number MC14-11. Each of these sockets has 24 contact pins corresponding to a quarter of the resistance elements in a thermal head connected to it. As already indicated above, the special group of resistance elements is selected by the group signal generated by the circuit according to Jig.3. Diode switches in each thermal head use the group signal as well as the data from the 72-bit shift register to activate the desired resistance elements that are to be actuated in a group during a burn process.

Those skilled in the art will recognize that there is each of the thermocouples with the remaining thermocouples within a thermal head is arranged in a straight line, a straight dotted line with up to 288 dots during four consecutive ones Firing cycles is formed. Those skilled in the art will also recognize that such an approach is desirable because the required electronic circuit arrangement is not as extensive as with other possibly to be used Procedure; In addition, the requirements ^ to the Energy supplies are not that high. The thermal printer according to the invention can therefore be manufactured more cheaply than one Printer in which all 288 V / resistance elements are activated at the same time.

The circuit arrangement shown in Fig. 3 further includes a motor driving circuit 312 that the windings of a S _c hrittmotors (not shown) energized · This step motor is used for driving the platen of the printer to advance a treated paper strips. After four firing cycles have been completed, the micro-

909881/0741

computer registers 308 with data corresponding to the next step position of the stepper motor, what by a decoder 309 is decoded. When the stepper motor drive signal is applied to the line SMD, the motor driver circuit 312 is operated to according to the data contained in register 308 to actuate the winding of the platen stepper motor. This will the platen rotated, and a free pressure point on the paper strip driven from the platen comes into contact with the thermal heads.

In the operation of the preferred embodiment of the invention, the stepper motor is advanced each time a complete column with up to 288 matrix points is formed. When reproducing the whole on the screen When the image appears, this process is repeated until up to 720 columns of points have been formed. This allows Screen characters using a dot matrix with a width of 9 points and a height of 12 points can be reproduced for each character. The one with the printer according to the preferred embodiment of the invention Printed information therefore comprises up to 24 lines, with up to 80 characters in each line. The apparatus of the invention is used to generate a column of points at a time, the Points themselves lie in each of the 24 character rows that are generated on the paper strip. Hach-de ^ i nine such Columns of dots are formed, one character is finished in each of the 24 lines or rows. The actual The circuit must therefore contain the video image data, which begins serially character by character on the left and progresses to the right with each line are received, convert into parallel data information which comprises columns of points on the Print side are to be formed. In other words: the printer according to the invention prints as a function of character data which are offered to it serially and which are line by line

909881/0741

run across the page, one at a time
Column of dots laterally along the side. Those skilled in the art will recognize that this method saves costs because fewer thermocouples and circuitry are required than conventional ones
Institutions.

The transformation required to carry out the function explained above is achieved in part by the circuit arrangement shown in FIG. The circuit comprises two shift registers, a first shift register 400 which receives dot data in parallel from the data bus and converts it into a serial bit sequence. This bit sequence is then shifted into a second shift register which comprises nine shift register units connected in series. The shift register units are of the 24LS164- component type. The microcomputer 208 activates
the line SELECTION (select), which causes
that the decoder 301 the bits A12, A15 and A14- on the
Address bus decoded. These bits are encoded by microcomputer 208 so that a pulse is applied to line SOLK. The read / write line (R / W line) x ^ is set by the microcomputer 208 to indicate that data is pending on the data bus and that
the register identified by the address on the address bus is to receive the data from the data bus. In
in this case the 8-bit shift register 400 responds to the read / write signal (R / W) and the signal SOLK and
takes the data from the data bus. Subsequently changes
the microcomputer 208 the level on the line R / V / and generates eight times a pulse on the line SCLK, whereby the 8-bit shift register 400 the data contained therein serially into the 72-bit shift register (the in
4 * illustrated components 74LS164 *) clocks. The microcomputer 208 continues to put data into the 8-bit shift register

909881/0741

400 and then this data into the 72-bit ~ Shift register until the latter is filled »Then the ones contained in the 72-bit shift register Data used to set the resistance elements in the thermal heads according to the circuit shown in FIG Fig. 3 to activate selected group.

The ASCII data received from the screen is converted to a "dot" representation so that it can be used in for suitable for printing. This is done on following way. Before doing this, however, remember that it modifies any character received by the screen and is stored in the RAM in the form of a matrix of 24 lines and 80 characters per line. When generating from "point" data to the stored ASCII characters at a given time, consider a column of 24 characters, one character on each line in RAM. Then every fourth character in the column is considered, i.e. for the first burning process the first, fifth, ninth, thirteenth, seventeenth and considered twenty-first signs.

The control stored in ROM 60 causes every fourth character in a column in a register saved x- / ird. Then each character and the current dot column number is used to create a memory location to be addressed in a ROM table; here is the address at which the dot pattern is present in the ROM. Then the point pattern is fetched from the second ROM table location and placed in a RAM memory location. each time the second ROM table is addressed, 12 usable data bits are read out. The 12 bits set the points in the current point column for The ROM 60 causes twelve bits to be read out for each of six characters, making 72 bits

909881/0741

comprehensive data stream is formed.

Next, the 72-bit data stream is staggered in time in groups of 8 bits each brought an 8-bit shift register 42 and shifted bit by bit into the 72-bit shift register 44 until all 72 bits are stored there. Assuming that the point information for the 1st, 5th, 9th · »13 ·» 17 · and 21st Character is contained in the 72-bit shift register, the ROM 60 and the microprocessor 208 cause that the line "Group 1" (see Fig. 3) is activated, whereby the group 1 of the thermocouples is activated. Then the special thermocouples are switched on as a function of the data contained in register 44, by a series of up to 12 points for the 1st, 5 »j 9 ·» 13 ·> 17 · and 21st charactersii of a column during a first Form burning process.

Then the microprocessor 208, under the control of the ROM 60, fetches the characters of the second group, namely the 2nd, 6th, 10th, 14th, 18th and 22nd characters. The point information for these characters is read out in the explained / feise and loaded into shift register 44. Then the line "Group 2" (see Fig. 3) is activated, and it are as a function of the data contained in the register 44? up to 12 points for the 2nd, 6th, 10th, 14th, 18th and 22nd characters in the column formed during a second burn.

Then the remaining points are formed in the point column during the third and fourth burning process, these points are part of all 24 characters. Then the internal number of points column counter is increased, the platen is rotated further and the process repeated to the second column of periods for each of the 24 characters

909881/0741

to form a column of characters on the screen. This process is repeated until nine columns of points are formed i.e. until a column of characters is printed on the paper strip.

Once a column of characters is ready, each character can consist of a matrix of 9 x12 points the microprocessor 208, under the control of the ROM 60, moves the next column of ASCII characters and begins converting them into to process in the manner outlined above. The process is repeated until all 80 columns of characters are printed are.

In the above description, reference was made to the circuit diagrams in FIGS. 2 to 6. The circuit elements v / ground controlled by the contents of the ROM. An illustrative example of the address and data content of the ROM is shown in Tables 1-1 through 1-5 below.
