A change in the division, no matter how it is This procedure has the advantage that the pro-slightly requires a corresponding change programming of the computer program considerably changes the markings on the paper loop. The is simplified and on many subroutines of printing only a single line, e.g. B. one Computer can be dispensed with. However, it will be for final result outside of the intended any change in the division of the space to be printed on the recording medium sheet is not Data on the recording medium a new paper possible, this line is then in the corresponding loop necessary, with the output of computer- the space of the subsequent sheet printed what data has to be interrupted during the time, 20 can not only lead to a waste of space, while the operator often does not change the paper loop but also the printed results. From this it can be seen that such a thing makes clear.

The method is only advantageous for such cases, the object of the invention is to provide a device for to create a very large number of the species described at the beginning, in which the nicely divided forms are to be printed. 35 by the pro-off given on the paper loop the German patent specification 1081701 is a gram format defined by corresponding, in Device has become known in which the two signals stored in the data source are changed can combine basic possibilities.

can be combined with each other. The device according to this object is achieved in that one of the German patent specification 1 081 701 is provided for the 30 logic circuit which, under the control of a high-speed printer, is used to fill out the stop and fast-advance signals of the For-Form, which contains its information in the essential matgenerators only when issuing additional control depending on the markings on a signal by the data source, the feed mechanism moves in and out of the endless paper tape asynchronously with the recording medium for the recording medium. In contrast to 35 switches, so that "the format given by the format generator before the type of devices described last can be changed by the signals of the data source in which the recording medium is the same, and that the logic circuit moves a moderate step further and in the case of Control circuit ', which are sent by a data source that can be given by the occurrence of certain positions, an arbitrarily selectable amount of data, there is the possibility of the known 40 times the normal line spacing marking device, the transport speed of the line feed signal the feed mechanism speed of the To influence the recording medium, for the recording medium transport for a what happens in that certain, at the end of the fast feed switches on, the feed of a column of computer data is assigned a fast mechanism by means of a stop circuit of the transport signal, which the recording logic circuit either via the control circuit up to the next desired position on the basis of the line feed entered, at which the printing of the next data block signal from the format generator begins. With the device according to the signals emitted at every line step or according to German patent specification 1 081 701, there is the possibility - directly via the stop circuit due to a suitable design of the computer 50 from the format generator in the program - to the transport speed of the binding with the stop signal to act on one of the recording media associated therewith. So advantageously the data source supplied control signal can be switched off. In the device according to the invention, there may be speed between two columns of data, so optionally two controllable paths, namely the device according to German 55 on the one hand via the program loop (PC signals) in patent specification 1 081 701 does not offer any possibility to break through the connection with these assigned signals (CJf the markings of the paper loop predetermined signals) from the data carrier and on the other hand via the distribution scheme on the sheet-shaped recording LC signal from the data carrier in connection with the voltage carrier. On the contrary, these LC / 1 signals (line pulses) from the feed mechanism device essentially have the task of this 60 nismus for the recording medium. The LC , which defines the spacing of the lines to be printed, when the abundance of information to be transmitted in signals have priority over the signals coming from the format generator on the recording medium sheet for this purpose, which are shown Space no longer fits. This is because, depending on the position of the recording device, the end of the intended space 65 is released into the carrier. Only when is reached by without even any extra for this data source control signals (HOF-CW, space provided data would be discontinued, one of EOF CW) are given which confirm that a corresponding mark on the paper, the Effect of the signals from the format generator

which is an inverse counter and counts down by one unit upon receipt of each of the aforementioned line count advance signals. The counter also has a line count reset input which is connected to the output of a buffer 58. The second additional control signal EOF-CW, which represents a command from the computer, can only advance to the end of the form and then to the beginning of the new form ("end of form" command signal) and is fed to the setting input of a bistable toggle circuit 60 whose reset input is connected in this way that he can receive the stop signal HOF-PT. The flip-flop 60 has a negative output and an affirmative output. The assertive output supplies a signal which is a delayed »end of form« command signal EOF-CW . The last-mentioned signal is fed to a gate 62 which receives the fast feed signal EOF-PT as an additional input signal. The output of the gate 62 is fed to the buffer 58 together with the “start of form” command signal HOF-CW. The signal HOF-CW is also coupled to the input of a first buffer 64 together with the output of the line counter 56. This line counter output is referred to as the confirmation output and supplies a buffer input signal TJC = C, that is, as long as the line count is not equal to zero.

The output of the flip-flop 60 is also connected to an input of a gate 61, the other input of which receives the signal EOF-PT. The output of the gate 61 is coupled to a buffer 63 together with the HOF-CW-S \ gna \. It should be noted that the gates 61 and 62 as well as the buffer 58 and 63 receive identical logical arguments, so that they could accordingly also be combined in a single gate-buffer circuit. In practice, however, when signal amplification is not provided, it is preferred to use separate gate-buffer circuits.

The output of the buffer 63 is connected to the setting input of a second bistable multivibrator 66, the reset input of which receives the HOF-PT signal. The negative output of the second flip-flop 66, which is denoted by FF 66 , is connected to an input of an AND gate 68. Another gate input is connected to the negative output of the line counter so that it receives a gate signal LC- 0, that is, only when a line count of zero is present. The confirmation output of the second flip-flop 66, which is labeled FF-66 , is connected to a first AND gate 70 which receives the stop signal HOF-PT as a further input.

The outputs of the gates 68 and 70 are combined in a buffer 76. The output of the buffer 76 is connected to the setting input of a first bistable multivibrator 78. The reset input this flip-flop is connected to the output of a second

ίο AND gate 80 connected, which the output of the first buffer 64 as an input. The aforementioned "imprint completed" signal and that "No error" signal, indicating the non-occurrence of any error during the previous printout represents, are supplied to the second AND gate 80 in addition.

The confirmation output of the first flip-flop 78, which is a delayed form of the represents the signal fed to the setting input, and a command to stop the movement of the Paper web is fed to the input of the brake 28 after it is amplified by an amplifier 82 has been. The negative output signal of the first bistable multivibrator 78 represents the signal

as which is fed to the reset input of the stage and is a command to move the paper web. This negative output signal of the flip-flop 78 is amplified in the amplifier 84 and fed to the clutch 26.

As mentioned above, each data record, as received by the central processing unit 52 and stored in the memory 54, consists of a control word and 75 print data words. When the system is working, the print data words 2 to 16 of the sentence stored in the print control memory 54 are first read out and printed out. After such a printout has been completed without errors, the reading out of the first word, ie the control word, is initiated. During this interval, the "end of sentence" command signal ER is fed to the print control unit 53, where it causes an operational display and ensures that the associated program in the central unit 52 is switched over so that a further print is suppressed.

The following table summarizes the various cases that are recognized by the Input conditions during the operation of the device according to the invention for the vertical division of forms occur under the combined action of the various signals.

The once initiated movement of the paper web 10 - thereby evoked HOF-PT pulse "occupy one" until a hole in the row 36 through the sensor - acts in conjunction with the signal FF-66, which device 44 is detected. The detection of the circuit 66 derived from the confirming output signal of the tilt hole of the marking 36 of the paper strip 30, the becoming conductive generates a "one" pulse as an HOF-PT signal. Bi- AND gate 70, which means that the buffer 76 nary ones are then fed to both inputs of an output signal to the setting input of the Kippersten AND gate 70, so that it delivers stage 78 conductive. This has energized the brake 28. The output of the gate 70 is fed to the buffer 76 and the release of the clutch 26, so that a buffer output signal is generated 40 the paper strip feed is above the indicated position, the first bistable flip-flop 78 goes out and the signal HOF-PT accordingly switches the "on" state. A corresponding off returns to zero. As before, the occurrence of the output signal "one", which is derived from the flip-flop stage of the / iOF-PT pulse "one" becomes the bistable flip-flop \)) , energizes the brake 28, so that the movement of the stages 60 and 66 back.

Drive shaft 22 is interrupted and thus the movement is 45 The WA state exists when the first addition of the paper web, the paper strip and the control signal HOF-CW is "zero". The signals; Gear 46 is stopped. Since the other output HOF-PT and EOF-PT are both "zero", since the output of the flip-flop 78 returns to zero, the aforementioned paper strip overflow is assigned, the clutch 26 is de-energized and the motor. Under these circumstances, the state of the Signal 24 from the drive shaft 22 separated. The HOF-PT- 50 EOF-CW is irrelevant. As a result of the completion of the signal, the line counter 56 also supplies reset pulses to the two preceding imprints and is bistable flip-flops 60 and 66. The self-delay is reset. The line feed signal LC causes the flip-flops to prevent the resulting resetting of the line counter to the number, the actuating effect from influencing the above-described work of the required number of line spacings corresponding to the first AND gate 70. Thus speaks, over which the paper web is to be advanced as far as the paper strip 30 over the detected hole.

The state Wl-B occurs when the number of lines In a similar way, case II shows how one of the "zero" has been reached, so that an overdrive signal dependent on the off position of the recording medium is no longer sent to the AND gate 80. Feed signal and an additional control signal arrives. In order to ensure that the flip-flop 66 mcinsam can be used to put the device in its reset state, the signal io must bring a certain state. The EOF-CW calls for "zero". Under these conditions, the arrival of a hole in the marking 38 is insignificant according to the state of EOF-PT . With the flip-flop 66 once the movement of the paper web has been initiated, the gate 68, which has become, now produces a signal EOF-PT , so that this is done by the / \ F-66 signal and by the line paper feed lasts until the feed signal LC = 0 is excited in the marker 36, active.

A considerable simplification of the work of the was available. So it can be B. When creating the programmer is possible if a sufficient number of invoices or balances in the predominantly large number of repetitions of the print format 35 number of cases is desirable that the method is given, either in successive in a corresponding in case II Expires the forms or forms or at a distance. For example, the end of the form can display lines within a given form. constricting rapid advance signal EOF-PT the last line of example, it may be desirable to a loading on each print form and the the form arbitrary number of lines within a superiors 40 beginning indicating stop signal HOF-PT the first line transferred form without regard to other comparison of a Represent form. Under normal changes and deviations in the remaining part conditions, in which more space for a certain of the form to give a double spacing. If only the line count is used, the burden on the programmer, as indicated by the "Form, the burden on the programmer is that the 45 end of sheet" display is permitted, the printing will be programmed with correct line counting data. where the invoice at the head of the next form continues with the last position of the paper web at any time. This condition follows the procedure of being careful. This procedure does not require it to be specified by FaIMI.
On the other hand, a situation can arise in which the programmer, but it also takes additional time to complete the calculation, only a few lines required by the central processor of the computer. changes or maybe only a single line is needed, it also reduces the reliability of the contains the total amount.

In this way, the desired paper circumstances, it is obviously desirable, the thrust can easily be achieved according to the conditions 1A and 60 together with the other data on I-ß of the table above. So can put the same form. Where the procedure is the " beginning of form" command HOF-CW programmed vertical form or format division, which initiates the movement of the paper web is controlled by the paper strip (as with the and continues until the "beginning of form" mark in the German patent 1 081 701 described ments corresponding stop signal HOF-PT after 65 device), such a change cannot be carried out without the arrival of a hole in the marking 36 of a special process, the paper strip 30 opposite the photocell 44 usually the Interruption of the pre-print run. It should be emphasized that programming includes tot. On the other hand, the sole requires

Line counting has a considerable computer and programming time for the operations which are essentially repeat operations.

With the present device, however, repeat operations are effectively handled by means of automatic programming commands without sacrificing the flexibility which is required in such special cases as described above. As the example given shows, the invention offers the possibility of suppressing the method of format division, which is prescribed by the conditions of case II, simply in that the second additional control signal EOF-CW becomes "zero". Under these conditions (case III-B) the fast feed signal at the end of the form has no consequence, since the line feed signal LC controls the format and form dividing process. Thus, if the actual available space allows the printing of one or more additional lines after the print line corresponding to the JSOF-PT signal, such printing can be carried out on the same form by using the line feed signal LC .

The fast-advance and stop signals do not necessarily have to be given through holes in a strip of paper. It is only necessary to provide usable display means which move synchronously with the paper web and can be detected at the reading point. In the same way, the pulses of the line step signal LCA do not necessarily have to be generated in the manner shown in the figure. For example, means could be provided for recognizing corresponding characters by magnetic means, the characters being periodically arranged at intervals that correspond to the spaces between the lines on the circumference of the gear wheel 46, or the paper web could

ίο carry such marks of their own accord, of which the LC / 4 pulses can be obtained.

The LCA pulses could be used to operate an ordinary counter, the output of which is compared with the digit of the line feed signal LC .

The invention is not limited to devices for the vertical division of forms of a paper web, which is to be printed with data derived from a computer. The invention to-

ao also encompasses the format division of data on various other types of data storage means by relocating the latter, so that the data transfer to the desired, form-defining Positions takes place. It is also clear that

as the medium to which the data is transmitted, does not necessarily have to be stopped for data transfer when data transfer is in progress can be carried out properly even with a moving medium.
