The invention relates to a device for parallel printing of information in a Magnetic storage, for example in a magnetic drum, magnetic tape or core storage, in binary-decimal coded form are included, in which the memory marks a shift of the Type carrier of the printing unit cause the information to be printed in decoded form reach.

Such devices known as line printing units are used, for example, as charge printers Used in electronic telecommunications, especially telephone systems, where the decadic Dialing pulses for connection establishment are converted into a binary code form. Become useful the charge pulses are also transmitted in this code form. You must then, since the information, such as subscriber number, day, time, etc., are to be printed in decadic form, are decoded.

Also in electronic business machines, for example in booking or calculating machines, such line printing units are used. In most cases, the binary-decimal code form is used here used because it greatly reduces the effort required for individual arithmetic units. as

In order to avoid additional decoding and storage devices, printing units have become known in which the information present in binary-decimal form in a memory is converted into decadic form only during the setting of the individual type carriers. For this purpose, the type carrier, on which the characters to be printed (digits or letters) are arranged at constant intervals a , is shifted by a distance that is made up of the addition of the distances assigned to the coded values. For the digits “0” to “9”, for example, these sections are one, two, four and eight times the distance between the characters. In the case of letters, the section of sixteen times the distance would be required. Other sizes of the segments are conceivable with the binary-decimal code.

In a known arrangement of this type, the rod-shaped type carrier is provided with telescopically nested adjusting members which are held in their initial positions against a spring force by locking members. These locking members, which can be actuated by electromagnets, release the setting members assigned to them according to the binary-decimal value of the character to be printed, which now yield to the common spring force and the displacement of the device for the parallel printing of

Type carrier effect according to the addition of the distances covered.

In another known arrangement of this type, the adjusting members are rod-shaped and arranged one above the other. For every possible binary-decimal value such a bar is provided, on which electromagnets are attached at predetermined points, which are for the neighboring Rods act as a solenoid. These solenoids are calculated according to the binary decimal value of the to be printed character excited, so that not only the individual rods are moved, but with this also the associated electromagnet.

These two known arrangements are very complex. While the former is a larger one Contains number of moving parts that interact mechanically and due to the friction wear more or less quickly, the feeds must also be used in the second arrangement the electromagnet can be made flexible. Both arrangements are therefore complex and prone to failure.

Another major disadvantage of these known arrangements is their slow working speed, which leads to the electronic booking and calculating machines whose operating speed is predominantly determined. It exists hence the requirement to use fast printing units in such machines. The above well-known works are unsuitable for this because they use a relatively large number of movable elements which have to be accelerated again with each hiring or advancement.

The invention is based on the object of a device that can be adjusted quickly compared to the known arrangements To create printing work in which as few movable elements as possible are used or

For example, has the parallel done according to a further embodiment of the invention printing unit a capacity of 25 characters per line, synchronous with the movement of the control member, so that there are accordingly 25 memory rows for the the next memory location is only queried then, to provide 20 magnetic core memories.

The number of these control organs only a single switching device for pins depends on the number of possible the clutch necessary. The code used by the switchgear. A binary-decimal code with a maximum of four organs with the assigned type carrier are used in places. In this case, four adjustable pins are required, each offset from those of the neighboring 45. Their distance from one another corresponds to the type of control organ to be arranged. It is useful for the value of the individual codes.

The invention is described below with reference to a magnet 4 acting as an input device In FIGS. 1 and 2, extinguishing elements 5, which are shown in principle at various points, are present, management example described in more detail. Not all of them are also used as magnets, e.g. B. as solenoids or in Understanding of the invention absolutely necessary So other known ways, may be formed. Devices and circuits are omitted. These extinguishers 5 have the task of by In particular, the constructive and switched magnets 4 are placed on predetermined pins functional measures and devices that disengage the points from the type bar 1 are necessary for the realization of the invention to bring.

In the exemplary embodiment, the mutual spacing is the same as the spacing of the settling aisles, that the information content of a parallel pencil 6 corresponds to the values of the one to be used Line graduated in a known manner in the codes. With the binary-decimal system

the distance between the first and the second pin 6 ¹ and 6 corresponds to one division, that between the second and the third pin 6 ² and 6 ⁴ corresponds to two divisions and the distance between the third and the fourth pin 6 ⁴ and 6 ⁸ finally corresponds to four Divisions. The same applies accordingly to the mutual spacing of the quenching elements.

The in F i g. The arrangement shown in FIG. 1 is present several times in a line printing unit and next to one another arranged. Their number depends on the number of possible characters to be printed Row. As explained below, with such a multiple arrangement under certain Requirements the input devices 4 and the extinguishing devices 5 for several control rails 3 be summarized.

If the binary information LOLO contained in a memory row of the magnetic core memory, not shown, is to be prepared in decoded form for printing, the query of the memory row in question and, at the same time, the continuous movement of the control rail 3 in Direction of arrow initiated. The query of the memory row corresponding to the control rail 3 to be set and the movement of this control rail 3 takes place synchronously in such a way that when the first pin 6 ¹ , which is assigned to the binary units digit, is above the input device 4, the assigned binary units digit of the magnetic core memory is queried. However, since the information at this point is zero, ie the magnetic core memory is not marked, the pin 6 ^{1 is} not set. After the adjusting rail 3 has carried out a movement in the direction of the arrow over a division, its second pin 6 ² is now located above the input device 4. At this moment, the second position of the memory row of the magnetic core memory is queried via the program switch (not shown). Since this query of the memory results in a marking for this point, the magnetic coil of the input device 4 is excited by the pulse generated thereby. The armature of this magnet is moved in the direction of the arrow and thereby brings the pin 6 ² into engagement with the type rod 1. This coupling of the type rod 1 with the adjusting rail 3 also ^{moves it in the direction of the arrow, until the pin 6 2} again is thrown off. This is the case after moving over two divisions. The decoupling of the two rods 1 and 3 and thus the ejection of the pin 6 ² can for example take place in that the respective extinguishing magnet 5 is excited as a function of the movement of the control rail 3. However, it can also take place in that, at the same time as the input device 4 becomes effective, that extinguishing magnet 5 becomes effective through the marking pulse of the memory and remains effective until the adjusting rail 3 has carried out the divisions assigned to this value.

After the pen 6 ^{2 has} now been thrown off by the erasing device 5 ² , the third pin 6 ^{4 of} the adjusting rail 3 is above the input device 4. However, this is not set because the simultaneous query of the third binary digit does not result in a marking pulse, that is, this third one Binary digit has the value zero. After a movement of the adjusting rail 3 over four units - the extinguishing magnet 5 ⁴ is not excited due to the lack of a marking pulse or is excited depending on the control rail movement, but remained ineffective - the fourth pin 6 ⁸ finally comes over the input device 4 and is in the previously described Wise set, because the query of the corresponding fourth digit of the memory row has resulted in a marking. Since, as previously assumed, also the extinguishing magnet 5 ⁸ by the adjusting rail movement or the marking pulse

ίο is excited, this fourth pin 6 ^{8 is} thrown off again after a movement over eight divisions. The type bar 1 has thus experienced during a continuous movement of the adjusting rail 3 over a total of sixteen divisions, one after the other, a shift first over two, then over eight, so a total of over ten units. This brings the tenth character of the type bar 1 into print position. In the same way, all existing type bars 1 of the printing unit are set one after the other to those characters which are contained in binary form in the memory rows of the magnetic core memory assigned to them. It can be seen without further ado that the setting of the type bars 1 to the various characters is carried out analogously to the process described above for setting the number 0.

While in the example described above, all type bars 1 one after the other by querying the individual memory rows of the magnetic core memory accordingly can be set to the individual characters via the adjusting rails 3 assigned to them and then in on can be struck at the same time in a known manner against the paper roll 7 of the printing unit the invention can be used with advantage in a variant of the printing unit described above. So can the extinguishing devices 5 for all parallel adjustment rails 3 of the printing unit to one common erasing device are combined when the corresponding pins 6 on be arranged at the same height. The need for a separate input device for each adjusting rail 3 provided, however, remains.

Since the printing unit according to the invention works largely in series, a simplification in which this need is not necessary can be achieved in that all the adjusting rails 3 are moved simultaneously and that the pins 6 ¹ , 6 ² , 6 ⁴ and 6 ⁸ one each adjusting rail 3 are offset from one another to the adjacent adjusting rail in such a way that only a single input device 4 is required for all adjusting rails 3. If the line printing unit is equipped with a large number of adjacent type bars 1, the adjustment rails 3 are expediently combined in groups and a special setting device 4 is assigned to each of these groups. In Fig. 2, such a group of adjusting rails 3 ¹ to 3 ^{4 is shown} in plan view. This group consisting of four adjusting rails 3 is moved in the direction of the arrow. The vertical arrow indicates the point at which the common, in F i g. 2 input device 4, not shown, becomes effective. The settable pins 6 of adjacent adjusting rails 3 can now be offset in such a way that they pass the input device (vertical arrow) ^{one after the other with the continuous movement of all adjusting rails 3 1} to 3 ^4. But you can also, as in the exemplary embodiment

2 shows overlap. In such arrangements of the settable pins 6, however, it is important to ensure that a simultaneous setting of several pens 6 by the common input device is prevented. The in F i g. The arrangement of the pins 6 shown in FIG. 2 shows such a case.

Such an arrangement also has the advantage that the interrogation of the individual adjusting rails 3 allocated memory rows of the magnetic core memory within each group one after the other for however, the same adjustment rails of different groups can take place at the same time. Further results the advantage, provided that those places where the input devices 4 become effective, are for all groups in the same amount that for all adjusting rails 3 of all groups the extinguishing members 5 can be common.

The mode of operation of such an arrangement results from the described mode of operation of the arrangement according to FIG. 1. In this way, all the adjusting rails 3 ¹ to 3 ^{4 are} continuously moved in the direction of the arrow and, depending on this movement, the associated memory row, not shown, of a core store queried. According to the markings contained in this memory ^{row, one or more pins 6 1} , 6 ² , 6 ⁴ or 6 ^{8 of} the adjusting rail 3 ¹ are set one after the other in the manner described above. While the adjusting rail 3 ¹ makes a movement over four divisions behind the pin 6 ^{i, the pin 6 1 of} the adjusting rail 3 ² now reaches the area of the input device (approximately after two divisions). This means that prior to the interrogation of the fourth position of the control rail 3 ¹ associated memory row, the first and, as the arrangement of the pins shown in FIG. 2, the second digit of the slide rail 3 ² associated checked memory row of the magnetic core memory, not shown, will. Similarly, the assigned memory rows of the two remaining adjusting rails 3 ³ and 3 ^{4 are} interrogated at the times at which the relevant pins 6 are moved over the input device.

The nested mode of operation of the individual positions and values of the magnetic core memory requires a pulse generator which is driven synchronously with or by the positioning rails 3 ¹ to 3 * and interrogates the memory in the predetermined sequence. This pulse generator can, for example, be designed photoelectrically and control the core memory in a manner known per se in such a matrix in columns and rows.

In a modification of the illustrated and described embodiment, they can be used as rods Adjustment and control members 1 and 3 shown may be annular. The outer Ring correspond to the type bars 1 and have the types on its circumference. Inside that ring is then the also ring-shaped control member and within this in turn the required Input and delete devices arranged. All type rings and control rings can be used be arranged on a common axis.
