The invention relates to a code selection device in one of a printing unit, its Type carrier, ζ. B. type wheel set, type cylinder or type box, by two rear derailleurs after two Coordinates in front of the pressure point is set, controlled data punch, which is used to select a Number of punches set in two mutually perpendicular directions lying in one plane can be made using a frame in which the actuation of the punch ίο according to the desired code combinations provided intermediate links in one of the numbers the punch corresponding number of fields are arranged.

Typewriter-controlled data punching devices are known which are based on teleprinting technology a key-operated set of different approach selector bars use. This construction is disadvantageous in that the selector rails are different from one another are expensive to manufacture and do not allow conversion from one code to another.

It is, on the other hand, a key operated tab punch machine became known in which a number of arranged in a frame for adjustment in a plane and for the Hole process are provided in a direction perpendicular thereto movable intermediate members for the purpose Change of the code key can be exchanged. However, these intermediate links are each provided with different approaches, so that they are also expensive to manufacture.

On the other hand, it is with the so-called wire printers for card punching machines, in which the Characters are composed of a number of individual elements, known one in two to each other Slidable plate should be provided in vertical directions, with the typeface of the print to be printed Mark is provided with corresponding elevations or cams and for the imprint is advanced towards the print wires. The displacement of the cam plate in the two directions is controlled by the twelve selector pins using a special code, the operate the twelve punches in a column of punched cards in the usual way. That kind of control cannot be used in the printing of document typewriters or booking machines, because there are completely different ratios for the adjustment of the type carrier.

The invention is based on the idea of converting the print code selection device, which has become known from wire printers, into one of one

zip the cam plate in the code selection device one of a printing unit of the aforementioned Type of controlled data punching device to use to operate the punch.

The code selection device of the type mentioned at the outset is accordingly characterized according to the invention by a coding device, in which the provided in each field for the intermediate links Guides along the two selectors are arranged like the types on the type carrier along the two co-ordinates, and by a transmission device from each of the two Switching mechanisms for the type carrier in each of the two selection devices for selecting the one to be driven Intermediate links is displaceable.

It can be seen from this that the already advantageous Code selection device can be controlled in a surprisingly simple manner, since between the Switching mechanisms of the printing unit type carrier and the code selection device no special code or Transfer means must be switched on.

According to an advantageous embodiment of the code selection device, those are arranged in the frame Intermediate links designed as pins that are perpendicular to the common plane of the fields in holes are displaceable and can be replaced individually. This can be done by inserting the pins in the simplest possible way the code key fix and move after remedying.

The invention is described in the description on the basis of, for example, but not restrictively one Embodiment of the invention illustrated drawing explained in more detail. It shows

In Fig. 1 becomes forty-eight after depressing one of 30, not shown in the drawing Push buttons a corresponding lever 4 pivoted clockwise around its shoulder 5 in the trajectory of an attachment 6 of a disk 7

bring to. The forty-eight disks 7 are provided in 35 with a forwardly bent projection 29 ¹ , 29 °, corresponding to twelve different 29 ^ln , 29 ^IV , 29 ^V and 29 ^VI (FIG. 2). In front of the angular positions corresponding to the twelve types of each six lugs 29, a coding device 30 is attached to a type carrier on a splined shaft 8. The orderly, the number of six fields I, II, depressing the button also provides a switching mechanism 9 III, IV, V and VI (Fig. 3), which corresponds to the number corresponding to which the selected types wear 40 of the punch actuators. Each one the type carrier. After the switching mechanism 9 has been set with several in the field of the coding device 30, it is provided together with a row and column arranged elements, corresponding type carrier actuator 11, which the coding device 30 consists of a location with the help of a pin 10 is connected to it, fixed box that moves from a front panel 31 and backwards. The type carrier 45 moved in this way is made of a rear plate 32, which in each actuating member 11 comes into engagement in this way with field I to VI with several spaces or bores of a universal rod 12 which are provided on a 33, which are in four vertical columns A, B, adjustment means, such as one around a fixed C, D, namely one for each type carrier of the vertical axis 14 pivotable switching mechanism 13 loading pressure mechanism, and is fixed in twelve horizontal ones. Normally, the switching mechanism 13 5 ° lines 1 to 12, one for each type each by a spring 15 with a shoulder 16 of a Ver type carrier, are arranged. Adjusting means, such as one on the axis 14 The guides 33 of the coding device 30

Each bore 33 can move forward and backward an insert that can be selected from one piece 55 with it, which, for example, accommodates a displaceable stop extension 22 in the transverse pin 34 as an intermediate member, as a result of which current trajectory of the common carrier recorded in the holes of the various fields the attachment of the type carrier. menen pens the key combinations of the to

Eventually the depressed key releases a punching character. For example, a printing cycle, during which a main actuation 60 corresponds to the first type of the first type carrier executes a full rotation of the printing mechanism according to the coordinates 1 and A ¹ to Α ^ΎΪ . The shaft 18 pivots by means of ordered holes. The second type of the first of a cam 19, the lever 17, initially in the clock type carrier, corresponds to the six holes arranged in the clockwise direction and then counterclockwise to the clockwise direction 2 and A ¹ to A ^XI. The sense around. When it is pivoted around clockwise, the lever 17 moves in the clockwise direction the common, six ordered holes carrying the set of type carrier actuating elements 11 according to the coordinates 1 and B ¹ to ß ^VI , etc. If the first type of support is in a Cross direction until he is through the first type carrier with the key combination

for example, is rotated in a manner known per se, the corresponding punch is used for punching a hole in the paper strip.

On each of the shafts 23 an arm 24 is attached which is provided with a pin 25, which is normally an inclined edge 26 of a slider 27 touches which is slidable on a pair of stationary Axes 28 is arranged. Each of the sliders is

Mark-space-mark-mark-space-space is to be represented, an intermediate member 34 is inserted into the holes 33 arranged according to the coordinates 1 and A ¹ , A ^m , A ^{lv (see also FIG. 2).} In this context it is irrelevant which is the real character of the first type of the first type carrier, since the relationship between the forty-eight characters controlled by the four type carrier actuating members 11 and the forty-eight six-digit key combinations that can be represented by the coding device 30 can be set up as desired.

The intermediate members 34 are through the bent extension 29 of the sliders 27 in their normal Position according to FIG. 1 and 2 held. A transmission device is located in front of the coding device 30 35 (Fig. 2), one of these devices, for example the transmission device, correspondingly the data to be punched can be changed in one plane across the other device can. The transmission device 35 consists of a pair of arms 36, 37 on one on one Pair of side frames 39 and 40 of the machine transversely displaceable shaft 38 are attached. Normally the arm 36 touches the side frame 39 laterally under the action of the force of a spring 41. The arm 37 is connected to the arm 42 of the switching mechanism 13 by a sliding guide.

The transfer device 35 also includes a pair of levers 43 connected to the arms 36,37 and attached to a pivot rod consisting of a horizontal transverse shaft 44, which is provided with six pins 45 (Fig. 2) which are so far apart that they are opposite to the corresponding holes 33 of the adjacent fields are located. The shaft 44 engages in a vertical one Slot 46 (Fig. 1) of a slider arranged displaceably on two stationary pins 46 47 a.

The slider 47 is provided with a pin 50, in which a normally attached to one in 53 pivotable lever 52 hinged hook 51 engages. The lever 52 is under the action of a Spring so that it contacts a cam 54 which is mounted on a shaft 55 which is the main shaft of the Is punching device and after pressing the pushbutton for a punching cycle simultaneously with the Main shaft 18 of the printing mechanism can be set in motion.

The hook 31 is spring loaded so that it normally touches a pin 56 of a bracket 57, which is pivotable on the axis 38 between the two arms 36 and 37 of the transmission device 35 is arranged, whereby the bracket 57 is pivoted regardless of the transmission device 35 can be and can be moved transversely to this. The bracket 57 is with a bent neck 58, which cooperates with an extension 59 present on each of the four switching mechanisms 9. On the shoulder 58 there is a notch 60 (Fig. 2) provided, into which an extension selected from the four extensions 59 can penetrate.

Finally, a link 61 pivotable on the lower arm of the lever is guided by a slide with a bent extension 62 of the bracket 63 pivotable on a vertical axis 64 (Fig. 2) tied together. An arm 65 of the bracket 63 is under the action of a spring 66 so that he normally the arm 37 of the transfer device 35 contacts.

The punching device according to the invention works as follows:

As described above, when a push button is depressed, a corresponding one of the four rear derailleurs (Fig. 1) moved backwards, with a corresponding one of the forty-eight levers 4 is pivoted clockwise, and the main shafts 18 and 55 are set in motion. The extension 59 of the moving switching mechanism 9 pivots after Engage in the approach 58 the bracket 57 counterclockwise and releases the hook 51 from the Pin 50. The cam 19 of the shaft 18 pivots the lever 17 clockwise, and the switching mechanism 13 follows the lever 17 until the extension 6 of the disc 7 is pivoted around Lever 4 is stopped according to the depressed button. During the movement of the rear derailleur 13, the arm 42 pivots the transfer device 35 counterclockwise around and descends the shaft 44 a distance equal to the amount of descent of the individual corresponds to the type carrier actuating member 11 engaging in the universal rod 12.

At the same time, the lever 17 moves the link 61 rearward, thereby pivoting around of the bracket 63 counterclockwise (Fig. 2) by the spring 66 allows the force the force of the spring 41 exceeds, causing the transmission device and the bracket 57 to the right (upward in FIG. 2). When the notch 60 of the lug 58, the extension 59 of the moved Switching mechanism 9 reached, the bracket 57 is by the spring 67 at once in a clockwise direction (Fig. 1) returned, and the rightward movement of the transmission device 35 is due to the engagement the notch 60 with the extension 59 stopped. Furthermore, the pin 56 of the bracket 57 is the hook 51 free, which again comes into engagement with the pin 50 of the slider 47.

It is therefore clear that during the revolution of the shaft 18, the transmission device 35 with the help of the member 61 controlled by the adjusting means 17 and with the aid of the member 61 controlled by the switching mechanism 13 Arm 42 is adjusted differently along the dimensions of the coding device 30 to the Pivot shaft 44 to bring against the bores 33 and the pins 34, which correspond to the depressed Key to represent the key combination of the character to be printed, and click on it Way set the coding device according to this character.

After rotating the shaft 55 by about 180 ° the cam 54 pivots the lever 52 clockwise. The hook 51 pushes the hook Lever 52 moves the slider 47 backwards, whereby the pin shaft 44 with its six pins 45 against which the key combination to be punched representing intermediate links 34 sets and this after backwards. The displaced intermediate members 34 are in turn set against the approaches 29 of the corresponding fields by sliding the corresponding sliding pieces 27 backwards. the inclined edge 26 of each slider 27 displaced in this way now pivots to actuate the corresponding one Punch the corresponding arm 24 with the shaft 23 counterclockwise around.

It is therefore clear that in each field of the coding device 30, the intermediate members 34 individually by the Transmission device 35 after their different adjustment to select the appropriate Punch actuator 23 are individually adjustable.

After the rotation of the shaft 55 has ended, the cam 54 enables the lever to be returned 52 with the hook 51 and the slider 47. The arms 24 are then by their springs and the Sliders 27 fed back through the pin 25, in that they likewise lead back the intermediate links 34. The cam 19 of the shaft in turn leads the lever 17 back, which acts as a switching mechanism 13 in the opposite direction pivots clockwise, causing the arm 42 to pivot the transfer device 35 clockwise pivots around and the trunnion shaft leads up, while the rod 61 returns the bracket 63 and thus allows the transmission device 35 and the trunnion shaft 44 to be operated by the spring 41 to be returned to the left.

If two pushbuttons accidentally pressed down at the same time move two switching mechanisms 9, becomes the bracket 57 after being pivoted counterclockwise is prevented from pivoting clockwise due to the limited transverse dimension of the notch 60 to become, whereby the hook 51 is not released and its subsequent backward movement the coding device 30 is not affected. In this case, an auxiliary slide, not shown, can be used similar to the sliders 27 are provided that the shafts 23 according to the key combination can choose according to the letter spacing. For this purpose, the auxiliary slider are in engagement with a member which is normally connected to the lever 52 which can be actuated by it is connected and can be released from this when the bracket 57 is pivoted clockwise will.

The invention is of course not limited to the exemplary embodiment described and shown limited. You can use numerous, the skilled person according to the intended in each case Apply obvious modifications without thereby departing from the scope of the invention leaves. For example, the hook 51 could both through the bracket 57 and through a either manually or automatically operated member for exclusively punching predetermined ones Data are controlled.
