The problem outlined above is achieved with a Pinch roller arrangement, in particular for a printer, according to the invention in that at least two pinch roller devices arranged to operate in different transverse directions and to selectively move a web in the respective corresponding directions.

The present invention shows one way printers Much simpler and more compact and, for example, can be provided with properties that relate to the Relate compression of printer elements, so that one is practically a desktop printer, one arranged on the wall Printer or the like. Arrives. In addition, the invention lends itself well to a typical iem port printer to simplify by reducing the number of moving parts provided by a typical order of magnitude from several hundred individual parts to one or two dozen individual parts. It is still possible to add about 10 print up to 15 characters per second, inclusive the carriage return time so / ie on commands forward and reverse printing, which is not possible with today's printers. In this way it is possible to reduce the number of moving parts corresponding to one of the order of 15 to 100 Factor to achieve.

Preferably there are two magnetically attractable clamping roller devices provided that the jev / eils along one of two axial directions running transversely to one another are arranged are. .- ■

Each of the clamping roller assemblies can have at least two Pairs of aligned upper and lower pinch roller disks contain. The Scheinerx pairs can be arranged in such a way that

that they come to rest on opposite sides of the web.

In a preferred embodiment, each pinch roller includes at least two offset idler disks and two aligned drive pulleys with drive devices that drive the drive pulleys in the prescribed manner able to turn. Furthermore, magnetization devices provided that allow the drive pulleys to be controlled in such a way that they deliver a sufficient flow to the opposite idler pulleys in the prescribed Way against the web.

trending directions is moved »This serves to to be able to carry out conventional printing operations in a printer device known per se. This is what the railway will do PP corresponding to a prescribed size in the X direction (or in the printing column) moved. To this end, a "nip shift" pinch roller assembly C is activated. This pinch roller arrangement 0 includes a follower arrangement IG - and a cooperating drive arrangement DC. this means that the mutually aligned rollers of these arrangements be moved towards one another in response to a prescribed signal relating to the compression of the rollers. The web PP is in a known manner between the Roller assemblies clamped tightly. The respective rollers can then in one of the arrangements (drive arrangement DO) accordingly a prescribed size (column shift) can be rotated by putting the associated Column motor MG (not shown) and its associated drive shaft SDG. This becomes the relevant Roll by a prescribed "value (corresponding to a associated "column shift" signal, which in itself is supplied in a known manner) rotated. Correspondingly, a line shift can take place in that an analog line shift arrangement L is put into operation which is a follow-up and a drive arrangement Contains IL or DOIi. Those belonging to this arrangement Rolls are on a prescribed (selectively fed) "Line backward" signal in contact with one another. Then the rollers of the drive assembly DCJL by one prescribed value can be rotated, as on a one associated Zeilitfxverschiebe-MQiiai?

running) pinch roller arrangements for the execution of an XY web movement. The movement takes place by shifting a web running between the rollers in transverse directions by controllable values. This feature is particularly useful in providing "column shift" and "line shift ^11" in a printer assembly to be discussed in greater detail below It should be understood that one roller pair or both roller pairs (ie IC-DC, II-DCL, or both) can be brought into engagement in order to also hold a web lying between them in place (e.g. during a printing operation). Furthermore, one or both roller pairs can also be rotated in order to move the web in a corresponding direction (e.g. while the respective other pair of rollers is released). Further details will be apparent from the following description.

In accordance with a further feature, the illustrated pinch roller assemblies can readily be designed for magnetic "self-attraction", v / ie through use a solenoid coil on one of the engageable rollers (or in any other way in which a magnetic flux emanates from the roller, as described in connection with Pig. 14 will be explained later). This pail will the associated roller is designed as "magnetic". According to a related feature, one of these rollers is preferably suitable for this, being very simple and compact and to be stored, such as the light, flexible bearing idler rollers IC, IL can be recognized. About that also contains, as Pig, 1 shows, the gap shift arrangement C a tracking arrangement IC, the one Follow roller with two similar pinch roller wheels 3? -IG,

T'-IC includes, which are attached to an associated idler shaft S-IC. The relevant pinch roller wheels can be rotated with respect to the faces. Said idler shaft S-IO is in turn mounted in the usual way in bearing parts of a flexible bearing arrangement F-IC, which protrudes from a prescribed fixed point on the machine frame in a manner known per se, namely in such a way that the idler wheels £ -10, Q? ¹ -IO assume a prescribed height and are arranged in a manner known per se with the formation of a certain gap to the associated drive wheels T-BO, 3?! - BG of the associated drive arrangement BC, which can be brought into engagement with them.

This Zwiechenräder cleavage is, of course, at least as G ^r OSS "d-ate i- ^ ^{n 3} verifiable manner known per se can be added to a web with a prescribed maximum thickness. The drive arrangement DG thus comprises a drive roller with drive wheels T-DOj T ¹ -DC, which are attached to an associated drive shaft S-DO. The wheels or disks T-DC, T ¹ -DC are made of magnetic material; they are offset from one another at a prescribed distance (and correspondingly the wheels or disks T-IC, T'-IC, which are also aligned with the previously considered wheels or disks). The distance mentioned is at least so large that a lifting magnet coil can be accommodated between the wheels or disks. The coil in question C-DO was arranged so firmly (with respect to a frame) that it surrounds the shaft S-DO between the disks T-DO and T'-DC. In this way, a flux is produced in these disks, which is able to su erseugen a prescribed magnetic attraction flux in a manner known per se in response to a "clamping" command. The drive disks (eB TW ₉ 2J * -DG) can preferably be brought up to the paper web in such a way that they can have contact surfaces with it in a friction-free manner

The idler pulleys or wheels, such as T-IG, T'-IC preferably capable of contacting the web with minimal friction. It will achieved 'that the. Track firmly against the associated drive pulleys or wheels can be guided. The idler disks can be freely rotatable around the moving To be able to "follow" the path with minimal obstruction and a low friction surface. Further the idler disks can be used for steel rollers with a smooth, polished surface or the like. Included.

Fixed coil G-DG surrounding shaft S-DG and creating a flux coupling with the (magnetic) Drive pulleys T-DG and T'-DG are created one of these Slice flowing flux when a prescribed "column interlock" signal is applied to the spool. this happens in a superlative way by the fact that via lines LL, etc., a current pulse is supplied. This magnetic flux is sufficient to make the interacting associated magnetic Idler disks T-IC and T'-IG from disks T-DC and put on T'-DC. In this way, the between the web located on the disks "clamped". Is the corresponding engine (not shown) then a When the "column shift" signal is supplied, the shaft S-DC rotates. As a result, the pinch rollers resting against one another are grounded rotated, to the extent that the between_JLiegende Web moved further in the desired size (in the column direction) will. -

The line shift arrangement L contains tracking and drive devices IL, DCL. She is in a corresponding way

built up. The follower device IL contains two staggered magnetic hit disks Q] -IL and T'-IL, which are mounted on an associated shaft S-IL. This shaft is rotatably mounted in a flexible bearing part F-IL, which is supported by a fixed frame as dep area. P-IC stands away. The drive device DGL contains two magnetic drive pulleys T-DL and T'-DL which are mounted on a shaft S-DL in such a way that they are rotated by the associated motor (not shown). These disks are spaced a sufficiently large distance from one another to be touched by the associated idler disks and to be able to accommodate a non-rotatable lifting magnet coil C-DL between them. This magnetic coil G-DL is magnetically coupled to the disks concerned, specifically in a manner corresponding to the previously considered coil C-DG. The magnet coil in question is thus able ^{to generate an I 1} IuB when it is excited, which attracts the associated idler disks, such as T-IL.

According to a further salient feature, the Column shift and row shift arrangements, respectively controlled by a stepper motor drive device, i.e. by a step-by-step, electrically powered and regulated turning device. Such a one. Establishment is a so-called "slo-syn" motor from the Superior Electric Company. Such a motor is capable of the aforementioned drive pulleys each time to move selectively by a prescribed value. Stepper motors are relatively well suited for use with selectively tightenable pinch roller assemblies, such as the described arrangements in a printer or the like. Arrangement in which the pinch rollers to be determined Points in time are brought into a fixed state, in order to simply "hold" the intermediate track, and at other times put it into operation in such a way that the track is moved in the corresponding direction.

the pinch rollers can be lifted off at still other times to allow the web to move through the other associated pinch roller. Stepper motor ^, like the stepper motor mentioned above, also typically have advantageous properties for the present applications, namely with regard to compact size, low weight, low costs, "reliable operation, direct digital control ( by control pulses without the requirement for. not having a preferred zero position, it should be noted that this is in contrast to conventional servo and synchronous motors, but that such Motox'en are nevertheless used in certain cases instead of stepper motors; or a stepper motor can be added, e.g. as a feedback control for self-testing, etc. .. The use of stepper motors is therefore v on advantage because the rotor torque is small, -. the speed is low and the cost is low. In a device such as the embodiment 2-E shown in Fig. 2, the use of a so-called "slo-syn" motor has been found to be expedient, the following operating characteristics has: a torque of 4-0 to £ 0 inches ounces, relatively high inertia and torque values, a step angle of about 7 to 10 degrees (at about fifty steps per second).

This he :. lon al should be referring to the in iig. 2 generally illustrated printer arrangement 2-E in more detail ^: indlich \, e.den. The printer arrangement shown in FIG. 2 is of the usual type, unless otherwise indicated. Jeuiäi: In FIG Character set disk T is rotatably attached to a Uelle TB. It is located in a prescribed I / aoierebene i ⁵ i ^J in a prescribed pressure position. The shaft TS is mounted in a fixed frame in the usual V / eise; it can be driven to perform rotations are, as by the type disk Hotor TM and the belt drive entered in Fig. 2, in a prescribed, customary V / eise. A conventional coding disk GD with an associated photocell debector DC can also be provided to lift the elements under consideration to decode and display in a manner known per se c.as passing the type set of type ens at ζ disk T. Furthermore, a print hammer is to be operated Transmission arrangement PHA is provided together with its associated magnetic actuator and arranged such that it is able to selectively press a paper area located between its actuating surface and the surface of the type wheel T against the relevant surface of the type wheel T, at times when a selected character passes. This process also takes place in a manner known per se. It goes without saying that color devices can be provided in the usual way in such a printer arrangement. Porous nylon ink ribbon IR is particularly suitable, which is soaked with a colored liquid and which is arranged in a manner known per se so that its colored surface is wiped off the passing surface of the type wheel T when a corresponding rotary movement is carried out.

Although printer 2-E is shown schematically here and some conventional elements are omitted for clarity without losing the understanding of this arrangement, it should be understood that This printer presents a relatively new way of arranging it the printer elements, the associated transport elements, etc. can be recognized. With a corresponding "test embodiment", which is to be referred to as a "roll printer", a printer was developed to serve instead of one heavy printing carriage, as it is done in the usual way, only to move the paper, causing many subsequent still apparent advantages have been achieved. So were ■ E.g. less than twenty moving parts are required here, with comparable known printers of the order of magnitude require from about 500 to 1800 moving parts. It was still a satisfactory high-speed printing operation possible, with about ten to fifteen characters per second, including the carriage return time. In addition, the machine could print in both reverse and forward directions, depending on the information appropriately "stored". Such a printer is thus able to work in a way that other printers working in series operation cannot work. Rather, these must be used when executing a printing process Press the "backward key" twice for each character in the backward direction. In addition, the paper web was "clamped", preventing their movement while pressing was prevented. Printing was done on the fly with a line printer actuator and hammer Conventional construction carried out by a standard connection device with a punched tape or a keyboard is controllable. This per se known Merlanal should in particular make clear the advantage that during the execution of a printing process a corresponding

printing piece of paper can be held and that then the paper in question with very little delay can be switched quickly to the next layer, with the same pressure rollers.

According to further features, one or both of the pinch roller assemblies include a multi-disc construction. Each pinch roller shaft carries two or more disks which are spaced apart from one another and which can be brought into contact with associated disks in the manner described above. Thus, two or more groups of pinch roller / disk combinations (hit running disk - drive disk -) which are in engagement with one another can be aligned with one another along a certain angle and spaced from one another. In addition, the respective pinch roller-disk assemblies are able to cooperate while gripping or moving a web located between them. The exemplary embodiments illustrated in FIGS. 1 and 2 naturally illustrate one form of this feature. According to I ⁿ ig. 1 and 2, the "column shift" and "line shift" pinch roller arrangements are provided, each of which has such pairs of disks which can be brought into contact with one another and which are, for example, spaced from one another in order to accommodate the magnetic coil between them on the drive roller can. Such a multi-disc arrangement is advantageous with regard to the aforementioned stepping motor insofar as a plurality of contact points is achieved between the pinch rollers and the web. This arrangement has the effect, for example, that paper webs are detected much more reliably, are moved better in one direction and are better aligned without skewing. The effect of the clamping caused by the magnet control is shown in .Fig. 2 printer arrangement ZE shown as'derart v / ineffective determined that an excitation of both magnets Uin the

In some cases it will of course be advantageous to use more than two pairs of in-line pinch roller disc assemblies in order, as the embodiments 12-E and 14-E to be considered below, show a stronger pull to achieve over a larger paper width. Another advantage of such multi-disk Klermawalzen with disks spaced apart from each other is that a magnetic coil can be arranged between the disks on a common Uelle, as has already been explained above. Furthermore, both pairs of two-acheibigen pinch rollers can be inserted crosswise into one another in the manner indicated in FIG. 2. It should be understood that if such an "insertion" is possible, a very compact pinch roller assembly is obtained. In addition, the clamping rollers can be brought into such a position that the two pickling axes (gap displacement and line displacement axes) intersect at a common point. A disadvantage may be that in the event that the drive rollers are magnetized by a magnetic coil (as in FIG Anj .. orders of the lower V / alze) changed.

According to a further feature, the pinch roller drive arrangement can contain a single common drive device in which a 90 ° unilinking link is provided between the individual arrangements. This means that instead of in the embodiments according to Eig. 1 to U- indicated separate column shift and row shift step-.

motors, a single stepping motor (or the like) can be used to drive one of the pinch roller arrangements directly and the other indirectly via suitable coupling lines. The use of a single stepper motor can also be of further benefit in certain Italy. As with the one in 'Fi:,. 5 indicated embodiment cfo-Ta V-ü, a single stepping motor VH of the type mentioned above can be used to rotate the drive shaft VS in a controlled manner. The (line shift) arrangement contains a drive shaft V-.d in the same way as the drive arrangement DG in the embodiment 2-E considered above. The drive shaft V-DR can of course drive the associated hit roll, for example when the associated magnet VG is excited. Also shown schematically in FIG. 5 is a column shift drive shaft arrangement V-DR '. This drive shaft arrangement V-DR 'is attached to a corresponding shaft VS' which is rotatably mounted on a fixed frame, not shown here. The drive shaft arrangement V-DR 'is arranged below the shaft VS; it can be brought into contact selectively with its associated idler roller upon excitation of the associated magnetic coil VC.

The drive shafts VS and VS ¹ contain a transverse coupling element VD / V-D 'which is attached to the two shafts and is formed by two friction disks which are coupled to one another. As a result, the rotation of the shaft VS and the clutch VD attached to it caused by the motor VM can cause, in a manner known per se, ^{a synchronous rotation of the other clutch part VD 'and thus the shaft VS 1 and the pinch roller arrangement attached to it.} It should be understood that instead of the coupling arrangement VD / VD 'just considered, a belt coupling can also be used, such as a twisted timing belt (the one in most

9098Λ8 / 0696

Cases preferred) or a "0" strap. In addition, a gear clutch, such as a worm gear or a bevel gear, a friction ball disc drive (such as with a rubber disc), a x'la-rivet drive or the like can also be used. The two shafts VS and VS ¹ always rotate synchronously. Their relative speeds can differ from one another. For example, the transmission ratio from one shaft to the other can be changed by changing the coupling, for example by introducing different transmission ratios, etc. Urn ζ. B. to move a column of a paper web, the solenoid VG is energized. As a result, the column shifting drive shaft V-DR touches its associated idler disks. Then the motor VM is energized, whereby it performs a prescribed step movement. Then, if desired, a line shift can be carried out by releasing the column shift idler disks again and bringing the line shift drive shaft V-DR ¹ into contact with its associated idler disks. This is done by exciting the associated magnet coil YC. As a result, energization of the motor VM causes these rollers to rotate a prescribed step size. The movement is transmitted via the coupling elements VD and V-D '.

It should be understood that the saving of a motor and associated operating devices, control devices, etc., as well as the space savings, the cost savings, etc. despite the disadvantages that may be associated with such a modification, the additional use of the considered Justify the coupling device and the acceptance of certain local restrictions.

Be considered to be the type with an electromechanical / knife and a position control disc is provided, which preferably contains a large number of spacing tracks, like 10 per 25 / 1- mm in the horizontal direction and 6 per ' 25.4 mm in the vertical direction. This could result in very high Rotational speeds for the "carriage return" and high paper advance speeds at relatively low speeds Costs can be achieved.

According to an optimization feature, certain elements of the crossing pinch rollers, like the pinch rollers considered above, are readily made of plastics will. This results in more expedient arrangements with extended costs, etc. As in i'ig. 6 shown schematically, For example, certain elements of an exemplary idler / drive shaft group (6-1, 6 - D) can be designed in this way be that they match the previously considered pinch roller groups correspond. Only those elements are excluded from this that are specifically pointed out. this means that the middle roller 6-1 is a pair of each other spaced plastic hubs 6-6 that may comprise a fixed Hitlaufwelle 6-7 are fastened e.g. by a press fit. The idler shaft 6-7 can, for example, be a metal pipe be. The arrangement can also be made in this way be that the plastic hubs 6-6 have a tubular magnetic Be able to accommodate sleeve 6-5. Seal the honeycombs 6-6 the opposite ends of the sleeve 6-5, and they can also be used as bearing surfaces for the sleeve rotation to act. The Ilaben 6-6 can be made from "Hylon", "Delrin" or consist of a corresponding bearing plastic; they should The conditions that exist in many applications are sufficient, since they are only minor in the arrangement under consideration Are exposed to loads. These loads result either from the weight of the idler elements or from the weight of the spring-loaded shaft 6-7 or by the

These rollers are aligned with their associated drive pulleys in such a way that they can be selectively brought up to them. This takes place in each case in response to an excitation of the associated magnetic coil, which is arranged on the corresponding drive roller located below the area 1-jfL.

and av: ar Especially those associated with the new arrangement of the Hatte 1-rL on top of a compact printer IL as chine. Of course, it can be preferred in: Difference from some of the cases shown, to arrange a vp disk above the leaf, eg fLh? a clearer pressure. With regard to the compact and convenient accommodation of these elements in the printer 1-E, the fact that this machine has the following dimensions should be evident: overall height about 4-5 cm and side dimensions of about 30 cm by 60 cm. The dimensions of the plate surface 1-PL are of course of a corresponding size in order to be able to accommodate sheets 1-P with the maximum possible length. The width of the plate is twice the maximum width of the sheets. This means that there is a plate that is "twice as wide" as the sheets, so that they can be moved across the plate 1-P in the column direction G-C over their entire width. The hammer stop device loads here over the plate 1-PL, namely at least over the entire width of a sheet occurring with the maximum considered width. The sheets can of course easily be inserted manually into such a printer. Only the mechanical components are housed in the designated printer; the feed and linking elements are housed in some other place, such as in an associated data processing system.

It should be noted that this embodiment too compactness of many elements, such as the arrangement of "crossing" pinch rollers with in the boom arm The entire printer is included so designed that a real desktop printer

is present, which is able to easily carry out printing operations on a cover-side plate in the specified manner. The paper 1-P can of course protrude beyond the outer edge of the plate 1-PL if at the end one Ropes are printed on this sheet of paper. Such a "desktop" printer can be used as a remote connection printer in one Data processing system or be used in other advantageous arrangements. The advantageous "composition" the printer elements should be evident. The paper transport is kept simple; he works straight Forward direction and is advantageously arranged above and below the plate. Everyone is there heavy motors, reel-roller assemblies, type disks, etc. below the plate in the lower part of the housing 1-G housed. Only a minimum of required pressure and transport elements are accommodated in the extension arm 1-A, such as the light, flexibly arranged, magnetically attractable idler rollers 1C, 1L. How the Printer 1-E should be apparent in itselfj it runs in the way considered above. ifenÄen e.g. "clamp signals" for .Ercitation of the solenoid coils, which may Drive shafts are arranged around, the pinch rollers 1G and 1L are attracted and brought up to the paper. This is done, for example, by pressing a key on the control keys of the keypad 1-CT "and thus a current here coil lines not shown is supplied. The sheet of paper in question can be selectively held in this way (e.g. for a printing process) or transported further.

While the previously considered embodiment 1-E has illustrated an advantageous technique, the ^ according to transport and printing elements can be arranged and combined in printer and corresponding marking devices, there are further advantages with the embodiments 7-E, 9-E, 12-E and 14-E to be described below according to '""

7 to 13. These embodiments illustrate . e.g., other advantageous arrangements of the crossed pinch roller paper advance elements as well as the associated printing / transport elements. In addition, illustrate the "relevant Forms of execution for other related systems Delivery and processing of paper webs, either in the form of sheets (or corresponding non-continuous sheets) or as endless paper webs wound on a take-up reel. Accordingly, it should be seen that the novel paper transport and associated printing elements in accordance with the invention a new degree of freedom with regard to the delivery and processing of paper material of widely varying widths and bring lengths with them. While embodiment 1-E considered above illustrates an advantageous application has, in which certain transport and printing elements are housed in a cantilever arm, which extends over the paper plate hinv / eg, but should other ways of achieving this this merlanais can be seen, as it is in the embodiment 12-E, which is considered in more detail below be clarified. Furthermore, a somewhat different, but here still associated assembly arrangement will be considered in more detail below, in which the printing and Transport elements are housed in a structure that runs above the paper plate and the shape of an overhanging Rod has, as the embodiments 7-E or 9-E illustrate.

Embodiment 7-E shown in Figs. 7 and 8 represents a console printer containing a housing 7-E with an upper curved plate surface 7-PL, the paper webs able to absorb. There is also a "protruding cross member" housing 7-B arranged above the plate. This housing 7-B accommodates key elements as well as part of the pressure transport elements on, and most in the same way as the one at

909848/0695

Extension arm 1-A provided for embodiment 1-E, but slightly modified. The cross member 7-B is of course carried relatively firmly on both sides, through the housing 7-C. In ν ort hastily ei "Wei se, the cross member forms an upper control panel, such as for the keypad 7-K or the like, and it also surrounds certain pressure elements. This means that the cross member 7-B, the hammer actuator assembly 7-H , which surrounds the j? arbbandwalzen 7-rr and the transport idler rollers, ie the roller 7-LI for the row shift "and the roller 7'-GZ for the column shift. These and other elements correspond to the elements provided for the designs considered above, unless otherwise stated. The housing 7-C, on the other hand, surrounds the remaining print transport elements, namely a type wheel 7- '£ and its associated motor 7-TM and a coding element 7-CC. Furthermore, the housing 7-C surrounds a column shift motor 7-CM with trains - »- Höriger V / alze 7-CD (with solenoid coil for contact with the corresponding idler roller 7-Cl), etc. and a line shift -Motor 7-'IM with the associated drive roller which cooperates with the idler roller 7-ΙΊ. These elements act essentially in the same way as the elements provided in the previously considered embodiment 1-E. A particular advantage of this console printer is that an input / output connection is provided for a communication connection with a central data processing system In this way, with the aid of the printer in the usual way supplied data signals and transport control signals can be produced in a known manner, ie in form of printed sheets 7-P. The keyboard 7-K is designed in the usual way; ucking process on this Eonsol as well as for establishing a data connection with the central data processing device - serve.

Fig. 9, 10 and Ή show relatively schematically a continuously working printer 9-E. This 9-E printer can be used as a free-standing, Remote printer device working with its own feed is considered v / earth, in contrast to known Embodiments has sufficient housing space to house its own power supply units, connection blocks, etc. (in the area 9-GL of the printer frame). One feature This embodiment consists in the fact that most of the printer transport elements are placed in a cross member. Housing compartment 9-B are included, which corresponds in certain respects to the cross member 7-B in the embodiment 7-E, but fulfills another task, namely to accommodate the majority (and not the least part) of the elements. The housing 9-B can be designed to be movable, so that it can be "swiveled out" on the printer frame and thus access to both the paper and the work elements in the housing 9-B. These elements are arranged in such a way that they extend over the "iäbppeltibreite" Web support plate, 9-EL extend and the paper web 9 - P in. two directions, namely in an X direction and in one Y-direction (columns and rows), transport over the plate 9-Hj. Accordingly, only a small number of Druclc- and transport elements, such as the hammer actuator assembly 9-Ξ and the idler rollers, here below the ! 'latte 9-KL to be arranged. This means that purely such elements are needed below the plate, which the transport parts and the pressure point within the cross member Set 9-B. The ribbon rollers 9-E and the associated Ribbons are arranged in a slightly different way here. However, the other elements in the housing 9-B can be used in the Be constructed in essentially the same way and work in the same way as the corresponding elements in the previous ones considered embodiments. The elements concerned are the same as each other unless otherwise specified. .

BATH ORIGINAL

The cross member 9-B surrounds a character wheel 9-T and its associated drive motor 9-Wl as well as a line shift "motor 3-lM with associated drive roller 9-LD and a column shift motor 9-CM with associated drive roller 9-CD Elements are elements that were previously arranged in the machine base.

There is another characteristic of Embodiment 9-E in the way in which the continuous forms

"are supplied and processed in such a way that they are divided into two Directions can be transported (corresponding to a column shift and a row shift as in the earlier embodiments). This is a somewhat unusual measure when printing continuous Forms made use of. Referring to Figure 10, an "endless paper dispensing roller" is shown schematically (where "it is essentially a sectional side view of printer 9-E acts); paper is taken from a supply reel 9-SR continuously unwound and passed over the plate 9-L, as indicated by the arrow entered. this means that both a line shift and a

ι column shift in the transverse direction by the "crossed" pinch roller arrangements is made.'Eine a long intermediate web loop 9-PF is achieved by conventional devices, such as with the aid of a drive motor that rotates the spool 9-SR and which is controlled so that a loop of a certain length is obtained, as is common practice in magnetic recording technology with regard to magnetic tape dispensing systems. It should be apparent that such a paper feed must be able to perform a sufficiently wide unimpeded lateral movement over the plate 9-PL (column shift). The plate 9-I ¹ L must be "twice as wide", ie a sufficient one

909848/0695

192.5-824

Have width to accommodate the respective form and to be able to take into account at least twice the width of the largest form width to be expected. Another paper dispensing arrangement is provided in FIG. 11, in which the formular 9-SS are folded together like a fan. These "formulas" can, as indicated, be passed over the plate 9-PL and put together again on the opposite side, ie in the indicated stack 9-PS. Here, too, a "loop" 9-S ¹ F can be obtained v; For this purpose, customary Itormular pulling and control devices (not shown here) are used.

In Figs. 8 and 8A, large size paper is printer / curve- *. Schreiber 12-E illustrated some of the characteristics of others is.uaführungsformen, such as the cantilever arm of the execution i form 1-E and the "double wide" panel according to the embodiment 9-E along with other new features. These new features include a new sliding one Paper reel dispenser assembly and a new elongated, multi-disc roll feed assembly. The curve recorder 12-E can be understood as a device that, unless otherwise sawn, in the appropriate Is constructed like the previously considered embodiments and also in a corresponding way how this works. The plotter 12-E includes a housing 12-G with a "Introductory" area 12-00 and a '! Double-wide' plate 12-PL. A piece of drawing paper 12-P prescribed width, with the help of a modified embodiment of the invention "crossed" pinch roller arrangement. There are also certain Elements of the pressure-Z-column-shift-elements below the plate 12-PL housed centrally, as shown in Fig. is indicated. Others interacting with these elements Elements are housed in a cantilever arm housing 12-A,

which extends over the print and column shift point '"■; -s- ■ - in the manner as it was previously considered with regard to the Δύε-casual arm structures. Here lies.' On the other (output) side of the plate 12-PIf is a paper tray 12-00 which corresponds to the input tray 12-CG, although typically there is no transport arrangement such as spools A column displacement I-iotor 12-CH and its associated drive shaft 12-CD are arranged below the plate PL, and indeed together with a pressure hammer actuation device 12-h. a are arranged, the complementary elements, namely, a type wheel motor 12 DM with associated driven print wheel and a coding apparatus 12-TC and an effective disposed l arbbandwalze 12-R (which is substantially the roller IR in the embodiment ^{ingeniously;?} Eig . 2 corresponds) and a hit run roller, which can be brought to rest on the column shifting V / alze 12-CD. These elements of course work in the same way as the corresponding elements in the previous b considered execution forines. ·

In some respects the paper dispensing arrangement according to IPig. 9 and 10 corresponding paper dispensing assembly is here however modified in such a way that a document of limited length in 3? form of a relatively long, but not coiled Lane 12-P is delivered. Path 12-P corresponds to the path shown in Figure 8A; she can in that Entry compartment 12-CC initially loose (for a reel 12-PC) be wound, in such a way that the markable area extends under arm 12-A. The web in question is arranged so that they over the plate 12-PL away transported and introduced into the output tray 12-00 can. The lane-12-P is preferably derax ^ t into the.

legend output coil 12-PC) is wound but can still be shifted in the column direction (column shiftability). It should thus be evident that a relatively long document, as is typically the case with in a chart recorder is desired with the help of this Arrangement can be processed in a relatively convenient manner. The document in question receives the freedom of transport possessed by a single document, such as sheet 1-P shown in Fig. 3. In addition, it is rolled up or folded in a zigzag shape endless paper according to FIGS. 10 and 11 added. Here, for example, it should be taken into account that a typical track 12-P about two feet wide and one Has a length of about 90 cm. With those so inevitably led Parallel edges of the sheet, this is automatically in tubular areas within compartments 12-00 and 12-00 wound. The total height of the chart recorder 12-E is thus greatly reduced and its structure is greatly simplified. The reason for this is, for example, that it is not necessary to have an introductory or discharge device to proceed.

In accordance with a further feature is the line-wrapping pinch roller assembly modified so that such a paper web can be accommodated. Furthermore, the railway operating regulations slightly offset from where the column shift arrangement is located. This means, that these V-roller pairs in the area or compartment 12-OG are housed and contain an elongated shaft 12-LS, which by an associated engine 12-LH with a variety of associated with this, successive at regular intervals Drive rollers 12-L1, 12-L2, 12-IjJ, "etc" can be driven in a controlled manner, namely under the Paper plane in the way it is with respect to the drive rollers DG explained above in the arrangement according to FIG. 2

has been. In addition, a set of correspondingly aligned idler rollers 12-L'1, 12-L'2, 12-L'3 is provided. The line shift arrangement, like the above embodiments, may preferably include magnetic attraction means for selective roller clamping. The elongated line shifting arrangement of the pinch rollers is thus positioned across the "paper web", i.e. past the point of possible movement of the paper as it is drawn away from the spool 12-PC over the platen 12-PL. The arrangement is also made such that a column shift "te (as in the embodiment 9-E) is possible via a the" Ibρρelten the maximum form width corresponding Durchgangsbrei. The complementary idler rollers 12-L1 ^1, etc. are of course spaced apart and aligned with each of the above drive rollers so that with paper form passed between these rollers, the pairs of pinch rollers can be attracted magnetically or otherwise, as explained in connection with the above embodiments. Rotation of shaft 12-LS The idler rollers or disks 12-L1 ¹ , etc. can expediently be flexibly hinged to the top of the compartment 12-GC in the usual way, but they can also be hinged to any other Be arranged in a known manner.,

It should be seen that these characteristics lead to a unique device, namely to a printer / chart recorder. This arrangement can include cards, drawings, Deliver lists, diagrams and graphs on large sheets of paper. The arrangements are designed so that the paper in a unique ^ advantageous Way is treated and transported. Furthermore is a

Furthermore, can the compartment or area 14-CC, the printer and paper transport elements take up, essentially in the manner as it has been shown in the embodiment 12-Ξ is. Accordingly, a prescribed length of the paper web 14-P in loosely folded form (indicated as a coil 14-PG) in a tubular receiving area or in a tubular receiving compartment 14-GG are introduced. the The paper web can be freely moved laterally (for column shifting). With the behind the printer and Transport elements extending initial web length, the web can be printed or otherwise marked and (for printing a Line) can be transported sideways step by step.

These Display panel 14-B has twice the maximum width of the SOrmuTares corresponding width, like the embodiment 12-E. Furthermore, the arrangement can "shift lines" - ! Execute the function in the same way as the one explained above Embodiment 12-E. On the ^ other side of the "Paper path" are the other transport and printing elements that interact with the elements explained, namely a print hammer actuator assembly 14-h, which cooperates with the type wheel 14-T, a column shift motor 14 — GM with associated drive roller 14 — GD, the with the aforementioned column shift idler roller opposite it is contactable, and a line shift motor 14-LM with an associated set of drive rollers 14-LD on a shaft 14-LS.
