The portable computer is described below using a notebook. The notebook according to FIGS. 1 to 3 has a housing 1 having a rectangular outline. It accommodates the most diverse components of a notebook in a known manner, such as the processor, the motherboard, memory chips, a graphics card, at least one hard disk, a floppy disk drive, a CD-ROM drive, a CD burner and the like. Interfaces of the most varied types can be provided in a known manner on the housing 1 , preferably on its rear side, but also on its two narrow sides. At the rear longitudinal edge 2 of the housing 1 , a screen 3 is articulated, which can be adjusted and locked in a known manner down into a position closing the notebook. It is understood that the screen is part of a cover with which the notebook can be closed in a known manner. If the screen 3 is opened ( FIG. 1), then it releases an alphanumeric keyboard 4 which can contain any additional keys, for example for fast access to the Internet, for e-mails and the like. The keyboard 4 is part of a module 5 , which is removably arranged on the housing 1 . The module 5 also has a rectangular outline, but is smaller than the housing 1 ( FIG. 1). The keyboard 4 is provided on the top of the module 5 . The opposite underside 6 of the module 5 is designed as a graphics tablet on which a pen can be used to write, for example, to make drawings and the like. The electrical and / or electronic components required for the graphics tablet are accommodated in module 5 . It has at least one interface 7 ( FIG. 3) which interacts with a corresponding (not shown) interface of the notebook and serves to send the signals triggered by the keyboard to the processor housed in the housing 1 so that it can evaluate the signals accordingly , The module 5 is also provided with at least one interface 8 which interacts with a corresponding (not shown) interface of the notebook. Via the interface 8 , the signals that are triggered when working with the pen on the graphics tablet 6 are fed to the processor in the housing 1 , which evaluates them accordingly.

The module 5 is secured with detachable fastening elements 9 in the housing 1 . The fastening elements 9 can be latching, plug-in, clamping elements, such as clips.

Fig. 1 shows the notebook with the screen 3 unfolded, which is connected in a known manner to the electronics housed in the housing 1 , in particular to the processor and to the graphics card or the graphics chip. With the keyboard 4 , the inputs can be made in a conventional manner.

As is apparent from Fig. 2, the housing 1 is provided with a recess into which the module 5 may be employed. As a result, the module 5 does not protrude beyond the housing 1 , so that the notebook can be worked comfortably.

For example, to drawings will be made, the retaining elements 9 are loosened, the module 5 removed from the housing 1, rotated 180 ° again inserted and secured with the holding elements 9 in the housing. 1 Now the graphics tablet 6 is on top, so that the drawings can be easily made with an appropriate pen. The interface 8 for the graphics tablet 6 is advantageously designed such that when the module 5 is inserted into the housing 1, the interfaces in the graphics tablet and in the notebook are inevitably brought together. The notebook is advantageously designed so that the module 5 can be removed during operation of the notebook and inserted in the new position in the housing 1 . This so-called hot docking technology is known in notebooks, for example when using PC cards, so that it is not explained in more detail here. The inputs generated on the graphics tablet 6 are displayed on the screen 3 .

The interface 7 for the keyboard 4 is designed so that when the module 5 is inserted into the housing 1, the interfaces of the notebook and module 5 are inevitably merged, so that the keyboard 4 can be continued immediately after the module 5 is inserted.

Instead of the mechanically interacting interfaces, it is of course also possible to carry out the data and signal transmission between the module 5 and the notebook wirelessly, for example via radio. In this case, mechanical interfaces are not necessary.

In one embodiment (not shown), it is also possible to provide the module 5 with a cable so that it can be connected to a conventional PC. The cable can be firmly connected to the module 5 . But it is also possible to provide the module 5 with a connection for the cable, so that it can be connected to the PC after removal from the notebook via the cable now to be connected. Instead of the cable, data and signal transmission to the PC can also take place wirelessly, for example via radio or infrared. In this case, the module is equipped with an appropriate transmitter that sends radio signals or infrared signals to the PC. Module 5 can thus be used either with a notebook or with a conventional PC.

It is possible to accommodate a storage medium, for example a small hard disk, in the module 5 , on which files created using the keyboard 4 or the graphics tablet 6 can be stored. If the module 5 is connected to a PC in the manner described, the data stored in this storage medium can be transmitted to the PC via cable or wirelessly.

In the embodiment according to FIG. 4, the module 5 is provided with a only the keyboard 4 a, while the graphic tablet is provided a 6 a of the notebook on the housing 1 below the module 5 a. In order to be able to work with the graphics tablet 6 a, the module 5 a only has to be removed. The module 5 a is advantageously secured to the notebook in the same way as in the previous embodiment. The module 5 a is merely provided with at least one interface for the keyboard 7a that cooperates with the mating interface 7 a of the housing 1 a. The holding elements 9 a are provided for holding the module 5 a. Otherwise, the notebook according to FIG. 4 has the same design as the exemplary embodiment according to FIGS. 1 to 3.

Module 5 a can also work wirelessly, for example by radio or infrared, with the notebook. In this case, the mechanical interface 7 a is not necessary. The module 5 a can also interact with a conventional PC wirelessly, for example via radio or infrared, or via a cable, as has been described with reference to the previous embodiment.

In the embodiment of Fig. 5, the module 5 is provided with the graphics tablet b 6 b, while the keyboard 4 b is provided on the notebook. In this case, to work with the keyboard 4 b, it is necessary to remove the module 5 b in order to make the keyboard 4 b accessible. The module 5 b is provided with the interface 8 b in order to connect the graphics tablet 6 b to the corresponding interface of the notebook. As in the previous embodiments, the module 5 b is held and secured in the notebook by means of the holding elements 9 b.

Instead of the mechanical interface 8 b, the module 5 b can also work wirelessly with the electronic components housed in the housing 1 b in order to pass on the signals generated when working with the graphics tablet 6 b to the notebook.

The module 5 b can advantageously be connected to a PC by cable or wirelessly when it is removed from the notebook. Then b on the tablet 6 entered data can be stored in the PC and / or displayed on the monitor.

The module 5 b can be provided on its underside with fold-out feet, so that it can be tilted on a corresponding support, so that a particularly simple and fatigue-free work on the graphics tablet 6 b is possible. In the same way, the module 5 a can also be provided on its underside with corresponding fold-out feet.

The module 5 according to FIGS. 1 to 4 can be provided with fold-out feet on both sides, so that the module 5 can be tilted, regardless of whether the keyboard 4 or the graphics tablet 6 is to be used.

In the embodiment according to FIG. 6, the notebook has no mechanical keyboard. Instead of such a keyboard, the graphics tablet 6 c is used, in the work surface of which the keyboard or other keys are shown. They can then be operated with your finger or a special pen. The switch from the keyboard to the graphics tablet function can be carried out by switches provided on the housing 1 c of the notebook. It is also possible to display a menu in the graphics tablet which has corresponding keypads with which it is possible to switch from keyboard operation to graphics tablet operation. With such a design, the graphics tablet 6 c need not be designed to be removable, but can be accommodated in the housing 1 c. However, it is of course possible to provide the graphics tablet 6 c on a removable module which can then be held and secured in the housing 1 c in the same way as in the previous embodiments. This module can then advantageously also be connected to a PC by cable or wirelessly.

The entries made on the graphics tablet 6 c are shown on the screen 3 c of the notebook.

If the graphics tablet 6 c is provided on a removable module, then this can be designed in accordance with the previous embodiments.

Since the keyboard can be faded into the graphics tablet 6 c, it is possible, for example, to display keyboard layouts for a wide variety of languages, for example Arabic, Cyrillic, Japanese or Chinese, or also for mathematical characters, special characters and the like. The selection of the keyboard layout to be displayed is determined by the user. Appropriate fields of activity can be displayed in the graphics tablet for selection.

In the embodiments according to FIGS. 4 and 5, when the module 5 a, 5 b is removed, the keyboard 4 a, 4 b and the graphics tablet 6 a, 6 b can be operated optionally without a changeover being necessary. This ensures very simple working, since the user of the notebook can, for example, make a drawing on the graphics tablet 6 a, 6 b and, if necessary, use characters with the keyboard 4 a, 4 b as required. The user of the notebook only has to switch between the graphics tablet and the keyboard to make the necessary entries. On the screen 3 a, 3 b can control the entries immediately.

The notebook according to Fig. 7 has the screen of the previous embodiments is pivotably d about the axis 10 at the longitudinal edge of the housing 1 3 d accordingly. The module 5 d is pivotally mounted in the notebook, preferably also on the same longitudinal edge of the housing 1 d as the screen 3 d. In the rest position, the module 5 d lies on the housing 1 d and covers the keyboard 4 d, which is provided on the housing. The module 5 d advantageously has the same outline as the housing 1 d. On the side facing away from the keyboard 4 d, the module 5 d is provided with the graphics tablet 6 d, on which 3 d can be worked after the screen has been folded up. The entries on the graphics tablet 6 d are displayed on the screen 3 d.

It is advantageous to secure the module 5 d in the folded-down position on the housing 1 d, for example with clips and the like.

The module 5 d can be pivoted from the folded position into a folded-up position in which it rests on the screen 3 d. The keyboard 4 d is then exposed and can be easily operated by the user of the notebook. The entries made with the keyboard 4 d are now shown on a screen 11 which is provided on the side of the module 5 d opposite the graphics tablet 6 d.

Since the module 5 d is pivotally mounted in the notebook, the user can very easily switch the notebook if he wants to switch from keyboard operation to graphics tablet operation. When pivoting the module 5 d from the folded into the unfolded position, it is possible to switch off the hidden screen 3 d, so that only the screen 11 is switched on. This protects the notebook's battery. Conversely, the screen 11 is switched off when the module 5 d is moved from the folded-up to the folded-down position.

The graphics tablet 6 d and the screen 11 can form two separate structural units which are connected to one another to form the module 5 d. The two units 6 d, 11 can have their own housings, so that the electrical and / or electronic components necessary for operating the graphics tablet 6 d and the screen 11 can be accommodated in the housings without any problems. It is of course also possible to use a common housing for the graphics tablet 6 d and the screen 11.

The embodiment according to FIG. 8 differs from the exemplary embodiment according to FIG. 7 only in that the module 5 e has the keyboard 4 e instead of the graphics tablet. The graphics tablet 6 e is provided in the housing 1 e and is covered by the folded-down module 5 e. If the module 5 e has been folded down, the keyboard 4 e can be used to make entries that are visible on the screen 3 e. If the module 5 e is folded up, the screen 3e is covered as in the previous embodiment, so that the user only sees the screen 11 e. The inputs on the graphics tablet 6 a are thus visible on the screen 11 e.

As in the previous embodiment, it is possible, depending on the position of the module 5 e, to switch off the screen 3 e or the screen 11 e in order to extend the battery life of the notebook. Of course, it is possible, even in the previous embodiment, to leave both screens 3 e, 11 e switched on. It is thereby possible that the respective screen content is not changed when the module 5 d, 5 e is folded up and down. It is also possible, however, when the modules 5 d, 5 e are folded up or down, the respective screens 3 d, 11 ; 3 e, 11 e to switch so that the same image can be seen on both screens.

The notebook according to Fig. 9 f has the housing 1, the keyboard 4 is on the f. The screen 3 f is mounted on the longitudinal edge of the housing 1 f in a known manner to pivot about the axis 10 f.

On the back of the screen cover, the graphics tablet 6 f is provided, which preferably has the same outline as the screen cover. If the notebook is closed, the graphics tablet 6 f is easily accessible. Entries can then be made on it in a conventional manner. In accordance with the embodiment according to FIG. 6, the keyboard can be faded into the graphics tablet 6 f, which can be switched on and off with the aid of shift keys which are also faded in. This means that 6 f keystrokes can be made on the graphics tablet even when the notebook is closed.

It is advantageous if the graphics tablet 6 f can be switched on or off by an additional switch, even when the notebook is closed. Such a switch can be located on one of the four sides of the housing 1 f.

The screen 3 f and the graphics tablet 6 f form the module 5 f, which is pivotally mounted about the axis 10 f on the housing 1 f.

The notebook according to FIG. 10 g has the housing 1, the keyboard 4 is on the g. On its rear longitudinal edge, the screen 3 g is pivotally mounted about the axis 10 g according to the previous embodiments. The housing 1 g has an installation space 12 into which the graphics tablet 6 g can be inserted. In the illustrated embodiment, the graphics tablet 6 g is pulled forward from the housing 1 g when it is to be used. It is also possible to arrange the graphics tablet in the housing 1 g so that it can be pulled out to the right or left. It is advantageous to limit the extension path of the graphics tablet 6 g by a stop (not shown). The connection between the graphics tablet 6 g and the notebook 3 g can be made via a cable or wirelessly. If the graphics tablet 6 g is pulled out of the housing 1 g, an automatic changeover takes place in such a way that the inputs on the graphics tablet 6 g are now displayed on the screen 3 g. If the graphics tablet 6 g is pushed back into the housing 1 g, a corresponding change is made so that the keyboard entries are now visible on the screen. But it is also possible to change the screen after pulling out or pushing back the graphics tablet 6 g using a special switch.

In the embodiment of Fig. 11 the tablet 6 can be pulled out completely from the housing h 1 h. The connection to the notebook is then advantageously wireless, for example via radio, infrared and the like. Otherwise, the notebook is of the same design as the exemplary embodiment according to FIG. 10.

FIG. 12 shows a notebook in which an additional keyboard 13 can be pulled out of the housing 1 i laterally. This additional keyboard 13 has, for example, the keys of a calculator. In this way, numerical inputs can be provided very easily, as in a conventional PC, in which the numeric keys on the keyboard are combined in the right part to form a keyboard unit. The additional keyboard 13 can also be provided laterally from the housing 1 i so that it is available to the user of the notebook if required. The additional keyboard 13 is coupled to the notebook so that the keyboard entries are shown on the screen 3 i. Data can be transmitted via cable, an interface or wirelessly. As in the embodiment according to FIG. 10, the interface is advantageously designed and provided on the housing in such a way that the keyboard 13 is only coupled to the notebook via the interface at the end of its extension path.

The additional keyboard 13 can also be removable. It can then be connected to a conventional PC via cable or wirelessly.

The housing 1 i has, in a known manner, the keyboard 41 , with which the entries on the notebook are made in the usual way.

FIGS. 13 to 15 show an embodiment in which the screen 3j can be moved from the opened position according to FIG. 13 to the closed position according to FIG. 15. The usual keyboard 4 j, with which the entries are made, is located on the housing 1 j.

The housing 1 j has on each of its two narrow sides a rail-like guide 14 , along which the screen 3 j can be moved. For this purpose, it is provided at its two lower corners with a slider 15 , which can slide in one of the rail-like guides 14 . In addition, the screen 3 j is articulated on its two narrow sides, each with a support 16 . The two supports are articulated at one end on the rear longitudinal side of the housing 1 j and with their other end approximately in half length on the narrow sides of the screen 3 j.

In the unfolded position ( FIG. 13), the two supports 16 lie approximately at the level of the rear of the screen 3 j, so that they do not protrude over the back of the screen. In this position, the screen 3j is advantageous to the housing 1 j secured, such as with releasable clips or the like. If the screen 3 j is to be moved into the folded-down position according to FIG. 15, the holding parts at the lower corners of the screen 3 j are released. With the slides 15 then the screen 3 can be pivoted j, with j the sliders move toward the front end side of the housing 1 15 °. The screen 3 j pivots counterclockwise and is held by the supports 16 which pivot about its articulation axis on the housing 1 j clockwise. In this way, the screen 3 j remains on top, so that it is visible even when the notebook is closed ( FIG. 15). The outline shape of the screen 3 j corresponds to the outline shape of the housing 1 j, so that it does not protrude over the housing. The supports 16 are so long and articulated laterally on the screen 3 j that they are advantageously parallel to the top and bottom of the notebook when it is closed ( FIG. 15). In the closed position, the screen 3 j hides the keyboard 4 j, so that entries can only be made via the screen 3 j. The graphics tablet 6 j is integrated into the screen 3 j, on which inputs can be made with a special pen.

The screen 3 j can, for example, be divided into two so that the user can use the screen as a graphics tablet 6 j in one part, while the inputs are visible in the other part of the screen.

The notebook according to FIGS. 16 to 18, the module 5 to k, which on the one hand the keyboard 4 and k other on the side having the tablet 6 k. This module 5 k can thus be of the same design as module 5 according to FIGS. 1 to 3. On each of the two opposite narrow sides of module 5 k, one end of a support 17 is articulated, the other end of which is half the width of the housing 1 k is articulated on the notebook. The supports 17 are articulated near the one corner areas of the module 5 k.

Fig. 16 shows the notebook with the screen 3 k unfolded. The module 5 k rests on the housing 1 k so that the keyboard 4 k lies on top. The module 5 k can be designed so that it covers the entire top of the housing 1 k. But it is also possible to design the module 5 k so that it can be accommodated in a recess of the housing 1 k. The supports 17 extend from their articulation point on the module 5 k in the direction of the pivot axis 10 k for the screen 3 k.

In order to be able to work with the graphics tablet 6 k, the module 5 k is lifted from the housing 1 k as far as the supports 17 permit. It is then rotated about the pivot point of the supports 17 by 180 °, the supports 17 being pivoted clockwise into the position shown in FIG. 18, in which the module 5 k rests on the housing 1 k in such a way that the graphics tablet 6 k lies above. In this position, the supports 17 extend from their articulation point on the module 5 k in the direction of the end face of the housing 1 k.

In the two working positions of the 5 k module, it is advantageous to secure the module to the 1 k housing. The module 5 k (not shown) may be provided which cooperate k k depending on the location of the module 5 with corresponding interfaces on the housing 1 interfaces. This ensures that the signals generated by the keyboard 4 k or the graphics tablet 6 k can be processed reliably and the inputs can be displayed on the screen 3 k. The connection can also be made wirelessly, for example via radio.

Figs. 19 to 21 show that the posts may also be hinged near the front of the housing 1 l. In this case, the ends of the supports 17 l are articulated in half width on the narrow sides of the module 5 l.

In the position shown in FIG. 19, the module 5 is l so on to the housing 1 l, the keyboard 4 is l above. In order to be able to work with the graphics tablet 6 l, the module 5 l is lifted from the housing 1 l to such an extent that it can be rotated 180 ° with respect to the supports 17 l. The supports 17 l here move counterclockwise into the position shown in FIG. 21, in which they extend from the end face of the housing 1 l in the direction of the screen 3 l and the graphics tablet 6 l is at the top.

Apart from the different articulation of the module 5 l to the housing 1 l, the notebook is of the same design as the embodiment according to FIGS. 16 to 18.

In the embodiment of Fig. 22, the housing 1 is provided m m with the keyboard 4. The screen 3 m is pivoted 1 m on the rear longitudinal edge of the housing. Similar to the embodiment according to FIG. 10, the graphics tablet can be pulled out 6 m laterally from the housing 1 m. The 1 m housing is provided with a corresponding receiving space for the 6 m graphics tablet. Otherwise, this exemplary embodiment has the same design as the embodiment according to FIG. 10.

Fig. 23 shows the possibility of the notebook with two screens 3 n to 18 is provided. Both screens 3 n are the same size. The screen 3n has the same outline shape as the housing 1 n, so that it completely covers the housing in the folded state. The two screens 3 n, 18 are articulated with their narrow sides facing each other. The screen 18 can therefore be pivoted outward about the axis 19 from an initial position in which it lies in front of the screen 3 n into the position shown in FIG. 23. The screen 18 is then in the area next to the notebook. The second screen 18 has the advantage that the user can work with two screens at the same time without the need for a second notebook and / or a second additional monitor.

The notebook itself can be designed in accordance with one of the preceding embodiments. It is also possible to design at least one screen 3 n and / or 18 as a touch screen such that the keyboard and / or the graphics tablet are shown in it. The keyboard or graphics tablet displayed in this way can be operated in a known manner with a pen or with the fingers.

The embodiment according to FIG. 24 differs from the previous exemplary embodiment only in that the second screen 18 can be folded back to the rear of the screen 30 . Otherwise, this notebook is of the same design as the exemplary embodiment according to FIG. 23.

FIG. 25 shows an embodiment in which the screen 18 p can be pivoted forwards and backwards about the axis 19 p. The pivot axis 19 p lies in the area of one narrow side of the housing 1 p of the notebook.

The notebook according to FIG. 26 has the two screens also q 3, q 18, of which at least the screen 18 q q about the axis 19 is pivotable. In contrast to the embodiments according to FIGS. 23 to 25, the pivot axis 19 q is not stationary, but can be moved along the rear of the housing 1 q. For this purpose, the housing 1 q is provided with a corresponding guide 20 , along which the two screens 3 q, 18 q can be moved together with the pivot axis 19 q. It is thereby possible to design the two screens 3 q, 18 q in the center with respect to the housing 1 q. This gives the user an optimal view of both screens. In addition, the possibility of moving the screens 3 q, 18 q results in the advantage that the notebook has a stable position.

It is possible to limit the displacement of the axis 19 q, so that the two screens 3 q, 18 q can be adjusted very easily to the central position shown in FIG. 26. In this case, it is advantageous if the pivot axis 19 q and / or at least one of the two screens 3 q, 18 q is locked or locked in the central position.

It is also possible to design the guide 20 such that the pivot axis 19 q is displaceable from the one narrow side 21 to the opposite narrow side 22 of the housing 1 q. The two screens 3 q, 18 q can then be adjusted to any desired position along the back of the housing 1 q. In this case too, it is advantageous to secure the pivot axis 19 q at least in the two end positions, for example by latching.

While the two screens 3 q, 18 q are the same size in the embodiments according to FIGS. 23 to 26, the notebook according to FIG. 27 is distinguished by the fact that it has screens of different sizes. The notebook with the housing 1 r has the main screen 3 r, the width of which corresponds to the width of the housing 1 r in accordance with the previous embodiments. An additional screen 18 r, 18 r 'is connected to the side of the screen 3 r, the width of which corresponds to half the width of the screen 3 . The two additional screens 18 r, 18 r 'are each pivoted about an axis 19 r, 19 r' on the narrow sides of the main screen 3 r. The two pivot axes 19 r, 19 r 'lie at the level of the narrow sides 21 r, 22 r of the housing 1 r. The additional screens 18 r, 18 r 'can be folded forward about the axes 19 r, 19 r' in the direction of the arrows on the main screen 3 r when the notebook is to be closed. There is also the possibility of folding the two additional screens 18 r, 18 r 'backwards, so that the user of the notebook only sees the main screen 3 r.

With the notebook it is possible to use only the main screen 3 r or at least one of the additional screens 18 r, 18 r '. Depending on the application, the user has the option of adapting his notebook accordingly. When the additional screens 18 r, 18 r 'are folded out, the corresponding additional screen is expediently switched on, so that it only has to be supplied with power when it is in use. Accordingly, the power supply to the respective additional screen is advantageously switched off when it is folded back.

Since the two additional screens 18 r, 18 r 'are advantageously half as wide as the main screen 3 r, they lie against one another with their long sides in the folded state.

The notebook according to FIG. 28 differs from the notebook according to FIG. 27 only in that the additional screens 18 s, 18 s' are not pivoted, but shifted relative to the main screen 3 s. The two additional screens 18 s, 18 s' can be moved in front of or behind the main screen 3 s. However, it is also possible to design the main screen 3 s in such a way that the additional screens 18 s, 18 s' can be moved into the main screen 3 s. Thus, this notebook also has the option of using only the main screen 3 s or at least one additional screen 18 s, 18 s'.

A motor can be provided for moving the additional screens 18 s, 18 s'. It can be actuated by a key provided on the notebook or also by a button, for example on the screen 3s.

There is also the possibility of locking the additional screens 18 s, 18 s' in the retracted position. This latching is advantageously designed such that, in order to release the latching, the respective additional screen 18 s, 18 s' is first pressed further inward in order to move a latching element into the release position. After releasing this additional screen, at least one compression spring ensures that the respective additional screen is extended 18 s, 18 s'.

It is also possible to provide only an additional screen 18 s or 18 s' on the main screen 3 s, which advantageously has the same width as the housing 1 s. This also applies to the exemplary embodiment according to FIG. 27.

The additional screens 18 r, 18 r 'and 18 s, 18 s' of the embodiments according to FIGS. 27 and 28 are advantageously the same height as the main screen 3 r, 3 s. It is of course possible that at least one additional screen has a different height than the main screen.

FIG. 29 shows an embodiment in which the additional screen 18 t is moved up out of the main screen 3 t. The two screens 3 t, 18 t are advantageously the same width as the housing 1 t of the notebook. The additional screen 18 t can be retracted into the screen 3 t. But it is also possible to store the additional screen 18 t behind the screen 3 t and to provide a corresponding receptacle for it on the back of the screen 3 t. The additional screen 18 t can also be adjusted by motor or manually. In the case of manual adjustment, a detent is again advantageously provided, which is designed such that the detent is released by pressing the retracted additional screen 18 t and the additional screen is moved out into the working position shown in FIG. 29 by at least one spring.

Fig. 30 shows a side view and a greatly simplified representation of a notebook with the housing 1 and the screen 3 u. On the upper longitudinal edge 23 of the screen 3 u, an additional screen 18 u is pivotally mounted about an axis 24 . The additional screen 18 u can be folded out into the position shown in FIG. 30. In this position, the user can view the screen 3 u and a person sitting opposite him can view the screen. In this way, the user of the notebook can use the keyboard or the graphics tablet to make inputs that the person sitting opposite can immediately see on the screen 18u. It is therefore not necessary that the user rotates the notebook after appropriate entries so that the person sitting opposite can view the screen 3 u.

The additional screen 18 u has at its lower longitudinal edge 25 at least one holding element 26 which can cooperate with a corresponding holding element 27 on the lower longitudinal edge of the main screen 3 u when the additional screen 18 u is folded against the back of the main screen 3 u. The holding elements 26 , 27 can, for example, be clips, locking elements, but also magnets, which securely secure the additional screen 18 u in the folded-back position on the back of the screen 3 u.

The pivot axis 24 is designed to be self-locking so that the additional screen 18 can be adjusted and held in any pivot position. The u required for operation of the auxiliary screen 18 lines are routed u in the auxiliary display 18 via the pivot axis 24th Since both screens 3 u, 18 u can be swiveled independently of one another, they can be set independently of one another, for example in the case of mirroring, in such a way that the user or the person sitting opposite can see the screen contents properly.

The notebook according to FIG. 31 differs from the exemplary embodiment according to FIG. 30 only in that a holder 28 is provided for the additional screen 18 v. It is advantageously a frame which is articulated at about half the height of the screen 18 v on its narrow sides. This allows the additional screen 18 to be pivoted relative to the frame 28 about the pivot axis 29 . In this embodiment too, the user of the notebook can view the main screen 3 v and the person sitting opposite can view the additional screen 18 . As in the previous embodiment, the additional screen 18 v is advantageously switched on automatically when it is folded out of the rest position, in which it is held on the back of the main screen 3 v, into the working position. It is of course also possible to separately switch the screen 3 v on and off, as can also be provided for the notebook according to FIG. 30. The two screens 3 v, 18 v can be folded together and folded in this position onto the housing 1 v to close the notebook.

There is also the possibility of moving the additional screen 18 u, 18 v into the main screen 3 u, 3 v. For this purpose, the lid of the notebook is provided with a recording space in which the additional screen 18 u, 18 v can be accommodated in a protected manner. The additional screen 18 u ( Fig. 30) is pivoted up about the axis 2 u so far that it is an extension of the main screen 3 u. Then the additional screen 3 u can be easily moved into the recording space of the main screen 3 u. In the embodiment according to FIG. 31, the additional screen 18 v is moved together with the holder 28 into the receiving space of the main screen 3 v. The additional screens 18 u, 18 v are only pulled from the main screen 3 u, 3 v when necessary and pivoted into the position shown in FIGS. 30 and 31.

With regard to the arrangement and design of the keyboard and the graphics tablet, the notebooks according to FIGS. 23 to 32 can be configured in the same way as the notebooks according to FIGS. 1 to 22.

The additional screens 18 ; 18 o; 18 p; 18 q; 18 r, 18 r '; 18 s, 18 s'; 18 t; 18 u; 18 v can have a touchpad function. In particular in the embodiments according to FIGS. 30 and 31, this has the advantage that the person sitting opposite can make inputs 18 u, 18 v on the additional screen.

The additional screens 18 ; 18 o; 18 p; 18 q; 18 r, 18 r '; 18 s, 18 s'; 18 t; 18 u; 18 v according to FIGS. 23 to 31 can also be provided for TFT screens which are used for normal PCs.
