Abstract

When using the screen (3) of a notebook computer (1) as the display of a primary workstation and in conjunction with a separate keyboard (2), the user (5) of the separate keyboard can be prevented, by the depth of the body portion (4) of the computer from being at the optimum viewing distance from the screen, since it is not possible to get the separate keyboard (2) close enough to the screen. To overcome this, an additional position of the screen relative to the body portion is proposed. In a particular arrangement the screen is rotatable to a position of the order of 270° from the notebook closed position, as well as to the normal open position of the order of 90° from the notebook closed position.

Description

NOTEBOOK COMPUTERS
TECHNICAL FIELD
This invention relates to notebook computers and in particular to notebook computers which, in addition to being usable in the portable, or free-standing, mode, facilitate use in a primary workstation arrangement at a workplace .
BACKGROUND ART
The technological advances in notebook screen technology, in particular the increased screen sizes which have become possible, mean that a notebook's own screen can be used as a primary display at a workstation, instead of for example a CRT monitor or another form of substantially non-portable display. However, the keyboard and mouse solutions of the notebook do not meet the current requirements for primary workstation input devices. When a notebook screen is used in a primary workstation context, external input devices must be used. Thus for example, the notebook computer is opened up in order to be able to view its screen and a separate primary workstation keyboard is employed as illustrated schematically in Figure 1. The keyboard may be connected to the notebook and/or other elements comprising the primary workstation by, for example, cables, infrared links, or the like. However, when the separate keyboard is disposed in front of the notebook in this manner, the distance between the user and the notebook screen is longer than is desirable for optimum viewing of the screen. It is an object of the present invention to provide a means of achieving the optimum view distance between a notebook screen and a user employing a separate keyboard.
DISCLOSURE OF INVENTION
According to one aspect of the present invention there is provided a notebook computer comprising a body portion with an integral keyboard and with a screen portion pivotally connected to the body portion, wherein the screen portion is positionable relative to the body portion such that the screen portion can be used in conjunction with a separate keyboard disposed at a distance from the screen portion corresponding to the optimum viewing distance for a user of the separate keyboard and closer to the screen portion than the depth of the body portion, wherein the screen portion is pivotable about a first axis between a first postition in which the notebook computer is closed and the integral keyboard is covered by the screen portion, a second position in which the screen portion has been rotated about the first axis through an angle of the order of 90° relative to the first position, and a third position in which the screen portion has been rotated about the first axis through an angle of the order of 270° relative to the first position.
According to another aspect of the present invention there is provided a notebook computer comprising a body portion with an integal keyboard and with a screen portion pivotally connected to the body portion, wherein the screen portion is pivotable about a first axis between a first position in which the notebook computer is closed and the integral keyboard is covered by the screen portion, a second position in which the screen portion has been rotated about the first axis through an angle of the order of 90° relative to the first position, and a third position in which the screen portion has been rotated about the first axis through an angle of the order of 270° relative to the first position.
The screen portion can be pivotally connected to a back edge of the body portion, and a docking connection disposed at a front edge of the body portion, the depth of the body portion corresponding to the distance between the front and back edges. In use of the external keyboard the screen portion is disposed in the third position. The body portion can be disposed upside down on a surface in such use, or, for example, means can be provided for reversing the image top-to-bottom on the screen, in order that the image is in the appropriate orientation.
BRIEF DESCRIPTION OF DRAWINGS
Embodiments of the invention will now be described with reference to the accompanying drawings, in which:
Figure 1 illustrates, schematically a conventional notebook computer being used in combination with a separate keyboard;
Figure 2 illustrates schematically a notebook computer according to one embodiment of the present invention being used in combination with a separate keyboard; Figure 3 illustrates highly schematically and not to scale a partial end view of a notebook computer according to the one embodiment of the present invention with the screen in the closed position; the normal (portable) open position (dashed lines) and the fully open position (dotted lines);
Figure 4 illustrates the notebook of Figure 3 with the screen in the fully open position and orientated for use (integral keyboard facing downwards) with an external keyboard, and
Figure 4A illustrates another possible arrangement of the notebook of Figure 3.
MODES FOR CARRYING OUT THE INVENTION
Referring firstly to Figure 1, which illustrates a conventional notebook computer 1 being used with a primary workstation keyboard 2, the screen 3 of the notebook computer 1 is being used as the primary workstation display. In this set-up, the body 4 of the notebook computer can prevent the keyboard 2 being positioned close enough to the screen so that the user 5 is at the optimum viewing distance from the screen. The screen 3 is hinged to the back edge of body 4 in such a manner that when the notebook computer is opened for use there is an angle between them that will be referred to as of the order of 90°, although in practice it can be somewhat greater and will be such as to provide an optimum view of the screen. In order to enable the keyboard 2 to be positioned closer to the screen 3 than previously possible, that is closer to the screen than the distance between the front and back edges of the body ie its depth, it is proposed to arrange that the relative positions of the screen 3 and the body 4 of the notebook computer be changeable. One possible means of achieving this is to provide a hinge arrangement between the screen 3 and the body 4 at the back edge thereof that enables the notebook computer to be opened to such an extent that there is an angle between them which will be referred to as of the order of 270°, although in practice it can be somewhat greater in order to provide an optimum view of the screen. Such an arrangement is illustrated in Figure 2, in which the notebook computer has been opened up to the order of 270° and the body has been positioned on a work top with the integral keyboard facing downwards. Figure 3 illustrates very schematically, in order to indicate the principle, a partial end view of a notebook computer having a screen able to pivot about an axis 4A and open to such an extent, and indicating the closed position of the screen 3 relative to the body 4 in a solid line, the normal of the order of 90° viewing position of the screen in a dashed line 3A, and the order of 270° viewing position of the screen in a dotted line 3B. To enable the screen to be viewed with the image the right way up in the order of 270° orientation the body 4 must be disposed with the integral keyboard 4B downwards, as indicated in Figure 4.
In the order of 270° orientation illustrated in Figure 3 the image on the screen is the wrong way up when the body is disposed with the integral keyboard uppermost. If the image could be reversed (top to bottom) this order of 270° orientation could also be employed by, for example, disposing the body 4 at a higher level than the keyboard 2, for example, on some form of shelf, and with the integral keyboard uppermost. In such a case the orientation would be somewhat less than 270° for optimum viewing. Such an arrangement might be preferable in certain circumstances, particularly in connection with CD Roms or floppy disks, the drives for which may not operate in an upside down configuration, as well as possibly being difficult to use when upside down. Instead of disposing the body on a shelf and angling the screen as appropriate, the opened out notebook computer could just be stood up as illustrated schematically in Figure 4A, in which the angle will be greater than 270° and the image will need reversing, top to bottom. Locking means could be provided to ensure that this angle is maintained.
In the arrangements illustrated in Figures 2, 3 and 4, a docking connection 6 can be disposed at the front of the body 4 in order to be accessible when the order of 270° orientation is employed (Figure 4), the docking connection being required when the screen is to be used as a primary workstation display. Connections 7 which are required when the notebook computer is to be used in the normal order of 90° orientation can be disposed at the back of the body as illustrated, these include parallel and serial ports. Locking means (not shown) are preferably provided in order to lock the screen into the desired orientation (90 or 270°).
The arrangements proposed by the invention thus permit the screen of a notebook computer to be used as a primary workstation display, saving the cost of purchasing a CRT monitor or other display for the workstation, whilst allowing an external keyboard to be positioned close enough to the screen for optimum viewing thereof by a keyboard user.
