Abstract

The projector screen (1) comprises separately assembled optics (18), a revolving projection head (7) with an arm (5), a power supply casing (3) screwed together with a front panel (6) which comprises an infrared receiver (3), and an external electronic circuit (15) which is connected with the LCD (8) of the optics through a cable (13). The power supply transformer (16), the projection head, and the electronics are assembled separately of each other. The electronics are preferably assembled compact in the computer and form an I/O card (19).

Description

Es sind bereits LCD-Projektoren bekannt, welche, getrennt von der Projektionsfläche, sowohl eine Rück- als auch eine Frontprojektion ermöglichen. Dabei ist der Abstand zu der Projektions- Fläche meisten sehr groß. Bei solchen Projektoren sind Netzteil, Elektronik, LCD-Schirm und der Optik fest integriert so daß sich nur in einigen Fällen ein sehr kleiner Projektor realisieren läßt der bei Bedarf immer von Neuem eingestellt werden muß. Bei bekannten Ausführungsformen dieser Art ist die Mobilität und Flexibilität jedoch unzureichend.LCD projectors are already known, which, both separately from the projection surface enable a rear as well as a front projection. The distance to the projection Most of the area is very large. Such projectors include power supply, electronics, LCD screen and the optics firmly integrated so that a very small projector can only be realized in some cases which must always be set again if necessary. In known embodiments however, mobility and flexibility of this kind are insufficient.

Um diesen Nachteil zu beseitigen, sind erfindungsgemäß bei einem Projektor in der oben beschriebenen Art mindestens die großen Bausteine voneinander getrennt montiert und mit der Projektionsfläche als Desktop-Projektor kombiniert. Durch die Trennung kann der Projektionskopf auch gedreht werden und somit eine größere Projektionsfläche, ohne Aufwand, verwendet werden kann. Auf diese Weise ist es möglich eine vielseitige ineinander greifende Darstellung, unproblematisch flexibel zu gestalten.In order to eliminate this disadvantage, according to the invention, a projector in the type described above mounted at least the large blocks separately and combined with the projection surface as a desktop projector. By separation the projection head can also be rotated and thus a larger projection area, can be used without effort. In this way it is possible to have a versatile interlocking gripping presentation, flexible to design without problems.

Da bei Verwendung üblicher Projektoren viele Bausteine der Elektronik auch in I/O Karten enthalten sind, ein Beispiel ist die Videokarte, wird die Elektronik nach einem weiteren Merkmal der Erfindung bewußt auf das Motherboard verlagert um hier doppelt vorhandene Bausteine zu entfernen um zusätzlich Platz zu gewinnen.Since when using conventional projectors, many components of the electronics are also in I / O cards are included, one example is the video card, the electronics will look for another Feature of the invention deliberately shifted to the motherboard to duplicate here Remove blocks to gain additional space.

Zur Vereinfachung der Herstellung und zur Erleichterung der Montage sind die Bausteine zweckmäßig als Bausatz zu kombinieren, wobei der Desktopprojektor auch als Monitor und TV-ersatz benutzt werden kann.To simplify manufacture and to facilitate assembly, the Appropriately combine building blocks as a kit, the desktop projector also as Monitor and TV replacement can be used.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Es stellen dar:The drawing shows an embodiment of the invention. They represent:

Fig. 1 Den Schnitt durch den Projektor, Fig. 1 is a section through the projector,

Fig. 2 Die Frontansicht mit ausgeschnittener Projektionsfläche, Fig. 2 shows the front view with cut-out projection,

Fig. 3 Den Horizontalschnitt mit Anzeige der Drehbewegung, Fig. 3 shows the horizontal section with indication of the rotational movement,

Fig. 4 Bausteinanordnung. Fig. 4 block arrangement.

Auf der Drehscheibe 4 ist mittels einer Achse 11 das Netzteil 16 und das Frontpaneel 6 drehbar gelagert. Zwischen den Lautsprecherboxen 2 ,auf dem Frontpaneel 6 ist die Projektionsfläche 1 befestigt. Fest montiert an das Netzteilgehäuse mit Infrarotempfang 3 ist der Projektionsarm 5 der den Projektionskopf 7 trägt. Die Strom- und Elektronik Verbindungskabel werden durch den Projektionsarm 5 in das Netzteilgehäuse 3 geleitet und weiter an das Netz bzw. I/O Anschluß der Karte 19.On the turntable 4 , the power supply 16 and the front panel 6 are rotatably mounted by means of an axis 11 . The projection surface 1 is fastened on the front panel 6 between the loudspeaker boxes 2 . The projection arm 5, which carries the projection head 7, is fixedly mounted on the power supply housing with infrared reception 3 . The power and electronics connection cables are passed through the projection arm 5 into the power supply unit housing 3 and on to the network or I / O connection of the card 19 .

Fig. 2 Zeigt die Ansicht mit den seitlich gelagerten Lautsprecherboxen 2 der manuellen Tonregelung 9 und des Infrarotempfangs 3. Fig. 2 shows the view with the laterally mounted loudspeakers 2 the manual tone control 9 and the infrared reception. 3

Fig. 3 Zeigt die Optik des Projektionskopfes. Fig. 3 shows the optics of the projection head.

Wie Fig. 4 erkennen läßt ist die bausteinförmige, modular gegliederte, Einheit des Desktopprojektors funktionsgerecht verteilt.As can be seen in FIG. 4, the block-shaped, modularly structured unit of the desktop projector is functionally distributed.
