›BACKGROUND OF THE INVENTION

I. Field of the Invention

This invention relates generally to a projector and, more specifically, to an integrated projector that can work independently without extra wiring for users to read the data in the memory card, to watch TV and to watch DVD.

II. Description of the Prior Art

Heretofore, it is known that people ask for more and more high entertainment quality, many families have home theater equipment; the early day projectors were very bulky in size and very high in cost to be accepted by regular families. By the improvement of manufacturers, now the projectors have tiny internal electronic circuit and smaller in overall size, the price is much lower for general public to accept.

As in Taiwan Utility Model patent publication no. 5200411, an off-axis LCD projector compromises of a light source, an X-type dichroic filter device, a color combination device, three polarizers and three LCD, three polarized analyzers corresponding to three polarizers. The light source is separated into red, green and blue beams by dichroic filter device, each light beam injects to the corresponding LCD of the direction defined by each polarizer; each LCD adjusts and reflects the injected light beam to the corresponding polarized analyzers. The major character of this invention: the directions of the polarizers are vertical to the injected light beam, the directions of the polarized analyzers are vertical the adjusted light beam.

Even the most advanced design, the current projectors can only output image, as shown in FIG. 1 , the projector must be connected to a computer or a TV tuner, if users want to watch TV, the extra wiring is needed to connect projector, TV tuner and other audio devices; if users want to output computer images, extra wiring also have to be connected between projector and computer. Users cannot see the pictures of digital cameras from projector; the picture images have to be downloaded into a computer then output from the projector. The audio output needs more wiring, the installation might not be a problem for general people, and however it might be too complex for senior or younger people and those inexperienced.

›SUMMARY OF THE INVENTION

It is therefore a primary object of the invention to provide an integrated projector in which users can read the data in the memory card, watch TV and watch DVD with a single projector without extra wiring.

In order to achieve the objective set forth, a integrated projector in accordance with the present invention comprises a body with a projector circuit internally and a projection lens externally, a card reader installed on the body to read the data inside the memory card, a video interface installed on the body to receive video signals, and a video player that is a DVD player built-in inside the body.

›BRIEF DESCRIPTION OF THE DRAWINGS

The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:

FIG. 1 is an application view of the prior art;

FIG. 2 is a block diagram of the present invention;

FIG. 3 is a perspective view of the present invention;

FIG. 4 is a an application view of the present invention;

FIG. 5 is an assembly view of another application in accordance with the present invention;

FIG. 6 is a perspective view of another application in accordance with the present invention.

›DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 2 to FIG. 6 , the present invention is composed of a body 1 , a card reader 2 , a video interface 3 and a video player 4 . The functions of each component are described below:

The body 1 has a projector circuit 11 internally and a projection lens 12 externally.

The card reader 2 is installed on the body 1 to read the data inside the memory card 21 .

The video interface 3 is installed on the body 1 to receive video signals.

The video player 4 is a DVD player built-in inside the body 1 .

The body 1 combines all the required equipment internally and directly that results in smaller physical size; with the shared circuitries that reduces the individual shells needed originally, the cost is also lower, the operation is also simpler without external wires, the operation is friendly to all ages of people. Users can read the data in the memory card 21 , watch TV and play DVD with the single projector.

Referring to FIG. 2 to FIG. 4 , for the convenience of users, the body 1 installs a wireless audio output circuit 13 , such as an audio frequency module or a Bluetooth wireless transmission module (not shown in FIG); the wireless active speaker 5 are installed externally for much more flexibility in space panning; the speakers can be anywhere without the limitation by wiring. A wireless receiving circuit 14 is inside the body 1 to receive the commands from a remote controller 6 , users can control the body 1 , the card reader 2 , the video interface 3 , the video player 4 and the wireless active speaker 5 wirelessly, such scheme improves the poor planning of the prior art with too many remote controllerlers.

Referring to FIG. 2 , FIG. 5 and FIG. 6 , the video player 4 of the present invention can also be separated from the body 1 , the external DVD player is connected to the body 1 with a connector and fastened to the body 1 with a fastener 8 ; the independent video player 4 can connects to other display apparatus by users for more selections to buy the DVD player separately.

While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
