Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an automatic projection device that automatically performs projection display.

[Prior Art] Conventionally, a CRT device is generally used as a display device connected to a computer, but it often has the disadvantage that it is difficult to display a large-sized display. On the other hand, there were overhead glodiectors and slide projectors as large display devices.
In either case, the display content was limited to fixed items prepared in advance as slides, etc., and could not be easily changed.

[Object and structure of the invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an automatic projection device that can easily change display contents and can automatically display large-sized displays. Niruru.

In order to achieve such an object, the present invention includes a transparent display, controls this display based on display data from a data processing section of a computer, and enlarges the display using a projection section. There is something that can be projected and displayed.

Hereinafter, the present invention will be explained in detail using Examples.

〔Example〕

The figure is a block diagram showing the configuration of an embodiment of the present invention.

In the figure, a data input section 100 includes a keyboard 110 equipped with a plurality of operators such as various keys for creating manuscripts consisting of sentences, diagrams, etc. and various switches for performing display operations such as display switching, and Let's start with the keyboard interface 120 for connecting to the data processing section 200. The data processing unit 200 is a CPU
etc. processor unit 210 and fixed memory 220
It also includes a variable memory 230, which processes data such as characters and figures input from the keyboard 110 according to the editing data, creates a display manuscript, and also processes various data and the created manuscript according to the input from the keyboard 110. It writes to the storage unit 300 and reads from the storage unit 300. It also controls the display unit 4009 and display control unit 410 to perform display according to the input from the operation keys, and also reads data from other devices, such as a word processor, etc. via the external communication interface 500. After sending the data.

The storage unit 300 stores documents created by the data processing unit 200, data stored in the data processing unit 200 from the keyboard 110, or other devices. It consists of a magnetic disk 31° for storing data necessary for creating a manuscript input via a disk interface 320.

There are two types of disks: a hard disk and a floppy disk. In the case of a floppy disk, data and manuscripts created on other devices can be imported into this device via the floppy disk. Other storage media can also be used in place of the disk, such as a magnetic bubble memory device.

A display section 400h, and a data processing section 200 as described above.
Display control unit 41 controlled by display data from
0, and the display control section 410 drives and controls the display 42G to perform display according to the display data. The display 420 consists of a dot matrix liquid crystal display well known in liquid crystal televisions. There are two types of liquid crystal display: reflective display and transmissive display.
In Komu, a transparent type is used. The display section 400 further includes a light source 431 and an optical system 432 in the projection section 430, and displays the display on the display 420 on the screen 4 through a reflection plate 433.
It has a function similar to that of an over-the-radar projector that enlarges and projects images onto 34.

In the above configuration, when used as a display device connected to a computer like a conventional CRT, data from the computer can be displayed on the screen by connecting the display section 400 to the data processing section 20Q consisting of the computer. Can be displayed in large size.

On the other hand, when used as an overherad projector, the originals stored in the storage unit 300 can be sequentially displayed on the screen 434 by simply operating a switch on the keyboard 110, whereas in the past it was necessary to operate the originals using the projector. The screen can be displayed on the screen, and display operations can be performed automatically.

Further, by processing the data in the data processing unit 200, editing such as combining a part of the manuscript with another manuscript can be easily performed. It is also possible to overlap another handwritten manuscript using the transmissive display 420.

Furthermore, if you connect to external devices such as a word processor or other office computer via the external communication interface 500, data and manuscripts created using those external data can be processed. Data input through the input section 100 can be used in the same way as a manuscript created through the data processing section 200.

〔Effect of the invention〕

As explained above, according to the present invention, a display connected to a computer is provided by driving and controlling a transmissive display by a data processing unit and including a projection unit that projects and enlarges the display. As a device, it is possible to perform large-sized displays, display operations can be performed easily and automatically, and display contents can be freely changed, making it possible to use the device as an over-the-top projector.
