In the system to which the present invention is applied, as shown in FIG. 3, the arithmetic processing unit (arithmetic processing means) 11 consisting of MPUI to RAM 3 and the external storage 9 consisting of FDD are replaced according to the needs of the application. The main body housing 12 houses an FD (:/HDC 8, a keyboard interface 6, an FDD/HDD 9, a power supply (not shown), etc.).

The gist of the present invention is that the display section 10 shown in FIG.
The device can be attached and detached, and the display content as shown in FIG. 4 can be displayed even when it is removed from the main body casing as shown in FIG.

Therefore, a display section 10 as shown in FIG. 1 is configured. 1st
In the figure, 100 is an MPU address/data bus, to which the MPUI shown in FIG. 2 is connected. In an information processing device such as a personal computer, the content processed by the arithmetic processing unit 11 is displayed on the display device 5.
The MPUI uses the video RAM (display memory) through the drawing processing LSI 43 via the arithmetic processing unit interface 41.
44, or write the drawing data 600 to the MP
According to the UI command, draw 1, S I 43, circle, straight line,
Generate a rectangle and write it to video RAM. In order to display this, the read address 300 is sent to the display control LSI (display control means) 42 or the video RAM 44, and the display data 400. are sequentially read out and converted into analog data 50 by the DA converter 45.
0 and supplies it to the display device 5, and also sends a synchronization signal 200 to the display device 5.

When the display section 10 is removed from the main body case, a contact in the switch (SW) 47 is turned on, and the power source is automatically switched from the main body case side to the battery 48 inside the display section 10. As a means for this switching, a well-known method can be used. The battery may be rechargeable or non-rechargeable, and from the viewpoint of ease of use, it may be rechargeable, and it is preferable that charging be performed while it is connected to the main body housing.

As a result, the power supply for the display section is secured and the old MP is connected or disconnected. Therefore, no commands are received from the MPU 1 from now on, and the display unit 1O shifts to the video RAM readout mode operation only under the display control 1.5I42 and continues to display.

Note that the arithmetic processing interface 41 of the display unit 1O is

Fig. 6 does not show a facsimile machine to which the present invention is applied; a display unit with an integrated display device and display control circuit is inserted into the facsimile machine, and data is written by an information processing device such as a burner computer. An example of sending displayed data by facsimile is shown below.

First, the operation of the facsimile will be explained according to FIG.

In facsimile, a document to be transmitted is illuminated with illumination light from a light source (not shown), and the reflected light is converted into an analog electric signal 70 by a photoelectric converter 60 and input to the digitalization and buffer link circuit 20. At this time, timing controller 1
~Roller 50 sends control signals ]1.0[1 and ]200 to photoelectric converter 60 and digitizing buffer link circuit 20.

The facsimile transfers the buffer-linked digital data 80 [ ] from the circuit 20 to the information compression circuit 30 .

This circuit compresses information using the so-called run-length method, which calculates the continuous length of each piece of data according to black and white data on a form. Thereafter, the transmitting circuit 40 outputs an output of 1000 to the line.

The same operation is possible even without the buffer of the circuit 20, or there is no need to speed up the information compression process if the buffer of the circuit 20 is provided.

If the above is the operation of the facsimile to which the present invention is applied, when the display section 10 is removed from the main body casing 12 and inserted into the facsimile, the display section 10 will display the following as described above.
Continue to supply display data. In this case, Figure 1 and 6U
As shown in A, the timing controller on the facsimile side
- Connect the output 1100 of the roller 50 to the external synchronization input terminal of the display control LSI 42 of the display unit 10, and send the output display data 400 of the video RAM 44 to the information compression circuit 30 of the facsimile. This makes it possible to read out data on the display unit 10 in synchronization with facsimile timing.

Note that a facsimile machine to which the present invention is applied requires a connection mechanism with a display section.

According to the above two embodiments, (1) the already processed video RAM circle data can be continued to be displayed even when the display section is removed from the main body housing, and the user can freely view it wherever he/she wants to view it; You can check the displayed content by holding only the display panel while holding the display.

(2) According to another embodiment, by inserting the display unit into a facsimile machine, data can be transmitted as is.

[Effects of the Invention] According to the present invention, by integrating a display device and a display control circuit, providing a connection mechanism with the main body housing, and providing battery backup, the main processing content can be displayed even when removed from the main body housing. It is possible. However, when you do not need arithmetic processing or input processing and only want to view displayed data, you can remove only the display section and view it without requiring the entire personal computer, which greatly increases work efficiency as well as spatial freedom. It seems to have the effect of improving the width.

Also, the contents of the display can be sent by inserting the removed display into a facsimile machine. In this way, it is now possible to make the information you want to send visible, whereas in the past you could only see it with your eyes.
It has the effect of improving things.
