Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a display device that displays characters and figures on a cathode ray tube, display, or the like.

(Technical Background of the Invention) Rectangular display screens have conventionally been used in display devices such as cathode ray tubes and displays used in various computer terminal devices. When displaying characters on such a display device, the number of characters that can be displayed in the horizontal and vertical directions naturally becomes important.

For example, the screen is set horizontally to match the image of a rectangular slip, so that the number of characters that can be displayed in the horizontal direction increases.

(Problems with Yellow Steel Technology) However, in general sentence processing, the number of lines in the vertical direction may be greater than the number of characters in the horizontal direction. For such uses, there are disadvantages in that only a small number of characters can be used per line, the blank space on one side is wasted, and the number of lines that can be displayed is reduced.

(Object of the invention) The present invention has been made to solve the above-mentioned drawbacks.
It is an object of the present invention to provide a display device in which 11 rectangular display surfaces are configured to be rotatable by 90 degrees parallel to the screen, and are provided with a character control function to display characters in accordance with the screen.

(Summary of the Invention) The present invention includes a display section having a screen rotation mechanism, a screen angle detection section that detects the rotation angle of the screen, a screen memory that stores a screen image, and a character button that sends a character button to a predetermined address of the screen memory. It is composed of a screen memory write control section for writing, and a character stamp memory for storing character stamps corresponding to the character code, and the screen memory write control section controls the character stamps according to the signal from the screen angle detection section. It is characterized by having a function of selecting a write address to the screen memory.

According to the present invention, with the above configuration and C, it is possible to effectively utilize the screen for both portrait and landscape documents.

(Embodiment of the Invention) FIG. 1 is a perspective view showing an embodiment of the display image of the present invention in a horizontally oriented state, and FIG. 2 is a perspective view showing a vertically oriented state. In the display device shown in the figure, a display section 1, an operation section 2, and a holding device 3 provided with a rotation mechanism for the display section 1 are integrally constructed.

The display unit 1, which has one rectangular surface, is 90'' parallel to the screen.
It is rotatable and can be changed from the horizontally long state shown in FIG. 1 to the vertically long state shown in the second river.

FIG. 3 is a block diagram showing a state in which the display device 4 and the computer 5 of the present invention are connected.

This display device 4 displays 1IiiiIi from the electronic computer 5.
A screen output control section 6 receives character code information of a control code for display and performs control for screen output, and receives the character code information from this screen output control section 6 and converts it into an address of the character button memory. Character slam address converter 8
, the character-bang memory 7 stores the dot-bang image of the character corresponding to the character code, and the screen memory receives the character display position information from the screen output control section 6 and the character dot-bang information from the character bang memory 7. Screen memory write control unit 9 that writes a character dot button in the corresponding position
is provided. The screen memory write control unit 9 then
A screen memo 10 stores dot information corresponding to one-to-one dots on the screen, a display control section 11 reads out display data in the screen memory 10, and a display section 1 performs screen display.
are connected in order.

On the other hand, the display device of the present invention is provided with a screen angle detection section 12 that detects whether the screen is vertically long as shown in FIG. 2 or horizontally long as shown in FIG. The screen angle detection section 12 is connected to the angle information holding section 13. The angle information holding section 13 holds -face angle thinning information and sends a screen angle state signal to the computer 5, and also supplies the angle state signal to the character button 8 and the screen memory writing control section 9.

Furthermore, this display device includes an input operation section 2 such as a keyboard, and information inputted from this input operation section 2 is transmitted to an electronic computer 5.
In addition, an input control section 14 is provided to send control information and character information to the screen output control section 6 in order to display characters, etc. input from the input operation section 2 on the display section 1 without going through the computer 5. It is being

The display device of the present invention having the above configuration is used as follows.

First, when using the display device, when the operator rotates the display unit 1 to set the screen in landscape or portrait orientation, the angle state of the screen is detected by the angle information holding unit through the screen angle detection unit 12, which includes a limit switch, etc. 13. At this time, the angle information is stored as, for example, horizontal=0 and *-i. When the operator finishes setting one page, he operates the input operation section 2 to send a signal of completion of setting to the computer 5 via the input control section 14.

The computer 5 can check whether the display section is set correctly by reading the angle information from the angle information holding section 13 as a status signal. As a result, the computer 5 sets nine logical addresses of character display positions on the screen corresponding to the number of characters that can be displayed on the screen, that is, the number of characters in the horizontal direction and the number of characters in the vertical direction. For example, as shown in Figures 4 and 5, the address of the character position that can be displayed on the screen is X-1 to 100 in the horizontal case, Y-1 to Y-1
50, and in the case of vertical, it is set in the range of x-1 to 50 and Y-1 to 100.

The electronic calculator 115 outputs a character code for displaying characters on the display device 4 and a control code regarding the display position of the characters. In this case, control of display position 1 is given by the above-mentioned X, Y logical addresses. Upon receiving this information, the screen output control section 6 sends the character code to the character stamp address conversion section 8 and the XY address to the screen memory included control section 9. The character stamp address conversion section 8 converts the character code into an address on the character stamp memory 7 where the character stamp corresponding to this character code is stored. In the character button memory 7, as shown in FIG. 6 for the same character, two types of button are registered in advance, each of which has been vertically and horizontally converted, corresponding to the horizontal or vertical direction of the screen. Therefore, as shown in FIG.
Or one of the characters on the vertical button 23, 1i
iii. The memory write control section 9 selects and determines the address of the - side memory for vertical or horizontal use based on the XY address from the screen output control section 6 and the horizontal line status signal from the angle information holding section 13, and writes the character button. The character dot button read out from the memory 7 is written into the screen memory 10.

Figure 7 shows this situation.

For example, in the horizontal direction of the cathode ray tube that constitutes the display section 1,
Assuming that 50 characters can be displayed in the vertical direction, if each character is composed of 24×24 dots, the screen will be formed of dots of 0 to 2399 in the horizontal direction and 0 to 1199 in the vertical direction, as shown in the figure.

Here, (X1Y) is the logical address of the character, and (x,
If y) is the screen memory start address when the character is displayed on one side, then when the screen is placed horizontally and vertically, the relationship between the numbers X, V, and X1Y is expressed as shown below.

Horizontal: X-(X-1)X24 V = (Y-1") X24 Vertical: x-(Y-1) When trying to form a character display device at the logical address Y-20, based on this formula, in the horizontal direction x = 216, v = 456, and in the vertical direction x = 456
, y =960, and are displayed as shown in FIG. This address conversion is performed by the screen memory included control section.

In the embodiment L below, the character button memory is made to have both a vertical character button and a horizontal character button, but only one type of character button is stored in the character button memory, and this character button is After reading out the character, the character may be placed in the normal position by rotation processing or the like.

Furthermore, the character display position on the screen memory in the above embodiment does not necessarily have to be considered as a square character dot button area. The character dot button may be rectangular, or a space may be provided around the character dot button for character spacing or line spacing. In other words, the problem can be solved by providing the one-sided memory write control section 9 with an address conversion function suitable for the display method on the negative side.

Further, although the electronic computer is assumed to be external to the display device, it may be built into the display device and have an integral structure, such as a stand-alone word processor.

(Effects of the Invention) As explained above, in the display device of the present invention, by rotating the screen, the degree of freedom in the display area of the screen is improved, and easy-to-see display is possible. In addition, display addresses can be managed logically and carefully within the display device, so there is no need for complicated management on the computer side.

Furthermore, when viewing the screen of a display device in a word processor, etc. in relation to the paper, rotating the screen can be seen as the same image as determining whether to use the paper vertically or horizontally. , it can be operated with the same feeling as doing paper work, which has the effect of reducing psychological resistance for the operator.

Furthermore, when used for typesetting etc. for Japanese printing,
By rotating the screen for both vertical and horizontal writing. You can choose to increase the number of characters per line or increase the number of lines, which has the effect of making typesetting work easier.
