Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a display device used in a terminal device or the like, and particularly to a display device suitable for vertical writing display.

[Background of the invention]

In the display method of conventional display devices, as described in Japanese Patent Publication No. 58-31593, two half-width characters or characters in vertical writing display are arranged horizontally in the full-width character area in the same way as in horizontal writing display. I'm going to do it.

The cursor is also displayed as a half-pitch or one-pitch cursor on the right side of the displayed characters.

However, in actual use, the conventional example described above has problems in that continuous display of half-width characters << is not possible, and the cursor position is too far apart to make it difficult to understand.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned problems of the prior art, and the present invention is a display device that is capable of continuously displaying half-width characters when displaying vertical writing, and that can cunningly display a cursor at the display position of half-width characters. is intended to provide.

[Summary of the invention]

The display device of the present invention can display horizontal writing on a cathode ray tube or the like.
It is a display device that can display vertical writing, and includes a switching means for switching between horizontal writing display and vertical writing display, and when the switching means is set to switch to vertical writing, 1 When the displayed characters are full-width characters, double-width characters are displayed. A cursor control means that moves the cursor under the minute, and when the display character is a half-width character, a cursor control means that moves the cursor under the half-width character, and when the switching means is set to vertical writing, when the horizontal writing display is set. A sentence that rotates the character display signal by 90 degrees - T, rotation that outputs the display signal? ! LJ? It is characterized by being equipped with an MJ means.

[%Example of invention]

Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the accompanying drawings.

Figures 2 to 5 are diagrams showing specific examples of horizontal writing display using the display device of the present invention. In the figure, A
is a character block that displays one full-width character. Figure 2 shows the 1st power ``ゝarithm'' displayed on a cathode ray tube. Next, in order to input double-byte characters, a cursor C1 is displayed by selection from the keyboard or the like. Here 1
When you enter the expression ", the display as shown in Figure 3 is displayed, and cursor C2 is displayed. If you want to input half-width characters, select from the keyboard etc. to move half of the normal cursor as shown in Figure 4. The cursor C3 with the length of is displayed. Then, by inputting 'X'', the fifth
As shown in the figure, the cursor C4 is displayed at the same time that 'X'' is displayed. Figures 6 to 10 are diagrams showing specific examples of vertical text display using the display device of the present invention. .Figure 6 shows a state in which the first power "1 calculation" is displayed vertically in the character block.Then, in the next character block, a cursor Cs indicating that a full-width character is to be input is displayed. If you input the formula 1 here, the screen will be displayed as shown in FIG. 7, and the cursor C6 will be displayed.

If you want to input half-width characters, instead of selecting them from the keyboard, move the cursor C7 as shown in Figure 8.
The full-width character compartment is displayed in the upper half of the person's nine positions at normal length. When hX" is input, the half-width character 1X" is displayed rotated by 90 degrees, and a cursor C8 is displayed, as shown in Figure 9. In FIG. 10, the half-width character 1+“ is shown.

%Y#, %2I1. %7. The display of the result of inputting If is shown.

FIG. 1 is a block diagram showing an embodiment of the present invention that performs the above display. In the figure, 1 is a horizontal/vertical writing switching circuit, 2 is a rotation control circuit, 3 is a half-width character generation circuit, 4 is a cursor control circuit, 5 is a display character code buffer, 6 is a full-width character generation circuit, and 7 is a display 8 is an address counter, 8 is a cursor address register, 9 is a coincidence detection circuit, 10 is a gate circuit, and 11 is a gate circuit.

Explain the operation in depth. Specify vertical or horizontal writing, double-byte characters, etc. by switching signals from a keyboard (not shown), etc.
A designation for input selection of half-width characters is input to the horizontal writing/vertical writing switching circuit 1. Further, a full-width/half-width selection signal is input to the cursor control circuit 4. The output of the horizontal writing/vertical writing switching circuit 1 is input to the rotation control circuit 2, and when vertical writing is specified, the output of the half-width character generation circuit 3 is converted into a character pattern in which the character display signal LS is rotated by 90 degrees compared to when horizontal writing is specified. control the data.

On the other hand, the other output of the horizontal writing/vertical writing switching circuit 1 is input to the cursor control circuit 4.
A cursor address signal CA and a cursor length signal CL are output based on the output of the horizontal writing/vertical writing switching port @1 and the full-width/half-width selection signal. That is, during horizontal writing, a cursor length signal CL indicating 1 pitch/half pitch is output depending on full-width/half-width, and at the same time a cursor address word C is output.

:l Also, when writing vertically, the 1-pitch cursor length signal C
Cursor address signal C that is output at the same time as L.
A person is controlled so that the movement of the cursor moves between full-width character sections or half-width character sections. The output cursor address signal CA is set in the cursor address register 8, and the cursor length signal CL is input to the gate circuit 10. The cursor address signal C output from the cursor address register 8 and the count value output from the display address counter 7 are input to the coincidence detection circuit 9, and when the coincidence detection circuit 9 detects a coincidence between the two, the gate circuit 10 A cursor display signal CD is output through the cursor display signal CD.

The output of the display address carantuff controls the display character code buffer 5, refreshes the display character code buffer 5, and outputs the display character code C8. From the output of this display character code C8, the full-width character generation circuit 6 or the half-width character generation circuit 3 is accessed, and the character display signal L
8 is output. The cursor display signal CD and character display signal LS are supplied to a cathode ray tube circuit (not shown) through a gate circuit 11 as a video note vS.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the following effects can be obtained.

(1) *Cursor control circuit that moves the cursor at a full-width character pitch when displaying full-width characters, and moves the cursor at half the pitch of the full-width character pitch when displaying half-width characters. Since we have set up
The thickness of characters to be input can be easily classified by KR, and the input position can also be easily identified.

(2) When displaying half-width characters during vertical writing, one rotation control circuit that rotates the character display signal L8 by 901Jj is provided, so that half-width characters can be displayed continuously.

(3) The size of the characters to be input can be easily separated by Km, and
Since input positions can be easily separated by Kjl, operability can be greatly improved.
