Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a graphic character display device used in word processors, personal computers, etc., which displays graphic characters and heart characters.

Conventionally, this type of device is shown in FIG. 1, which has a ROM as a storage section, 3 a chart character display section that displays chart characters according to a chart character pattern, and 4 a chart character code receiving section 1.
Chart character storage ROM according to the chart character code received by
This is a control section that reads out the graphic character pattern from the graphic character display section 2 and sends it to the graphic character display section 3, as well as controlling the position of the cursor displayed on the display section 3.

Figure 3 (al) (b) shows the display screen for character display and chart display, respectively. In the figure, 9 is a character, 7 is a ruled line, and 6 is a cursor. Even when displayed, the shape is the same.

Next, the operation will be explained. The chart character code receiving section 1 receives chart character codes and control codes such as JIS6226 from the outside, and sends them to the control section 4.

Now, when the receiving section 1 receives a chart character code, the control section 4 reads out the chart character pattern stored in association with the chart character code from the chart character storage ROM 2 and sends it to the chart character display section 3.

Further, if the received control code is a display position control code, the control section 4 changes the chart character display position to the chart character display section 3.
Send to. On the other hand, if the received control code is a cursor control code, the control section 4 sends a fixed cursor pattern to the indicated position on the chart/character display section 30.

Since the conventional figure/table character display position is configured and arranged as described above, as shown in Fig. 3, while moving the cursor 6, a linear figure such as the ruled line 7 is displayed at the cursor position. In this case, it was extremely difficult to identify the ruled line 7 at the cursor position, and this graphic character display device was used to assist in checking the computer input of the diagram.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and outputs a cursor pattern with a different shape depending on whether the received code is a diagram code or a character code, or depending on the content of the control code. It is an object of the present invention to provide a chart/charter display device in which the shape of a cursor changes depending on whether characters are displayed or charts are displayed by adding a circuit to do so.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 2, 1 is a chart character code receiving unit that receives chart character codes and control codes, and 2 is a chart character display unit that displays chart characters at the cursor position according to each of the chart character codes that can be received by this receiving unit 1. , 4 is a control unit which reads the chart character pattern from the chart character storage ROM 2 and sends it to the chart character display unit 3 according to the chart character code received by the receiving unit 1, and also controls the position of the cursor.
・, (This is the control section that controls the control section. Also, 5 is the control section 4
A cursor shape generation circuit connected to, for example, R
The control section 4 outputs different cursor patterns depending on the control code received from the chart character code receiving section l.

Figures 4(a) and 4(b) respectively show the display screens of characters and charts in the device of this embodiment. , 8 is a cursor. In this case, the cursor 6 for character display and the cursor 8 for graphic display have different shapes.

Next, the operation will be explained. The chart character code receiving unit 1 receives chart character codes and control codes such as JIS6226 from the outside, and sends them to the control unit 4.

If the code received by the control unit 4 via the reception unit l is a chart character code, the control unit 4 transfers the chart character pattern stored in association with the chart character code to the chart character storage R.
It is read from the OM2 and sent to the chart character display section 3. The graphic character display section 3 displays the graphic characters BUTTER & ENGINE sent to the position of the cursor. After the display, the cursor is moved to the position indicated by the control unit 4.

On the other hand, the cursor shape generation circuit 5 outputs a cursor pattern for displaying characters or a cursor pattern for displaying charts according to the content of the control code received by the control unit 4, and this cursor pattern is sent via the control unit 4. Then, it is sent to the chart/charter display section 3.

In this device, as shown in FIG. 4, the cursor 6 for character display and the cursor 8 for graphic display have different shapes, so that the point indicated by the cursor 8 on the ruled line 7 is clear.

In the above embodiment, the cursor pattern is changed according to the control code, but in the present invention, the control unit 4 determines whether the received code is a character code or a diagram code, and the cursor shape is changed accordingly. It may be something that does.

Further, in the above embodiment, the cursor shape generation circuit is provided outside the control section 4, but the control section 4 itself may be able to generate different cursor patterns through software processing.

Further, in the above embodiment, a graphic character display device has been described, but a graphic character display unit of a personal computer or a word processor may be used, and the same effects as in the above embodiment can be obtained.

As described above, according to the present invention, in the diagram/chart character display device, a circuit is added to the control unit for outputting cursor patterns of different shapes for character display and diagram display. , etc., the cursor pointing point can be easily identified.
