Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a data input device using a virtual position using a pointing device that can increase the effective display area of a display screen.

[Prior art and its problems]

Conventionally, when inputting data such as numerical values using a pointing device such as a mouse, first a numeric keypad is displayed in an overlapping manner on a part of the CRT as shown in FIG. After moving the mouse cursor to , the numerical value was selected and input by a switch operation from the mouse, as shown in FIG. 5 (bl).

However, according to the conventional example described above, guidance such as a numeric keypad is displayed overlapping the currently displayed screen, which causes the problem that the originally displayed screen cannot be seen in that area. had.

Furthermore, if the display area for guidance is always left open in order to avoid the above-mentioned problem, there is a problem in that the effective display area becomes small.

[Purpose of the invention]

In order to eliminate the above-mentioned problems, the present invention provides a data input device using a virtual position using a pointing device that does not provide a guidance area and can prevent effective display from becoming invisible due to overlapping display. The purpose is to

[Key points of the invention]

The present invention further includes a CRT (11) that displays only the data designated by the address designation at a predetermined position on the screen;
data output means (8, 1) outputting the data by a switch operation from the pointing device (6);

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described in detail.

FIG. 1 is a block diagram of a data input device according to the present invention. X-Y movement data 14 from the mouse 6 is separated into X-coordinates and Y-coordinates by an X-Y coordinate conversion circuit 7, and then transferred to an address on the memory 1 via an X-coordinate latch 2 and a Y-coordinate latch 3, respectively. Specify. The XY designation data 18 at the address on the memory 1 based on the address designation is held in the XY designation data output latch 9, and then displayed on the CRT II via the CRT controller 10. Further, the switch data 15 from the mouse 6 controls the AND gate 12 via the switch control circuit 8, and selectively outputs the X-Y designated data 18 held in the X-Y designated data output latch 9 to the output terminal 13. Make more output. On the other hand, the initial human power X-Y coordinate data 16 from the initial input data setting circuit 5 specifies an address on the memory 1 via the X-Y coordinate conversion circuit 7, the X-coordinate latch 2, and the Y-coordinate latch 3. Initial input data 17 from the initial input data setting circuit 5 is written to the address via the initial input data latch 4.

In the data input device having the above configuration, the initial setting operation will first be explained. The initial input data to be written into the memory 1 can be set by the initial input data setting circuit 5. That is, by the initial human power X-Y coordinate data 16 given by the initial input data setting circuit 5,
- The address on the memo IJ1 is designated via the Y coordinate conversion circuit 7 and the X and Y coordinate latches 2 and 3, and the initial input data 17 can be written into the memory 1 via the initial input data latches 4. As the initial input data, various data patterns can be set as shown in FIG. 2(a), FIG. 3(al), and FIG. 4(al).

Next, mouse movement and data display operations will be explained.

X-Y movement data 14 from the mouse 6 is converted into an X coordinate and a Y coordinate via an X-Y coordinate conversion circuit 7, and each
and input to Y coordinate latches 2 and 3. Then, the pattern data on the memory 1 designated by using the data held in the latches 2 and 3 as an address is transferred to the X-Y designated data 18.
After being held in the X-Y designated data output latch 9 as
It is always displayed on the CRTll via the CRT controller 10. At this time, as the mouse moves, the X-Y instruction data 18 output from the memory 1 also changes, and the display data on the CRT 11 also changes. Assume now that the data pattern shown in FIG. 2(a) is stored in the memory 1, for example.

When data 1 is initially displayed on the upper left of the CRTII screen, if the mouse 6 is moved to the right, the address specification on the memory 1 will be moved to the right via the X coordinate latch 2, as shown in Figure 2. (As shown in bl, the data display is 2-
Changes to 3. Conversely, if the mouse 6 is moved to the left, the data display similarly changes as shown in FIG. 2(e). Figure 3 (al) is an example in which the data pattern of the numeric keypad is stored in the memory 1. ) as shown in FIG. (a) is an example in which the data pattern of the symbol is stored in the memory 1. When data A+ is displayed and when the mouse 6 is moved diagonally to the lower right, the fourth
As shown in the figure (bl), the data display changes as A1→B2=Cz.

As described above, the mouse 6 can move around arbitrarily in the virtual space where data patterns exist, that is, in the address space of the memory l, and transfers only data at a specified arbitrary virtual position, that is, an address, onto the CRTII. can be displayed. This allows the data display area on the CRTII to be extremely small, and data can be displayed freely by moving the mouse 6 in the virtual space (address space) of memory 1, which does not appear on the screen. .

Next, the output operation of the display data will be explained.

CR the desired data as explained in Figures 2 to 4.
If the display can be displayed on the TII, press the switch button 61 of the mouse 6 at that point to display the switch data 1.
5 is output, and the AND gate 12 is turned on via the switch control circuit 8. As a result, the same X-Y designated data 18 as the display data on the CRTII held in the X-Y designated data output latch 9 is outputted from the output terminal 13 via the AND gate 12. This allows desired data to be captured.

In the above embodiment, the data display area on the CRTII may be provided at any position as long as the minimum area (at least one character) that does not interfere with other display screens.

〔Effect of the invention〕

According to the present invention, since there is almost no guidance area for displaying data patterns, a large effective display area can be obtained. This prevents the guidance from being displayed in an overlapping manner (this prevents the effective display from becoming even temporarily invisible).
