2. Description of the Related Art In a conventional tablet-type figure-input-type touch panel, in order to decide from which position on the CRT screen to start drawing, the touch panel is touched with a brush while pressing an appropriate key on the computer side, such as a shift switch. Trace, when the cursor appears on the screen, move the cursor to the desired position, then release the key to CR
It was possible to draw on T.

[0003]

In such a conventional touch panel, in order to fix the drawing start point, in addition to tracing the brush on the panel, a predetermined key on the computer side must be operated at the same time. There wasn't. Therefore, if the timing of releasing the key is incorrect, the drawing start point may deviate from the intended position, which makes drawing start very troublesome.
Therefore, the input work efficiency was poor. Further, in the conventional touch sensor input device, the operation on the panel surface has only the meaning of inputting the coordinate position (for example, the relative coordinate position or the absolute coordinate position), and the operator easily grasps the operation on the panel surface. I couldn't. An object of the present invention is to enable an operator to easily grasp the operation time of a point contact operation on a panel surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described below with reference to the drawings.
In FIG. 1, 1 is a CPU (central processing unit), and C
PU1 controls the operation of the entire system described later. CP
A keyboard 2 for input is connected to U1, and output signals of each key of the keyboard 2 are stored in a RAM (random access memory) 3 via the CPU 1. A ROM (read only memory) 4 stores a character generator and a predetermined image pattern in advance. Corresponding data is called by the CPU 1 by the input of the keyboard 2 and is sent via the display control unit 5 and VRAM (video RAM) 6. CR
It is displayed on the screen of T7. The CPU 1 has a panel control unit 9
And a touch panel 10 such as a tablet or a digitizer is connected to the panel control unit 9. The panel control unit 9 includes a brush or the like for designating a position on the touch panel 10. When a point on the touch panel 10 is pressed by this brush, the X and Y position data thereof is digitally detected and the X register 12, Y of the register unit 11 is detected. It is stored in the register 13, respectively.

The register unit 11 is connected to the CPU 1 by a bus line for arithmetic processing of stored data, and is externally connected to the T register 14, the X1 register 15, the Y1 register 16, the N register 17, the X2 register 18, and the Y2.
The register 19 is provided. A cursor display control unit 21 and a frame display control unit 22 are also connected to the CPU 1.
The values of X and Y are given to the cursor display control unit 21,
The cursor pattern retrieved from the ROM 4 is combined with this coordinate value and displayed at the X and Y positions on the CRT 7 screen. In this case, the brush of the panel control unit 9 is the touch panel 1
When it moves over 0, the contents of the X register 12 and the Y register 13 also change, and the cursor position on the CRT 7 also moves according to the movement of the brush. The T register 14 has a keyboard 2 to a CPU 1
The waiting time is specified and stored in units of seconds via. Since the CPU 1 also performs the timing processing by the program from the ROM 4, if the content of the T register 14 is T seconds, for example, C
The PU 1 performs subtraction counting every second (T-1) or every 0.5 second (T-0.5). A predetermined number of dots is designated and stored in the N register 17 from the keyboard 2 via the CPU 1. The number of dots represents the number of pixels on the CRT7 screen. For example, X-N means that a cursor is displayed on the CRT7 screen (value of X) -Nth dot. The CPU 1 subtracts a predetermined number of dots, for example, 6 dots, every second or every 0.5 seconds from the value set in the N register 17. The number of dots to be subtracted for each of these seconds is fixedly determined in advance by inputting from the keyboard 2 to the CPU 1 or by the ROM 4. Setting value of the T register 14 (seconds)
The set value (number of dots) of the N register 17 and the number of dots to be subtracted for each second may be entered as a program from the keyboard 2 in accordance with the operator's proficiency level, or in advance in the ROM.
Alternatively, standard values may be set according to 4. By combining these variables, the stop time of the brush is measured by a timer. In this way, X1 = X-N that changes with time in the X1 register 15, Y1 = Y-N in the Y1 register 16 and X2 = X + in the X2 register 18 are similarly set.
The frame coordinates of Y2 = Y + N are stored in the N and Y2 registers 19, respectively. The frame coordinate values X1 = X-N, Y1 = Y-N, X2 = X + N, Y2 = Y + N are given to the frame display control unit 22, and the frame display surrounded by these straight lines is calculated to obtain V.
It is displayed on the CRT 7 screen via the RAM 6. CPU1
Is the coordinate value of X and Y recorded in the X register 12 and the Y register 13 for a predetermined time or more, for example, 3 seconds or more.
The data is sequentially stored in the memory of the RAM 6. In this way V
The X and Y coordinate values stored in the RAM 6 are constantly displayed on the CRT 7 until the CPU 1 clears all.

Next, the operation of the above embodiment will be described with reference to the flow chart shown in FIG. 2 and FIG. First, the drawing experience on the touch panel 10 is set to 3 seconds in the T register 14 as an average proficiency level (step S1). When a certain position on the touch panel 10 is pressed by the brush of the panel control unit 9, the CPU 1 reads the pressed point coordinate values X and Y, and X
The data is stored in the register 12 and the Y register 13, respectively (step S2). Next, in step S3, N = 36 (the number of dots) is set in the N register 17 in consideration of the display frame being neither too large nor too small and the time limit with respect to the pixel width of the entire screen of the CRT 7. Then, the CPU 1 adds / subtracts N = 36 to / from the pressing point coordinates X and Y, X1 = X−N Y1 = Y−N X2 = X + N Y2 = X + N, and the values of X1 to X2 are X1 register 15, Y1 register 16, The data is stored in the X2 register 18 and the Y2 register 19 respectively (step S4). Based on these calculation results, the frame display control unit 22 generates the index frame W, and the index frame W and the cursor K at the center thereof are displayed on the CRT 7 via the VRAM 6 as shown in FIG. Step S5). T
3 seconds of the register 14 is counted down every 0.5 seconds which is also an average speed (step S6). Next, if the brush moves and the cursor coordinates change (step S
7) and returns to step S1. That is, the CRT 7 displays the index frame surrounding the cursor with the new pressed point coordinates. On the other hand, if the same point is pressed to stop and there is no change in the cursor coordinates, the process proceeds to step S8 and an average of 6 dots, which also affects the stop time limit, is subtracted from N (= 36). C
The PU 1 checks whether the content of the T register 14 has become 0 (3 seconds of the time limit), and if 3 seconds have not yet elapsed, returns to step S4 and calculates new X1 to Y2. Similarly, this is to reduce the indicator frame W by 6 dots from both ends as shown in FIG. On the other hand, when 3 seconds have elapsed, the process proceeds to step S10 and the display frame W is erased from the screen of the CRT 7 (FIG. 3 (c)). Then, the CPU 1 stores the cursor coordinates X, Y and a series of single-stroke X, Y coordinates drawn starting from the cursor coordinates in the VRAM 6 and displays them on the CRT 7 as a line drawing (step S11). The CPU 1 continues to monitor whether or not the brush of the panel control unit 9 is separated from the plane of the touch panel 10, and while the brush is in pressure contact with the touch panel 10, the process returns to step S11 and the display of one stroke is continued on the CRT 7. . Meanwhile, the brush is the touch panel 10.
When is separated from, the current drawing ends, and the next drawing starts from step S1 in the same manner as above.

Considering the above operation on the CRT7 screen shown in FIG. 3, the operation is as follows. That is, when the touch panel 10 is pressed with a brush or the like of the panel control unit 9, the cursor K and the timer display frame W are displayed on the CRT 7 screen corresponding to the position as shown in FIG. 3A. While moving the brush on the touch panel 10 to determine the drawing opening point,
The cursor K and the display frame W on the screen also move on the screen according to the movements. While the cursor frame W is moving as described above, the size of the indicator frame W remains the same as the initial size. However, if the drawing start point is determined by stopping the brush at a certain point on the touch panel 10 for a predetermined period of time, the indicator frame W is displayed. W is gradually reduced (FIG. 3 (b)). After the indicator frame W is erased in this way, FIG. 3C. When the touch panel 10 is traced with a brush, an image corresponding thereto is drawn on the CRT 7 screen. If the brush on the touch panel 10 is moved before the marking frame W is erased, the marking frame W returns to the initial size, and the cursor K moves on the screen of the CRT 7 according to the movement of the brush until the brush is stopped. Moving.

In this way, the CRT 7 is operated without operating the computer side including the CPU 1 and the keyboard 2.
The drawing start point can be determined only by looking at the screen by operating only the touch panel 10 side, and can be accurately determined at the intended place.

The display of the brush stop time is not limited to the display frame W, and a timer scale as shown in FIG. 4 may be displayed. In this case, the brush is pressed on the touch panel to display the band-shaped timer scale 1 at the upper part of the screen (Fig. 4 (a)), and after a few seconds, the inside of the timer scale 1 is filled (Fig. 4 (b)). After the lapse of a predetermined time, it is completely filled and the drawing start point is filled ((c) in the figure). On the other hand, if the brush is moved on the touch panel before the time limit elapses, the timer scale 1 returns to its original position and the cursor K is still in the selected state, as shown in FIG. The cursor K also moves on the screen. This may be represented by another image as long as the brush stop time is visually and intuitively displayed. Various modifications can be made by pre-setting a program for display.
