DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an image display device 10 of this embodiment.
FIG.

The image display device 10 is provided in front of the upper surface of the main body 12, and has an input key group 16 including a cursor moving key 13 and a plurality of function keys 14 and the like. A liquid crystal display device 18, which is a body type input device, and a data processing device 20.
(See FIG. 2).

As shown in FIG. 2, the liquid crystal display 18 is a flat panel display, for example, a transparent touch panel 24 for inputting coordinates on the display surface of the liquid crystal display 22.
Are integrated by overlapping, and the screen display and coordinate input are possible on the same screen.

Further, as shown in FIG. 2, the data processing device 20 includes a CPU 26 for controlling the entire device and a CPU 26 for the CPU 26.
RO storing necessary programs such as 26 control processing
M28, RAM 30 for storing data read by the floppy disk drive device 38, coordinate data from the touch panel 24, and the liquid crystal display 22.
Display memory 3 for storing a display image for display on the screen
2, a display control unit 34 of the liquid crystal display 22, a touch panel control unit 36 that controls the touch panel 24 to input coordinates, and read / write data from / to a floppy disk (FD) that stores data as an external storage device. Floppy disk drive (FD
D) 38 and an input key control section 40 for controlling the input key group 14.

The touch panel 24 adopts, for example, a resistance value detection method, and as shown in FIG. 2, resistors are arranged in a matrix at regular intervals in the XY directions. Then, when the touch panel 24 touches a certain position on the touch panel 24 with a predetermined pressing force of its own finger 42 as a touch unit, an intersection (Xn and Yn) of the resistors corresponding to the touched position is scanned. By doing so, the touch position can be found.

Next, the operation of the image display device 10 thus configured will be described with reference to FIGS.
Note that a novel as publishing software is stored in a floppy disk (FD), and the case of reading it will be described.

First, when a floppy disk in which publishing software (a novel) is stored is inserted into a floppy disk drive device (FDD) 38 and a data reading key in the input key group 16 is operated, based on a control program in the ROM 28, The floppy disk drive device 38 reads data from the floppy disk and stores it in the RAM 30. Next, the data stored in the RAM 30 is converted into a display image page by page and sent to the display memory 32, and the read text is displayed on the liquid crystal display 22 for each screen (page).

After reading the displayed text for one page at a desired speed, the finger 42 is touched on the touch panel 24 with a predetermined pressing force, and as shown in FIG. When moved horizontally from right to left (in the direction of the arrow in FIG. 3), the R
The data of the next page stored in the AM 30 is converted into a display image and sent to the display memory 32.
The next page is displayed in 2 (hereinafter also referred to as turning).
On the other hand, when the finger 42 is touched on the touch panel 24 and moved from the left to the right (the direction opposite to the arrow in FIG. 3), the previous page is displayed on the liquid crystal display 22.

At this time, in the touch panel 24,
When the finger 42 touches the upper surface of the touch panel 24 with a predetermined pressing force, the CPU 26 scans Y based on the change in the resistance value of the resistor corresponding to the touch position.
The coordinates (Ys) are detected and stored in the RAM 30 (S1). In this case, since the size of the finger 42 is large, the size of FIG.
When a plurality of Y-coordinates Y11 and Y12 are touched as shown in FIG.
Store in M30. Then, as described above, since the finger 42 is sequentially moving in the arrow direction, at the time of the next scanning, the Y coordinate (Y
n) is detected and stored in the RAM 30 (S2).

Next, Ys stored in the RAM 30
Based on the value of and the value of Yn, it is determined whether the finger 42 is moving leftward or rightward (S3). At this time, if the amount of movement of the finger 42 is small, it is often unclear whether the operator wants to turn the page or not. Therefore, a predetermined amount of movement K is set in advance and the value of Ys is set. If the difference from the value of Yn exceeds the movement amount K, the next page or the previous page is turned over.

Then, when the finger 42 is moving to the left (arrow direction) (S3: YES), it is determined whether the difference between the value of Ys and the value of Yn exceeds the predetermined movement amount K. It is determined (S4), and if the difference is less than or equal to the movement amount K (S4: N
O), the process returns to S2 and the same process is repeatedly executed. On the other hand, if the difference exceeds the movement amount K (S
4: YES), turning the next page, that is, displaying the next page on the liquid crystal display 22 (S5).

When the finger 42 has not moved to the left (S3: NO), Ys stored in the RAM 30 is stored.
And Yn, it is determined whether or not the finger 42 is moving in the right direction (counter arrow direction) (S6). If it is moving to the right (S6: YES), it is determined whether or not the difference between Ys and Yn exceeds a predetermined movement amount K (S6).
7) If it exceeds the predetermined movement amount K (S7: YE
S), turn to the previous page, ie liquid crystal display 2
The previous page is displayed in 2 (S8). If it does not exceed the movement amount K (S7: NO), the process returns to S2 as described above,
Repeat the previous steps. If the finger 42 has not moved to the right, that is, if the value of Ys is equal to the value of Yn (S6: NO), it is determined that the operator has no intention of turning the page. Return to S2. In this way, by performing the same operation of the finger 42 as when reading a normal book, the publishing software (fiction) stored in the floppy disk can be read.

In the above embodiment, the case where the finger 42 is moved substantially parallel to the Y coordinate direction has been described. However, for example, even when the finger 42 is moved to the upper right, the amount of movement is not the actual amount. , The amount of movement in the Y coordinate direction (Ys and Yn
It is sufficient to perform page turning depending on whether or not the difference) exceeds a predetermined movement amount K. That is, the finger 42
The moving direction of is preferably horizontal in view of the determination of the amount of movement, but may be oblique.

The amount of movement (the value of Xs and the value of Xs) in the upward direction (X ₁ direction) or the downward direction (X _n direction) in the X coordinate direction.
Based on whether or not the (difference from the value of n) exceeds a predetermined movement amount K, the next page may be turned over in the upward direction, and the previous page may be turned over in the downward direction.

Further, the number of pages to be turned may be changed based on the number of fingers 42 touching the upper surface of the touch panel 24. For example, when the touch panel 24 is touched with two fingers 42 and is moved from the right to the left by a predetermined amount K or more, as shown in FIG. 5, the displayed pages are turned one after another. Similarly, when the two fingers 42 are moved from left to right by a predetermined amount K or more, the page before the displayed page is displayed. And three fingers 4
If you move the touch surface with 2, you can turn pages one after the other or one after the other.

In this case, there is a region (E1 in FIG. 5) where the two or three fingers 42 are touching the upper surface of the touch panel 24, and the maximum and minimum values of the Y coordinate within the region are detected, If the difference value is 3 or less, one finger 42
If it is set in advance, it is determined that is touched, and if it is 4 to 9, it is determined that two fingers 42, 10 or more are determined to be touched by three fingers 42. Good. Then, this determination may be made in the embodiment S1.

The size of the finger 42 in FIGS. 3 and 5 and the matrix interval of the resistors of the touch panel 24 are not proportional scales.

The present invention is not limited to the above-mentioned embodiments, and various modifications and improvements can be made without departing from the spirit of the invention. For example, in the above embodiment, the publishing software is read into the image display device 10 and displayed,
It may be something other than that.

In the above embodiment, the publishing software is the built-in floppy disk drive device 3 of the image display device 10.
8, the data is read by an external personal computer or a floppy disk life device and the data is read by the image display device 10 as in the prior art shown in FIG.
May be transferred to.

Further, in this embodiment, the page is turned by touching the finger 42 and moving the finger 42 by a predetermined amount. However, even if a previous page key or a next page key which is a dedicated page turning key is provided together. Good. Further, in the present embodiment, the finger 42 is used as the touch means to touch the touch panel, but a protrusion such as a pen may be used as the touch means.

[0032]

As is apparent from the above description, in the image display device according to the first aspect of the invention, the touch means is moved on the surface of the touch panel so that the touch panel moves on the surface according to the touch operation. The direction control data can be output, and the display control means can switch the screen displayed on the display means based on the data.

The image display device according to the invention of claim 2 is
By moving the touch means on the surface of the touch panel, the touch panel outputs data on the amount of movement and the moving direction on the surface according to the touch operation, and if the amount of movement in the moving direction is more than a certain value, it is based on the data. In addition, the screen on the display means can be changed to the previous page or the next page of the displayed screen, and the page can be turned by an operation similar to turning a page of a normal book. Further, when the touch means accidentally comes into contact with the surface of the touch panel, page turning is not performed regardless of the intention of the operator.

Furthermore, in the image display device according to the invention of claim 3, the number of touch means for touching the surface of the touch panel is changed so that the touch panel moves in the direction of movement on the surface and the number of touch means. The data can be output, and based on the data, the number of pages to be turned can be changed in accordance with the number of touch units based on the screen displayed on the display unit.
