Abstract

PURPOSE:To allow characters on a screen to easily correspond to panel positions by reading out a keyboard pattern corresponding to a specified character size from a storage means, displaying the read pattern, combining characters inputted to plural keys on the pattern and displaying the combined characters. CONSTITUTION:When the character size is specified by a keyboard 1, a touch panel keyboard pattern corresponding to the character size is read out of a ROM 2 and displayed on a CRT 5. Characters inputted from the keyboard 1 are combined and displayed on a key area positioned by a cursor and the input of data based upon the key operation of a touch panel keyboard is allowed. Consequently, a touch panel keyboard pattern corresponding to the character fonts of plural sizes can easily be formed and the correspondence between the characters on the screen and the positions of the touch panel can easily be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device that has a touch panel as an input means on a display screen of a display means and inputs data using the touch panel.

[Description of prior art and its problems] Conventionally, as a method for inputting data using a touch panel, a touch panel keyboard is used in which a keyboard is displayed on a display screen and data is input by touching a position on the touch panel that corresponds to a key position on the keyboard. There is.

There are two types of touch panel keyboards; one type has keys of a fixed size set in advance, and one keyboard is configured by combining a plurality of keys. Although this touch panel makes it easy to combine a plurality of keys, it has the drawback that a touch panel keyboard cannot be created if the size of the character fonts constituting the plurality of keys changes.

In addition, there was another touch panel that allowed you to change the key size freely, but after changing the size, it required a tedious process to match the characters on the screen with the positions of the keys on the touch panel. There were drawbacks.

[Means and effects for solving the problem] An electronic device according to the present invention has been made in view of the above-mentioned prior art, and includes an input means for inputting character data, and an input means for inputting character data by the input means. a font size specifying means for specifying a size; a size storage means for storing the size specified by the size specifying means; a keyboard pattern storage means for storing keyboard patterns of a plurality of sizes corresponding to the font size; a display means; instruction means for instructing to read and display a keyboard pattern corresponding to the font size specified by the font size specification means from the keyboard pattern storage means; and font size specification in response to the instruction from the instruction means; display control for reading out and displaying a keyboard pattern corresponding to a character size specified by the means from the keyboard pattern storage means, and for displaying a composite of characters input by the input means on a plurality of keys of the keyboard pattern; It is possible to easily create a touch panel keyboard that supports character fonts of multiple sizes, and since the size of the characters displayed on the screen and the size of the keys on the touch panel keyboard are the same, the characters on the screen and the size of the touch panel keys can be easily created. This makes it easy to match positions.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an electronic device according to an embodiment of the present invention.

(2) is a keyboard for inputting character data and numerical data, and also includes a character size designation key for designating the font size of characters to be displayed, a function key for instructing display of the touch panel keyboard, a cursor movement key, etc.

Reference numeral 2 denotes a ROM (read only memory) that stores a control program for the central processing unit CPU, which will be described later, a touch panel keyboard display processing program, character fonts of various sizes, and touch panel keyboard patterns of a plurality of sizes.

Reference numeral 3 denotes a RAM (Random Access Memory) which functions as a work memory for temporarily storing data input from the keyboard and data input from a digitizer DZ to be described later. This RAM also has a video RAM area for storing keyboard patterns and the like to be displayed on a CRT display, which will be described later. Also, 1. In this RAM3,
It also includes a table that stores the character fonts assigned to each key and their display addresses when creating the touch panel keyboard. When the touch panel keyboard is completed, by referring to this table, it becomes possible to input data on the touch position.

4 is an external storage device such as a floppy disk device, in which various data are stored.

5 is a CRT display which is a display device, and on the front of this CRT display is a touch panel.
A transparent resistive film digitizer DZ6 is arranged.

7 is a CPU that controls the main body of this device, and the R
It executes a control program stored in the OM and also executes a touch panel display processing program, which will be described later.

Figure 2 shows the display screen 5 of the CRT display 5 in Figure 1.
FIG. 3 is a diagram showing a touch panel keyboard 8 displayed in FIG.

FIG. 3 is a diagram showing the relationship between character size and touch panel keyboard size. The text font size is (
If i) is selected, a keyboard of size (if) is displayed, and the character font size is (iii).
) is selected, a keyboard of size (iv) is displayed.

Next, the touch panel keyboard display process of the present invention will be explained based on the flowchart of FIG. 4.

In FIG. 4, key input from the keyboard l is first taken in at step Sl. Next, in step S2, it is determined whether the key data taken in is a character size designation key. If it is determined that it is not a character size designation key, the process advances to step S3 and other key processing is performed. If it is determined in step S2 that it is a font size specification key,
In step S4, data of the designated character size is fetched, and in step S5, it is determined whether or not a touch panel keyboard display instruction has been made using a function key.

If no instruction is given, the process proceeds to step S6, where other key processing is performed, and if an instruction is made, a touch panel keyboard pattern corresponding to the font size is read out from the ROM 2 and displayed on the CRT display 5. indicate. In step S8, the characters input from the keyboard 1 are synthesized and displayed in the key area where the cursor is located. Then, in step S9, data input through key operations on the touch panel keyboard is permitted.

In step S2, if the character size is appropriately selected using the character size designation key, a keyboard display as shown in FIG. 3 (ii) or (iv) can be made.

[Effects of the Invention] As explained above, according to the present invention, it is possible to easily create a touch panel keyboard that supports character fonts of multiple sizes, and the size of the characters displayed on the screen and the size of the keys on the touch panel keyboard can be easily created. Since they are the same, it is easy to correspond between the characters on the screen and the position on the touch panel.
