Abstract

PURPOSE:To input selectively a processing item while observing a displayed screen, by displaying plural processing items in parallel with a part of the display screen and providing plural touch-key sections corresponding to the display location of the processing item. CONSTITUTION:A common (COM) electrode 2 of a touch key is grounded (GND) at all times, and a COM electrode sinal (e) is at GND level. When an item electrode 3-1 is depressed, for example, the COM electrode 2 and the item electrode 3-1 are short-circuited and an item electrode signal (f) goes to L. While the touch key is depressed, a detecting circuit 5 output a detecting signal (c), a strobe signal (o) and an interruption signal (d) to a CPU. An interface circuit 6 stores the signal (c) with the signal (o). The CPU receives the signal (d), outputs a readout signal (b) and reads the detected content. The content stored in the interface circuit 6 is outputted to a micro-bus (a).

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to devices such as Japanese word processors, office computers, and personal computers that are equipped with a display device, a keyboard, and a main unit that performs necessary processing. Creation of.

Proofreading 9 When editing, printing, registering, recalling, etc.

This invention relates to a device for selectively inputting various processing items.

Conventional configurations and their problems In recent years, the development of Japanese word processors and office computers has been remarkable, and demand is rapidly increasing. Under these circumstances, devices are becoming more and more multi-functional, and there is a desire to develop devices that can be easily used even by beginners in terms of operating procedures.

FIG. 1 is a diagram showing an example of an editing function and an input function among the functions of a Japanese word processor. In order to make a Japanese word processor perform these functions, the functions must be selected and processed by some means. Conventionally, as a means for selecting this function, a function switch (hereinafter abbreviated as function key) was placed on the keyboard, and the function was selected by pressing this switch. FIG. 2 shows an example of function keys arranged on the keyboard.

Editing function The underline (underline) can be added or deleted, and 2.
A fixed function key is required. It is convenient to have multiple functions, but not only do the number of function keys increase on the keyboard, but beginners have a hard time just finding which function keys are placed where, and functions that are supposed to be useful end up being difficult to use. It comes out. Because there are so many hidden keys, the cost of the keyboard is also high.

Next, a conventional example of selecting an item will be described. FIG. 3 shows an example of the display. This is an example of a message displayed when [Register] of the function keys shown in FIG. 2 is pressed. The upper part of the display screen is used as a text display area, and the lower part is used as a message display area. In the example, "temporary registration" means to temporarily store previously created sentences, etc., and "floppy" means to store created communications to a FRONB sheet.

When the machine key [Register] is pressed, the message display area becomes as shown in Fig. 3, and the user must select between temporary registration and floppy storage.

In this case, the method for temporary registration is °′1”
If you want to specify it as a floppy disk, you input ``°2'' from the keyboard, and then press the [Execute/Yes] key to finish the input and make your selection.

The operation at this time is a two-stroke operation of pressing a number and pressing the [Execute/Yes] key. Also, after looking at the items on the display screen and selecting them, you have to search for numbers on the keyboard and enter them, and if you repeat this operation many times, your eyes will get tired. Furthermore, there was a problem in that work efficiency was also reduced.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and provides an input device that achieves full multifunction without increasing the number of function keys arranged on the keyboard, and allows easy selection of items with less fatigue. The purpose is to

Structure of the Invention The present invention includes a display unit that displays a plurality of processing items in parallel in an item display area provided in a part of a display screen, and a display unit provided on the display screen corresponding to the display position of the processing items. It is equipped with a transparent switch section consisting of a plurality of transparent switches (hereinafter abbreviated as touch keys), and it is possible to selectively input processing items by touching the transparent switch at the position where the item to be processed is displayed. .

DESCRIPTION OF EMBODIMENTS FIG. 4 shows a configuration diagram of an input device in an embodiment of the present invention. In Fig. 4, 1 is the display screen, 2 is the common (COM) electrode of the touch key, and 3-1 to 3-8 are the touch key items located at positions corresponding to each item. Electrode 2 and item electrode 3 are shorted.

4 is a transparent sheet for attaching the sliding door 2 and the item electrode group 3; 5 is a detection circuit that detects which electrode of the item electrode group 3 is pressed; and 6 is a CP reader for importing the detection information into the CP controller, etc. / interface circuit, the detection signal of output from the detection circuit 6, the strobe signal indicating that the touch key is pressed (held by ψ, ■ is Cpt
Microbus such as J, ■ is read signal, ■ is CpLJ
etc., is an interrupt 1 word to notify that a touch key has been pressed, ■ is a COM electrode signal, and ■ to 0 are item electrode signals. FIG. 6 shows a signal waveform diagram of each part.

FIG. 6 shows an example of a circuit for generating the strobe signal (K) and interrupt signal (2) in the detection circuit 6. 11 is an OR circuit that outputs a signal while the item electrode group 3 is pressed, and the item electrode signal ■
When any one of ~■ is low, all OR signal signals are output. 12 is a chuckling prevention circuit for eliminating the influence of chattering of the transparent switch, and outputs a chattering prevention signal (2). 13 is a strobe generating circuit which generates a pulse signal (2) which becomes an id strobe signal (@) or an interrupt signal (2); and 14 is a NAND circuit which generates a strobe signal (@) or an interrupt signal (@) while the transparent switch is pressed. FIG. 7 shows a signal waveform diagram of each part.

Book 8 shows an example of the display screen of the display unit. The upper part is a text display area, and the lower part is an item display area for touch keys. In this embodiment, the item can be displayed as 8f. “′・” is a mark indicating the boundary between items. The underline of one character below the character indicates the cursor position (the "most position" in FIG. 8).

The operation of this embodiment will be explained below.

The GOM electrode is connected to (, ND. The COM electrode signal ■ is at the CHD level. Now, suppose that the item electrode 3-1 is pressed. The 00M electrode 2 and the item electrode 3-1 are short-circuited, and the item The electrode signal ■ becomes ``L'' (Fig. 6, period tf).
'' (FIG. 7) When the 00R signal @ falls, the chuckling prevention circuit 12 is driven and outputs a signal at HI+ level during the period tl as the chattering prevention signal ■. The period t1 is set longer than the chuckling time of the touch key. The strobe generating circuit 13 is driven by the fall of the chattering prevention signal (2), and outputs the pulse signal (2) for the period t2. Since chattering occurs when a touch key is pressed and released, the chattering prevention signal ■ and pulse signal ■ are output at the rise and fall of the ORj word @. The pulse signal ■ is output by the NAND circuit 14 as a strobe signal @ and an interrupt signal ■ only while the touch key is pressed (Fig. 7).
.

The detection circuit 6 outputs the sign @ during the period when the touch key is pressed (FIG. 6, f of @). 11. At the same time, a strobe signal @ and a touch key are sent to the CPU, etc. indicating that the touch key has been pressed. The 0cpu interface circuit 6 that outputs the input signal 1* outputs the detection signal @ at the falling edge of the strobe signal @.
hold. When the CPU detects an interrupt signal @ all bones, it outputs a read signal bl and reads the detected content sound. At this time,
The contents (2) held in the CPU interface circuit 6 are output to the microbus (2). Detection signal @ is CPU
An interrupt is generated at the rising edge of the interrupt signal @ so that the read word (2) is output after being sufficiently held in the innocuface circuit 6.

When the item electrode 3-2 is pressed, the item electrode becomes L I+ during the period of tg when the return signal ■ is pressed.Item electrode 3-
Similarly, when 1 is pressed, the detection circuit 5 outputs the detection signal ■ (6th
In addition to outputting the strobe signal @ and the interrupt signal @, When the strobe signal @ falls, the CPU interface circuit 6 holds the content g of the detected one word (2). A 1 is read into the CPU by the read signal ■.

The same is true when the item electrode 3-5, 3-8 is fully pressed (FIG. 6, period tm).

In this way, it is possible to detect when the touch key 1 has been pressed.

FIG. 8 is a first display example of the display screen of the display section, in which processing items are displayed in the item display area. As an example of processing items, all key items of opportunity are displayed in the edit mode.

Hereinafter, touch keys are indicated by 0 to distinguish them from keys on the keyboard. Set the 8th item to Other,
When (Others) is pressed, another function key item is displayed instead. Since only eight items can be displayed, this is to allow them to be displayed one after another.

Explain when to underline. Press (Others) to call up the display screen where arm> is displayed in the function key field. FIG. 9 shows the display screen side. After calling the display screen, move the cursor to the beginning of the character string you want to underline (in the example, the end) and press (underline). Next, move the cursor to the end of the character string you want to underline (0.1 in the example). You can change the underline by moving and pressing (underline). In the above case, you would have to press (other) many times to display the desired function key item. Therefore, the display screen for function key items can also have a directory structure.

FIG. 10 shows an example of a display screen in the case of the direct IJ-structure, and the case where underlining is performed will be explained.

First, in Figure 8, ``the beginning of the character string that you want to underline (
In the example, move the cursor to ")" and press (Specify Area).Then, the item display area will become as shown in Figure 10.
Machine key items for specifying the area will be displayed. Next, move the cursor to the end of the character string you want to underline (+1.n in the example) and press (underline). This operation allows you to underline. By using a directory structure, the display screen for the desired function key item can be quickly called up. Furthermore, the operation for underlining can be performed with two strokes: (area specification) and (underline), which reduces the number of touch key presses (b).

Next, the registration operation explained in the conventional example (FIG. 3) will be explained. When (Register) is pressed in FIG. 8, the item display area is displayed as shown in FIG. 11. If you want to temporarily register (temporary registration), if you want to register on a floppy sheet, click (
floppy).

If it is a conventional keyboard operation, all you need to do is 3 strokes (Register), [Numeric], and [Execute], followed by two consecutive strokes (Register), (Temporary Registration), or (Floppy), and select the key. By doing so, work efficiency will increase.

In addition, although it was explained using 8111iI as the number of keys,
There is no limit to the number. Furthermore, although the lower part of the display screen is used as the touch key item display area, it does not need to be the lower part at all. The touch key item display area may be the upper half, the lower half, or the entire screen.

Although the explanation has been made using a switch having a 00M electrode as a touch key, a transparent switch using a capacitance detection method or a no-mu detection method may also be used.

Effects of the Invention The present invention provides a display section that displays a plurality of processing items to be processed by a main unit in parallel in an item display area provided in a part of a display screen, and a plurality of processing items that are displayed in the item display area. The keyboard is constructed with a transparent switch section consisting of a plurality of transparent switches provided on the optical display screen corresponding to the display positions of the items, so the number of keys on the keyboard can be reduced, resulting in a low-cost keyboard. 1) You can select items while looking only at the display screen, rather than operating while looking at both the display screen and the keyboard, as in the past, so it is less tiring. The number of strokes can also be significantly reduced. Furthermore, since it can be made into a directory structure, it has great practical effects such as being highly extensible.
