Abstract

PURPOSE:To attain input operation by one hand by providing a means generating a shift code only for the next touch through the depression of a shift key. CONSTITUTION:A key arrangement 21 comprising keys 41 on which character/ numeral/symbol are engraved and generating them by depression is arranged on a keyboard plane 11, a depressedkey No is fetched to a keyboard driver and a prescribed code is generated. Keys 32-35 are shift lock keys holding a specific code generating mode through depression and a key 31 is shift key causing a prescribed code generating mode only at depression. The keys 41 engraved with character symbols 110, 120-150 generates a corresponding character code according to the depressing state of the keys 31-35. When only the shift key 31 is depressed singly, a code of a prescribed shift mode is generated independently of the mode under shift lock for one touch of the key 41 depressed succeedingly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for generating key codes input from a keyboard, and particularly to a key input method for easily inputting function codes on a general-purpose JIS layout keyboard. .

[Background of the invention]

The keyboards of computer terminals, personal computers, word processors, and multifunctional workstations that have these functions on one terminal are JIS layout keyboards (Japanese Standards Association: JIS Handbook Information Processing, p. 52).
8 to 534), which has function keys used for applications such as word processors as a group of independent function keys (Newton magazine special issue: All about word processors: P46), assigns function keys to JIS layout keys, What to select with the shift key for function keys (newly manufactured by Hitachi: 1 (ITACT56)
There is also a manual for Unit 0/20 (P54). However, providing independent function keys on the keyboard tends to make them exclusive for each specific application, and also tends to increase the surface area of the keyboard to be operated. On the other hand, in order to input function keys using the function shift key on a general-purpose keyboard, it is necessary to use both hands at once, which significantly reduces operability when amateurs input and edit Japanese with a manuscript in front of them. do. In such cases, it would be very convenient to be able to press a function key with just one hand.

[Purpose of the invention]

An object of the present invention is to provide a means for selecting and generating character codes and function codes assigned to a JIS layout keyboard by pressing the shift key and the corresponding key in sequence, thereby allowing easy Japanese input/editing with only one hand. The purpose is to perform function key input in applications such as

[Summary of the invention]

Conventionally, in order to substitute a function key with the JIS layout keys on a general-purpose keyboard, it was necessary to press the key together with the function shift key to generate a code, which was difficult to operate because both hands were used, and it was difficult to use while holding the original. Typing was difficult. Therefore, in the method of the present invention, when a normal shift key is pressed, a means is provided to generate a shift code for the next one touch, and when a shift key and a data key are pressed in sequence, the function code assigned to the data key is generated as a shift code. This feature is characterized by the fact that the key input method is generated, and provides a highly operable key input method that can be input with one hand.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4.

FIG. 1 shows a keyboard device to which the present invention is applied. On the keyboard surface 11, a key arrangement 21 consisting of keys 41 inscribed with letters, numbers, and symbols that are generated when pressed is arranged in accordance with, for example, the JIS layout, and the key number to be pressed is determined by the keyboard driving device. (not shown) and generates a predetermined code. The keyboard drive then changes the codes generated by the keys 31-35. Keys 32, 33, 34, and 35 are shift lock keys that each hold a specific code generation mode when pressed, and key 31 is a shift key that enters a predetermined code generation mode only when pressed.

FIG. 2 shows keys 31, 32, 33 . on the keyboard.
A key 41 is shown with character symbols 110, 120, 130, 140° 150 engraved thereon which switch depending on the pressed state of keys 34 and 35. The shift lock key 32 is already pressed and the shift lock key 33

40 respectively. The engraving 150 mainly indicates functions such as "correction" and "movement". Conventional keyboard 11
The function 150 is activated by pressing the key 41 at the same time as a function selection shift key (not shown) provided separately above. On the other hand, in the present invention, when the shift key 31 is pressed alone, the function 150 can be selected by generating a predetermined shift mode code regardless of the mode in which the shift is locked, with just one touch of the subsequently pressed key 41. shall be.

The process of code generation will be described in detail below in accordance with the flowcharts of FIGS. 3 and 4.

In this embodiment, a one-touch shift switch is provided, and the switch is controlled by pressing a key, and when the switch is turned on, the stamp 150 is generated, and when the switch is turned off, a conventional code is generated. The key 41 pressed on the keyboard 11 is read into the keyboard driving device in block 300, and when the one-touch shift switch is in the OFF state, a key code is generated according to the procedure shown in FIG. The pressed key is identified by the key number, and if the only pressed key is the shift key 31, the one-touch shift switch is turned on in block 340, and the key input process ends. If the pressed keys are the shift key 31 and the key 41, in block 320, the shift code 110 or 1 corresponding to the input mode created in advance by pressing the shift lock key 32 or 33 is entered.
Generate 40. When the key pressed is the shift lock key,
At block 310, a corresponding shift lock mode inversion is performed. If the only pressed key is the data key 41, in block 330, a non-shift code 120 or 130 corresponding to the input mode previously created by pressing the shift lock key 32 or 33 is generated.

On the other hand, when the one-touch shift switch is on, the fourth
Generate a key code using the steps shown in the figure.

When the one-touch shift switch is on, the one-touch shift switch is always turned off in response to a meaningful key press, and then the key input process ends.

When only the shift key 31 is pressed, no code is generated, and the one-touch shift switch is turned off in block 440, thereby ending the key input process. When the shift key 31 and data key 41 are pressed, and when the shift lock keys 32 to 35 are pressed, the same code as in the one-touch shift lock switch off state in FIG. 3 is generated, and one-touch shift is performed in block 440. Turn off the switch. When only the data key 41 is pressed, the function code 150 is generated in block 430 regardless of the shift lock mode, and then the one-touch shift switch is turned off in block 440. That is, in the present invention, a key input procedure is realized in which the shift key 31 and the key 41 are pressed individually and successively, without using the shift key for function selection.

Function code 150 can be generated using only the shift key. At this time, if you press the shift key 31 and key 41 at the same time, the shift code will not be a one-touch shift, but will follow the mode in which the shift is locked, and if you press only the shift key continuously, the one-touch shift mode will not be activated. , without compromising the conventional key input procedure.

〔Effect of the invention〕

According to the present invention, by effectively using a shift key that conventionally does not function alone, it is possible to easily select a function, thereby improving operability. In particular, since functions can be selected by pressing the shift key and a desired key in sequence, input operations for functions that conventionally required both hands can be easily performed with only one hand. In addition, operations other than function input are completely different from conventional operations, so there is no feeling of discomfort in operation.
