Description

 The present invention relates to an apparatus for inputting data from a keyboard or the like to a personal computer or a portable information device.

  A keyboard having 26 alphabets arranged as a QWERTY key layout is widely used as a data input means for personal computers and portable information devices.

  For example, on a standard personal computer capable of processing Japanese, 26 alphabets are arranged in a QWERTY key layout, and numbers / symbols and other keys are added, and 109 keys as shown in the schematic diagram of FIG. A keyboard that accepts various keystrokes is used. Further, the shift key (1691) or the shift key (1703) in FIG. 16 is used to increase the types of characters that can be input such as uppercase letters.

However, these shift keys are provided so as to be operated while being pressed with the left and right little finger keys, and the same operation is performed on the left and right as key code input.
On the other hand, products such as M-type key arrangement made by NEC and thumb shift input made by Fujitsu that can efficiently perform Japanese key input more than the QWERTY key arrangement are commercially available. These are provided with a function of performing two different shift operations for the two thumb shift keys corresponding to the left and right thumbs. These keyboards also have a total number of keys of about 100.

However, these thumb shift keys simply change the position of the left and right little finger shift keys as the thumb shift keys, so the types of characters that can be input with the shift keys do not increase significantly compared to conventional ones. .
Japanese Patent No. 1546214 Japanese Patent No. 1441829 “This is the best keyboard for Japanese,” pages 43-44, written by Masanori Morita, Nikkei Inc., March 1992 Proceedings of the 20th National Convention of the Information Processing Society of Japan in 1979, “Thumb Shift Keyboard”, page 675 Yasunori Kanda

  The problem to be solved by the invention is that the number of keys is about 50 smaller than that of a conventional keyboard with about 100 keys, which is standardly used in a personal computer as shown in the schematic diagram of FIG. It is an object of the present invention to provide a keyboard that is improved in efficiency, efficient in operation and excellent in operability while maintaining compatibility and affinity in operation with a conventional keyboard.

  Increase the number of shift states to reduce the number of keys on the keyboard. That is, before pressing the data key while shifting (hereinafter, key pressing refers to a series of actions of pressing and releasing the key), if the shift key is pressed and the data key is not pressed and the shift key is released, Change the shift state.

  By repeating the operation of pressing and releasing the shift key n times, the shift state may be increased by n before the data key is pressed and the key is input while pressing the shift key.

  For convenience of operation, when the data key is pressed in a specific shift state without pressing the shift key, only one key input is performed in the shift state, and the shift is performed. The state may be released.

  To make it easier to operate the shift key with the left and right thumbs, two shift keys are provided to increase the number of shift states, and alphabet keys can be used to enter lowercase letters, uppercase letters, numbers, symbols, and functions. May be.

  By using the fact that the number of key codes that can be input can be increased by increasing the number of shift states, key-saving key input can be performed in combination with software.

  When different key codes are input in the same key shift state, a key map that is convenient for the operation distinguished in the shift state may be displayed on the display device of the electronic device.

  The first effect of the present invention is that the number of keys on the keyboard can be reduced and a space-saving keyboard can be realized. This is because the same key can be efficiently used to input a plurality of types of key codes by thumb shift in multiple stages on the left and right.

  The second effect is that the key input speed does not decrease as a whole despite the keyboard having a small number of keys. This is because the finger movement distance is short because the number of keys is small, and the movement time of fingers other than the thumb is short, and the thumb shift in multiple steps does not require the thumb movement time, and the overall speed does not decrease. It is.

  The third effect is that a keyboard that can be easily touch-typed including the numbers and symbols of the keyboard can be realized. This is because the shift operation can be smoothly performed with the thumb without imposing a large burden on the little finger in addition to the key arrangement with a small finger moving range with a small number of keys.

  The fourth effect is the smooth movement of the uppercase alphabetic characters, which was previously performed with the little finger, with the strong thumb, reducing the burden on the little finger, and fatigue when inputting keys in English for a long time. Can be reduced.

  The fifth effect is that it is possible to efficiently realize key-saving key input that allows a plurality of key code strings to be input with one key pressing. This is because many types of key code strings can be realized with simple keystrokes by the left and right multi-stage thumb shift functions.

  The sixth effect is that a key-saving key can be input efficiently using a dictionary. This is because a device for properly combining a dictionary function originally provided in a personal computer or the like with a left and right multi-stage thumb shift function has been devised.

  The seventh effect is that even a beginner can input many types of characters and character strings with little mistake. This is because key operations can be performed according to a key map appropriately displayed on the operation screen by software installed on a personal computer or the like.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a keyboard used in the first and second embodiments of the present invention. This keyboard is composed of 48 keys arranged in a 4 × 12 grid. This keyboard is connected to a USB interface of a personal computer, and a character key code corresponding to the key pressed by the operator is sent to the personal computer for key input.

  15 characters of alphabet keys are arranged in three lines from the top of the left half. Similarly, 11 characters and 4 symbols are arranged in the other three alphabet keys from the top of the right half. The alphabet array is arranged in a so-called QWERTY array, and is an array that is standardly adopted for keyboards of electronic devices such as personal computers.

  The three keys arranged in the center of FIG. 1, ie, the switching number / key (116), switching character key (136), and switching function key (156) are keys for switching the state of the keyboard of FIG. Lamps are embedded in the key tops of these keys, and when these keys are pressed, the lamps are turned on and the respective keyboards are set. In the initial state, the character key is pressed.

  Twelve control keys are arranged at the bottom of the keyboard in FIG. 1, and three control keys are arranged at the top three of the right end.

  In the character state of the keyboard shown in FIG. 1, character keys are input to the personal computer in accordance with the key layout shown in FIG.

  In the character state or function state of the keyboard of FIG. 1, when the switching number / key (116) is pressed, the keyboard of FIG. 1 becomes the number / key state of FIG. A numeric key is entered. In the number / state, some keys are assigned function keys.

  When the function key (156) is pressed in the number / state or character state of the keyboard of FIG. 1, the keyboard of FIG. 1 enters the functional state of FIG. 3, and the function key input to the personal computer is performed according to the key arrangement of FIG. Is done. Note that, in the function state, the number that is input is usually a number that is input using the numeric keypad, and is distinguished from a numeric key code that is not a numeric keypad in the number / notation state.

  As described above, by switching the keyboard of FIG. 1 and using it as FIG. 2 and FIG. 3, the key input equivalent to a full keyboard of 109 PCs can be obtained even though the number of keys is as small as 48. it can. However, the function key related to the numeric keypad called NumLock key is not necessary because it is not necessary.

  In the embodiment of the present invention, a keyboard as shown in FIG. 1 is used as hardware, and special software (hereinafter referred to as software A) is installed in the personal computer, thereby simplifying character string input to the personal computer. Increase efficiency.

  Software A is utility software combined with a keyboard driver, which runs on a personal computer and converts key code input to the personal computer according to the status and specified information. Alternatively, operation guide information called a key map is displayed on the personal computer screen.

  The non-conversion key (175) in FIG. 1 is used as a left thumb shift key, and the conversion key (177) is used as a right thumb shift key for changing the shift state. The operation at this time will be described in the following embodiments.

    In the initial state where the software A is activated and operating, the state of key input to the personal computer of the keyboard of FIG. 1 is the state of FIG. 4 shows a character input state. In FIGS. 4 and 1, the key arrangement is the same except for the left thumb shift key (475) and the right thumb shift key (477) in FIG.

By the operation of the software A, the key (175) in FIG. 1 that has been operated as the non-conversion key (1714) in FIG. 16 operates as the left thumb shift key (475). Similarly, the key (177) of FIG. 1 that has operated as the conversion key (1718) of FIG. 16 operates as the right thumb shift key (477).

  In FIG. 4, when another key is pressed while pressing the left thumb shift key (475), a key code corresponding to the character arrangement of FIG. 5 is sent to the personal computer corresponding to the key pressed (left thumb shift key ( If the pressing of 475) continues, the state of FIG. 5 continues).

  Alternatively, in FIG. 4, when the left thumb shift key (475) is pressed, no other key is pressed, the left thumb shift key (475) is stopped, and then another key is pressed, the character arrangement of FIG. After the key code corresponding to is sent to the personal computer, the state returns to the state of FIG. The state of the keyboard in FIG. 5 is referred to as a left α shift state.

  Next, in FIG. 4, when the right thumb shift key (477) is pressed and another key is pressed (here, key pressing refers to a series of actions of pressing and releasing the key), corresponding to the key pressed, A key code corresponding to the character arrangement of FIG. 6 is sent to the personal computer (if the right thumb shift key (477) is continuously pressed, the state of FIG. 6 continues).

Alternatively, in FIG. 4, when the right thumb shift key (477) is pressed, no other key is pressed, the left thumb shift key (475) is stopped, and then another key is pressed, the character arrangement of FIG. After the key code corresponding to is sent to the personal computer, the state returns to the state of FIG. The state of the keyboard in FIG. 6 is referred to as a right α shift state.

  Next, in FIG. 4, the left thumb shift key (475) is pressed, no other keys are pressed, the left thumb shift key (475) is stopped, and then the left thumb shift key (475) is pressed, When another key is pressed, a key code corresponding to the character arrangement shown in FIG. 7 is sent to the personal computer corresponding to the key pressed (if the left thumb shift key (475) continues to be pressed, the shift state shown in FIG. Will continue).

  Alternatively, in FIG. 4, the left thumb shift key (475) is pressed, the other thumb is not pressed, the left thumb shift key (475) is stopped, and then the left thumb shift key (475) is pressed. Stop pressing the left thumb shift key (475) without hitting any other key, and hit another key to return to the state shown in FIG. 4 after the key code corresponding to the character arrangement in FIG. 7 is sent to the personal computer. . The state of the keyboard in FIG. 7 is referred to as a left β shift state.

  Next, in FIG. 4, the right thumb shift key (477) is pressed, the other thumb is not pressed, the right thumb shift key (477) is stopped, and then the right thumb shift key (477) is pressed, When another key is pressed, a key code corresponding to the character placement shown in FIG. 8 is sent to the personal computer (if the right thumb shift key (477) is continuously pressed, the state shown in FIG. continue).

  Alternatively, in FIG. 4, the right thumb shift key (477) is pressed, no key is pressed, the right thumb shift key (477) is stopped, and then the right thumb shift key (477) is pressed. Stop pressing the left thumb shift key (475) without hitting any other key, and hit another key to return to the state shown in FIG. 4 after the key code corresponding to the character arrangement in FIG. 8 is sent to the personal computer. . The state of the keyboard in FIG. 8 is called a right β shift state.

  Here, the meaning of the state of the keyboard shown in FIGS. 4, 5, 6, 7, and 8 will be described.

  In the state of FIG. 4, except for the left thumb shift key (475) and the right thumb shift key (477), the state is the same as in FIG. 1, and an alphabet and some symbols are input.

  In the state of FIG. 5, uppercase letters (right half of QWERTY key arrangement) and some symbols are input in the right half of the keyboard, and symbols and some control keys are input in the left half.

In the state of FIG. 6, numbers and some symbols are input in the right half of the keyboard, and upper case letters (the left half of the QWERTY key arrangement) are input in the left half.

In the state of FIG. 7, numeric keys and some symbols are input in the right half of the keyboard, and shift symbols are input in the left half.

  In the state of FIG. 8, shift numbers are input in the right half of the keyboard, and function keys are input in the left half.

  4, 5, 6, 7, and 8, key input that is the same as that of FIGS. 1, 2, and 3 can be performed, and alphabetic capital letter key input can be performed.

Next, some examples will be described.
For example, in the state shown in FIG. 4, when the data key a (431) is pressed with the left little finger, the data key s (432) is pressed with the left hand ring finger, and the data key k (439) is pressed with the middle right finger. The column “ask” is entered.

  Similarly, for example, in the state of FIG. 4, the right thumb shift key (477) is pressed with the right thumb, and in the state of FIG. 6, the data key A (631) is pressed with the left little finger, and the right thumb shift key (677) is released. In the state shown in FIG. 4, when the data key s (432) is pressed with the left little finger and the data key k (439) is pressed with the middle left finger, the character string “Ask” is input.

  Similarly, for example, in the state of FIG. 4, the right thumb shift key (477) is pressed with the right thumb, then the right thumb shift key (677) is released in the state of FIG. 6, and in the state of FIG. When the data key A (631) is pressed, and in the state shown in FIG. 4, the data key s (432) is pressed with the left-hand ring finger and the data key k (439) is pressed with the middle finger of the right hand, the character string “Ask” Entered.

  Similarly, for example, in the state of FIG. 4, the right thumb shift key (477) is pressed with the right thumb, and in the state of FIG. 6, the data key A (631) is pressed with the left little finger, and the right thumb shift key (677) is released. In the state of FIG. 4, the data key s (432) is pressed with the left hand ring finger, the data key k (439) is pressed with the middle finger of the right hand, the left thumb shift key (475) is pressed with the left thumb, and then , Release, press again, release, in the state of FIG. 7, with the left little finger, the data key? When the user presses (751), the character string “Ask?” Is input.

  Similarly, for example, in the state of FIG. 4, the right thumb shift key (477) is pressed with the right thumb, and in the state of FIG. 6, the data key A (631) is pressed with the left little finger, and the right thumb shift key (677) is released. In the state of FIG. 4, the user presses the data key s (432) with the left hand ring finger, hits the data key k (439) with the middle finger of the right hand, and presses the right thumb shift key (477) with the right thumb. In the state of 6, the data key number 1 (658) is pressed with the right index finger, the data key number 5 (639) is pressed with the middle right finger, and the data number key 7 (618) is pressed with the right index finger. The character string “Ask157” is input.

  In the above example, the finger operation method is performed by an efficient method called touch typing. In particular, the left and right thumbs do not need to move each time a key is pressed at the same key position.

  Next, key map display as guide information for the operator will be described. Software A displays the key map on the display screen of the personal computer. The contents of the key map can be set as appropriate by the user of the software A.

  For example, the state of the keyboard in FIG. 5 is displayed in a 3 × 10 grid frame as shown in FIG. 11. The display is performed on the grid portion corresponding to the alphabet keys in FIG.

For example, the display of FIG. 11 is displayed corresponding to the state of FIG. 5 when the left thumb shift key (475) is pressed in the state of FIG. When the operator views the key map frame H (1136) displayed in FIG. 11 and presses the data key H (537) in FIG. 5, the character H is input.
Note that the key map display is not necessary if the operator memorizes the operation method, and can be turned on and off as needed by the operator.

Next, we will describe the keystroke input for character strings using a personal computer dictionary. A personal computer is equipped with a key-saving key input function for character strings.

  For example, if “Shodaki” is input as the “saving key input function” and “space” key and “Enter” are pressed, “saving key input function” is input. For this purpose, it is necessary to register “shodaki” as “reading” and “saving key input function” as an input character string in advance in the dictionary of the personal computer. As for “reading”, it is desirable to select an input that is not often used.

By using this function, an efficient key-saving method is realized as follows.
In the state of FIG. 4, the state in which the left thumb shift key (475) is pressed twice and the left thumb shift key (475) is pressed or the left thumb shift key (475) is pressed three times is the state in FIG. It is.

At this time, when the data key \ ^ 1 (911) is pressed, the software A identifies the key code corresponding to the data key \ ^ 1 (911) and converts it to a key code string corresponding to the character string "\ ^ 1". Then, key input is performed, and subsequently, a “space” key and a key code of “Enter” are input. At this time, if “¥ ^ 1”, which is not usually used as a reading, is registered in advance as an input character string in the above-described dictionary, a character string “saving key input function” Is entered.

Similarly, the other keys in FIG. 9 can register a total of 30 types of character strings “¥ ^ n (n is 2 to 30)”.

FIG. 12 is displayed as the key map, and the key map frame saving machine (1211) frame is set with an easy-to-remember slogan, for example, “saving machine”. The other frames in FIG. 12 are also set according to the contents of the dictionary.

Similarly, in the state of FIG. 4, the state where the right thumb shift key (477) is pressed twice and the right thumb shift key (477) is further pressed, or the state where the right thumb shift key (477) is pressed three times is shown in FIG. 10 states.

  At this time, when the data key \ = 1 (1011) is pressed, a key code string corresponding to the character string "\ = 1" is input, and then a "space" key and a key code of "Enter" are input. . If the input character string “¥ = 1” which is not normally used as a reading is registered in advance in the above dictionary, the registered input character string is input.

Similarly, the other keys in FIG. 10 can register a total of 30 types of character strings “¥ = n (n is 2 to 30)”.
A slogan that is easy to remember is set as the key map.

  This embodiment provides a key-saving key input method that is effective when inputting Japanese.

In Example 1, an uppercase letter was input using the left / right thumb shift, but in this example,
Allows effective abbreviated keystrokes for kana romaji instead of alphabetic capital letters.

  13 and 14 are replaced instead of FIGS. 5 and 6 of the first embodiment.

  In FIG. 4, when the left thumb shift key (475) is pressed and another key is pressed (here, the key pressing refers to a series of actions of pressing and releasing the key), corresponding to the key pressed in FIG. A key code corresponding to the character arrangement is sent to the personal computer (if the left thumb shift key (475) continues to be pressed, the state of FIG. 13 continues).

  Alternatively, in FIG. 4, when the left thumb shift key (475) is pressed, no other key is pressed, the left thumb shift key (475) is stopped, and then another key is pressed, the character arrangement of FIG. After the key code corresponding to is sent to the personal computer, the state returns to the state of FIG. The keyboard state in FIG. 13 is referred to as a left α shift state.

  Next, in FIG. 4, when the right thumb shift key (477) is pressed and another key is pressed (here, key pressing refers to a series of actions of pressing and releasing the key), corresponding to the key pressed, A key code corresponding to the character arrangement in FIG. 14 is sent to the personal computer (if the right thumb shift key (477) continues to be pressed, the state in FIG. 6 continues).

  Alternatively, in FIG. 4, when the right thumb shift key (477) is pressed and no other key is pressed, pressing of the right thumb shift key (477) is stopped, and then another key is pressed, the character arrangement of FIG. After the key code corresponding to is sent to the personal computer, the state returns to the state of FIG. The state of the keyboard in FIG. 6 is referred to as a right α shift state.

  In the state of the keyboard shown in FIGS. 13 and 14, “Y” is added to the Roman consonant. For example, when the data key KY (1339) in FIG. 13 is pressed, the character string “KY” is input. Subsequent to “KY”, for example, “A” is input and a roar “Kya” is obtained. Roaring is frequently used in Japanese.

  “NN” is added to Roman vowels. For example, when the data key ANN (1431) in FIG. 14 is pressed, the character string “ANN” is input and the sound repellent “An” is obtained. Sound repellent is also frequently used in Japanese.

  In FIG. 13, composite vowels “AI”, “EI”, “OU”, and “OI” are arranged. These composite vowels are also frequently used.

  The above key input is a two-touch key input together with the left and right shift keys, but the left and right shift keys and the alphabet keys can be touched simultaneously, and a key-saving effect is obtained.

  The key input method according to the state of the keyboard in FIGS. 13 and 14 is a method known as M-type key input suitable for Japanese input (see Non-Patent Document 1 “This is the best keyboard for Japanese”), Is applied to an embodiment of the present invention.

  The states of the keyboards in FIGS. 4, 7, 8, 9, and 10 other than FIGS. 5 and 6 are the same as those in the first embodiment.

  Note that this embodiment mainly assumes input of Japanese in Roman characters, and input of capital English letters is less frequent. The input of alphabetic capital letters is less efficient than the first embodiment, but can be input using the shift key (471) or the shift key (482) of FIG.

  The Shift key of the shift key (471) or the shift key (482) performs the same operation as the shift key (1691) or the shift key (1703) of the conventional keyboard of FIG. The shift key (1691) or the shift key (1703) is operated using a little finger.

  On the other hand, the left thumb shift key (475) or the right thumb shift key (477) is usually operated using the thumb. The little finger is weaker and easier to get tired than the thumb. Furthermore, the thumb shift is almost always performed at a fixed position, while the little finger is also used for the operation of other character keys.

    In the third embodiment, as the keyboard hardware, the keyboard hardware of FIG. 15 is used instead of the keyboard hardware of FIG.

  In the keyboard hardware of FIG. 15, the switching keys such as the switching number / key (116), switching character key (136), and switching function key (156) of FIG. 1, the shift key (171), and the shift key (182) are displayed. The Shift key has been reduced.

  These functions are also provided in Example 1 or Example 2 in relation to compatibility and affinity with the conventional keyboard of FIG. 16, and in Example 3, these functions are deleted. In order to reduce the number of keys, an equivalent function is realized by the operation of the left thumb shift key (1575) and the right thumb shift key (1576) in FIG.

  That is, the switching function of the switching number / key (116), switching character key (136), and switching function key (156) in FIG. 1 is shifted by the left thumb shift key (1575) and the right thumb shift key (1576) in FIG. The shift operation of the Shift key (171) and the Shift key (182) Shift key can be replaced by the shift operation of the left thumb shift key (1575) or the right thumb shift key (1576) by changing the state.

However, there is a difference in operability different from that of a conventional keyboard, such as a shift operation that is mainly operated with the little finger needs to be operated mainly with the thumb.
In the third embodiment, the reduction in the number of keys is more important than the difference in operability.

  In the above embodiment, the 48-key keyboard shown in FIG. 1 or the 44-key keyboard shown in FIG. 15 is used as the keyboard hardware. A keyboard can be used.

  In this case, the left and right thumb shift keys may not be used for inputting numbers and symbols, and may be used when convenient for touch typing. In general, touch typing of numbers and symbols with 109 keys is not easy compared to touch typing with 48 keys.

In the 48-key keyboard shown in FIG. 1, the keys are arranged in a regular grid pattern. On the other hand, in a normal 109-key keyboard, the keys are arranged in a staggered pattern. The key map is displayed in a regular grid pattern, and it is desirable that the keys be arranged in a regular grid pattern for operation while viewing the key map.

The definition of the left and right α, β, and γ states in the embodiment can be changed as follows.
A state in which the left thumb shift key is pressed is defined as a left shift α state. A state where the left thumb shift key is pressed and the left thumb shift key is pressed is defined as a left shift β state. A state where the left thumb shift key is continuously pressed twice and the left thumb shift key is pressed is defined as a left shift γ state.

  When the left thumb shift key is pressed and another key is pressed instead of pressing the left thumb shift key, the key input in the unshifted state is performed, and the previous left thumb shift key is invalidated. As described above, even if the definition of the multi-level thumb shift is changed, the overall function and operation are not significantly affected.

  In the embodiment, a keyboard connected to a personal computer with a standard interface has been described. However, the connected device may be a general information processing device such as a mobile device instead of a personal computer.

  In addition, the keyboard and the information processing device are not externally connected, and the keyboard and the information processing device may be integrally configured, such as an electronic dictionary.

  The electronic device provided with the character input keyboard of the present invention is useful as a device for inputting character data such as characters and symbols into a digital information device such as a personal computer, a portable information terminal, or an electronic dictionary.
