`[0009]
`In this invention, a character list display means for displaying a
`plurality of character information comprising characters applicable
`to a specific character type is displayed on a display means. A user
`instructs any character of the character list display means by an
`instruction means. Then, a character type display means for
`displaying the character applicable to at least one other character
`type applicable to the character instructed by the instruction means
`is displayed on a display means. A user instructs a desired
`character of the character type display means by the instruction
`means and detaches the instruction means. Thereby, the character
`information applicable to the character type of the character
`currently displayed at the detached position in the character type
`display means is displayed on the display means.
`[0010]
`[Mode for Carrying Out the Invention]
`Preferred embodiments of this invention will be described in detail
`below based on the accompanying drawings.
`The embodiments described below are the preferred examples of
`this invention with various technically preferred limitations;
`however, the scope of this invention is not limited to these
`embodiments as long as there is a specific statement to that effect.
`
`

`
`
`
`
`the like, are used to manage business and individual information
`and to further use this information. For example, when the above-
`mentioned information equipment is used as an example, this
`information equipment is operated by a user using a predetermined
`pointing device, for example, to operate a screen displayed by a
`predetermined software installed in a display unit provided to the
`information equipment. Such screens employ a user interface
`usually called a GUI (Graphical User Interface) to allow easy
`operation by a user. There has been much competition to improve
`performance and to make such information equipment smaller and
`smaller to allow easy portability by a user.
`[0003] Thus, the smaller the information equipment is, the smaller
`the display surface area of a display unit naturally becomes.
`Therefore, the object to be displayed on a display unit by a
`predetermined
`software becomes
`small, deteriorating
`the
`operability of GUI, which is a drawback. For example, drawbacks
`in a software keyboard which is an object to be displayed on a
`display unit as an example will specifically be described below. A
`“software keyboard” refers to the software that has a keyboard
`function that can input a character into the information equipment.
`[0004]
`[Problem to be Solved by the Invention] FIG. 25-FIG. 27 are
`drawings
`respectively
`illustrating a conventional
`software
`keyboard in the display state displayed on a display unit. In FIG.
`25, a software keyboard 106 has a full-width hiragana display area
`107, a full-width katakana display area 108, and a half-width
`katakana display area 109, for example. Therefore, when the
`software keyboard 106 is displayed on a display unit having a
`small display area, each character becomes small and hard to see,
`so a large display area according to the character type such as
`hiragana and katakana, and full width and half width, becomes
`necessary.
`[0005] In FIGS. 26(A)-(C), the software keyboard 106 is devised
`so that the character information of a plurality of character types is
`displayed on one screen in order to eliminate the drawback shown
`in FIG. 25. Therefore, the software keyboard 106 has a full-width
`hiragana button 106a, a full-width katakana button 106b, and a
`half-width katakana button 106c, for example, in addition to the
`display area for displaying the character information. With the
`software keyboard 106 shown in FIGS. 26 (A)-(C), a user needs to
`operate each button to display the character information by
`distinguishing the full-width hiragana, the full-width katakana, and
`the half-width katakana as a character type.
`[0006] In FIG. 27, the software keyboard 106 is provided with
`input sections (a voiced sound key 106e and a p‐sound
`key 106f, or a small character button 106b [sic: d] shown in FIG.
`27) in order to reduce the size of display area of the character
`information as shown in FIGS. 26 (A)-(C); these input sections are
`used for adding a voiced sound mark or a P-sound consonant mark,
`or for converting an upper case display to a lower case display or
`vice versa in the software keyboard capable of inputting Roman
`alphabets. In such a software keyboard 106, a user must switch to
`the character information according to the desired character type
`every time.
`[0007] The objective of the present invention is to eliminate the
`problems described above and to provide a character input device
`that can perform a character input simply and correctly and has a
`small display area of a character list display means, as well as to
`provide a character input method, and an information recording
`medium for storing a program having a character input function.

`
`[0018] FIG. 3 is a functional block diagram illustrating the
`functional example of the software keyboard of FIG. 1. The
`software keyboard 6 has a drag menu information table 17
`(character information storing means) and a character information
`display means 19. A “drag” in the description below refers to a
`state when a user contacts the tip 3a of the pointing device 3 to the
`software keyboard 6, or the like, displayed on the display unit 5,
`for example, and slides the top of the surface of the tablet 7.
`[0019] The drag menu information table 17 stores the characters
`for each character type, for example. The information (hereinafter
`will be called drag menu information) of the drag menu
`information table 17 for displaying the drag menu 18 when the
`drag menu 18 (character type display means) shown in FIG. 8 is
`displayed is read by the character information display means 19
`that will be described below. The form shown in FIG. 4 is an
`example of the drag menu information. That is, characters for each
`character type applicable to the key pressed in the software
`keyboard 6 when the tablet 7 is touched (hereinafter will be
`referred to the task when the software keyboard 6 is instructed with
`the pointing device 3) are stored.
`[0020] The character information display means 19 is a software
`that uses the storage unit 11 as a workspace by the control of the
`control unit 9 shown in FIG. 2, for example. The character
`information display means 19 searches the drag menu information
`table 17 when the software keyboard 6 is displayed on the display
`unit 5 shown in FIG. 1, displaying the character information for
`each character type as shown in FIGS. 6 (A)-(C), for example. The
`character information display means 19 searches the drag menu
`information table 17 and displays the drag menu information when
`the drag menu 18 shown in FIG. 8, for example, is displayed after a
`user touches the tablet 7 (this position is called the first position A),
`when the software keyboard 6 is displayed on the display unit 5
`(FIG. 7).
`[0021] The character information display means 19 displays a
`screen shown in FIG. 8 as the drag menu 18 on the display unit 5.
`This drag menu 18 searches the drag menu information table 17
`shown in FIG. 4 based on the character touched with the pointing
`device 3 and displays characters applicable to all character types.
`The drag menu 18 preferably searches the drag menu information
`table 17 of FIG. 4 to be classified into each character type
`(selection options of the drag menu shown in FIG. 4) by some
`character units as shown in FIG. 8. This is done so that a user can
`easily recognize the character for each character type when using
`the software keyboard 6.

`
`
`
`
`[0011] In the following descriptions, a “character type” refers to
`the combination of a straight syllable, a voiced sound, a p‐sound
`in the kana syllabary, a contracted sound, a geminate consonant, a
`conventional special character, a hiragana, katakana, the full width
`and half width thereof in the case of Japanese character input, and
`refers to upper and lower cases in the case of other language input
`(for example, English). The “character information” refers to a
`plurality of characters for each character type. It is described below
`that a keyboard is displayed by a software in order to enter
`characters in an information equipment; however, a “key” shall
`refer to a key displayed by a software applicable to the key of
`typical keyboard key (softkey).
`[0012]
