Description

  The present invention relates to an electronic device and a character input method for the electronic device.

As is well known, in a portable terminal such as a mobile phone or a PHS terminal, a character is input by moving the cursor by operating the up / down / left / right keys when inputting a character such as an email or a text memo.
For example, Non-Patent Document 1 (a pdf file of an instruction manual of a mobile phone (model number: W51K) manufactured by Kyocera Corporation) discloses key operations on an input screen of the mobile phone. This cellular phone moves the cursor upward, downward, leftward, or rightward by operating the up / down / left / right keys after character confirmation on the character input screen.
Internet <URL: http: //www.au.kddi.com/torisetsu/pdf/w51k/w51k_torisetsu.pdf>, page 46

By the way, the above conventional technique is complicated because the amount of movement of the cursor depends on the number of times the up / down / left / right key is pressed. For example, when the cursor is moved up five lines from the current position, the user must press the upper side of the up / down / left / right key five times. When the cursor is moved to a different column on the fifth row, it is necessary to change the column of the cursor moved to the fifth row by further pressing the right or left side of the up / down / left / right keys.
Therefore, the above-described prior art has a complicated cursor movement operation, and in particular, the movement operation when moving the cursor significantly is complicated and unusable.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide an electronic device and a character input method for the electronic device in which a cursor movement operation is easy.

In order to achieve the above object, according to the present invention, as a first solving means related to an electronic device, an electronic device that displays a document composed of a plurality of characters on a display unit together with a cursor, the desired position in the document is indicated. and one of the operation keys that accept an operation instruction regarding movement of the operation instruction and the cursor designating a reference position, respectively, and a storage unit for storing the reference position, the reference position for the specified, based on an operation instruction for the one operation key The reference position is stored in the storage unit, and when the one operation key receives an operation instruction related to the movement of the cursor, the display unit displays a document in which the cursor is moved to the reference position stored in the storage unit in advance. And means for including a control unit.

In the present invention, as a second solving means relating to the electronic device, in the first solving means, in the case where a plurality of reference positions are stored in the storage unit, the one operation key is an operation instruction related to cursor movement. The control unit employs means for moving the cursor to a reference position closest to the cursor position.

In the present invention, as the third solving means relating to the electronic apparatus, in the first or second solving means, when the one operation key receives an operation instruction related to designation of a reference position, the control unit A means for displaying a predetermined mark on is adopted.

In the present invention, as a means for solving the character input method, a character input method in an electronic apparatus having one operation key, the step of setting a reference position at a position designated based on an operation instruction for the one operation key And a step of moving a cursor to a reference position based on an operation instruction for the one operation key.

  According to the present invention, based on the pressing time of the cursor function key or the number of times of continuous pressing, the control unit stores a desired position in the designated document as a reference position in the storage unit and is stored in advance in the storage unit. Since the document with the cursor moved to the reference position is displayed on the display unit, the cursor in the document can be moved by an easy operation without performing complicated up / down / left / right key operations.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present embodiment relates to a PHS (Personal Handy-phone System) terminal which is one of electronic devices.

First, the external configuration of the PHS terminal A in the present embodiment will be described with reference to FIG.
As shown in FIG. 1, the PHS terminal A is of a folding type in which a display-side main body 1 and an operation-side main body 2 are connected by a hinge structure 3. The display-side main body 1 includes a display-side housing 4 and a display unit 5 provided on one surface of the display-side housing 4. Is formed. On the other hand, the operation-side main body 2 includes an operation-side housing 7 and an operation unit 8 provided on one surface of the operation-side housing 7. A talk 9 is formed.

  Next, with reference to the functional block diagram shown in FIG. 2, the functional configuration of the main part of the PHS terminal A will be described. In FIG. 2, the same components as those shown in FIG. 1 are denoted by the same reference numerals.

  The PHS terminal A includes a display unit 5, an operation unit 8, a communication unit 10, a storage unit 11, and a control unit 12, as shown in FIG. The display unit 5 is, for example, a liquid crystal display or an organic EL (Electronic Luminescent) display, and displays various screens including images and characters based on a control signal input from the control unit 12. One of the screens displayed on the display unit 5 is a character input screen for inputting characters such as e-mails and text memos.

  The operation unit 8 includes a power key, a numeric keypad, and various function keys. The operation unit 8 receives various operation instructions from the user and outputs them to the control unit 12. The operation unit 8 includes a cursor function key 8a as a function key. The cursor function key 8a designates a desired position on the character input screen as a reference position and sets a predetermined mark at the reference position. This is for receiving a position designation instruction, a cursor movement instruction for moving the cursor on the character input screen, and a reference position release instruction for canceling the designation of the reference position.

  The long press of the cursor function key 8a when the cursor is not at the same position as the reference position is used as a reference position designation instruction, and the long press of the cursor function key 8a when the cursor is at the same position as the reference position is a reference position release. Each control unit 12 is recognized as an instruction. One click of the cursor function key 8a is recognized by the control unit 12 as a sentence end cursor movement instruction, and double click is recognized as a sentence start cursor movement instruction.

  Note that the sentence head direction indicates the direction toward the first character of the sentence head on the character input screen, and the sentence end direction indicates the direction toward the last character at the end of the sentence on the character input screen.

The communication unit 10 transmits and receives various signals such as audio signals, control signals, and data signals with a base station (not shown) under the control of the control unit 12.
The storage unit 11 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores a predetermined control program executed by the control unit 12, and the RAM is a work area when the control unit 12 executes the control program, and stores the reference position under the control of the control unit 12. .
The control unit 12 controls the overall operation of the PHS terminal A based on a predetermined control program stored in advance in the storage unit 11, various operation instructions received by the operation unit 8, and various signals input from the communication unit 10. And control.

  Next, the operation of the main part of the PHS terminal A configured as described above will be described in detail with reference to the flowchart shown in FIG. 3 and the schematic diagram of the character input screen shown in FIG. FIG. 3 shows a character input control process executed by the control unit 12 based on a control program or the like. FIGS. 4A to 4G show a character input operation by operating the cursor function key 8a or a character input operation. It shows that the input screen changes sequentially.

As is well known, when inputting characters such as mails and text memos in a PHS terminal, the user moves a cursor on the character input screen by operating a predetermined operation key, and further operates a predetermined operation key related to the input character. Enter the character at the cursor position.
On the other hand, in the PHS terminal A, the user performs a reference position designation instruction, a reference position release instruction, or a cursor movement instruction by operating the cursor function key 8a on the character input screen displayed on the display unit 5. By operating an operation key other than the cursor function key 8a in the operation unit 8, a new character is input at the cursor position.

  In the character input control process in which the character input screen is displayed on the display unit 5, the control unit 12 determines whether or not the cursor function key 8a is first pressed (step S1), and the cursor function key 8a is pressed. If it is determined that the cursor function key 8a is not pressed (NO), the process waits until the cursor function key 8a is pressed. If it is determined that the cursor function key 8a is pressed (YES), the pressing time of the cursor function key 8a is counted. (Step S2) It is determined whether or not the pressing of the cursor function key 8a is a long press based on the measured pressing time of the cursor function key 8a (Step S3).

  If the control unit 12 determines that the long press is made in step S3 (YES), the cursor is at the same position as the reference position by comparing the cursor position with the reference position stored in the storage unit 11. If it is determined in step S4 that it is not a long press (NO), that is, if it is determined that it is a short press, the cursor position and the reference position stored in the storage unit 11 are compared. Thus, it is determined whether or not the reference position exists at a position different from the cursor position. (Step S9).

  If it is determined in step S4 that the cursor is not at the same position as the reference position (NO), the control unit 12 recognizes the reference position designation instruction and stores the cursor position as the reference position in the storage unit 11 (step S5). Then, a mark is displayed on the display unit 5 at the reference position (step S6). If the control unit 12 determines in step S4 that the cursor is at the same position as the reference position (YES), the control unit 12 recognizes the reference position release instruction and deletes the reference position at the same position as the cursor from the storage unit 11. (Step S7), the mark displayed at the reference position is erased on the display unit 5 (Step S8).

The display of the mark at the reference position in step S6 described above will be described in detail with reference to FIGS. 4 (a) and 4 (b).
FIG. 4A shows a character input screen before the reference position is designated. The position of the cursor is designated as a reference position by long pressing the cursor function key 8a while the character input screen of FIG. 4A is displayed, and the character input screen is designated as shown in FIG. 4B. A mark is displayed at the reference position. This mark is indicated by making the background color of the reference position different from the normal white background color of the character input screen.
Also, the transition of the character input screen from (b) to (c) of FIG. 4 is similar to the transition of the character input screen of (a) to (b) of FIG. The position is designated as the reference position, and a mark is displayed at the reference position.

FIG. 5 is a schematic diagram of a reference position table stored in the storage unit 11.
In the reference position table, a reference position is recorded for each reference position ID. The reference position ID is an identification number for identifying each reference position, and is assigned in order from the reference position in the sentence head direction. The relative position of each reference position is stored in the reference position of the reference position table. The relative position of each reference position is based on the RAM address where the character input by the operation of the operation unit 8 is stored, and the interval of the RAM address where the character at the same position as each reference position is stored. And the interval is indicated by the data size, that is, bytes.

  For example, 22 bytes are recorded as the reference position at the reference position 3 in the reference position table of FIG. 5, which indicates that the reference positions of the reference position 3 and the reference position 2 are separated by 22 bytes. . In the case of the reference position 1, 4 bytes are recorded as the reference position. This is because the reference position of the reference position 1 is at a position 4 bytes away from the RAM address where the first input character is stored. Indicates that there is.

  When it is determined in step S9 that the reference position does not exist at a position different from the cursor position (NO), the control unit 12 executes step S4, and in step S9, the reference position is at a position different from the cursor position. If it is determined that it exists (YES), it is determined whether the cursor is at the same position as the reference position by comparing the position of the cursor with the reference position stored in the storage unit 11 (step S10).

  When the control unit 12 determines in step S10 that the cursor is at the same position as the reference position (YES), the cursor function key 8a key is used to determine whether the short press of the cursor function key 8a is one-click or double-click. Is timed from when the button is released to the next time it is pressed (step S13). If it is determined in step S10 that the cursor is not at the same position as the reference position (NO), the cursor position is set as the reference position. It memorize | stores in the memory | storage part 11 (step S11), a mark is displayed on the display part 5 at the said reference position (step S12), and step S13 is performed.

  The control unit 12 determines whether or not the pressing of the cursor function key 8a is a double click based on the time measured in step S13 (step S14). The cursor is moved to the reference position closest to the beginning of the sentence on the display unit 5 based on the reference position closest to the beginning of the sentence from the cursor stored in the storage unit 11 (step S15). When it is determined that it is not a click (NO), that is, when it is determined that it is a one-click, it is recognized as a cursor movement instruction in the sentence end direction, and based on the reference position closest to the sentence end direction from the cursor stored in the storage unit 11, The cursor is moved to the reference position closest to the end of the sentence on the display unit 5 (step S16).

The cursor movement in the sentence head direction in step S15 described above will be described in detail with reference to the character input screens of FIGS. 4 (c) and 4 (d).
FIG. 4C shows a character input screen in which reference positions exist at two locations and the cursor is positioned at the end of the sentence. In the state where the character input screen of FIG. 4C is displayed, by double clicking the cursor function key 8a, a mark indicating the reference position is displayed at the cursor position before the movement as shown in FIG. 4D. The cursor moves to the reference position closest to the beginning of the sentence.

The cursor movement toward the end of the sentence in step S16 will be described in detail with reference to the character input screens shown in FIGS.
FIG. 4E shows a character input screen having reference positions in the direction of the sentence head and the direction of the sentence end from the cursor position. In the state where the character input screen of FIG. 4E is displayed, the cursor moves to the reference position closest to the end of the sentence as shown in FIG. 4F by one click of the cursor function key 8a.
Also, the transition of the character input screen from (f) to (g) in FIG. 4 is similar to the transition of the character input screen from (e) to (f) in FIG. It is shown that the cursor moves to the reference position closest to.

  The movement amount of the cursor in the sentence head direction in step S15 and the movement amount of the cursor in the sentence end direction in step S16 are determined from the reference position stored in the storage unit 11 and the cursor position. The cursor position is managed by the control unit 12 as a RAM address where the character where the cursor is located is stored.

  Referring to FIG. 5, for example, when the cursor is positioned at the reference position 3 and the cursor movement instruction in the direction of the sentence head is given, the reference position 3 of the reference position table has 22 bytes as the reference position. Since it is recorded, it can be seen that the reference position of the reference position 2 as the cursor movement destination is located at a position separated by 22 bytes from the reference position 3 in the sentence head direction, and the cursor moves 22 bytes in the sentence head direction. When the cursor is positioned at reference position 3 and there is an end-of-sentence cursor movement instruction, when the cursor is positioned at reference position 3 and when there is an end-of-sentence cursor movement instruction, the reference position table is referenced. Since 15 bytes is recorded as a reference position at position 4, it can be seen that the reference position 4 to be moved is a position 15 bytes away from the reference position 3 in the sentence end direction, and the cursor moves 15 bytes in the sentence end direction.

  When the cursor is not at the same position as the reference position and there is an instruction to move the beginning of the cursor, each reference position is stored at the address of the RAM where the first character input by the operation of the operation unit 8 is stored. By adding the reference positions in the reference position table indicating the relative positions of the reference positions in the order of reference position ID numbers, the reference position closest to the sentence head direction is derived from the cursor position, and the cursor moves to the derived reference position. . When the cursor is not in the same position as the reference position and there is an instruction to move the end of the cursor, the reference position table is referenced at the RAM address where the first character input by the operation of the operation unit 8 is stored. By adding the positions in the order of reference position ID numbers, the reference position closest to the end of the sentence is derived from the cursor position, and the cursor moves to the derived reference position.

  When the character is input, the control unit 12 determines whether or not the character is input at the reference position by comparing the position where the character is input and the reference position stored in the storage unit 11 (step S17). When it is determined in step S17 that a character has been input at the reference position (YES), the reference position where the character has been input is deleted from the storage unit 11 (step S18), and the input character is displayed on the display unit 5. At the same time, the mark at the reference position is erased (step S19). If it is determined in step S17 that no character is input at the reference position (NO), step S18 and step S19 are not executed.

The deletion of the reference position by the character input in step S18 described above will be described in detail with reference to the character input screens of FIGS. 4 (d) and 4 (e).
FIG. 4D shows a character input screen in which the cursor is positioned at the reference position. In the state where the character input screen of FIG. 4D is displayed, when a character is input at the reference position by operating the operation unit 8, the character is input as shown in FIG. The mark indicating the reference position at the selected position is deleted.

  As described above, according to the present embodiment, the position of the character input screen designated by the user is stored in the storage unit 11 as the reference position, and the storage unit 11 can be obtained by one-clicking or double-clicking the cursor function key 8a. Since the cursor can be moved based on the stored reference position, it is possible to move the cursor by an easy operation without performing complicated up / down / left / right key operations.

  Further, since the control unit 12 identifies each operation instruction of the reference position designation instruction, the reference position release instruction, and the cursor movement instruction by properly pressing the cursor function key 8a, one-click or double-click, the user can use the cursor function. The reference position can be designated, the reference position can be released, and the cursor can be moved only by operating the key 8a alone.

As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, For example, the following modifications can be considered.
(1) In the above embodiment, as the reference position of the reference position table, the relative position of each reference position is recorded for each reference position ID, but the present invention is not limited to this.
