Depending on the tilt direction, the map display position can be changed, and various setting items and switches can be selected. In addition to tilting the joystick 22, the joystick 22 can be pushed as shown in FIG. By pressing the joystick 22, the selection can be confirmed or the contents of the selected switch can be executed.

  Next, the 50 sound input method in the navigation device 1 according to the embodiment of the present invention will be described with reference to FIGS. It is assumed that the occupant intends to set the destination of the search route with 50 sound inputs. The first character of the destination name that the occupant intends to set is "Nu".

  First, the occupant selects a “set destination” menu 31 which is a menu for setting a destination for route search from the menus 31 to 35 displayed on the display monitor 16 together with the map screen 36. The selection is performed by tilting the joystick 22 of the remote controller 20. When the “Destination setting” menu 31 is selected and the joystick 22 is pressed to confirm, pull-down menus 31a to 31f relating to destination setting means are displayed. Since the occupant inputs the name with 50 sound inputs and sets the destination of the search route, tilt the joystick 22 of the remote controller 20 and select “From Name” 31b. Then, the joystick 22 is pushed to confirm.

  When the occupant presses the joystick 22 to confirm the selection, the syllabary character input board 40 is displayed on the display monitor 16 as shown in FIG. The 50-sound character input board 40 is a screen for inputting 50 sounds, and includes an input character display area 41 and a character input area 42. In the input character display area 41, input characters are displayed. In the character input area 42, characters 42 a to 42 k (hereinafter referred to as row selection characters) of each line of 50 sounds are displayed in a horizontal row. The occupant selects a line from the line selection characters 42a to 42k, and then selects a character to be input from the characters in the selected line. The occupant can change the line selection characters 42a to 42k selected by tilting the joystick 22 rightward or leftward to the adjacent line selection characters 42a to 42k. If the joystick 22 is continuously tilted rightward or leftward, the selected line selection characters 42a to 42k are sequentially changed to characters positioned in the rightward or leftward direction.

  When the syllabary character input boat 40 is displayed, the line selection character 42a “A” is selected first. The selected line selection character 42a is displayed in a color different from that of the other line selection characters 42b to 42k. Characters related to that line other than the line selection character 42a are displayed on the left and right sides of the selected line selection character 42a. When the line selection character 42a “A” is selected, the character “421” “421” is displayed on the upper left side of “A”, and the character “422” is displayed on the upper right side of “A”. The character “423” is displayed at the lower left of “A”, and the character “424” is displayed at the lower right of “A”. When the other line selection characters 42b to 42k are also selected, the character in the line corresponding to the line selection characters 42b to 42k is located at the upper right position at the upper left position of the line selection characters 42b to 42k. The characters in the row corresponding to the line selection characters 42b to 42k are in the lower left position, the characters in the row corresponding to the line selection characters 42b to 42k are in the lower left position, and the line selection characters 42b to 42b in the lower right position. The characters in the row of the line covering 42k are displayed.

  The occupant tilts the joystick 22 to the right to change the line selection characters 42a to 42k to be selected in order to select the row selection character 42e “na” in the row including the characters “Nu”. When the occupant selects the line selection character 42e “na”, the remaining characters “ni”, “nu”, “ne”, “no” characters 421e to 424e (hereinafter referred to as “n”) on the line selection character 42e. , The dan, dan, dan and dan characters relating to the line selection character are referred to as derived characters). Since the character “n” is in the row of the character 421e, it is displayed at an upper left position of the character “e” 42e, and the character “n” is in the row of the character 422e. The character 42e is displayed at a position on the upper right side of the character 42e, and is a character in the row of the character "423e". Therefore, the character 42e is displayed at a position on the lower right of the character 42e, and the character "424" Since the character is in the row, it is displayed at a position diagonally to the lower right of the character 42e of “NA”.

  Next, the character 422e of “Nu” is selected from the characters of the “N” line, and each character of the N line is selected as follows. Of the characters in the “NA” line, the input of the “NA” character 42 e is confirmed by pressing the joystick 22 as it is, and the character “NA” can be input to the navigation device 1. The input of the character “421” of “Ni” can be confirmed by pressing the joystick 22 after the joystick 22 is tilted obliquely upward to the left, and the character “Ni” can be input to the navigation device 1. The character “422” can be input to the navigation device 1 by pressing the joystick 22 after the joystick 22 is tilted obliquely upward to the right and then pressing the joystick 22. The input of the “Ne” character 423e can be confirmed by pressing the joystick 22 after tilting the joystick 22 diagonally to the left and inputting the “Ne” character into the navigation device 1. The character 424e of “NO” can be input by pressing the joystick 22 after the joystick 22 is tilted diagonally downward to the right, and the character “NO” can be input to the navigation device 1. With respect to the other line selection characters 42a to 42k, a desired character can be input by the same operation. As shown in FIG. 6, the occupant selects and inputs the character 422e of “Nu”. The character “422e” 422e is displayed in the input character display area 41. The name of the destination can be input by the occupant repeating the above operation. When the input is completed, an end button (not shown) provided on the remote controller 20 is pressed.

  Next, the 50 sound input process in the navigation device 1 according to the embodiment of the present invention will be described with reference to the flowcharts of FIGS. 7 and 8 is executed by the control circuit 11 executing a program that starts when a menu that requires a name or the like to be input with 50 sounds is selected.

  In the explanation of the flowchart below, “characters in the right direction”, “characters in the left direction”, “characters in the upper left direction”, “characters in the lower left direction”, and “right diagonal” The terms “upper-position characters” and “right diagonally lower-position characters” are used but are defined as follows. The “right position character” and the “left position character” of the line selection characters 42a to 42k are the line selection characters 42a to 42k that are located on the right side and on the left side. For example, the “character in the right direction” of the character 42 e “NA” in FIG. 5 is the character 42 f in “HA”, and the “character in the left position” is the character 42 d in “TA”. There are other characters in the right or left position of the derived character, but they are not in the next position, so the characters “right position” and “left position” of the derived character do not exist And Therefore, the character 422e “N” exists in the right direction of the character 421e “NI” in FIG. 5 but does not correspond to the character “position in the right direction”, and the character 424e “NO” in the left direction. It is assumed that the character “423e” “423” exists but does not correspond to the “character at the left position”.

  “Character at position left diagonally upward”, “Character at position diagonally down left”, “Character at position diagonally upward right”, and “Character at position diagonally down right” are line selection characters 42a-42. 42k and the character related to the positional relationship between the line selection characters 42a to 42k, and between the line selection characters 42a to 42k and the derived characters not related to the line selection characters 42a to 42k, Even in such a positional relationship, “characters in the position diagonally up to the left”, “characters in the diagonally down left direction”, “characters in the diagonally up right direction” and “characters in the diagonally down right direction” “Position character” shall not be applicable. For example, the “character at the position in the upper left direction” of the character 424e of “NO” in FIG. 5 becomes the character 42e of “NA”. However, even if the “ma” character 42g is positioned in the diagonally upper right direction of the “no” character 424e, the “ma” character 42g is positioned at the “right diagonally upward” position of the “no” character 424e. Does not fall under "character".

In step S <b> 701, the syllabary character input board 40 is displayed on the display monitor 16. In step S702, the line selection character 42a “A” is selected. In step S703, it is determined whether or not the joystick 22 has been pressed. If the button has been pressed, an affirmative determination is made in step S703 and the process proceeds to step S704. If not pressed, a negative determination is made in step S703, and the process proceeds to step S707. In step S704, the selected character is input. In step S <b> 705, it is determined whether the 50-sound input process has been completed with an end button (not shown) provided on the remote controller 20. If completed, an affirmative determination is made in step S705, and the 50-sound input process ends. If not completed, the process proceeds to step S706. In step S706, the selected character is changed to line selection characters 42a to 42k related to the input character. For example, when the character 422e of “Nu” is input, the character 42e of “NA” is selected. Then, the process returns to step S703.

  In step S707, it is determined whether the joystick 22 is tilted rightward. If it is tilted to the right, an affirmative determination is made in step S707 and the process proceeds to step S708. If the joystick 22 is not tilted to the right, a negative determination is made in step S707 and the process proceeds to step S710. In step S708, it is determined whether or not the “character at the right position” of the selected character exists. For example, if the “a” character 42a shown in FIG. 4 is selected, the “42” character 42b exists at the right position of the “a” character 42a, so that an affirmative determination is made in step S708. . On the other hand, if the “u” character 422a shown in FIG. 4 is selected, there is no “right-positioned character”, so a negative determination is made in step S708. If there is a “character at the right position” of the selected character, an affirmative decision is made in step S708 and the operation proceeds to step S709. If it does not exist, a negative determination is made in step S708, and the process returns to step S703. In step S709, the selected character is changed to "a character at a right position". Then, the process returns to step S703.

  In step S710, it is determined whether the joystick 22 is tilted leftward. If it is tilted leftward, an affirmative determination is made in step S710 and the process proceeds to step S711. If the joystick 22 is not tilted leftward, a negative determination is made in step S710 and the process proceeds to step S801. In step S711, it is determined whether the “character at the left position” of the selected character exists. For example, when the “NA” character 42e displayed in FIG. 5 is selected, the “NA” character 42d exists at the left position of the “NA” character 42e. Determined. On the other hand, when the “Nu” character 422e displayed in FIG. 5 is selected, since “the character at the left position” does not exist, a negative determination is made in Step S711. If there is a “character at the left position” of the selected character, an affirmative determination is made in step S711 and the process proceeds to step S712. If it does not exist, a negative determination is made in step S711, and the process returns to step S703. In step S712, the selected character is changed to “a character at a left position”. Then, the process returns to step S703.

  In step S801, it is determined whether the joystick 22 has been tilted obliquely upward to the left. If it is tilted leftward and upward, an affirmative determination is made in step S801 and the process proceeds to step S802. If the joystick 22 is not tilted obliquely upward to the left, a negative determination is made in step S801, and the process proceeds to step S804. In step S <b> 802, it is determined whether there is a “character at a position in the upper left direction” of the selected character. For example, when the “NA” character 42e displayed in FIG. 5 is selected, the “NI” character 421e exists at a position in the diagonally upper left direction of the “NA” character 42e. Is affirmed. On the other hand, when the character “422e” displayed in FIG. 5 is selected, there is no “character at a position in the diagonally upper left direction”, so a negative determination is made in step S802. If there is a “character at a position in the upper left direction” of the selected character, an affirmative determination is made in step S802 and the process proceeds to step S803. If it does not exist, a negative determination is made in step S802, and the process returns to step S703. In step S803, the selected character is changed to “a character at a position in the upper left direction”. Then, the process returns to step S703.

  In step S804, it is determined whether the joystick 22 has been tilted obliquely downward to the left. If it is tilted to the left diagonally downward, step S804 is affirmed and the process proceeds to step S805. If the joystick 22 is not tilted obliquely upward to the left, a negative determination is made in step S804, and the process proceeds to step S807. In step S805, it is determined whether or not the “character at a position in the diagonally lower left direction” of the selected character exists. If there is a “character at a position diagonally downward to the left” of the selected character, an affirmative determination is made in step S805 and the process proceeds to step S806. If it does not exist, a negative determination is made in step S805, and the process returns to step S703. In step S806, the selected character is changed to “a character at a position in the diagonally downward left direction”. Then, the process returns to step S703.

  In step S807, it is determined whether the joystick 22 is tilted obliquely upward to the right. If it is tilted to the right and upward, an affirmative determination is made in step S807 and the process proceeds to step S808. If the joystick 22 is not tilted leftward and upward, a negative determination is made in step S807 and the process proceeds to step S810. In step S808, it is determined whether there is a “character at a position diagonally right upward” of the selected character. If there is a “character at a position obliquely upward to the right” of the selected character, an affirmative determination is made in step S808 and the process proceeds to step S809. If it does not exist, a negative determination is made in step S808, and the process returns to step S703. In step S809, the selected character is changed to “a character at a position diagonally right upward”. Then, the process returns to step S703.

  In step S810, it is determined whether or not the joystick 22 has been tilted obliquely downward to the right. If it has been tilted to the right diagonally downward, step S810 is positively determined, and processing proceeds to step S811. If the joystick 22 is not tilted in the diagonally downward left direction, a negative determination is made in step S810, and the process proceeds to step S703. In step S811, it is determined whether there is a “character at an obliquely lower right position” of the selected character. If the selected character “character at a position diagonally downward to the right” exists, an affirmative determination is made in step S811 and the process proceeds to step S812. If it does not exist, a negative determination is made in step S811, and the process returns to step S703. In step S809, the selected character is changed to “a character at an obliquely lower right position”. Then, the process returns to step S703.

The navigation device 1 according to the above embodiment has the following operational effects.
(1) When the occupant tilts one of the eight directions of the vertical, horizontal and diagonal directions, the horizontal two directions of the joystick 22 or one of the two vertical directions can play 50 sounds. The character of the second row can be selected, and when the occupant tilts one of the four oblique directions of the joystick 22, the same character as the selected second row can be selected. One of the characters in the row, row, row, and row can be selected, so that 50 sounds can be input with a simple operation.
(2) Since the tilt direction of the joystick 22 when selecting the dan, dan, dan and dan characters on the same line as the dan character is common to each dan character of 50 sounds, It is not necessary to remember the tilting direction of the joystick 22 when selecting each character, and the input of characters becomes faster.
(3) On the syllabary character input board 40, there are derived characters in the diagonal direction of the line selection characters 42a to 42k which are the first characters of each line of 50 syllabary lines arranged in a horizontal row and one line selection character 42a to 42k. It is displayed on the display monitor 16. Therefore, when selecting a character to be input, the joystick 22 may be tilted in the direction of the character to be input. Therefore, it is not necessary to remember in advance the rotation position or tilt position of the joystick 22 corresponding to each line or word, and 50 sounds can be input with a simple operation.
(4) In the character input area 42 of the syllabary character input board 40, only the derived characters of the line selection characters 42a to 42k and the one line selection character 42a to 42k, which are the first characters of each line of the syllabary, are displayed. Makes it easier to look for to select a character. Moreover, since there are few characters displayed, a character can be enlarged and it can be made easy to see a character.
(5) If the operation of tilting the joystick 22 in the left-right direction is continued and finally the joystick 22 is tilted once in the oblique direction, a character to be input can be selected. Therefore, a desired character can be input by a simple operation.

The above embodiment can be modified as follows.
(1) Although the character input area 42 is displayed on the 50 sound input board 40 in the above embodiment, the selected line selection characters 42b to 42k are displayed in the input character display area 41, and the character input area 42 is displayed. It does not have to be displayed. This is because if the selected line selection characters 42b to 42k are displayed in the input character display area 41, a desired character can be selected by operating the joystick 22 even if the character input area 42 is not displayed. . For example, as shown in FIG. 9, it is assumed that the character 91 “ka” of the line selection character 42 b is displayed in the input character display area 41 and the occupant intends to input the character “ni”. Even if the character input area 42 is not displayed, the occupant tilts the joystick 22 to the right and displays the character “NA”, which is the line selection character 42 e of the character “NI”, in the input character display area 41. be able to. Even if the character input area 42 is not displayed, since the character “ni” is a “yes” level character, the character “ni” can be selected by tilting the joystick 22 diagonally left upward. it can. Since the character input area 42 is not displayed, the display of the syllabary character input board 40 can be reduced, and the menus 31 to 35, 31a, 31d to 31f are not hidden by the syllabary character input board 40. On the other hand, it is possible to easily grasp whether or not 50 characters are input.
(2) Although all line selection characters 42a to 42k of 50 sounds are displayed on the 50 sound character input board 40, some line selection characters 42a to 42k may be displayed.
