The present invention relates to an audio information retrieval apparatus that can perform the above.

  In recent years, portable audio devices have been able to always carry and use devices that have recorded thousands of pieces of audio due to the increased capacity of data storage media, the ease of capturing audio content, and the increased processing speed. It has become. In addition, with the improvement of the functions of mobile phones, the functions provided by conventional portable audio devices are also provided. Moreover, not only listening to music, but also recording and carrying content with a focus on music with video and video such as movies.

  As a result, people who drive a car or passengers often bring these portable audio devices into the vehicle, while vehicles often have high-performance audio devices and are therefore usually listened to through earphones. It is often desired to listen to audio from a speaker in the vehicle using the audio device of the vehicle.

  In order to easily meet the demand of the audio device of the vehicle, the portable audio device is connected by wired or wireless, and the portable audio device that the connected user is used to in the operation unit and display unit of the audio device of the vehicle is used. It is desirable to be able to select and listen to arbitrary music by an operation similar to the operation of the apparatus.

JP 2007-323664 A JP 2006-323802 A

  When the portable audio device as described above is connected to the audio device of a vehicle and used to listen to an arbitrary song from among a large number of audio data existing on the data recording medium of the portable audio device, the artist A list of music can be acquired by specifying attributes such as album, track, and the like.

  Therefore, for example, when an artist name attribute is specified and a list is acquired, an artist name list in alphabetical order as shown in FIG. 11A is displayed on the display unit of the audio device of the vehicle. In the illustrated example, a list of artist names is displayed from the beginning in alphabetical order, and the cursor is moved to the artist “BBB” and displayed.

  The user looks at this display and performs operations such as a jog dial provided on the audio device of the vehicle, a jog stick, or a jog dial provided on the remote control (hereinafter collectively referred to as “JOG”). The artist name is displayed, the cursor is moved to match, and the selection is instructed. Thereafter, the user can listen to the desired song by displaying the album of the designated artist as necessary, further displaying the song name, and selecting an arbitrary song from among them.

  However, when there are thousands of songs on the portable audio device, the artist name becomes enormous, and in the jog operation as described above, the desired artist can be moved forward or backward. It will take a lot of time to reach. As a countermeasure, a recent portable audio device displays a slider bar such as 10 (%), 20, 30... 100% as shown in FIG. Some of them allow you to specify the ratio.

  Accordingly, when the first artist desired by the user starts with “M”, and it is considered that the artist is probably located at about one third of the whole, “30%” is selected. At that time, items of 30% or more and less than 40% of the total number of items are extracted, and the list of the extracted items is displayed from the first item.

  According to this list display, the user searches for a desired artist. For example, when the first letter of the artist name the user is trying to find is “M” as described above, the actual number is 45%. When present at the location, the user has performed a jog operation and found that it is not in the range of less than 40% and is likely to be in the range of “40%”, so it is indicated and similar Will be performed.

  In this way, a certain level of skill is required to specify the ratio of a desired item in the entire item based on intuition and to select a desired item based on the list of items in that range. Furthermore, when an extremely large number of items exist like an artist, there is a problem that it takes a lot of time and effort to search by this method even if “%” is specified as described above.

  As a countermeasure, it is easier to search by creating a tab list for each fixed character range.However, many portable audio devices need to rearrange the acquired list, and it takes a lot of time. It becomes a difficult search method and must be unpreferable as an actual product. Such a problem causes the same problem when various audio devices are connected to each other in addition to the case where the portable audio device and the vehicle audio device are connected.

  Therefore, according to the present invention, when an audio device is connected to another audio device and the music or the like is listened to using the data of the other audio device, for example, an artist is selected from among many audio data existing in the other audio device. It is a main object of the present invention to provide an audio information search apparatus that can easily and quickly search for a desired item such as a name.

In order to solve the above problems, an audio information search device according to the present invention includes an external audio device connection unit connected to an external audio device,
A tab selection unit for selecting an arbitrary tab among the tabs for dividing the item which is the audio data information of the external audio device into a plurality of tabs;

A display processing unit for displaying an item captured by the item capturing unit in the selected tab together with a tab including the item;
A display unit for displaying items and tabs processed by the display processing unit;
A search method instruction unit for a user to instruct a search method;
The tab selection unit sequentially selects a tab other than the tab displaying the current item according to the search method specified by the search method instruction unit,
In the selected tab item fetching unit, processing for fetching items belonging to the selected tab from an external audio device is detected, and in the selected tab item existence judgment unit, it is detected that there is an item to be fetched in the selected tab. Continue until
When there are items to be captured, the display processing unit displays a list of items captured by the item capturing unit in the selected tab together with the tab to which the item belongs,
When an instruction to search backwards in the search method instructing unit, wherein the tab selection section selects the reverse direction of the tab from the tab that indicates the current table,
In the tub item taking unit, the tabs that the selected in the selection tab in item exist not discriminating section, continues until it is determined that the item to take into the selected tab is present,
When it is determined that the item incorporated into the selected the tab is present, further for the previous tab, select the Madejun to determine an item in the selected tab in the item presence determination unit is present,
When it is determined that the item in the selection tab in item presence determination unit exists, that the tab with belonging of the item to find items forward, displays create a list in which the head of the first item retrieved It is characterized by.

  Since the present invention is configured as described above, by connecting the audio device and another audio device and listening to music using the data of the other audio device, by performing a search display using a tab, A desired item such as an artist name can be easily and quickly searched from among a large number of audio data existing in other audio devices.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an audio apparatus 1 embodying the present invention, in which an external audio apparatus 27 as a portable audio apparatus is connected to an external audio apparatus connection unit 2 so that data communication is possible. Various audio data recorded on the medium can be taken in and used, and the audio apparatus 1 outputs various instruction signals to the external audio apparatus 27, and the range of functions of the portable audio apparatus is provided. Various operations can be performed in this. Therefore, although the search function that can be performed by the audio apparatus 1 varies depending on the type and model of the external audio apparatus 27 connected to the audio apparatus 1, a general portable audio apparatus that is widely used nowadays. An example will be described.

  In the example of the audio apparatus shown in FIG. 1, the selection tab internal item capturing unit 3 is provided and displayed for use in the search of the present invention as described later, for example, “A to E”, “F to J”, “K”. For the tabs that are appropriately divided such as “˜O”, “P˜T”, “U˜Z”, “Other”, the user directly instructs to select or automatically searches, for example, “F˜J”. When a specific tab is selected and specified, items existing in the selected tab are fetched. The items acquired here are listed in an item list creation unit 6 described later, and are appropriately displayed in the search screen display processing unit 21.

  The selection tab item existence determination unit 4 determines whether or not an item exists in the tab selected as described above, and the tab selection unit 15 even when the item does not exist or even exists under a specific condition. To output an instruction signal for selecting the next tab. In this operation, when an item fetching process is performed in the selection tab item fetching unit 3, when it is detected that there is no item to be fetched, there is no item in the selection tab in the selection tab item existence judgment unit. Is determined. On the other hand, when the selection tab item fetching unit 3 detects that an item exists in the selection tab and the selection tab item presence / absence determination unit makes a determination to that effect, the tab selection unit 15 performs further determination. This is used as a signal indicating that there is no need to select a tab.

  In addition, when the selection tab item existence determination unit 4 determines that there is no item in the selected tab, the tab selection unit 15 can be instructed to automatically select the next tab. When the tab is selected by the user, an output indicating that no item exists in the selected tab is output, and a message to that effect is displayed if necessary.

  In the item existence tab storage unit 5, as described above, when the item existence determination unit 4 in the selected tab detects that an item exists in the selected tab, this data is used under a specific condition described later. Therefore, the tab stored in advance is output, the tab stored thereafter is output, the items included in the tab are fetched from the selected tab item fetching unit 3, and the search screen display processing unit 21 performs display processing. Do.

  In the display item list creation unit 6, when an appropriate amount of items included in the selected tab are fetched in the selection tab item fetching unit 3 as described above, a list is displayed for display on the display unit 26. And save it. Based on this list, the item display processing unit 24 of the search screen display processing unit 21 can cause the display unit 26 to sequentially display items belonging to the tab displayed by the tab display processing unit 22. The items to be listed here are displayed for the amount of items that can be captured when the normal function of the external audio device 27 can capture only a predetermined amount, and are listed for assisting search as necessary. To do.

  The user selection instruction input unit 7 in FIG. 1 is used by a user to input a selection instruction signal as appropriate in order to perform various processes related to the present invention in the audio apparatus. In the search function use instructing unit 8, when the user determines that the audio device 1 is to search for data of the currently connected external audio device, an input to that effect is made. This input can be performed by operating a function selection screen displayed on the display unit 26 or a specific function instruction switch provided on a remote controller or the like.

  In the tab selection instruction section 9 of the user selection instruction input section 7, when a tab is displayed on the tab display processing section 22 in the search screen display processing section 21 to be described later, an arbitrary tab is selected and designated. Do. Further, in the search method instruction unit 10, in order to select a desired item from the items listed in various aspects in the present invention, in the tab selection unit 15 having various tab selection methods, The user inputs to instruct whether to use the selection method.

  In the search method instruction unit 10, the tab selection unit 15 that actually performs a tab selection operation corresponds to various selection methods, and the forward direction instruction unit 11, the reverse direction instruction unit 12, and the tab direct instruction unit 13. In accordance with these instructions, any one of the forward direction tab selection 16, the backward direction tab selection 17, and the instruction tab selection 18 of the tab selection unit 15 is selected.

  In the beep sound output unit 14, for example, when an instruction is made to select a specific tab in the tab direct instruction unit 13 of the user selection instruction input unit 7, the tab is the same as the tab displaying the current item. When a selection instruction that should not be present is given, a beep sound is output to alert the user.

  In the tab selection unit 15, for example, when searching for an artist, selecting a desired artist from a large number of artists requires an extremely large amount of work as described in the prior art. Then, by using a data search function that is divided into a certain degree, which is provided in a general portable audio device, the alphabet is changed to, for example, “A to E”, “F to J”, “K to O”, “P to T”, “ A tab divided into an appropriate range such as “U to Z” is created, and a search within the range is performed. For this reason, the tab selection unit 15 automatically selects a tab for the tabs divided as described above, for a tab selected by the user using the tab selection instruction unit 9, or during a search operation as described later. The items included in the range of can be retrieved and search can be performed.

  The tab selection unit 15 shown in FIG. 1 performs an operation for selecting tabs in order when performing a search operation automatically, as will be described later. In the illustrated example, the selection is performed in the forward direction. Forward tab selection 16, backward tab selection 17 for selecting in the reverse direction, and instruction tab selection 18 for directing the user to select a tab. Which of these selection methods is adopted is determined depending on which instruction of the search method instruction unit 10 in the user selection instruction input unit 7 is performed as described above.

  Therefore, when the user presses the vehicle audio device itself or the right side of the remote control jog, the search is performed in the forward direction. When the user presses the left side, the search is performed in the reverse direction. The search is performed only for the tab instructed by moving to the tab. In addition, after performing such an instruction, when an actual search operation is performed, for example, when a specific tab is selected and an item within the range of the tab is searched, when there is no item, a tab in the same direction is automatically set. The operation of selecting can be performed.

  The search screen display processing unit 21 performs processing for displaying various information including items on the display unit 26 when performing various search operations as described above. The search screen display processing unit 21 includes a tab display processing unit 22 and displays preset tabs. It is not always necessary to display all the tabs displayed at this time, and only the tabs required in each case may be displayed. However, in order for the user to directly select a tab, the tabs are displayed in order in accordance with the user's instruction in the tab display area.

  The item display tab clear display processing unit 23 in the tab display processing unit 22 understands at a glance about the tabs currently displaying items on the display unit 26 among the plurality of tabs displayed on the display unit 26. It is displayed clearly by various methods. In this case, for example, various methods such as displaying a specific tab brighter than other tabs, displaying it larger, or displaying it darker can be employed. The display unit 26 of FIG. 1 shows a reduced display state of FIG. 5A to be described later, but FIG. 1 shows an example in which tabs “A to E” are clearly displayed. .

  The item display processing unit 24 of the search screen display processing unit 21 displays items included in the tabs that are clearly displayed as described above, and displays them using the list created by the display item list creation unit 6. be able to. The items in the range included in a specific tab are displayed here, but there are still many items that can exist, so they are not displayed by operations such as rotating the jog in this state. Items can be displayed in order. At that time, when only a part of the items are present in the display item list creation unit 6, the item capturing unit 3 in the selection tab captures data from the external audio device 27 and displays the list in accordance with the operation of the jog. It will be.

  The cursor movement display processing unit 25 of the search screen display processing unit 21 displays a cursor by various methods in order to display the items selected by the user in an easy-to-understand manner. In that case, for example, a method of surrounding the selected item display with a red frame can be adopted.

  In this invention which consists of the above functional blocks, it can implement by various methods by the operation | movement flow as shown, for example in FIGS. Hereinafter, description will be made with reference to various display examples and operation examples in FIGS. 1 and 5 to 10. In the tab use search process shown in FIG. 2, a search function use instruction is first given by the user (step S1), and then a tab divided into a plurality of parts is displayed (step S2). The tabs displayed here can be set in various ways and according to various attributes. In the example shown in FIG. 5A, when searching for an artist, artist names “A to E”, “ This is divided into “F to J”, “K to O”, “P to T”, “U to Z”, and “Other”, and this is displayed on the upper right of the screen. In the example of FIG. 5A, since it is narrow to display all these tabs, only “A to E”, “F to J”, and “K to O” are displayed, and thereafter there are more tabs. After that, they are displayed in order by moving the cursor.

  After that, a specific tab is selected, items in the range of the selected tab are displayed, and a cursor is displayed on an arbitrary item. In the example shown in FIG. 5A, in order to show that items included in the tabs “A to E” are displayed, this tab is displayed so as to be clearer than others. For example, the selected tab is displayed. Is displayed in a bright color that is larger than the others and different from others. Further, for the items displayed in alphabetical order on the display unit, an easy-to-understand display different from others, for example, a red frame display is performed on an item designated by the user or an automatically selected item. These tab display, item display, and cursor display for the items are performed by the search screen display processing unit 21 in FIG.

  In the example shown in FIG. 1, it is then determined whether or not a forward search has been performed (step S4). Here, the search method instruction unit 10 of the user selection instruction input unit 7 in FIG. 1 determines which instruction the user has given, and performs forward search by detecting, for example, pressing the right side of the jog. Detect what you indicated. In that case, the process proceeds to step S5, and thereafter, a forward search process is performed.

  On the other hand, if it is determined in step S4 that the search instruction is not a forward direction, the process proceeds to step S11 to perform a backward search to determine whether or not the market price is appropriate. Here, when it is determined that there is an instruction to perform a backward search by pressing the left side of the jog or the like, the process proceeds to step S12 and the backward search process as shown in FIG. 3 is performed. On the other hand, when it is determined in step S11 that the reverse direction search instruction has not been issued, the process proceeds to step S13 in the illustrated example, and tab direct instruction search processing as shown in FIG. 42 is performed.

  However, when there is an instruction to perform a tab direct instruction in the search method instruction unit 10 of FIG. 1, the process of step S13 is performed immediately without performing the determination as in steps S4 and S11 as described above. It can be performed. The same applies to step S11 when detecting such a direct user instruction.

  When a forward search process is performed in step S5 in FIG. 2, a tab next to the currently displayed tab is selected, and an item belonging to the tab is searched. In this process, when the tab selection unit 15 in FIG. 1 performs the selection process in the forward tab selection unit 16 as described above, the tab next to the currently displayed tab is selected, and the selected tab is selected. The internal item capturing unit 3 captures items belonging to the tab range from the external audio device 27.

  If it is determined that an item exists in the selected tab range, a list of items belonging to the tab is created and displayed for the tab in which the item exists, and the cursor is moved to the first item. At the same time, the tab corresponding to the item being displayed is clearly displayed. This state is illustrated in FIG. 5B. In this figure, the tab “F to J” is currently selected, and the items within the tab range are displayed in alphabetical order from the top, especially the top item. The cursor is moved and displayed.

  When it is determined in step S7 that there are no items in the selected tab range, it is determined in the example of FIG. 1 whether or not all tabs have been selected (step S8), and not all tabs have been selected yet. If it is discriminated, the process returns to step S6, the next tab is selected and a search is performed, and thereafter the same operation is repeated. If it is determined in the process that all tabs have been selected in step S8, the screen at the start of search is displayed in the illustrated example (step S9). Accordingly, in the example of FIG. 5, the same screen as in FIG. 5A is displayed as shown in FIG.

  The operation at the time of the forward search is performed as described above, for example, by performing the operation as shown in FIG. That is, in the example shown in FIG. 6, when there are items as shown in FIGS. 6A and 6A, all the artist names that are further in the alphabetical order are displayed on the first “A to E” tab. From the state where “All” to “CCC” for selection are displayed, an instruction to perform forward search is made by pressing the right side of the jog or the like. As a result, the items in the range of the next tab “F to J” are searched in the search direction as shown in FIGS.

  As a result, in the example of the figure, since “FFF”, “GGG”, and “HHH” exist, at least one item exists, so the display of the tabs “F to J” and the items included in the range are displayed. Will be performed. This is the display process in step S10 in FIG. 1, and corresponds to the process in FIG.

  Further, in the example in which items as shown in FIGS. 6B and 1A exist, items “All”, “AAA”, “BBB”, and “CCC” in the range of tabs “A to E” are initially displayed. When the next tab “F to J” is selected in accordance with the forward search instruction, the search is performed as shown in FIGS. 2B and 2B and the items within the range of the tab are searched. However, in this example, since there is no item within the range of the tab, the next tab is further searched in steps S7 to S8 (N) and step S6 in FIG. Accordingly, the presence of “KKK” is detected, the tabs “K to O” are clearly displayed, and items “KKK”, “LLL”, “MMM}” and “NNN” within the range of the tab are displayed. Become.

  Further, in the case of data as shown in FIGS. 6C and 6A, all items are included in the range of this tab by first selecting the tabs “A to E”. Therefore, when a forward search is performed in the same manner as described above, a search as shown in (c) and (2) of FIG. 8 is performed, and there is no item in the range of the next tab “F to J”. Even if a search is performed for all tabs, no items exist, so a screen display at the start of the search is performed. This operation is finally performed in step S9 of FIG. 1, and in the example of FIG. 5, the display as shown in FIG. At this time, the cursor may be moved and displayed at “All”.

  As shown in FIG. 3, the backward search process in step S12 of FIG. 2 first performs a search by selecting a tab before the currently selected tab (step S21). This processing is performed when the user can select a desired artist earlier in the reverse direction instruction unit 12 of the search method instruction unit 10 of the user selection instruction input unit 7 in FIG. When the user thinks, the reverse direction indicating unit 12 inputs an instruction to that effect. At this time, in the tab selection unit 15, the reverse tab selection unit 18 operates to select a tab in the reverse direction of the currently displayed tab.

  Next, it is determined whether or not an item exists in the selected tab range (step S22). When it is determined that the tab exists, the tab in which the item exists is stored in the example shown in FIG. 3 (step S23), and then the tab further before the selected tab is selected and searched (step S24). It is determined whether or not an item exists in the range of the tab selected in step S25. When it is determined that the item exists in the range of the selected tab, the process proceeds to step S30, where the item list of the tab that has been selected previously is displayed, the cursor is moved to the first item, and the display Clearly display the tab to which the item belongs.

  That is, when it is determined that an item exists in the tab selected in step S25, the tab is immediately clearly displayed, a list of items included therein is created, and displayed on the display unit from the top of the list. Although it can be implemented, there are actually so many items in one tab, so if you perform a backward search as it is, it will be too many to search to the top of that tab and display the list in order on the display. Expected to take time.

  Therefore, when searching from the reverse side of the selected tab, if one item is found, this tab is temporarily stored, and the previous tab is immediately selected to search from the reverse direction. When an item is found on that tab, the item immediately before that item is the first item included in the tab where the item was found and stored first. Efficient search and display processing can be performed.

  At this time, when it is determined that there is no item in the tab immediately before the tab in which the item has been found earlier, the process proceeds to step S26, and the previous tab is further selected and searched. Here again, it is determined whether or not an item exists in the selected tab. If it is determined that an item exists in the selected tab, the process proceeds to step S30, and the same display processing as described above is performed.

  If it is determined in step S27 that there are no items in the tab selected again, it is determined in step S28 whether or not all tabs have been selected. If it is determined that all tabs have not yet been selected, the process proceeds to step S26. Return and repeat the above operation. On the other hand, when it is determined in step S28 that all tabs have been selected, the process proceeds to step S29 in the illustrated example. In step S29, the item list of the tab that has been previously selected and displayed is displayed after the item “Display all items”, the cursor is moved to “Display all items”, and the tab is “All items”. “A to E” to which “display” belongs are clearly displayed.

  That is, when only one tab in which an item exists is found in step S22, there are only two tabs, the currently displayed tab and the currently found tab, so that it is easier to search if all the artists are displayed. It is determined that there is an image, and “All” for displaying all artists is selected. In particular, there is a tab of “Other” that does not belong to other tabs, and when this is initially displayed, it is unlikely that there will be a lot of data on this tab, so select “All” In the above example, the cursor is moved to “All” which means “display all items”. However, only the tab items that are found and stored in advance may be displayed.

  As a result of the above processing, the display shown in FIG. 7A, that is, the “Other” tab is first selected, and most of the data should be within the alphabet range. When the starting item is displayed, in the most standard example of step S30, as shown in FIG. 5B, the tabs “U to Z” that are the tabs before the “Other” tab are clearly displayed. The items included in the tab are displayed as a list.

  On the other hand, when it is found in step S29 that the item exists only in one other tab, as shown in FIG. 7C, after “All” is displayed, the other items found this time are displayed. The items in the range of “U to Z” that are tabs are displayed, and the tab clearly displays “U to Z” to which the next item of “All” does not belong to any tab, and the cursor is “All”. It has moved to.

  If it is determined in step S22 in FIG. 3 that there are no items in the selected tab range, the process proceeds to step S31, where it is determined whether all tabs have been selected, and all tabs have not yet been selected. When it is determined, the previous tab is further selected and searched (step S32), and the process returns to step S22. Here, it is determined again whether or not the item exists in the selected tab range, and if it exists, the process proceeds to step S23 and the above operation is repeated. If it is determined that the tab does not exist, the process proceeds to step S31 to repeat the above operation. If it is determined that all tabs are selected in step S31 in the process, a screen for starting the search is displayed in step S33.

  As a result, in the example of FIG. 7, the first screen as shown in FIG. However, it is also possible to display “All” again, display a list of items belonging to “Other”, move the cursor to “All”, and clearly display “Other” on the tab.

  These search operations are performed as shown in FIG. That is, in the example shown in FIG. 8, when “++” belonging to the “Other” tab is selected in the data as shown in FIGS. A search is performed, and the item “ZZZ” is found first, so that “TTT” is found as a result of searching the tab “P to T” that is the tab before the tab “U to Z” to which this item belongs. Then, “UUU” that is the item before “TTT” can be found immediately, and finally a list of items starting with this “UUU” is displayed. This display processing is performed in step S30 in FIG. 3, and a display as shown in FIG. 7B is made.

  When the same display as (a) and (1) in the first (1) is made in FIG. 8B, the result of searching in the reverse direction is the same as the above (2). Example of displaying all from "All" in the first tab when "ZZZ" in the range of "U to Z" is found, but the previous tab is not found as a result of searching the previous tab. Is shown. This display processing is performed in step S29 in FIG.

  In FIG. 8C, when the cursor is first moved and displayed at “1234”, the result of the search according to the reverse search instruction indicates that there are no items on the other tabs. The display screen is maintained. This process is performed in step S33 of FIG. 3, and the display of FIG. 7D is made.

  As shown in FIG. 4, the tab direct instruction retrieval process performed in step S13 in FIG. 2 starts when the first user designates an arbitrary tab (step S41). Thereafter, it is determined whether or not the designated tab is a currently displayed tab. When the currently displayed tab is selected, a beep sound indicating that the operation is wrong is output to the user (step S46). ). This operation is performed by outputting a beep sound in the beep sound output unit 14 of FIG. 1 when the tab specified by the tab direct instruction unit 3 of the user selection instruction input unit 7 matches the currently displayed tab. Is going.

  When it is determined in step S42 that the designated tab is not the currently displayed tab, the designated tab is searched in the forward direction in the illustrated example (step S43). Next, it is determined whether or not an item exists in the designated tab (step S44). If there is an item, a list of items in the designated tab range is displayed, the cursor is moved to the first item, and the designated tab is clearly displayed. (Step S45). On the other hand, when it is determined in step S44 that no item exists in the designated tab, the screen at the start of search is kept displayed (step S47).

  The screen display example at this time is as shown in FIG. 9, when the same display as in FIG. 5A is initially performed as shown in FIG. 9A, the user selects tabs “F to J”. When there is an item directly when instructed directly, the display as shown in FIG. This operation is performed in step S45 of FIG. On the other hand, when it does not exist, the initial screen display is maintained as shown in FIG. This operation is performed in step S47 of FIG.

  The search operation at that time is as shown in FIG. 10, when the cursor is first moved to “BBB” in the range of the tabs “A to E” and the user designates the tab “F to J”. In addition, since items including “FFF” are searched, the cursor is moved to the first item “FFF” and displayed, and the tab clearly displays “F to J”. This operation is performed in step S45 of FIG. 4 and is performed as shown in FIG. 9B. On the other hand, when there is no item corresponding to the selected and designated tabs “F to J”, the initial display is maintained as shown in FIG. This operation is performed in step S47 of FIG. 4, and a display as shown in FIG.
