  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a block diagram showing a configuration of a data processing apparatus according to an embodiment of the present invention.

  The data processing apparatus can be applied not only to a computer but also to an in-vehicle music reproducing apparatus that combines car navigation, car audio, and the like.

  The data processing apparatus 1 according to the present embodiment includes a USB connector 12a for connecting a USB memory 32, an SD slot 12b for connecting an SD (Secure Digital) card 34, a DVD / CD for reading music data of a DVD or CD. Digital audio signals read from the CD drive 36, the USB connector 12a, the SD connector 12b, the I / F unit 14 connected to the DVD / CD drive 36, the USB memory 32, the SD card 34, or the DVD / CD drive 36 are converted into analog audio. An input from a user including a digital / analog converter (DAC) 16 for converting the signal, an amplifier 18 for amplifying the analog audio signal, a speaker 20 for converting the amplified audio signal into audible sound, a touch panel, a remote controller (not shown), and the like. Receive A first display unit 24 (display unit) and a second display unit 30 (display unit) for displaying a database related to music data included in the input unit 22, USB memory 32, SD card 34 or DVD or CD, USB memory 32, It has a memory 26 (storage means) for storing data and database read from the SD card 34 or DVD or CD, and a microcontroller 28 (search means, control means, registration means) for controlling each part.

  The memory 26 is composed of, for example, a hard disk or a non-volatile memory. The microcontroller 28 includes a RAM / ROM 28a (temporary storage means) and a CPU 28b. The input unit 22 includes various operation buttons and the like. The first display unit 24 is a front seat occupant display unit, and the second display unit 30 is a rear seat occupant display unit.

  When the USB memory 32 is connected to the USB connector 12a according to the program stored in the internal RAM / ROM 28a, the microcontroller 28 recognizes the connection of the USB memory 32 and accordingly stores the music stored in the USB memory 32. It has a function to automatically create a database about data. Similarly, according to the program stored in the internal RAM / ROM, the microcontroller 28 recognizes the connection of the SD card 34 when the SD card 34 is connected to the SD slot 12b, and stores it in the SD card 34 accordingly. Provided with a function for automatically creating a database relating to the recorded music data. Further, according to the program stored in the internal RAM / ROM, when the DVD or CD is set in the DVD / CD drive 36, the microcontroller 28 recognizes that the DVD or CD is set, and accordingly the DVD Alternatively, it has a function of automatically creating a database relating to music data stored on a CD. The created database is stored in the memory 26 and is immediately used for user data retrieval.

  Note that the format of the music file may be a WAV format or a compression format such as MP3 or WMA.

  FIG. 2 is a diagram illustrating an example of a music file stored in the USB memory 32. All music files stored in the USB memory 32 belong to the genre A.

  The music file may be stored in the SD card 34, DVD, CD, or the like. Hereinafter, an example in which the music file is stored in the USB memory 32 will be described.

  FIG. 3A is a diagram illustrating a database search result when genre A is a keyword, and FIG. 3B is a diagram illustrating an example of the database. A database search result when the genre A is a keyword shown in FIG. 3A is displayed on the first display unit 24 or the second display unit 30.

  The database includes genre name, file name, and information on the date and time when the music file copy is completed. The database may include information such as artist names and album names related to the music file.

  FIG. 4 is a flowchart showing the processing executed by the microcontroller 28 during the database search.

  For example, the microcontroller 28 searches the database using the genre A as a keyword. As a search result, as shown in FIG. 3A, file names for three music files are displayed on the second display unit 30 (step S1). At this time, it is assumed that the microcontroller 28 has not completed the search process, and sequentially displays on the second display unit 30 from the result of the first hit of the keyword.

  Next, the USB memory 32 is connected to the USB connector 12a, and an instruction to start copying the music file stored in the USB memory 32 is input from the first display unit 24 (step S2). At this time, the microcontroller 28 temporarily stores the copy start date and time in the RAM / ROM 28a.

  Then, the microcontroller 28 copies the n-th song (n = 1, 2, 3,...) Of the music file stored in the USB memory 32 to the memory 26, and when it completes (step S3), The genre name, file name, and copy completion date / time are registered in the database (step S4). Note that the genre name, file name, and copy completion date / time of the music file are registered in the database each time copying of each music file is completed. FIG. 5 shows an example of the database after completion of copying. Here, the file names are registered in the database in alphabetical order.

  Thereafter, the microcontroller 28 assigns a date / time condition for displaying the file name registered in the database before the start of copying to the file name display condition (step S5). The second display unit 30 updates the search result display screen based on the display conditions (step S6). Here, the date / time condition is a copy start date / time temporarily stored in the RAM / ROM 28a. Thus, in steps S5 and S6, the microcontroller 28 causes the second display unit 30 to display only the file names registered in the database before the copy start date and time as search results.

  For example, if the copy start date and time is 10: 9: 0 on May 5, 2007, the file names to be displayed are “AAA.mp3” and “ACE.mp3” in the database of FIG. , "AEG.mp3", ..., "ZZZ.mp3". The file names “ABC.mp3” and “DEF.mp3” are not displayed because the copy end date and time are later than the copy start date and time. At this time, the search result displayed on the second display unit 30 is the same as that in FIG.

  Next, the microcontroller 28 determines whether or not the copy processing of all the music files stored in the USB memory 32 has been completed (step S7). If YES in step S7, the copy process ends. On the other hand, if NO in step S7, the process returns to step S3.

  FIG. 6 is a flowchart showing the processing executed by the microcontroller 28 when the rear seat occupant scrolls the search result displayed on the second display unit 30.

  The microcontroller 28 adds a date and time condition (before the copy start date and time) to the display condition of the file name for the file names for the number of songs that are currently displayed on the second display unit 30 and remain on the display screen after scrolling. The file name is acquired from the database (step S11).

  On the other hand, the microcontroller 28 is not currently displayed on the second display unit 30, and after scrolling, the file names for the number of songs newly displayed on the display screen are set to the date / time condition (copy) for the file name display condition. The file name is acquired from the database in accordance with the registration order of the file name without assigning (start date and time) (step S12).

  Thereafter, the microcontroller 28 creates a display list from the file name currently displayed on the second display unit 30 and the file name newly displayed on the second display unit 30 (step S13). The second display unit 30 updates the search result display screen based on the display list (step S14), and ends the process.

  For example, FIG. 7A shows an example in which the file name is scrolled up by one from the state of FIG. In this case, as shown in FIG. 5, the file name “ABC.mp3” is registered next to the file name “AAA.mp3” in the database, but after the file name “ACE.mp3” is scrolled, The file name "ABC.mp3" added by copying remains on the display screen.

  A method of creating a display list when the file name is scrolled up by one from the state of FIG. 3A, that is, a method of creating an updated display list of FIG. 7A will be described.

  First, the microcontroller 28 searches the database for a registered position of the file name “AAA.mp3” based on the display condition. Next, the microcontroller 28 assigns a date and time condition (before the copy start date and time) to the display conditions of the file names “AAA.mp3” and “ACE.mp3”, and from the registered position on the database of the file name “AAA.mp3”. Get the file names for two songs. After that, the microcontroller 28 does not give the date / time condition (before the copy start date / time) to the display condition of the new file name, and one song from the position immediately before the registration position on the database of the file name “AAA.mp3”. Get the file name for minutes. Finally, the microcontroller 28 creates a list using the acquired file names.

  On the other hand, FIG. 7B shows an example in which the file name is scrolled downward by one from the state of FIG. In this case, as shown in FIG. 5, the file name “DEF.mp3” is registered in the database after the file name “AEG.mp3”. The file name “DEF.mp3” added by copying is displayed without adding the date / time condition (before the copy start date / time) to the display condition.

  A method of creating a display list when the file name is scrolled down from the state of FIG. 3A, that is, a method of creating the updated display list of FIG. 7B will be described.

  First, the microcontroller 28 searches the database for a registered position of the file name “ACE.mp3” based on the display condition. Next, the microcontroller 28 assigns a date and time condition (before the copy start date and time) to the display conditions of the file names “ACE.mp3” and “AEG.mp3”, and from the registered position on the database of the file name “ACE.mp3”. Get the file names for two songs. After that, the microcontroller 28 does not give the date / time condition (before the copy start date / time) to the display condition of the new file name, and one song from the position two behind the registration position on the database of the file name “ACE.mp3”. Get the file name for minutes. Finally, the microcontroller 28 creates a list using the acquired file names.

  In step S12 of FIG. 6, the microcontroller 28 is not currently displayed on the second display unit 30, and after scrolling, the file names corresponding to the number of music pieces newly displayed on the display screen are also displayed. A date and time condition (before the copy start date and time) may be assigned to the display condition, and the file name may be acquired from the database. In this case, the file name of the copied music file is not displayed even if it is scrolled.

  As described above in detail, the memory 26 stores the music file and the file name (music file information), the microcontroller 28 searches the file name of the music file stored in the memory 26, and displays the second display. The unit 30 displays the search result by the microcontroller 28. When the music file stored in the USB memory 32 is copied to the memory 26 during the search for the file name, the microcontroller 28 corresponds to the music file stored in the memory 26 before the start of the copying. The second display unit 30 is controlled so that the search result of the file name is displayed. Therefore, when the music file stored in the USB memory 32 is copied to the memory 26 during the search for the file name, the search result of the file name corresponding to the music file stored in the memory 26 before the copy is started. Since it is displayed, it is possible to prevent the music file from being reproduced or selected by the user.

  The memory 26 includes a database for managing file names. The RAM / ROM 28a temporarily stores the copy start date and time when a music file stored in the USB memory 32 is copied to the memory 26. The microcontroller 28 Register the file name and copy completion date and time in the database. When the music file stored in the USB memory 32 is copied to the memory 26 during the file name search, the microcontroller 28 corresponds to the music file having a copy completion date and time earlier than the copy start date and time. The second display unit 30 is controlled so that the search result of the file name is displayed. Therefore, since the search result of the file name corresponding to the music file having the copy completion date and time earlier than the copy start date and time is displayed, it is possible to prevent the music file from being reproduced and selected by the user.

  Further, the number of file names that are not currently displayed on the second display unit 30 and are newly displayed on the second display unit 30 after scrolling include the file names registered in the database after the start of copying ( Steps S12 to S14, see FIG. 7B). The number of file names newly displayed on the second display unit 30 after scrolling is changed to the number of file names displayed on the second display unit 30 in the database after the start of copying. Even if the information of the registered music file is included, it is not possible to perform reproduction or selection of the music file that is not intended by the user, and to provide the user with an environment in which the latest music file can be reproduced or selected.

  The number of file names that are currently displayed on the second display unit 30 and remain on the second display unit 30 after scrolling include the file names registered in the database before the start of copying. That is, after scrolling, the number of file names that are displayed on the second display unit 30 does not include the file names registered in the database after the start of copying. Can be prevented.

(Second Embodiment)
In the first embodiment, in order to display only the file names registered in the database before the copy start date and time, the copy end date and time of each music file is registered in the database. In the present embodiment, the file name registered in the database is identified before starting copying by setting a flag on the file name of the music file being copied.

  FIG. 8 is a diagram illustrating an example of a database.

  The database includes genre name, file name, and copy flag information. The database may include information such as artist names and album names related to the music file.

  FIG. 9 is a flowchart showing the processing executed by the microcontroller 28 during the database search.

  For example, the microcontroller 28 searches the database using the genre A as a keyword. As a search result, as shown in FIG. 3A, file names of three music files are displayed on the second display unit 30 (step S21). At this time, it is assumed that the microcontroller 28 has not completed the search process, and sequentially displays on the second display unit 30 from the result of the first hit of the keyword.

  Next, the USB memory 32 is connected to the USB connector 12a, and an instruction to start copying the music file stored in the USB memory 32 is input from the first display unit 24 (step S22).

  Then, the microcontroller 28 copies the n-th song (n = 1, 2, 3,...) Of the music file stored in the USB memory 32 to the memory 26, and when it is completed (step S23), The genre name, file name, and copy flag are registered in the database (step S24). Note that the genre name, file name, and copy flag of a music file are registered in the database sequentially each time copying of each music file is completed. FIG. 10 shows an example of the database after completion of copying. Here, the file names are registered in the database in alphabetical order. The copy flag corresponding to the file name just registered in the database is set to “valid”. The database is updated so that all the copy flags become “invalid” as soon as the file name search function is canceled. In other words, if a music file is copied during a file name search, the settings of “valid” and “invalid” are mixed in the copy flag column of the database until the file name search function is canceled.

  Thereafter, the microcontroller 28 assigns a condition for excluding the file name for which the copy flag is set to “valid” to the display condition of the file name (step S25). The second display unit 30 updates the search result display screen based on the display conditions (step S26). In this manner, in steps S25 and S26, the microcontroller 28 causes the second display unit 30 to display only the file name for which the copy flag is set to “invalid” as the search result.

  Next, the microcontroller 28 determines whether or not the copy processing of all the music files stored in the USB memory 32 has been completed (step S27). If YES in step S27, the copy process ends. On the other hand, if NO in step S27, the process returns to step S23.

  FIG. 11 is a flowchart showing a process executed by the microcontroller 28 when the occupant of the rear seat scrolls the search result displayed on the second display unit 30.

  The microcontroller 28 is currently displayed on the second display unit 30, and after scrolling, the copy flag is set to “valid” in the file name display condition for the file names for the number of songs remaining on the display screen. A condition for excluding the file name from the display target is assigned, and the file name is acquired from the database (step S31).

  On the other hand, the microcontroller 28 is not currently displayed on the second display unit 30, and after scrolling, for the file names corresponding to the number of songs to be newly displayed on the display screen, the copy flag is set in the display condition of the file name. The file name is acquired from the database in accordance with the registration order of the file name without giving a condition for excluding the file name set to “valid” from the display target (step S32).

  Thereafter, the microcontroller 28 creates a display list from the file name currently displayed on the second display unit 30 and the file name newly displayed on the second display unit 30 (step S33). The second display unit 30 updates the search result display screen based on the display list (step S34), and ends the process.

  When this process is executed, when the file name is scrolled up by one from the state shown in FIG. 3A, the updated display list shown in FIG. Is displayed. On the other hand, when the file name is scrolled down by one from the state of FIG. 3A, the updated display list of FIG.

  Further, in step S32, the microcontroller 28 is not currently displayed on the second display unit 30, and after scrolling, file name display conditions for file names corresponding to the number of songs newly displayed on the display screen are also displayed. The file name for which the copy flag is set to “valid” may be added to the display target, and the file name may be acquired from the database. In this case, the file name of the copied music file is not displayed even if it is scrolled.

  As described above in detail, according to the present embodiment, the memory 26 includes a database for managing file names, and the microcontroller 28 stores the file names in the database before the start of copying and copying. Register a copy flag that specifies the file name of the music file that does not exist as a display object. Then, when the music file stored in the USB memory 32 is copied to the memory 26 during the search for the file name, the microcontroller 28 selects the file name corresponding to the music file that is not excluded from the display target due to the copy flag. The second display unit 30 is controlled so that the search results are displayed.

  Therefore, the search result of the file name corresponding to the music file that is not stored in the memory 26 before the start of copying is excluded from the display target via the copy flag. Can be prevented.

(Third embodiment)
In this embodiment, by registering the file name of the music file being copied in the sub-database, the file name registered in the (main) database is identified before starting the copy. The sub-database is stored in the memory 26.

  FIG. 12 is a flowchart showing processing executed by the microcontroller 28 during the database search.

  For example, the microcontroller 28 searches the database using the genre A as a keyword. As a search result, as shown in FIG. 3A, the file names of three music files are displayed on the second display unit 30 (step S41). At this time, it is assumed that the microcontroller 28 has not completed the search process, and sequentially displays on the second display unit 30 from the result of the first hit of the keyword.

  Next, the USB memory 32 is connected to the USB connector 12a, and an instruction to start copying the music file stored in the USB memory 32 is input from the first display unit 24 (step S42).

  Then, the microcontroller 28 executes copying of the nth song (n = 1, 2, 3,...) Of the music file stored in the USB memory 32 to the memory 26, and when it is completed (step S43), The genre name and the file name are registered in the sub database (step S44). Note that the genre name of the music file and the registration of the file name in the sub-database are sequentially executed every time copying of each music file is completed. The sub-database is joined to the database as soon as the file name search function is released.

  Next, the microcontroller 28 determines whether or not the copy processing of all the music files stored in the USB memory 32 has been completed (step S45). If YES in step S45, the copy process ends. On the other hand, if NO in step S45, the process returns to step S43.

  In this way, according to this process, even if the music file is copied during the file name search, the file name of the copied music file is not reflected in the database at that time. File playback and selection can be prevented.

  FIG. 13 is a flowchart illustrating processing executed by the microcontroller 28 when the rear seat occupant scrolls the search result displayed on the second display unit 30.

  The microcontroller 28 acquires the file names from the database according to the search key for the file names for the number of songs that are currently displayed on the second display unit 30 and remain on the display screen after scrolling (step S51).

  On the other hand, the microcontroller 28 is not currently displayed on the second display unit 30, and after scrolling, the file names corresponding to the number of songs newly displayed on the display screen are stored in the sub-database according to the search key. Obtained from the combined database (step S52).

  Thereafter, the microcontroller 28 creates a display list from the file name currently displayed on the second display unit 30 and the file name newly displayed on the second display unit 30 (step S53). The second display unit 30 updates the search result display screen based on the display list (step S54), and ends the process.

  When this process is executed, when the file name is scrolled up by one from the state shown in FIG. 3A, the updated display list shown in FIG. Is displayed. On the other hand, when the file name is scrolled down by one from the state of FIG. 3A, the updated display list of FIG.

  In addition, the microcontroller 28 obtains the file names from the database according to the search key for the file names corresponding to the number of songs newly displayed on the display screen after scrolling, which are not currently displayed on the second display unit 30. You may make it do. In this case, the file name of the copied music file is not displayed even if it is scrolled.

  As described in detail above, according to the present embodiment, the memory 26 stores the database that manages the file name corresponding to the music file stored in the storage means before the start of copying, and the storage after the start of copying. And a sub-database for managing file names corresponding to the music files stored in the means. When the music file stored in the USB memory 32 is copied to the memory 26 during the search for the file name, the microcontroller 28 uses the database to store the music file before starting the copy. The second display unit 30 is controlled so that the search result of the file name corresponding to the music file is displayed.

  Therefore, the registration destination of the file name is divided into the sub-database and the database according to the music file to be registered, and the music file stored in the USB memory 32 is copied to the memory 26 during the file name search. Since a database that manages file names corresponding to music files stored in the memory 26 before the start of copying is used, reproduction and selection of music files that are not intended by the user can be prevented.

  Further, the number of file names that are not currently displayed on the second display unit 30 and are newly displayed on the second display unit 30 after scrolling include the file names registered in the database and the sub-database. Therefore, since the user sees the number of file names newly displayed on the second display unit 30 after scrolling for the first time, the user intends even if the file name registered in the sub-database is included in the file name. It is possible to provide the user with an environment in which the latest music file can be played and selected without being played or selected.

  Further, the number of file names that are currently displayed on the second display unit 30 and remain on the second display unit 30 after scrolling include only the file names registered in the database. Therefore, since the file name registered in the sub-database is not included, it is possible to prevent the reproduction and selection of the music file that is not intended by the user.

  In the first to third embodiments described above, the music file search process has been described. However, the search target file is not limited to music, and may be a file such as a still image, a moving image, or a document.

  Further, the first to third embodiments described above can be applied when a music file is copied during a file name search. For example, while an occupant of a front seat searches for a file name registered in an in-vehicle hard disk, the occupant connects an external medium in which a music file is stored to the connection terminal of the external medium, and automatic copying is performed. When it is executed, or while the rear seat occupant is searching for a file name registered on the in-vehicle hard disk, the front seat occupant starts copying the music file stored in the external medium on the in-vehicle hard disk. In this case, the first to third embodiments described above can be applied.

  In the first embodiment, the date and time condition is a copy start date and time temporarily stored in the RAM / ROM 28a, but may be a copy start date or a copy start time.

  A recording medium in which a software program for realizing the functions of the data processing device 1 is recorded is supplied to the data processing device 1, and the microcontroller 28 reads out and executes the program stored in the storage medium. Also, the same effects as those of the above embodiment can be obtained. Examples of the storage medium for supplying the program include a CD-ROM, a DVD, or an SD card.

  In addition, the same effect as that of the above embodiment can be obtained when the microcontroller 28 of the data processing device 1 executes a software program for realizing the functions of the data processing device 1.

  The present invention is not limited to the above-described embodiment, and can be implemented with various modifications within a range not departing from the gist thereof.
