  In general, in a playback apparatus, a music to be played back is selected by a user operating various controls. However, this reproducing apparatus has a problem that a user has to select a desired piece of music every time a medium to be reproduced is inserted, which is burdensome for a user who is unfamiliar with the operation. For this reason, conventional playback apparatuses often have a function of arbitrarily selecting music to be played back, but this function is often not used. Furthermore, considering the recent trend in which the number of operators increases with the increase in the number of functions of the playback device, this problem can be said to be even more serious.

  The present invention has been made in view of the circumstances described above, and an object of the present invention is to provide a music playback control device and a music playback control program that can reduce the burden of the user selecting a favorite music. .

  In order to solve the above-mentioned problems, the present invention provides a storage medium processing means for outputting any of a plurality of music data stored in a storage medium to a sound output device that outputs a musical sound based on music data, And when the music data is output to the sound output device by the storage media processing means, the music data and reproduction history data indicating the output time point are stored in the storage means, while a music reproduction instruction is issued. Provided with control means for reading out music data whose time point indicated by the reproduction history data satisfies a predetermined condition from the music data stored in the storage means and outputting the music data to the sound output device. Is a music reproduction control device.

  According to this configuration, the music data reproduced from the storage medium is stored together with the reproduction history data in the storage means, and among the music data stored in the storage means, the time point indicated by the reproduction history data satisfies a predetermined condition. The music data to be satisfied is selectively played back. Therefore, for example, by designating a period or a time zone, music data that has been reproduced at a certain point in the past can be easily selected.

  According to the present invention, the music or album to be stored in the storage means is selected according to the output status of the music data stored in the storage medium. Can reduce the burden.

  Embodiments of the present invention will be described below with reference to the drawings. Such an embodiment shows one aspect of the present invention, and does not limit the present invention, and can be arbitrarily changed within the scope of the present invention.

The hard disk device 18 in the present embodiment stores a music playback control program in which instructions related to music playback operations are arranged as an application program. Further, the hard disk device 18 has a storage area to which music data stored in the CD 131 or the MD 141 is transferred. Which of these music data is transferred to the hard disk device 18 depends on the operation mode of the music playback device. Hereinafter, this operation mode will be described in detail.

<A-2: Operation mode>
The operation mode of the music reproducing apparatus according to the present embodiment includes a music collection creation mode and an album collection creation mode, and the user can arbitrarily select one of them. Hereinafter, each of these modes will be described in detail.

(1) Music Collection Creation Mode This operation mode is a mode in which a song collection is created by automatically determining a favorite song of the user. That is, in the music collection creation mode, the music data stored in the CD 131 or MD 141 that satisfies a predetermined condition is automatically stored in the hard disk device 18. In the present embodiment, the following four conditions corresponding to the music playback time are prepared in advance as the predetermined condition, and any one of them is selected by the user. In the initial state, it is assumed that the third condition Ca3 is selected from the following conditions. The first condition Ca1 is that the music has been reproduced even a little. The second condition Ca2 is that the music has been played for over 1 minute. The third condition Ca3 is that the music has been played for 2 minutes or more. The fourth condition Ca4 is that the music has been played to the end.

  More specifically, among the music data stored in the CD 131 or the MD 141, it is determined that the music data that has been played over the time according to the set condition corresponds to the user's favorite music. And stored in the hard disk device 18. At this time, as shown in FIG. 2, the hard disk device 18 stores the index data and the reproduction history data together with the music data satisfying the conditions. Of these, the index data is data for specifying the music data, and an identifier (hereinafter referred to as “disc ID”) uniquely assigned to the storage medium storing the music data, and the music data are: Information (hereinafter referred to as “music number”) indicating which music data corresponds to the music data among the plurality of music data stored in the storage medium. This index data is specified based on TOC (Table Of Contents) information stored in the storage medium. On the other hand, the reproduction history data is data indicating the reproduction contents of the music data in the past, the number of times the music data has been reproduced in the past, and the accumulated time (hereinafter referred to as “total reproduction time”). And). As described above, in the music collection creation mode, a set of the music data, the index data, and the reproduction history data is stored in the hard disk device 18 for each music satisfying a preset condition, and a music collection is created. It is done.

(2) Album collection creation mode This operation mode is a mode in which the user's favorite album is automatically determined and the music data is stored in the hard disk device 18 in units of albums (units of storage media such as CD 131 and MD 141). is there. That is, in the album collection creation mode, albums that satisfy a predetermined condition (that is, all music data stored in this storage medium) are automatically stored in the hard disk device 18. In the present embodiment, the following three conditions are prepared in advance according to the number of music data actually played out of the music data constituting the album as the predetermined condition. To be selected. In the initial state, it is assumed that the second condition Cb2 is selected from the following conditions. The first condition Cb1 is that two or more pieces of music data included in the album are reproduced. The second condition Cb2 is that five or more pieces of music data included in the album are reproduced. The third condition Cb3 is that all music data included in the album is reproduced.

  More specifically, when the number of music data actually played out of the music data constituting the album exceeds the number according to the set condition, the album is an album that matches the user's preference. It is determined and stored in the hard disk device 18. At this time, as shown in FIG. 3, the hard disk device 18 stores the index data and the music number corresponding to each music data together with all the music data constituting the album. This index data includes a disc ID uniquely assigned to the storage medium storing the album. As described above, in the album collection creation mode, for each album that satisfies a preset condition, a set of all music data, index data, and music numbers included in the album is stored in the hard disk device 18. An album collection is created.

<A-3: Operation of the present embodiment>
Next, the operation of the music playback device according to this embodiment will be described. First, when the user performs a predetermined operation on the input device 15 and gives an instruction to start the music reproduction control program, the CPU 11 transfers the music reproduction control program stored in the hard disk device 18 to the RAM 12. Run this. Hereinafter, the operation in accordance with the music reproduction control program is performed in accordance with the operation (FIGS. 4 to 9) for creating a music collection or album collection from the music data stored in the storage medium, and the created music collection or album collection. The operation will be described separately when used (FIGS. 10 to 13).

<A-3-1: Operation when creating a music book or album book>
First, when a predetermined operation is performed on the input device 15 by the user, the CPU 11 executes an operation for creating a music collection or album collection from music data stored in the CD 131 or the MD 141. FIG. 4 is a diagram showing a main routine of this operation. Here, it is assumed that the CD 131 is a playback target, but the same operation is performed when the MD 141 is a playback target.

  When the user inserts the CD 131 into the CD drive 13, the CD drive 13 outputs a signal indicating that the CD 131 has been inserted to the CPU 11. When this signal is detected (step S1), the CPU 11 performs a process for allowing the user to select an operation mode (step S2). That is, the CPU 11 first causes the display device 16 to display a screen (hereinafter referred to as “operation mode selection screen”) G1 for allowing the user to select either the music collection creation mode or the album collection creation mode. As shown in FIG. 5, the operation mode selection screen G1 includes an area A1 corresponding to the music collection creation mode and an area A2 corresponding to the album collection creation mode. The user firstly operates the pointing device of the input device 15 to move the pointer P displayed on the screen into the area A1 or the area A2, and secondly, in this state, the input device By performing a predetermined operation on 15 (for example, clicking a mouse button), it is possible to select either the music collection creation mode or the album collection creation mode.

  Next, as shown in FIG. 4, the CPU 11 determines whether or not the operation mode selected by the user is the music collection creation mode (step S3). If it is determined that the music collection creation mode has been selected, the CPU 11 executes a music collection creation process (step S4). On the other hand, when it is determined that the selected operation mode is not the music collection creation mode, that is, when the user selects the album collection creation mode, the CPU 11 executes album collection creation processing (step S5). When the music book creation process or the album book creation process ends, the CPU 11 ends the main routine.

  Next, the music collection creation process in step S4 described above will be described with reference to the flowchart shown in FIG. First, the CPU 11 displays a screen (hereinafter referred to as a “condition setting screen”) G2 for allowing the user to select a condition of music data to be stored in the hard disk device 18 among a plurality of music data stored in the CD 131. It is displayed on the display device 16 (step S401). As shown in FIG. 7, the condition setting screen G2 includes areas Aa1 to Aa4 corresponding to the first condition Ca1 to the fourth condition Ca4 described above. The user selects any one of the first condition Ca1 to the fourth condition Ca4 by performing the same operation on any one of the areas Aa1 to Aa4 as in the mode selection screen G1. However, if no condition is selected, the third condition Ca3 set as the initial value is selected.

  When this condition setting is completed, the CPU 11 instructs the CD drive 13 to read music data (step S402). Receiving this instruction, the CD drive 13 outputs to the sound output device 17 the data corresponding to the first music among the plurality of music data stored in the CD 131 and starts measuring the reproduction time of the music. The music data output from the CD drive 13 is supplied from the D / A converter 171 to the speaker 173 via the audio system 172, and the musical sound corresponding to this music data is output.

  After giving a read instruction to the CD drive 13, the CPU 11 waits until the reproduction of the music is completed (step S403). Here, the CPU 11 is not only when a certain piece of music is played to the end, but also when a user gives an instruction to end the playback during the playback of this music, or during the playback of this music. Even when the user gives an instruction to switch the reproduction target to another music piece, it is determined that the reproduction of the music piece has ended.

  When detecting the end of the reproduction of the music (step S403), the CPU 11 acquires the time elapsed from the start of the reproduction of the music to the time point from the CD drive 13, and the reproduction time satisfies the condition selected in step S401. It is determined whether or not the condition is satisfied (step S404). For example, assuming that the third condition Ca3 is selected in step S401, the CPU 11 determines that the condition is satisfied if the music playback time acquired from the CD drive 13 is 2 minutes or longer (step S404). Yes) If it is less than 2 minutes, it is determined that the condition is not satisfied (step S404; No). If it is determined that the condition is satisfied, the CPU 11 shifts the process to step S405 and executes a process for creating a music collection.

  That is, the CPU 11 first determines whether or not the music data whose end of reproduction has been detected in step S403 is already stored in the hard disk device 18 (step S405). If it is determined that the music data is not yet stored in the hard disk device 18, the CPU 11 requests the music data from the CD drive 13 and correspondingly reads the music data read from the CD 131. Obtained from the CD drive 13. Further, as shown in FIG. 2, the CPU 11 stores the acquired music data together with the index data and the reproduction history data of the music in the hard disk device 18 (step S406). At this time, of the reproduction history data stored in the hard disk device 18, the total reproduction time is the reproduction time acquired from the CD drive 13 in step S404, and the number of reproductions is “1”.

  On the other hand, if the music data is already stored in the hard disk device 18, it is not necessary to store the music data again. Therefore, in this case, the CPU 11 updates only the reproduction history data associated with the music data in the hard disk device 18 (step S407). Specifically, the CPU 11 adds the reproduction time acquired from the CD drive 13 in step S404 to the total reproduction time of the music data stored in the hard disk device 18, and increases the number of reproductions by “1”.

  On the other hand, if it is determined in step S404 that the playback time of the music does not satisfy the setting condition, the music data played this time should not constitute a music book (that is, not a user's favorite music). The CPU 11 shifts the process to step S408 without going through steps S405 to S407.

  When it is determined in step S404 that the setting condition is not satisfied, or the update of the stored contents of the hard disk device 18 in step S406 or step S407 is completed, the CPU 11 performs an operation on the input device 15 to end the music collection creation process. It is then determined whether or not the process has been performed (step S408). If it is determined that this operation has been performed, the CPU 11 ends the music collection creation process shown in FIG. On the other hand, if it is determined that the above operation is not performed, the CPU 11 shifts the processing to step S402 and instructs the CD drive 13 to reproduce the next music data. Thereafter, a series of processing from step S402 to S408 is repeated until an operation for ending the music collection creation processing is performed (step S408; Yes). As a result, the hard disk device 18 is composed of a music collection made up of a plurality of music data stored in the CD 131 that satisfies the conditions set by the user (that is, user's favorite music data). .

  Next, the album collection creating process shown in step S5 of FIG. 4 will be described in detail with reference to FIG. First, the CPU 11 causes the display device 16 to display a condition setting screen G3 for allowing the user to select conditions for storing the album stored in the CD 131 in the hard disk device 18 (step S501). As shown in FIG. 9, the condition setting screen G3 includes areas Ab1 to Ab3 corresponding to the first condition Cb1 to the third condition Cb3 described above. The user selects one of the conditions by operating the input device 15 while viewing the condition setting screen G3. However, when neither condition is selected, the second condition Cb2 set as the initial value is selected.

  When this condition setting is completed, the CPU 11 instructs the CD drive 13 to play an album (step S502). Upon receiving this instruction, the CD drive 13 sequentially reads a plurality of music data stored in the CD 131 and supplies them to the sound output device 17 and counts the number of music played to the end without being interrupted. Begin to. As a result, the music stored on the CD 131 is sequentially output from the speaker 173.

  After giving a read instruction to the CD drive 13, the CPU 11 stands by until the reproduction of the album is completed (step S503). Here, in addition to the case where the reproduction of all the music data composing the album is completed, the CPU 11 is instructed by the user to end the reproduction of the album during the reproduction of any music. In addition, it is determined that the reproduction of the album has been completed.

  When detecting the end of the reproduction of the album (step S503), the CPU 11 obtains from the CD drive 13 the number of pieces of music data that have been reproduced up to that point after outputting the reproduction instruction to the CD drive 13, and the number thereof. Determines whether the condition selected in step S501 is satisfied (step 504). For example, assuming that the second condition Cb2 is selected in step S501, the CPU 11 determines that the condition is satisfied if the number of music data reproduced to the end is five or more (step S504). Yes) If it is less than 5 songs, it is determined that the condition is not satisfied (step S504; No). If the condition is not satisfied, it is not necessary to add this album to the album book, so the album book creation process shown in FIG. 8 is terminated without performing any process.

  On the other hand, when the number of reproduced music satisfies the condition (step S504; Yes), the CPU 11 executes a process for adding this album to the album collection. That is, first, the CPU 11 determines whether or not this album is already stored in the hard disk device 18 (step S505). Here, if it is already stored, there is no need to store it again. Therefore, in this case, the CPU 11 ends the album collection creating process shown in FIG. 8 without performing any process.

  On the other hand, if it is determined in step S504 that it is not yet stored in the hard disk device 18, the CPU 11 requests the album stored in the CD 131 from the CD drive 13 and the album read from the CD 131 in response to this. Is received from the CD drive 13. Then, as shown in FIG. 3, the CPU 11 stores the album acquired from the CD drive 13 together with the index data of the CD 131 in the hard disk device 18 (step S506), and ends the album collection process.

<A-3-2: Operation when using a music collection or album collection>
Next, with reference to FIG. 10, an explanation will be given on the operation when the music book created by the music book creation process shown in FIG. 6 or the album book created by the album book creation process shown in FIG. 8 is reproduced. To do.

  First, when a predetermined operation is performed on the input device 15 by the user and an instruction to reproduce the music book or album book is given, the CPU 11 determines which of the music book or album book has been selected by the user. Determination is made (step S701). If it is determined that the music collection is selected, the CPU 11 displays the music collection list L1 shown in FIG. 11 based on the index data and the reproduction history data of each music stored in the hard disk device 18 as the music collection. (Step S702). As shown in the figure, the music collection list L1 includes, for each piece of music constituting the music collection, a disk ID of the storage medium storing the music data of the music, the music number of the music data, and the music It is a list in which the number of reproductions and the total reproduction time are associated with each other. For example, according to the music collection list L1 shown in FIG. 11, the music with the music number “Music001” was stored in the storage medium with the disk ID “Disk [A]”. It is understood that the total reproduction time is “18 minutes 26 seconds”.

  Next, the CPU 11 determines whether or not an instruction to rearrange the order of the music pieces in the music collection list L1 is given by the user (step S703). If it is determined that this instruction has been given, the CPU 11 rearranges the items (music number, disc ID, etc.) included in the music collection list based on the total playback time of each music (step S704). Specifically, instead of the music collection list L1 shown in FIG. 11, the CPU 11 displays a music collection list L1 ′ in which items related to each music are arranged in the order of the longest total reproduction time, as shown in FIG. To display. On the other hand, when determining that no rearrangement instruction has been given, the CPU 11 shifts the processing to step S705 without passing through step S704.

  Here, by operating the input device 15, the user can select any of the songs included in the song collection list as a playback target. In step S705, the CPU 11 determines whether or not this music selection has been made. If it is determined that one of the songs has been selected (step S705; Yes), the CPU 11 reads the song data of the song from the hard disk device 18 and outputs it to the sound output device 17 (step S706). As a result, the music selected by the user is output from the speaker 173. Thereafter, as in step S403 in FIG. 6, the CPU 11 waits until the music is played to the end or an instruction to stop the playback of the music is given during the playback (step S707). ). When detecting the end of the reproduction of the music piece, the CPU 11, like step S 407 shown in FIG. 6, based on the time elapsed from the start to the end of the reproduction of the music piece, (Total playback time) is updated (step S708). When the update of the reproduction history data is completed, or when it is determined in step S705 that no music is selected, the CPU 11 shifts the process to step S720.

  On the other hand, if it is determined in step S701 that the music collection list has not been selected (that is, the album collection list has been selected), the CPU 11 determines, based on the index data of each album stored as an album collection in the hard disk device 18. The album list L2 shown in FIG. 13 is displayed on the display device 16 (step S710). As shown in FIG. 13, the album collection list L2 is a list in which the disc ID of the storage medium in which each album is stored and the music number of the music constituting the album are associated with each other.

  Next, the CPU 11 determines whether any of the albums included in the album list is selected by the user (step S711). If it is determined that this selection has been made, the CPU 11 sequentially reads out each piece of music data constituting the selected album from the hard disk device 18 and outputs it to the sound output device 17 (step S712). Then, when the reproduction of the album is finished (step S713), or when it is determined that the album is not selected in step S711 (step S711; No), the CPU 11 shifts the processing to step S720.

  In step S720, the CPU 11 determines whether or not an operation for ending the reproduction process has been performed by the user. If it is determined here that an end instruction has been given, the CPU 11 ends the reproduction process shown in FIG. On the other hand, when determining that the end instruction is not given, the CPU 11 shifts the processing to step S701 and repeats the above-described operation.

  As described above, in the music collection creation mode in the present embodiment, music data stored in the storage medium that has been played for a predetermined time is stored in the hard disk device 18. . A general user plays a favorite piece of music for a long time, while interrupting a piece of music that he does not like in a short time. Therefore, according to the present embodiment, it is possible to obtain a music collection including user's favorite music without requiring an operation of selecting a favorite music every time each music is played.

  Further, in the album collection creation mode in the present embodiment, the album stored in the storage medium is stored in the hard disk device 18 when the number of reproduced songs exceeds a predetermined number. A general user likes an album that contains more favorite music data. Therefore, it is possible to obtain an album collection composed of albums that meet the user's preference without requiring an operation of selecting whether or not the album is a favorite one each time the album is reproduced. Thus, according to the present embodiment, it is possible to reduce the burden of the user selecting a song or album that suits his / her preference. In the present embodiment, since the user can select the conditions of the music that should constitute the music collection and the conditions of the album that should constitute the album collection, the user's preference is more reflected. You can create music collections and album collections.

  Further, in the present embodiment, music data stored in a storage medium such as a CD 131 or MD 141 is transferred to the hard disk device 18. Here, the access speed to the hard disk device 18 is generally faster than the access speed to the CD 131, MD 141, or the like. Therefore, according to the present embodiment, there is an advantage that it is possible to shorten the time until the user's favorite music is played.

  Moreover, in this embodiment, since the order of the music included in the music collection list L1 can be rearranged according to the total playback time, the music that the user particularly likes among the music included in the music collection can be easily selected. can do. In the above embodiment, the music is rearranged according to the total reproduction time. However, the same effect can be obtained even if the music is rearranged according to the number of times of reproduction.

<B: Second Embodiment>
Next, a second embodiment of the present invention will be described. The configuration of the music reproducing device according to the present embodiment is the same as the configuration shown in FIG.

  In the above embodiment, as shown in FIG. 11, only the information about the music data already stored in the hard disk device 18 among the music data stored in the storage medium is included in the music collection list L1. did. On the other hand, in this embodiment, information about music data not yet stored in the hard disk device 18 is also included in the music collection list. The operation of this embodiment is the same as that of the first embodiment shown in FIGS. 4, 6, 8 and 10 except for a part. Therefore, in the following, operations different from those of the first embodiment will be mainly described, and descriptions of common operations will be omitted as appropriate.

  First, when a storage medium is inserted as a playback target, the CPU 11 causes the hard disk device 18 to store information for identifying all music data stored in the storage medium. Specifically, when the insertion of the storage medium is detected in step S1 shown in FIG. 4, the CPU 11 stores the disk ID of the storage medium and the storage ID stored in the storage medium based on the TOC information stored in the storage medium. The music numbers of all the music are stored in the hard disk device 18. The contents of the music collection creation operation (FIG. 6) and the album collection creation operation (FIG. 8) are the same as those in the first embodiment.

  Next, with reference to FIG. 14, an operation when a music book or album book is reproduced will be described. 14 differs from the operation shown in FIG. 10 in the music collection list display operation executed in step S702 and the operation after the music is selected in step S705.

  First, when a music collection is selected in step S701, the CPU 11 displays a music collection list L3 on the display device 16 (step S702). As shown in FIG. 15, this music collection list L3 includes, for each storage medium reproduced in the past, the disk ID of the storage medium, the music numbers of all the music data stored in the storage medium, and each music It includes the number of past data playbacks and total playback time.

  However, among the songs included in the music collection list L3, the music whose music data is stored in the hard disk device 18 in step S406 shown in FIG. 6 is the music that has not yet been stored in the hard disk device 18. Are displayed in different ways. For example, in FIG. 15, music data corresponding to “Music001” and “Music003” among the storage media whose disk ID is “Disk [A]” is already stored in the hard disk device 18, while “Music002”, It is assumed that music data corresponding to “Music 004” and “Music 005” has not yet been stored in the hard disk device 18. Therefore, in this music collection list L3, “Music001” and “Music003” are displayed in standard characters, whereas “Music002”, “Music004” and “Music005” are italic and bold. It is displayed.

  On the other hand, when any one of the songs included in the music collection list L3 is selected by the user (step S705), the CPU 11 determines whether or not the music data of the selected music is already stored in the hard disk device 18. Is determined (step S730). If it is determined that the data has already been stored, the CPU 11 shifts the processing to step S706 and executes the operations after step S706 described in the first embodiment.

  On the other hand, when determining that the music data is not yet stored in the hard disk device 18, the CPU 11 displays on the display device 16 that the storage medium storing the music data should be inserted (step S731). For example, when “Music002” of “Disk [A]” is selected in the music collection list L3 shown in FIG. 15, “This music data is not stored on the hard disk. Disk [A] is set. Please read "is displayed.

  When the user inserts a storage medium in response to the notification, the CPU 11 acquires the music data selected in step S705 from the music data stored in the storage medium from the CD drive 13 and displays the music data. 2 is stored in the hard disk device 18 (step S732), and the process proceeds to step S720. As a result, in the music collection list L3 displayed in the next step S702, the music number of the music data newly stored in the hard disk device 18 in step S732 is a standard character (that is, italic or bold). Is not displayed). And if it selects in step S705, this music data will be reproduced | regenerated by the process after step S706.

  As described above, the present embodiment can provide the same effects as those of the first embodiment. Further, in the present embodiment, when music data not stored in the hard disk device 18 is selected, a storage medium including the music data is notified to the user. Therefore, a user who wants to play music that is not included in the music collection can easily grasp the storage medium in which the music is stored. Furthermore, music that was not added to the music collection because the set condition was not satisfied can be added to the music collection as appropriate according to the user's selection.

  In the music collection list L3 shown in FIG. 15, information related to music data stored in the hard disk device 18 is displayed in standard characters, while information related to music data not stored is displayed in italics and bold. However, the display mode is not limited to this. For example, each piece of information may be displayed with different colors, may be displayed with different sizes, or may be displayed with different fonts. In short, it is only necessary for the display mode to be different so that the user who visually recognizes the display can distinguish both pieces of information.

  In this embodiment, the storage medium to be inserted is displayed as a character (image). However, a sound indicating the storage medium may be output. That is, it is only necessary to notify the user of information for specifying a storage medium in which music data not yet stored in the hard disk device 18 is stored.

<C: Third Embodiment>
Next, a third embodiment of the present invention will be described. In the present embodiment, when the music data stored in the storage medium is reproduced, the music data is stored in the hard disk device 18, while when the period or time zone is designated by the user, the period or time Music data reproduced at a past time point included in the band is extracted. The details are as follows. The configuration of the music reproducing device according to the present embodiment is the same as the configuration shown in FIG.

  First, when the user inserts the CD 131 and is instructed to reproduce any music data, the CD drive 13 reads out the instructed music data from the CD 131 and starts outputting it to the sound output device 17. At this time, the CD drive 13 notifies the CPU 11 of the date and time when the reproduction is started, the disk ID of the storage medium, and the music number of the music data designated as the reproduction target. When the reproduction of the music data is completed, the CPU 11 acquires the music data from the CD drive 13 and, as shown in FIG. 16, the music data and the reproduction history data indicating the reproduction start date and time notified earlier. The hard disk device 18 stores a set of index data including the disk ID and the music number. Further, when music data already stored in the hard disk device 18 is reproduced, the reproduction date and time is added to the reproduction history data.

  Next, when a predetermined operation is performed on the input device 15 by the user, the CPU 11 executes a process for reproducing the music data stored in the hard disk device 18. FIG. 17 is a flowchart showing the contents of this operation. As shown in the figure, the CPU 11 first displays a screen (hereinafter referred to as “extraction condition setting screen”) for allowing the user to input the conditions of the music data to be reproduced among the music data stored in the hard disk device 18. G4 is displayed on the display device 16 (step S801). As shown in FIG. 18, the extraction condition setting screen G4 includes input areas Ac1 and Ac2 for designating the start and end of the period, and input areas Ac3 and Ac4 for designating the start and end of the time period, respectively. Including. The user operates a pointing device and a keyboard of the input device 15 to input desired numerical values in the input areas Ac1 to Ac4. The user may input numerical values in all of the input areas Ac1 to Ac4, or input numerical values only to one of the input areas Ac1 and Ac2 related to the period, or the input areas Ac3 and Ac4 related to the time zone. You may enter.

  When the input is completed, the CPU 11 stores the music data stored in the hard disk device 18 at the time indicated by the reproduction history data associated with the music data in the input period or time zone. Search is performed (step S802). Next, the CPU 11 displays the music list L4 on the display device 16 based on the extraction result (step S803). As shown in FIG. 19, the song list L4 includes the song number of the song data searched in step S803, the disk ID of the storage medium in which the song data is stored, the playback date and the playback time. It is out.

  For example, when “7/1 (July 1)” is input to the input area Ac1 and “8/31 (August 31)” is input to the input area Ac2 in step S801, the CPU 11 In step S802, music data whose reproduction date indicated by the reproduction history data is any date from July 1 to August 31 is extracted. In this case, the music list L4 displayed in step S803 includes information related to the music data reproduced during the period from July 1 to August 31 as shown in FIG. Although the case where the period is input is illustrated here, the same processing is performed when the time zone is specified or when both the period and the time zone are input.

  On the other hand, the CPU 11 determines whether any of the songs included in the song list L4 has been selected by the user (step S804). If it is determined that the song has been selected, the CPU 11 reads the song data of the song from the hard disk device 18 and outputs it to the sound output device 17 (step S805). As a result, a musical tone is output based on the selected music data. Further, the CPU 11 adds the date and time when the current reproduction was started to the reproduction history data associated with the music data reproduced here (step S806), and the process proceeds to step S807. On the other hand, if it is determined in step S804 that no music has been selected, the CPU 11 shifts the process to step S807 without passing through steps S805 and S806. Thereafter, the processing from step S801 to step S806 is repeated until an operation for instructing termination is performed by the user (step S807; Yes).

  As described above, according to the present embodiment, music data is extracted according to a specified period, so that music that has been played in any period or time zone in the past can be easily obtained. Can be selected. For example, if a period corresponding to summer (for example, from July to August) is input in step S801, songs that have been heard in the past summer are displayed in the song list L4, which corresponds to the morning of the day. If a time zone (for example, 6 am to 8 am) is input, songs that have been listened to in the past morning are displayed in the song list L4, and so on. It becomes possible to select easily.

<D: Modification>
Although one embodiment of the present invention has been described above, the above embodiment is merely an example, and various modifications can be made to the above embodiment without departing from the spirit of the present invention. As modifications, for example, the following can be considered.

That is, according to the total reproduction time of each music data, the character of the information regarding each music data may be enlarged, and the color and brightness of the character may be varied. For example, for music data with the longest total playback time, information related to this is displayed in large characters, while this information is displayed in small characters as the total playback time becomes shorter. Moreover, you may display the bar graph of the length according to the total reproduction time for every music.

<D-2: Modification 2>
In an environment where a plurality of users use the music playback device, the music collection and album collection shown in the first embodiment may be created for each user. That is, a different identification number is assigned to each of a plurality of users, and the above-described music collection or album collection is created for each identification number. The details are as follows.

  First, for example, prior to step S2 shown in FIG. 4, the user identification number is input. In step S406 shown in FIG. 6, the input identification number is associated with the music data, the index data, and the reproduction history data (see FIG. 2) and stored in the hard disk device 18. Similarly, in step S8 shown in FIG. 8, the input identification number is associated with the album and index data (see FIG. 3) and stored in the hard disk device 18. Thereby, a music collection and an album collection are created for each user.

  On the other hand, prior to step S701 shown in FIG. 10, the user identification number is input. Then, when the music collection list is displayed in step S702 shown in FIG. 10 or the album collection list is displayed in step S710, only the music collection or album collection associated with the input identification number is displayed in FIG. Or a list is displayed as shown in FIG. Alternatively, as shown in FIG. 20, the identification numbers of all users may be displayed in association with the list display of the music collection or album collection created for the user. That is, FIG. 20 shows a case where a music collection created for a user whose identification number is “ID01” and a music collection created for a user whose identification number is “ID02” are displayed in a list. Has been.

  Even under this configuration, the same effect as in the first embodiment can be obtained. In addition, according to this modification, even when a plurality of users use one music playback device, a music book or album book that suits each user's preference can be created. When there is music data to be stored in common for a plurality of users, the music data is not stored for each user, but only one music data is stored in the hard disk device 18. Also good. In this way, the storage area of the hard disk device 18 can be used efficiently. Further, the idea according to this modification may be applied to the second and third embodiments.

<D-3: Modification 3>
In the music collection creation mode of the first embodiment, the music data to be stored in the hard disk device 18 is selected according to the playback time. However, the condition for selecting the data to be stored in the hard disk device 18 is as follows. It is not limited to. That is, for example, among a plurality of music data stored in the storage medium, music data in which the cumulative number of reproductions in the past exceeds a predetermined number may be stored in the hard disk device 18. In this case, the number of reproductions is also counted for music data that has not yet been stored in the hard disk device 18, and music data whose cumulative number of reproductions has exceeded a predetermined value due to reproduction at a certain time is stored in the hard disk device 18. You can make it. Alternatively, the music data whose accumulated time (total playback time) played in the past exceeds a predetermined time may be stored in the hard disk device 18. However, in the present invention, the condition to be stored in the storage means (hard disk device 18) is not limited to the output time or the number of outputs. In short, it is only necessary that music data in which the output status to the sound output device satisfies a predetermined condition is selectively stored in the hard disk device 18.

  In the first and second embodiments, a plurality of conditions are prepared in advance for the music data (or album) to be stored in the hard disk device 18, and the user selects one of these conditions. However, the user may arbitrarily select this condition. For example, in step S401 shown in FIG. 6, the playback time that is a condition for storing music data in the hard disk device 18 may be input as a numerical value. Similarly, in step S501 shown in FIG. 8, the number of reproduced music pieces that are conditions for storing the album in the hard disk device 18 may be input as a numerical value. On the other hand, a configuration in which the user can specify these conditions is not always necessary. That is, for example, only one condition may be fixed in advance.

<D-4: Modification 4>
In the first and second embodiments, the music data is transferred from the storage medium to the hard disk device 18 after the reproduction of the music data from the storage medium is completed. However, the music data may be transferred to the hard disk device 18 in parallel with the reproduction of the music data from the storage medium.

  For example, focusing on the music collection creation mode of the first embodiment, every time a part of music data is read from the storage medium and output to the sound output device 17, the CPU 11 stores the music data in the hard disk device 18. May be temporarily stored in a predetermined storage area (hereinafter referred to as “temporary storage area”). When the reproduction of the music is finished, it is determined whether or not the reproduction time satisfies a predetermined condition. If the reproduction time is satisfied, the music data stored in the temporary storage area is stored in the memory where the music collection is to be stored. Transfer to region. On the other hand, when the predetermined condition is not satisfied, the CPU 11 discards the music data stored in the temporary storage area. Even under this configuration, the same effect as in the first embodiment can be obtained. In addition, although it demonstrated paying attention to music collection creation mode here, the same structure can be employ | adopted also about album collection creation mode.

<D-5: Modification 5>
In the first and second embodiments, the music data satisfying the predetermined condition for the reproduction time or the number of music to be reproduced is stored in the hard disk device 18 over the whole music, but a part of one music Only the music data corresponding to may be stored in the hard disk device 18. For example, in the music collection creation mode of the first embodiment, when the second condition Ca2 or the third condition Ca3 is selected, that is, it is set as a condition that the music data has been played over a certain period of time. Assuming that this condition is satisfied and the reproduction of the music data is terminated, among the music data corresponding to one music, the music data reproduced so far (that is, one music May be stored in the hard disk device 18.

<D-6: Modification 6>
In each of the above embodiments, music data (or an album made up of a plurality of music data) is stored in the hard disk device 18, but a storage medium in which image data representing an image is stored together with music data is a processing target. In this case, image data may be stored in the hard disk device 18 together with the music data. Then, when the music data is read from the hard disk device 18, the image data may be output to the display device 16 in parallel.

<D-7: Modification 7>
Data conforming to the MIDI (Musical Instrument Digital Interface) standard is stored in a floppy (registered trademark) disk or the like, and a musical sound (ie, accompaniment sound) corresponding to the MIDI data is reproduced in parallel with the reproduction of the music from the CD 131 or MD 141. ) May be output. In such a case, when the music data stored in the CD 131 or the MD 141 is stored in the hard disk device 18, this MIDI data may also be stored in association therewith. Then, when the music data stored in the hard disk device 18 is reproduced, the MIDI data may be output to a sound source to output a musical sound. In this way, it is possible to output more diverse musical sounds than when only the storage medium such as the CD 131 or the MD 141 is used.
