  According to the present invention, a desired folder can be accurately accessed from a plurality of folders having a complicated hierarchical structure by referring to the registered identification information.

  The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

  Referring to FIG. 1, IC recorder 10 of this embodiment includes a key input device 20. When a power-on operation is performed by the key input device 20, power based on a battery (not shown) is supplied to the entire system. As a result, the IC recorder 10 is activated.

  A microphone 22 and an audio player 24 are alternatively connected to the audio input terminal 26. A PC (Personal Computer) 42 is connected to the USB controller 40. Further, in the memory card 12, an MIC folder, a LINE folder, and a MUSIC folder are formed as shown in FIG. Note that the microphone 22, the audio player 24, the PC 42, and the memory card 12 are all connected to or attached to the IC recorder 10 as necessary.

  When the REC key 20a on the key input device 20 is operated in a state where the microphone 22 is connected to the audio input terminal 26 and the microphone input mode is selected, the MCU 14 stores a folder in the lower hierarchy of the MIC folder shown in FIG. Is newly created, or one of the created folders is designated in the lower hierarchy of the MIC folder. The MCU 14 further issues an encoding instruction and a compression instruction to the codec 30 and the DSP 18, respectively.

  The codec 30 encodes the audio signal captured by the microphone 22 and amplified by the amplifier 26 into digital audio data, and provides the encoded audio data to the MCU 14 through the bus BS1. The MCU 14 provides the given audio data to the DSP 18 through the memory 16.

  The DSP 18 compresses the given audio data and stores the compressed audio data in the memory 16. The MCU 14 records the compressed audio data stored in the memory 16 in the flash memory 12 in a file format. A file created under the microphone input mode, that is, a microphone file, is stored in a folder newly created in the lower hierarchy of the MIC folder or a folder designated in the lower hierarchy of the MIC folder.

  The MCU 14 further instructs the LCD driver 36 to output mode information indicating the “microphone input mode”, and displays this mode information on the LCD monitor 38. Thus, the processing operation according to the microphone input mode is realized. The activated microphone input mode is stopped when the STOP key 20b on the key input device 20 is operated.

  When the REC key 20a on the key input device 20 is operated in a state where the audio player 24 is connected to the audio input terminal 26 and the line input mode is selected, the MCU 14 moves to the lower level of the LINE folder shown in FIG. A new folder is created, or one of the created folders is specified below the LINE folder. The MCU 14 further issues an encoding instruction and a compression instruction to the codec 30 and the DSP 18, respectively.

  The codec 30 and the DSP 18 execute the same processing as described above, and thereby compressed audio data is stored in the memory 16. The MCU 14 records the compressed audio data stored in the memory 16 in the flash memory 12 in a file format. A file created under the line input mode, that is, a line file is stored in a folder newly created below the LINE folder or a folder designated below the LINE folder.

  The MCU 14 further instructs the LCD driver 36 to output mode information indicating the “line input mode”, and displays this mode information on the LCD monitor 38. Thus, the processing operation according to the line input mode is realized. The activated line input mode is stopped in response to the operation of the STOP key 20b.

  When the PC 42 is connected to the USB controller 40 and a file transfer operation is performed on the PC 42, a desired audio file is transferred from the PC 42 to the USB controller 40 under the file transfer mode. The MCU 14 stores the transferred audio file in a folder newly created in the lower layer of the MUSIC folder shown in FIG. 2 or a folder designated in the lower layer of the MUSIC folder. Thereby, for example, a hierarchical structure as shown in FIG. 3 is constructed under the MUSIC folder.

  According to FIG. 3, folder 01, folder 04 and folder 06 are stored in the MUSIC folder (see hierarchy L1). The folder 01 stores files 01 to 03 and the folder 02, the folder 04 stores folder 05, and the folder 06 stores files 10 to 12 (see the hierarchy L2). In addition, file 04 to file 05 and folder 03 are stored in folder 02, and file 08 to file 09 are stored in folder 05 (see hierarchy L3). Further, file 06 to file 07 are stored in the folder 03.

  In the state where the microphone input mode, the line input mode, and the file transfer mode are stopped, one of a plurality of folders formed on the memory card 12 is designated by a folder designation operation on the key input device 20, and further designated. One of the plurality of files under the selected folder is selected by a file selection operation on the key input device 20.

  When the OK key 20e on the key input device 20 is operated in a state where a desired file is selected, the MCU 14 issues a decompression instruction and a decoding instruction to the DSP 18 and the codec 30, respectively, and the desired file is transmitted to the bus BS1. Read through. The read file is given to the DSP 18 through the memory 16.

  The DSP 18 decompresses the compressed audio data included in the given file and stores the decompressed audio data in the memory 16. The MCU 14 provides the audio data stored in the memory 16 to the codec 30 through the bus BS1. The codec 30 decodes the given audio data into an analog audio signal, and outputs the decoded audio signal from the speaker 34 through the amplifier 32. The MCU 14 further instructs the LCD controller 36 to output file identification information for identifying the file currently being reproduced, and displays the file identification information on the LCD monitor 38.

  When the + key 20c on the key input device 20 is operated during such file reproduction processing, the MCU 14 increases the reproduction speed of the audio data. Further, when the -key 20d on the key input device 20 is operated during the file playback process, the MCU 14 decreases the playback speed of the audio data. Further, when the reproduction of the currently selected file is completed, the MCU 14 executes a file reproduction process focusing on the next file. Furthermore, when the STOP key 20b on the key input device 20 is operated during the file playback process, the MCU 14 stops the playback of the audio data.

  When the folder specified by the folder specifying operation is a folder under the MUSIC folder, the folder skip process is performed in response to the operation of the + key 20c and the − key 20d in the state where the file reproduction process is stopped. Is executed.

  However, in order to support the folder skip processing, the folder table 14t shown in FIG. 4 is created corresponding to the hierarchical structure shown in FIG. 3 when the power is turned on. According to FIG. 4, folder 01 is registered in the first column, and folder 02 is registered in the second column. Also, the folder 05 is registered in the third column, and the folder 06 is registered in the fourth column. Each registered folder is a folder for storing at least one file.

  In the folder skip process, the folder of interest on the folder table 14t is updated as shown in FIG. 5 in response to the operation of the + key 20c or the − key 20d. That is, each time the + key 20c is operated, the folder of interest is cyclically updated in the forward direction in the manner of folder 01 → folder 02 → folder 05 → folder 06 → folder 01 →. The focused folder is also cyclically updated in the reverse direction in the order of folder 06 → folder 05 → folder 02 → folder 01 → folder 06 →... Every time the −key 20d is operated.

  When the OK key 20c is operated after such folder skip processing, playback of the first file stored in the folder of interest is started. As a result, the operability when reproducing a file managed by the MUSIC folder is improved.

  The folder table 14t is created as follows. First, a variable T for designating a column on the folder table 14t is set to “1”, and a MUSIC folder is set as a reference folder. Further, the total number of folders stored in the reference folder is set to the variable Mmax, and the variable M is set to “1”. In the hierarchical structure shown in FIG. 3, the variable Mmax is set to “3”.

  Next, a file search process for searching for a file from the Mth folder stored in the reference folder is executed. When at least one file is found by the file search process, folder identification information for identifying the Mth folder is described in the Tth column of the folder table 14t. The variable T is incremented after the folder identification information is described. When no file is found in the Mth folder or when the registration process of the Mth folder accompanying the discovery of the file is completed, the variable M is incremented within a range equal to or less than the variable Mmax, and corresponds to the incremented variable M. A file search process is executed.

  If the reference folder is a MUSIC folder, a folder search process for searching for another folder from the Mth folder is additionally executed. If at least one folder is found by the folder search process, the variables M and Mmax and the folder identification information for identifying the reference folder are saved. Specifically, the variable M is stored in the variable N, the variable M is stored in the variable Mmax, and folder identification information for identifying the reference folder is stored in the folder information FLD.

  Thereafter, the Mth folder is set as the reference folder, the total number of folders stored in the Mth folder is set in the variable Mmax, and the variable M is returned to “1”. The file search process described above is repeatedly executed until the variable M reaches the variable Mmax. Since a folder different from the MUSIC folder is set as the reference folder, the folder search process is omitted or prohibited.

  When the variable M reaches the variable Mmax, it is determined whether or not the reference folder is a MUSIC folder. If the reference folder is a MUSIC folder, the folder table 14t creation process is terminated. On the other hand, if the reference folder is a folder different from the MUSIC folder, the saved variables N and Nmax and the folder information FLD are restored or restored. That is, the variable N is reset to the variable M, the variable Nmax is reset to the variable Mmax, and the folder indicated by the folder information FLD, that is, the MUSIC folder is reset as the reference folder. The file search process and folder search process described above are resumed after such a return process.

  As a result of the above processing being executed on the hierarchical structure shown in FIG. 3, a folder for storing at least one file is registered in the folder table 14t. That is, the folder 01 of the hierarchy L1 is registered first, and then the folder 02 of the hierarchy L2 is registered. Subsequently, the folder 05 of the hierarchy L2 is registered, and then the folder 06 of the hierarchy L1 is registered.

  As described above, the folder search process is executed only when the reference folder is a MUSIC folder. Therefore, the folder to be noticed for the file search process is limited to the folders in the layers L1 and L2, and the folder 03 in the layer L3 is excluded from registration targets in the folder table 14t.

  The MCU 14 executes a plurality of tasks including the music reproduction task shown in FIGS. 6 to 10 in parallel. Control programs corresponding to these tasks are stored in the built-in flash memory 14f.

  Referring to FIG. 6, a table creation process is executed in step S1. Thereby, the folder table 14t shown in FIG. 4 is completed. In step S3, the variable T is set to “1”. In step S5, the folder identification information registered in the T-th column of the folder table 14t is read, the folder corresponding to the read folder identification information is specified from the memory card 12, and the top of the specified folder is identified. Specify an audio file. In step S7, file identification information for identifying the designated audio file is displayed on the LCD monitor 38 through the LCD driver 36.

  In step S9, it is determined whether or not the OK key 20e on the key input device 20 has been operated. In step S11, it is determined whether or not the + key 20c on the key input device 20 has been operated. In step S13, key input is performed. It is determined whether or not the -key 20d on the device 20 has been operated. If “YES” in the step S11, the variable T is incremented in a step S15, and thereafter, the process returns to the step S5. If “YES” in the step S13, the variable T is decremented in a step S17, and thereafter, the process returns to the step S5.

  If “YES” in the step S9, the process proceeds to a step S21, and the reproduction process of the audio file designated in the step S5 is started. As a result, the corresponding sound is output from the speaker 34. In step S23, it is determined whether or not the + key 20c has been operated. In step S25, it is determined whether or not the-key 20d has been operated. If YES in step S23, the audio playback speed is increased in step S27, and if YES in step S25, the audio playback speed is decreased in step S29. When the process of step S27 or S29 is completed, the process returns to step S23.

  If both steps S23 and S25 are NO, it is determined in step S31 whether or not the reproduction process started in step S21 is completed, and whether or not the STOP key 20b on the key input device 20 is operated is determined in step S31. The determination is made at S33. If “YES” in the step S31, the next audio file stored in the currently focused folder (the folder registered in the Tth column of the folder table 14t) is designated in the step S35. In step S37, file identification information for identifying the designated audio file is displayed on the LCD monitor 38 through the LCD driver 36. When the process of step S37 is completed, the process returns to step S21. As a result, the reproduction process of the next audio file is started.

  If “YES” in the step S33, the process proceeds to a step S41, and the reproduction process started in the step S21 is stopped. When the process of step S41 is completed, the process returns to step S9.

  The table creation process in step S1 shown in FIG. 6 is executed according to a subroutine shown in FIGS.

  Referring to FIG. 8, variable T is set to “1” in step S41, and the MUSIC folder is set as a reference folder in step S43. In step S45, the total number of folders stored in the reference folder is set to the variable Mmax. In step S47, the variable M is set to “1”.

  In step S49, a file is searched from the Mth folder stored in the reference folder. In step S51, it is determined whether or not at least one file has been found by the file search process in step S49. If no file is found, the process proceeds to step S57. On the other hand, if at least one file is found, the process proceeds to step S53, and folder identification information for identifying the Mth folder is registered in the Tth column of the folder table 14t. When the registration process is completed, the variable T is incremented in step S55, and then the process proceeds to step S57.

  In step S57, it is determined whether or not the reference folder is a MUSIC folder. If NO, the process proceeds to step S71. If YES, the process proceeds to step S59. In step S59, another folder is searched from the Mth folder stored in the reference folder. In step S61, it is determined whether or not at least one folder has been found by the folder search process in step S59. If “NO” here, the process proceeds to a step S71 while if “YES”, the process proceeds to a step S63.

  In step S63, the variables M and Mmax and the file identification information for identifying the reference folder are saved. Specifically, the variable M is stored in the variable N, the variable Mmax is stored in the variable Nmax, and the folder identification information for identifying the reference folder is stored in the folder information FLD.

  In step S65, the Mth folder noticed in step S59 is set as the reference folder. When the setting is completed, processing similar to the processing in steps S45 and S47 described above is executed in steps S67 and S69, and thereafter, the process returns to step S49.

  In step S71, it is determined whether or not the variable M has reached the variable Mmax. In step S75, it is determined whether or not the reference folder is a MUSIC folder. If “NO” in the step S71, the variable M is incremented in a step S73, and then the process returns to the step S49. If YES in both steps S71 and S75, the process returns to the upper hierarchy routine.

  If “YES” in the step S71 and “NO” in the step S75, the process proceeds to a step S77, and the variables M and Mmax and the file identification information saved in the step S63 are restored or restored. Specifically, the variable N is set to the variable M, the variable Nmax is set to the variable Mmax, and the folder specified by the folder information FLD, that is, the MUSIC folder is set as the reference folder. When the process of step S77 is completed, the process returns to step S57.

  As can be seen from the above description, the MCU 14 designates each of one or more folders stored in the reference folder as a target folder in a predetermined order (S45 to S47, S71 to S73). When there is another folder stored in the target folder, the MCU 14 stores the reference folder setting state (reference folder = MUSIC folder) and the target folder designation state (target folder = Mth folder) (S59). ~ S63). The MCU 14 changes the reference folder to the target folder in association with such saving processing (S65). The MCU 14 further restores the setting state of the reference folder and the specified state of the target folder with reference to the state stored by the above-described storage process after the processing for specifying the target folder corresponding to the changed reference folder is completed. (S77). The MCU 14 also registers file identification information for identifying the folder of interest in the folder table 14t when there is a file stored in the folder of interest (S49 to S53).

  Therefore, when the folder A for storing the folders a1 and a2 and the folder B for storing the folders b1 and b2 exist in the same hierarchy, the MCU 14 designates each folder in the order of A → a1 → a2 → B → b1 → b2. The identification information of the folder for storing the file in the designated folder is registered in the folder table 14t. By referring to the registered identification information in this way, a desired folder can be accurately accessed from a plurality of folders having a complicated hierarchical structure.

  In this embodiment, the table creation process shown in FIGS. 8 to 10 is executed for a folder having a hierarchical structure under the MUSIC folder. However, the table creation process is performed under the MIC folder or the LINE folder. You may make it perform with respect to the folder which has a hierarchical structure.

  In this embodiment, when the folder skip process is executed, the top file stored in the skip destination folder is played back. However, instead of the top file, the default file such as the end file is played back. You may make it do.

  Further, in this embodiment, an IC recorder is assumed as a file management apparatus, but the present invention can be applied to other apparatuses such as a digital camera as long as a plurality of files or folders are managed in a hierarchical structure. .

  In this embodiment, it is not assumed that the file is stored in the hierarchy L1 one level below the MUSIC folder (see FIG. 3), but the file may be stored in the hierarchy L1. In this case, preferably, an upper folder for storing the MIC folder, the LINE folder, and the MUSIC folder is formed in the memory card 12, and this folder is set as a reference folder in step S43 shown in FIG.
