DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing a configuration of a digital recorder to which the recording / reproducing apparatus of the present invention is applied.
The digital recorder of the present embodiment has a calendar function,
It has a function of managing voice data as a message for each date.

In FIG. 1, a microphone 1 includes an amplifier (AM).
P) 2, a low-pass filter (LPF) 3, and an A / D converter (A / D) 4 are connected to a digital signal processing unit 9. The speaker 8 includes an amplifier (AMP) 7, a low-pass filter (LPF) 6, a D / A converter (D / A)
5 is connected to the digital signal processing unit 9.

The digital signal processing unit 9 includes the system control unit 1
Connected to 0. A recording medium 11 and a drive circuit 12 for driving a display 13 are connected to the system control unit 10. Further, various operation buttons (REC, PLAY, STOP, +,-, ERA
SE) is connected. REC is record button, PLA
Y is a play button, STOP is a stop button, and ERASE is an erase button (erase selection means). The "+" and "-" buttons are used to increase or decrease the date when the schedule is input, or to increase or decrease the file number to be reproduced.

Here, the system control unit 10 is capable of continuously reproducing a plurality of audio files, and stops the reproduction of the currently reproduced audio file selected to be erased by operating the erase button ERASE. Then, it has a function as a data moving means for moving to the next audio file and automatically starting playback, and a function as an erasing means for erasing the selected audio files at once. And

In the above configuration, at the time of recording, after audio is input from the microphone 1 and amplified by the amplifier 2,
High frequency components are removed by the low pass filter 3. Then A
After being converted into a digital signal by the / D converter 4, the digital signal is subjected to compression processing by the digital signal processing unit 9 and recorded on the recording medium 11 under the control of the system control unit 10.

At the time of reproduction, audio data recorded on the recording medium 11 is read out under the control of the system control unit 10 and sent to the digital signal processing unit 9.
The digital signal processing section 9 subjects the audio data to a decompression process, and the D / A converter 5 converts the audio data into an analog signal. Then, after the high-frequency component is removed by the low-pass filter 6, the signal is amplified by the amplifier 7 and output from the speaker 8.

FIG. 2 is a flowchart for explaining the overall operation of the digital recorder. First, after performing initial settings in step S1, the process waits until an operation button is pressed by a user, and performs processing corresponding to the pressed button.
That is, it is determined in step S2 whether or not the recording button REC has been pressed.
Return to If the determination in step S2 is NO, it is determined in step S3 whether the play button PLAY has been pressed. If this determination is YES, the process shifts to the playback mode of step S6 to perform playback processing, and then returns to step S2. If the determination in step S3 is NO, it is determined in step S5 whether the erase button ERASE has been pressed. If this determination is YES, the flow advances to step S7 to delete the file specified by the user, and returns to step S2. Step S5
If the determination is NO, step S is executed without performing any processing.
Return to 2.

FIG. 3 is a flowchart for explaining the details of the processing in the above-described reproduction mode (step S6 in FIG. 2). First, in step S20, after the reproduction operation of the audio file selected by the user is started, the next step S21
To determine whether the stop button STOP has been pressed.
In the case of O, the process proceeds to step S22, and it is determined whether or not it is the file end. If the end of the file has been reached, the process proceeds to step S23 to check whether the file is the final file.
In the case of O, the process proceeds to step S24 to set the file number to 1
After that, the playback of the next audio file is started.

If the determination in step S22 is NO or after execution of step S24, the flow advances to step S25 to determine whether the erase button ERASE has been pressed. In the case of YES here, the process proceeds to step S26 to stop the reproduction of the currently reproduced audio file, and then sets the currently reproduced audio file as a deletion target (temporary deletion state), and sets the file number of the target file to the system number. Temporarily store in the internal storage area (RAM) of the control unit (step S2)
7). Next, the process proceeds to step S28 to determine whether or not the file is the last file. If YES, the process proceeds to step S34. If NO, the file number is incremented by 1 and the reproduction of the next audio file is started (step S29). Then, the process returns to step S21.

If the determination in step S25 is NO, the process proceeds to step S30 to determine whether the "+" button has been pressed. If the determination is YES, step S29 is executed and the process returns to step S21. If the determination is NO, the process proceeds to step S31 to determine whether the "-" button is pressed. Return to

On the other hand, if the judgment in step S21 is YES, or if the reproduction up to the last file is completed and the judgment in step S23 is YES, step S3
After the reproduction of the audio file is stopped in step S8, step S3
The process proceeds to step 3 to determine whether or not there is a file to be deleted. If the determination is NO, the process returns. If the determination is YES, the process proceeds to step S34. In this step S34 and the next step S35, a key input from the user is waited for 4 seconds, and if there is no key input within 4 seconds, the process returns. If there is a key input within 4 seconds, the process proceeds to step S36, and the operated key is the delete button E
It is determined whether it is RASE, and if NO, the process returns. If YES, the process advances to step S37 to delete the file to be deleted and returns.

During the execution of steps S34 and S35, the display unit 13 displays the total number of audio files to be erased (FIG. 4A) and a confirmation display as to whether or not the erase operation can be executed (FIG. 4A). 4 (B)) are performed alternately.

As described above, in the present embodiment, if the user decides that the audio file is unnecessary (should be deleted) after playing the audio file, the reproduction of the audio file is stopped and the temporary After the erased state, the reproduction of the next audio file is continuously performed. Then, after the reproduction of all the audio files is completed, the erasure operation is executed after erasure reconfirmation of the selected erasure target file is performed. According to such a method, when erasing a plurality of files recorded on the same date, it is not necessary to repeat the operation of reproduction, confirmation, erasure → reproduction, confirmation, and erasure as in the related art. Confirmation and deletion of files can be performed with simple operations.
