It has a function to display various information.

Next, the operation of the embodiment configured as described above will be described.

In this case, when a battery (not shown) is set, the main flow shown in FIG. 2 is executed.

First, when a battery is set and power is supplied to the system control unit 10, initial settings such as external conditions of the system control unit 10 and conditions for reading and writing audio data on the recording medium 11 are performed in step 201. .

Next, at step 202, clock adjustment is performed. To set the clock at this time, first, the setting button SEND
Is operated to display "hours and minutes" on the display 14, while only "hours" is blinked, and the increment button + or the decrement button-is operated to match the current time "hours". By operating the button SEND, only the "minute" is made to blink, and the increment button + or the decrement button-is operated to match the "minute" of the current time.

From this state, in step 203, clock counting is started. The clock count counts the time in day units. When a date change is detected by this count, the date of the calendar function is automatically incremented in the RAM 101 of the system control unit 10.

Thereafter, if the operation of the increment button + is determined in step 206 via steps 204 and 205, the selected date is incremented in step 207. In this case, as shown in FIG. 3, it is determined in step 301 whether today is February 28. here,
If it is not February 28, in step 302, the date of today is incremented, and in step 303, the number of audio data corresponding to the schedule of the date is displayed. Further, when February 28 is determined in step 301, it is determined in step 304 whether this year is a leap year. The determination of the leap year in this case is obtained from a predetermined arithmetic expression using the Christian era data managed by the calendar function of the RAM 101. If it is determined that the year is a leap year, at step 305, 2
The month 29 is set, and in step 303, the number of audio data corresponding to the schedule on the corresponding date is displayed. On the other hand, if it is determined that it is not a leap year, it is determined in step 306 whether voice data exists on February 29, and if voice data exists, in step 305, February 29 is set, and in step 303, The number of audio data corresponding to the schedule on the corresponding date is displayed. If no voice data exists on February 29, March 1 is set in step 307, and the number of voice data corresponding to the schedule on the corresponding date is displayed in step 303.

On the other hand, through steps 204 and 205,
If the operation of the decrement button-is determined in step 208, the selected date is decremented in step 209. In this case, as shown in FIG.
Then, it is determined whether today is March 1st. If it is not March 1, today's date is decremented in step 402, and in step 403, the number of audio data corresponding to the schedule of the date is displayed. Step 4
At 01, March 1 is determined, and at step 404, it is determined whether this year is a leap year. If it is determined that the year is a leap year, February 29 is set in Step 405, and Step 40 is executed.
At 3, the number of audio data corresponding to the schedule on the corresponding date is displayed. On the other hand, if it is determined that it is not a leap year, it is determined in step 406 whether voice data exists on February 29, and if voice data exists, in step 405,
February 29 is set, and in step 403, the number of audio data corresponding to the schedule on the corresponding date is displayed.
If no voice data exists on February 29, February 28 is set in step 407, and step 403 is executed.
Displays the number of audio data corresponding to the schedule on the corresponding date.

By incrementing or decrementing the selection date in this way, a desired date can be selected. In this case, the number of audio data is displayed as a schedule for the corresponding date. If the user wants to reproduce desired audio data, the user specifies the audio data and then operates the reproduction button PLAY of the operation button 12.

Then, at step 205, the play button PLA
The operation of Y is determined, and in step 210, the reproduction mode is set by the system control unit 10, and the reproduction process is executed. In this case, the digital audio data corresponding to the selected date recorded on the recording medium 11 is read out by the system control unit 10 and input to the digital signal processing unit 5,
Here, the signal is decompressed under the control of the system controller 10, further converted into an analog signal by the D / A converter 6, amplified by the amplifier 8 via the low-pass filter 7, and output from the speaker 9.

On the other hand, when it is desired to record audio data as a schedule for the selected date, the recording button REC of the operation button 12 is operated.

Then, in step 204, the recording button REC
Is determined, and in step 211, the recording mode is set by the system control unit 10, and the recording process is executed. In this case, when a voice is input to the microphone 1, the input voice is amplified by the amplifier 2, and unnecessary frequency domain components are cut off by the low-pass filter 3 in order to prevent the occurrence of aliasing noise. The digital signal is converted into a digital signal by a digital signal processor 4 and input to a digital signal processing unit 5, where it is subjected to compression processing under the control of the system control unit 10, sent to the system control unit 10, and stored in the recording medium 11 based on a predetermined format. Recorded corresponding to the selected date.

When the stop button STOP is operated during execution of the above-described reproduction and recording processes, or when the current operating position reaches the end position or the leading end position of the recording medium 11, the process exits from each process. Return to step 203.
