The display member 7 is constituted by an LCD or the like, and displays various modes. Further, the flash memory 2 may be built in or may be a removable memory. The clock 5 is used for the CPU 1 to perform time measurement for detecting an automatic reproduction time based on the clock.

[0010] The setting of automatic reproduction for automatically reproducing predetermined data at an arbitrary set time is performed by selecting an object to be reproduced by the operation member 6 and then entering the menu mode to set the alarm in the alarm setting mode. The setting is performed by the user using the operation member 6 to set the time of the automatic reproduction.

In the above configuration, when recording, the microphone 8
Is input to the amplifier 9 and amplified by the amplifier 9.
After the high-frequency component is removed at 10, the digital signal is converted to a digital signal at the analog-to-digital converter 11 and input to the data compression / decompression unit 3. The data compression / decompression unit 3 performs a compression process on the input digital signal. The compressed audio data is written to the flash memory 2 under the control of the CPU 1.

At the time of reproduction, audio data stored in the flash memory 2 is read out under the control of the CPU 1 and sent to the data compression / decompression unit 3. The data compression / decompression unit 3 performs a decompression process on the input audio data. The expanded audio data is converted to a digital-to-analog converter 1
After being converted into an analog signal by 2 and its high-frequency signal removed by the LPF 13, the signal is amplified by the amplifier 14 and output to the outside via the speaker 15. FIG. 2 is a flowchart for explaining the overall operation of the digital recorder.
When a battery is loaded, this flow starts, and step S1 is executed.

In step S10, it is determined whether or not the fast-return switch has been turned ON by pressing the fast-return button. If YES, the process proceeds to step S11 to perform fast-return processing, and then proceeds to step S12.
If the determination in step S10 is NO, the process immediately proceeds to step S12. In step S12, it is determined whether or not the menu switch has been turned ON by pressing the menu button. If YES, the process proceeds to step S13 to perform menu processing, and then proceeds to step S14. If the determination in step S12 is NO, the process immediately proceeds to step S14.

In step S14, it is determined whether or not automatic reproduction is set. If NO, step S14 is executed.
Returning to step 2, if YES, the process proceeds to step S15 to determine whether or not the set time has come. Here, in the case of NO, the process returns to step S2, and in the case of YES, the process proceeds to step S16 to perform an alarm process and reproduce the specified reproduction target. Thereafter, the process returns to step S2. Here, the alarm processing includes a method of outputting a specific sound from the speaker 15 or a method of blinking characters on the display member 7 to notify the user.

FIG. 3 is a flowchart for explaining the details of the menu processing in step S13 described above. First, a recording mode setting screen is displayed in step S20. Next, the process proceeds to step S21, where it is determined whether the menu button is pressed again to turn on the menu switch. If YES, the process proceeds to step S24 to display a microphone sensitivity setting screen. The user can set the microphone sensitivity while viewing this screen. If the determination in step S21 is NO, the process proceeds to step S22 to determine whether the fast-forward switch has been turned ON. If the determination is YES, the process proceeds to step S25 to set the recording mode. If the determination in step S22 is NO, the process proceeds to step S23, where the quick return switch is turned on.
It is determined whether or not the recording mode has been set. If the answer is YES, the process shifts to step S25 to set the recording mode. Also,
If the determination in step S23 is NO, step S21

After the display processing in step S24, the process proceeds to step S26, where it is determined whether the menu button is pressed again and the menu switch is turned on, and YES
In the case of, the process proceeds to step S29 to display a screen for setting an automatic reproduction cancel time. Also, the determination in step S26 is N
In the case of O, the process proceeds to step S27 to determine whether or not the fast-forward switch is turned on. In the case of YES, the process proceeds to step S30 to set the microphone sensitivity. If the determination in step S27 is NO, the process proceeds to step S27.
The process proceeds to step 28, where it is determined whether or not the fast-return switch has been turned on. If YES, the process proceeds to step S30 to set the microphone sensitivity. If the determination in step S28 is NO, the process returns to step S26.

After the display processing in step S29, the flow advances to step S31 to determine whether or not the menu button has been pressed again to turn on the menu switch.
In the case of, return. If the determination in step S31 is NO, the process proceeds to step S32 to determine whether or not the fast-forward switch is turned on. If the determination is YES, the process proceeds to step S34 to determine whether T = 60 minutes. Here, T is a variable for setting the automatic reproduction cancellation time, and can be set in units of 5 minutes. Here, the maximum value of T is 60 and the minimum value is 0. If the determination in step S34 is YES, the process returns to step S31 because it is already the maximum value. If the determination is NO, the process proceeds to step S35 to add 5 minutes to the current value of T and extend T by 5 minutes. ,
It returns to step S31. At this time, a value obtained by extending T by 5 minutes is displayed on the display member 7.

If the determination in step S32 is NO, the process proceeds to step S33 to determine whether the fast-return switch has been turned on. If the determination is YES, the process proceeds to step S36 to determine whether T = 0 minutes. Judge. If the determination in step S36 is YES, the process returns to step S31 because it is already the minimum value. If the determination is NO, the process proceeds to step S37 to perform a process of subtracting 5 minutes from the current value of T to reduce T by 5 minutes. Then, the process returns to step S31. At this time, T is 5
The value reduced by the minute is displayed on the display member 7. If the determination in step S33 is NO, the process returns to step S31.

As can be seen from the above description, after displaying the screen for setting the automatic playback release time, if the user presses the fast forward button, T is extended by 5 minutes unless T reaches the maximum value. If the fast reverse button is pressed, T is set to 5 unless T reaches the minimum value.
Perform the process to shorten by minutes. In this way, the automatic reproduction cancel time is set.

FIG. 4 is a flowchart for explaining the details of the reproduction process in step S5 described above. First, after the reproduction is started in step S40, it is determined in next step S41 whether or not the data to be reproduced is the end (step S41). If NO here, the process proceeds to step S42 to determine whether or not the stop switch has been turned ON. If the determination in step S42 is NO, step S
Return to 41. If the determination in step S41 is YES, or if the determination in step S42 is YES, step S4
Proceeding to No. 3, the reproduction process ends. Next, proceeding to step S44, it is determined whether or not the reproduced data is an object of automatic reproduction (step S44), and in the case of NO, the process returns. In the case of YES, the next step S45
It is determined whether or not T = 0 minutes, and the process returns if YES. This is to prevent the automatic reproduction setting from being canceled when T = 0 because it is the same as the automatic reproduction setting time. If the determination in step S45 is NO, the process proceeds to step S46 to determine whether the time is within T minutes before the automatic reproduction set time. Here, in the case of NO, the process returns. In the case of YES, the process proceeds to step S47 to cancel the automatic reproduction setting, and then returns.
