The recording / reproducing operation of the audio recording / reproducing apparatus having the above configuration will be described below. At the time of audio recording, an analog audio signal obtained from the microphone 1 is amplified by the microphone amplifier 2, the frequency band is limited through the LPF 3, and then converted to a digital signal by the A / D converter 4 via the analog switch 26. The signal is converted and input to the DSP 5 inside the main control circuit 6.

Here, when the audio signal input from the microphone 1 is higher than a predetermined reference level, for example, A /
When it is larger than -6 dB of the maximum range of the D converter 4,
When a pulse is output to the diode 21 connected to the terminal D11 of the main control circuit 6, electric charges are accumulated in the capacitor 22 and a voltage is applied to the transistor 24. As a result, the impedance between the microphone amplifier 2, the transistor 24, and the ground changes, the signal input to the microphone amplifier 2 is limited, and the gain is adjusted. The electric charge stored in the capacitor 22 is gradually discharged via the resistor 23.

Next, the DSP 5 compresses the input digital signal in accordance with the operation of a plurality of operation buttons and switches connected to the main control circuit 6, and compresses the compressed audio data into the main control circuit 6. The data is recorded in the semiconductor memory unit 10 through the D4 terminal. At this time, an address at which audio data is to be recorded is given to the memory control circuit 7 from the D3 terminal.
The write operation is controlled by the memory control circuit 7.

On the other hand, when performing reproduction, the main control circuit 6 reads out audio data recorded in the semiconductor memory section 10 under the control of the memory control circuit 7 and supplies it to the DSP 5 to expand it. The audio data expanded by the DSP 5 is D / A
The signal is converted into an analog signal by the converter 11 and the AMP 12
After that, the signal is output from the speaker 13 as sound.

In the above-described sound recording and reproducing operations,
The main control circuit 6 controls the drive circuit 9 to cause the display 8 to display various information such as an operation mode. Hereinafter, with reference to a flowchart shown in FIG. 4, main operations of the above-described audio recording / reproducing apparatus will be described based on operations of the main control circuit 6.

When the battery 18 is set and power is supplied, the main control circuit 6 first initializes the external conditions of the main control circuit 6 and the internal storage unit (step S1). After completing the initialization, the main control circuit 6 detects whether the power supply voltage of the battery 18 is a rated value (step S2). The rated value at this time is set to, for example, 1 V, and the main control circuit 6 determines whether the power supply voltage of the battery 18 is 1 V or more, or whether the impedance of the battery 18 is higher than the rated value based on the current flowing through the battery 18. Whether it is not or not is detected based on information from the DC-DC converter 20. That is, D1 of the main control circuit 6
A detection signal relating to the state of the battery 18 is input to the 0 terminal, thereby detecting whether or not the battery 18 has a usable capacity. As a result of the detection in step S2,
When it is detected that the battery 18 is in a usable state, the relay switch 25 is turned on and the memory card 3 is turned on.
The process proceeds to step S23 to determine whether or not 3 is mounted on the device body.

If it is detected in step S2 that the battery 18 is not in a usable state, the power supply to the entire audio recording / reproducing apparatus is stopped, and the battery 18 and each circuit are disconnected. Then, a switch (not shown) provided between them is turned off, and the fact that there is no capacity of the battery 18 is displayed on the display 8 (for example, a liquid crystal display unit) as a notification unit via the drive circuit 9. Then, it waits in this state until a usable battery 18 is set.

In step S23, first, the main control circuit 6 as a preliminary determination means determines whether or not the D13 terminal as a contact provided on the device body is connected to the memory card 33. A specific determination method using this preliminary determination means is to determine whether the contact pad 67 exposed on the side surface of the memory card 33 and connected to the ground 61 of the memory card 33 is connected to the D13 terminal. . If the contact voltage of the terminal D13 is equal to the power supply voltage (Hig)
If h) remains, it is determined that the D13 terminal is not connected to the contact pad 59 of the memory card 33, and the process shifts to step S24.

On the other hand, if the contact voltage of the D13 terminal changes from the power supply voltage (High) to the ground (ground) voltage (Low), it is determined that the D13 terminal is connected to the contact pad 67 of the memory card 33, and the process proceeds to step S3. I do.

The connection state between the D12 terminal as a contact provided on the device body and the memory card 33 is determined by the same method as the method for determining the connection state between the D13 terminal and the memory card 33. Although not shown, one of the contact groups 52 of the circuit board A50 that contacts the D12 terminal is connected to the ground 61 of the memory card 33.
It is connected to the.

In step S24, it is determined whether or not a predetermined operation button has been pressed in a state where the memory card 33 is not mounted on the device main body. When the predetermined operation button is not pressed, the apparatus stands by in this state. On the other hand, when the predetermined operation button is pressed, the process proceeds to step S8.

In the error display in step S8, the main control circuit 6 as a notification means emits a warning sound as a predetermined notification, for example, a signal with a duty ratio of 50% at a cycle of 1 kHz and 60 msec from the speaker 13 for 180 msec. Further, the fact that the memory card 33 is not mounted on the device body may be displayed on the display 8 as characters. In this case, the notification unit includes a function of generating a warning sound and a function of displaying characters. Step S
If YES in step S24, the process proceeds to step S8 to display an error. However, if the determination in step S23 is NO, the above-described step S8 is performed.
8 may be displayed.

If it is determined in step S23 that the memory card 33 is mounted on the main body of the apparatus, the flow shifts to step S3 to determine whether the memory card 33 is properly connected.

That is, in the flowchart shown in FIG. 5, first, predetermined test data is transferred to the memory card 33 (step S30) and recorded (step S3).
1). Then, the recorded test data is transferred to the memory card 3
3 from the memory card 3 (step S32).
3 is determined by the main control circuit 6 as determination means as to whether or not the test data recorded in the memory card 3 is normally read, that is, whether or not the memory card 33 is a card that can normally read and write. Check the data bus connection. In particular, when a block erase batch type non-volatile memory is used, data is written in the temporary recording medium unit 100a.
Perform for

In step S33, if the test data has been read out normally, the process proceeds to step S4 in FIG. 4, and if the test data has not been read out normally, the process proceeds to step S24 in FIG.

In step S4, the data stored in the semiconductor memory unit 10 of the memory card 33 is read, and based on the read data, whether the index is normally recorded in the semiconductor memory unit 10 is determined, that is,
It is determined whether the format of the semiconductor memory unit 10 is normal. If an unformatted one is inserted as the semiconductor memory unit 10, it is determined that the memory format is not normal, information indicating usage conditions is input to the index unit of the semiconductor memory unit 10, and It is confirmed whether or not to perform a memory format (initialization) as a process of inputting “0” (step S
5). That is, the display circuit 8 controls the drive circuit 9 to display a confirmation as to whether or not to perform the memory format.

In step S5, when the button for instructing the execution of the memory format is not pressed within a predetermined time, the drive circuit 9 is controlled and the semiconductor memory section 10 on the display 8 is not normal, so that it should be replaced. Is displayed (step S8). Further, a switch (not shown) provided between the battery 18 for supplying power to the entire audio recording / reproducing apparatus and each circuit is turned off. Thereafter, in order to replace the semiconductor memory unit 10, the control waits until the main power switch 19 is turned off (step S9), and when it is detected that the main power switch 19 is turned off, the relay switch 25 is turned off (step S9).
22).

On the other hand, when it is determined in step S4 that the memory format is normal, or in step S6
After the formatting process is completed, the process proceeds to step 7 to display the completion of the initial setting, and then the semiconductor memory unit 10
The current operation position is detected based on the information read from the index section (step S10). Thereafter, each circuit is set in a waiting state while detecting whether any of the operation buttons (operation members) of the audio recording / reproducing apparatus is pressed (step S11). The operation buttons in this case mean, for example, a record button REC, a play button PL, a fast forward button FF, and a fast reverse button REW.

In step S11, when it is detected that any one of the operation buttons is pressed, it is first detected whether or not the operated button is the record button REC (step S12), and if the record button REC is pressed. For example, DSP
5 to compress the audio information input from the A / D converter 4 and control the memory control circuit 7 to control the semiconductor memory unit 1
The recording process for recording in the audio data portion of 0 is started (step S13).

If the operated button is not the record button REC, the play button PL is detected next (step S14). Here, if the play button PL is pressed, the memory control circuit 7 is controlled to
0, read out the recorded data from the audio data part, send the data to the DSP 5 and perform decompression processing, and then enter a reproduction processing for transmitting audio information to the D / A converter 11 (step S).
15).

If the play button PL has not been pressed, it is detected whether or not the fast forward button FF has been pressed (step S16). If the fast-forward button FF is pressed, a fast-forward process is performed in which the operation position is sequentially fast-forwarded at an appropriate speed, for example, 20 times the speed of reproduction (step S17). If the fast-forward button FF has not been pressed, it is detected whether or not the fast-return button REW has been pressed (step S18). If the fast-return button REW has been pressed, a fast-return process for moving the operating position at the same speed as in the fast-forward operation starts (step S19).

Steps S13, S15, S17, S
When the stop button ST is pressed in each of the processes 19, the process exits from each process and returns to the step S11. If the operated buttons are not operation buttons for recording, reproduction, fast forward, fast rewind, etc., the main power switch 19 is turned off or the state of various setting buttons is detected (step S20). In step S20, when the power of the main power switch 19 is turned off, the information in the index section of the semiconductor memory section 10 is updated by controlling the memory control circuit 7.
The index information stored in the storage unit (not shown) inside the main control circuit 6 is transferred to the index unit of the semiconductor memory unit 10 (Step S21). When the index transfer process is completed, the relay switch 25 that supplies power to the entire audio recording / reproducing apparatus, that is, each circuit, is turned off (step S22).

When it is determined in step S20 that the main power switch 19 is not turned off, the setting button is detected, the state is stored in an internal storage unit, and the process returns to step S11. Here, the setting button is not a button actually provided in the audio recording and reproducing apparatus, but a recording button REC, a reproducing button PL, a stop button ST, a fast forward button FF, a fast rewind button REW, an erase button ERASE, and a voice activation ( Silence compression) button VAD
Of these, the button is substituted by several simultaneous presses.
