It may be recorded in an internal storage unit such as a semiconductor memory (not shown).

Next, the operation of this audio recording / reproducing apparatus will be described with reference to FIG.
This will be described with reference to FIG.

When the battery BAT is set and power is supplied to the main control circuit 8, the main control circuit 8 detects it by voltage detection, and this operation is started.

When the operation is started, first, the main control circuit 8
Performs various initial settings such as external conditions and internal storage (step S1). However, at this point, the main power switch 16 for instructing the power supply to the entire audio recording / reproducing apparatus is in the off state.

After completing the initial setting, the main control circuit 8 detects whether or not the main power supply switch 16 is in the ON state (step S2). If not, the main power supply switch 16 is turned on. Wait until.

On the other hand, when it is detected that the main power switch 16 is on, a switch (not shown) provided between the battery BAT for supplying electric power to the entire audio recording / reproducing apparatus and each circuit. Turn on the recording medium 10
The operation start position information and the operation end position information are read from, and the code mode, the operation condition, and the like are also read (step S3).

Next, the current operation position is detected based on the index information (operation position information) read from the recording medium 10, and the drive circuit 14 is controlled to display the detected position on the display 15 (step). S4).

Then, it is detected whether or not any operation button of this audio recording / reproducing apparatus is pressed, and if not pressed, each circuit is placed in a standby state until it is pressed (step S5).

When it is detected that any one of the operation buttons is pressed, first, the operated button is the record button RE.
It is detected whether or not it is C (step S6), and when the record button REC is pressed, the digital signal processing unit 5 is controlled to compress the audio information input from the A / D converter 4, A recording process for controlling the memory control circuit 9 to record in the audio data portion of the recording medium 10 is started (step S
7).

If it is determined in step S6 that the record button REC is not operated, then it is detected whether or not the play button PL is operated (step S8). If the play button PL is pressed here, the memory control circuit 9 is controlled to read the recorded data from the recording medium 10, and the digital signal processing section 5 is read.
To perform a decompression process, and enters a reproduction process for transmitting audio information to the D / A converter 11 (step S9).

If it is determined in step S8 that the play button PL is not operated, it is detected whether or not the fast-forward button FF is operated (step S10). If the fast-forward button FF is pressed here, a fast-forward process for sequentially fast-forwarding the operating position at an appropriate speed (for example, 20 times the speed during reproduction) is entered (step S).
11).

When it is determined in step S10 that the fast forward button FF is not operated, it is detected whether or not the fast return button REW is operated (step S12). If the fast-reverse button REW is pressed here, the fast-reverse processing is performed in which the operation position is sequentially moved at the same speed in the opposite direction to the case of the fast-forward (step S).
13).

If it is determined in step S12 that the rewind button REW is not operated, it is detected whether the transfer button TRANS is operated (step S14). If the transfer button TRANS is pressed at this point, a transfer process for transferring the data to an external device such as a personal computer by the light transfer LED 17 is started (step S15).

The steps S7, S9, S11,
When the stop button ST is pressed during the processes of S13 and S15, the ST flag, which is a flag indicating that the stop button ST has been pressed, is set to exit from these processes. Then, the process returns to step S5.

After step S15, whether the stop button ST is pressed to complete the process is detected by checking whether the ST flag is set (step S16). If the stop button ST is not pressed here, it is determined that the transfer process is completed, a warning sound is emitted from the speaker 13 that also serves as a warning means, and the process proceeds to step S18 to be described later to automatically power off the mode. To

When it is determined in step S14 that the transfer button TRANS is not operated, it is determined whether the main power switch 16 is turned off, or the state of other various setting buttons is changed. It is detected (step S17).

When it is determined that the main power switch 16 is not off, the state of the setting button is detected, the state is stored in the storage section (not shown) inside the main control circuit 8, and then the process returns to step S5.

On the other hand, in step S17, when the main power switch 16 is turned off, the memory control circuit 9 is controlled to erase the information in the index portion of the recording medium 10, and the main control circuit 8 is operated. The index information stored in the internal storage unit (not shown) is stored in the index unit of the recording medium 10 (step S18).

When this index transfer process is completed,
The main control circuit 8 also serving as a mode changing means turns off a power switch (not shown) for supplying power to the entire audio recording / reproducing apparatus to shift to the power-off mode (step S19), and returns to step S2.

Next, the process of transferring the data in step S15 will be described in detail with reference to the flowchart of FIG.

In this data transfer process, first, the LED 15a provided in the display 15 is blinked (step S21), and the STOP flag is cleared (step S22).

Here, as means for indicating that the data transfer process is in progress, for example, an LCD may be used in addition to the LED 15a. In the case of using the LCD, a voice to be transferred to a portion for displaying time. The amount of untransferred voice data with respect to the data may be converted into time and displayed, and the time display may be changed (subtracted) according to the data transfer amount. That is, for example, as shown in FIG. 4, the number 20 displayed on the LCD is 2 by the time the voice data is completely transferred.
It shows that it takes 0 second.

Also, when this LCD is used, as shown in FIG. 4, for example, the fact that the transfer is in progress is indicated by blinking the character "TRANS" in the LCD, and the transfer is continued. It may be indicated by displaying the character "REMAIN".

The blinking speed of the characters displayed on the LED 15a or the LCD may be changed according to the data transfer amount, for example. In this case, the blinking rate may increase (or decrease) the blinking rate of the LED 15a every time data is transferred, that is, as shown in step S32 of the flowchart of FIG. The blinking may be performed fast or slow in proportion to the transferred data amount.

Alternatively, as shown in steps S32 and S33 of the flow chart of FIG. 6, when the data transfer remaining amount becomes less than a predetermined amount (for example, remaining 10%) or less, the LED1
The blinking speed of 5a may be increased (decreased).

The blinking LED may also be used as a recording LED, for example. In this case, no additional configuration is required, so that the cost can be reduced. Furthermore, if the recording LED is made to emit light when transmitting the audio data in a color different from that used for recording, it may be clearer whether recording is being performed or transfer is being performed.

Then, it is judged whether or not the stop button ST has been pressed (step S23). If the stop button ST has not been pressed, the main control circuit 8 performs the transfer process.
Performs control for reading data from the main recording medium unit of the recording medium 10 to the temporary recording medium unit, and resets a counter N that manages the number of read data (step S
24), data is read from the main recording medium section of the recording medium 10 to the temporary recording medium section (step S25).

Next, in order to increment the data read number, 1 is set in the counter N for managing the data read number.
Is added (step S26).

Then, a code error detection signal is created (step S27). Examples of the code error detection signal include parity check, CRCC (cyclic code),
Although the Viterbi code or the like is normally used, in this embodiment, C
RCC is used.

Next, the voice data and the code error detection signal are transferred to an external device such as a personal computer (step S28), and then it is determined whether or not the data reading is finished, that is, the counter N finishes reading. Is determined (step S2).
9).

If the counter N is equal to or less than NEND, it means that the data reading is not completed, and the process returns to step S23. On the other hand, when the counter N is larger than NEND, the LED 15a is turned off (step S31), and at the same time, the data transfer process is terminated and the process returns.

If it is determined in step S23 that the stop button ST has been pressed, the STOP flag is set (step S30), and step S3 is executed.
Proceed to 1.
