During recording by a text recorder, by operating the I mark button I, an instruction (I) mark, which is a typist or a secretary instruction index mark, indicating the priority relationship between a plurality of sentences recorded in the semiconductor memory is recorded. Is enabled, and the text recorder can
By using this I mark, it is possible to specifically instruct a priority relationship by voice. Further, an index mark called an end (E) mark can be recorded by operating the E mark button E in order to indicate a break between a plurality of sentences.

Further, an external transfer circuit 16 which is a component of a transfer means is connected to the memory control circuit 6 and the system control section 12, and the external transfer circuit 16 serves as a member for transmitting data to the outside. The infrared light LED 17 is connected. Furthermore, the output terminal of the voltage comparator 18 is connected to the system control unit 12, and the voltage comparator 1
The input end of 8 is a PI as a data receiving member from the outside.
It is connected to the N diode 19.

The system control unit 12 further includes
The electromagnet 20 and the reed switch 21 are connected.
That is, in the audio recording / reproducing apparatus of this embodiment, the analog signal obtained from the microphone 1 is amplified by the amplifier 2, passed through the low-pass filter 3, and then converted into a digital signal by the A / D converter 4 to encode the code. It is input to the decoding / decoding circuit 5. The data encoded by the encoding / decoding circuit 5 is sent to the memory control circuit 6.

The system control section 12, which is a component of the audio data selection means, the transfer means, and the transfer selection means, operates in accordance with the operation of a plurality of operation buttons and switches, and the encoding / decoding circuit 5 and the memory control circuit. 6, semiconductor memory 7,
And the external transfer circuit 16 are controlled. That is, an appropriate address signal is given to the memory control circuit 6, and the audio data supplied from the encoding / decoding circuit 5 is recorded in the semiconductor memory 7.
Alternatively, the data recorded in the semiconductor memory 7 is read out and supplied to the encoding / decoding circuit 5.

The address, which is the information indicating the recording position of the audio information, may be stored in the semiconductor memory 7, and a storage unit (not shown) attached to the system control circuit 12 provided on the recording / reproducing apparatus side. It may be stored in a (semiconductor memory).

The read data decoded by the encoding / decoding circuit 5 is input to the D / A converter 8 and converted into an analog signal through the low pass filter 9. The signal output from the low-pass filter 9 is amplified by the power amplifier 10 and output as sound from the speaker 11 to the outside.

The system controller 12 also causes the display 14 to display various information such as the operation mode. In the present embodiment, the semiconductor memory 7 has a recording structure as shown in FIG. That is, the memory space is roughly divided into the index section 7A and the audio data section 7B.

The index section 7A is a voice data section 7B.
The operation start position information 7An (n = 1, 2, 3, ...) A and the operation end position information 7An (n = 1, 1) for each of the plurality of voice message files (that is, letters) 7B1, 7B2, 7B3, ... 2, 3, ...) b, recording date information 7An (n = 1,2,3, ...) c, mark information 7A
n (n = 1, 2, 3, ...) D, other code modes, operating conditions, etc. are recorded. In addition, operating position information 10AP indicating the current operating position with respect to the audio data portion 7B is recorded.

The data recorded in such a semiconductor memory 7 is transferred to the external transfer circuit 16 via the memory control circuit 6.
Is input to and is transferred to an externally connected device. That is, the external transfer circuit 16 converts the input data into serial electric signals, light, electromagnetic waves, etc., and transfers the data to an external connection device (not shown). In this embodiment, the infrared LED 17 transfers data as an optical signal to an externally connected device.

As a means for receiving data from an externally connected device, the system control unit 12 further amplifies a signal converted into electricity by inputting infrared light through the PIN diode 19. Alternatively, it is connected to the voltage comparator 218 for conversion.

Further, when data transfer is performed, it is necessary to notify the externally connected device of the start of data transfer.
As a means for this, the system control unit 12 is connected to an electromagnet 20 that transmits by using magnetism, for example. On the contrary, the reed switch 21 is connected to the system control unit 12 as a means for receiving a data transfer start signal from an externally connected device.

As means for transmitting the start of data transfer, other than this, a magnetic head or a Hall element is used as another means utilizing magnetism, or a solenoid is driven to convert it into mechanical means for data transfer. Is used, and the receiving side uses a method such as receiving a data transfer start with a micro switch, an LED or laser light emitting diode that uses light or infrared rays, or an optical shutter that uses a liquid crystal (LCD). The data transfer start signal may be transmitted by means of light, and the receiving side may receive the data transfer start signal by converting light from a PIN diode, a phototransistor or the like into electricity.
Alternatively, when a radio wave or a micro wave is used, an oscillator and an antenna may be used on the transmitting side, and an antenna and a low-pass filter as a receiver may be used on the receiving side. Furthermore, a specific sound or ultrasonic wave is output from the speaker to notify the start of transfer, the receiving side inputs the specific sound or ultrasonic wave input from the microphone, and upon recognition, the transfer start is received. Means may be used.

Next, the operation of the audio recording / reproducing apparatus having such a configuration will be described with reference to FIG. When the battery BAT is set and power is supplied to the system control unit 13, the system control unit 13 detects it by a voltage detection circuit (not shown) and starts the operation as shown in the flowchart of FIG.

That is, first, the external conditions of the system control unit 12 and the initial setting of the internal recording unit are performed (step S1).
However, at this point, the power SW 13 for instructing the power supply to the entire audio recording / reproducing apparatus is in the OFF state. After completing the initial settings, the system controller 12
Detects whether the power SW 13 is turned on or whether the read SW 21 is turned on (step S2).

If it is detected that the power SW 13 is in the ON state or the lead SW 21 is in the ON state as a result of the detection, the power SW 13 is provided between the battery BAT and each circuit for supplying power to the entire audio recording / reproducing apparatus. If the stop button ST is pressed at the same time when the power is turned on, the lead SW21 is turned on.
It is determined whether or not is turned on (step S
3), if it is this condition, it is determined that the data will be transferred,
Data transfer processing as described later in detail (step S4)
go to.

If the above conditions are not satisfied, the semiconductor memory 7
Information of the index section 7A is read. That is, the operation start position information 7Ana (however, n = 1, 2, 3, ...)
And operation end position information 7Anb (however, n = 1, 2, 3,
…) And so on. At this time, it is determined based on the data read from the semiconductor memory 7 whether the semiconductor memory 7 has already recorded the index normally, that is, whether the format of the semiconductor memory 7 is normal (step S5).

Here, when the unformatted semiconductor memory 7 is inserted, it is determined that the semiconductor memory 7 is not normal. In that case, the information indicating the usage condition is input to the index portion 7A of the semiconductor memory 7 and the voice is output. It is confirmed whether the memory format (initialization), which is the process of inputting "0" to the data section 7B, is performed (step S).
6). That is, the display 14 is caused to perform a confirmation display as to whether or not to perform the memory format.

If the button for confirming the memory formatting process (also used as the recording button REC) is pressed, the semiconductor memory 7 is formatted (initialized) (step S7), and after this formatting is completed, the display unit is displayed. 1
An initialization completion display is displayed at step 4 (step S8).

When the button for instructing not to format the memory (also used as the stop button ST) is pressed, the display 14 indicates that the semiconductor memory 7 is not normal and the semiconductor memory 7 should be replaced. Is displayed, and a switch (not shown) provided between the battery BAT and each circuit for supplying power to the entire audio recording / reproducing apparatus is turned off (step S).
9). After that, the power S is used to replace the semiconductor memory 7.
Wait until W13 is turned off (step S10), and if it is detected that it is turned off, the above step S2
Return to.

On the other hand, if the semiconductor memory 7 has been normally initialized, the current operation position is detected from the information (operation position information 7AP) read from the index section 7A after the completion of the initialization is displayed, and the display is displayed. The detected position is displayed at 14 (step S11). After that, each circuit is placed in a waiting state while detecting which of the operation buttons of the device has been pressed (step S12).

Then, when it is detected that any one of the operation buttons is pressed, first, the operated button is the record button R.
If it is EC (step S13), if the record button REC is pressed, the encoding / decoding circuit 5 is controlled to compress the audio information input from the A / D converter 4, and the memory control circuit 6 is started to start recording processing for recording in the audio data portion 7B of the semiconductor memory 7 (step S1).
4).

In this recording process, when the E mark button E is pressed, the E mark is recorded at the end of the voice message file (letter) in the voice data section 7B,
The new recording start position is recorded in the index section 7A as operation start position information for the next voice message file. In this way, the index information including the pair of operation start position information and end position information for one voice message file and the recording date and time is recorded, and new operation start position information is written at the next position. The E mark may be recorded as mark information next to the date / time information indicating the recording date and time instead of the audio data section 7B, or may be recorded in both the index section 7A and the audio data section 7B. You may.

Similarly, the instruction (I) mark can be recorded during this recording process. This I mark is, for example, when the recording button REC and I
By pressing the mark button I at the same time, the mark information is recorded in the mark information of the index portion 7A or in the voice message file, and by searching for this I mark at the time of fast-forwarding or returning, it becomes possible to reproduce from the desired recording position. Of course, since the audio recording / reproducing apparatus is a digital apparatus using the semiconductor memory 7 as a recording medium, the I mark can be recorded not only during recording but also later during stop. Since the recording and retrieval of this I mark are the same as those of the conventional device, detailed description thereof will be omitted.

When it is determined in step S13 that the record button REC is not operated, the reproduction button PL is detected (step S15).
If the play button PL is pressed here, the memory control circuit 6 is controlled to control the audio data section 7B of the semiconductor memory 7.
The recorded data is read out, sent to the encoding / decoding circuit 5 for decompression processing, and reproduction processing for sending audio information to the D / A converter 8 is started (step S16).

When the play button PL is not pressed, whether or not the fast-forward button FF is pressed is detected (step S17). If the fast-forward button FF is pressed, the fast-forward process of sequentially fast-moving the operating position at an appropriate speed (for example, 20 times that at the time of reproduction) is started (step S18).

If the fast-forward button FF is not pressed,
Whether the return button REW is pressed or not is detected (step S19). If the return button REW is pressed, a return process for moving the operating position at the same speed in the opposite direction to the case of the fast-forwarding is started (step S2).
0).

Steps S14, S16, S18, S
When the stop button ST is pressed, each process of 20 exits from each process and returns to step S12. If the operated button is not a button for recording, playing, fast-forwarding, returning, etc., it is detected whether the audio data to be transferred to the external device is selected or not (step S21). this is,
It is detected depending on whether or not the read SW 21 is turned on.

When the read SW 21 is turned on, the transfer data is selected as will be described in detail later (step S22), and then the process proceeds to step S4 to perform the data transfer process.

On the other hand, if the lead SW 21 is not turned on, the power is turned off or the state of various setting buttons is detected (step S23). Power SW13 is power supply OF
When the F operation is performed, the memory control circuit 6 is controlled to erase the information in the index section 7A of the semiconductor memory 7,
The index information stored in the storage unit (not shown) inside the system control unit 12 is recorded in the index unit 7A of the semiconductor memory 7 (step S24). When this index transfer process is completed, the power switch (not shown) for supplying power to the entire device, that is, each circuit is turned off (step S25). Then, the process returns to step S2.

If it is determined in step S23 that the power SW 13 is not OFF, the state of the setting button is detected, the state is recorded in the internal recording section, and the process returns to step S12. Note that here, the setting button is not the button actually provided on the device,
Record button REC, Play button PL, Stop button ST,
It is a button that is substituted by pressing some of the fast-forward button FF, the return button REW, the I-mark button I, the E-mark button E, and the voice activation button VAD at the same time.

Next, regarding the transfer data selection processing in step S22, referring to the flowchart of FIG.
It will be described in more detail. First, it is selected whether to transfer all the audio data on the semiconductor memory 7 or select the audio data to be transferred in advance and then transfer (step S31).
At this time, a slider switch, a tact switch, a rotary encoder, etc. are available as a method of actually selecting. Hereinafter, steps S33, S34, S36, S37,
The selection method of S39 and S41 is performed in the same manner.

When all data transfer is selected in step S31, the system controller 12 sets the all transfer mode (step S32). On the other hand, if the data is selected as the transfer mode in step S31, then it is selected in letter units to select whether or not to transfer (step S33). “Select by letter”
Then, which letter, ie, voice message file, is to be transferred is selected (step S34). At this time, a plurality of letters may be selected. The selected letter number is stored in the storage unit (not shown) inside the system control unit 12 (step S35).

If it is selected in step S33 that the letter unit is not selected, or after the letter number selected in step S35 is stored, then the date,
The time unit is selected to select whether or not to transfer (step S36). Here, "Select by date and time"
If is selected, which date and time are to be transferred next is selected (step S37). Then, the selected date and time are stored in the storage unit (not shown) inside the system control 12 (step S38).

If no selection by date or time is selected in step S36, or after the selected date and time are stored in step S38, then
It is selected in mark units whether to transfer or not (step S39). If "transfer in mark units" is selected, then the system control unit 12 sets the transfer mode to mark unit transfer mode (step S40). The mark here refers to an instruction (I) mark indicating a priority relationship between the plurality of sentences, or an index mark for simply finding the beginning of data.

After step S39 or step S40, it is selected whether the index is minimized and then transferred (step S41). Here, if you select "Make the index minimum before transferring", then
The system control unit 12 sets the transfer mode to the index minimum mode (step S42).

In the above description of the transfer mode, there is only one storage unit (not shown) of the system control unit 12 for recording the transfer mode state, and the contents of the storage unit are rewritten. It is also possible to secure a storage unit for recording only the type of transfer mode, for example, a memory, and record whether each mode is valid or invalid so that a combination of a plurality of modes can be determined.

Next, the data transfer process in step S4 will be described in more detail with reference to the flowchart of FIG. First, it is determined what mode is selected when the transfer data is selected in step S22 (step S51). If the data transfer process is determined by the data transfer determination in step S3, the all transfer mode is set.

In the case of the all transfer mode, it is next judged whether or not it is the index minimum mode (step S5).
2) In the index minimum mode, all audio data on the semiconductor memory 7 is transferred while minimizing the index (step S53). If it is not the index minimum mode, the index is not minimized and the semiconductor memory 7
All the above audio data are transferred (step S54).

On the other hand, when it is determined in the above step S51 that the transfer mode is not the full transfer mode, it is next determined whether or not the transfer letter number is stored in the storage section (not shown) inside the system control section 12 (step S55). ). When the transfer letter number is stored (there is a transfer letter number), it is next determined whether or not the index minimum mode is set (step S56). If the index minimum mode is selected, the index is the same as the transfer letter number while the index is minimized. All the letters (voice message files) are transferred (step S57). If not in index minimum mode,
All the letters having the same number as the transfer letter number are transferred without minimizing the index (step S58).

If there is no transfer letter number in step S55, it is next determined whether or not it is the mark unit mode (step S59). If it is the mark unit mode, then it is judged whether it is the index minimum mode (step S60). If it is the index minimum mode, a mark is added by the letter of the audio data on the semiconductor memory 7 while minimizing the index. All the letters are transferred (step S61). If the mode is not the minimum index mode, the index is not minimized and all the letters marked with the voice data letters on the semiconductor memory 7 are transferred (step S62).

Next, a method for minimizing the index will be described with reference to FIG. The audio data is largely divided into an index section 7A and an audio data section 7B as shown in FIG. When reproducing the audio data, the data is read in order from the left of the index section 7A in the figure. 7A1
In a and 7A1b, the start address and end address of the voice message file 7B1 to be reproduced first are recorded. When the voice data is reproduced up to the end address 7A1b, the voice message file 7B2 having the addresses 7A2a to 7A2b is reproduced next, and the voice message file is reproduced according to the address information of the index section 7A. Therefore, when transferring audio data, the transfer order is 7B1, 7B2, 7B3.
If the transfer is performed in the same order as the reproduction order of the audio data of the index section 7A, the transfer destination apparatus can reproduce the audio data without the 7A index section.
The data transfer amount can be reduced by the amount corresponding to the index portion of.

As described in detail above, according to this embodiment,
When the recorded data is transferred, the data to be transferred is selected by a data selection operation means in a specific condition, that is, a data attribute unit such as a letter unit, a mark unit, a date unit, or a time unit, and then the transfer is performed. Alternatively, the amount of data to be transferred is minimized before the transfer is performed by, for example, rearranging with the index being minimized before the transfer is performed, so that required audio data can be sent quickly without waste.

Although the above embodiment has been described by taking the case of audio data as an example, the present invention can of course be applied to a recording apparatus that handles all kinds of data including image data.
