Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an audio recording device that records and reproduces audio as a digital signal.

[Prior art and its problems] In recent years, there has been a tendency for small electronic calculators to become more and more sophisticated. It is being considered to take it out and use it.

In the past, however, there has been a system that has achieved this function, such as Japanese Patent Application No. 13181/1981, proposed by the present applicant. In other words, this device displays pre-stored numerical data on a display means and also uses voice as information regarding the numerical data.In particular, for recording and playback of voice, multiple addresses are provided in the key personnel department. By operating the key, the storage area of the audio recording unit corresponding to the operation key is specified and the encoded audio is stored in the memory fl area, and then, by operating the address designation key again, the storage area corresponding to the operation key is specified. By specifying a storage area of the audio recording section, the audio code stored in the storage area is read out and audio is generated.

However, with this device, each time you want to record or play back audio, you have to select the desired one from among multiple address designation keys and specify the storage area of the audio recording section, so this operation is time-consuming. It has the drawbacks of being expensive, cumbersome to handle, and difficult to use.

Moreover, if the specified key is operated incorrectly, not only will the audio not be recorded in the intended storage area, but there is also the risk that it will be impossible to retrieve the desired audio from that storage area.

[Object of the Invention] This invention has been made in view of the above circumstances, and it is possible to record audio data in order from the empty storage area of the audio storage means when recording audio, and the operation for audio recording is easy. Moreover, it is an object of the present invention to provide a voice recording device that can reliably prevent erroneous operations.

[Summary of the Invention] A voice recording device according to the present invention waits for a voice recording command from an input means, detects an empty voice data storage area of a voice storage means having a plurality of voice data storage areas, and records the empty voice data storage area. The configuration is such that the audio data input from the audio input means is digitized and stored in order.

[Embodiments of the invention] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the circuit configuration of the same embodiment.

In the figure, reference numeral 1 indicates a key manual section, and this key manual section 1 includes a numeric keypad 1a, a function key 1b, a recording rREc

)-11 FTJ key 1g, cursor "←" key 1h1 cursor "→" key 11, and secret designation key 1j.

This input data of the key manual section 1 is sent to the control section 2.

This III 111 section 2 is composed of a ROM, etc., and stores various control programs.

Further, the control section 2 outputs address data, numerical codes, and various operation commands, and sends operation commands to the display section 3, use area control section 4, use column 1lltit section 5, and voice control section 6, respectively. In addition to giving the normal area register 7, secret area register 8, display data memory section 9
, the code number memory section 1o, and the register section 11 with address data and read/input commands.

Here, if the maximum audio data storage area is 10g, the normal area register 7 is composed of 10 bits as shown in FIG. 3(a), and the pit corresponding to the area in use is set to 1. I have to. Similarly, the secret area register 8 is made up of 10 bits as shown in FIG. 3(b), and the bit corresponding to the area used in the secret state is set to "1".

The display data memory section 9 stores display data corresponding to the audio data storage area, and has 1 to 10 storage areas corresponding to the audio data storage area, as shown in FIG. The code number memory unit 10 stores the code number when secret designation is made. Register section 11
When the rMDFJ key 1f is powered by the key power section 1, the MDF flag 111 is set to "+1" and the area number that needs to be changed is temporarily stored.

The used area control unit 4 initially sets the area number in the current area register 12 to “0” and compares it with the contents of the normal area register 7 and secret area register 8 while counting up by +1, and sends this result to the control unit 2. Send. Then, the used column control section 5 searches the state of the corresponding column by specifying the address of the used column memory section 14 by the address counter 13.

As shown in FIG. 5, the used column memory unit 14 has a total of 32 columns, with column addresses consisting of 3 bits 0-7 and row addresses consisting of 2 bits O-3.

The output of the address counter 13 is also sent to the label ROM 15. This label ROM 15 is as shown in FIG.
O corresponding to the number of columns in the column memory section 14 used above
It has 31 storage areas, and each area stores the start address, end address, and bit rate of the audio memory section 17, which will be described later. Here, the bit rate is a sampling rate corresponding to the maximum recording time in the audio memory unit 17, and is set here to correspond to 16 seconds. The contents of this label ROM 15 are sent to the audio memory section 17 via the address counter 16 in response to a command from the audio control section 6. In this case, address counter 16
Commands from the voice control section 6 are also given to the voice control section 6.

Here, the audio memory section 17 has #O to #O as shown in FIG.
It has a total of 32 audio data storage areas #31.

In this case, the start address and end address of these audio data storage areas are 0 to 31 of the label ROM 15 described above.
Here, the audio data storage area #1 is at the start address A (N, end address AO2), the audio data storage area #2 is at the start address AO3, the end address AO4, and so on. Similarly #31
The audio data storage areas are set at a start address A63 and an end address A64, respectively. Further, in this case, the audio memory unit 17 can store audio data equivalent to 0.5 seconds for each audio data storage area #0 to #31, or 16 seconds in total, depending on the bit rate of the label ROM 15. .

The command from the voice control unit 6 is ADM (Ad a pt
ive Delta Modulation) is also provided to the synthesis unit 18. An A/D-D/A converter 19 and an amplifier section 20 are connected to the ADM synthesis section 18, and an audio input section 21 such as a microphone and an audio output section 22 such as a speaker are connected to the amplifier section 20.

Here, the ADM synthesis section 18 uses the converter 1 at the time of recording.
The current digital value of the audio signal digitized and given by 9 is compared with the previous digital value, and if the current digital value is large, it is quantized as "1", and if the previous digital value is large, it is quantized as rOJ. The digital signal read out from the audio memory section 17 is stored as audio data in the audio memory section 17, and on the other hand, during playback, the digital signal read out from the audio memory section 17 is converted inversely to that during recording, and converted into an analog signal by the converter 19. The signal is then output to the amplifier section 20 side.

Next, FIG. 2 explains the display screen of the display section 3.

In this case, the display section 3 has an input data display section 31 for eight digits in the center of the screen. 1 with audio data storage area numbers 1 to 10 attached to the upper right of this input data display section 31.
It has 0 audio area display sections 32. This audio area display section 32 displays the audio data storage area currently in use. Furthermore, between each digit of the input data display section 31, there is a dotted display section 33 that serves as both a decimal point display and a remaining amount of recording time.
Numbers 12, . . . , 16 are attached.

All of the dotted display sections 33 are lit at the start of recording, and turn off one by one as the recording time elapses, and the remaining recording time can be determined from the lighting status of the dotted display sections 33 at this time. We are making it possible to do so. Furthermore, in the upper left of the numerical data display section 31, there is a recording r of the key human power section 1.

Furthermore, E at the left end of the display screen is an error display, M is a memory display indicating that data is stored in the memory, "-" is a minus display, rKJ is a constant lock display, and "÷" at the right end of the display screen is a memory display indicating that data is stored in the memory. ""x"r-J r+J is a display indicating the operation status of the function key 11) of the key manual section 1.

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

First, the case of recording will be explained according to the flowchart of FIG.

In this case, first r of the key human power section 1 is used as a voice recording command.
Press and operate the RECJ key 1C. Then step A
1, press cursor key 1h.

11 is determined. If there is no key operation, the process proceeds to step A2; if there is a key operation, the process immediately proceeds to step A4, which will be described later.

In step A2, in response to a command from the control unit 2, the used area control unit 4 sets the area number of the current area register 12 to the first [
Set to Oj. Then, in step A3, the area number of the current area register 12 is incremented by 1.

In this state, the process proceeds to step A4, where the usage area control unit 4
At , the contents of the normal area register 7 and secret area register corresponding to the area number of the current area register 12 are checked. In this case, the first bit of the four-way area register 7 and secret area register 8 is “1” in use.
”, the answer is YES and the process returns to step A3, the area number in the current area register 12 is further incremented by 1, and the same operation is repeated. On the other hand, if the first bits of the normal area register 7 and the secret area register 8 are unused "0", the result is No and the process proceeds to step A5.

In step A5, the used column control section 5 sets the contents of the address counter 13 to "0" according to a command from the control section 2.

Then, in step 80, if there is input data from the key human power section 1, it is stored in the display data memory section 9.

In this state, the process proceeds to step A7, where an empty column in the used column memory section 14 is searched. In this case, the empty status of the column in the used column memory section 14 corresponding to the content "0" of the address counter 13 is searched. If the result is that the column is not empty, the process proceeds to step As, where the contents of the address counter 13 are incremented by 1 and set to "1".
Return to step A7 and repeat the same operation. in this case,
The same operation is repeated while incrementing the contents of the address counter 13 by 1 until an empty column is found.

Thereafter, when an empty column is found in step A7, the process proceeds to step A9, where the area number of the current area register 12 determined in step A4 is written into the used column memory section 14. Then, proceed to step AIO.

In this step AIO, the address counter 13 corresponding to the column of the used column memory section 14 into which the area number of the area register 12 is currently written in step A9 is
The contents of are given to the label ROM 15.

Thereby, recording is started in step A11. In this case, the audio data storage area of the audio memory section 17 is designated by the start address and end address written in the storage area of the label ROM 15 specified by the address counter 13 in step A10. In this state, the audio input from the audio input section 21 is passed through the amplifier section 20 to the A/D-D/A converter 19.
The signal is digitized here and then provided to the ADM synthesis section 18. Then, the ADM composite product 18 compares the current digital value with the previous digital value, and if the current digital value is larger, it is set as "1" and the previous digital value is set as "1".
If it is large, it is quantized as "0" and the resulting digital signal is stored as audio data in a designated storage area of the audio memory unit 17.

Here, if the AC key (not shown) of the key operator 1 is operated in step A12, the recording state in step A11 is forcibly terminated, and the recording is ended. However, in the recording at step A11, if the recording time is long and the audio data at this time does not all fit within the designated storage area of the audio memory unit 17, the audio control unit 6 generates an EO8 signal. This is then sent to the υ control section 2.

Then, in step A13, it is checked whether the contents of the address counter 13 are r31J, that is, whether all columns of the used column memory section 14 are in the used state. If the content at this time is YES, the recording state is forcibly terminated, but if the content is NO, the process returns to step A8.

In this step 88, the content of the address counter 13 is further incremented by 1 again, and the process returns to step A7, where the vacant status of the corresponding column in the used column memory section 14 is searched. Then, when an empty column is found, step A9 is performed again.
, the process proceeds to step A11 via step A10, and the audio data is subsequently stored in the audio storage area of the audio memory unit 17 corresponding to the start address and end address of the storage area of the label ROM 15 specified by the address counter 13 in step AIO. is memorized.

In the same manner, steps A7 to
The operation A13 is repeated.

Here, if the recording time is about 1.5 seconds, for example, three of the voice storage areas of the voice memory section 17 and three columns of the used column memory section 14 will be used as the first voice data storage area. .

Note that such voice recording will be performed after all the columns in the used column memory section 14 are in use and there is no space left in the voice storage area of the voice memory section 17, that is, when the recording interval reaches 16 seconds. Recording becomes impossible.

By the way, the relationship between the key operations in the key manual section 1 and the display on the display section 3 during such recording is shown in FIGS. 11 and 12.
It will look like the figure.

First, in the case of audio recording only, the rREcJ key 1C is pressed from the initial state shown in FIG. 11(a) as shown in FIG. 11(b). Then, rREcj is displayed on the display section 3, and the audio area display section 32 corresponding to the audio data storage area number "1" is lit. In this state, the audio to be recorded is input as shown in FIG. Then, as shown in the same figure (d), rACJ is
Recording ends when a key (not shown) is operated. In this case, the number of dotted display sections 33 corresponding to the recording time is turned off,
The remaining number of dots display section 33 displays the remaining recording time m.

Next, in order to perform a different recording, first operate the cursor "→" key 11 as shown in FIG. 3(e).

Then, the audio area display section 32 corresponding to the audio data storage area number "1" flashes. Following this, when the cursor "→" key 11 is operated again as shown in FIG. 2(f), the audio area display section 32 corresponding to the audio data storage area number "2" blinks this time. In this state, as shown in the same figure (Q), the rRECJ key 1cJ is pressed again.
Press If. Then, rREcJ is displayed on the display section 3, and the audio area display section 32 corresponding to the audio data storage area number "2" is turned on.

In this state, the audio to be recorded is input as shown in FIG. Then, as shown in Figure (i), the key human power section 1
If you operate the rAC, J keys (not shown) at , this recording will end.

Thereafter, recording of different contents is performed by repeating the same operation.

On the other hand, in the case of area-designated recording, first operate the rsHI FTJ key 1g, as shown in FIG. 12(a). Then, "SJ" is displayed on the display section 3, and if the audio data storage area numbers "1" and "2" are in use, the audio data storage area numbers "1" and "2" are displayed.
The audio area display section 32 corresponding to the button turns on. Here, if it is desired to input display data, input, for example, rll-23J from the key input section 1, as shown in FIG. 2(b). This display data is displayed on the display section 3. From this state, in order to specify an area, the cursor "→" key 11 is operated as shown in FIG.

In this case, if the operation is performed three times in a row, the audio area display section 32 corresponding to the audio data storage area number "3" becomes blinking. Then, as shown in the same figure (d), rR
Press and operate EcJ key 1C.

As a result, the display section 3 displays rREC instead of rSJ.
l is displayed. In this case, in the flowchart of FIG. 8, it is determined in step A1 whether there is a cursor key operation, and the process immediately proceeds to step A4. And this step A
4, the contents of the normal area register 7 and the secret area register 8 corresponding to the area number "3" of the area register 12 are checked, and if they are not in use, step A is executed.
You will be able to proceed from 5 onwards. The display data inputted in FIG. 12(b) is stored in the display data record section 9 corresponding to the area number of the current area register 12 in step 80. Thereafter, the audio to be recorded is input as shown in FIG. 2(e). And the same figure (f)
As shown in the figure, by operating the rACJ key (not shown) on the key operator 1, the area-designated recording is completed.

Thereafter, the second and subsequent recordings are performed by repeating the same operation.

Next, audio reproduction will be explained according to the flowchart of FIG.

In this case, first r of the key human power section 1 is used as a voice playback command.
Press and operate the PLAYJ key 1d. Then, in step B1, it is determined whether there is a cursor key operation to output a playback cue command, and if there is no key operation, step B2
If there is a key operation, the process immediately proceeds to step B4, which will be described later.

In this step B2, the used area control section 4 initially sets the area number of the current area register 12 to rOJ according to a command from the control section 2. Then, in step B3, the area number of the current area register 12 is incremented by 1.

In this state, the process proceeds to step B4, where the contents of the normal area register 7 and secret area register 8 corresponding to the area number of the current area register 12 are checked by the used area control unit 4. In this case, the first bits of the normal area register 7 and the secret area register 8 are unused “0”.
” then N.

Then, the process returns to step B3, the area number in the current area register 12 is further incremented by 1, and the same operation is repeated. On the other hand, normal area register 7 and secret area register 8
If the first bit of is "1" indicating that it is in use, the answer is YES and the process proceeds to step B5.

In step B5, the used column control section 5 sets the contents of the address counter 13 to "0" according to a command from the control section 2.

In this state, the process proceeds to step B6, and the corresponding column in the used column memory section 14 is searched. In this case, a search is made to see if the column in the used column memory section 14 corresponding to the content "0" of the address counter 13 corresponds to the area where the match was found in step B4. As a result, if it is not the corresponding column, the process proceeds to step B7, where it is determined whether the content of the address counter 13 is "31" or not. If YES here, the subsequent reproduction process is terminated.

On the other hand, if NO, the process proceeds to step B8, in which the content of the address counter 13 is incremented by 1 to "1", and the process returns to step B6 to repeat the same operation. In this case, the same operation is repeated while incrementing the contents of the address counter 13 by 1 until the corresponding column is found.

After that, when the corresponding column is found in step B6, the process proceeds to step B9, and the contents of the address counter 13 corresponding to the corresponding column in the column memory section 14 are stored in the label RO.
Given to M15. In this case, if display data corresponding to the contents of the current area register 12 is stored in the display data memory unit 9 in step BIO, this data is read out and displayed on the display unit 3.

After that, the process advances to step 811 and playback begins. In this case, the audio data storage area of the audio memory section 17 is
In step B9, the start address and end address stored in the storage area of the label ROM 15 designated by the address counter 13 are designated. In this state, a digital signal corresponding to the audio data is read from the designated audio data storage area of the audio memory section 17. Then, this signal is given to the ADM combining section 18,
Here, the signal is reversely converted to that during recording, and after being converted into an analog signal by the A/D/D/A converter 19, it is applied to the audio output section 22 via the amplifier section 20, and is output as audio.

After that, the process advances to step B12, and the key operation or EO3
Becomes a signal holder.

Here, if the audio data for one playback is stored across multiple storage areas of the audio memory section 17, the audio control section 6 generates an EO8 signal, which is sent to the control section 2. Then, in step 813, it is checked whether the content of the address counter 13 is "31". If the content at this time is YES, the reproduction is forcibly terminated, but if the content is No, the process returns to step B8.

In this step B8, the contents of the address counter 13 are roughly incremented by 1 again, and the process returns to step B6, where the corresponding column in the used column memory section 14 is searched again. and,
When the corresponding column is found, the process goes to step B11 again via step B9, and the voice storage area of the voice memory section 17 corresponding to the start address and end address of the storage area of the label ROM 15 specified by the address counter 13 in step A9 is read. , and subsequently reads the audio data.

Similarly, the operations of steps B6 to B13 are repeated until all the audio data is read out from the corresponding area of the audio memory section 17.

On the other hand, if the AC key (not shown) of the key operator unit 1 is operated in step 812 and it is determined in step B14 that it is the AC key, the reproduction state in step B11 ends.

Also, in step B12, the cursor "→" key 11
is operated, and if this key is confirmed in step B15, the process returns to step B3. Then, in step B3, the area number of the current area register 12 is incremented by 1. and,
After this, the next audio data storage area is reproduced by the same operation as described above.

Conversely, in step B12, the cursor "
←"key 1]) is operated, and if this key is confirmed in step B16, the process advances to step B17. This step B
At step 17, the area number of the current area register 12 is decremented by 1. Then, the process proceeds to step 818, where the area number of the current area register 12 decremented by 1 is compared with the contents of the normal area register 7 and secret area register 8, and if the corresponding bits of these registers 7.8 are rOJ, No.
The process returns to step B17 and the current area register 12 is
The area number is further decremented by 1 and the opening motion is repeated. on the other hand. If the bits of these registers 7.8 are in use and are "1", the answer is YES and the process returns to step B5. Therefore, the previous audio data storage area is reproduced by similar operations.

Next, in the case of playback cueing by specifying the playback address in advance, the cursor "→" key 11 is operated multiple times so as to correspond to the audio data storage area where the playback cueing is desired. Then, by this operation, the current area register 12
The area number is set to the content corresponding to the cursor key operation. In this state, when the rPLAYJ key 1d is operated, step B1 is reached in the flowchart of FIG.
In step B4, it is determined that the cursor key is present, and the process immediately proceeds to step B4. Then, in this step B4, the contents of the normal area register 7 and the secret area register 8 corresponding to the area currently specified in the area register 12 are checked, and if they are "1" in use, the process proceeds to step B5 and thereafter. . As a result, the pre-specified recording content is cued up and played back, and this is played back by the audio output section 22.
This will result in more output.

By the way, the relationship between the key operations in the manual key section 1 and the display on the display section 3 during such audio reproduction is as shown in FIGS. 13 and 14.

First, in the case of direct playback, from the initial state of FIG. 13(a) to the [PLAYJ key 1
Press d to operate. Then, rPLYJ is displayed on the display section 3, the audio area display section 32 corresponding to the audio data storage area number "1" is lit, and the recorded content corresponding to this is played back. Then, as shown in FIG. 3C, the reproduction ends with the audio area display section 32 corresponding to the audio data storage area number "1" remaining lit. In this case, if the [rPLAYJ key 1h is operated again, the next recorded content will be played back in the same way.

On the other hand, in the case of playback by specifying an area, that is, finding the beginning of playback, as shown in FIG. is operated three times, and the rPLAYJ key 1d is pressed to issue a playback cue command. Then,
As shown in FIG. 3B, rPLYJ is displayed on the display section 3, and the audio area display section 32 corresponding to the audio data storage area number "3" is lit.

From this state, the audio data storage area number "3"
The recording content corresponding to `` will now be played. In this case, if display data exists, for example rll-23
4 is displayed on the display unit 3. And the same figure (C)
As shown in the figure, the sound area display section 32 corresponding to the sound data storage area number "3" lights up and the display data r11
-23J remains displayed and the playback ends.

Next, the case of correction of display data corresponding to recorded content will be explained according to the flowchart of FIG.

In this case, first specify the audio data storage area to be corrected on the display unit 3 using the cursor keys of the key operator unit 1, and
DFJ key 1f is pressed.

Then, in step C1, the presence or absence of the MDF flag is determined. Here, if it is determined NO, step C2
Proceed to.

In this step C2, display data corresponding to the area number of the current area register 12 is displayed on the display section 3.

Then, the process proceeds to step C3, where the area number of the current area register 12 is set as the old area number and the register section 1
1 in the same register section 11 in step C4.
The MDF flag 111 of is set to +1.

In this state, the correction display data is inputted from the key input unit 1, and the audio data storage area of the correction light is specified by operating the cursor keys.

Next, when the rMDFJ key 1f is operated again, it is determined in step C1 that the MDF flag is present, so the process proceeds to step C5. In this step C5, the contents of the address counter 13 are temporarily set to "0", and the process proceeds to step C6.

In this step C6, it is determined whether the column contents of the used column memory unit 14 corresponding to the contents of the address counter 13 are the corresponding columns of the old area. In this case, if YES, the process advances to step C7, and the corrected area number of the current area register 12 is written in the column corresponding to the contents of the address counter 13 of the used column memory section 14. Then, in step C8, it is confirmed whether the content of the address counter 13 is "31", and if the answer is No, the content of the address counter 13 is incremented by 1 in step C9, and the process returns to step C6, and the same operation is repeated. On the other hand, if the answer is NO in step C6, the process immediately proceeds to step C8, where it is checked whether the content of the address counter 13 is "31", and if the answer is No, step C
At step C9, the contents of the address counter 13 are incremented by 1, and the process returns to step C6, where the same operation f) is repeated.

In this way, the contents of the address counter 13 become "31".
'', that is, it is determined whether all columns in the used column memory unit 14 correspond to the old area number, and the corresponding column is updated to the corrected area number in the current area register 12.

In this state, the process advances to step C10, where the old area number and MDF flag stored in the register section 11 are cleared, and then, in step C11, the input display data is changed to the display data corresponding to No. 1971 in the current area register 12. It is written to the area of the storage unit 9. Then, in step C12, the recorded content is played back for iLX, and the correction operation ends.

Incidentally, the relationship between the key operations in the key manual section 1 and the display on the display section 3 during such correction is as shown in FIG.

Now, press and operate the rsHI FTJ key as shown in FIG. Then, rSJ is displayed on the display unit 3, and the audio data storage area numbers ``1'' and ``1'' are temporarily displayed.
If the audio data storage areas ``2'' and ``3'' are in use, the audio area display sections 32 corresponding to the audio data storage areas ``1'', ``2'', and ``3'' are lit.

Here, if the audio data storage area number that requires correction is "3", the cursor "→
” key 11 three times in succession. As a result, the corresponding audio area display section 32 blinks.

From this state, when the rMDFJ key 1f is operated as shown in FIG. 3(C), data corresponding to audio data storage area number 3 is displayed.

In this case, rll-23J is displayed. After this display, the corrected display data is input as shown in FIG. 3(d). In this case, assume that r12-154 is input. Then, this data is displayed on the display section 3. In this state, the user operates the cursor "→" key 1f to designate the corrected audio data storage area number, as shown in FIG. 4(e). In this case, the fourth audio data storage area number is designated.

Thereafter, as shown in FIG. 2(f), the rMDFJ key 1f is operated again. Then, step C5 described in FIG.
- The corresponding column in the used column memory section 14 is corrected by the operation in step C9.

Note that the corrected display data inputted in FIG. 15(d) is stored in the display data storage section 9 in step C11. In this case, the display 13 displays rPLYJ. At the same time, data storage area number 4
The recorded content is played back, and the state shifts to the correction completion state shown in FIG.

Next, the relationship between the key operations in the key manual section 1 and the display on the display section 3 when erasing data will be explained with reference to FIG.

In this case, first, as shown in FIG.
Press the TJ key to operate. Then, "S" appears on the display section 3.
is displayed, and if the audio data storage area numbers ``1'', ``2'', and ``3'' are in use, it corresponds to the audio data storage number areas ``1'', ``2'', and ``3''. The audio area display section 32 becomes lit. Here, if the audio data storage area number you want to delete is "2",
As shown in FIG. 3B, the cursor "→" key 11 is operated twice in succession. As a result, the corresponding audio area display section 32 blinks. From this state, the rERAsEJ key 11e is operated as shown in FIG. Then, the data corresponding to the audio data storage area number "2" is erased, and the erasure is completed as shown in FIG.

Therefore, according to such a configuration, when recording audio,
By simply operating the rRECJ key in the key manual section, an empty audio data storage area in the audio memory section can be detected, and the audio data input from the audio input section can be stored in order from the empty audio data storage area. , the key operations for voice recording are much easier than those that store audio data while specifying the storage area by operating the area specification keys. This can be reliably prevented.

In addition, the audio memory section that stores audio data is divided into multiple audio data storage areas, and only the required number of storage areas are used depending on the length of the audio data for audio recording. , the storage area of the audio memory unit can be used efficiently, and effective audio recording can be performed.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications without changing the gist.

[Effects of the Invention] According to the present invention, the voice data input from the voice input section can be stored in order from the free voice data storage area of the voice means by simply operating keys on the input means, so that voice recording can be easily performed. It is possible to simplify the key operations, etc. for darning, and to reliably prevent erroneous operations during darning operations.
