BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an embodiment of a data recording / reproducing apparatus of the present invention.

As shown in FIG. 1, the data recording / reproducing apparatus of this embodiment is provided with a plurality of operation switches, and a switch (SW) operation unit 1 which functions as the folder selecting means or the association method selecting means, At the time of recording, an encoding unit 2 that encodes an input audio signal and / or image signal into audio data and / or image data of a predetermined encoding format, and the encoded audio data and / or image data A storage unit 3 functioning as the storage unit or the recording unit, which stores in a folder selected by the switch operation of the switch operation unit 1 in a recording medium having a plurality of folders by an association method determined for each folder. At the time of reproduction, the storage unit 3 reads the data from the recording medium according to the selection made by the switch operation of the switch operation unit 1. A decoding unit 4 for decoding the decoded data according to a predetermined decoding format, an audio reproducing unit 5 for reproducing the decoded audio signal as sound, and an image reproduction for reproducing the decoded image signal as an image. Part 6
And.

Further, as an external characteristic of this data recording / reproducing apparatus, an image pickup lens for image pickup is provided on the microphone arrangement surface (not shown).

In such a configuration, the quantized audio signal and / or image signal is encoded by the encoding unit 1 into audio data and / or image data in a predetermined encoding format. The sound data and / or the sound data is stored in the folder selected by the SW operation unit 1 among the plurality of folders of the recording medium by the storage unit 3. Is stored by a predetermined association method.

For example, if the recording medium has first, second, and third folders, when the first folder is selected, the image is displayed at a predetermined position of the audio data. The above audio data and /
Alternatively, the image data is stored in the first folder. When the second folder is selected, the voice data and / or the image data is stored in the second folder without associating the voice data with the image data. When the third folder is selected, the audio data and / or the image data are associated with each other on a file-by-file basis.
Alternatively, the image data is stored in the third folder.

At the time of reproduction, the audio data and / or image data read by the storage unit 3 is decoded by the decoding unit 4 into an audio signal and / or an image signal according to a predetermined decoding format. This decoded audio signal is reproduced as audio by the audio reproduction unit 5. Also, the decoded image signal is reproduced as an image by the image reproducing unit 6.

Here, when the SW operation unit 1 performs a predetermined operation during reproduction of the audio data of the first folder, the reproduction position of the audio data is updated to a predetermined position where the associated image data is stored. At the same time, the associated image data is reproduced. In the second folder, the audio data or the image data selected by the SW operation unit 1 is reproduced alone. Then, when the SW operation unit 1 performs a predetermined operation during reproduction of the audio data of the third folder, the associated image data is reproduced. However, in this case, unlike the case of the first folder, the reproduction position of the audio data is not updated.

Next, a specific configuration of the data recording / reproducing apparatus of this embodiment will be described.

FIG. 2 is a diagram showing a block configuration of an IC recorder to which an embodiment of the present invention is applied.

In FIG. 2, this IC recorder has an image pickup device (CCD) 11 for converting an image into an electric signal and a microphone (MIC) 12 for converting a sound into an electric signal.
And an image input unit 13 and a voice input unit 14.

The image input section 13 is for inputting image data from the image pickup element 11, and is provided with respective control circuits for iris, gain, white balance, etc., which are not shown, and A
It is composed of a / D converter. Each pixel signal output from the image sensor 11 is converted into a digital signal by the image input unit 13.

Similarly, the voice input section 14 receives voice from the microphone 12 and is composed of a microphone amplifier, a low-pass filter, and an A / D converter (not shown). The analog audio signal amplified by the microphone amplifier is converted into a digital signal by the A / D converter after the unnecessary frequency band is cut by the low-pass filter.

The digital signals of the image and the sound are converted into digital signal processing units (DSP) corresponding to the encoding unit 2.
15 is input. The digital signal processing unit 15 is controlled by the system control unit 16 corresponding to the storage unit 3 during recording, and encodes (compresses) each digital signal into audio data and image data in a predetermined encoding format in frame units. ) Do. Each encoded data is temporarily stored in a buffer memory (not shown) of the system control unit 16.

On the other hand, the digital signal processing unit (DSP) 15 at the time of reproduction is controlled by the system control unit 16 so that the audio data and the image data are decoded frame by frame from a buffer memory (not shown) of the system control unit 16. The process of (expanding) is performed.

Then, the decoded digital signal of the image is input to the image reproducing section 17. This image reproduction unit 17
Is composed of a video control circuit and a D / A converter (not shown). The image signal converted into an analog signal by the image reproduction unit 17 is displayed as an image on the image display unit 18 formed of, for example, a TFT-LCD.

Similarly, the decoded audio digital signal is input to the audio reproduction unit 19. The audio reproduction unit 19
It is composed of a D / A converter (not shown), a low-pass filter, and a power amplifier. The audio signal converted into the analog signal by the D / A converter is amplified by the power amplifier after the unnecessary frequency band is cut by the low-pass filter. Then, the sound is output from the speaker (SP) 20.

The system control section 16 is composed of a CPU, and in addition to the digital signal processing section 15, a display section 21, a recording medium (memory) 22 and an hour machine SW operation section 1 are provided.
Is connected to the operation unit 23.

Although not shown in the figure, the operation unit 23 includes a recording switch (RECSW) and a photographing switch (RELS).
W), play switch (PLAYSW), stop switch (STOPSW), fast-forward switch (FFSW), fast-reverse switch (REWSW), menu switch (MEN)
Various switches such as a USW), an erasing switch (ERASESW), and a folder changeover switch (FOLDERSW) are arranged for each function.

The display section 21 displays an operation mode when a predetermined sequence is started by the operation of any switch of the operation section 23, or an operation status thereafter. For example, when the recording switch (RECSW) is pressed, the elapsed recording time, the remaining recordable time, the file number, etc. are displayed. When the menu switch (MENUSW) is pressed, a display related to function selection such as microphone sensitivity (high / low), recording mode (standard / long) and alarm (on / off) is performed.

Further, when the system control unit 16 has a clock function, the current date and time is also displayed. These display contents may be displayed on the image display unit 18.

The recording medium 22 is composed of a non-volatile semiconductor memory such as a flash memory. At the time of recording, the audio data and the image data encoded by the digital signal processing unit 15 are stored via a buffer memory (not shown) of the system control unit 16.

Now, with reference to FIG. 3A, how data is recorded on the recording medium 22 used in the audio recording / reproducing apparatus will be described.

This recording medium 22 has a folder A (Ds
s_flda) 24A, folder B (Dss_fld)
b) Three folders of 24B and a folder C (Dss_fldc) 24C are provided.

Here, each folder 24A, 24B, 24
In C, an audio data file (for example, the extension is "wa"
v) file 25 and image data file (for example, file with extension "jpg") 26 are stored, and a reproduction order file (folder A having the reproduction order of files in each folder as table data) is stored. Playback order file (Flda_tb.dat) 27A, folder B Playback order file (Fldb_tb.dat) 27
B, folder C playback order file (Fldc_tb.da
t) 27C) is stored. However, a folder A reproduction order file (Flda_tb.dat) 27A and a folder B reproduction order file (Fldb_tb.dat) 27
B stores the reproduction order of only the audio data files 25 in the folders 24A and 24B, and the folder C reproduction order file (Fldc_tb.dat) 27C.
Stores the reproduction order including both the audio data file 25 and the image data file 26 in the folder 24C.

Further, the folder A (Dss_fld
a) A folder name data file (Fld_
name. dat) 28 and recovery data file (R
ecovery. dat) 29 is recorded.

That is, in this IC recorder, each of the folders 24A, 24B, 24C described above can change the folder name in the display section 21 to an arbitrary display name, and the folder name data file (F
ld_name. dat) 28, as shown in FIG.
Data indicating the displayed folder name is associated with each folder and recorded. Since the operator can easily recognize how the folder stores the audio data file 25 and the image data file 26 in association with each other, each folder name is set as a display name as shown in FIG. It is preferable. Of course, the operator can arbitrarily set this folder name.

The recovery data file 29
For some reason, the above folders 24A, 24B, 2
This is a file in which data for recovery is recorded when the data in 4C is destroyed.

In addition, the folder A (Dss_fld
a) 24A corresponds to the first folder for storing the image data file in association with the predetermined position of the audio data file. Therefore, the folder A (Dss
_Flda) 24A further stores a link data file (Flda_lk.dat) 30A having the link relationship between the audio data file 25 and the image data file 26 in the folder A as table data. That is, this link data file (Flda_
lk. dat) 30A, as shown in FIG.
The audio data file name, the link position (INDEX) in the audio data file, and the linked image data file name are recorded in association with each other. Here, those audio data file names and link positions (IN
The relationship between DEX) and the linked image data file name is as shown in FIG. That is, when the photographing switch (RELSW) of the operation unit 23 is operated during recording or reproduction of the audio data file, the image data file is recorded in the folder A (Dss_flda) 24A. At that time, The audio data file name during recording or playback and the image data file name taken are stored in this link data file (Flda_lk.dat) 30A together with the link position (INDEX) indicating the position on the audio data file at the time of shooting. It is supposed to be done.

In addition, the folder B (Dss_fld
b) 24B corresponds to the third folder for storing the audio data file and the image data file in association with each other on a file basis. Therefore, the folder B
The (Dss_fldb) 24B further includes an audio data file 25 and an image data file 2 in the folder B.
A link data file (Fldb_lk.dat) 30B having the link relationship of No. 6 as table data is stored. That is, this link data file (F
ldb_lk. As shown in (A) of FIG. 6, the dat) 30B records the audio data file name, the link number, and the linked image data file name in association with each other. Here, the relationship among the audio data file name, the link number, and the linked image data file name is as shown in FIG. 6 (B). That is, the operation unit 23 is activated during recording or reproduction of the audio data file.
When the photographing switch (RELSW) of the image data file is operated, the image data file is stored in the folder B (Dss_fld).
b) It is recorded in 24B, but each time the image is taken, the image data file name taken is stored with the ring number added to the audio data file name being recorded or played. Has become.

On the other hand, the folder C (Dss_
The fldc) 24C corresponds to the second folder which is stored independently without associating the audio data file with the image data file. Therefore, the folder C (Dss_fldc) 24C does not have any link data file.

As described above, the link data (related information) is stored in the link data file (Flda_lk.da).
t) 30A and link data file (Fldb_l
k. It is needless to say that such link data may be stored in the header area of the audio data file 25, instead of having the dat) 30B.

Next, the operation of the IC recorder thus constructed will be described.

FIG. 7 is a flow chart for explaining the main operation of this IC recorder. When the power of this IC recorder is turned on, first, the system control unit 16 performs a predetermined initialization (step S11). After that, the operation corresponding to the switch operation of the operation unit 23 is executed.

That is, the system control unit 16 first detects whether or not the recording switch (RECSW) is turned on (step S12), and the recording switch (RECSW) is detected.
If is turned on, a "recording process" subroutine, which will be described in detail later, is executed (step S1).
3).

On the other hand, the recording switch (RECS
If W) is not turned on, it is detected whether or not the photographing switch (RELSW) is turned on (step S14). If the photographing switch (RELSW) is turned on, details will be given. A "shooting process" subroutine as described later is executed (step S15).

When the photographing switch (RELSW) is not turned on, the reproduction switch (PLAYS)
It is detected whether or not W) has been turned on (step S1).
6) If the reproduction switch (PLAYSW) is turned on, a "reproduction process" subroutine, which will be described in detail later, is executed (step S17).

On the other hand, when the reproduction switch (PLAYSW) is not turned on, the fast-forward switch (FFS)
It is detected whether or not W) has been turned on (step S1).
8) If the fast-forward switch (FFSW) is turned on, the current file is changed to the next file by executing the "F.SKIP process" subroutine (step S19).

On the other hand, the fast-forward switch (FFS
If W) is not turned on, it is detected whether or not the rewind switch (REWSW) is turned on (step S20). If the rewind switch (REWSW) is turned on, The current file is changed to the previous file by executing the "R.SKIP process" subroutine (step S21).

If the rewind switch (REWSW) is not turned on, the menu switch (ME
It is detected whether or not the NUSW) is turned on (step S22), and if the menu switch (MENUSW) is turned on, the "menu setting process" subroutine is executed (step S23).

On the other hand, menu switch (MENUSW)
Is not turned on, the erase switch (ER
It is detected whether or not the ASESW) is turned on (step S24), and when the erasing switch (ERASESW) is turned on, the "erase process" subroutine is executed (step S25).

When the erase switch (ERASESW) is not turned on, it is detected whether or not the folder changeover switch (FOLDERSW) is turned on (step S26), and the folder changeover switch (FOL) is detected.
When the DERSW is turned on, the "folder switching process" subroutine is executed (step S2).
7). In this "folder switching process", the target folder for audio data file recording or playback is changed every time the folder switching switch (FOLDERSW) is turned on.
Folder A (Dss_flda) 24A → Folder B
(Dss_fldb) 24B → Folder C (Dss_fdb)
ldc) 24C → Folder A (Dss_flda) 24
This is a process of switching from A to ...

A folder changeover switch (FOLD)
If the (ERSW) is not turned on, the process returns to step S12.

Incidentally, in the above-mentioned step S19, "FS
KIP processing "," R.SKIP processing "in step S21," stop processing "in step S23, and step S2.
The processing of each sub-routine of "Erase processing" in No. 5 is carried out by using well-known technical means, and since it is not directly related to the content of the present invention, detailed description thereof will be omitted here.

However, the current folder is changed to the folder B by the "folder switching process" in step S27.
In the "F.SKIP process" of step S19 and the "R.SKIP process" of step S21 when the (Dss_fldb) 24B is switched to the image data file, the current audio data file 25 selected by the process is used. When 26 is linked, the image data file 26 is displayed (reproduced) on the image display unit 18.

Next, the "recording process" in step S13 described above.
The subroutine will be described with reference to FIG.

That is, first, whether or not the recording medium (memory) 22 is mounted, whether or not it is formatted,
Memory check is performed to check if there is free space, etc.
It is determined whether or not it is K (step S31). If the memory check result is NG, the speaker 20
A warning to that effect is issued by the display unit 21 (step S3).
2) Then, the "recording process" subroutine is ended.

On the other hand, the memory check result is OK.
If so, recording in the current folder is started (step S33). Here, the file name of the audio data file is automatically assigned.

Then, the photographing switch (RELS
It is detected whether W) is turned on (step S3).
4). Here, when the photographing switch (RELSW) is not turned on, the stop switch (STO
It is detected whether or not the PSW) is turned on (step S35), and this stop switch (STOPSW)
If it is not turned on, the recording medium (memory)
A memory check for checking whether or not there is still free space in 22 is executed (step S36). Here, if the memory check result is OK, the above step S34
Return to and continue recording.

On the other hand, if it is determined in step S35 that the stop switch (STOPSW) has been turned on, or if it is determined in step S36 that the memory check result is NG (no free space), Recording is stopped (step S37), and the "recording process" subroutine is terminated.

On the other hand, when it is determined in step S34 that the photographing switch (RELSW) is turned on, the current folder is the folder A (Dss_).
flda) 24A, folder B (Dss_fldb) 2
4B or folder C (Dss_fldc) 24C is determined (step S38).

When it is determined that the current folder is the folder A (Dss_flda) 24A, it is determined whether or not the recording medium (memory) 22 has a free space for storing the image data file. The imaging OK discrimination to be checked is executed (step S39). Then, when it is determined to be NG by the imaging OK determination, a warning to that effect is given by the image display unit 18 or the display unit 21 (step S40), and then the process proceeds to step S35. On the other hand, when it is determined that the image capturing is OK, the current position in the audio data file being recorded is acquired (step S41), and the image data is captured and the image data file is stored in the current folder (folder A (Dss_flda)).
24A) (step S42). The file name of the image data file is automatically assigned. Then, the acquired current position, the file name of the image data file, and the file name of the audio data file being recorded are stored in the current folder (folder A).
After writing the link data file (Flda_lk.dat) 30A of (Dss_flda) 24A) (step S43), the process proceeds to step S35.

In step S38, the current folder is the folder B (Dss_fldb) 2.
If it is determined to be 4B, the above step S39.
Similarly to the above, the image pickup OK determination is executed to check whether or not the recording medium (memory) 22 has a free space for storing the image data file (step S44). Then, when it is determined to be NG by the imaging OK determination, a warning to that effect is given by the image display unit 18 or the display unit 21 (step S45), and then the process proceeds to step S35.
On the other hand, when it is determined that the imaging is OK, imaging is performed and the image data file is stored in the current folder (folder B (Dss_fldb) 24B) (step S46). The file name of the image data file is automatically assigned. Then, the file name of the audio data file being recorded, the file name of the image data file, and the link number are written in the link data file (Fldb_lk.dat) 30B of the current folder (folder B (Dss_fldb) 24B). After that (step S47), the process proceeds to step S35.

In step S38, the current folder is the folder C (Dss_fldc) 2.
If it is determined to be 4C, since image pickup cannot be performed during recording, after that is warned by the image display unit 18 or the display unit 21 (step S48), the above step S35 is performed.
Proceed to.

Next, the "reproduction process" in step S17 described above.
The subroutine will be described. Here, in the "playback processing" subroutine, the current folder is the folder A (Ds
s_flda) 24A, folder B (Dss_fld)
b) The contents differ depending on whether it is the folder 24B or the folder C (Dss_fldc) 24C.

First, the subroutine of "reproduction processing" in the case where the current folder is the folder A (Dss_flda) 24A will be described with reference to FIG.

That is, when the "reproduction process" is called,
The reproduction of the audio data file 25 which is the current file in the current folder is started (step S71A).

Then, the current folder (folder A
By referring to the link data file (Flda_lk.dat) 30A of (Dss_flda) 24A), it is determined whether or not there is an image data file linked to the current reproduction position (step S72A).

If there is no linked image data file, it is next determined whether or not the fast-forward switch (FFSW) is turned on (step S73A).
If the fast-forward switch (FFSW) is not turned on, the fast-return switch (REWS)
It is determined whether or not (W) is turned on (step S74A). If the rewind switch (REWSW) is not turned on, the shooting switch (RESWSW)
It is determined whether or not the LSW) is turned on (step S75A). And this shooting switch (RELS
If W) is not turned on, it is further determined whether or not the stop switch (STOPSW) is turned on (step S76A). This stop switch (ST
If the OPSW) is not turned on, it is further determined whether or not the audio data file being reproduced has been reproduced up to the end (step S77A). Here, when the end of the audio data file has not been reached yet, the process returns to step S72A to continue the reproduction.

If it is determined in step S76A that the stop switch (STOPSW) has been turned on, or if it is determined in step S77A that the audio data file has been played to the end, the audio data file is played back. Is stopped (step S78A), and the "reproduction processing" subroutine is terminated.

On the other hand, when it is determined in step S72A that there is a linked image data file, the linked image data file is displayed on the image display section 18 (step S79A). The linked image data file may be displayed for a predetermined time, or may be displayed until the next linked image data file is displayed.

On the other hand, when it is determined in step S73A that the fast-forward switch (FFSW) is turned on, if there is the next linked image data file, the reproduction position of the audio data file is moved to that position, and the next If there is no linked image data file, normal fast-forward processing of the reproduction position is performed (step S80A). Similarly, when it is determined in step S74A that the rewind switch (REWSW) has been turned on, if there is a previously linked image data file, the playback position of the audio data file is moved to that position, and the previous link is performed. If there is no such image data file, the normal rewinding process of the reproduction position is performed (step S81A).

Further, according to the operation time of the fast-forward switch (FFSW) or the fast-return switch (REWSW),
You may change whether to move to the position where the image data file is linked or to perform the fast-forward / fast-reverse processing. For example, if the on-operation time of the fast-forward switch (FFSW) is shorter than a predetermined time, the image data file is moved to the linked position, and if it is longer than the predetermined time, normal fast-forward processing is performed, and the fast-reverse switch ( If the ON operation time of REWSW is shorter than the predetermined time, the previous image data file may be moved to the linked position, and if it is longer than the predetermined time, a normal fast-reverse process may be performed.

If it is determined in step S75A that the photographing switch (RELSW) has been turned on, it is checked whether or not there is enough free space in the recording medium (memory) 22 to store the image data file. A memory check is performed (step S82A).
If the result of the memory check is NG, the image display unit 18 or the display unit 21 gives a warning to that effect (step S83A), and then the above step S83.
Proceed to 76A. On the other hand, the memory check result is O
If it is K, the current position in the audio data file being reproduced is acquired (step S84A),
Imaging is performed and the image data file is stored in the current folder (folder A (Dss_flda) 24A) (step S85A). The file name of the image data file is automatically assigned. Then, the acquired current position, the file name of the image data file, and the file name of the audio data file being reproduced are set to the current folder (folder A (Dss_flda)).
24A) link data file (Flda_lk.d)
At) after writing to 30A (step S86A), the process proceeds to step S76A.

Next, with reference to FIG. 10, a subroutine of "reproduction processing" when the current folder is the folder B (Dss_fldb) 24B will be described.

That is, when the "reproduction process" is called,
Playback of the audio data file 25, which is the current file in the current folder, is started (step S71B).

Then, the current folder (folder B
The first of the image data files linked to the audio data file 25 is displayed on the image display unit 18 with reference to the link data file (Fldb_lk.dat) 30B of (Dss_fldb) 24B). If there is no image data file that has been linked, playback information (playback position, file length, file number, etc.) of the audio data file is displayed, and a message indicating that there is no linked image data is displayed. Step S72B).

Then, it is determined whether or not the reproduction switch (PLAYSW) is turned on (step S73).
B). When the reproduction switch (PLAYSW) is not turned on, the fast-forward switch (FFS) is further added.
It is determined whether or not (W) is turned on (step S74B). If the fast-forward switch (FFSW) is not turned on, it is further determined whether the fast-return switch (RESWW) is turned on (step S75B). This fast reverse switch (REWS
If W) is not turned on, it is further determined whether or not the photographing switch (RELSW) is turned on (step S76B). If the photographing switch (RELSW) is not turned on, it is further determined whether or not the stop switch (STOPSW) is turned on (step S77B). When the stop switch (STOPSW) is not turned on, it is further determined whether or not the audio data file being reproduced has been reproduced to the end (step S78B). here,
When the end of the audio data file is not reached yet, the process returns to step S73B, and the reproduction is continued.

If it is determined in step S77B that the stop switch (STOPSW) has been turned on, or if it is determined in step S78B that the audio data file has been played to the end, the audio data file is played back. Is stopped (step S79B), and the "reproduction processing" subroutine is terminated.

On the other hand, when it is determined in step S73B that the reproduction switch (PLAYSW) has been turned on, the link data file (Fl
db_lk. dat) 30B to display the next linked image data file on the image display unit 18 (note that if the displayed image data file is in the last order, the image data in the first order is displayed). Returning to the file, if there is no linked image data file, a warning (display and warning sound) that there is no linked image data is issued) (step S80B).

On the other hand, when it is determined in step S74B that the fast-forward switch (FFSW) has been turned on, the playback position of the audio data file being played back is fast-forwarded (step S81B).
When it is determined that the rewind switch (REWSW) has been turned on, the reproduction position is rewinded (step S).
82B).

If it is determined in step S76B that the photographing switch (RELSW) has been turned on, it is checked whether or not the recording medium (memory) 22 has enough free space to store the image data file. A memory check is performed (step S83B).
If the result of the memory check is NG, the image display unit 18 or the display unit 21 gives a warning to that effect (step S84B), and then the above step S84.
Proceed to 77B. On the other hand, the memory check result is O
If it is K, the image data is captured and the image data file is stored in the current folder (folder B (Dss_fldb)).
24B) (step S85B). The file name of the image data file is automatically assigned. Then, the file name of the audio data file being reproduced and the file name and link number of the image data file are set to the current folder (folder B (Dss_
Fldb) 24B) link data file (Fldb)
_Lk. dat) after writing to 30B (step S86
B), and proceeds to step S77B above.

Next, with reference to FIG. 11, a subroutine of "reproduction processing" when the current folder is the folder C (Dss_fldc) 24C will be described.

That is, when the "reproduction processing" is called,
First, it is determined whether the selected current file is the audio data file 25 or the image data file 26 (step S71C).

If the current file is the audio data file 25, the reproduction of the audio data file 25 is started (step S72C).

Then, it is determined whether or not the fast-forward switch (FFSW) is turned on (step S73).
C). When the fast-forward switch (FFSW) is not turned on, the fast-reverse switch (RE
It is determined whether or not the WSW) is turned on (step S74C). When the fast-reverse switch (REWSW) is not turned on, it is further determined whether or not the photographing switch (RELSW) is turned on (step S75C). And this shooting switch (R
When the ELSW) is not turned on, it is further determined whether or not the stop switch (STOPSW) is turned on (step S76C). When the stop switch (STOPSW) is not turned on, it is further determined whether or not the end of the audio data file being reproduced has been reproduced (step S77C). Where still
When the end of the audio data file has not been reached, the process returns to step S73C to continue the reproduction.

If it is determined in step S76C that the stop switch (STOPSW) has been turned on, or if it is determined in step S77C that the audio data file has been played to the end, the audio data file is played back. Is stopped (step S78C), and the "reproduction processing" subroutine is terminated.

On the other hand, if it is determined in step S73C that the fast-forward switch (FFSW) has been turned on, the playback position of the audio data file being played back is fast-forwarded (step S79C).
When it is determined at 74C that the fast-reverse switch (REWSW) has been turned on, the reproduction position is fast-returned (step S80C).

If it is determined in step S75C that the photographing switch (RELSW) is turned on, the image display unit 18 or the display unit 21 warns that photographing cannot be performed (step S81C). , And proceeds to step S76C above.

When it is determined in step S71C that the current file is the image data file 26, the image data file 26 is displayed on the image display section 18 (step S82C), and the "playback process" is displayed. Finish the subroutine.

Next, the "photographing process" in step S15 described above.
The subroutine will be described with reference to FIG.

That is, first, whether or not the recording medium (memory) 22 is mounted, whether or not it is formatted,
Memory check is performed to check if there is free space, etc.
It is determined whether or not it is K (step S51). If the memory check result is NG, the speaker 20
A warning to that effect is issued by the display unit 21 (step S5).
2) Then, the "photographing process" subroutine is ended.

On the other hand, the memory check result is OK.
, The current folder is the above folder A
(Dss_flda) 24A, folder B (Dss_fda)
1db) 24B, folder C (Dss_fldc) 24
It is determined which of the two is C (step S53).

If it is determined that the current folder is the folder A (Dss_flda) 24A, the current position in the audio data file which is the current file is acquired (step S54). That is, when the stop switch (STOPSW) is turned on during the reproduction of the audio data file in the "reproduction processing" subroutine, the reproduction is stopped at that position. The system control unit 16 holds this position, and the reproduction switch (P
When the "LAYSW" is turned on again, the reproduction is continued from that position. This step S
At 54, the stopped position is acquired as the current position.

After that, the image data is captured and the image data file is stored in the current folder (folder A (Dss_fl
da) 24A) (step S55). In addition,
The file name of the image data file is automatically assigned. Then, the acquired current position, the file name of the image data file, and the file name of the audio data file being reproduced are set as a link data file (Flda_lk.dat) 30A of the current folder (folder A (Dss_flda) 24A). (Step S56), the "photographing process" subroutine is terminated.

In step S53, the current folder is the folder B (Dss_fldb) 2.
If it is determined to be 4B, the image data is captured and the image data file is stored in the current folder (folder B (Dss
_Fldb) 24B) (step S57).
The file name of the image data file is automatically assigned. Then, the file name of the audio data file currently selected, the file name of the image data file, and the link number are set to the link data file (Fldb_lk.dat) 30B of the current folder (folder B (Dss_fldb) 24B). After writing (step S58), the "photographing process" subroutine is terminated.

In step S53, the current folder is the folder C (Dss_fldc) 2.
If it is determined to be 4C, the image data is captured and the image data file is stored in the current folder (folder C (Dss
_Fldc) 24C) (step S59).
At this time, the file name of the image data file is automatically assigned. Then, after the completion of this image capturing, the subroutine of the “image capturing process” is terminated.
