DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk reproducing apparatus and an audio apparatus, and more particularly to an optical disk reproducing apparatus and an audio apparatus suitable for automatically editing and recording a disk such as a CD, CDV, LD on a tape.

[0002]

2. Description of the Related Art For example, a CD player has conventionally been provided with an automatic editing function, and when a user wants to record on a tape from a CD, if the user sets an editing time corresponding to the one-sided recording time, the TOC information of the disk is referred to. , The editing music is stored in memory by automatically editing while selecting the music whose total playing time is within the editing time, and when the reproduction is instructed, the editing music is sequentially reproduced. As a result, it is possible to record from the CD to one side of the tape without the end of the music being cut off at the tape end. Specifically, in the automatic editing, the total playing time from the first song to the n-th song is included in the editing time, but the total playing time from the (n + 1) th song is edited. When the time is over, it is done by making up to the nth song an edited song.

[0003]

However, in the above-mentioned prior art, although a recording tape that faithfully follows the recording order of the disk is completed, when the (n + 1) th song is long, the total playing time up to the nth song is The difference in editing time may become large and a long empty part may remain at the end of one side of the tape. In addition, because automatic editing cannot be stopped midway, even if you set the editing time incorrectly, you cannot wait until the automatic editing is completed before you can perform another automatic editing based on the correct editing time. It was Further, during the automatic editing, it was not possible to know which song was edited and which song was not edited, and it was not possible to promptly determine whether or not the automatic editing should be redone. Also, after the automatic editing is completed, the user cannot confirm the song order of the automatically edited edited songs before starting recording, and the actual recording sequence can be known only by playing the recorded tape. I didn't.

On the other hand, in the case of recording from one CD on both sides A and B of the tape, the same song will be recorded on both sides A and B if one side is simply automatically edited and recorded. In this respect, the A side is automatically edited and recorded, and the B side is A
There is also a method of selecting and playing back a piece of music that enters the single-sided recording time other than the surface-edited piece, but this imposes a heavy burden on the user. With respect to this point, in the conventional CD player with an automatic editing function, when the editing time corresponding to the tape length is set, the set time is halved to the one-sided editing time, and
Editing in order from the first song, the total playing time from the first song to the nth song is within the A-side editing time, but (n + 1)
When the total playing time up to the tune exceeds the A-side editing time, the nth tune is regarded as the A-side edited tune, and similarly, (n +
1) Editing from the song in order, the total playing time from the (n + 1) th song to the (n + m) song is within the B side editing time, but the total playing time up to the (n + m + 1) song is the B side editing time. When the number of tracks exceeds the limit, some (n + 1) th to (n + m) th songs are B-side edited songs. Then, according to the reproduction command, the edited music pieces are sequentially reproduced one by one.

However, even in the above-described conventional double-sided automatic editing function, a long space may be formed at the end of the tape A side, and when recording on a used tape, the tape may be recorded at the end of the tape A side or B side. The original recording signal remained, which sometimes caused annoyance during playback. Furthermore, it was not possible to confirm which song was edited on the A side of the tape and which song was edited on the B side before the start of recording. The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide an optical disc reproducing apparatus and an audio apparatus in which the convenience of the automatic editing function is improved.

[0006]

DISCLOSURE OF THE INVENTION The present invention provides a reproducing means for reproducing an audio signal from a disc, an edit time setting means for setting an edit time, and a song recorded on the disc with reference to TOC information. The automatic edit means is provided with automatic edit means for automatically editing songs that enter the edit time while avoiding duplication, and playback control means for controlling the playback means in accordance with a playback command to play the edited songs in order. Each song is selected as an edit candidate song in turn order, and when the total playing time with the edited songs up to that time is within the edit time, this edit candidate song is regarded as the edit song that follows the edited song until the total play time When the number of songs exceeds the limit, the editing candidate song this time is not set as an editing song, but the next song is set as a new editing candidate song.

[0007]

According to the present invention, when the editing time is set, T
With reference to the OC information, the songs recorded on the disc which are in the editing time are automatically edited while avoiding duplication. At this time,
Each song is selected as an editing candidate song in the order of the song number on the disc, and when the total playing time with the editing songs up to that time is within the editing time, the editing candidate song this time is regarded as the editing song following the editing song until then, and the total playing time When the editing time is over, the edit candidate song this time is not set as the edit song, and the next song is set as the new edit candidate song. As a result, many songs can be automatically edited and recorded while keeping the disc recording order as faithful as possible, and the free time after recording can be reduced. Here, the program songs selected by the program are sequentially stored in the program song storage means, and when performing automatic editing, the program songs stored in the program song storage means are given priority as the editing candidate songs in the program song order, When there are no more editing candidates in the music storage means, the editing candidates are selected from the unprogrammed songs on the disc in the order of song numbers from the unedited songs. As a result, it is possible to surely record the desired music of the user while giving priority to it, and it is possible to reduce the free time after the recording.

When the edit time is set for each side of the tape, the TOC information is referenced to automatically select the songs that enter the edit time for each side of the tape from among the songs recorded on the disk, avoiding duplication. Edited at this time, for the first tape surface, one song is selected as an editing candidate song in the order of the song number of the disc, and the total playing time up to that time is within the editing time for the first tape surface. At this time, the edit candidate song of this time is edited after the previous edit song, and when the total playing time exceeds the edit time, the edit candidate song of this time is not edited and the next song is changed to a new edit candidate song. When editing the tape surface of the second and subsequent tapes, one of the unedited songs on the disc is selected as an edit candidate song in the song number order, and the edited songs of the second and subsequent tape surfaces are edited. And the total playing time is within the editing time for the recording area. When this time's edit candidate song is edited after the previous edit song and the total playing time exceeds the edit time, this edit candidate song is not edited and the next unedited song is changed to a new edit candidate. Let it be a song. As a result, even when automatically editing and recording on each side of the tape, it is possible to automatically edit and record many songs while preserving the recording order of the disk as faithfully as possible, and free space after recording on each side of the tape You can save time.

Also in this case, the program songs selected by the program are sequentially stored in the program song storage means, and when the respective sides of the tape are automatically edited, the program songs stored in the program song storage means are preferentially programmed. If the edit candidate songs are arranged in the order of songs, and if the program candidate storage unit has no edit candidate songs, it is possible to select the edit candidate songs in the order of the song numbers from among the unprogrammed songs on the disc. Can be reliably recorded while giving priority to the first tape surface, and moreover, the free time after recording on each tape surface can be reduced. If one set time is divided and the edit time is set for each tape surface, it is possible to save the trouble of separately setting the edit time for each tape surface.

Further, when the editing time is set, the songs which enter the editing time among the songs recorded on the disc with reference to the TOC information are automatically edited while avoiding duplication. One of the unedited candidate songs is the candidate song for editing, and when the total playing time with the previously edited song is within the editing time, this candidate song is considered as an edited song that follows the previously edited song. , When the total playing time exceeds the edit time, the edit candidate song of this time is not set as an edit song, and the edit song until then, or the edit song until then and the current edit candidate song Display the song number. At this time, in advance
It is also possible to prioritize the songs selected by the program as editing candidates. As a result, it is possible to quickly know which song has been edited during the automatic editing, and it is possible to quickly determine whether or not the automatic editing should be redone.

When an instruction to stop the automatic editing is given during the automatic editing, the editing operation is stopped. Thus, for example, when the editing time is set incorrectly, it is possible to promptly perform another automatic editing by changing the editing time or giving priority to a desired song without waiting for the automatic editing to be completed. Also, when the editing time for each side of the tape is set,
Among the songs recorded on the disc with reference to the TOC information, the songs which enter the editing time for each side of the tape are automatically edited while avoiding duplication, and the editing result is displayed for each side of the tape. Then, the reproduction means is controlled in accordance with the reproduction instruction to sequentially reproduce the edited music piece on each side of the tape. In this case, one set time may be divided and the edit time may be set for each surface of the tape. This allows you to easily record the music recorded on the disc on each side of the tape while avoiding duplication and at the end of the tape so that the music is not interrupted. You can check at a glance which song was edited.

When the editing result check is instructed after the automatic editing, the song numbers of the edited songs are displayed in the order of editing. As a result, it is possible to confirm which song was edited in which order before the start of recording.

Further, when the check of the editing result is instructed after the automatic editing, the song numbers of the edited songs are additionally displayed in the order of editing.
As a result, it is possible to confirm which song was edited in which order before the start of recording, and moreover, finally, all edited songs can be confirmed at a glance.

Further, by setting the edit time for each side of the tape, among the songs recorded on the disk with reference to the TOC information, the songs which enter the edit time for each side of the tape are automatically edited while avoiding duplication. After that, when the editing result check is instructed, the song number of the edited song is displayed for each side of the tape. And
The reproducing means is controlled in accordance with the reproducing command to sequentially reproduce the edited music piece on each side of the tape. Also in this case, one set time may be divided and the edit time may be set for each surface of the tape. This also makes it possible to confirm at a glance which song has been edited on each side of the tape before starting recording.

Further, in an audio device including an optical disk reproducing device and a recording device, the optical disk reproducing device refers to the TOC information when the editing time for each of the tapes A and B is set, and the optical disk reproducing device records the music recorded on the disk. From the inside, the songs that enter the editing time for each of the tapes A and B are automatically edited while avoiding duplication, and the playback means is controlled based on the first playback command to edit the songs on the tape A side (or tape B side). After being sequentially reproduced, the paused state or the stopped state is set, and the reproducing means is controlled based on the second reproduction command to sequentially reproduce the edited music piece on the tape B side (or the tape A side) and then the paused state or the stopped state. The recording device records the audio signal output from the optical disc reproducing device to the end of the tape A side (or the tape B side) based on the recording command,
When the recording to the end of the tape A side (or the tape B side) is completed, the recording is automatically started from the beginning of the tape B side (or the tape A side), and a reproduction command is issued to the reproduction control means of the optical disk reproducing device. give.

Thus, the tape A surface (or the tape B)
After recording the edited music from the disc, the silent part can be formed on the remaining part of the tape A side (or the tape B side), so that the tape A side is affected by an offensive sound. Never. Further, after the recording on the tape A side (or the tape B side) is finished, the user performs an operation to change the recording target to the tape B side (or the tape A side) one by one, and an operation to give a recording command and a reproduction command. You don't have to.

In this case, when the recording is instructed, the recording means determines that the recording instruction is given and the tape A side (tape B side).
If the reproduction command is given to the reproduction control means of the optical disk reproducing device at the same time when the recording is started, the edited music is recorded on the tape A surface (tape B surface) without the operation of giving the reproduction command. Can be made.

Further, if one set time set by the user is divided into the edit time for each of the tapes A and B, it is possible to save the user the trouble of setting the edit time separately for the tapes A and B.

Next, the operation of the above-described embodiment will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG. 9 and the explanatory views of FIGS. 2 to 18 show the operation of the system microcomputer 18 of the CD player 10, FIG. 19 shows the operation of the system microcomputer 60 of the tape recorder 50, and FIG.
0 to 28 show the display states of the display unit 22 of the CD player 10. First CD player 10 and tape recorder 50
It is assumed that the CD disk and the cassette 58 have been taken out. First, when a CD disc containing 10 songs is inserted into the CD player 10, the system microcomputer 1
After determining in step 70 of FIG. 2 that the CD has been inserted, the player 8 controls the respective parts of the CD player by PLAY, and stores the TOC information read by the signal processing circuit 14 in the RAM (step 72).

Subsequently, the system microcomputer 18 sends the song number y (y
(1 to 10), the performance time per song is registered as t (y), and the maximum song number "10" is registered as Y (step 74). Here, t (1) = 4 minutes 37 seconds t (6) = 5 minutes 02 seconds t (2) = 5 minutes 19 seconds t (7) = 4 minutes 24 seconds t (3) = 4 minutes 46 seconds t ( 8) = 4 minutes 05 seconds t (4) = 3 minutes 50 seconds t (9) = 5 minutes 23 seconds t (5) = 4 minutes 48 seconds t (10) = 4 minutes 27 seconds. Then, the track mode for normal performance is set (step 76).

At this time, the system microcomputer 18 has the display unit 2
21 is subjected to a predetermined display control to bring the display state of (1) of FIG. 21, and "1" to "10" of the calendar display 24 are turned on to indicate that all 10 songs are in the unplayed state, "1" is displayed on the character display 34, and the fixed character display 36 of <TRACK NO.> Is also turned on to indicate that the music piece number "1" is ready for performance. In addition, the character display 26 displays “0
"Minute 0 seconds" is displayed and the fixed character displays 30 and 28 of <SINGL> and <TIME> are also turned on to indicate that the elapsed playing time of one song is still zero. Further, the fixed character display 38 of <TRACK> is turned on to indicate that the track mode is currently set.

In this state, the system microcomputer 18 waits for a key input by the user, and when the PLAY key is turned on, the PLAY control of each part of the CD player is performed, and the music numbers "1" to "10" are sequentially played ( Step 7
8, 80). The user does not turn on the PLAY key, and TR /
When the PR key is turned on to select a program, the mode is switched to the program mode (steps 82 and 8).
4), after initializing e to 1, wait for a music selection operation using the ten keys (steps 86, 88). For example, when the user selects song numbers “1”, “6”, “4”, and “5” in that order, first, when the song number 1 is input, the system microcomputer 18 determines YES in step 88, and “1” is given. Is RAM
After confirming that it is not yet registered in the program file of, then register as P (e) = P (1) = “1”, then e is incremented (steps 90 to 96),
Return to step 88. Similarly, every time the next song number is designated, P (2) = “6”, P (3) = “4”, P
(4) = “5” is registered in the program file. In step 88, only the songs selected from "1" to "Y" are valid.

As a result, under the display control of the system microcomputer 18, the display state of the display section 22 becomes as shown in (1) of FIG. 23, and the calendar display is "1", "4", "5", "6".
Is displayed, the character display 34 displays the song number “1” of the first program song, and the character display 26 displays the total playing time of all program songs including the space of 4 seconds between songs. , <TOTAL>, <TIME> fixed character display 32, 2
8 and <-> fixed character display 27 are also turned on. Furthermore, <PGM> and <AUTO-S.> Fixed character displays 40 and 4
4 is lit to indicate that the program mode is in effect and that the space between songs is automatically set to 4 seconds during performance. If the user turns on the PLAY key in this state,
The system microcomputer 18 refers to the program file in the RAM and plays the music in the order of user's selection of music (see FIG. 3).
Steps 98-102).

In contrast to this, when the user wants to automatically edit and record from the CD disc to both sides A and B of the 45-minute tape, the EDIT key is turned on after inserting the CD disc. The system microcomputer 18 reads the TOC information and sets the track mode immediately after inserting the CD disc (steps 70 to 76 in FIG. 2), and when the EDIT key is turned on, determines YES in step 104, and proceeds to the flow in FIG. First, the program mode and the edit mode are set (step 106). At this time, the display state of the display unit 22 under the control of the system microcomputer 18 is (2) in FIG.
As described above, <PGM> and <AUTO-S.> Are turned on as described above, and the fixed character display 42 of <EDIT> is turned on to indicate that the edit mode is set. The upper two digits of the character display 26 are displayed as <--->, indicating that the time input is waiting.

After the processing of step 106, the system microcomputer 18 clears E and waits for the editing time input by the user (steps 108 and 110). If the user first turns on the “40” key on the numeric keypad within 5 seconds, the system microcomputer 18 indicates that the input in 10-minute units is “4”.
It is registered in M and displayed at the fourth digit of the character display 26 (step 112, see (3) in FIG. 20). Subsequently, when the user turns on the “6” key of the ten-key within 5 seconds again, the system microcomputer 18 registers in the RAM that the minute unit is “6” and displays it in the third digit of the character display 26 ( Steps 110 and 112, see (4) of FIG. 20). 1
If there is no change operation within a predetermined time (for example, 3 seconds) after inputting time in units of 0 minutes and minutes, the system microcomputer 18 registers 46 minutes as the editing time W as the completion of time input (step 114, 116). In addition,
In this embodiment, the editing time input by the user is divided into two parts on the system microcomputer 18 side and allocated to the editing times of the A side and the B side.

Subsequently, the system microcomputer 18 displays the display section 22.
The fixed character display 42 of <EDIT> is blinked to notify the user that the automatic editing process has been started (step 118), and the character displays 34 and 26 are used to <A FIL.
E> is displayed to indicate that the tape A side is being edited (step 120, see (5) in FIG. 20). Here, the system microcomputer 18 once turns off all the calendar displays (step 122), and after confirming that E is 0 and that no program has been selected in advance (step 12).
4), the total playing time data ΣT _A of the A side is cleared, and l and y are set to 1 for initialization (step 12).
6, 128).

Next, the system microcomputer 18 lights up "1" on the calendar display 24 to indicate that the music number "1" is being processed (step 130 in FIG. 5). Since l is 1, Σ
Only the playing time t (1) of the music piece number "1" is added to T _A to obtain a new ΣT _A, and it is determined whether or not this is within W / 2 = 23 minutes (steps 132 to 136). Since t (1) is 4 minutes 37 seconds, which is less than 23 minutes, the system microcomputer 18 determines YES in step 136, and stores A (1) in the A file.
= "1" is registered (step 138). As a result, the music of the music number "1" is recorded as the first music of the A side. Subsequently, the system microcomputer 18 increments l (step 140), confirms that y is not 10 yet (step 142), increments y (step 144), and returns to step 130. As a result, "2" is added to the calendar display.

At this time, the music number "1" remains displayed in the calendar, indicating that it has been registered in the A file (see (6) in FIG. 20). Now since l ≠ 1, the system microcomputer 18 as a new oT _A plus 4 seconds of playing time t (2) = 5 minutes 19 seconds and passages in space Kyokuban "2" oT _A (step 132, 146), 2
It is determined whether the time is 3 minutes or less (step 136). Still 23
Since it is less than the amount, the system microcomputer 18 registers the music number "2" as A (2) (step 138), increments l and y (steps 140 to 144), and then returns to step 130. In the same way, song number “3”,
For "4" as well, the total performance time including the space between songs does not exceed 23 minutes, so A (3), A
Register as (4) (steps 132, 146,
Repeat 136 to 144, see (7) and (8) of FIG. 20).

The song number "5" is once added to the calendar display in the process of step 130 (see (1) in FIG. 21), but the total playing time is 23 minutes and 36 seconds, which is 23.
If you add it to A file as it is, it will be cut off when recording. System microcomputer 1 here
8 determines NO in step 136, turns off "5" in the calendar display without registering it in the A file, and subtracts t (5) and 4 seconds from ΣT _A to restore the original value. (Step 148). Then, since y is not 10, the process proceeds to the step 144 side, and the same processing is performed for the music number "6" and thereafter. Since the total playing time of the song numbers "6" and "7" exceeds 23 minutes, it is not registered in the A file (steps 130, 132, 146, 136, 148, 14).
2, 144, (2) and (3) in FIG. 21).

For the song number "8", the playing time is short, and the total playing time after adding to the calendar display is 22 minutes 53 seconds, which is slightly less than 23 minutes, so the system microcomputer 18 sets A (5) = It is registered in the A file as "8" (steps 130, 132, 146, 136-14).
4, see (4) in FIG. 21). Next song number "9" and "10"
With respect to each of the above, the system microcomputer 18 determines NO in step 136, and the song numbers “9” and “10” on the calendar display that have been turned on once are turned off ((5) to (() in FIG. 12). 7)). Then, after the processing of step 148 for the last song number “10” is completed,
The system microcomputer 18 determines YES in the next step 142.

At this time, after confirming that l is not 1 but one or more songs are registered in the A file (step 150),
l-1 is calculated and registered as the number L of pieces of music in the A file (step 152 in FIG. 6), and from 23 minutes onward, ΣT _A
Is calculated and the result is displayed on the character display 26 as the remaining editing time (steps 154, 156, FIG. 2).
1 (8)). At this time, <-> fixed character display 2
7 is also turned on. After 3 seconds, the system microcomputer 18 causes the character displays 34 and 26 to display <b.
FILE> is displayed to indicate that editing of the B side of the tape has started (steps 158 and 160), FIG.
(1)). Then, the system microcomputer 18 turns off all the calendar displays (step 162), clears the total performance time data ΣT _B on the B side, sets m and y to 1 and performs initialization (steps 164 and 166).

Next, the system microcomputer 18 determines whether or not the music number indicated by y has been registered in the A file (step 16).
8). Song number "1" is already registered for Side A, so
The system microcomputer 18 determines YES in step 168, moves to the flow of FIG. 7 without registering in the B file, confirms that y is not 10, and increments (steps 170 and 172), and then in step 168 of FIG. Return to judgment. Similarly, since the song numbers "2" to "4" have already been registered in the A file, the system microcomputer 18 does not register them in the B file (steps 168, 170 and 172 are repeated). If y becomes 5, it is not registered in the A file, so the system microcomputer 18 returns NO in step 168.
Judge.

At this time, the system microcomputer 18 displays "5" on the calendar (step 174, see (1) in FIG. 22). Since m is 1, the playing time t of the song number "5" is added to ΣT _B.
(5) = 4 minutes and 48 seconds is added to make a new ΣT _B, and it is determined whether or not this is 23 minutes or less (steps 176 and 17).
8, 180). Since the determination here is YES, the music piece number "5" is registered as the first music piece B (1) of the B file, m and y are incremented, and the process returns to step 168 (steps 182, 184, 170, 172). The calendar display "5" remains lit. Since the song number “6” indicated by y is not registered in the A file, the system microcomputer 18 adds “6” to the calendar display (step 17
4, (2) of FIG. 22), this time m ≠ 1 and ΣT _B is added to the playing time of the song number “6” and the inter-spacing space of 4 seconds, and it is determined whether the time is 23 minutes or less (steps 176, 186). , 18
0).

Since the answer is YES here, the system microcomputer 18 also registers the song number "6" in the B file as B (2) and continues to turn on the calendar display "6" (step 182, (3) in FIG. 22). reference). The system microcomputer 18 registers B (3) in the B file in the same manner for the song number "7" (steps 184, 170,
172, 168, 174, 176, 186, 180, 1
82, refer to (4) in FIG. 22), and the music piece number “8” has already been registered in the A file, so it is not registered in the B file (determination of YES in steps 184, 170, 172, 168). The next song number "9" is not in the A file, and the total playing time (including the space between songs) including this is 19 minutes 49 seconds, which is less than 23 minutes, so it is registered as B (4). Add to calendar display (steps 170, 17)
NO judgment at 2, 168, 174, 176, 186, 1
80, 182, (4) and (5) in FIG. 22).

The song number "10" is not in the A file and the system microcomputer 18 judges NO in step 168 and once displays the calendar, but the total playing time of the B side including the song number "10" is 24 minutes. It takes more than 23 minutes in 20 seconds, so I do not register and the calendar display is erased and ΣT _B is t
(10) and return to a value that does not add 4 seconds (step 174,
176, 186, 180, 188, (5) in FIG.
(6)). Here, y is 10, and the selection of whether or not all the songs on the CD disc should be edited on the B side is completed, so the system microcomputer 18 proceeds to Y at step 170.
ES is determined, m-1 is calculated to be the total number M of songs in the B file, and a value obtained by subtracting ΣT _B from 23 minutes is displayed on the character display 26 as the B-side editing remaining time (step 190 in FIG. 8). ˜194, see (7) of FIG. 22). At this time <-
The fixed character display 27 of> is also turned on.

After 3 seconds, the total time of ΣT _A and ΣT _B is obtained, and the total playing time of the A and B planes is displayed on the character display 26 (steps 196 to 200, see (8) in FIG. 22). . At this time, the fixed character indicators 32 and 28 for <TOTAL> and <TIME> are also turned on, and the calendar indicator 24
Also displays all song numbers in the A and B files.
Also, the character display 34 displays the music number "1" relating to A (1), and <TRACK NO.> Is also turned on. Furthermore <EDIT>
Is changed to a continuous lighting state (step 200). As a result, the A side and the B side are automatically edited without the duplication of music in the editing time of 23 minutes each. The song numbers registered for the A side are "1", "2", "3", in the file order.
“4” and “8”, and the music numbers registered for the B side are “5”, “6”, “7”, and “9” in the file order. As will be described later, during reproduction, recording is performed on the A and B sides of the tape in the above order.

It should be noted that the edit mode can be canceled by not performing a time input operation at all from the time the user turns on the EDIT key until the time input is completed, or by interrupting the time input operation (see FIG. 4). Step 202
Then, the determination is YES, 204). At this time, <EDIT> is erased and the normal program mode state is entered (shift to step 86 in FIG. 2). In addition, after the time input is completed and the automatic editing is started, the automatic editing can be stopped and the edit mode can be canceled at any time by pressing the STOP key until <EDIT> changes to the continuous lighting state. Step 206 of FIG. 5, step 208 of FIG. 6, or steps 210 and 208 of FIG. 6, or step 2 of FIG.
12, 208, or steps 214, 208 of FIG. 8).

At this time, the system microcomputer 18 displays <EDIT>.
Is turned off, and all of the A, B, A ', B'files and program files are cleared (step 216 in FIG. 6),
Use the character displays 34 and 26 to set <no FILE> to 3
It is displayed for a second (step 218, see FIG. 27). After that, the normal program mode is set (step 86 in FIG. 2).
To). Therefore, if you notice that you have made a mistake in setting the editing time after turning on the EDIT key but before the automatic editing is completed, you can immediately perform a new automatic editing operation without waiting until the automatic editing is completed. It is possible to shorten the time required to execute the automatic editing that satisfies the desired condition.

Separately, as a result of automatic editing of the A side, even if no song is found in the A side editing time, the system microcomputer 18 determines YES in step 150 of FIG. Since it shifts to the side, the automatic editing process is immediately stopped. Therefore, by turning on the EDIT key again and inputting the time again, new automatic editing can be restarted promptly.

By the way, when the user wants to preferentially record the songs of the song numbers "1", "4", "5" and "6" in the CD disc onto the tape, the program is selected in advance under the normal program mode. Then press the EDIT key. For example, if the song numbers “1”, “6”, “4”, and “5” are selected in this order, they are registered as P (1) to P (4) in the program file. At this time, the display state is as shown in (1) of FIG. Next, when the user turns on the EDIT key, the system microcomputer 18 determines YES in step 300 of FIG. 2, registers e-1 as E, and then sets the edit mode (steps 302 and 304). Then, the process moves to the flow of FIG. 4 and waits for the time input by the user. At this time, the calendar display is not turned off yet (see (2) in FIG. 23).

46 minutes for user to record on tape for 45 minutes
After setting the time for minutes, the system microcomputer 18 starts automatic editing of side A after registering it as W (step 1
10-122, (3) and (4) in FIG. 23). Since E is not 0 this time and the user-desired song is programmed in advance, NO is determined in step 124, and the flow proceeds to FIG. 9. And first of all, A and B are selected from the program selected
Select face edit candidates. The sub total playing time data ΣT _A ′ related to the A side is cleared, and n and e are both set to 1 for initialization (steps 306 and 308). Since n is 1, ΣT _A only for the playing time of the first program song. It is judged whether the value added to ´ is 23 minutes or less. In this case, it is YES, so A
The file is registered as A '(1) = "1" in the file (steps 310 to 316). Subsequently, the system microcomputer 18 increments n and e and returns to step 310 (steps 318 to 322).

Since n ≠ 1 this time, the system microcomputer 18
In addition the playing time and passages in the space 4 seconds for the second program song "6" to the oT _A ', determines whether 23 minutes or less (step 324,314). Since it is also YES here, the system microcomputer 18 registers as A '(2) (step 316). Similarly, for the third and fourth program songs “4” and “5”, the sub total playing time considering the space between songs is 23 minutes or less, so A ′ (3) = “4”, A
Register as' (4) = “5”. Here, e = 4, and after the system microcomputer 18 determines YES in step 320, this time the sub total playing time ΣT _B related to the B side.
'Is cleared, r and e are set to 1, and initialization is performed (Fig. 1
0, steps 326-330), if P (1) is not in the A'file, it is registered in the B'file in the same manner as described above (steps 332, 400-406).

Since all the program songs have been registered in the A'file here, the system microcomputer 18 does not perform the registration process for the B'file (steps 332, 3).
34, 336). Finally, when e becomes 4 and YES is determined in step 334, the system microcomputer 18 shifts to the flow of FIG. 11 and rewrites ΣT _A with the sub total playing time ΣT _A ′ regarding all registered songs in the A ′ file (step 338). Then, the system microcomputer 18 sets 1 and y to 1 (step 340), displays the music number "1" once in the calendar to indicate that the process is being performed (step 342), and then performs the music number in the same manner as described above. It is determined whether "1" is included in the A'file (step 344).

Since the music number "1" is included in the A'file, the system microcomputer 18 sets A (1) = "1" to A.
It is registered in the file and the calendar display is continued (step 346, see (4) and (5) in FIG. 23). Then l
And y are incremented (steps 348, 350, 3
52), the music piece number "2" is once displayed on the calendar (step 342, see (5) in FIG. 23). Since "2" is not in the A'file, the system microcomputer 18 adds the playing time of the music number "2" and 4 seconds to ΣT _A , and determines whether it is 23 minutes or less (steps 344 and 354). Since the total playing time of all the songs in the A'file and the song number "2" is 23 minutes 42 seconds, it is judged NO in step 356, the "2" on the calendar display is erased, and at the same time, the song number "ΣT _A " The playing time of 2 "and the value not adding 4 seconds are returned (step 358).

The system microcomputer 1 for the song number "3"
8 once displays the calendar (steps 352, 342,
As shown in (6) of FIG. 23), since it is not in the A ′ file, it is determined whether the value obtained by adding the playing time of the music number “3” and 4 seconds to ΣT _A is 23 minutes or less. Again, it has been over 23 minutes, the system microcomputer 18 erases the "3" on the calendar display, and ΣT _A
(Steps 344, 354-358, FIG. 23).
(See (7)). Since the song numbers “4”, “5”, and “6” are in the A ′ file, they are A (2) to A as they are.
It is registered as (4) and added to the calendar display (steps 352, 342 to 348 are repeated, (7) and (8) in FIG. 23, and (1) in FIG. 24).

Similarly, although the song number "7" is not in the A'file, ΣT _A including this playing time is 22 minutes 57 seconds and is within 23 minutes, so it is registered as A (5) and the song number "8" , “9”, and “10” are not in the A ′ file, and the total playing time exceeds 23 minutes, the system microcomputer 18 does not register them in the A file, and also erases the once-lit calendar display (see FIG. 24). (2) to (7)). And y =
When it becomes 10 and the processing for the music number "10" is finished, the system microcomputer 18 judges YES in step 350, and l
Let -1 = 5 be the number of tunes in the A file (step 360 in FIG. 12), and display a value obtained by subtracting the total playing time ΣT _A of the A side from the editing time of 23 minutes for 3 seconds as the remaining editing time (step). 362 to 366, see (8) of FIG. 24).

Next, the system microcomputer 18 sets <b FIL
After the E> display and the calendar display are all extinguished (steps 368 and 370, see (1) of FIG. 25), ΣT _B is rewritten with the total playing time ΣT _B ′ of the song in the _B ′ file (step 372). ). In this case, nothing is registered in the B'file, and ΣT _B is set to 0. Then, m and y are set to 1 (step 374), it is determined whether or not the B'file is empty (step 376), and here, YES.
Therefore, the process shifts to the step 168 side of FIG. 6, and similarly to the above, a song whose total playing time of the B side does not exceed 23 minutes is selected from the songs which are not registered in the A file and the B file is selected. I will register. As a result, song numbers are registered in the B file in the order of "2", "3", "8", "9" (see (2) to (7) in FIG. 25).

When the processing up to the song number "10" is completed, the system microcomputer 18 displays the remaining editing time on the B side for 3 seconds, and finally displays the total playing time and the edited song number for both the A and B sides. (Steps 192 to 2 in FIG. 8)
00, see (7) and (8) of FIG. 25). In addition, young B '
If there is a registered song in the file, the system microcomputer 18
Decides NO in step 376 of FIG. 12, and selects song number “y”
If the file is in the B'file, it is directly registered in the B file (steps 378 to 382, step 38 in FIG. 13).
4), A file and B'file do not exist, and ΣT _B
Even if the time obtained by adding 4 seconds to t (y) does not exceed 23 minutes, it is registered in the B file (steps 378 to 382, 38).
6, 388, 384).

In this way, for example, when the user wants to check the edited contents after the above-described automatic editing without program selection is completed, the check key of the operation unit 20 is turned on. Then, the system microcomputer 18 determines YES in step 500 of FIG. 14, and the fixed character display 4 of <PC> is displayed.
After 6 is turned on (step 502), 1 is first set to 1 (step 504), and <A-1> is displayed on the character display 26.
A (1) = "1" is displayed on the character display 34, and "1" on the calendar display 24 is turned on (step 50).
6, (1) in FIG. 26). This allows the user to know that the beginning of the A-side is the song with the song number “1”. 5 users
When the check key is turned on again within the second, the system microcomputer 18 increments 1 and confirms that the number of songs in the A file has not yet exceeded 5 (step 50).
8 to 514), the process returns to step 506 again, and this time, the second music number "2" on the A side is displayed. Similarly, every time the check key is turned on, the system microcomputer 1
8 sequentially displays the third and subsequent music numbers on the A side.

When l becomes 6 in the process of step 512, m is set to 1 this time (step 516), <b-1> is displayed on the character display 26 and B is displayed on the character display 34.
(1) = “5” is displayed, and the calendar display 24
"5" is turned on (step 518, (2) in FIG. 26).
reference). From this, the user knows that the beginning of the B-side is the song with the song number "5". When the user turns on the check key again within 5 seconds, the system microcomputer 18 increments m, confirms that the number of songs in the B file has not exceeded 4, and then returns to step 518 again.
The second song number "6" on the B side is displayed (step 520).
~ 525). Thereafter, each time the check key is turned on in the same manner, the third and subsequent music numbers on the B side are displayed. Then, when m becomes 5 in the process of step 525, step 5 is executed again.
Returning to 04, the edited tune concerning the A side is displayed. In this way, after the editing is completed, the check key is turned on to confirm the music numbers and the order edited for the A side and the B side. After confirmation, if the check key is left on for 5 seconds or more, <PC> disappears (step 526) and the process returns to step 200 in FIG.

Next, according to the editing result, when recording is to be performed on the tape, the tape is set in the tape recorder 50 in advance for 45 minutes. When the CD player 10 and the tape recorder 50 are not to be synchronized with each other, the REC key is first turned on while the tape recorder 50 is in the auto-reverse mode. Then, the system microcomputer 60 is urged by the ON operation of the REC key to perform the REC control on the tape running / mechanical portion to start the recording operation (steps 700 and 702 in FIG. 19). At this time RE
Since the synchro key of the operation unit 62 is not turned on at the same time as the C key, a mute on signal is output to the mute circuit 52 to start mute after recording is started (steps 704 and 706). After 4 seconds, a mute off signal is output to cancel the mute (steps 708 and 7).
10). As a result, a silent region of 4 seconds is formed at the beginning of surface A.

Here, the PLAY key of the CD player 10 is turned on. When the PLAY key is independently turned on, the system microcomputer 18 returns YES in step 528 of FIG.
After it is determined to be NO at 30, the flow proceeds to FIG. The first ON of the PLAY key is treated as an A file designation and a playback command, l is set to 1, and search control to the music number "1" indicated by A (1) is performed by referring to the A file. 14 and the servo mechanism section (steps 532 and 534). During the search, the system microcomputer 18 displays <A-1> on the character display 34, and the character display 34
"1" is displayed on the screen (step 536). When the search is completed, the system microcomputer 18 displays the remaining playing time of the A side on the character display 26 by referring to the A file and TOC information (steps 538 and 540).

Since the timer is not in operation, the system microcomputer 18 immediately executes the PLAY control to start the reproduction of the music piece number "1" (steps 542 and 546). PLA
During Y, the recording signal of the CD disc is detected by the optical pickup 12, and the signal processing circuit 14 reads the audio sample data and the subcode. The audio sample data is converted into an analog audio signal by the D / A converter 16 and output to the tape recorder 50 side via the audio line. On the tape recorder 50 side, a mute circuit 52, a recording amplifier 54, and a head 56 record the tape.

During PLAY, the system microcomputer 18 always inputs the sub-code from the signal processing circuit 14 to calculate and display the total remaining playing time of the A side (step 548). After that, when the performance of the song number "1" ends, the system microcomputer 1
8 starts the timer (steps 550, 55
2), 1 is incremented after deleting "1" on the calendar display, and since l has not exceeded 5 yet, the process returns to step 534 again (step 554, step 5 in FIG. 17).
56-558), the song number “2” related to the second of the A file
Search is started, and at this time, the display on the character display 26 is
The display on the character display 34 is changed to "2" in place of A-2> (step 536 in FIG. 16). When the search is completed, the system microcomputer 18 displays the total playing time of the remaining songs on the A side (steps 538 and 540). Then, it waits until the timer counts for 4 seconds (step 544), and when 4 seconds have elapsed, the PLAY of the music number "2" is started.

On the tape recorder side, when the recording of the music number "1" is finished, the recording of the music number "2" is started after the silent region of 4 seconds is formed. The presence of this silent region enables the tape recorder 50 side to search for music. In the same manner, the registered songs in the file A are reproduced in order, and when the last song number "8" is finished, the system microcomputer 18
After confirming that M is not 0 and there is a registered song for the B side, m is set to 1 and the beginning song number "5" of the B file is searched (YE at step 558 in FIG. 17).
Judgment of S, 560 to 564). During the search, the system microcomputer 18 causes the character display 26 to display <b-1>, and the character display 34 displays "5" (step 5).
66, (1) in FIG. 28).

When the search is completed, the system microcomputer 18 displays the total remaining playing time of the B side, then performs PAUSE control to temporarily stop the reproducing operation (steps 568-572, see (2) in FIG. 28). ). In this state, it waits until the PLAY key of the operation unit 20 is turned on (step 574). After the performance of the last piece of music for the A side is completed, the CD player 10 side becomes in a non-signal state, and the tape recorder 50 side forms a silent area after the recording of the music number "8" is completed. As a result, when the tape is recorded in advance, the unnecessary portion is automatically erased.

After that, when the tape end of the A side is reached,
The tape end detection unit 64 detects this and outputs a tape end detection signal. The system microcomputer 60 is urged by this detection signal and determines that the first tape end has occurred (steps 712 and 713 in FIG. 19), and since it is not in the auto reverse mode, it immediately stops the set parts.
Control and stop the recording operation (step 714,
716). Here, the user ejects the cassette 58, sets it on the opposite side, sets it again, and turns on the REC key. Then, the system microcomputer 60 returns to the REC as described above.
Control is performed to start recording, and mute is applied for the first 4 seconds (steps 700 to 710).

The user turns on the PLAY key of the CD player 10 4 seconds after the REC key is turned on. Then, the system microcomputer 18 returns Y in step 574 of FIG.
After judging ES, press the PLAY key for the second time on B
It is treated as a file playback command, and PAUSE is immediately released to start playing the song number "5" (step 578 in FIG. 18). Then, in the same manner as described above, each time the performance of one song ends, the corresponding song number on the calendar display is erased, and after searching for the song related to the next registered song number in the B file, there is a gap of 4 seconds between songs. PLAY (steps 580-60)
0, 578). In this way, the songs "5", "6", "7", and "9" are played in sequence.

At the end of the performance of the last music number "9", when m becomes 5 by the processing of step 588, P
LAY is stopped (steps 590 and 601). Correspondingly, on the side of the tape recorder 50, after the first silent area on the B side, the music numbers "5", "6", "7", and "9" are recorded in order. After the recording of the last song number "9" is completed, a silence area is formed, and the system microcomputer 60 stops recording at the tape end of the B side (Fig. 19).
712, 713, 716).

As described above, the CD player 10 side 1
When the PLAY key is turned on for the second time, the registered songs in the A file are played in sequence, and when all the performances in the A file are completed, the first song in the B file is searched, and then the PAUSE state is entered. After the last song is recorded, it automatically becomes a silent range, so you can save the trouble of erasing unnecessary parts even when using a used tape, and
When the tape end of the A side is reached, the direction of the cassette 58 is changed, and the recording is started. Then, when the PLAY key is turned on for the second time on the CD player 10, the songs in the B file are played in order, and the A side is played. It is not necessary to perform a STOP operation on the side of the CD player 10 at the time when the performance is changed to the song on the B side, and moreover, the recording as edited can be easily and surely performed.

If the CD player 10 and the tape recorder 50 are desired to be synchronously controlled, the cassette 58 is inserted in advance and the tape is rewound to the leading position of the A side, and the auto reverse setting key is turned on to set the auto reverse mode. I'll do it. In this state, first, the PLAY key and the synchro key on the CD player 10 side are simultaneously turned on. Then, the system microcomputer 18 determines YES in both steps 528 and 530 of FIG. 15, and then performs the search control of the first music piece of the A file, and automatically enters the PAUSE state after the search is completed, and starts the PLAY from the tape recorder 50. Wait for signal input (steps 602-612).

Next, on the tape recorder 50 side, the REC key and the synchro key are simultaneously turned on in the same manner. Then, the system microcomputer 60 starts recording (see FIG. 1).
Steps 700 and 702 of 9), confirm that the synchro keys are turned on at the same time, and this time perform mute control for 4 seconds and then P
The LAY start signal is output to the CD player 10 side (steps 704, 720 to 726). The CD player 10 side is energized by the input of the PLAY start signal and step 5 in FIG.
It suffices to execute the same processing as that of S46 and thereafter to start the performance from the first music piece of the A file. However, during synchronous control,
Instead of the processing of step 574 of 7, it is determined whether or not there is a PLAY start signal input.

When the performance of the last music number "8" of the A file is completed, the CD player 10 enters the PAUSE state, and a silent area is formed on the rest of the tape A side (see step 572 in FIG. 17). And when it comes to the tape end of side A, the system microcomputer 60 is the first tape end,
At the same time, confirm that the auto reverse mode is set and perform the auto reverse (step 7 in FIG. 19).
28-732). Then, the process proceeds to step 720, and after the mute control for 4 seconds, the PLAY start signal is output again.

C is activated by the input of this PLAY start signal.
On the D player 10 side, the performance is restarted from the first song of the B file. When the last song of the B file is finished playing, the CD player 10 stops PLAY (see steps 590 and 601 in FIG. 18), and when the tape end of the B side is reached thereafter, the tape recorder 50 stops recording (step). 728, 729, 734). In this way, by performing the synchronous control between the CD player 10 and the tape recorder 50, the user only has to first perform the PLAY operation and the REC operation, and after that, even if the user separates from the audio device, A, A Since both sides of B can be recorded, the operation becomes easier.

According to this embodiment, the user can turn on the edit key and simply enter the time corresponding to the length of the tape in the cassette, so that the music pieces which do not overlap with each other on both sides A and B of the tape can be recorded. Can be edited, and the user does not have to perform the troublesome work of selecting a program while calculating the playing time for each face.
