reference). The ROM of the system microcomputer 14 stores the maximum allowable program number PM (here, 20) of the program file area (see (1) in FIG. 2).

Next, the operation of the above embodiment will be described with reference to FIGS.
, An explanatory diagram of the program file shown in FIG. 9, and an explanatory diagram of the display state shown in FIG. First, when a CD disk containing, for example, 15 songs is inserted into a CD player, the system microcomputer 14 determines in step 200 in FIG. 3 that a CD has been inserted, and then performs PLAY control of each part of the CD player. The stored TOC information is stored in the RAM (step 202). Then, referring to the TOC information, the minimum track number of the CD disk is NI, the maximum track number is NM, and the track number y (y = y
(NI to NM) is registered in the RAM as t (y) (step 204). Here, NI
= 1, NM = 15. Then, a track mode (normal mode) for normal performance is set (step 2).
06).

At this time, the system microcomputer 14 operates the display unit 1
A predetermined display control is performed on the M.8, and "1" to "15" of the music calendar display 22 are turned on to indicate that all of the 15 songs have not been played yet. NO indicator 26
Displays <1>, indicating that the music number "1" is in a performance preparation state. Also, <0 minute 0 second> is displayed on the time display 24 to indicate that the performance elapsed time of the music number 1 is still zero. In this state, the system microcomputer 14 waits for a key operation by the user. If you want to start playing,
When the PLAY key is turned on, the system microcomputer 14 is in a CD.
The PLAY control of each part of the player is performed, and the music numbers "1" to "15" are sequentially played (steps 400 to 40).
6). When the performance is over, stop control is performed (step 40).
8).

[0017] The favorite piece of music program unlike this, among users of CD disk, when you want to program performance of a particular favorite piece of music, first of all, to turn on the PROG key. Then, the system microcomputer 14 sets the program mode (steps 208 and 210. At this time, the music calendar display 22 is turned off. Also, the T.NO display 26 is <->, and the P.NO display 28 is <1>, the time display 24 is <-::->
Is displayed. ), Clear all contents of the program file area of the RAM (step 212), and set PN to 1
T is initialized to 0 (steps 214 and 216). Further, the flags CF and PF are cleared, and the program check number PN 'is set to 0 (step 218). The program file must be cleared for each program number.
This is performed by writing hyphen data "-" in both the tens place and the ones place as the music number data (two digits).

Next, when the user inputs, for example, a song number 1 as a desired song by using a numerical key, the system microcomputer 14 determines YES in step 220 of FIG. 4 and the input song number falls within the range of NI to NM. After confirming that the input music number is N (steps 222 and 224), the current PN = 1 is the maximum allowable number PM = 20 of the program number.
Does not exceed (NO in step 226), CF
Is confirmed (NO in Step 228), N = 1 is written and registered in the program file as the music number corresponding to the program number PN = 1 (Step 230). In addition, the playing time t of track number 1 is
(1) is added to obtain a new ΔT (step 23)
2).

Then, the system microcomputer 14 sets N = 1.
To T. NO display 26, PN = 1 is set to P.N. NO
It is displayed on the display 28, "1" is lit on the music calendar display 22, and the value of ΔT is displayed on the time display 24 (step 234). And
After setting the timer to start timing (step 2
36), PN is incremented to 2 (step 238). When the timer starts the time counting operation, the system microcomputer 14 determines YES in step 240 of FIG. At this time, it is determined whether or not the time counted by the timer has elapsed 5 seconds, and if not, the display state is not changed (NO at step 242).

When five seconds have elapsed without the user inputting the next music number, the system microcomputer 14 determines YES in step 242, stops the timer operation, and clears the current CF and PF. And P
N is 2 or more. The program number N (1) = 1 corresponding to the program number 1 is displayed on the NO display 26,
P. The PN = 1 is displayed on the NO display 28, and the program number 1 to PN is displayed on the music calendar display 22.
All program numbers up to -1 are displayed, and the total display time, which is the value of $ T, is displayed on the timer display 24 (steps 246 to 254).

Thereafter, the user sequentially proceeds to song numbers 3, 5, 7,
When 8, 11, and 15 are input, the system microcomputer 14
Is registered as a program tune of program numbers 2 to 7 of the program file. As a result, the registered contents of the program file are as shown in (1) of FIG. 9, and the display state is as shown in (1) of FIG. At this time, PN is 8.

Checking the program tune Here, when the user wants to check the programmed tune, he only has to turn on the CHECK key. For example, C
When the HECK key is turned on once, the system microcomputer 14
Determines YES in step 256 of FIG. 4, sets the CF, sets the check mode (at this time, turns on the fixed character display 29 of <CHECK> on the display unit 18), and sets the program check number PN '. Is incremented to 1 and after confirming that this PN 'has not reached PN, the total playing time of all the program tunes whose program numbers are from 1 to PN' is totaled as ΣT '(steps 258 to 264). ). Since PN 'is still 1 in this case,
T ′ = t (1).

The system microcomputer 14 is provided with the T.C. N
The O. display 26 displays the program number N (PN ') = 1 of the program tune corresponding to the program number PN'. The program check number PN '= 1 is displayed on the NO display 28, only N (PN') = 1 is displayed on the music calendar display 22, and the value of ΣT 'is displayed on the time display 24 (step 266). . Thus, the user knows that the registered music number of the program number 1 is 1 and that the playing time is known.

The system microcomputer 14 proceeds to step 266.
After the processing of (1) is completed, a timer is set to start time measurement (step 268). Therefore, if the user does not operate the keys until five seconds have elapsed since the timer started, the system microcomputer 14 proceeds to steps 240 and 2 in FIG.
After determining YES at 42, the timer is stopped and C
Since F is standing, CF is cleared to release the check mode (at this time, the fixed character display 29 of <CHECK> on the display unit 18 is turned off), and PN 'is also set to 0 (steps 246, 248, 270). Then, the display state is returned to the original state (steps 250 to 254).

On the other hand, if the user turns on the CHECK key once before 5 seconds have elapsed since the timer was set at step 268 in FIG. 4, the system microcomputer 14 keeps the flag CF set and sets PN '. Is incremented to 2 and the total playing time of two songs from program number 1 to PN ′ = 2 is set to ΣT ′ (steps 256 to
264). Then, the tune number N (PN ') = 3 of the program tune corresponding to the program number PN' is set to T. NO is displayed, and the program check number PN '= 2 is set to P.N. NO display, N
(PN ') = 3 is displayed in the music calendar, and @T
'Is displayed in time (step 266, see (2) in FIG. 10). Thus, the user knows that the registered tune number of program number 2 is 3, and also knows the total playing time of program numbers 1 and 2.

The system microcomputer 14 proceeds to step 266.
After the processing of (1) is completed, a timer is set to start time measurement (step 268). Hereinafter, similarly, the user can confirm the program tune having the program number 3 or later and the total playing time up to the tune only by repeatedly turning on the CHECK key by the user. If PN 'matches PN as a result of the processing in step 260 of FIG. 4, PN' is set to 1 (YE in step 262).
Judgment of S, 269). Therefore, after checking the registered music of the program number 7, by turning on the CHECK key again, the program number 1 can be checked again.

At the point where the program music is deleted during the STOP , for example, when the user wants to delete the registration of the music number 3 related to the program number 2, the user turns on the CHECK key twice successively and turns on the P.S. When the NO display becomes 2,
It is only necessary to turn on the CLEAR key once. If the CLEAR key is turned on while the CF is standing, the system microcomputer 14 determines YES in steps 272 and 274 in FIG. 6 and since the PF has dropped in this case (step 27).
No. 6), the playing time t (N (PN ')) for the music number N (PN') = 3 related to the program number PN 'from $ T
Is subtracted to obtain a new ΔT (step 277), the music number 5 corresponding to the program number of PN ′ + 1 = 3 in the program file is written in the program number PN ′ = 2, and the program number corresponds to PN ′ + 2 = 4. The music number 7 is written to the program number PN '+ 1, and each registered music whose program number is PN' + 1 or later is changed to a registered music whose program number is PN 'or later (step 278).
As a result, the music number 3 that originally existed as the music number related to the program number 2 has been deleted.

After the processing of step 278, the system microcomputer 14 obtains the total playing time of all the program tunes corresponding to the program numbers from 1 to PN 'and sets it as ΣT' (step 280), and the program tune corresponding to PN '= 2 Turn N (P
N ′) = 5. NO is displayed, and PN '= 2 is set to P.N. NO is displayed, N (PN ') = 5 is displayed in the music calendar, and the value of ΣT' is displayed in time (step 282, see (3) in FIG. 10). As a result, the user knows that the registered tune number 3 related to the program number 2 has been deleted and changed to 5, and also knows the total playing time up to the program number 2 after the deletion. The contents of the program file at this time are shown in (2) of FIG.

The system microcomputer 14 determines in step 282
After the processing of (2), the timer is set (step 284),
PN is decremented to 7 (step 286).
When the time counted by the timer exceeds 5 seconds, the system microcomputer 14 stops the timer and sets CF and PN 'in the same manner as described above.
(Steps 240 to 248, 27 in FIG. 8)
0), the track number N (1) = 1 related to the program number 1
NO is displayed, and 1 is set to P.N. No is displayed, the value of ΣT is displayed in time, the total playing time of all registered songs corresponding to the program numbers from 1 to 6 is displayed, and all program song numbers are displayed in the music calendar (steps 250 to 25).
4).

When it is desired to delete the last program tune in the program file in the state of (2) in FIG.
It is sufficient to simply turn on the CLEAR key once without turning on the HECK key. At this time, since the CF flag is not set, the system microcomputer 14 determines NO in step 274 of FIG. 6 and proceeds to step 288, and from ΔT, the program number N (PN-PN) whose program number corresponds to PN-1 = 6.
1) The performance time t (N (PN-1)) = t (15) is subtracted to obtain a new ΔT, and 2-digit hyphen data is written as a program music number corresponding to the program number of PN-1. 15 is cleared (step 289).

Then, the music number data corresponding to the program number PN-1 is stored in T. NO is displayed (at this time, <-> is displayed), and PN-1 = 6 is set to P.N. NO is displayed, and ΔT is displayed in time. In addition, as the music calendar display, the program music numbers corresponding to the program numbers 1 to PN-2 are displayed (step 290). As a result, the user knows that the program tune corresponding to the program number 6 has been deleted, and also knows the total playing time of all the program tunes after the deletion. The system microcomputer 14 determines in step 290
, The timer is set and PN is decremented (steps 284 and 286).

Addition of Program Music During STOP Conversely, when the contents of the program file are in the state of (2) in FIG. 9, the user wants to add music number 10 as a new program music at the position of program number 4, for example. In this case, it is sufficient to first turn on the CHECK key four times in succession, and then input the music number 10 using the numerical keys. When the CHECK key is continuously turned on four times, the system microcomputer 14 sets the flag CF and sets PN 'to 4 (repetition of steps 256 to 268). 4th CH
When the track number 10 is input with the numerical keys within 5 seconds after the ECK key is turned on, the system microcomputer 14 executes the processing shown in FIG.
Is determined to be YES in step 228, and the program number 1 at which the program number is PN-1 = 6
5 is written as a program tune with a program number PN = 7, and then a program number 11 with a program number PN-2 = 5
Is written as a program tune having a program number PN = 6, and a tune number 8 having a program number PN-3 = 4 (= PN ') is further written as a program tune having a program number PN = 5. Next, it is moved down (step 300 in FIG. 5).

Next, the input music number 10 is written and registered in the program music number 4 indicated by PN '(step 302).
As a result, the music number 10 is added in the middle of the program. The contents of the program file at this time are shown in (3) of FIG. Subsequently, the system microcomputer 14
T (N) = t (10) is added to T to obtain a new ΣT (step 303), and the total playing time of all the program tunes corresponding to the program numbers from 1 to PN ′ = 4 is added to ΣT ′. (Step 304), the input music number N = 10 is set to T. NO is displayed, and PN '= 4 is set to P.N. NO is displayed, N = 10 is displayed on the music calendar, and ΣT 'is displayed in time (step 306, see (4) in FIG. 10). This allows the user to know that the music number 10 has been inserted at the position of the program number 4.

Next, after the system microcomputer 14 confirms that the PF has been cleared (step 308),
The timer is set and the PN is incremented (steps 236 and 238 in FIG. 4). When the time counted by the timer exceeds 5 seconds, the timer is stopped and CF, PN '
(Steps 240, 242, 24 in FIG. 8)
6, 248, 270); NO display is N (1) = 1,
P. When the NO display is set to 1, all the program numbers related to the program numbers from 1 to PN-1 are displayed in the music calendar and ΔT is displayed in time (steps 250 to 250).
254). If the user inputs a track number again while the CF flag is still standing,
A new input music number is inserted as a registered music related to program number 4.

As described above, even after the program operation is completed, simply turning on the CHECK key a required number of times and designating a desired program number, and then turning on the CLEAR key or inputting a music number can be easily performed. With a simple operation, it is possible to delete a program tune at an arbitrary position in the program or to insert a new program tune.

Program Performance In the program state of (1) in FIG. 9 (PN = 8 at this time), when the user turns on the PLAY key, the system microcomputer 14 determines YES in step 310 of FIG. After confirming that the flag PF has been dropped and is in the STOP state, the flag PF is set to indicate that the performance is being performed (steps 312 and 314). Then, the system microcomputer 14 sets the program current performance number MN to 1 (step 316), and after confirming that the MN does not match the PN, performs a search control on the reproducing means 21 to make the program number MN. After the optical pickup 10 is adjusted to the head position of the registered music number N (MN) = 1, the PLAY control is performed to start playing the music of the music number 1 (steps 318, 320, and 32).
4, 326).

In this case, since the timer is not operating and the PF is standing, the system microcomputer 1
4 sets N (MN) = 1 to T.4. NO is displayed, and MN is set to P.N. NO
Display, time display of the P time (performance elapsed time) of the playing music based on the subcode input from the signal processing circuit 12, and music calendar display of the remaining program music numbers including the playing music ( N at step 240
O, 250, 328, see (5) in FIG. 10). Thereafter, the subcode input from the signal processing circuit 12 and the TO
When it is confirmed from the comparison of the C information that the music being played has ended, the system microcomputer 14 increments MN to 2 and proceeds to step 318 in FIG. 7 (determination of YES in step 330, 332).

When MN is 2, since PN = 8 still does not match, the system microcomputer 14 sets the program number to MN.
= 2 is searched for the start position of the program number 3 and the performance is started (steps 320, 324, 32)
6). Thereafter, in the same manner, the music of the music numbers 5, 7, 8, 11, and 15 is performed according to the program order. When the performance of the last program tune is completed Step 3 in FIG.
As a result of the process of 32, MN = 8. At this time, the system microcomputer 14 determines YES in step 318 of FIG. 7, performs STOP control on the reproducing means 21 (step 334), and clears the flag PF (step 33).
6). Also, when the user turns on the STOP key during the performance of the program, the
After confirming that F is set, STOP control is performed and the flag PF is cleared (steps 338 to 338 in FIG. 8).
344).

In contrast to this, when the program is being played in the program state of (1) in FIG. 9 (PN = 8 at this time), the user deletes the program number 3 from the program file. If you want to delete a song, you can easily delete it by the same operation as described above. For example, when the music number 7 related to the program number 4 is being played (the display state at this time is shown in (6) of FIG. 10), if the user turns on the CHECK key twice successively, the system microcomputer 14 sets the flag A CF is set, PN 'is set to 2, and the registered music number 3 related to the program number 2 is displayed (steps 256 to 268 in FIG. 4).
Repeat). And while CF stands, the user
When the LEAR key is turned on, the system microcomputer 14 determines YES in step 272 of FIG.
Since F and PF are standing, it is first determined whether PN 'matches MN (steps 274, 276, 34).
8).

In this case, there is no match, so that PN 'is
It is determined whether it is smaller than (Step 350). Here, since the result is YES, MN is decremented to 3 (step 352). Then, the process proceeds to step 277, in which t (3) is subtracted from ΔT in the same manner as described above, the program tunes after program number 3 are moved up one by one, and tune number 3 is deleted from the program file. The total performance time of the second and the second program music is assumed to be "T",
The music number and 'T' related to the program number 2 are displayed (steps 278 to 282, see (3) in FIG. 10). Subsequently, a timer is set, and PN is decremented to 7 (steps 284 and 286). The state of the program file at this time is as shown in (2) of FIG.

Thereafter, the display state does not change until the time counted by the timer exceeds 5 seconds, and after 5 seconds, the display returns to the display of the playing state under the control of the system microcomputer 14 (step 2 in FIG. 8).
40, 242, 246-250, 328). When the performance of the music number 7 is completed during the timer operation or after the stop, the system microcomputer 14 increments the MN and shifts to step 318 in FIG. 7 (NO in step 242 in FIG. 8, determination of 354, 330, 332, Or step 24
2 is YES, 246 to 250, 328, 330,
332). Since the MN has been previously decremented in step 352, it is 4 in this case. Therefore, the system microcomputer 14 can perform the next program music, that is, music number 8, following the music number 7 (steps 318 to 326 in FIG. 7). Even if the song at the program number position is deleted,
There is no chance of skipping one program tune by mistake.

In contrast to this, during the performance of the music number 7, the user turns on the CHECK key five times in succession in order to delete the music number 8, which is the fifth program music, and then CLEA.
When the R key is turned on, the system microcomputer 14
When the determination in step 350 is made, NO is determined because PN 'is 5 and MN is 4, and the MN decrement process in step 352 is not performed. When the music number 8 is deleted in the process of step 278, the music number 11 is moved up to the program number 5. On the other hand, when the performance of the music number 7 ends, the MN becomes 5 in step 332 of FIG. 8, and then the music of the music number 11 according to the program number 5 is performed (steps 318 to 326 in FIG. 7).

Therefore, even when a program tune after the tune being played is deleted, when the performance ends, the program tune corresponding to the program number next to the performance tune is played continuously. In this way, even after the PLAY starts, if a song that you do not want to dub to tape is registered by mistake, for example, if the song has not been played yet, dubbing to tape is not necessary before recording while continuing dubbing to tape. Program music can be easily deleted, and dubbing operation does not need to be interrupted.

When the user turns on the CHECK key three times and then turns on the CLEAR key during the performance of the music number 5 corresponding to the program number 3, the PN 'becomes 3 which is the same as the MN. The microcomputer 14 determines YES in step 348 of FIG. 6, and does not delete the program tune at this time. If the tune number being played can be deleted, the tune that is not included in the program file will be in a playing state, so to say, a malfunction state. Then, FIG.
When the display returns to the display indicating the playing state in the process of step 328, inconsistency occurs in the music calendar display and the like, and the user's recognition is confused.

Addition of Program Music During Program Performance Apart from this, it is also easy to add a new program music during the program performance.
For example, during the performance of the music number 7 in the program state of (1) in FIG. 9, after deleting the music number 3 related to the program number 2 as described above (the MN becomes 3 at this time), the program number 4 If you want to add track No. 10 to the CLEAR key and turn off CLEAR key and delete track No. 3 and 5 seconds have not yet passed, turn on the CHECK key twice consecutively.
Five seconds have elapsed since the LEAR key was turned on, and when the display returned to the playing state, the CHECK key was continuously turned on four times to set PN 'to 4, and before five seconds had passed since the last CHECK key was turned on. Track number 10 while CF flag is on
Enter

When a program number is input while the CF is standing, the system microcomputer 14 determines YES in step 228 of FIG. 4, and similarly to the above, the program programs 4 and thereafter are programmed one by one. The program is moved down (step 300 in FIG. 5), and the input music number 10 is written in the program number 4 (step 302, see (3) in FIG. 10). Then, t (10) is added to ΣT to obtain a new ΣT (step 303). The total playing time of the program tune from 1 to PN '= 4 is calculated to be ΣT', and the input tune number N = 10 is set. T. NO is displayed, and PN '= 4 is set to P.N. NO is displayed, and N = 10 of the music calendar is lit (step 306, see (4) in FIG. 10). And in this case PF
Is set, it is determined whether PN 'is equal to or less than MN (steps 308 and 356). In this case, PN '= 4,
Since MN = 3, NO is determined, and the MN increment processing in step 358 is not performed.

Then, a timer is set and PN is incremented (steps 236 and 238 in FIG. 4). After 5 seconds elapse after the timer is set, the display returns to the original performance display state (see (7) in FIG. 10). At this time, the music number 10 is additionally displayed on the music calendar (step 2 in FIG. 8).
40-248, 270, 250, 328). Thereafter, when the performance of the music number 7 is completed, and the determination at step 330 in FIG. 8 is YES, the system microcomputer 14 increments the MN to 4 and then plays the music of the program number 4 indicated by the MN. Therefore, the music number 10, which is the program music inserted earlier, is played (steps 318 to 326 in FIG. 7).

As a result, even after the start of the program performance, an unplayed program tune can be easily added to an arbitrary position and played. For example, even if the user has forgotten to program a tune to be dubbed on a tape, a tabbing operation can be performed. Can be added and a new song can be played while continuing, so that it is not necessary to stop the tape or the like.

If an insertion is made at a program number position equal to or earlier than the program number 3 of the music number 7 being played in the program state shown in (2) of FIG. The program tunes up to and including the program number 3 are shifted down to the program number 4 and thereafter (step 300 in FIG. 5), and the program number of the tune number 7 being played becomes 4; Is determined to be YES in step 356, and MN is incremented to 4 (step 358). Therefore, when the performance of the music number 7 is completed and MN is incremented in step 332 in FIG. 8, MN = 5, and then the music number 10 of the program number indicated by the MN is performed. It will not be played twice.

According to this embodiment, a new song can be added in the middle of a program by a simple operation of turning on the CHECK key a required number of times, specifying a desired program number, and then inputting a song number. It can be added not only when the CD player is in the STOP state, but also during the program playing, so that, for example, even after the dubbing to the tape is started, if the program number position before playing is still dubbing, Newly added songs can be dubbed together without stopping.

Also, by simply turning on the CHECK key a required number of times and designating a desired program number, and then turning on the CLEAR key, the program tune in the middle of the program can be deleted, and the CD player is in the STOP state. This is possible not only when you are playing a program, but also during program play.For example, even after you start dubbing to tape, if the program number position is still before playing, you can prevent dubbing of unnecessary songs without stopping dubbing it can.
Furthermore, during the performance of the program, the deletion of the music being played is prohibited, so that the contents of the performance display, the performance music, and the program contents are not inconsistent with each other, and a malfunction is prevented. There is no risk of confusion.

In the above-described embodiment, the insertion of a new program tune is performed when the program numbers are PN'-1 and PN '.
Although the program number is set between the program pieces, the program number may be set between the program pieces PN 'and PN'-1.

According to the program playing device of the disc reproducing apparatus of the present invention, when a program number is designated and a song number is input in a state where a desired music piece is programmed in the program storage means, In the program storage means, the program numbers of the program tunes after the designated program number (or one after the designated program number) are decreased by one, and the input tune number is designated by the designated program number (or designated program number). If the inserted program number is the same as or earlier than the current program number, the current program number is incremented. So, regardless of the STOP state and the program playing state, A new program song can be added in the middle of the program by a simple operation.Even if you add the same song to the current program number or the previous program number position during program play, the same song is repeatedly played by mistake. It will not be lost.

In the program playing apparatus of another disk reproducing apparatus according to the present invention, when a program number is designated and deletion is instructed in a state where a desired music to be played is programmed in the program storage means, the program is executed. In the storage means, the program numbers of the program tunes one after the designated program number are incremented one by one,
When a program song is deleted during playback, and when the deleted program number position is earlier than the program current performance number, the program current performance number is decremented. Program songs in the middle can be deleted by a simple operation, and even if a song at the program number position before the current program number is deleted during program play,
There is no chance of skipping one program tune by mistake.

In the program playing apparatus of still another disk reproducing apparatus according to the present invention, when an instruction to delete a program music is given at the time of reproduction, the program music deleting means sets the program number to be deleted to the program current performance number. At the same time, the deletion is not performed, so that inconsistency between the program playing operation and the program contents can be prevented, and a malfunction state can be prevented.
