U) It is a control unit composed of 6A and a standby RAM 6B, and the CPU 6A of this control unit 6 outputs the operation command to the reproduction unit 7 based on the discrimination function for discriminating the key operated by the key input unit 4. It has a reproduction operation control function, a reproduction skip function for skipping a canceled song stored by a cancel key operation, a display control function for displaying a track number, a playing time and the like on the display unit 3 according to the state of the reproduction unit 7. The battery voltage is constantly supplied to the standby RAM 6B through the power supply unit 5, and the stored contents can be retained even when the power switch 2 is turned off.

In FIG. 1, when the disc 8 is inserted into the reproducing section 7 and the play key 4A is operated, the reproducing operation of the disc 8 is started, and when the stop key 4B is operated, the reproducing operation is ended. Further, when the track up key 4F or the track down key 4G is operated, a transition is made to the reproduction operation of the music next to the music currently being reproduced or the music before the music being currently reproduced. These operations can be performed by an ordinary disc reproducing device.

Next, the reproduction canceling function of this embodiment will be described with reference to FIG. When the power switch 2 is turned on and the play key 4A is turned on, the processing shown in FIG. 2 is started, the disc reproducing operation is started, and a plurality of songs recorded on the disc 8 are sequentially reproduced from the first song. In FIG. 2, reference numeral 1 is a step for determining whether the reproduction is currently being performed, 2 is a step for executing a process required for reproduction, 3 is a step for determining whether or not a cancel key 4J is operated and turned on, 4, 5 are cancels. A step of determining whether or not a flag indicating that the timer activated based on the ON operation of the key 4J is being timed is set, 6 is a step of activating the timer, and 7 is a flag set in association with the activation of the timer. Step 8 is a step of determining whether or not the timer has counted a certain time (for example, 2 seconds), 9 is a step of clearing canceled song data (track number etc.) stored in the RAM 6B, 10 is a step of resetting the flag, 11
Is a step of determining whether the canceled song data is stored in the RAM 6B, 12 is a step of determining whether the currently playing song is stored as the canceled song data in the RAM 6B, 13 is a step of playing the next song, and 14 is a A step of storing the music being reproduced as a canceled music in the RAM 6B, a step 15 of reproducing the next music, a step 16 of resetting the above flag, a step 17 of judging whether the eject key is operated, and a RAM 6B of 18
Step 19 is a step of clearing the canceled music piece data stored in step 19, and step 19 is a step of executing another process for ejecting.

Next, the operation of this embodiment will be described with reference to FIG. When the disc 8 is inserted into the reproducing section 7 and the play key 4A is operated, the reproducing operation is started and the reproduction is sequentially performed from the first music piece. Now, it is assumed that the reproduction of the first and second songs has ended and the reproduction of the third song is in progress. In this case, it is determined in step 1 of FIG. 2 that the reproduction is currently being performed, various processing for reproduction is performed in step 2, and it is determined in step 3 whether the cancel key 4J is on. Since the cancel key 4J is not turned on, the routine proceeds from step 3 to step 5 and it is judged whether the flag set at the time of starting the timer is set. However, since the flag is not set, the routine proceeds to step 16 and the flag reset processing is performed. Then, the process proceeds to step 11.
In step 11, it is determined whether or not the canceled music piece data is stored in the RAM 6B. If NO is determined here, the process returns to step 1 and the same steps are repeated thereafter. If the cancel key 4J is operated while the reproduction of the third song is in progress, it is determined as YES in step 3,
In step 4, it is determined whether the flag is set.
Since the flag has not been set so far, step 4
Then, it is determined to be no, the process proceeds to step 6 to start the timer, then the flag is set at step 7 and the process proceeds to step 8. In step 8, it is determined whether or not the activated timer has timed for a certain period of time, but since it has not yet timed for a certain period of time, it is determined to be no, and the process proceeds to step 11 to determine whether the canceled music piece data is stored in the memory. Step 1
If it is determined that the canceled song data is not stored in step 1, the process returns to step 1, and proceeds to step 1 → step 2 → step 3 → step 4, and it is determined whether the flag is set in step 4, but it is already step Since the flag is set in step 6, it is determined to be yes in step 4, and then it is determined in step 8 whether or not the time measured by the timer has been measured for a certain period of time. Return to step 1. After that, when the cancel key 4J is continuously operated, the above steps are repeated. However, if the cancel key 4J is turned off before the timer measures the predetermined time (for example, 2 seconds), it is determined as no in step 3 and the process proceeds to step 5. In step 5, it is determined whether the flag is set. Since the flag has been set in step 7 as described above, the determination in step 5 is YES, and in step 14, the track number of the song currently being reproduced is stored in the RAM 6B as cancel song data. Next, in step 15, the reproduction of the third music piece that is currently being reproduced is stopped, the reproduction of the fourth music piece is started, the flag is reset in step 16, and the process proceeds to step 11. R in step 11
It is determined whether the canceled music piece data is stored in the AM 6B. At this stage, since the third piece of music is stored in step 14, the determination in step 11 is YES, and the process proceeds to step 12. In step 12, it is determined whether or not the song currently being played (the fourth song) is stored as a canceled song, but since the fourth song is not stored as a canceled song, it is determined as no and the process returns to step 1.

After registering the third song as a canceled song as described above, the fourth song is played, the fifth song is played ...
.... When the last song is played, the first song is played,
Proceed with the reproduction of the 2nd song, and it was registered as a canceled song 3
When the reproduction of the song starts, the process proceeds in the order of step 1 → step 2 → step 3 → step 5 → step 16 → step 11. In step 11, it is determined as YES, and step 1
Go to 2 and play in step 12 (playing the third song)
It is determined whether or not the song is registered as a cancel song in the RAM 6B, and as a result of the determination, the process proceeds to step 13, and immediately after the reproduction of the third song is started, the operation of reproducing the fourth song is started.

As described above, when the cancel key is operated for a time shorter than the predetermined time (2 seconds) while the songs recorded on the disk 8 are being reproduced in the predetermined order, the song reproduced when the cancel key is operated. The reproduction of No. 3 is stopped in the middle and the operation of reproducing the next music is started. At the same time, the reproduction of the third music is skipped immediately after the reproduction of the next third music is started.

Next, referring to FIG. 2, the operation when the cancel key 4J is operated for a time longer than the predetermined time (2 seconds) will be described. When the cancel key is operated, the timer is started and the flag is set as described above. When the cancel key operation is continued for 2 seconds, the RAM 6B in which YES is determined in step 8 and the cancel music is registered is cleared in step 9, and the flag is reset in step 10. Also, if the eject key is operated during playback, steps 1 to 17
Go to step 18 and determine yes in step 17
The canceled song registration memory (RAM 6B) is cleared in step 19, the eject process is performed in step 19, and step 1
Return to.

In the above-described embodiment, a song that the player does not want to hear is registered during the playback operation, and the playback operation of the song that is registered during the next playback is skipped. It is also possible to skip the reproduction of the registered music at the time of reproduction. Further, the above embodiment is an example in which all the songs recorded on the disc are sequentially reproduced from the first song, and the songs which are not desired to be heard are registered in the reproducing operation, and the reproduction of the registered songs is skipped thereafter. It is also possible to register the canceled music by the above-mentioned cancel key operation during the program reproduction for registering and reproducing the music to be listened to and skipping the reproduction of the registered canceled music.

Further, although the present invention is an example of a reproducing apparatus for reproducing one disc, the present invention may be adopted for a disc changer device for selecting and reproducing a plurality of discs.

[0021]

As described above, according to the first aspect of the present invention, when there are few songs which one does not want to hear among a plurality of songs recorded on the disc, the number of registration operations of the songs which one does not want to hear is reduced. This makes it easy to reproduce the program.

According to the second aspect of the present invention, the first aspect
Like the invention of the above, it is easy to register songs that you do not want to hear, and because you can register the songs that you are currently playing as a cancel song while listening to the song that you are actually playing, you can know the song number of the song that you do not want to hear. You can register songs that you don't want to hear even if you don't have them. Further, since the user actually listens to the music to determine whether or not to register the canceled music, there is an advantage that the music desired to be listened to is not mistakenly registered as the canceled music.

According to the third invention of the present invention, in addition to the effects of the first and second inventions, the cancellation music memory function is executed and the cancellation music memory function is executed by operating one key. It has an advantage that it can be released.
