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

FIG. 1 shows an in-vehicle compact disc reproducing apparatus according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an operation display unit including a power switch 2, a display unit 3, and a key input unit 4. The power switch 2 supplies and shuts off a battery voltage. The display section 3 displays the track number of the compact disc, the playing time, and the like. The key input unit 4 has functions such as a play key 4A, a stop key 4B, a mode switching key 4C, a track up key 4F, a track down key 4G, a repeat key 4I, and a cancel key 4J for controlling the operation of the reproducing unit 7. A key is provided. Reference numeral 5 denotes a power supply unit that converts the battery power supply voltage supplied via the power supply switch 2 into a voltage required for the operation display unit 1, the control unit 6, and the reproduction unit 7 and supplies the required voltage. 6
Is a central processing unit (CP) including a read-only memory (ROM).
U) A control unit including a 6A and a standby RAM 6B. The CPU 6A of the control unit 6 outputs an operation command to the reproduction unit 7 based on the key discrimination function for discriminating the key operated by the key input unit 4 and the key discrimination result. It has a playback operation control function, a playback 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 playback unit 7. The battery voltage is constantly supplied to the standby RAM 6B via the power supply unit 5, so that 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. When the track up key 4F or the track down key 4G is operated, the operation shifts to the operation of reproducing the next song after the currently reproduced song or the previous song before the currently reproduced song. These operations can be performed by a normal disk reproducing device.

Next, the reproduction cancel function of the 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, a 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, 1 is a step for determining whether playback is currently being performed, 2 is a step for executing processing required for playback, 3 is a step for determining whether the cancel key 4J is operated and turned on, and 4 and 5 are cancels. A step of determining whether or not a flag indicating that a timer started based on an ON operation of the key 4J is counting is set, 6 is a step of starting the timer, and 7 is a flag set in accordance with the start of the timer. Step 8 is a step of judging whether the timer has counted a predetermined time (for example, 2 seconds), 9 is a step of clearing canceled music data (track number or the like) stored in the RAM 6B, 10 is a step of resetting the flag, 11
Is a step of determining whether or not the canceled music data is stored in the RAM 6B, 12 is a step of determining whether or not the currently playing music is stored in the RAM 6B as canceled music data, 13 is a step of playing the next music, and 14 is A step of storing the currently reproduced song as a canceled song in the RAM 6B, a step of reproducing the next song, a step of resetting the flag, a step of determining whether the eject key has been operated, and a step of determining whether the eject key has been operated.
Is a step of clearing the canceled music data stored in the storage section, and 19 is a step of executing another processing for the ejection.

Next, the operation of this embodiment will be described with reference to FIG. When the play key 4A is operated by inserting the disk 8 into the playback unit 7, the playback operation is started, and playback is sequentially performed from the first music. Now, it is assumed that the reproduction of the first and second music pieces has ended and the reproduction of the third music piece is in progress. In this case, it is determined in step 1 in FIG. 2 that the reproduction is currently being performed, various processes for reproduction are performed in step 2, and it is determined in step 3 whether the cancel key 4J is on. Since the cancel key 4J has not been turned on, the process proceeds from step 3 to step 5, and it is determined whether or not a flag set at the time of starting the timer is set. However, since the flag is not set, the process proceeds to step 16 to reset the flag. And the process proceeds to step 11.
In step 11, it is determined whether the canceled music data is stored in the RAM 6B. If the determination is no, 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 track is in progress, the determination in step 3 is YES, and
At step 4, it is determined whether the flag is set.
Since the flag has not been set so far, step 4
Then, the determination is no, and the process proceeds to step 6 to start the timer. Then, the flag is set in step 7 and the process proceeds to step 8. In step 8, it is determined whether or not the activated timer has timed out for a certain time. However, since the time has not been measured for a certain time, it is determined as NO, and the process proceeds to step 11, where it is determined whether or not the canceled music data is stored in the memory. Step 1
If it is determined in step 1 that the canceled music data is not stored, the process returns to step 1 and proceeds to step 1 → step 2 → step 3 → step 4. In step 4, it is determined whether the flag is set. Since the flag is set in step 6, it is determined as YES in step 4, and it is determined in step 8 whether the timer time has been measured for a certain period of time. Return to step 1. Thereafter, 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 a 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 canceled song data. Next, in step 15, the reproduction of the third music currently being reproduced is stopped, the reproduction of the fourth music is started, the flag is reset in step 16, and the process proceeds to step 11. In step 11, R
It is determined whether the canceled music data is stored in AM6B. At this stage, since the third tune has been 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 the currently reproduced (fourth tune) is stored as the canceled tune. However, since the fourth tune is not stored as the canceled tune, the determination is no and the process returns to step 1.

After the third song is registered as a canceled song as described above, the fourth song is played, the fifth song is played, and so on.
······················································································· 1
The playback of the second song progresses and 3 registered as a canceled song
When the reproduction of the music is started, the process proceeds to step 1 → step 2 → step 3 → step 5 → step 16 → step 11, and in step 11, it is determined that the answer is yes.
Proceed to step 2 and play back in step 12 (during playback of the third song)
It is determined whether or not the song is registered as a canceled song in the RAM 6B, and the result is determined to be YES. Then, the process proceeds to step 13 and immediately after the reproduction of the third song is started, the reproducing process of the fourth song is started.

As described above, if the cancel key is operated for a shorter time than the predetermined time (2 seconds) while the music recorded on the disk 8 is being reproduced in the predetermined order, the music reproduced at the time of operating the cancel key is operated. Is stopped in the middle of the process, and the reproduction operation of the next music is started, and the reproduction of the next music is registered in the RAM 6B as a canceled music, and the reproduction of the third music is skipped immediately after the start of the reproduction of the next third music.

Next, referring to FIG. 2, an operation when the cancel key 4J is operated for a time longer than a 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. If the cancel key operation is continued for 2 seconds, the determination is YES in step 8 and the RAM 6B in which the canceled music is registered is cleared in step 9 and the flag is reset in step 10. When the eject key is operated during the reproduction, steps 1 to 17 are performed.
And the answer is yes in step 17 and step 18
The memory for canceling song registration (RAM 6B) is cleared in step 19, and the ejection process is performed in step 19
It is to return to.

In the above-described embodiment, a tune that the user does not want to listen to during the playback operation is registered, and the playback operation of the tune registered at 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, during the reproducing operation of sequentially reproducing all the songs recorded on the disc from the first song, a song that the user does not want to listen to is registered, and the reproduction of the registered song is skipped thereafter. It is also possible to register a canceled song by operating the cancel key during program playback for registering and playing a song to be listened, and to skip playback of the registered canceled song thereafter.

Although the present invention is an example of a reproducing apparatus for reproducing one disk, the present invention may be applied to a disk changer apparatus for selecting and reproducing a plurality of disks.

[0021]

As described above, according to the first aspect of the present invention, when there are few songs that the user does not want to listen to among a plurality of songs recorded on the disk, the operation of registering the songs that he does not want to listen to is reduced. In other words, program reproduction becomes easy.

According to the second aspect of the present invention, the first aspect
In the same way as in the invention of the above, it is easy to register a song that the user does not want to listen to, and since the song that is being played can be registered as a canceled song while listening to the song being played, the track number of the song that the user does not want to hear can be identified. You can register songs you do not want to listen to even if you do not have them. Further, since it is determined whether registration of a canceled song is required by actually listening to a song, there is an advantage that a desired song is not erroneously registered as a canceled song.

According to the third aspect of the present invention, in addition to the effects of the first and second aspects of the present invention, the execution of the cancel music memory function and the cancellation of the cancel music memory function can be performed by operating one key. It has the advantage that it can be released.
