[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recording / reproducing apparatus, and further has so-called CD dubbing and tape dubbing functions for recording music information recorded on a disc-shaped recording medium or a tape-shaped recording medium onto another tape-shaped recording medium. The present invention relates to a recording / reproducing device.

[0002]

[Prior Art]

 Conventionally, as this type of recording / reproducing apparatus, there is one as described in JP-A-63-48681 (G11B 27/02). In this conventional technique, if the recording medium of the recording device reaches the end while the disc reproducing device is reproducing the disc information, after the disc reproducing device cues the music being reproduced at that time, After the recording medium is reversed, the disc playback device is released from the paused state, and recording is restarted from the beginning of the song that was interrupted at the end of the recording medium, so that the information on the recording medium is not lost. It should be recorded in.

In this conventional technique, information on the disc can be recorded without being lost, but at the end of one side of the recording medium, there is a drawback that the recording which is interrupted in the middle of the song remains. is there. Therefore, in recent years, when the end of the recording medium is detected, the disc playback device detects the beginning of the song in the middle of recording and pauses, and the recording device rewinds while detecting the interval between the songs of the recording medium, and then , After erasing the last song that was recorded only halfway, flip the recording medium, cancel the pause state of the disc playback device, and start recording again from the beginning of the song that was interrupted at the end of the recording medium. The recording / reproducing apparatus according to the above has been proposed.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional technology, in order to erase the last song that was recorded only halfway, playback is performed while rewinding at high speed, and the last song to be erased is detected by detecting the change in the recording level. It is typically configured to search the head of. However, since the recording medium is rewound at high speed, it is difficult to accurately find the beginning of the song, and if the level of the beginning of the song to be erased is small or the interval between songs is short, the beginning of the song to be erased In some cases, the previous song may be rewound without stopping, and as a result, even the correctly recorded song may be erased.

[0005]

[Means for Solving the Problems]

 In order to improve the above-mentioned conventional technique, the present invention provides a recording / reproducing apparatus including a reproducing apparatus for reproducing a recording medium on which a plurality of songs are recorded, and a tape recorder for recording the songs reproduced by the reproducing apparatus. A music interval detecting means for detecting a music interval during the reproducing operation of the reproducing device, a counter for counting a count value according to the tape running amount of the tape recorder, and an end detection for detecting the end of the tape recorder. Means for resetting the counter when a music interval is detected by the music interval detecting means, and setting the tape recorder to a rewind mode until the counter becomes 0 when the end is detected by the end detecting means. It is characterized by having a control circuit.

[0006]

[Action]

 When dubbing the music played by the playback device by the tape recorder, the dubbing is performed while resetting the counter for each music, and when the tape end is detected by the end detecting means, the value of the counter becomes 0. Until the beginning of the song that could not be completely recorded.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the structure of a recording / reproducing apparatus according to the present invention. In the figure, 1 is a CD player as a reproducing apparatus, and a plurality of songs recorded on a disc 2 are reproduced by a pickup 3. .. Reference numeral 4 is a mode setting circuit for setting the operation mode of the CD player 1, and reference numeral 5 is a search for searching a plurality of songs recorded on the disc 2 for a song desired by the operator or a song designated by the control circuit 6. The circuit 7 is a detection circuit for detecting the interval between the songs reproduced from the disc 2.

Music information reproduced from the CD player 1 is recorded on the tape in the cassette 11 by the magnetic head 10 of the tape recorder 9 via the dubbing circuit 8. Reference numeral 12 is a mode setting circuit for setting the operation mode of the tape recorder 9, 13 is an end detecting circuit for detecting the end of the tape, and 14 is an inversion control circuit for reversing the running direction of the tape recorder 9 by detecting the end of the tape by the end detecting circuit 13. is there. Reference numeral 16 is a rotation detection circuit for detecting the rotation of the capstan 15, and the detection signal causes the counter 17 to count up or count down according to the tape running.

Next, the operation of the recording / reproducing apparatus according to the present invention will be described with reference to the flowchart of FIG. First, when the dubbing start is instructed in step 18, the control circuit 6 resets the counter 17 (step 19), sends a control signal to the mode setting circuits 4 and 12 and the dubbing circuit 8, and causes the tape recorder 9 to operate. The recording mode and the reproduction mode of the CD player 1 are set respectively, and dubbing is started (steps 20, 21, and 22).

When it is detected by the inter-track detection circuit 7 that the inter-track of the music information is detected during the dubbing mode, the control circuit 6 resets the counter 17 to set the count value to 0 (step 24). Further, during reproduction other than between songs, the rotation detecting circuit 16 counts up the counter 17 according to the rotation of the capstan 15, that is, in accordance with the running amount of the tape (step 25), and at step 26, the terminal ends. These processes are repeated until the detection circuit 13 detects that the tape end has been reached. When it is detected in step 26 that the tape end has been reached, it is determined in step 27 whether the CD player 1 is reproducing the music in the middle of the music or in the music interval. If it is in the middle of a song, the mode setting circuit 4 and the search circuit search the head position of the song in step 28, and set the CD player 1 in the pause state in step 29.

On the other hand, the tape recorder 9 is set to the rewind mode by the mode setting circuit 12 in step 30. At this time, in step 31, the counter 17 is counted down in accordance with the rewinding amount of the tape, and in step 32, the count value of the counter 17 becomes 0, that is, until the beginning of the last piece of music recorded intermittently. It is rewound. The rewinding amount is accurately detected by the counter 17, and it is surely rewound to the beginning of the music. Then, in step 33, the mode setting circuit 12 sets the erasing mode, and the tune recorded intermittently during the erasing is erased. This erasing is performed until the tape end is reached by the detection of the end detection circuit 13.

When the erasing is completed, it is judged in step 34 whether the surface is the A surface or the B surface. If the surface is the A surface, the reversing circuit 14 reverses the traveling direction in the step 35, and the recording of the B surface is continued. The processing from step 19 is repeated in order to perform. If it is determined in step 34 that it is not the A side, that is, the B side, the dubbing is ended.

When it is determined in step 27 that the tape end is reached not between the songs but between the songs, the process jumps to step 34 without performing the processes of steps 28 to 33.

By the above operation, the piece of music recorded intermittently on the way is surely erased and dubbing is performed.

Although the present embodiment is configured to erase a song that was interrupted and recorded during recording, if the value of the counter 17 at the time of reaching the tape end is stored, the recording is interrupted during recording. It is possible to perform reliable fade-out recording by re-recording the recorded song and gradually lowering the recording level below the predetermined stored count value.

[0016]

As described above, according to the recording / reproducing apparatus of the present invention, it is possible to accurately rewind to the beginning of a piece of music recorded intermittently during tape dubbing, and perform correct dubbing.
