Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a tape recorder with a disc player having an auto-reverse function. 2. Description of the Related Art In addition to analog LP records which have been used and loved for many years, DADs (digital audio discs) which convert music signals into digital signals and record them have recently been used. CD ")
However, it is becoming widespread despite its short development history. The reason is that it is excellent in various sound quality characteristics such as a frequency characteristic and a dynamic range and is formed compactly. That is, the LP record has a diameter of 30
The CD is only about 12cm, whereas the CD is only about 12cm, and it is recorded at a high density on each stage. is there. Due to the difference in size between both types of recording disks, LP record players have never been mounted on portable recording / reproducing machines (hereinafter referred to as "tape recorders"). The CD player is rapidly progressing in miniaturization and has already been made portable, and has also been mounted on a portable (of course, a stationary type) tape recorder.
On the other hand, a tape recorder using a cassette tape is also enhanced in function, and when recording or reproducing, the magnetic tape (hereinafter, also simply referred to as "tape") is completed and the tape runs immediately when the tape comes to an end. A device having a so-called auto-reverse function for automatically reversing and reversing the magnetic head for recording and recording (or having a head chip for four channels in advance) and continuing the recording or reproducing operation has already been developed. , Is spreading. Also,
The cassette type magnetic tape used for this purpose has also been improved in various characteristics, and several types of tapes are available on the market, ranging from a short recording time of about 30 minutes for reciprocation to a maximum of 2 hours. However, since the two-hour tape has some weaknesses in mechanical characteristics such as tension, a 90-minute or 60-minute reciprocating tape is often used for sound quality-oriented recording. Therefore,
When recording (dubbing) all songs recorded on a CD onto a cassette tape using a tape recorder with a CD player with auto-reverse function (hereinafter, also simply referred to as "CD TV"), the total recording time of all songs It is reasonable to use 60-minute tape for about 55 minutes (including blank time between songs) for about 55 minutes (including about 50-70 minutes), and 90-minute tape for more than 85 minutes . [0005] As is well known,
A leader tape (non-magnetic material) of several tens of centimeters is connected to both ends of the cassette tape, and the magnetic tape is attached to the reel hub via this. The auto-reverse function operates not by detecting that the magnetic tape has been replaced by the leader tape, but by detecting that the tape has stopped running. Therefore, add a magnetic head to the leader tape.
Since no sound is recorded while the card is in contact, the music is cut off for 6 to 8 seconds before and after the auto reverse operation. Therefore, even if the no-signal portion between the songs rushes to the leader tape, the no-signal portion is at most about 7 seconds, so it is almost impossible to avoid the break of the song. Since the tape running and the reversal of the magnetic head are performed automatically, there is the convenience that the user does not need to be on the side during recording, but there is a missing part in the recorded music. It is unpleasant that it occurs. Even if the recorded song is an unknown song, it may be unclear whether the silent part that occurs during playback or appreciation is a broken part or a blank part between two songs. Has the disadvantage that the user must monitor the tape at least when it is near the end of the outward path. Accordingly, the present invention provides the following configuration in order to solve the above-mentioned problems. According to the present invention, there is provided a disk reproducing section (11) for reproducing information signals such as music and TOC information recorded on a disk (8) via a pickup (9), and a tape running in a recording state. the tape traveling mechanism having a function capable of inverting (16), in the tape recorder with a disc player having a means for performing the dubbing from the disc (8) to the tape (6) from said disk (8) an operation key for instructing the dubbing operation to the tape (6), the tape end detecting unit for detecting a tape end by the travel stop of the upper Symbol tape (6) and (18), the reproduction of

An embodiment of a tape recorder with a disk player (CD telephone) according to the present invention will be described with reference to FIG. FIG. 1 shows a CD telephone 10 of the present invention.
3 is a block diagram of a main part configuration of FIG. In FIG. 1, reference numeral 11 denotes a CD reproducing unit which includes a pickup 9, a reproducing mechanism (CD mechanism) 12 and a signal reproducing unit 13, and reproduces a music signal and TOC information from a CD 8. The digital signal read by the pickup 9 is subjected to error detection, correction,
A / A conversion and other signal processing are performed, and the next stage of the recording amplifier 14
After being amplified to an appropriate level and biased by an AC signal from the transmitter 15, it is electromagnetically converted by the recording / reproducing magnetic head 7 and recorded on the tape 6. 19
Is an operation key for instructing a dubbing operation, and 18 is a
This is a tape end detection unit that detects a tape end (leader tape) , and forcibly stops a tape traveling mechanism unit (hereinafter, also referred to as a “tape mechanism unit”) 16 (reel rotating shaft or the like) when the tape 6 stops running. When it is received, it detects it and outputs a signal to the control circuit 17. The control circuit 17 includes a storage unit for storing the TOC information reproduced from the disk, the number of music pieces (bands) being recorded based on the TOC information, and the elapsed time from the beginning of the music piece (band) being recorded. And a silence state between songs at the end of the tape as described later.
And a silent state detecting section for detecting . And
When the tape end is detected by the detection signal from the tape end detecting section 18 , the control circuit 17 controls the data from the arithmetic section and the music interval detected by the silent state detecting section.
Based on the silence of the tape, etc.
When the music is missing, the pickup 9 is returned to the beginning of the missing music, the tape running mechanism 16 is operated to reverse the tape 6, and after a lapse of a predetermined time (about 4 seconds) , the music is lost. While dubbing resumes from the beginning of the song,
If not missing, pick up 9 at the beginning of the next song
And the tape traveling mechanism 16 is operated to operate the tape.
After a predetermined time (about 4 seconds) has passed after reversing
Dubbing is resumed from the beginning of the next song. Next, an operation method for dubbing all songs recorded on a CD to a tape using the CD tele-recorder 10 of the present invention will be described with reference to the flowchart of FIG. A power switch provided on an operation panel (not shown) of the CD telephone 10 is closed, and the CD
The tape 8 is mounted on the turntable 5 and a new (or recorded) tape is mounted on a tape mounting unit (not shown) of the tape mechanism 16. Then, the control circuit 17 immediately detects that the CD is loaded (step S1 in FIG. 2), and reads the TOC information (information such as the number of tracks and the recording time) recorded at a predetermined location on the CD. It is stored (step S2 in the figure).
Next, when the user presses the operation key 19 to instruct a dubbing operation, the control circuit 17 detects this (step S3 in the figure) and outputs a signal to the tape mechanism 16 to set it to a recording mode ( Step S4 in the figure, the playback mechanism 1
2 to start the reproduction of the CD (step S5 in the figure). In this case, control is performed such that the music information recorded on the CD 8 is reproduced after the time (around 4 seconds) until the leader tape portion connected to the beginning of the tape 6 has passed through the head 7 has elapsed. The circuit 17 is configured. The recording on the tape 6 proceeds (step S6 in FIG. 2), and when the outward path is finally completed and reaches the end of the tape, the reel 4 stops rotating and the detection signal from the tape end detecting unit 18 is controlled. The signal is output to the circuit 17 (step S7 in FIG. 7), and the control circuit 17 receiving this signal temporarily stops the CD playback operation of the playback mechanism 12 (by moving the pickup 9 away from the CD 8) and the recording operation of the tape mechanism 16 The operation is stopped (steps S8 and S9 in the figure). Subsequently, the tape is immediately reversed (step S11 in FIG. 2), and the magnetic head is also reversed.
Based on the TOC information, the number of the music piece whose recording was interrupted (the number of the music piece) and the elapsed time from the beginning of the music piece to the stop of the tape are calculated, and the pickup 9 is moved to the beginning of the interrupted music piece. The tape mechanism 1 restarts the playback operation, and at the latest, at the time of the restart, starts the reverse rotation of the tape.
6 (including the recording circuit section) is returned to the recording mode, recording is started on the track on the backward path of the tape, and the dubbing operation is continued (step S13 in FIG. 11). The above C
The point at which the D playback operation is resumed is 4 to
Set after 5 seconds (to avoid leader tape). When the end of the tape is detected, there is no gap between the music pieces.
It can be in the sound state (blank part ) or at the beginning of the next song. In such a case, the last part of the song that has just been recorded reaches the leader tape. Since it can be missing,
The control circuit 17 must judge as accurately as possible whether or not the music piece is missing, and take measures. In other words, if a piece is missing, the pickup 9 must be moved to the beginning of the song and re-recorded on the return path of the tape. If not missing, the pickup 9 must be moved to the beginning of the next song and likewise moved. This is because recording is restarted (step S12 in FIG. 2).
Therefore, as an example of a countermeasure in such a case, for example, the following configuration is adopted. Although the length of the leader tape varies slightly depending on the tape, the elapsed time for one way is approximately three to four.
Since it is within seconds, this is defined as t ₂ = 4 (seconds). next,
The timer built in the control circuit 17 is started when the music ends (the tone signal level becomes almost zero). In this case, since the silence time between music pieces may be less than 4 seconds, counting of the silence elapsed time is not stopped even when the next music piece starts. Then, the time t _{1 at} which the detection signal from the tape end detecting section 18 is supplied (ie, the elapsed time from the end of the music until the tape 6 stops) is compared with the above-mentioned t ₂ (step S10 in FIG. 2). If t ₁ <t _{2, the} pickup 9 is returned to the beginning of the song whose reproduction has just ended (step S14 in the figure) and the dubbing operation is restarted (step S13 in the figure). If t ₁ > t _2, the reproduction operation of the CD 8 is stopped immediately, and after the time t ₂ has elapsed after the reversal of the tape, the next music (band) is reproduced (step S 1 in FIG. 4).
2). When the end of the tape is detected because the silent time between songs is too short, playback of the beginning of the next song may be started. It is desirable to configure the control circuit 17 so that the dubbing operation is restarted after the pickup 9 is returned (step S13 in the figure). Furthermore, when there is not enough room for the length of the tape used for recording, the end of the last piece of music may be missing. As an example of a method of coping with such a case, for example, the following configuration is adopted. First, the operation key 19
Is input to the control circuit 17 in addition to the instruction of the dubbing operation, as well as the type of tape to be used (recording time 46 minutes, 60 minutes, 90 minutes, etc.). Next, the total music recording time of the CD obtained by the TOC information is subtracted from the tape recording time. The value is referred to as "time to spare" or the like.
It is more convenient to display on a display unit (not shown) of the main body or to generate a warning sound when there is a shortage. Next, the elapsed time from the start of each song (band) is counted by the timer of the control circuit 17, and from the beginning of the song whose recording is interrupted by the leader tape portion at the end of the tape to the stop of the tape. the elapsed time t ₃ of the comparison with the margin time t _4. Then, if t ₃ <t _4, after the tape running reversal (elapse of + t ₂ ), dubbing is resumed from the beginning of the song interrupted as described above, and if t ₃ > t ₄ , the dubbing is continued, or about 5 to 6 seconds The dubbing is continued after the pickup 9 is returned. Instead of the above configuration, the tape end detecting section 18 detects this just before the leader tape portion of the tape end reaches the magnetic head 7, and controls the tape mechanism section 16 by inputting this detection signal. The control circuit 17 may be configured to send a signal to reverse the running of the tape 6 (and the magnetic head 7). Further, in the above description, the tape end detecting section 18 is provided, and the tape end is detected by the tape end detecting section 18, and then the tape is reversed to run the dubbing from the beginning of the interrupted music. It is to be restarted. As a result, the last recorded song on the outbound route is almost always
It will be cut off on the way. Therefore, the tape end detecting unit 18
Instead of using, a tape remaining amount detecting means is provided, for example, the remaining time of the tape is detected each time recording of one song is completed,
The remaining time is compared with the playing time of the next song obtained from the TOC information, and if it is determined that the remaining time has become shorter, dubbing is interrupted, fast-forwarding to the end of the tape, tape running (and tape running). If the dubbing is resumed after the (magnetic head) reversal, the interruption of the recording is logically eliminated. However, such a configuration is the same as the tape end detection unit 1
8, the calculated remaining time is generally inaccurate due to differences in the reel hub diameter of the cassette used, variations in the thickness of the tape, and variations in tightness. It is. As a result, the end of the recorded song is missing (in that case, the missing part is not recorded at the beginning of the return trip), but despite the tape remaining enough, "playing time of the next song">"remainingtime" It may be erroneously determined. Even if it is correctly determined, when the tape is reproduced and viewed, there is a very high possibility that a silence period of several minutes or more will occur when switching from the forward path to the return path. In that regard, when dubbing is performed by the tape recorder with a disk player according to the present invention, such a silent period occurs at most about 10 seconds, so that the tape is not wasted and continuous without waiting for a long time on the way. In this respect, the present invention is also excellent. As described above, according to the first aspect of the present invention, the recording is interrupted by the leader tape portion at the end of the tape using the TOC information recorded in advance on the CD. The saved song can be saved and dubbing without missing parts can be realized. That is, the tape end is detected by the tape end detecting section.
When issued, the control circuit checks if the song is missing at the end of the tape
Judging, if the song is missing, the above pickup is missing
Return to the beginning of the song and operate the tape
After a predetermined time has elapsed after the tape
Since dubbing is resumed from the beginning of the song,
It is possible to completely recover the missing parts such as the broken end. one
On the other hand, if the song is not missing,
Move to the beginning of the song and operate the tape running mechanism
After the tape has been reversed and the predetermined time has elapsed,
Since dubbing is restarted from the beginning of the song,
But you can continue to record and play back the next song
