The replaced song title information signal stored in 4b is supplied to the parallel/serial conversion circuit 41 via the video RAM 28 and character encoder 40, where it is converted into a serial signal, and then converted into an FM signal by the FM modulation circuit 45. The songs are recorded at the beginning of the tape of the cassette tape recorder 2 in the order of the selected songs.

Note that when recording the song title, an end signal is recorded at the end of the song title information by picking up a specific symbol with the light pen 4.

Track search for open tape recorder Here, the video RAM 28 is configured to scan and read out the stored information, and output a scanning end signal when it reaches the final scanning position.
At the point when the scanning of the song title during the song name recording is completed, an end signal is supplied to the recording pause drive circuit 51 to temporarily pause the cassette tape recorder 2, and is also supplied to the determination (comparison) circuit 46 to drive the open tape recorder. 1 to the playback state and run the open tape.

The counter value of the memory byte corresponding to the first selected song that has been re-stored in the counter storage unit 38 and the instruction of the counter (hereinafter referred to as a linear counter) connected to the rotation speed detection device of the open tape recorder 1. is compared with the counter value in the judgment (comparison) circuit 46, and this comparison output signal is sent to the play/fast forward 7 rewind search circuit 4.
7 and thereby open tape recorder 1
The tape is run in fast forward or rewind.

The counter value from the linear counter is stored in the counter storage unit 3.
When the counter value of the memory byte of the first selected song, which is the search target in step 8, becomes one second, the judgment (comparison) circuit 46 detects this and takes out the detection signal, and the play/fast forward step 7 A play drive signal is taken out from the rewind search circuit 47, and the open tape recorder 1 enters the play state from the fast forward or rewind mode.

The beginning signal of the first selected song is extracted from the reverse head 20 during dubbing play to a cassette tape, and is supplied to the binary counter 50 via the terminal P1 amplifier 49 of the analog switch 15. Three pulse signals are counted, H level signals are taken out from output terminals QA and QB, and an H level signal is taken out from AND circuit 61a.

A drive signal is taken out from the recording drive circuit 43 by this H level signal, and the cassette tape recorder 2 changes from the pause mode to the recording play mode, and at the same time, the play mute release circuit 48 of the open tape recorder 1 is activated to play mute. is released and open tape recorder 1
The first selected song recorded on the open tape is dubbed onto the cassette tape of the cassette tape recorder 2.

When the tail signal recorded at the end of the first selected song, that is, the two pulse signals, is taken out from the reverse head 20, an L level signal is output from the output terminal QA of the binary counter 50, and an H level signal is output from the output terminal QB. , an L level signal is taken out from the AND circuit 61a, and an H level signal is taken out from the AND circuit 61b. The signal is supplied to a recording mute drive circuit 75, a recording pause drive circuit 51, and a determination (comparison) circuit 46.

As a result, the drive signal from the recording drive circuit 43 disappears, but the recording mute drive circuit 75 is activated and the tape recorder 2 enters the fish signal recording state for 4 seconds, and after 4 seconds, the pause signal is taken out from the recording pause drive circuit 51. The cassette tape recorder 2 temporarily enters a recording pause state 4 seconds after the station signal is detected.

On the other hand, the counter storage unit 38 is configured to count +1 by an H level signal from the monostable multivibrator 74 and sequentially transfer the stored time to the general-purpose register from the upper storage byte. A signal from the vibrator 74 determines whether the counter value of the storage byte corresponding to the second selected song stored in the counter storage unit 38 and the counter value indicated by the linear counter of the open tape recorder 1 are determined ( Comparison) circuit 46 compares the comparison output signal, and this comparison output signal is supplied to the play/fast forward 7 rewind search circuit 47 in the same manner as in the previous case, and is opened in the same manner as in the previous case 4 seconds after the previous station signal is detected. The tape recorder 1 enters the fast-forward or rewind mode to search for the second selected song, and the counter value from the linear counter is greater than the counter value of the storage byte of the second selected song in the counter storage unit 38. When the seasonal second comes, the open tape recorder 1 enters the play mode, and the second selected song is dubbed onto the tape of the cassette tape recorder 2.

Thereafter, by repeating the above operations, the selected songs are sequentially dubbed onto the tape of the cassette tape recorder 2 according to the order.

In this way, the songs recorded on the tape of open tape recorder 1 can be rearranged according to the selected order and dubbed onto the tape of cassette tape recorder 2, and the songs on the tape of open tape recorder 1 can be dubbed. Since the beginning and end station signals are recorded at the beginning and end, respectively, unnecessary announcement contents recorded between songs are not recorded on the tape of the cassette tape recorder 2, and only desired sections can be dubbed.

In addition, in addition to the case where the selection order of song numbers is to select gradually increasing song numbers such as '1.3.7.10J', rl.

Even when selecting a track number whose order is fixed, such as 7 or 3.2, the counter value of the selected storage byte stored in the counter storage section 38 and the open tape recorder 1
By comparing the counter value indicated by the linear counter, the tape of the open tape recorder 1 can be fast-forwarded or rewound to the selected track number.

In addition, when dubbing songs in order such as ``1.2.3.4...Yo'', the light pen 4 picks up the song numbers and sends a predetermined signal to the counter storage sections 29, 3B.
Similarly to the above case, the counter value corresponding to the selected song stored in the counter storage unit 38 and the counter value of the linear counter of the open tape recorder 1 are determined by the judgment (comparison) circuit 46. The signals are compared and a play mode signal is generated, and the open tape recorder 1 searches for a song in the play mode and enters the playback state.

OK monitor Next, a display called OK monitor will be explained.

From the cassette tape recorder 2, the power on/off status of the cassette tape recorder 2, whether the cassette half is installed or not,
Information signals corresponding to whether the recording is possible or not are supplied to the OK monitor storage section 52, and the open tape recorder 1 also outputs information such as turning on/off the power of the open tape recorder 1, setting the tension arm or not, and turning on the source/tape switch. Information signals corresponding to the connection states to the terminals, etc. are supplied to the OK monitor storage section 52 and stored therein, and further supplied to the video RAM 28 so that these O signals can be sent to the receiver 3.

At this time, if the power is turned on and off normally, 'OK' will be displayed after this item, and if the power is turned off, '1?' will be displayed after this item. ? A message will be displayed.

In addition, item 17 above? The ``Y'' display is configured to automatically switch to ``OK'' in response to activation by individual operations such as turning on the power or loading a cassette half.

In addition, a color composition circuit (or blinking circuit) 64 is connected to the OK monitor storage section 52, and the above 1? ? A predetermined color may be displayed only in the row of the item marked as ``Y'', or the item may be displayed blinking.

Thereby, the operator can easily confirm the status of the open tape recorder 1 and the closed tape recorder 2, and can check the status of these tape recorders before dubbing.

In addition, the modes of the open tape recorder 1 and the cassette tape recorder 2 are detected by the operating state detection circuits 59 and 60, respectively, and are supplied to the video RAM 28 to be displayed on the receiver 3, such as 'PLAY'.

By displaying the characters ``REC'', the mode of the tape recorder can be easily confirmed, and accidents such as erroneously switching to another mode can be prevented.

Playback of Cassette Tape Next, a case will be described in which the songs dubbed on the tape of the cassette tape recorder 2 are played back in order or with the order changed.

When the switch 67 provided on the controller 6 is rotated to the cassette monitor mode R3 and the cassette monitor switch 66 is closed, a signal is taken out from the drive circuit 44, the cassette tape recorder 2 enters the playback state, and the tape starts running. be done.

As a result, the information signal of the song title recorded as an FM signal at the beginning of the tape is extracted in the order of the songs selected and recorded first, demodulated by the FM demodulation circuit 53, and then sent to the serial/parallel conversion circuit 54. After being converted into a parallel signal, it is sent to the video RAM via the character generator 42.
28, and the song title is displayed on the receiver 3 again.

At this time, since the end signal is recorded on the cassette tape at the end of the song title information, this end signal is detected by the end signal detection circuit 62 and turned into a stop signal by the drive circuit 44, which causes the cassette tape recorder to 2 is temporarily in stop mode.

Here, when the light pen 4 picks up the desired playback songs in accordance with the desired playback order, this signal is supplied to the cassette playback order storage section 55 via the command decoder 33 and stored therein, and is further judged (compared). The signal is supplied to the circuit 57 and the drive circuit 44, thereby placing the cassette tape recorder 2 in fast forward or rewind mode.

On the other hand, the number of unrecorded portions on the cassette tape is detected by the song interval detection circuit 56, and the number of unrecorded portions is counted by the song interval counter 63.

The inter-song counter 63 is set to count by 1 when the cassette tape recorder 2 plays back a song title and enters the stop mode, and a signal corresponding to the number of unrecorded portions is supplied to the comparison circuit 57 for judgment. (Comparison) In the circuit 57, this signal is compared with a predetermined signal corresponding to the track number stored in the cassette playback order storage section 55, and when the signal from the storage section 55 and the signal from the counter 63 match, it is detected. A signal is taken out and supplied to the drive circuit 44, whereby the cassette tape recorder 2 changes from fast forward or rewind mode to a play state and a desired song is reproduced.

When a desired track is picked up with the light pen 4, for example, "29"s, n9? is displayed on the line marked ■ on the screen of the receiver 3, as shown in FIG. . . . Since a display such as ``Y'' is displayed, it is possible to determine which song is to be played.

When the playback of the song is completed, a detection signal obtained by counting the number of consecutive unrecorded portions is supplied to the judgment (comparison) circuit 57, where it is compared with the signal from the storage section 55 and the tape is moved to a predetermined position. In the same manner as in the above case, the cassette plays a song stored in the playback order storage unit 55 and searches for the song, and the desired song is played.

At this time, the inter-song counter 63 also operates during fast-forwarding or rewinding, but the cassette playback order storage section 55 takes out a signal instructing the reading of the next track number only when an inter-song interval is detected during play. It is configured as follows.

This is done by configuring the time constant in the inter-track detection circuit 56 to be different during fast forwarding or rewinding and during play, so that only the detection output obtained during play is supplied to the cassette playback order storage section 55. Just configure it.

In this manner, by picking up the songs displayed on the receiver 3 with the light pen 4, desired songs can be reproduced from the dubbing tape in a desired order.

During this playback operation, the signal of the track number being played is taken out from the cassette playback order storage section 55 and supplied to the color synthesis circuit (or blinking circuit) 58 to obtain a predetermined signal. The number of the song being played, the name of the song, and the required playing time are displayed, and the line is displayed in a predetermined color, or the text is displayed in color, or the text is made to blink, so that you can see which song is being played. It can be easily confirmed that

As described above, the tape recorder of the present invention connects the recording path and the reproducing path to the incoming head via a switch that selectively connects the recording path and the reproducing path for control signals, and The outbound playback head plays back the information signal recorded on the track, and the return head records the control signal on the return track, and the return head plays back the control signal.
