The present invention will be described below with reference to drawings of embodiments.

The drawing shows an example of the configuration of the tape recorder of the present invention, and in the drawing, reference numerals 4 and 7 indicate recording/reproduction changeover switches, which are currently in the recording position. Therefore, a recording signal from a signal source 1 such as a record player is amplified by the recording amplifier 5, applied to the recording/reproducing head 3 via the recording/reproducing switch 4, and recorded on the magnetic tape 2 in the constant speed running mode. On the other hand, the recording signal is sent to a low frequency amplifier 8 via a recording/playback switch 7.
The signal is amplified by the speaker 9 and monitored by the speaker 9. At the same time, the recording signal is detected by a song interval detection circuit 10 at an arbitrary song interval, and the detected signal is applied to a control signal generation circuit 11. When the upper recording/reproducing switches 4 and 7 are in the playback position, the reproduction signal from the recording/reproducing head 3 in contact with the magnetic tape 2 in constant speed running mode is applied to the reproduction amplifier 6 through the recording/reproducing switch 4, and the reproduction signal is applied to the reproduction amplifier 6 through the recording/reproducing switch 4. The signal is amplified by an amplifier 6 and applied to a recording/playback switch 7. The reproduced signal from the upper recording/re-switching switch 7 is amplified by a low frequency amplifier 8 and amplified by a speaker 9. At the same time, the reproduced signal is detected by a song interval detection circuit 10 at an arbitrary song interval, and the detected signal is applied to a control signal generation circuit 11. The above-mentioned song interval detection circuit 10
detects the song interval of the input recording signal or playback signal based on the specified signal from the song number setting device 12 provided elsewhere, and outputs the detection signal only when the song interval of the specified song number is detected. is applied to the control signal generation circuit 11.

The control signal generation circuit 11 responds to a detection signal input based on a designation signal from a mode setting device 13 provided elsewhere, and applies a command signal to the control circuit 14 according to the designated mode. The control circuit 14
For example, three plungers 15, 16, 17
and reel motor 18, capstan motor 1

5 is off, and the reel motor 18 is controlled to be in the normal rotation state. In the recording mode of the magnetic tape 2, the plunger 16 and the capstan motor 19 are controlled to be on, the plungers 15 and 17 are off, and the reel motor 18 is in normal rotation. In the fast-forward reproduction mode of the magnetic tape 2, control is performed so that the plungers 16 and 17 are turned on, the plunger 15 and the capstan motor 19 are turned off, and the reel motor 18 is rotated forward. In addition, in the rewind playback mode of the magnetic tape 2, the plungers 16 and 17 are turned on and off.
The plunger 15 and the capstan motor 19 are controlled to be turned off, and the reel motor 18 is controlled to be reversed. Moreover, the above magnetic tape 2
In the playback pause mode, the plungers 15, 16, 17 are turned on, and the reel motor 1 is turned on.
8. Control the capstan motor 19 to be in each OFF state. In addition, in the recording pause mode of the magnetic tape 2, the plunger 1
5 and 16 are turned on, and the plunger 17, the reel motor 18, and the capstan motor 19 are turned off. Further, in the fast forwarding mode of the magnetic tape 2, the plungers 15, 16, 17 and the capstan motor 19 are controlled to be off, and the reel motor 18 is controlled to rotate normally. Further, in the rewinding mode of the magnetic tape 2, the plunger 1
5, 16, 17, the capstan motor 19 is controlled to be off, and the reel motor 18 is controlled to be in the reverse rotation state. In the stop mode of the magnetic tape 2, the plungers 15, 1
6, 17, the capstan motor 19, and the reel motor 18 are controlled to be in the OFF state.

Here, each mode of rewind playback and fast forward playback is achieved by rotating only the reel motor forward or reverse while the head remains in contact with the tape, and is realized by a known method. The settings of the song number setter 12 and mode setter 13 are stored in, for example, a semiconductor memory, and each time a song interval is detected, it is checked whether or not the set song number exists, and the set mode is selected. It is composed of

In such a configuration, now the track number setter 12
The mode setting device 13 sets the recording pause mode in response to the third song designation by the song number setting device 12, and the recording pause mode is set in the mode setting device 13 in response to the fifth song designation by the song number setting device 12. It is assumed that the mode is set and the stop mode is set using the mode setting device 13 in response to the sixth song specified by the song number setting device 12. Then, when the recording mode is set using the mode setting device 13 and a start command is given at the same time,
In accordance with the recording mode start command from the control signal generator 11, the recording mode is started, and the recording signal from the signal source 1 can be recorded on the magnetic tape 2. When the song interval detector 10 detects the third song interval of the recording signal, the control signal generator 11 issues a preset recording pause mode command to the control circuit based on the detection signal. 1
4 and pauses and waits in the recording state. Next, when the song interval detector 10 detects the fifth song interval of the recording signal, the control signal generator 11 gives a preset recording mode command to the control circuit 14 based on the detection signal. , the recording state is restarted, and in that state the sixth recording signal is
When the song interval detector 10 detects the second song interval, the control signal generator 11 gives a preset stop mode command to the control circuit based on the detection signal, and the magnetic tape 2 of the recording signal is Stop recording to. Therefore, the magnetic tape 2 has 1
~3rd and 5th songs can be recorded.

It is also assumed that the rewind playback mode and the stop mode are set in response to the third and second song designations by the song number setter 12. And mode detector 13
When a command to start recording is given in , after recording up to the third song, it is possible to rewind and play back up to the second song, and in this rewind playback mode, when the second song interval detector 10 detects, It can be stopped. Therefore, the third song can be played back and recorded with corrections.

Depending on other mode settings, it is possible to realize automatic recording such as automatic recording end, end rewind, and rewind play after end.

As described above, the tape recorder of the present invention detects the song interval of the recording signal from the signal source to be recorded based on the specified signal from the song number setting device, and detects the song interval of the specified song number. A song interval detection means that outputs a detection signal only when a detection signal is detected, and a command signal for outputting a command signal for realizing a mode according to a designated signal from a mode setting device in response to the detection signal from the song interval detection means.
