Description

[Detailed description of the invention] The present invention relates to a tape recorder equipped with functions for automatic song selection and creation of unrecorded sections (or recording of cue signals).
Both functions can be operated using a switch from a single operating section.

2. Description of the Related Art In a tape recorder, it is common practice to detect a no-signal portion between songs so that a plurality of pieces of music recorded on a tape can be selected.

On the other hand, in order to select songs, unrecorded sections are often created between songs when recording music.

Therefore, some tape 0 recorders detect this no-signal section between songs and automatically stop tape running.
Alternatively, there are devices that have both the function of automatically reproducing a preset song and the function of creating a no-signal section for this purpose.

However, in conventional tape recorders of this type, a switch for selecting music or not and a switch for creating a non-recording section are provided separately, so these two switches are located on the front panel of the tape recorder. Since each control knob is provided, the operation section is very complicated, and there is a risk of erroneous operation.

The present invention is intended to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

Reference numerals 1 and 1' designate recording input sections, from which signals are supplied via a recording amplifier 2 and an equalizer section 3 to a recording head 4, from which recording is performed on a tape.

5 is a reproducing head, and the signal from this is sent to a reproducing amplifier 6.
, are supplied to the output terminal 8 via the line amplifier 7.

9 is a no-signal portion detection circuit for automatic music selection, and 10 is an operation switching means such as a plunger operated by the output of the no-signal portion detection circuit 9.

Reference numerals 11a and 11b are selector switches that are linked to the recording/playback selector switch, and the illustrated state shows the recording mode, and 12a and 12b are switches that are linked to each other for automatic music selection on/off and for creating an unrecorded section. Both switches 1
2a and 12b are operated by a single operating knob 12, the switch 12a works as a switch for creating an unrecorded section during recording, and the switch 12b works as an automatic music selection on/off switch during playback.

If the operating knob 12 is operated to close the switches 12a and 12b in the recording state, the output side of the recording amplifier 2 is grounded via the switch 12a and the selector switch 11a, so the recording signal is not supplied to the recording head 4. Therefore, the switch 12a.

A non-recorded portion is formed on the tape during the period when the tape 12b is closed.

Incidentally, even if the switch 12b is closed while the operating knob 12 is being operated, this does not cause any problem since the switch circuit is kept open by the changeover switch 11a.

Next, when the switches 12a and 12b are closed by the operation knob 12 in the playback state in which the changeover switches 11a and 11b are changed from the illustrated state, the playback signal from the playback head 5 is transferred to the switch 12b1 changeover switch 11b.
The signal is also supplied to the no-signal portion detection circuit 9 via the no-signal portion detection circuit 9, where the no-signal portion between songs is detected and the operation switching means 10 is activated.

Although the switch 12a is closed in this playback state,
Since the switch circuit is opened by the changeover switch 11a, there is no influence on the recording circuit system.

Here, the detection of the above-mentioned no-signal portion is of course possible because the playback head 5 is in contact with the tape in the playback state, but the playback head 5 can be brought into contact with the tape during fast forwarding or rewinding operation. Alternatively, by providing a dedicated reproducing head for detecting no-signal portions, the no-signal portions can be detected in the same way during this fast-forwarding or rewinding operation.

Then, each time a no signal is detected in this fast forward or rewind state, for example, the tape advance is stopped or the tape is automatically shifted to the play state, and in addition, the tape is stopped or played in the same way when no signal is specified in advance. .

Although the above embodiment has been explained using a Q7 recorder in which the recording circuit system and the playback circuit system are provided separately, the same applies to a tape recorder in which the recording circuit and the playback circuit are also used by a recording/playback head. be.

As described above, the present invention has a switch that creates unrecorded areas during recording and a switch that detects unrecorded areas during playback and selects whether or not to perform automatic song selection. Therefore, unlike conventional tape recorder operation knobs, there is no need for separate knobs for each operation, thereby simplifying the operation section and eliminating the risk of erroneous operation.

In the above description of the present invention, the unrecorded part and its detection have been described, but the unrecorded part is equivalent to a cue signal, and the detection of the unrecorded part is equivalent to the detection of a cue signal. The same applies to this method as well.

Claims (1)

[Scope of utility model registration request] A switch for forming a non-recording section (or recording a cue signal) on the tape during recording and a switch for selecting whether or not to detect a non-signal section (or cue signal) during playback are interlocked, and both switches are operated in conjunction with each other. A tape recorder configured so that it can be operated with a single operating knob.
